Soybean meal-free and corn-free concentrate supplement for milking cows

Abstract

A soybean meal-free and corn-free concentrate supplement for milking cows comprises the following components by mass: 10-20% of dephenolized cottonseed protein, 35-45% of rice bran, 30-40% of DDGS (distillers dried grains with soluble), 1% of a premixture, 1-2% of sodium bicarbonate, 1-1.5% of calcium powder, 1-2% of salt, 0.1-0.8% of yeast, 0.5-1% of rumen protected fat and 0.6-1.2% of magnesium oxide. The soybean meal-free and corn-free concentrate supplement is prepared according to the following method: the raw materials are uniformly mixed until 99% of the raw materials pass through a 2.8mm woven screen, the raw materials pass through a 1.4mm woven screen, and when matters on the 1.4mm woven screen are less than 20%, the soybean meal-free and corn-free concentrate supplement is obtained. Corn raw grain are no longer used in the soybean meal-free and corn-free concentrate supplement, a corn deep processing by-product is used, the contradiction that human and animals contend for grains is alleviated, the feed cost of dairy farmers is reduced, banned additives are not used and the safety of raw milk can be ensured.

Description

technical field [0001] The present invention belongs to animal nutrition and animal husbandry. Background technique [0002] my country is a big dairy farming country, and its annual milk production ranks among the top in the world. In 2011, my country's milk production reached 20.6 million tons. According to the above classic formula and the current feed-to-milk ratio of dairy cows in my country at 1:2.3, my country's dairy cows consume 1.79 million tons of soybean meal and 4.48 million tons of corn every year. my country is a country seriously short of food resources and protein resources, and the contradiction between humans and animals competing for food has become increasingly prominent. It is necessary to import a large amount of corn and expensive protein raw materials (soybean meal or soybeans, etc.) from abroad every year to maintain domestic breeding. Cheap protein raw material resources and corn substitute raw materials have not been well utilized due to reasons s...

Problems solved by technology

my country is a country seriously short of food resources and protein resources, and the contradiction between humans and animals competing for food has become increasingly prominent. It is necessary to import a large amount of corn and expensive protein raw materials (soybean meal or soybeans, etc.) from abroad every year to maintain domestic breeding. Cheap protein raw material resources and corn substitute raw materials have not been well utilized due to reasons such as craftsmanship, technology and breeding habits
