Production performance of Dera Din Panah goat under desert range conditions in Pakistan.
Effects of fodder availability and prolificacy on birth weight, weaning weight, weight at 6 and 9 months age, and pre- and post-weaning growth rates of Dera Din Panah goat were determined. A total of 350 records of Dera Din Panah (DDP) goats maintained at Sheep and Goat Development Centre, Rakh Khairewala, District Layyah, Punjab, Pakistan were analyzed using Harvey's Mixed Model Least Squares and Maximum Likelihood computer program. Fodder availability significantly affected (P < 0.05) the birth weight, weaning weight, and pre-weaning daily gain. The effect of prolificacy on the birth weight, weaning weight, pre-weaning growth rate was significant (P < 0.05). Effects of fodder availability and prolificacy on average daily weight gain during different stages, such as from birth to 3 months of age (GR1), 3 to 6 months of age (GR2), 6 to 9 months of age (GR3), 9 to 12 months of age (GR4), and overall growth rate from birth to 12 months of age (GR5) age were determined.
