Forage improving ovulation amount of back-up nonpregnant sow

Abstract

The invention provides forage improving ovulation amount of back-up nonpregnant sows and a manufacturing method thereof. A recipe includes 42 kg of fermented bean dregs, 0.40-0.45 kg of soybean oil, 30-40 kg of corn, 15-18 kg of wheat bran, 8-10 kg of fermented soybean meal, 3-6 kg of premix, 2-4 kg of oil powder, 0.125 kg of baking soda, 0.040 kg of multivitamin, and 0.05 kg of lysine. The materials are sufficiently mixed by stirring to get the finished product. The back-up nonpregnant sows are raised by the forage. The primiparity sows ovulate 19.35 on average, and the multiparity sows ovulate 24.69 on average. Fecundity is significantly improved.

Description

technical field [0001] The invention relates to a feed formula, in particular to a feed formula that uses fermented bean dregs as the main raw material and adds other auxiliary materials therein. Feed formulation to increase ovulation in spare, empty sows. Background technique [0002] Okara contains a lot of useful ingredients for pigs, but it also contains anti-nutritional factors, and the fermentation of okara can effectively decompose harmful components. [0003] In the traditional breeding of back-up and empty sows, in order to increase their ovulation volume, 20 mg of No. 3 to promote ovulation is often injected intramuscularly after the first mating of sows, which can promote ovulation, increase the conception rate and litter size. However, this method of operation is difficult to grasp the exact date of injection, and long-term application of large doses will produce a heterogeneous effect, that is, an obvious inhibitory effect. [0004] The present invention solve...
