Embodiment 1

[0029] A multi-functional mixed feed additive that can promote estrus and increase the number of ovulations in sows, consisting of 40% fermented soybean meal, 5% soybean oil, 10% oil powder, 20% glucose and fructose, 0.8% multivitamin, and 1% multivitamin , omega-3 fatty acid 0.4%, kelp powder 10%, carrier 12.8%.

[0030] The fermented soybean meal is prepared according to the method of CN 201410659389.0.

Embodiment 2

[0032] A multi-functional mixed feed additive that can promote estrus and increase ovulation in sows. It consists of 35% fermented soybean meal, 15% oil powder, 25% glucose and fructose, 0.7% multivitamin, 1.1% multivitamin, ω-3 0.5% fatty acid, 8% kelp powder, and 14.7% carrier.

[0033] The fermented soybean meal is prepared according to the method of CN 201410659389.0.

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...

Abstract

The invention provides a multifunctional mixed feed additive capable of promoting sow oestrus and increasing ovulation number. The additive is prepared from, by weight, 30-50% of fermented soybean meal, 0-10% of soybean oil, 5-15% of oil meal, 15-25% of glucose and fructose, 0.6-1.0% of decavitamin, 0.8-1.2% of composite mineral substance, 0.3-0.5% of omega-3 fatty acid, 5-15% of kelp powder and 10-20% of a carrier. The oestrus state of standby and multiparous sows can be improved, nutrient substances capable of promoting development of sow reproductive organs can be supplemented, the internal secretion function is improved, the ovary function is activated to promote oestrus and ovulation; the oestrus interval of the multiparous sows can be shortened, oestrus characters of the sows are prominent, the sow ovulation number is increased to increase the litter size, breeding performance is improved, and reproductive performance of the sows is not damaged.

Description

technical field [0001] The invention relates to the field of feed additives, in particular to a multifunctional mixed feed additive that can promote estrus and increase ovulation number of sows. Background technique [0002] In large-scale pig farms, a large number of gilts and multiparous sows are eliminated every year due to lack of estrus, delayed estrus or low pregnancy rate, which brings huge economic losses to actual production. Excluding the three factors of disease, season and exercise, the main causes of anoestrus or repeated infertility are feeding management, long-term malnutrition or bloated sows, eating moldy feed, improper stocking density, and poor environmental sanitation , Unreasonable factors such as lure with boars, etc., all affect the endocrine of sows, causing physiological disorders, delayed estrus or no estrus. Existing aphrodisiac methods include optimal feeding before mating, more exercise, boar stimulation, use of Chinese and Western medicine or b...
