The present study was carried out to investigate the growth performances of Black Bengal goats reared under four different agro-climatic regions of West Bengal as well as different managerial practices during January 2012 to December'2013. Although birth weight did not show significant (p>0.05) variation irrespective of zones and rearing systems, higher birth weight was recorded in Undulating Red and Lateritic zone (1.149±0.036 kg) and Coastal Saline zone (1.148±0.053 kg) than the Gangetic Alluvial zone (1.115±0.048 kg) and Terai-Teesta Alluvial zone (1.047±0.057 kg). The zone-wise variation of body weights at 0-3 months, 3-6 months, 6-9 months and 9-12 month and above age group remained highly significant (p<0.01). At 0-3 months of age group the highest body weight was recorded in Coastal Saline zone (6.368±0.102 kg), followed by Gangetic Alluvial (5.814±0.126 kg), Undulating Red and Lateritic (5.405 ±0.105 kg) and Terai-Teesta Alluvial region (4.922±0.098 kg). At 3-6 mon...

Goats are an important contributor to the rural economy providing food and nutritional security along with self-employment opportunities to the small and marginal farmers. It being free from any religious taboos is the choicest meat in India with huge demand for chevon. Medicinal properties of goat milk is arousing the interest and the demand of goat meat a step further. Black Bengal goats are the dwarf goats found in northeastern India like West Bengal, Odisha, Jharkhand etc. which are a good source of meat, milk, and leather. The productivity of goats under the prevailing traditional production system is very low because they are maintained under the extensive system on natural vegetation on degraded common grazing lands and tree lopping. Therefore it is imperative and mandatory to rear goat under intensive and semi-intensive system using improved technologies for commercial production. Current study deals with the growth traits, absolute as well as relative, as recorded in Black Bengal goats under farm system of management. Absolute growth traits observed included body weight at birth, 1months, 2months, 3 months and 6months. Relative Growth traits included 1-3 months body weight gain and 3-6 months body weight gain. Significant effect of different factors i.e. sex, parity, type and season of birth was observed on various traits under study. It might be concluded that the intensive and semi-intensive system of management will help in realizing the full potential of Black Bengal goats and will also meet the increasing demand of chevon (goat meat) in the domestic as well as international markets.

Data on 10148 Black Bengal kids recorded from 2008 to 2019 and maintained at farmer's fields at different agroclimatic clusters of West Bengal under the project "AICRP on Goat Improvement, Black Bengal Field Unit-Kolkata" were used to study the effect of non-genetic factors on body weight from birth to 12 months of age. The data were analysed using least squares analysis technique. The average birth weights of Black Bengal goats obtained under four different agro-climatic clusters revealed that there was a significant variation in body weight (kg) of all ages. The effect of year of kidding, influence of season and parity of the dam on body weight of Black Bengal kids at different ages were significant. But a non-significant result was found at the body weight in all the seasons as well as in all the parities at 9 and 12 months of age. Sex of the kid and type of birth had significant effect on body weights from birth to 12 months of age. Significantly higher body weight at birth was recorded in single born kid, followed by twin and triplets. The study concluded that it is possible to improve non-genetic elements in the field, particularly by providing excellent housing, reducing stress, having access to grazing pasture, and doing routine deworming and vaccinations. The findings supported the need for environmental changes that can aid in the development of management strategies and decision making regarding the selection.

