Abstract :

The objectives of this study were to investigate the possibilities of using kids as breeding goat in the first year of life, determine the fertility, production and growing traits of the kids. Fertility, mating, milk production, live weights and body measurements were determined of Saanen x Hair Goat crossbred (G1) goat and kid groups and the obtained data were compared. In the study, 96 Saanen x Hair Goat crossbred (G1) kids and 24 Saanen x Hair Goat crossbred (G1) goats (2-3 age) were used. While the rate of pregnancy and birth of Saanen x Hair Goat crossbred (G1) goat and kid groups were respectively 95.8%, 92.7% and 87.5%, 76.1%; the rate of single, twin and triplet birth were 28.6%, 68.5%; 42.8%, 23.3% and 19.1%, 2.7%. The kid yields of Saanen x Hair Goat crossbred (G1) goat and kid groups were 171.4% and 123.3%. The live weights and body measurements of the kids on the 30th and 75th day and survival ability on the 30^th, 75^th and 180^th day were similar in the two groups. In spite of a decline has been shown in fertility, live weight, live weight gain, body measurements, viability and milk yield when impaired the goat and kid groups, it is concluded that using kids in breeding in early ages may be more useful economically for breeders in terms of prolonging the lifetime of animals.
