Description
Technical Field
The invention belongs to the field of microorganisms, and particularly relates to a feed additive, a feed and a feeding method.
Background
The improvement of the yield and the quality of the pilose antler directly influence the economic benefit of the farm. In the prior art, the antler yield is increased mainly by crossing the sika deer and the red deer, but the quality of the antler is reduced. Other techniques are also used for treating the stags by using hormones, but hormone residues are caused, the quality of the pilose antler is influenced, and the health of the stags is also damaged. The technology for improving the pilose antler by using Chinese herbal medicines is also available, but has high cost and unstable effect and is not easy to widely popularize.
There are many factors that affect the growth of pilose antler, mainly in the aspects of nutrition, environment, management, etc., wherein nutrition is the main factor. The nutrition level of deer is the basis of the growth of the deer antler, and the deer must be provided with complete feed for obtaining high-quality and high-yield deer antler. Malnutrition in the antler growth period, slow growth of the antler, small and thin antler angle and even malnourished traces on the antler body are left. When enough protein feed such as bean cake, bean pulp and the like is required to be supplied, 16-26% of protein feed is added into the concentrate supplement in the early antler growth period of the adult sika deer, the crude protein level reaches 14.5%, 18-28% of protein feed is added into the concentrate supplement in the antler growth period, and the crude protein level reaches 16%, the method is suitable. The ratio of the refined grain to the coarse grain of the feed is 1:1 is preferred. The feed of calcium and phosphorus feed and rose essential oil are ensured in the antler growth period, the calcium and phosphorus feed in the early period meets the supply requirement, and the ossification speed of the antler is slowed in the later period, so that the dosage can be properly reduced.
Scientific experiments and production practices prove that the reasonable use of the feed additive can effectively improve the yield of the pilose antler. The feed additive mainly supplements trace and indispensable nutrient components, such as vitamins, trace elements, amino acids, antibiotics and non-nutritive additives for regulating the digestive metabolism rate of nutrient substances of deer, such as rumensin and the like. The rumensin can reduce protein catabolism in rumen, so that part of nutrients can enter the rear section of digestive tract for digestion and absorption, and the utilization rate of nutrients is improved. Practice shows that the addition of the additive (premix) for deer into the concentrate supplement of deer can improve the yield of the deer antler by 13.49-32.67%.
However, although there are many kinds of animal feed additives on the market, the animal feed additives are rarely used for breeding deer, and the animal feed additives are not ideal in promoting the growth and health of deer and improving the yield and quality of deer antlers. Therefore, there is an urgent need to develop a feed additive which can effectively increase the yield and quality of velvet antler and is safe and free of side effects.
