The autochthonous goat Arbia breed is the most widespread in Algeria, however, little work has been done to evaluate its performance and improve its production. The objective of this study was to evaluate the pre-weaning growth performance of Arbia breed kids and determine the factors that can influence it. The performance control was performed on 120 kids by determining the weights at typical ages and average daily gain (ADG). The main factors studied were birth weight, litter size, and kid sex. The results obtained showed that kids weighed 2.29kg at birth, 4.87kg at 10 days, 6.64kg at 20 days, 8.69kg at 30 days, 11.08kg at 60 days, and 14.01kg at 90 days. The average daily gain rate was 257.84 g / day between birth and 10 days, 177.21g / day between 10-20 days, 205.12 g / day between 20-30 days, 79.58 g / day between 30-60 days, and 97.61g / day between 60-90 days. Birth weight was very strongly related to weights at typical ages of (30, 60, 90) days. Litter size had a very significant effect on birth weight, weight at 90 days, and on the average daily gain between 60-90 days (P˂0.05). Sex showed a significant influence on birth weight, and weights at typical ages of 30 and 90j, as well as on the average daily gain between 60-90 days (P˃0.05). It is necessary to set up programs to characterize and improve the performance of Algerian goat populations in order to give this species the place it deserves in Algerian livestock farming.
