A kind of calf fat powder and preparation method thereof

Abstract

The invention belongs to the technical field of feeds, and particularly discloses calf fatty powder and a preparation method thereof. The calf fatty powder mainly comprises the following components in parts by weight: 1.5-4 parts of lauric acid, 5-10 parts of myristic acid, 10-15 parts of palmitic acid, 3-5 parts of stearic acid, 5-10 parts of oleic acid, 3-10 parts of linoleic acid, 2-5 parts of alpha-linolenic acid, and 0.5-2 parts of vitamin C. The calf fatty powder simulates the composition and the proportion of fatty acid of fat in milk, can meet the requirements of calves for various fatty acid, and overcomes the defects that the calves after weaning cannot absorb enough energy, so that the calves suffer from diarrhoea and are high in mortality rate. The calf fatty powder is prepared into solid powder fat products special for calves, the granules are small, the free-running property is good, and the fatty powder is easy to digest and absorb by the calves.

Description

technical field [0001] The invention belongs to the technical field of feed, and in particular relates to calf fat powder and a preparation method thereof. Background technique [0002] Calf breeding is a key link in dairy cow production and the basis for high-yield dairy cows. Early weaning can reduce the cost of calf breeding, promote the growth and development of the digestive system, and benefit the growth of back-up dairy cows and the production performance of adult cows. Due to the weaning stress during weaning, the ration is changed from liquid milk to solid starter, the digestive system is immature, the feed intake decreases, the digestion and utilization rate of the starter is low, the energy supply is insufficient, diarrhea is prone to occur, and growth is affected. [0003] In view of the above problems, the current technical solution is to prepare calf milk replacer. After searching, it is found that the Chinese invention patent application with application publi...

AI Technical Summary

Problems solved by technology

In addition, calf milk replacer or calf feed formulations reported in other patent literature generally mainly add soybean oil, palm oil and cottonseed oil as energy sources, and the fatty acid composition and ratio in milk and the content of triglycerides The location distribution is very different, and it is difficult for calves to digest and utilize, which cannot meet the calf's energy demand, and even cause diarrhea, which affects the growth and development of calves

Because about 50% of the energy obtained by calves from breast milk comes from milk fat, the digestibility of fat in breast milk is as high as 95% to 98%. From the perspective of fatty acid composition, palmitic acid is the main saturated fatty acid, and it is mainly distributed in the sn-2 position In addition, the absorption in the small intestine is very high, and the palmitic acid of exogenous fat is mainly distributed on the sn-1 and sn-3 positions, not only the absorption rate is low, but the free palmitic acid is very easy to undergo saponification reaction with metal ions in the intestine, forming Insoluble soap salts, causing double loss of mineral ions and energy
