“…The possible reason for the significant difference between breeds is attributable to breed difference (Hyder et al, 2002), as the Teddy is highly prolific whereas the Beetal is considered medium prolific. Secondly, the parity is known to have positive effects on litter size in goats (Pan et al, 2015). Consistent with the current results, Ahlawat et al (2015a) reported significant effects of breed and parity on litter size in six Indian goat breeds.…”

The genes BMPR1B, GDF9 and BMP15 are oocyte-derived members of the transforming growth factor-β superfamily, which is essential for follicular growth and ovulation. The aim of the current study was to determine the incidence of reported mutations in exon 3 of BMPR1B gene, exon 1 of GDF9 gene, and exon 2 of BMP15 gene and their association with litter size in three parities of Beetal and Teddy goats. Based on the known mutations in these genes, PCR primers were designed to find out the polymorphism through the PCR-RFLP technique in 120 randomly selected animals of the two breeds, which vary in their prolificacy. The current results show that there were significant differences in litter size [1.708 ± 0.060 in Beetal (B) and 2.167 ± 0.056 in Teddy (T) goats] in both breeds. The results of breed x parity interaction showed significant differences in litter size in first [1.158 ± 0.061 (B); 1.861 ± 0.057 (T)], third [2.062 ± 0.078 (B); 2.583 ± 0.073 (T)] and average parity [708 ± 0.060 (B); 2.167 ± 0.056 (T)] in both breeds. All three loci in both breeds were found to be polymorphic and the results of breed x parity x genotype analysis showed that genotypes of all the three genes were significantly associated with litter size in all parities in both breeds. For the BMPR1B gene, heterozygous (CT) animals of Beetal and Teddy goats had the largest litter size in all three parities and the average (parity) litter size, showing the overdominance of the heterozygotes. Similarly, for GDF9 gene, heterozygous animals (AG) had the largest litter size in both breeds. For BMP15 gene homozygous carrier animals (CC) of both breeds had the highest number of kids, followed by the heterozygous (AC) genotypes. The current results show the importance of BMPR1B, GDF9 and BMP15 as the major genes that influence prolificacy in both Beetal and Teddy goats. It is suggested that these polymorphisms can be used as molecular markers to select the prolific animals in these breeds.

“…The overall LSM ± SE for height at withers, heart girth and body length were 41.231 ± 0.121 cm, 43.902 ± 0.120 cm and 46.791 ± 0.112 cm at 6 months; 44.621 ± 0.115 cm, 48.890 ± 0.099 cm and 52.765 ± 0.090 cm at 9 months; and 50.778 ± 0.172 cm, 55.552 ± 0.170 cm and 58.392 ± 0.207 cm at 12 months of age, respectively (Table 3, 5 and 7). These findings were in accordance with the findings of Pan et al (2015) in Black Bengal goats for height at withers and heart girth, and Saikia et al (1985) in Assam Local goats for body length. However, much higher values were recorded in Sirohi goats by Dudhe et al (2015).…”

The present work was conducted to evaluate the performance in respect of post-weaning growth and morphometric traits of Assam Hill goat. Data on 960 animals belonging to 3 populations of Assam Hill goat maintained at three field units viz., Batabari, Nahira and Tetelia under All India Coordinated Research Project on Goat Improvement were utilized. The least-squares means for body weight, height at withers, heart girth and body length were 7.557 ± 0.049 kg, 41.231 ± 0.121 cm, 44.621 ± 0.115 cm and 50.778 ± 0.172 cm at 6 months; 9.934 ± 0.044 kg, 43.902 ± 0.120 cm, 48.890 ± 0.099 cm and 55.552 ± 0.170 cm at 9 months and 12.549 ± 0.046 kg, 46.791 ± 0.112 cm, 52.765 ± 0.090 cm and 58.392 ± 0.207 cm at 12 months of age, respectively. Location had significant effect on body weight and height at withers at all age groups; on heart girth at 6, 9 and 12 months and on body length at 6 and 12 months of age. Season of birth exerted significant effect on body weight at 9 and 12 months; on height at withers at 12 months and on body length at 6, 9 and 12 months of age. Significant effect of sex was observed on body weight at 9 and 12 months, on height at withers at 6, 9 and 12 months and on heart girth and body length at 9 and 12 months of age. The heritability estimates for body weight and body measurements were moderate indicating scope of selection. The phenotypic and genetic correlation among body weights and body measurements at 6, 9 and 12 months of age were positive in direction and high in magnitude.

Aim: This study aimed to determine the genetic and non-genetic factors affecting pre-weaning body weight (BW) and morphometry in Assam Hill goat along with the genetic parameters. Materials and Methods: The detailed information in respect of BW and body measurements of 960 animals at birth and 3 months of age belonging to three different populations of Assam Hill goat maintained at field units, namely, Batabari, Nahira, and Tetelia under "All India Coordinated Research Project on Goat Improvement" were utilized in the present study. The data were analyzed using least squares technique. Results: The least squares means for BW, height at withers (HW), heart girth (HG), and body length (BL) were 1.166±0.008 kg, 26.198±0.070 cm, 26.695±0.096 cm, and 29.482±0.119 cm at birth and 4.590±0.083 kg, 36.850±0.105 cm, 40.741±0.115 cm, and 39.703±0.108 cm at 3 months of age, respectively. Location had a significant effect on BW, HW, and BL at both birth and 3 months and on HG at 3 months of age. Season of birth exerted significant effect only on BL at birth, whereas the significant effect of sex was observed on HG and BL at 3 months of age. The heritability estimates for BW and body measurements were moderate indicating the scope of selection. The phenotypic and genetic correlations among BWs and body measurements at birth and 3 months of age were positive in direction and high in magnitude. Conclusion: On the basis of the present findings, it could be concluded that the weaning weight of kids can be considered for the selection of parent stock to increase productivity and eventually the economic efficiency. Further, animals with higher body measurements at initial phases of growth will perform better with respect to even BW at later stages of growth. Keywords: Assam Hill goat, genetic parameters, morphometric traits, non-genetic factors, pre-weaning growth.
