Effects of Parity of Dam and Breeding Date on the Litter Size of Inner Mongolia White Cashmere Goats

The article through the analysis and research to the effects of parity of dam and breeding date on the litter size of Inner Mongolia White cashmere goats,determine the optimal mating time of Inner Mongolia White cashmere goats,in order to improve the efficiency of reproductive.Data used were 1998 to 2013 reproductive performance records collected from the Arbas stock farm in Inner Mongolia,China.The GLM procedure of SAS 9.0 software was used to determine the significant effect of the parity of dam and breeding date,the results showed that the parity of dam and breeding date had significant effect on litter size (P< 0.01).Litter size was the lowest in 1st parity does (1.37),the significantly increase in litter size with advance in parity and decline after six parity;Mating cycles for September 29th to October 16th had the highest litter size (1.76),and the estrous months and estrus peak time mainly concentrated in October,so this stage in production could be used as breeding period of Inner Mongolia White cashmere goats.
