The study was conducted to evaluate the effect of phytoadditive mixtures containing equal proportions of Curcuma longa & Allium sativum (PAM-1) and Curcuma longa & Ocimum sanctum (PAM-2) on live weight, blood parameters, hormonal profile and reproductive performance in Black Bengal goats. A total of 21 post weaned female kids of 3-4 months age and similar body weights maintained at Goat Research Unit of Eastern Regional Station (ERS), National Dairy Research Institute (NDRI), Kalyani, India during the year 2021-2022 were randomly distributed in three groups namely, Control, PAM-1 and PAM-2 for 10 months. Blood parameters i.e. glucose, urea, total protein, albumin, globulin, ALT, AST, ALP, total lipids, cholesterol, and Triglycerides, WBC, RBC, Hb and PCV %; NEFA levels and hormones i.e. prolactin, cortisol, T3 and T4 were estimated in all three experimental groups. Higher (P < 0.001) live weights were investigated in supplemented goats. Blood parameters including glucose, urea, total protein, albumin, globulin, ALT, AST, ALP, WBC, RBC, Hb and PCV% were similar (P > 0.05) in all groups. Lower (P < 0.001) blood lipids were found in supplemented groups. Higher Prolactin, T3 and T4 levels and lower Cortisol levels were reported in PAM-1 and PAM-2 groups (P < 0.001) than control group. Age at first estrus, first conception, first kidding and post kidding first estrus days were lower (P < 0.001) in supplemented groups. Therefore, it was concluded that supplementation of PAM-1 and PAM-2 improved reproductive performance, hormonal profile and lipid profile through improved live weights in Black Bengal goats.

This study assessed the effect of a thermo-insulated kid barrel (KB) on the behavioral, physiological, and morphometric growth performance of winter-born Black Bengal goat kids. Two groups were studied: one group was housed in a goat shed without a thermo-insulated kid barrel (control group), while the other group was housed in a shed with a thermo-insulated kid barrel (kid barrel group). Each group consisted of six kids along with their mothers. Due to the lack of independent replication, the results are presented descriptively. During the winter, microclimatic conditions inside the KB were consistently warmer than those in the goat shed. Kids in the kid barrel group spent 60% of their time inside the KB during the pre-weaning period. Morphometric traits of the kids were better in the kid barrel group compared to the control group during both pre- and post-weaning periods. Additionally, post-weaning feed intake was higher in the kid barrel group. In conclusion, providing a thermo-insulated kid barrel as an ancillary housing structure during winter improved the overall performance of goat kids..

The effect of dietary inorganic and organic chromium (Cr) on body morphometry, carcass traits, and nutrient composition, including different minerals and fatty acids in meat and internal organs of Black Bengal goats, was studied. Thirty weaned Black Bengal kids of 3–5 months (5.40 ± 0.34 kg body weight) were assigned randomly into five groups and fed additional Cr for 150 days. The experimental diets comprised a basal diet supplemented with Cr at the rate of 0 (control; without Cr supplementation), 1.0 and 1.5 mg/kg of inorganic Cr (Cr(III)-chloride), and 1.0 and 1.5 mg/kg of organic Cr (Cr-yeast). The body morphometry such as body length, heart girth, paunch girth, loin width, leg circumference, and the carcass traits, namely, slaughter body weight, dressing percentage, hind quarter and forequarter weight, and rib eye area of goats, were not significantly (P < 0.05) changed due to inorganic and organic Cr supplementation. However, organic Cr supplementation (1.0 and 1.5 mg/kg) resulted in a reduction of breast and back fat thickness (P < 0.05) compared with the control group. The weights of internal organs including liver, lungs, spleen, kidney, testes, and heart and their weights as a percentage of slaughter weight were similar (P > 0.05) among different experimental groups. Dry matter, ether extract, and total ash concentrations of muscle and internal organs of Cr-supplemented groups were not affected (P > 0.05) by Cr supplementation. However, crude protein contents in the liver, muscle, kidney, and lungs were greater (P < 0.05) in the organic Cr groups than in the control and inorganic Cr groups. In meat (longissimus dorsi muscle), total saturated fatty acid concentration was lower (P < 0.05; 59.4

