“…Sire had highly significant effect (P≤0.01) on preand postweaning growth efficiencies in Sirohi goats under field condition. Similar results were found by in Sirohi goats [3] and in Pantja goats [5] for GE (0-3M).…”

“…This might be due to effect of dam's milk during suckling stage which serves as a complete nutritious food for kid. The finding during pre-weaning period was in close agreement as 4.26±0.16 kg/kg in Sirohi goats [3] , 3.98±0.08 kg/kg in Pantja goats [5] . However, lower estimates were also reported in Chegu kids as 2.35±0.04 kg/kg [8] , 3.1967±0.10 kg/kg [9] and 3.11±0.08 kg/kg in Tellicherry goats [10] , 2.30±0.03 kg/kg in Black Bengal goats [11] and 3.71 kg/kg in Raieni Cashmere goats [12] which might be due to breed difference.…”

“…Another reason may be use of initial body weight as denominator in calculation of GE which is usually lower in multiple than single for same age group. Same findings were noted in Sirohi goats [3] , in Pantja goats [5] and in Raieni cashmere goats [12] . However, non-significant effect of type of birth was also reported in Tellicherry goats [9,10] as well as in Black Bengal goats [11] .…”

“…The results were in concordance with Chegu kids [8] , Sirohi goats [3] and Tellicherry goats [10] . However, non-significant effect of season on 0-3M growth efficiency was also reported in Tellicherry goats [9] , in Black Bengal kids [11] and in Pantja goats [5] which might be due to difference in population and environmental conditions.…”

A study was conducted to estimate the pre-and post-weaning growth efficiency (GE) in 6748 Sirohi goats born during 2005 to 2017 under field conditions. The overall least-squares mean for pre-weaning (0-3M) and post-weaning (3-12M) growth efficiencies were 4.31±0.09 and 1.10±0.031 Kg per kg, respectively. Sire, type of birth, sex of kid and cluster had highly significant (P≤0.01) effect on both pre and post-weaning relative growth efficiencies whereas year of birth, season of birth and parity had highly significant effect (P≤0.01) only on pre-weaning growth efficiency. Heritability estimates for pre-and post-weaning growth efficiencies were 0.53±0.06 and 0.44±0.06, respectively. Genetic and phenotypic correlation between two traits was negative.

The present study was conducted to assess the effect of non-genetic factors on relative growth rate of Sonadi sheep of different age groups. In this study data on 1396 Sonadi sheep maintained over the period of 2012-2019 under the Mega Sheep Seed Project, College of Veterinary and animal Science, Navania, Vallabhnagar, Rajasthan were analysed to assess the effect of non-genetic factors (year of birth, season of birth, sex, type of lamb) on relative growth rate viz. 0-3, 3-6, 6-9 and 9-12 months age groups. The overall least-squares mean along with standard error for RGR1 (0-3M), RGR2 (3-6M), RGR3 (6-9M) and RGR4 (9-12M) were 1.32±0.03, 0.42±0.02, 0.226±0.19 and 0.277±0.02 Percent per day, respectively. Year of birth had highly significant (P≤0.01) for RGR1, RGR2 and RGR4 group while significant (P≤0.05) effect on RGR3 group. Effect of season of birth on relative growth rate was also highly significant (P≤0.01) for RGR1 and RGR2 group while significant for RGR3 and RGR4 groups. Sex of lamb showed significant (P≤0.05) effect on RGR1 and RGR2 while non-significant on rest of the groups (RGR3, RGR4) whereas effect of type of birth on relative growth rate was found to be non-significant on all groups. The assessment of non-genetic factors plays an important role to formulate effective breeding programme for improvement of growth performance.
