Early Weaning
A Good Bet for Beef Producers in Drought-Stricken Areas

CowsAt the beginning of 2013, cattle ranchers in the Northern Plains were among U.S. agricultural producers still feeling the lingering effects of the sweltering 2012 drought, the worst in half a century.
Beef cow numbers were at the lowest in 50 years as U.S. beef producers—severely affected by extended drought—tried to recover from some of the driest months on record.

Across the Northern and Southern Plains, beef producers hit the hardest by drought are threatened by limited forage resources for cows, which restricts calf growth, resulting in lighter calf weaning weights. In addition, drought can decrease cow body weight and condition and weaken immune functions that may affect overall health and reproductive performance.
For decades, scientists at the Agricultural Research Service’s Fort Keogh Livestock and Range Research Laboratory (LARRL) in Miles City, Montana, have studied management options that minimize the effects of severe drought on rangeland livestock production. Recently, LARRL animal scientists Richard Waterman, a rangeland nutritionist, and Thomas Geary, a reproductive physiologist, teamed with local ranchers and collaborators at Montana State University (MSU) and the American Simmental Association in Bozeman, Montana, to evaluate early weaning of beef calves and its impact on cow, heifer, and steer performance.

“When a calf is weaned early, all nutrients that normally go to milk production for the calf can be retained by the mother—helping to increase or sustain her body weight and condition,” Waterman says. “And proper handling of early-weaned calves can result in greater weight gain than if they had remained with their mothers, especially during drought.”

Tallying the Benefits
Scientists confirmed that weaning a calf earlier than normal potentially offers a beneficial production alternative for beef producers when forage is limited.
“With the calf removed, the cow needs less forage to address her needs, which is especially important during drought,” Waterman says.

“Another issue with drought is the inability to grow enough summer and winter forage for cattle,” says rancher and collaborator Dean Peterson, who volunteered his cow/calf herd in Judith Gap, Montana, for the project. “We used to run 500 cows, but now we run 400, because it’s about maximizing the efficiency of the forage. We suffered an initial loss of income, but we’re doing a better job at taking care of the land and cattle, and our operation is sustainable for the long term.”

Research was conducted using calves from both Judith Gap and LARRL. Some calves were weaned early, at 80 days of age, while others were weaned at the more traditional age of 215 days. Cows that weaned a calf early weighed more and were in better body condition at the start of winter. Consequently, the amount of harvested feedstuffs required for cows to maintain satisfactory body weights and condition throughout winter was reduced.

“We learned a lot,” Peterson says. “The research confirmed that early weaning is profitable. If you wean calves early, you have fewer problems and can better control the production environment.”
“Early weaning during severe droughts will reduce economic losses that would occur when selling lightweight calves,” Waterman says. “In order to achieve an economic benefit, a 20-percent increase in reproductive performance in the cow herd would need to be realized, because early-weaned calves must go on feed much sooner.”

Outcomes of the research also demonstrated that early weaning increases the probability of heifers becoming pregnant on time in the following breeding season, Waterman says.

“The nice response was in body weight, especially with those 2-year-olds nursing for the first time,” he says. “It takes a cow 5 years to reach her mature body weight. When young cows have their calves removed early, the demands of lactation cease—allowing the cow to focus her resources on body condition and growth. If a cow goes into winter in better condition, maintains that condition, and calves with better condition the next year, she will be much more likely to remain in the herd until maturity.”

The objective is to preserve body condition of the cow at a time when forages are limited, says John Paterson, a former MSU animal science professor and Extension Service beef cattle specialist. “We don’t want cows to get thin or pull body condition down, because they’re lactating, which requires a lot of feed. The way you save that feed is to stop lactation by getting the calf weaned earlier.”

Steering in the Right Direction
Additional findings showed that early-weaned steers reached maturity sooner than traditionally weaned steers when weight gain, feedlot performance, and carcass traits were measured. Steers had a higher rate of growth between the time of early weaning and the time of normal weaning.

Early-weaned steers typically had poorer USDA yield grades, revealing the importance of identifying them before they enter the feedlot, Waterman says. While producers who market cattle using a quality grid will benefit from having a higher quality carcass going into market, research indicates that management of early-weaned calves can directly affect how they are graded at harvest.

