Abstract EN

This study was conducted in the animal from belanged to the college of Agriculture/University of Qadisiyah during the period from 18/11/2014 to 18/06/2015 using 57 goat kids divided in to four genetic groups (breed) the first group was (Afghan male × Afghan female) consists of 13 Billy gouts belonged to 9 female mother.

The second group was (CY male × CY female) and consists of 12 Billy goats belonged to 8 female mother.

Third group was (Local male × Local female) and consists of 16 Billy goats belonged to 9 female mother.

Forth group was (Afghan male × Local female) and consists of 16 Billy goats belonged to 10 female mother.

The aim of the present study was to determine the effect of genetic group (breed) and some of non- genetic factors that represented by sex of the kids type of birth, mother age at birth In goat kids weight at birth and weaning, average increase of daily and total weight.

Average goats kids weights at birth and weaning 3.28, 12.95 kg respectably , and the genetic group had highly sign.

ficont (P <0.01), in these weights in Afghan group outperformed the rest groups at birth and weaning, The kids sex did not have significant effect in goat kids weight at birth but it had highly significant impact on the weight at weaning as the goats males outperformed on females on the group, as well as the type of birth had a highly significant effect in goat kids weight at birth and weaning by showing the superiority of the single goats group on twin while.

The mother age did not have a significant effect on the goats weights, the overall average daily and total weight gain for goat kids from birth until weaning ware 107 g and 9.67 kg respectively.

Genetic Group was significantly affected (P <0.01) in these characters, a the Afghan goats group showed significant superiority in the increase of daily and total weight compared with other groups, kid sex and type of birth had was highly significant impact high (P <0.01) in the average daily and total weight as showed suporioity of males goats group on the females and the individual on the twin.

However, mother age had no significant effect on it.
