Feed for sows during gestation

Abstract

The invention discloses feed for sows during gestation. The feed is prepared from the following raw materials in percentage by mass: 58% of yellow corn, 4% of alfalfa, 4% of soybeans, 8% of bean pulp, 2% of largeanther senna, 5% of sweet potatoes, 10% of silkworm chrysalis, 3.5% of fish meal, 4% of meat and bone meal, 0.5% of egg-shell powder, 0.3% of salt, 0.3% of calcium carbonate, 0.1% of calcium hydrogen phosphate, 0.2% of vitamin additives, 0.05% of ferrous sulfate, 0.02% of zinc sulfate, 0.01% of lysine, 0.01% of methionine and 0.01% of oxytetracycline. The feed disclosed by the invention is relatively high in energy and protein level, relatively balanced in nutrient, and capable of meeting both the breeding needs and the pig growth needs. The oxytetracycline is used in the formula, so that the immunity of the sows can be improved, the breeding rate can be guaranteed, and the yield-increasing effect can be achieved.

Description

technical field

[0001] The invention relates to animal feed, in particular to a feed for sows. Background technique

[0002] The nutritional needs of sows vary greatly during pregnancy, and the formula is designed to meet the nutritional needs of different reproductive performances. During pregnancy, feed quality has a decisive impact on reproductive performance. Insufficient vitamins are prone to stillbirth and embryo reabsorption and mummification. Insufficient mineral elements are prone to abnormal embryo development, such as iodine deficiency in sow feed, piglets born with skin Hairless. Energy and protein nutrition are not suitable, which affects the survival rate of embryos. Therefore, it is very necessary to feed pregnant sows with nutritious and comprehensive feeds, but there are too few special feed varieties on the market at present, and the development of special feeds for sows during pregnancy has market value.
