A study of some factors affecting fertility, fecundity and twining rate in local and Cyprus goats

Abstract EN

Analysis of 195 records of goats presented in ruminants research station, which belonged to General directorate of Agricultural Research in the 2013 production year.

The records belonged to 59 local goats and 136 cyprus goats.

The age of goats ranged between 2-8 years.

The aim of study to know the effect of some factors affecting fertility, fecundity and twining rate in local and Cyprus goats.

The results showed that the fertility, fecundity and the twining rate were 77.96%, 167.39% and 60.86% in local goats respectively.

While the parameters were 80.14%, 194.44% and 69.72% respectively.

There was no significant difference in fertility rate between different breeds.

While there was a significant difference (P<0.01) in fecundity and in twining rate (P<0.05) for the Cyprus goats as compared with local goats.

There was a high a significant difference (P<0.01) the weight of the mother at the insemination on the three traits.

There was no significant effect of month of insemination on fertility rate, While there was a high significant (P<0.05) in twining rate at the months of insemination.

There was a significant effect (P<0.01) of mother age on all traits understudy