Frequent extreme weather events result in substantial economic losses for farming communities, posing a significant threat to the livelihood security of smallholder farmers in the Sundarbans region of India. Various agricultural enterprises in this area are continually at risk due to saline water intrusion, crop damage from heavy rainfall, and flooding. We examine the strategies farmers have adopted to sustain their livelihoods in the face of these extreme weather events. We collected primary data from a randomly selected sample of 1,200 farmers across six blocks in the Sundarbans region, focussing on farm households engaged in diverse agricultural enterprises, including field crop cultivation, livestock rearing, and fish farming. We used the Analytical Hierarchy Process (AHP) to prioritize the coping mechanisms adopted by these farming communities. The assessment of coping mechanisms was based on four criteria: ease of implementation, cost, effectiveness, and durability for long-term application. Effectiveness got the highest weights of 0.492 followed by the durability of the coping strategy weights of 0.309. Coping mechanisms pertaining to managing soil health against soil salinity, raising livestock and fish species as well as cultivating field crops were identified and prioritized according to their perceived efficacy against extreme weather events. Our results can inform the formulation of robust and sustainable development policies for agricultural and allied sectors in the Indian Sundarbans.

This study investigated arsenic (As) concentrations in diverse environmental components and their potential impact on the health risks faced by residents of the arsenic (As)-contaminated Nadia district in West Bengal, India. A random selection of 182 cattle and 255 goats from 40 livestock farmers in the district revealed that both animals and humans were naturally exposed to elevated arsenic levels through contaminated drinking water, foods, grasses, concentrate feeds, various fodder tree leaves, and other food/feed resources. The mean As concentration in roughages (483.18 µg/kg DM) was significantly higher (p < 0.001) than in tree leaves (391.53 µg/kg DM), and concentrate feed/ingredients (186.66 µg/kg DM). Pond water exhibited higher arsenic levels (106.11 µg/L) compared to shallow tube well water (47.96 µg/L) and deep tube well water/tap water (10.64 µg/L and 10.04 µg/L, respectively). The mean arsenic concentration in soils DM of fodder fields, crop fields, and grassland was 10.25, 10.58, and 10.20 mg/kg, respectively. It was observed that protein-rich feeds had lower levels of arsenic accumulation (p < 0.048), while fiber-rich feeds containing more cellulose, hemicellulose, and lignin had higher arsenic levels (p < 0.017). Goats consumed 73.46

The present study was conducted to evaluate the effect of feeding conch shell (Turbinella pyrum) powder (either fresh or calcined) as a marine organic source of calcium (Ca) supplemented in the diet of crossbred calves on voluntary intake, growth performance, and blood biochemistry in growing crossbred Jersey calves. A growth trial of 90 days was conducted on 15 Jersey crossbred female calves (Av. weight, 70.68 ± 2.90 kg; Av. age, 197.73 ± 12.40 days), equally divided into three groups of 5 animals each, i.e., control (T0), treatment 1 (T1), and treatment 2 (T2). All animals were fed total mixed ration (TMR) prepared with a concentrate mixture, chaffed paddy straw, and green fodder at the ratio of 40:30:30 on DM basis. Calves under the control group were fed with TMR containing a standard mineral mixture having dicalcium phosphate (DCP) as a Ca source. Calves under T1 group were supplemented with TMR containing fresh conch shell powder (FCSP), and T2 calves were fed with TMR containing conch shell calcined powder (CSCP) as Ca source. We observed 11.66

