  The study was conducted to evaluate the growth performance of Boer-Central Highland Goats (CHG) cross kids at Sirinka Agriculture Research Center SARC. A total of 510 kids were used for the analysis of least square mean of birth weight, weaning weight, six month weight and yearling weight. The overall least square mean of birth weight, weaning weight, six month weight and yearling weight were 2.68±0.02, 9.82±0.17, 13.54±0.20 and 19.53±0.38 kg, respectively. The body weight gained from birth to weaning, weaning to six month and birth to yearling were 78.67±1.53, 37.27±1.85 and 33.01±0.77 g day–1. Birth type and year of birth of kids have significant effect on birth, weaning, six month and yearling weight. The birth and weaning weight of the present study had have higher than local breed of Abergelle, Central highland goats, Boran Somali and rift valley. When the age advanced to six month and yearling, the weight were comparable to central highland goats and little bit higher than Abergelle and Boran Somali. For future study, it will needs on farm and on station evaluation with better feeding management to see their genetic potential.

  A study was conducted in the sub humid parts of Sekota District, Amhara Regional State, Ethiopia, to evaluate the reproductive performance of Central Highland goat types raised under the traditional management system of farm households. Twenty-two randomly selected flocks were monitored for two years during which reproductive data were collected on 524 does. The mean least squares Age at first kidding, litter size, kidding interval and kidding rate was found to be 407.9 days, 1.16±0.04 kids, 1.46±0.03, and 307.9 days, respectively. Age at first kidding was affected (p<0.01) by season of birth that does born during the hot season had short age at first kidding. Kidding interval was shorter (p<0.01) for does that kidded during cool season and single litter. Litter size was also affected (p<0.01) by parity and season of kidding. Does kidded in the hot season and those with higher parities had larger litter. The effect of type of birth and season of kidding on annual reproductive rate was significant that multiple bearing does and those kidded in the hot season had larger reproductive rate. The effect of season on most of the traits indicates the need for supplementation of does during the dry season when the grazing condition is very poor for better reproductive efficiency.

  The study was conducted at Abergele in the semi arid parts of Sekota district to evaluate growth performance of Abergele goats managed under traditional management systems. Data on growth and growth rates were collected from 724 kids for two years. The least squares mean birth, three months, six months and yearling weight of kids obtained were 1.91±0.04, 6.84±0.19, 9.13±0.31 and 16.42±1.20 kg, respectively. Parity of doe and birth type of kid significantly affected birth weight and three months weight while sex of kid and season of birth of kid affected birth, three months, six months and yearling weight consistently. Kids from first parity does were lighter at birth, three months and six months of age than kids from higher parity does. Twin born kids were lower in weight at birth and three months of ages than their single born counterparts. Female kids and kids born during the dry season had lower weight at all ages considered. The least squares mean pre-weaning and post-weaning growth rates obtained were 53.4±2.30 and 29.3±4.32 g day-1, respectively. Parity of doe, type of birth and season birth of kid affected pre-weaning growth rate. Kids from first parity does, twin born kids and kids born during the dry season had lower growth rate. The significant effect of fixed factors needs to be considered in an effort to improve productivity of goats in the study areas.
