Sow feed for improving litter birth weight and uniformity of sows and preparation method of sow feed

Abstract

The invention discloses a sow feed for improving litter birth weight and uniformity of sows and a preparation method of the sow feed. The sow feed is prepared from the following raw materials: maize, bean pulp, wheat bran, fish meal, mountain flour, calcium hydrogen phosphate, sodium chloride, lysine hydrochloride, L-threonine, L-arginine, N-carbamyl-L-glutamic acid, choline chloride, L-glutamine, multi-vitamin, complex trace elements and a traditional Chinese medicine mixture, wherein the traditional Chinese medicine mixture comprises the middle part of radix angelicae sinensis, wine-fried radix paeoniae alba, ligusticum wallichii, milkvetch root, radix glycyrrhizae preparata, semen cuscutae, bulbus fritillariae cirrhosae, cortex magnoliae officinalis, fructus aurantii, Chinese galangal rhizome, herba schizonepetae, vinegar-fried folium artemisiae argyi and ginger. The sow feed disclosed by the invention is capable of effectively improving the birth weight of piglets, and reducing variable coefficients of birth weight of the piglets in a nest.

Description

technical field

[0001] The invention relates to the field of animal husbandry, in particular to a sow feed for improving the birth weight and uniformity of a sow litter and a preparation method thereof. Background technique

[0002] The birth weight of piglets has an important impact on the survival rate and growth rate of piglets in the later stage. The lower the birth weight, the slower the growth rate of piglets, the lower the immunity, and the higher the mortality rate. At the same time, litter uniformity is also a very important economic indicator, because it is also closely related to the level of piglet mortality before weaning. If the birth weight of piglets in the same litter varies greatly, the low-weight piglets are at a disadvantage in the competition for teats, and the intake of colostrum and regular milk is low, which leads to malnutrition and low immunity; at the same time, the low-weight piglets have physiological energy. With insufficient reserves, the abil...
