Abstract

The invention relates to daily ration for milking cows producing high-conjugated linoleic acid (CLA) milk, which comprises the following components in percentage by weight of dry matter: 23.40 percent of green hay, 20.45 percent of corn silage, 30.14 percent of corn, 5.00 percent of wheat bran, 4.70 percent of soybean meal, 6.69 percent of cotton seed meal, 4.18 percent of corn vinasse and soluble substance, 0.90 percent of sesame meal, 1.11 percent of calcium hydrophosphate, 0.84 percent of calcium carbonate, 1.00 percent of sodium bicarbonate, 0.39 percent of magnesium oxide, 0.50 percent of table salt, 0.40 percent of CLA calcium salt, 0.20 percent of additive premixing material and 0.10 percent of common mildewproof agent. Compared with an oil fat or pasture supplementing and feeding method, the daily ration can improve the c9,t11-CLA content in milk by more than 100 percent; and compared with a single CLA calcium salt adding method, the daily ration can improve the c9,t11-CLA content in the milk by more than 30 percent.

Description

technical field [0001] The invention relates to the technical field of animal breeding, in particular to the field of dairy cow breeding, in particular to a dairy cow ration for producing high-conjugated linoleic yoghurt. Background technique [0002] With the continuous deepening of people's understanding of the physiological functions of conjugated linoleic acid (CLA), increasing the content of CLA in ruminant food has become a hot spot in animal nutrition research at home and abroad in recent years. CLA in milk has a variety of biological activities. It is a mixture of geometric isomers of linoleic acid with conjugated double bonds. Among them, c9, t11-CLA has anti-atherosclerosis and anti-cancer activities, and accounts for The vast majority of CLA. Milk is the most abundant natural source of c9,t11-CLA, but the content of c9,t11-CLA in milk is low. Therefore, increasing the content of c9,t11-CLA in milk is an important aspect to improve the quality and nutritional val...
