Study On The Reproductive Performance Of Sows And The Survival Rate Of Suckling Piglets With L-carnitine Nutrient Solution

For a pig farm,the effective way to realize profit is to improve the reproductive performance of sows and the survival rate of suckling piglets.After a long time of investigation and Research on the pig farm,it is found that the reproductive performance of sows is affected by farrowing performance of pregnant sows,sow delivery process,postpartum recovery,oestrus and mating conditions after weaning;the survival rate of suckling piglets is also related to the health status and self-immunity of sow.L-Carnitine at a certain concentration can significantly increase the number of blastocysts and reduce the number of blastocyst cell death,significantly improve the maturation rate and cleavage rate of oocytes,and then improve the implantation ability of fertilized eggs and improve the survival rate of embryos.L-Carnitine can increase the survival rate and weaning weight of lactating piglets,and reduce the number of piglet deaths during lactation.L-Carnitine can increase the survival rate of weaned piglets.However,there are few studies on whether L-carnitine nutrient solution has the same effect.In view of the above problems,this paper mainly explores the effects of L-Carnitine nutrient solution on reproductive performance of sows(YL)and survival rate of lactating piglets(DYL).The main results of this paper are as follows:(1)The effect of L-Carnitine nutrition solution on the reproductive performance of sows showed that the first was the effect on the farrowing performance of early pregnant sows,40 m L of L-Carnitine nutrient solution was added in the first trimester of pregnancy can effectively improve the farrowing performance of early pregnant sows;the second was in the aspect of sows’ delivery,30 m L of L-Carnitine nutrient solution is fed in the morning of the day when sows are expected to be delivered,and the one that is not delivered on the day of the expected delivery continues to be added L-Carnitine nutrient solution to the delivery,which has a certain effect on sows’ delivery,it can significantly shorten the birth process of sows and promote delivery;the third was in the aspect of estrus and breeding after sows are weaned,30 m L of nutrient solution is added before sows’ delivery,which is helpful to sows normal oestrus and improved mating rate after weaning.(2)The effect of L-Carnitine nutrition solution on suckling piglets showed the results as follows.The first was that the effect of L-Carnitine nutrition solution on the survival rate and growth of suckling piglets was studied,the results showed that: 1 m L or 2 m L of L-Carnitine nutrition solution could effectively improve the survival rate.The second was the effect on the growth of healthy and weak infants during lactation and the survival rate after weaning,adding 2 m L L-Carnitine nutrition solution can improve the growth rate of healthy and weak infants during lactation and the survival rate after weaning.