“Carcasses of early-weaned steers may be too fat and receive less-desirable USDA yield grades compared to those of traditionally weaned calves of similar genetics and age when harvested together,” Waterman says. “If early-weaned steers are identified before entering the feedlot and harvested at an earlier age, producers have the opportunity to market them at more desirable yield grades with increased quality premiums for those carcasses.”

Partnering with the University of Illinois, scientists confirmed this strategy by using ultrasound to measure carcass characteristics. Early-weaned steers were then harvested at a younger age than traditionally weaned animals to maximize their carcass value.

“This research involved cattle that were on Montana ranches, so it was the real deal,” Paterson says. “When you wean earlier and get those cattle into the feedlot, the quality and yield are very nice. A lot of ranchers have figured that out, because it’s an economic issue as much as anything else.”

Peterson is among those ranchers. “We went far enough into the study to get the benefits on the other end,” he says. “We had better cattle with early weaning because it helped our quality too. And because we retained ownership of all our steers and heifers until slaughter, we were able to realize those premiums. We had better carcasses when we weaned earlier.”

Study English at a level you feel slightly challenged with and your English will improve daily. We encourage comments and suggestions at Larisa English Club.com.

What is the best way to learn and remember English? Simple! Teach others. What do I mean by “Teach others?” That is simple to!

Learn English by teaching your friends and family what you have learned. Do it over and over, it will stay with you for a long time, maybe forever!

Study the areas of English that interest you the most. Surprisingly, you will learn other parts of English too.

All learners of a foreign language must remember that repetition is key to memorizing what you study. Studies have shown that it takes an English learner an average of seventeen interactions with specific elements to make that knowledge stick. In other words, after being exposed to a certain part of just about anything including English, you will most likely not forget soon.

What is the best method to study and learn great English? The truth is; There isn’t just one! Facts are facts. Everyone learns differently.

Some students like reading. Some like listening. Some like lecturing. It is all about you and what interests you. I can tell you from personal experience teaching English over nine years, no two people are the same.

That said, most successful learners of English, do it by teaching others first. The second best way might be when we speak to others. Group discussion is an important element to speaking.

Without practice and some challenges, students learn to speak fluently slower. If you want to speak great English, practice speaking with others.

Don’t forget, learning the basics in English should always come first for a second language. Speaking can also be incorporated in your English study at the earliest stages of your learning journey.

There is one great way to evaluate your English. It is simple called “Progress”. With progress you are moving ahead and towards new elements in English. If you have to relearn today what you learned yesterday, you have work to do.

The main idea is to make daily progress. If you are making daily progress, you are doing it right. For students who feel they are standing still with English, try something different.

It might be your study habits or one of many other factors. Just take a look at what you are doing everyday and just know that progress is the key to learning and speaking great English.

Once you have studied and learned the basics in English grammar, now it is time to practice, practice, practice. This is always a great idea with friends, family and colleagues.

They help you and you help others. Speaking fluency should be your number one goal. Proper pronunciation is also key to speaking understandably.

Some students and teachers believe that English can be studied and learned without grammar. This is simply not true. Many students are told this by teachers who don’t know grammar either.

This is very dangerous. Not knowing grammar before trying to use it in spoken English is always a bad idea. Once a student buys into this idea of speaking without grammar, he or she always forms nasty habits. Most of the time, these habits are impossible to break.

At some stage in your study of English, you will get to a point where you have a mountain of questions. This is often one of the last stages in English. This is when you need to work with an English teacher that can answer those questions.

This can only be done by someone who is qualified, confident and experienced. Never trust an unqualified person to teach you English or answer your questions.

Work with a qualified English teacher who will answer your questions accurately with confidence.

One important key to learning better and better English is continual exposure to the language. This can be a number of different ways but, do what is best for you. Is it music? What about watching your favorite sitcom? Does your spouse speak English?

Can you practice together? While there are many ways to learn just about anything, practice and being around others is one of the best methods of attaining English proficiency.

Once you feel confident that you have learned as much as needed to achieve your goals, now it is time for more vocabulary. Vocabulary along with speaking English is essential.

When you get to the Intermediate level of English, study new vocabulary daily. Look for three and four syllable words. As we climb that ladder of English proficiency, we need to speak and understand others.

Native speakers of English as well as advanced ESL students speak with words that might be more specific in meaning. To better understand others, you need vocabulary.

Remember, words are just words until you decide how to use them. Most nouns can be used as verbs while many verbs can also be used as nouns. A word is just a word until you decide what job to assign it.

