Embodiment 3
[0034] Example 3 Effect Test on Estrus and Ovulation Number of Multiparous Sows
[0035] In order to verify the feeding effect of the present invention on the estrus interval, estrus symptoms and litter size of multiparous sows, the present invention carried out a feeding test in Taicang breeding pig farm in November 2015. Using a single-factor comparative design, a total of 36 healthy multiparous sows were selected and randomly divided into an experimental group and a control group, with 18 pigs in each group and one repetition per pig. The sows in the control group were fed Anyou lactating sow feed after weaning, and the sows in the test group were in the stage of weaning to estrus, and the inventive product described in Example 1 was sprinkled 300g / d / The feeding amount and other feeding management methods of the two groups were exactly the same. Among them, the estrus interval, estrus rate, mating farrowing rate and litter size are the main indicators, and the influence o...
