Problems solved by technology

However, these drugs are expensive, and the use of warming-type premixes in summer will only be counterproductive, aggravating the heat stress response of sows, and not conducive to improving the estrus rate of sows in summer
[0006] In addition, the feeds in patents CN106107103A, CN105248376A, CN104839479A, and CN104171494A all have a certain effect on improving the estrus rate or littering ability of sows to varying degrees, but they are not used for summer, and summer heat stress and inflammation are not considered.

Abstract

The invention discloses a mixed feed for improving the post-weaning estrus rate of sows in summer. Every 1000 kg of the mixed feed comprises 600-680 kg of corn, 30-70 kg of soybean meal, 40-60 kg of fermented soybean meal, 80-120 kg of expanded soybean, 55-80 kg of corn germ meal, 40-55 kg of apple pomace, 10-13 kg of stone flour, 10-13 kg of calcium hydrogen phosphate, 2-3 kg of lysine, 0.2-0.4 kg of methionine, 0.8-1.0 kg of threonine, 1.7-2.0 kg of tryptophan, 0.2-0.4 kg of chitosan oligosaccharides, 0.4-0.7 kg of plant extract, 0.4-0.6 kg of a mildew inhibitor and 8-10 kg of a premix. Themixed feed is applied in a period from seven days before weaning of the sows in summer to estrus, can effectively increase the feed intake of the sows, reduce the heat stress reaction and inflammationproblems of the sows and improve the post-weaning estrus rate of sows in summer, and is of great significance to actual production.

Description

technical field [0001] The invention belongs to the technical field of feed, and in particular relates to a compound feed for improving the estrus rate of summer sows after weaning and a feeding method thereof. Background technique [0002] For large-scale pig breeding, the estrus rate of sows after weaning is directly related to the benefits of the entire farm, and in summer, the estrus rate of sows after weaning decreases significantly and is common, seriously affecting the production efficiency of pig farms . [0003] In summer, due to the high ambient temperature, sows will have obvious heat stress, which is mainly manifested in some situations such as delayed estrus or no estrus. The specific reason is that the temperature rises in summer, the feed intake of sows decreases, and the effective energy intake decreases, resulting in dysfunction of the normal hormone secretion system, which eventually causes the estrus rate of sows to decrease. At the same time, the high t...