The same goes for all words in English. Most people know the word “Yes” as an adverb. Did you know it is also a noun. Just like all words in English that follow the “Article” as a single word, it is a noun.

Verbs, Modifiers and Adjectives work the same way. To play the record (Noun) or to record (Verb) or to happen in a record time (Modifier). Another example might be the word “Live”. To live (Verb) in a country or to attend a live (Adjective) concert.

Remember that a word is just a word until you have decided how to use it in a statement. The usage and pronunciation might change.

What is the best way to study English? As mentioned before, there isn’t one. That said, for most people who study with a private tutor, progress is often faster. On-line lessons are another great way to study as well.

For those who like or need the interaction in a classroom with others, group study might be best. A professional private language school should offer, private, semi-private, mini-group and group lessons.

Remember that many schools refer to an hour of English as an academic hour. An academic hour of English is just 45 minutes. Professional private language schools always teach a full 60 (Sixty) minutes for each lesson.

The Antarctic is Turning Green
Larisa Article written by Billgreen54 ESL Tutor


The Antarctic is Turning Green

Ian Johnston Independent Environment Correspondent

Scientists say the frozen continent is likely to ‘alter rapidly under future warming, leading to major changes in the biology and landscape of this iconic region. The Antarctic is turning green with rising temperatures having a “dramatic effect” on the growth of moss in the frozen continent, scientists have discovered. Since 1950, temperatures in the Antarctic Peninsula have risen by about half a degree Celsius each decade. This is much faster than the global average.

The Antarctic

Growth rates of moss since 1950 have been running at four to five times the level before. This is according to a study by UK-based researchers who studied three sites across a 1,000km stretch of the peninsula. In addition to climate change, the extinction of animal species is prolific. Plastic waste, fossil fuel ash and radioactive particles from nuclear bomb tests will all leave a permanent record in the planet’s future rocks.

“Between 1950 and 2000, temperatures increased by half a degree per decade on average,” said Dr Amesbury of Exeter University. “The reason we are so confident the moss is responding primarily to temperature, is because of the wide-scale response we see in our moss banks from three different sites that stretch 1,000km across the Antarctic Peninsula.”

The researchers who reported the results of their study in an open-access paper in the journal “Cell Biology”, also looked into how sensitive the moss would be to further warming.

“The results of that analysis lead us to believe there will be a future ‘greening’ of the Antarctic and a further increase in moss growth rates. “We are likely to see massive amounts of moss colonizing new areas of ice-free land created by the warmer climate.

Land Discovery of The Antarctic in 1675

Thank you Wiki.

The first Antarctic land discovered was the island of South Georgia, visited by the English merchant Anthony de la Roché in 1675. Although myths and speculation about a Terra Australis (“Southern Land”) date back to antiquity, the first confirmed sighting of the continent of Antarctica is commonly accepted to have occurred in 1820 by a Russian expedition. The first human born in the Antarctic was Solveig Jacobsen. He was born on 8 October 1913 in South Georgia.

Scientists in the Antarctic

The Antarctic region had no indigenous population when first discovered. It’s present inhabitants comprise of just a few thousand transient scientific and other personnel. They work on tours of duty at several dozen research stations maintained by various countries. However, the region is visited by more than 40,000 tourists annually, the most popular destinations being the Antarctic Peninsula area (notably the South Shetland Islands) and South Georgia Island.

In December 2009, it was noted that the growth of tourism, brought along with it, consequences for both the ecology and the safety of the travelers in its great and remote wilderness. This was at a conference in New Zealand conducted by experts and signatories of the Antarctic Treaty. The definitive results of the New Zealand conference were presented at the Antarctic Treaty states’ meeting in Uruguay in May 2010.

Leading statements and questions

For learners of a second language, sometimes, dialog or conversation can be difficult.

For learners of a second language, sometimes, dialog or conversation can be difficult. Conversation engagement, is not that difficult with a few simple tricks. Asking a simple question to start out a conversation is easy with simple question words. I covered question words in a previous English Club.

Question words are often needed to carry on a conversation. The idea is to ask questions connected to details already mentioned. Try to do this while the other person is speaking. This is easy by visualizing objects and situations that are connected.

