Abstract

The invention relates to the technical field of livestock breeding, in particular to a composite enzyme preparation and a sheep feed containing the composite enzyme preparation. The sheep feed with the added composite enzyme preparation is prepared from 20-30% of corn stalk and / or wheat straw, 30-40% of corn, 6-8% of soybean meal, 8-12% of cottonseed meal, 18-20% of corn germ meal, 0.6-0.8% of bentonite, 0.8% of stone powder, 1.2% of table salt and 1.0% of premix compound, and the premix provides 2500-3500 IU of vitamin A, 2000-2500 IU of vitamin E, 70-80 mg of iron, 40-50 mg of zinc, 5-8 mg of copper, 0.6-1.0 mg of iodine, 20-30 mg of manganese, 0.2-0.3 mg of selenium, 0.2-0.3 mg of cobalt and 0.2-0.4% of the complex enzyme preparation of the invention for per kg of the feed.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of animal husbandry, and in particular relates to a compound enzyme preparation and sheep feed added with the compound enzyme preparation. [0003] Background technique: [0004] The rational and efficient utilization of straw resources is of great significance to national production. It has the characteristics of renewable, wide distribution, large quantity and low pollution, and has become one of the pillar energy sources for sustainable development. According to reports, 14% of the world's energy is produced by crop straw, and straw is the main source of roughage for ruminants, and provides energy for rumen microorganisms and ruminants themselves. Corn and wheat are the main food crops in my country, and straw resources are abundant. According to reports, in 2015, the output of straw resources in my country was about 809 million tons, and the largest output was corn straw, rice straw and wheat stra...