The present study was performed to evaluate the influence of dietary inorganic and organic chromium (Cr) supplementation on blood biochemical constituents and mineral concentrations as well as the changes in the mineral composition of internal organs of Black Bengal goats. Thirty Black Bengal kids of 3 to 5 months (5.40 ± 0.34 kg body weight) were allocated randomly to five treatment groups. The five groups were control (without added Cr in a basal diet), 1.0, 1.5 mg/kg of inorganic Cr, 1.0, and 1.5 mg/kg of organic Cr added per kilogram of feed dry matter. The duration of the experiment was 150 days during which the changes in the blood biochemical and mineral concentrations at 0, 30, 60, and 150 days were evaluated. At the end of the trial, mineral composition in the muscle, skin, and internal organs (liver, lungs, kidney, heart, spleen, and testis) were analyzed. Any blood variables were not affected at or before 60 days of Cr supplementation. Both inorganic and organic Cr supplementation lowered (P < 0.05) concentrations of blood glucose, cortisol, non-esterified fatty acids, and β-hydroxybutyric acid after 60 days of Cr supplementation. Organic Cr-supplemented groups exhibited higher (P < 0.05) blood insulin concentration and neutrophil activity compared to the control. Supplementation of Cr in either form had no substantial effect (P > 0.05) on the blood hemoglobin, total leukocyte count, total protein, albumin, globulin, immunoglobulin G, total antioxidant capacity, and liver enzymes (aminotransferases) concentration, and also blood minerals (zinc, iron, and manganese) concentration. Blood Cr and copper concentrations were increased (P < 0.05) due to both organic and inorganic Cr supplementation. Minerals (calcium, phosphorus, magnesium, iron, zinc, copper, and manganese) concentrations of internal organs of Cr-supplemented groups were mostly not affected (P > 0.05) by Cr supplementation. However, the concentrations of Cr and copper in blood and Cr in all internal organs, skin, and muscle of organic Cr-supplemented groups were higher (P < 0.05) than in those fed the basal diet. In conclusion, dietary inorganic and organic Cr supplementation, especially the organic form, after long term supplementation (> 60 days) could be beneficial in regulating blood glucose and fat metabolism and the immune status of Black Bengal goats.

Farm households in the UNESCO World Heritage site Sundarbans face serious problems, including increased soil salinity, frequent extreme weather events, seawater intrusion and flood damage, all of which cause distress to the livelihoods of the farm families. Policymakers commonly acknowledge livestock as a crucial resource for mitigating economic losses caused by crop failures due to extreme weather events. Despite Sundarbans' vulnerability to extreme weather events, smallholder farmers' livelihoods vary across the region. Identifying spatial livelihood variations aids in targeted strategies to address climate extremes. We chose the highest cow- and buffalo-populated blocks among the 19 blocks in the Sundarbans to assess variations in livelihood dimensions, including nutritional, economic, social and infrastructural security. We used dummy variable regression models to examine the differences in livelihood security dimensions among households living in different locations. The study found that Namkhana had the highest livelihood security score among the blocks studied, while Gosaba had the lowest score because it's in a remote area with limited infrastructure. The study found a significant difference in the overall livelihood security score among the blocks we examined, indicating the need for a location-specific, cluster-based approach for the overall development of the Sundarbans. The study can shape a policy framework for socio-economic development in the Indian Sundarbans through its findings on location-specific livelihood security. For securing smallholder farmers' livelihoods in the vulnerable Sundarbans region, policymakers must give priority to improving infrastructure, viz., roads, marketing facilities and animal healthcare centers.

Background and Aim: Alpha-tocopherol supplementation influences milk yield, milk quality, and udder health of dairy cows, which needs to be investigated for Jersey crossbred cows at hot-humid climate. Therefore, the present study was framed with an objective to study the effect of pre and postpartum Alpha-tocopherol supplementation on milk yield, milk quality, and udder health status of Jersey crossbred cows at tropical climate. Materials and Methods: For this study, 19 similar parity, body condition score, and production level dairy animals were separated randomly into three groups, namely, Control, T1 and T2. Control group (no supplementation) was compared with two treatment groups, namely, T1 and T2. Supplementation of Alpha-tocopherol was done in concentrate fed to the animals (at 1 g/cow/day) 30 days prepartum to 30 days postpartum in T1 and 30 days prepartum to 60 days postpartum in T2 groups. Observations were taken for different parameters up to 5 months of lactation. Results: Statistically analyzed data revealed that overall significantly (p<0.01) more milk production was found in T2, followed by T1 than the control group. Overall significantly (p<0.01) lower somatic cell counts and modified California mastitis tests were recorded in T2, followed by T1 than the control group. Overall significantly (p<0.01), better milk quality in terms of methylene blue reduction test was found in T2, followed by T1 than control groups. Differences in the milk composition of all three groups were non-significant (p>0.05). Conclusion: Supplementation of Alpha-tocopherol during prepartum to initial lactation period may enhance milk yield, milk quality, and udder health status of Jersey crossbred cows at the tropical lower Gangetic region.
