“…Season of birth, parity and type of birth had no significant effect on any of the reproduction traits in the present study with Raighar goats. Similar finding was observed for season of birth by Paul et al [10] for weight and age at sexual maturity in Black Bengal goats. However, the flock size showed significant effect on all the reproductive parameters.…”

“…Weight at sexual maturity: Average weight at sexual maturity in the present study was 13.92±0.16 kg. Lower estimate was reported by Bariha et al [4] and Paul et al [10]. However, higher estimate was reported by Rao et al [5] in Ganjam goats and Yadav and Khada (2009) [11] in non-descript goats of Rajasthan.…”

“…This finding also supported by the finding of Otuma (2004Otuma ( , 2006 for pure West African Dwarf goats strains of Savannah eco-zone of Nigeria that varied in weights along the season of rearing. Thus, higher LWB for the does conceived during rainy season might be due to the availability of high lustrous and nutritious forage/fodder during gestation and subsequently kidded during late winter or early spring season compared to other seasons of conception and kidding as reported by Paul et al (2014), Journal & North (2013), Nikhiala (2013) and Amoah et al (1996). This reflected that natural grazing supplied enough nutrients to the does to meet the requirements for conception and kidding in gave birth to heavier litters during parturition as suggested by Nikhiala (2013).…”

Accurate estimates of genetic parameters are important for genetic improvement in Khari goats. In this regard, altogether 1005 adult does of Khari goat in Deurali VDC, Nawalparasi were evaluated in terms of litter weight at birth (LWB) and litter weight at weaning (LWW) and their genetic parameters from February, 2012 to January 2015. Least square means (LSM) and standard errors of the mean (SEM) for these traits were determined with respect to some non-genetic factors such as altitude, season of conception, season of kidding, dam’s parity, dam’s size at conception, and birth type. Accordingly, Overall LSM±SE of LWB and LWW in present study were determined 3.97±0.06 and 18.21±0.34 Kgs., respectively. Where, LWB did not differed significantly with altitude and dam’s parity, however, it was significantly influenced (p<0.001) by the season of conception, season of kidding, dam’s size at conception, and birth type. Similarly, LWW was significantly varied with respect to altitude (p<0.01), season of conception (<0.001), season of kidding (<0.05), dam’s parity (<0.001), dam’s size at conception (<0.001), and birth type (<0.001). Moderately high heritability estimates of LWB (0.52±0.16) and LWW (0.56±0.17) indicated that these traits were under the strong influence of additive genes and selection based the superiority of individual doe would be appropriate for successful genetic improvement. Highly significant positive genetic (rA=0.95) and phenotypic correlation (rP=0.91) between LWB and LWW suggested that selection for any of these trait would result in considerable positive change in other trait. More specifically, LWB can be used as a guide to select replacement does targeting to increased LWW within the herd.

“…Non-significant effect of season of birth was observed on body weight at 6 months of age (Table 2), which is in agreement with the observations of Singh (1991) in Assam Local goats. However, significant effect was reported by Paul et al (2014) in Black Bengal goats. Differences in the body weight at 9 and 12 months of age due to season of birth were found to be significant (P<0.05) in the present study (Table 2), which are supported by the findings of Paul et al (2014) in Black Bengal goats.…”

“…However, significant effect was reported by Paul et al (2014) in Black Bengal goats. Differences in the body weight at 9 and 12 months of age due to season of birth were found to be significant (P<0.05) in the present study (Table 2), which are supported by the findings of Paul et al (2014) in Black Bengal goats. The higher body weight at 9 and 12 months of age for the goats kidded during pre-monsoon season might be due to exposure to better environmental conditions in terms of feeds, green fodder, low heat stress and other management practices.…”

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.
