The invention provides a breeding method for improving the production performance of pregnant sows, and the breeding method comprises the following steps: (1) from the 25th-35th day of pregnancy to the 55th-65th day of pregnancy of the sows, adding a first nutritional supplement into a sow feed; (2) from the 55th-65th day of pregnancy of the sows to the 85th-95th day of pregnancy of the sows, adding a second nutritional supplement into the feed of the sows; and (3) adding a third nutritional supplement into the sow feed from the 85th-95th day of pregnancy to delivery of the sows. The breeding method provided by the invention can fully meet the nutritional requirements of the pig fetuses, promote the growth and development of the pig fetuses, avoid intrauterine development retardation, relieve oxidative stress of the sows, shorten the birth process, reduce postpartum inflammation of the sows, promote rapid recovery of the sows, reduce the number of weak piglets, improve the birth weight of the piglets, and further improve the survival rate and health state of the piglets.

The application relates to application of an olive extract in preparation of a daily ration additive for improving reproduction performance of mammals, wherein 0.05 wt% of the olive extract is added in the daily ration of a pregnant mammal, so as to improve embryo survival rate, live birth number, initial birth litter weight and lactation capacity of the mammal; the application explicitly shows the influence of the olive extract on embryo development and lactation capacity of the mammal, and provides a new technical approach for high-value development of olive resources and nutrition regulation of the mother and the child.

The invention discloses a concentrate supplement for improving the lambing rate of Inner Mongolia cashmere goats, and a preparation method, a feeding method and an application thereof. The concentrate supplement belongs to a concentrate supplement for goats. In order to solve the problem of improving the lambing rate and cashmere production of Inner Mongolia cashmere goats, the concentrate supplement comprises 30-40 parts of corn, 15-25 parts of puffed corn husks, 3-8 parts of soybean meal, 4-8 parts of cottonseed meal, 3-8 parts of wormwood meal, 8-15 parts of DDGS, 2-6 parts of protein powder, 2-4 parts of palmitic acid fatty acid calcium, 0.3-0.7 parts of corn oil, 3-5 parts of wormwood seed oil, 0.01-0.05 parts of a complex enzyme preparation, 0.8-1.2 parts of calcium hydrogen phosphate, 1.5-2.5 parts of stone powder, 0.7-1.1 parts of sodium chloride, 0.8-1.1 parts of sodium bicarbonate and 1.0-2.0 parts of a premix. The effect is that the lambing rate and cashmere production of Inner Mongolia cashmere goats can be improved.

The invention discloses application of sodium butyrate in improving quality of queen bees, and belongs to the technical field of biology and agriculture. According to the method, starting from the direct environment of queen bee development, namely the feeding group, the intestinal mucosa nutrient sodium butyrate is added into the feed of the bee group, so that the nutrition management of the feeding group is optimized, the nutrition level of the feeding group is improved, and the feed utilization rate of the feeding bee is improved, thereby providing higher-quality nutrient substances for the development of the queen bee; the quantity and quality of royal jelly secreted by feeding bees are increased, so that the purpose of improving the quality of queen bees is achieved. In addition, the sodium butyrate is good in safety when being used for feeding swarms, and does not generate negative effects on the queen cell acceptance rate and the house output rate.
