Husbandry Practices and Phenotypic Characterization of Bidri Goats in Karnataka

Background: The present study is focused on documentation of the husbandry practices and phenotypic characterization of Bidri goats, which is essential in recognition and improvement of this breed. Methods: A total of 20 random flocks in 7 villages were investigated. Data was collected as per the standard format suggested by ICAR-NBAGR (2012) and was statistically analyzed using analysis of variance in R software environment. Result: The average flock size of these goats was 33.43±4.73. The smaller flocks were generally housed in the part of residence, whereas, larger flocks (30-40 goats) were housed separately. Random mating was observed as males and females were grazed and housed together. These goats were predominantly black (73%), but black with white patches on ears, forehead, neck and knees (18%) and black with brown coat color (9%) were also found. The eyelids, muzzle and hooves were generally black in color and few exceptions were also seen. The forehead was straight in most of the goats but it was convex and concave shaped in very few. In these goats, 78 per cent were horned and were generally upwards, backwards, outward and curved, 13 per cent had downwards, backwards, outward and curved horns. Majority of these goats have pendulous ears and very few had horizontal ears. The average age at first estrus, first kidding, weaning age and kidding interval observed were 10.33±0.24, 17.57±0.40, 4-6 and 8.48±0.38 months, respectively. Usually the first kidding was single; twinning and triplet was 40 and 5 per cent of the breedable does, respectively. The mean body weight was 32.88±1.04 kg in bucks and 30.08±0.59 kg in does. Bidri goats are distinct and selective breeding would improvise the economic traits in these goats.

Successive Generations

Silkworms are well-known industrial insects, which produce natural fiber silk. Because of economic importance for silk yarn, an effort to breed new silkworm variety has been made for thousand years. High cocoon yielding due to high resistance, high silk reeling ability and productivity, better silk quality in neatness and lousiness is essential for new silkworm variety to increase silk productivity. Today, several hundred varieties have been bred accordingly various interests and purposes (Kang et al., 2001, 2002). Pupation rate, single cocoon weight, cocoon shell weight and cocoon shell percentage are the main factors affecting the high yielding of cocoon (Kang et al., 2001, 2002). Native silkworm varieties have the low performance and could not be commercially employed. Indigenous strains are valuable genetic resources. They have been affected by natural selection in the successive generations and adapted to indigenous diseases and environmental conditions. Genetic and phenotypic characterization of locally available native silkworm populations provides essential information to make rational decisions for the improvement and development of effective breeding programmes. Hence, the present study was undertaken to identify genetic potential of indigenous silkworm for designing suitable breeding programmes.

SummaryThe study examines phenotypic characterization of Central Highland and Woyto-Guji goat breeds at Meta Robi and Konso districts of Ethiopia. Purposive and random sampling techniques were employed to select sample villages and respondent. For administration of semi-structured questionnaire and phenotypic characterization, a total of 240 households and 601 adult animals, respectively, were selected. The average goat flock size (31.25 ± 22.46) owned per household of Konso was significantly (P< 0.01) higher than Meta Robi (12.73 ± 8). In Konso, natural pasture was the most frequently mentioned feed source during wet season, while hay was the most important feed source during dry season. On the other hand, in Meta Robi, natural pasture was the most frequently mentioned feed source during wet and dry seasons. Coat colour type, horn shape, ear orientation, wattle and beard were found to differ highly significantly (P< 0.001) among the two goat breeds. Goat breed had a significant effect (P< 0.001) on body weight and other body measurements except pelvic width (P> 0.05). The least-square means of body weight, body length, height at wither, chest girth, chest width, ramp length, horn length, ear length and pelvic width of Central Highland female goats were 29.5 ± 0.2 kg, 62.2 ± 0.2 cm, 67.5 ± 0.2 cm, 72.9 ± 0.2 cm, 13.4 ± 0.1 cm, 19.7 ± 0.1 cm, 12.8 ± 0.2 cm, 14.6 ± 0.1 cm and 13.5 ± 0.1 cm, respectively. The corresponding values for Woyto-Guji female goats were 24.8 ± 0.3 kg, 57.4 ± 0.2 cm, 61.9 ± 0.2 cm, 68.3 ± 0.2 cm, 12.1 ± 0.1 cm, 17.3 ± 0.1 cm, 10 ± 0.2 cm, 13 ± 0.1 cm and 13.4 ± 0.1 cm, respectively. The observed variations in production system and morphological traits among the sample populations coupled with their adaptive traits would indeed justify the need for designing breed improvement programme for both breeds.

Qualitative Characteristics

Eighteen quantitative measurements and fourteen qualitative characteristics taken from 306 adult sheep (57 rams and 249 ewes) were used to characterize sheep populations of district, Ethiopia. Most traits showed significant variation by zone, sex and age groups with higher values generally recorded for rams as compared to ewes. Middle age group animals displayed highest values for several traits, reflecting the optimal production age. zone affected ewes more than rams. The highland sheep height at withers, widest shoulder points and longest hair, indicative of adaptation to their environment. Qualitative characteristics of the studied sheep populations such as tail shape, plain coat color pattern, skin, hairy fiber and the absence of horn, toggle, ruff and beard suggest that they constitute a previously sheep breed. Tan coat color differentiated high and midland sheep from lowland sheep where white and brown colors were dominant. Canon bone length, height at withers and tail length were the three most important variables used in discriminating the sheep populations. On average 66% of the animals could be classified into their respective zone. Our data suggest that highland sheep populations are distantly related to lowland sheep, while midland sheep are more closely related to lowland sheep. It can be concluded that breeding programs specific to each zone need to be designed for sustainable utilization and conservation of the studied sheep populations. Furthermore, molecular based studies might allow further characterization of Ethiopian sheep breeds.

This study was conducted as a preliminary study to design the breeding activity of Mongolian cashmere goats. To characterize the phenotypic traits of goats in Western Mongolia, the linear body measurements and cashmere yield and its the quality were measured. In this study, 608 cashmere goats were selected from the areas where it highly affected to overgrazing and overstocked in this area. The study used a random sampling method from the populations. The normality of the data was checked using the Shapiro-Wilk normality test and analyzed using the linear model procedure in R software. All male (buck) and female goats had straight head profiles (100%). Black coat color was predominant in Erdeneburen, Bayan-Uul soums and all of the goats in Ulgii soum were red. The goats in Ulgii soum were the biggest in body size compared to Erdeneburen and Bayan-Uul in Ulgii soums. The goats had back horn orientation (100%). Significant effects (p <0.001) of sex, age, locations, and sex*age classes were observed on live body weight, cashmere quantitative and qualitative characteristics, and linear body measurements.

Native Pigs

This study was conducted to determine the phenotypic characteristics of native pigs in the province of Romblon. Specifically, it identifies the phenotypic characteristics, morphometric diversity, and effective population size of the native pigs. This study used the descriptive design. The data gathered were statistically analysed using frequency/percentage, mean, regression analysis and correlation. From the analysis and interpretation conducted it was found out that: majority of the snout were long and thin; the head profile was straight; most of the ear type was droopy; the ear orientation were projected forward; have straight hair; the coat color pattern were plain; the coat color was black; the skin were smooth; the tail were straight and the backline was straight except for gilt which is swaybacked. The Shannon Weiner Diversity Index on the phenotypic characteristics of native pigs in the province of Romblon was observed evenly distributed. There is significant relationship observe on the morphometric diversity of native pigs.