The Pharma Innovation Journal, 2022
ICAR Research Complex for NEH Region, Tripura centre is maintaining a Black Bengal goat farm to cater the need of farmers and institute research. The data collected for 5 years regarding pre-weaning growth performance of kids and analysed. The birth rate of Black Bengal kids were recorded in institute goat farm, averaging 1.61 kids per doe and the prolificacy rate was 146.54%. The percentage of single birth was recorded as 27.87%, multiple births as 72.13.7% out of which 57.54% was twin, 13.43% was triplet and 1.16% was quadruplet. The overall birth and weaning weights of Black Bengal kids were 1.11 ± 0.06 kg and 4.82 ± 0.20 kg, respectively and pre-weaning average daily gain was 41.22 ± 3.15 gm. In the study it was found that the birth weight of male and female kids was 1.12±0.07 kg and 1.07±0.04kg, respectively. Even though male kids recorded 4.46% higher body weight than female kids but, no significant difference was observed. Birth weight, weaning weight and pre-weaning daily gain of single, twin, triplet and quadruplets born kids were 1.
In India, where more than 50% of farmers are small, marginal or landless, Goat rearing plays a very important role in their lives for generating source of income and employment. The Black Bengal Goats were treated by 3 different treatments with different concentration of feeding components. The treatment 3 was composed of green leaves of trees, common grasses, bushes and legume (berseem) as roughages along with maize (40%), wheat bran (45%), groundnut (12.5%), salt (1.5%) and mineral mixture (1.5%) as concentrate. By this treatment, the overall growth and reproductive performance of the Black Bengal Goats were found to be higher as compared to the feeding plans in which only roughages or only concentrates were fed as in case of treatment 1 and treatment 2. Based on growth and reproductive performance, production per unit was determined for each of the treatment 1, 2 and 3 i.e. 1.429, 1.714 and 2.429 respectively. It was confirmed that the net profit in terms of rupees was higher in treatment 3 i.e. Rs. 886.59 as compared to the treatment 2 and treatment 1, whose net profits were Rs. 625.61 and Rs. 521.59 respectively. Based on these findings the cost benefit ratio (BC Ratio) was 2.24. INTRODUCTION Goats are among the first animals domesticated for meat and have been raised by human for food and livelihood for a time being. Small, marginal and landless farmers contribute 75.8% and medium and large farmers contribute 24.2% of Goat farming in the rural areas [8]. So, Goat plays a dominant role in small ruminant production systems and as a means of livelihood in the rural landless farmers. Goats are also considered to be "The Poor Man's Cow" as it is being small in size; they do not require any large management skills and can easily be handled and managed by women and children [1]. They are traditionally raised by " poverty-stricken " village people in a secondary system of grazing on harvested fallow land, along the road and canal sides without any supplementation [3]. But with the tremendous increase with the human population along with the demand for red pretentious meat, farmers are now trying to adapt and rear Goat under intensive management system. It was also reported that farmers were bound to depend on the community based buck breeding system with unknown pedigree. As a result, unplanned and haphazard breeding has been performed in our country [2]. In some cases, it is a matter of great concern that crossbreeding is being performed which not only decreases the purity but also increases the heterozygosity of this breed day by day. On the other hand, due to unavailability of Black Bengal breeding bucks, the same buck has been used generation after generation. As a consequence, inbreeding depression may be increased which is ultimately responsible for the gradual decline of overall productivity of Goat [12]. The successful Goat husbandry largely depends on the environment where the Goats are reared with their management system. Adult body weight is an important and economic factor which influences on the growth and production pattern of Goat enterprise and has more influence mainly

The present experiment was studied to investigate the effect of genetic and non-genetic factors on productive performances of Hilly Brown Bengal (HBB) goats at the research farm. For this purpose, initially, a total of 69 does of different generations and 20 bucks and finally, a total of 76 does and 09 bucks were used to study productive parameters of HBB goat. The studied Animals were reared in a semiintensive management system with natural breeding facilities. Goats were allowed to browse for 6-8 hours and mounting in hills with two times concentrates supplementation @ 1% of their body weight. Here three seasons, three generations were considered and parity was counted up to fifth. The data were statistically analyzed by using least-squares analyses of variance of the general linear model (GLM) procedure of the SPSS, 20.00. Sex of kids was significantly (p<0.05) affect the birth weight of kids, where male kids had higher birth weight (1.24 kg) than female kids (1.15 kg). Kids born in summer season had higher birth weight, litter weight, liter size, placental weight, kidding frequency, fortnightly body weight gain up to 6 months, pre and post-weaning gain with reduced mortality rate. Statistically, in summer season, approximately 11.22% and 3.45% heavier kids born, 9-10 g higher daily gain occurs in pre and post-weaning periods and 900-1100 g higher body weight at 3 months of age were found when compared with rainy and winter season respectively, where rainy season had highest body weight at 6 and 9 months of age. Highest percentage of total kidding (41.61%) was also found in summer season with reduced mortality rate (14%), while the highest mortality (64%) occurred in rainy season. Dams parity had significant (p<0.01) impact on production performances and kids mortality rate, where kids litter weight (1.60 to 2.35 kg), litter size (1.38 to 2.08) and placental weight (246.85 to 263.77 g) were increased linearly with the increment of parity up to four, while kids mortality were reduced from 36.57 to 8.44% with the increment of parity up to 5 th. Results suggested that the trends of multiple births (twin and triplet) were increased with the advancement of parity, where twin and triplet kid composition increased linearly from 21 to 68% and 0 to 18% among the total kids born, respectively, while single kid percentage reduced from 79 to 14%. Best productive performances of goats were attained in 1st generation with its highest value of kids' birth weight, weaning weight, litter weight and litter size. There had significant effect (p<0.01) of birth type on kids birth weight, body weight changes and placental weight, where single kid had 30.85% heavier birth weight than the quadruplet with highest placental weight (219.77 to 257.45 g), while highest dams post-partum weight losses (4.8 kg) occurred in triple kidded does. Reduced kid mortality from 36.56 to 1.76% and 51 to 18% can be obtained with the increment of kids' birth weight and age, respectively.

