Problems solved by technology

At present, most CLA products are artificially synthesized, which are expensive, easy to oxidize, and are not suitable for direct consumption. Feeding dairy cows with protein materials with high CLA content can avoid the above shortcomings, which is an effective way. It is very necessary to regulate the incomplete hydrogenation of rumen by dietary composition and ingredients, and increase the content of conjugated linoleic acid in ruminant milk

[0023] Effects of adding RPAA to DDGS diet on performance of dairy cows and conjugated linoleic acid in milk Experimental animals and feeding management

[0024] The experiment was carried out in Harbin Xiangfang Dairy Farm from December 2009 to February 2010. Healthy and disease-free pre-lactating Holstein cows were selected with a body weight of 550±50kg, milk yield of 25±5kg, parity and calving date close to each other. 40 heads. From the pre-feeding period, a unified diet was fed, and three times a day (5:00, 11:00, 17:00) were fed in the morning, middle and evening. Drink water while observing the cows' feeding and rumination.

Abstract

The invention provides a novel concentrated feed for raising milk nutritional value and the preparation method thereof. DDGS corn dry lees, soluble substances of the DDGS corn dry lees, rumen-bypass amino acid, mineral elements and vitamins are mixed together to produce the concentrated feed. By the adoption of the feed provided by the invention, the milk production of a cow can be increased by 7.23%, namely from 26.30kg to 28.2kg; the content of milk protein in milk can be raised by 9.75%, namely from 3.18% to 3.49%; the milk fat percentage is increased by 3.08%, namely from 3.58% to 3.69%; the content of conjugated linoleic acid (CLA) is increased by 121.45%, namely from 6.33% to 12.91%; the content of protein in discharged manure is decreased by 19.90%, namely from 15.18% to 12.16%; and the feed cost is reduced.

Description

technical field [0001] The invention relates to the field of animal feed, in particular to a method for preparing concentrated feed for dairy cows by using DDGS, which is corn distiller's grains and its soluble matter, which is a protein material replacing soybean meal, and adding rumen-passed amino acids. Background technique [0002] DDGS (Distillers Dried Grains with Soluble, corn distiller's grains and its solubles) is the product of drying the residue obtained after corn is saccharified, fermented, and distilled to remove alcohol in the process of alcohol production. Nutrient ingredients and active factors are high-protein, high-nutrition high-quality protein feed raw materials. According to the data, the rumen passing protein (RUP) content of bean cake and DDGS are 26.5% and 46.5% respectively, indicating that DDGS can provide more RUP than bean cake to ensure the needs of high-yielding dairy cows. For dairy cows, DDGS is not only a high-quality source of RUP, but the...
