The invention discloses a premixed biological feed and a compound feed for a pig at the stage of fattening. The premixed biological feed comprises the following components according to certain percentage: 0.10 percent of
vitamin A, 0.02 percent of
vitamin D, 0.2 percent of
vitamin E, 0.05 percent of
vitamin K3, 0.03 percent of
vitamin B2, 0.01 percent of
vitamin B6, 0.02 percent of
vitamin B12, 0.09 percent of
calcium pantothenate, 0.17 percent of nicotinic acid, 5.00 percent of
choline, 4.5 percent of FeSO4 H2O, 0.5 percent of
antioxidant, 0.8 percent of
copper sulfate, 3.5 percent of monohydrate
zinc sulphate, 0.8 percent of
manganese sulfate, 0.45 percent of
selenium with 1% of
mass concentration, 0.32 percent of
iodine with 1% of
mass concentration, 1 percent of concentrated
enzyme, 10 percent of Chinese herbal
medicine additive, 12 percent of
lysine, 1.5 percent of sweetener, 4 percent of
flavouring agent and 54.94 percent of
zeolite. The compound feed comprises the following components according to certain percentage: 60.17 percent of corn, 20 percent of bean pulp, 12 percent of rice
bran, 5 percent of rice
bran, 0.51 percent of
calcium hydrophosphate, 1.07 percent of mountain flour, 0.25 percent of salt and 1 percent of premixing biological
fodder. The premixed biological feed has
low copper content and contains no
arsenic and
antibiotics, and the compound feed can lead such biomasses as corn,
bran, rice bran and the like to be fully digested and absorbed. The feed utilizing rate is high, the cultivating cost is low, the
disease resisting capability is strong, the meat quality is safe, and the environmental
pollution is low.