The objective of the study was to evaluate the growth and reproductive performances of Hilly Brown Bengal (HBB) goats of different generations and conducted at Naikhongchari Regional Station Research Farm of Bangladesh Livestock Research Institute. Goats were reared in a plastic slated floor under semi-intensive system and were allowed to graze for 6-7 hours per day. Animals were given a concentrate mixture containing 17% CP, 11 MJ ME/kg DM provided twice daily in the morning and evening at the rate of 1% of their body weight. All goats were kept separately according to sex and age groups to avoid random mating. Natural mating program was performed to improve the economically important traits. Goats were de-wormed and diping on regular intervals and only PPR vaccine was given at the age of 2 months. Data on productive, reproductive and disease incidence of goat were recorded regularly and were analyzed. Results showed that Kid Birth Weight of HBB goats were significantly (P<0.01) differ among generations. Birth weight of G 3 (1.21±0.013 kg) was higher than G 5 , G 4 , G 2 and G 1 (1.11±0.01 kg). Goat body weight of 3, 6 and 9 months age were non-significant among generations. The age and weight at first conception were significantly (p<0.05) differ among generation. Age at first conception was lower of G 4 (301.57±9.06 days) and higher of G 1 (259.80±18.87 days) but body weight at first conception of G 1 (12.23±0.47 kg) was higher and G 4 was lower (10.65±0.52 kg). Age at first kidding, gestation length and kidding interval was not significant (P>.05) effect on generations. Parity had no significant (P>.05) effect on kid birth weight but significantly (p<0.01) differ of Kid litter weight and litter size. According to birth type single kid was highest birth weight (1.21±0.08 kg) than double kid followed by triplet and quadruplet. Mortality percentage of HBB kids at the age of 0-90 days were 13.08±0.23%. It may be concluded that kid birth weight, age and weight at first conception of HBB goat were significantly (P<.05) affected on generation but age at first kidding, gestation length and kidding interval were non significantly (P<.05) affected.

The study was conducted to compare the productive and reproductive performances of Black Bengal and Jamnapari goat under semi-intensive system in Bangladesh. Average birth weight of kids of Black Bengal and Jamnapari was 956.13±19.72 and 1776.56±75.13 gms, respectively. In case of single litter the birth weight of Black Bengal and Jamnapari kids was 962.5±130.14 and 1773.33±388.62 gms, whereas in twin it was 967.17±139.68 and 1816.67±486.11 gms and in case of triplet it was 929.55±90.7 and 1500 gms, respectively. Birth type showed significant difference (P<0.05) between the breeds. A negative correlation was found between the litter size and the birth weight of kids. It was observed that in case of does the average body weight was 14.65±2.84 kg and 30.4±9.08 kg in case of Black Bengal and Jamnapari goat respectively. The service per conception was 1.45±0.5 and 1.34±0.48 in Black Bengal and Jamnapari goat, respectively. The average gestation period was 147.9±1.6 and 150.88±4.7 day...
Bakerwal (Kagni) are heavy goats reared in large flocks under extensive system for meat and household milk purpose by Bakerwal tribe of Jammu and Kashmir. A study was undertaken to study dam weight and effect of some non-genetic factors on birth weight and morphometric traits at birth of Bakerwal goats in organized farm. The data pertaining to dam weight at kidding (DW), birth weight (BW), Body length (BL), height at weathers (BH), Heart girth (HG), paunch girth (PG) were collected from history sheets of Bakerwal (Kagni) goats maintained at Mountain Sheep and Goat Research Station, SKUAST-K, Shuhama, Kashmir, India from 2016 to 2021. The effect of non-genetic factors on birth weight and morphometric traits was studied by least-squares analysis owing to non-orthogonal data using the technique developed by Harvey (1990) [8]. The coefficient of variation (CV %) of all the traits under study were low (7.37%) to medium (32.62%) indicating corresponding low to medium variability of these traits in Bakerwal kids. The overall estimates of 2.97±0.07 kg, 32.11±0.37 cm, 33.60±0.34 cm, 31.97±0.57 cm, 29.88±0.45 cm, 11.03±0.33 cm and11.15±0.50 cm for BW, BL, BH, HG, PG, CL and CC, respectively were obtained in the present study. The effect of period was significant (p<0.05) only on BL whereas the effects of sex of kid and dam weight were significant only (p<0.05) on the BW. The effect of birth type was significant (p<0.05) on the BW. The effect of period of birth was found to be significant (p<0.05) on BL and PG only in the present study. All the phenotypic correlation among all studied traits Bakerwal kids were positive (except between CL and BH) ranging from very low (-0.12) to high (0.54) between BG and BL. It is concluded that heavy goats produce heavy kids of larger size.
