3.Test procedure
(1)Randomly selected 141 multiparous sows(Breeding time is similar),Use completely randomized design,Divided into two processing groups,they are group A with 500g Chang yishu (add in feed mill)A,group B with nothing add,deal with 70 replicates per group,one sow per replicate.
(2)Test period:Prenatal 28 days to sow farrowing,
(3)Test start,Feed the sow with the encyesis feed added Chang Yishu in group A(Daily 3kg/ head),Feed the sow with the encyesis feed without additives in group B(Daily 3kg/ head)
(4)The determination index of the test:see attachment
