Optimising milk fat strengthens dairy profits

Published on: 05/09/2018
Author/s : Stephen B. Blezinger 1, and Melina Aparecida Bonato, ICC Brazil. 1 Consultant for ICC Brazil.

Fat found in milk originates from three sources; de novo fatty acids synthesised in the milk gland of the cow (short-chain C4 to C14) comprise about 20-30% of total milk fatty acids, preformed fatty acids (long chain C18:0, C18:1 and C18:3) represent 35-40%, and the mixed group of fatty acids (C16) make up about 35%. Research has shown that the percentage of milk de novo fatty acids is positively...

Dr. Rahul S. Verma may be case of Degnala. Please check the mineral product composition & mineral status of soil in that area.

Dr. Rahul S. Verma No doubt there could be a number of causes. Evaluating the mineral program is an important first step and determining if the mineral mixture does, in fact meet the animal's requirements. I would closely look at Zinc, Selenium and possibly VItamins A and E.

Kind Regards,

Steve

And switch to a quality source of by-pass protein that serves other functions, and use highly-gelatinized starch to stimulate rumen microbial protein. One or two quality ingredients can take the place of many others.

The hormonal changes during pregnancy may be one of factor for the changes?
Since the animal being a heifer , the incidental changes may be found to be odd in nature.
This changes could be reversed after parturition and in one the dairy herd.

Dr. Verma, you could also check the status of copper. It is very common that color changes to red when there is a deficiency in cattle. You may need to do a liver biopsy for a micromineral count.

Dr Verma, depigmentation in buffaloes is primarily due to deficiency of copper and adequate exosure to sun light. Zn def will make the skin coat very rough and dry. Deworming can improve the shine on skin coat.

Sharma Madan Lal Depigmentation due Cu def should be diffused all over body not limited to switch of tail.

Dear Dr. Rahul S. Verma: Copper deficiency causing depigmentation of the hair coat most commonly is noted at the top of the shoulders, around the edges of the ears and around the muzzle in cattle with a darker hair coat. Lighter colored cattle may be noted by a drabness to the coat and general poor overall appearance. I believe, based on the description that an actual hair loss may be more related to zinc or possibly selenium and/or Vitamins A and E deficiencies although as someone pointed out, internal parasites can play a role here as well.

In general, for good health and production, all nutrients must be properly balanced and should consider all ingredients available in the diet.

Kindest Regards,

Steve

Even though the buffalo calves fed with green fodder has the patches on skin during summer, but it turns to normal after onset of the monsoon. It may be due to low mobility of the Zn & Cu in soil at low water table.

D.narayanasamy - there is an article here on Engormix that we published a few weeks back that discusses this topic. Here is the link to that article: https://en.engormix.com/dairy-cattle/articles/optimising-milk-fat-strengthens-t42055.htm.

Deficiency of various mineral ions in the body of the lactating animals reflect many ways. important is milk production, body weight and lather quality. We have developed mineral mixture to overcome the deficiency, witch can either mix with their food material or can dissolve in their drinking water. Results are very encouraging. It is to apply everywhere.

Feeding fat, specially bypass fat one month before calving prevents the ketosis which causes economical loss to the farmers.

Copper deficiency in livestock is easily detected just by seeing rough coat and loss of pigments in animals. When dewormers were not available 50 years ago traditional elders n bush doctors used to recommend in very light dose of copper sulfate and used to get successful results in getting rid of worms in animals. The article reconfirms the experiences of our elders about the role of copper in animal feed. It is really good article and I wish the author good luck.

Dear Hafiz Wasi Muhammad Khan! You are completely right! I use copper sulfate to prevent and treat anaplasmosis. Copper sulphate is the strongest cytoplasmic poison.

Mikalai Piasotski Sir, agreed beyond any reasonable doubt... I have tried copper sulfate in treatment of anaplasmosis in East Africa where this disease is commonly prevalent.

Sir, copper is not a panacea in the treatment of anaplasmosis. However, copper is a robust link in systemic work, including cobalt, zinc and other specific aspects.

Mikalai Piasotski maybe I could not explain what I wanted to say I consider cuso4 as a robust link.

We tend to believe that we should increase linoleic and linolenic acid in feed so that we increase them in milk fat to make milk and milk products more valuable for the consumer. However, we are creating trouble to the cow's metabolism and the consumer could easily balance out his LA and LnA requirement by taking a spoon full of them in the salad dressing.

The real unique fatty acids in milk are those Isomers of CLA. They can be increased in milk and they provide benefit to the consumer as science has shown. This is the ingredient which we should research for the benefit of our dairy industry and the consumer.

Control on ruminal acidosis and use of proper proportion of good roughage in feed are two important keys to get optimum fat level in milk.

Optimize your dairy milk fat and get more profit. Milk fat and protein are two key drivers of dairy profitability positively related to net milk income over feed costs. The quantity of de novo fatty acids reflects rumen functioning, especially fiber fermentation which produces acetate and butyrate, the building blocks of fatty acids.
Feed a well-balanced diet focusing on highly digestible fiber. Of particular importance is a physically effective fiber that promotes cud chewing.
