Introduction Many factors influence the composition of milk, the major components of which are water, fat, protein, lactose and minerals.Nutrition or dietary influences readily alter fat concentration and milk protein concentration. Fat concentration is the most sensitive to dietary changes and can vary over a range of nearly 3.0 percentage units. Dietary manipulation results in milk protein conce...

Type of feed additives can affect milk composition as methionine zinc, probiotics and calciumsoap of fatty acids.

And what about ratio in between by pass protein and by-pass, or by-pass energy and rumen degradable energy in supplementation?

Surely, inhibitors such as tannins in some animal feeds, including pistachio by-product can affect milk composition in dairy cows especially milk protein and fat .

I think Mycotoxin, Mycotoxicosis also contribute to change in milk composition, Specially on Fat%.

Forage: concentrate ratio is also an important factor.
If more forage more propionic acid and hence increased fat.
Also lactic acidosis do affect fat percentage

Also the length of the fiber affects (if long fiber increased fat percentage)

Good article about factors affecting milk composition of lactating cows. I want to know Wine and beer byproducts like Rice bran. Can malt in regular diet influence in increasing fat percentage in yielding milk? If yes, how and what should be the quantity to be given the two by products ( pl mention in kilogram ) to cattle having av. wt 250 kg?

How can we increase the milk fat content in a milking cow? One of my cross bread jercy cow's fat content is 1.7% to 2.2% only ( lactometer reading 30) in the morning. Please respond.

In answer to Ramanathanganesan query concerning low fat in milking cows. Dr. Looper's article adresses many of the factors and some were highlighted by other contributors. The first thing that springs to mind with low fat tests is the diet, a diet with a low ratio of roughage to concentrate or a ration that is too fine may result in a low fat test and should be one of the first areas to investigate, a couple of points to check ration and ration presented to cows - check NDF % in total ration, are cows sorting on the feed table, proper use of a mixer wagon - do not over mix or chop too fine. That said, there are also other factors to consider, Incomplete milking will depress fat test by leaving a considerable amount of fat rich milk in the udder (investigate milking vacuum and take-off of clusters).

this clearly shows that you are feeding more of grains than fodders.
to increase the fat% of the milk increase the dry fodder and reduce the grains in the feed. when you are feeding more of fibre content in the feed it will lead to increase of mastication which will lead to increase of fat% in your milk.

Numerous sources of fat in the diet can affect milk fat content and fatty acid composition.
