How can we nutritionally maximize true milk protein and milk fat of dairy cows?

Does anybody have practical advice for the dairy farmers like me, whose only roughage source is corn silage. And which amino acid we should add to our ration for 40 kg per day milk-producing dairy cows? Which amino acid are deficient in corn silage based rations? Dear friends, please give some advice. Knowledge is power and more powerful when shared with who had not. Please share some thoughts or experiences with amino acid balancing. God Bless you all.

Dear Jagadesh Singh Sandu,
Normally amino acids like lysine or methinine are not added in dairy cow rations in India because they are going to be broken down in rumen. Only protected amino acids are used in developed countries. Evonik has got some products having protected amino acids but not selling in India.
My experience in Punjab area tells me that, up to 50 litres production amino acids are not necessary.
Please review your feed formulation or TMR formulation. Check DMI and CP and starch levels in TMR. Also check for R;C ratio. Please talk to Mr Gulab Singh of CPF India Pvt ltd, Moga, Punjab.
He may be of helpful to you. In punjab silage has more moisture: more than 70% (70-80%)
So your cows may be eating more but not meeting the DMR. Protein requirement: 1g/kg B.W. and 90g/litre of milk. Please check these

Hi Jagdish Singh,

Balancing of amino acid is very much important in cow's diet to reduce feed cost and production cost for highly yielding animal. It becomes important for country like India, where good source for protein supplements are not available.

Whatever cow eat it breakdown in rumen and rumen bacteria grow and produce microbial protein with the help of degradable protein and fermentable energy. This microbial protein reach to intestine and available to absorb by blood in the form of amino acid., So we can say feeding of rumen protected amino acid is important rather than feeding of undegradable protein.

Sir, You have to add lysine and methionine are first limiting amino acid for cow. The cow's protein production is limited by the particular amino acid that is in shortest supply in relation to her requirement. That amino acid is called the "first-limiting" amino acid in the diet. You have to use or add only Rumen Protected Metioninr and lysine in Cow's TMR. You have to maintain the 3:1 for Lysine and Methionine in metabolizable protein.


STEPS FOR BALANCING AMINO ACIDS LYSINE AND METHIONINE IN DIET:
1. Calculate metabolizable protein requirement for cow.
2. After Metabolizable protein calculation actual lysine and methionine requirement are calculated as per NRC recommendations.
3. Lysine requirement -7.2% of MP (Metabolizable protein calculated).
4. Methionine requirement-2.4% of MP (Metabolizable protein calculated).
5. Calculate the available Lysine and methionine in TMR.
6. Calculate the additional requirement of Lysine and methionine = Total Requirement-Available in TMR.

Dear All, please pay attention to the product line of elagotannin-consist range with essential oils, acetate Na, and organic Zn: transit protein up, clostridia and somatic cells down, milk yield and milk protein up. We use it in different farms more than 3 years.

Selection of basal diet important is important for dairy cattle nutrition. If your basal diet is maize silage and it is harvested at appropriate stage and if you balanced concentrate having same bypass protein like fish meal then it can support 40-50 litre milk producing dairy cows. Rumen microbes have the capacity to synthesize essential amino acids if the diet is balanced with requiring nutrients with good quality basal feed.

If we add rumen protected protein, can we reduce crude protein percent in diet?

At the same time alive yeast product in 10g dose able to improve protein by 0,1-0,2%. Usually, it takes 3-4 weeks.

As it was absolutely important to have rumen-protected methionine and lysine, then how can we do this? What materials are beneficial to coat these important amino acids? Technology involved? Do we only go for Nanoparticle technology or there are much easier and economical ways to do coating of amino acids?

Could anybody guide me for this in the forum?

I am working for the last 45 years as a dairy consultant around the world in hot environments (desert, tropical and sub-tropical) with pure dairy cattle and cross. According to my experience the main incidence of the variability of the Fat and Protein in the milk is due to the type of breed and cross, the influence of the weather conditions and the feeding.
Using crisscross system as Holstein/Jersey or Holstein/Reed Swede and Holstein/RS/Montbeliarde the solid in the milk are much more stable in comparison with pure Holstein or similar breeds except Jersey.
In some experience in Pakistan with pure Holstein using Lysine and Methionine (from commercial brands) and in different doses and corrals of 120 cows each an average of 45 lit (same farm, formula and management) was not any evidence in the productivity or milk composition, and the fluctuation of the milk solid was similar in comparison with the corrals not treated.
When we evaluate the climatic conditions was noted that the moisture and temperature (moisture 80 to 90% and temperature +40 cent) have a direct influence on the fluctuation of the milk and composition. But this fluctuation is much less in the crisscross dairy cattle. Also noted that in dairy farms with pure Holstein in desert conditions the milk fluctuation is much less and more stable than in tropical and sub-tropical conditions, also if the temperature arrive to 45 degree or more.
In the feeding process, need to point out that the main factors noted is related to the Soybean Meal type and quality, (we need to remember that the soybean quality is influence from the cultivation to the processing) as an example that the soybean meal coming from USA or Argentina are the best quality for this reason. The selection of the soybean for feeding have an important role because is linked to the amino acid (need to remember that in the marked are different type of soybean), then the best is when the bypass arrives to 40% or more.
Formulation where the forage is limited to the use of only corn silo never will complete an appropriate balance of the feeding because will not fulfill the rumination process required by the cows, as well will not complete the bacteriological activity required into the digest system.
Cows are a rumination machine and need to respect this function to complete the nutritional balance. In the checkup of the cows after feeding I will advise having a 60% of the cows in rumination process, and the observation of appropriate manure conditions.
Alfalfa hay, corn silage, some wheat straw, selected soybean meal, DDGS, yellow corn, cottonseed whole, plus some other complementary feed and additives with cross cows, will be more than sufficient to produce 40 lit average. And is a good way to maximize the milk production.
I will not worry about Lysine and Methionine if I can formulate a good balance formula and I have a good performance of the genetic. Non-pure breed but good milking cows in hot environments.

I like very much this topic, thank you.

Looks written by a very very practical livestock farm manager who has experienced all these changes and recorded every variation. If I had to write on this topic, I would have concluded in almost same write up.

Very well narrated. I stess for 200 - 500 gms of bypass fat per animal yielding 40 lt and above to meet out the energy requirements. Hot climate reduces the feed intake and aminal exhibits symptoms like panting. We must immediately condense the feed by increasing the bye pass fat and proteins. I am consulting the high yielders farm for last 40 yrs.
Another important aspect is water intake. Animal must have taken 5-6 lt/ litre of milk and in addition 40 lts for metabolism. If it does not take that increase salt up to 3% of concentrate.
Improving and maintaining high production is a continuous activity and need almost daily attention.

Thanks for such a good topic. Soybean meal can be replaced by Roasted Guar Korma because it is higher in fat and also protein. Please guide for this.

As high yielders are fed high plain of nutrients with concentrate rich diet and there is every possibility of Ruminal Acidosis with high plain of concentrate and low roughages diet. It will be better if we supplement these high yielders with Rumen buffer along with yeast. The corrected ruminal environment will take care of optimum Milk Fat and SNF.

I think if you use buffer + yeast + essential oils + yucca, then you will get better results.

Dear Gustavo Pourraid
Thank you very much, it was great.

Sir, please, tell me what is the ideal feed formula for balancing amino acids.