I call these “Leading Statements and Questions”. It is all about dialog and how to continue a conversation. Now, we go back to those questions words and how they connect. Here’s an idea and example. “What is your favorite food?”. An answer might be “My favorite food is pizza”. Now visualize in your thoughts “What kind of pizza do you like?”. Another question could be; “How often do you eat pizza?” or “Where do you eat pizza?” or “What is your favorite pizza?” or “Why is pizza your favorite?”

You can ask many questions with question words with leading questions and visual thoughts. Here! Take a look at a few examples with our speaking practice…

Basic Grammar Review

Prepositions of Place, Movement and Time

Classroom posters are another way for students to learn from and have a reference point when working with a teacher and fellow students.

English prepositions are always fun to learn. It helps if a teacher has classroom teaching aides to assist with examples. Classroom posters are another way for students to learn from and have a reference point when working with a teacher and fellow students.

English prepositions are all about place, movement and time. Before getting started with prepositions, there are two important words to teach as thoroughly as possible.

Start with the word “Arbitrary”. The word arbitrary is used when we refer to something when relevance is not exact. In this case, the word’s “something or anything are indefinite”.

The main objective here is to help students better understand that, when describing with prepositions, often there is more than one choice. In other words, examples like “Please sit near the table or by the table” have little difference in meaning. The main idea is to learn how to communicate. If we both understand what the other is saying; isn’t that perfect English? Or better yet! Perfect communication.

The second important word to learn is “Collocation”.

The second important word to learn is “Collocation”. Collocations or colloquial speech is when we use words in a certain order that are common in English. Commonly spoken word combinations are easier to understand than one might think. Collocations can be used many different ways in English. Common statements, phrasal verbs and the list goes on and on.

 One of the best ways to teach collocations and common word order is with a list of examples. This is done in order of importance. In other words, start by writing a simple statement with the most popular word combination or collocation. Examples might include, “Please have a seat at the table” or “Please have a seat by the table”.

Although these statements mean two different things, they are used universally. The main idea here is “Which word combination is used more commonly?”. Please sit “AT” the table is more common compared to; Please sit “BY” the table. Therefore “AT” is more common compared to “BY”.

Can we use both examples? Yes! Why? Because, I understand you!

Typical time expressions are all about colloquial speech. Place and movement prepositions are generally specific to places and movement but, many can be interchanged.

This is due to the difference between perfect grammar and spoken English. Again, it is often more important to communicate understandably, than to attempt to speak perfect English.

So, which prepositions are the ones we should start with and why teach prepositions in chunks? There are three to start with. Those would be “At, In, On”. These are the three most common prepositions. One of the best ways to learn prepositions is to connect them with understandable words. In other words; Vocabulary that you already know.

In English, there are many methods of teaching grammar. The main idea is to ask questions.

In English, there are many methods of teaching grammar. The main idea is to ask questions. Why do we use the word “AT?” “We use the word “AT” with locations or places”. Why do we use the word “IN?” “We use the word “IN” with limits”. Why do we use the word “ON?” “We use the word “ON” when two things touch”. These are common examples and general thoughts. There are exceptions to just about every rule in English. Just remember collocations and flexible English.

Choose other preposition words to chunk together and form common ways to describe identical situations. All students need to know that while all speech is important, the main goal should always be understandable communication. If an expression or statement is not perfect English but, the other fully understands your statement, isn’t that perfect English?


English Grammar

Reported Speech

A few simple thoughts about “Reported Speech”. There are two ways to report what happened or what someone said, “Direct Reported Speech” and “In-direct Reported Speech”.

Direct reported speech is used when we use the same tense when stated. In other words, if someone says “Hello”, we can refer to the statement with something like “He says hello!”. In this example, we use the same tense as what was said.

“Indirect reported speech” is when we refer to a statement or fact from the past and go back one tense in our statement. So, if someone said “I am hungry” we would say “He said he was hungry”. Notice how the verb “To be” changed from “Am to Was”. In this example, we went back one tense to refer to what was said.

Reported Speech

Another important element to “Reported Speech” is when we use “Modal Auxiliary Verbs”. In direct speech, we use the same modal verb used. In other words, if someone something like “I will go to work next week”, you report with the same modal verb. If you report with indirect speech, use “Would”. So, will to would, can to could, may to might and so on.

This is just a short explanation for reported speech. For more information regarding reported speech, look for grammar books at the Intermediate level and above.

Until next time…

I hope you enjoyed Larisa English Club number 5. Remember that “Life is an Adventure”. Live it to the fullest each and every day!
