Lactating sow compound feed capable of relieving astriction under sow heat stress condition

Abstract

The invention discloses a lactating sow compound feed capable of relieving astriction under the sow heat stress condition. The lactating sow compound feed is prepared from the raw materials in ration:corn, 46% soybean meal, soybean hull, wheat flour, soybean oil, complex vitamin, mineral elements, probiotics, phytase, beta-glucanase, xylanase, 98% L-lysine hydrochloride, 98% L-threonine, 99% DL-methionine, tryptophane, valine, 60% choline chloride, table salt, sodium bicarbonate, calcium carbonate, calcium monohydrogenphosphate, glucose and fish meal. A high-energy high-protein daily ration design idea is utilized, excellent protein raw materials are utilized, an ionic equilibrium technology is utilized, and the soybean hull is utilized in a large proportion; compared with traditional daily ration, the lactating sow compound feed can remarkably improve feed intake and dietary fiber intake of sows in a lactation period and effectively relieves astriction situation; sow backfat loss isreduced, weaning weights of piglets and utilization periods of the sows are indirectly improved.

Description

technical field [0001] The invention relates to the field of feed for lactating sows, in particular to a compound feed for lactating sows that relieves constipation in sows under heat stress. Background technique [0002] In recent years, the phenomenon of constipation in lactating sows is very common, and it will be more frequent in summer heat stress. The main clinical symptoms are: difficulty in defecation, dry stool, decreased defecation frequency, loss of energy and appetite. After constipation occurs in sows, the toxins produced by abnormal fermentation in the intestines are absorbed by the body, often causing a series of serious diseases in sows. In the high temperature environment of the hot season, the feces accumulated in the intestines of constipated sows ferment abnormally to produce heat, which leads to an increase in the body temperature of the sows. Lactation, resulting in stunted piglet growth and reduced production performance. In intensive farms, the inci...
