Problems solved by technology

[0002] The quality of chicken should be grasped from the source. The early growth period of broilers (1-14 days old) is the most critical period of growth. At this stage, the growth metabolism is extremely vigorous, the growth intensity is high, the adaptability to the environment is weak, the stress resistance is poor, and it is easy to During this period, the feed of broilers is very important. Healthy feeding of broilers in the early stage of growth is a solid foundation for rapid growth in the middle and late stages. In the prior art, in order to improve the growth rate of broilers, corresponding additives of various Growth-promoting agents are very common, and it is very common to adopt high-energy methods in the preparation of diets. Astragalus polysaccharides have been verified to have a better promoting effect on the growth performance and organ index of 1-14-day-old broilers. But at present, the extraction rate of astragalus polysaccharide is low, and the corresponding cost of adding it to feed is relatively high, which is not conducive to reducing the cost of breeding

Abstract

The present invention relates to the technical field of domestic poultry feeds and more particularly relates to a feed additive for improving viscera indexes of young chickens at 1-14 days age. The additive is an alfalfa extract. In the alfalfa extract, the content of alfalfa polysaccharide is 50-58% and the total saponin content of alfalfa is 30-32%. It is tested by inventors that the obtained alfalfa extract has relative good promoting effects for the growth performance and viscera indexes of the viscera indexes of the young chickens at 1-14 days age as well, but the cost of the alfalfa is much lower than the cost of radix astragali. Besides, the yield of the alfalfa extract is extremely high, and every 100 g of the alfalfa can be extracted to obtain 8.82-9.05 g of the alfalfa extract.
