Some production traits of indigenous Hair goats bred under extensive conditions in Turkey. 2nd communication: viability and growth performances of kids

Abstract

Abstract. In this study, it was studied that viability in preweaning period and growth performance in the period from birth to 8 months of age of Hair kids (Anatolian Black Goat). A total data of 439 kids in 2003 and 2004 years were used in the study. Survival rates of kids at 1st, 2nd and 3rd months were 98.86 %, 96.81 % and 95.44 %, respectively. The effects of year, farm and age of dam on this trait were statistically insignificant, although the effect of birth type on only the survival rate at 3rd month was significant (p<0.05). The body weights of kids at birth, 1st, 2nd, 3rd, 4th, 5th, 6th, 7th and 8th months were 2.19 kg, 6.19 kg, 9.70 kg, 13.08 kg, 16.31 kg, 18.77 kg, 20.25 kg, 25.38 kg and 23.32 kg, respectively. The effects of sex and age of dam on body weights in all growth periods, the effect of year on weights in growth periods except for 7th and 8th months, the effect of farm on weights in growth periods except for 6th and 8th months and the effect of birth type on birth weight and weights at 4th and 5th months were statistically significant (p<0.05). In the result of this study, it was determined that Hair kids reared under extensive conditions had high performance especially in terms of viability.
