Complete formula feed for adjusting synchronized farrowing of sows in daytime, manufacturing method and application

Abstract

The invention discloses complete formula feed for adjusting synchronized farrowing of sows in daytime, a manufacturing method and application. The complete formula feed is formed by corns, soya bean meal, bran, fish meal, soya bean oil, phosphoric acid, rock flour, salt, zeolite powder, choline chloride, pinto beans, nucleotide, mineral element premix compounds and amino acid premix compounds. The method includes the first step of conducting the smashing process, the second step of conducting the premix compound mixing process, the third step of conducting the modulating and granulating process, the fourth step of conducting the cooling process and the fifth step of packaging. The sows are effectively adjusted to conduct farrowing in daytime, the labor intensity of breeding personnel is lowered, mechanical death of the sows is prevented, and the survival rate of piglets is increased. Effects are obvious, side effects are avoided, simpleness and safety are achieved, the proportion of the sows conducting farrowing in daytime is increased to 80-100 percent, synchronized farrowing of the sows is regulated through nutrients, feed management and nursing of the sows after farrowing are facilitated, the survival rate of newborn piglets is increased by 5-10 percent, the dead born rate of the sows is reduced by 3-10 percent, and the labor cost of a farm is monthly reduced by 3000-6000 yuan per thousand sows due to synchronized farrowing of the sows in daytime.

Description

technical field [0001] The invention belongs to the field of aquaculture, and relates to a full-price compound feed for sows, more particularly to a method for preparing a full-price compound feed for regulating the delivery of sows at the same time during the day, and also relates to a premixed feed for sows Use in feeding. Background technique [0002] Before weaning, the mortality of piglets is about 10-15%. Newborn piglets are prone to premature death within three days after birth, especially within a few hours after being separated from the mother. The stillbirth rate caused by sow dystocia is about 5-10%, which has caused huge losses to the pig farm. Accurate prediction of sow farrowing is an important means to reduce sow postpartum disease and newborn piglet mortality. Especially when the delivery time of sows occurs during the day, it is beneficial for farmers to care for sows with dystocia, monitor the intake of colostrum of piglets, reduce the possibility of pig...

Problems solved by technology

The effect of PGF2-α drugs is relatively moderate, and it is not easy to cause hypoxia in piglets during delivery (Kaeoket P C K. The effect of dose and route of administration of D-cloprostenol and cloprostenol on the parturient response of sows. Thai Journal of Agricultural Science, 2008,41(1-2):19-27), but there are many problems in prostaglandin drugs, which limit their application and promotion

First of all, hormones may cause endocrine disorders in sows and even affect the subsequent reproductive performance; the price of prostaglandins is high, which increases the cost of breeding; it must be administered in strict accordance with the expected date of delivery, 2 days in advance, but hormones have an effect It has the characteristics of quick effect, and the expected date of delivery itself is artificially calculated, so the inaccurate administration time may lead to premature delivery of sows; it must be given by intramuscular injection, and there are nursing problems in intramuscular injection; intramuscular injection requires a lot of labor. Manpower, especially not easy to operate in large pig farms; prostaglandin substances are easily absorbed by the body through the skin, which increases the biosafety risk during operation (Chen Hainan
