Vitamin premixed feed for milking sow

Abstract

The invention discloses vitamin premixed feed for a milking sow. The vitamin premixed feed for the milking sow is composed of vitamin A, vitamin D3, 25-hydroxyl vitamin D3, vitamin E, vitamin K3, vitamin B1, vitamin B2, vitamin B6, vitamin B12, nicotinamide, D-pantothenic acid, folic acid, D-vitamin, vitamin C, carotene, antioxidant and rice hull powder. The vitamin premixed feed for the milking sow has the advantages that the special vitamin nutritional requirement of the milking sow can be fully met, the health level of the milking sow and suckling pigs can be improved, development of mammary glands of the milking sow is improved, the milk yield of the milking sow and the weaning weight of a suckling piglet can be obviously increased, the weaning stress of the suckling pigs is alleviated, and growth and development of weaned piglets are accelerated.

Description

technical field [0001] The invention relates to the field of premixed feed, in particular to vitamin premixed feed for lactating sows. Background technique [0002] The core nutritional components of compound feed for animals are usually composed of various trace elements, vitamins and feed additives, usually called additive premixed feeds, including compound premixed feeds, trace element premixed feeds, vitamin premixed feeds, traditional nursing mothers The premixed feed for pigs is usually a compound premixed feed, which is a mixture of trace elements, vitamins and feed additives. Not only does it not consider the chemical reaction between the trace elements and vitamins in the compound premixed feed, which will reduce the product effect. It also does not consider the different nutritional needs of lactating sows. The quality of lactating sows determines the survival rate and growth rate of piglets. Therefore, the nutrition of lactating sows is particularly important. At...

[0002] The core nutritional components of compound feed for animals are usually composed of various trace elements, vitamins and feed additives, usually called additive premix feed, including compound premix feed, Trace element premixed feed, vitamin premixed feed, the traditional premixed feed for lactating sows is usually a compound premixed feed, which mixes trace elements, vitamins and feed additives together, not only does not consider the trace elements in the compound premixed feed There is a chemical reaction between vitamins and vitamins, which reduces the effect of the product, and does not consider the different nutritional needs of lactating sows. The quality of lactating sows determines the survival rate and growth rate of piglets, so the nutrition of lactating sows is particularly important. Importantly, at present, most pig farms are still feeding suckling sows with conventional compound premixed feed, which leads to poor development of mammary glands of lactating sows, which directly leads to nutritional deficiencies, growth retardation, and increased mortality of suckling pigs, affecting milk production. Weaning weight of pigs aggravates weaning stress and affects subsequent growth and development of piglets
