The aim of the study was to validate and identify Black Bengal goat biometrically to improve animal management in its traceability system.Methods: Forty-nine healthy, disease free, 3 months±6 days old female Black Bengal goats were randomly selected at the farmer’s field. Eye images were captured from the left eye of an individual goat at 3, 6, 9, and 12 months of age using a specialized camera made for human iris scanning. iGoat software was used for matching the same individual goats at 3, 6, 9, and 12 months of ages. Resnet152V2 deep learning algorithm was further applied on same image sets to predict matching percentages using only ca...

The average birth weights of Black Bengal goats obtained in different occasion revealed that there was significance difference (P<0.05) in the average birth weight of male and female kids. Seasonal influence had significance effect (P<0.05) on the birth weight of kids in Bengal goats in coastal zone. Effect of type of birth significantly (P<0.05) differ in the average birth weight in all the four types of birth. In the average birth weight of male and female kids it was found that there was significant difference (P<0.05) in the body weight. Body weight in summer month had no significant difference (P>0.05) where as body weight between monsoon and winter months differs significantly (P<0.05). The birth weight in single kidding recorded to be the maximum while kids in quadruplet or multiple births was the lower weight and was...

For this purpose, whole blood and serum samples were collected form Ayeshpur village (New Alluvial zone or zone-1) located at Mohanpur of Nadia district and villages of Gosaba block (Sunderban coastal area or zone-2) of 24-Parganas district of West Bengal. The mean value of Hb, PCV, TEC, TLC and MCV in New Alluvial Plains is higher than the values in Coastal saline area. Highly significant difference (P0.05) in Coastal zone and Alluvial Plains. The difference in the level of serum electrolytes Potassium and Chloride were found to be higher in zone-2 than zone-1 where as Sodium value was observed as higher in zone-2 than zone-1 resulting a highly significant difference in Sodium and Potassium level.

Information from 10,348 kids born from 3,138 Black Bengal does during the period April 2010 to March 2019 reared at farmers' fields, was used to study the effect of non-genetic and genetic factors on reproduction traits. Age at first service (AFS) and age at first kidding (AFK) from 1,175 does; service period (SP) and kidding interval (KI) and litter size (LI) were considered for this study. Agro-climatic clusters, year of kidding and season of kidding were included as non-genetic factors whereas; parity of doe was taken as a genetic factor. The mean AFS and AFK were recorded to be 239.86±0.72 and 400.60±2.33 days respectively. The average SP was reported as 88.32±0.93 days, the average KI was 235.48±0.91 days and overall litter size/ kidding were 1.84±0.01 kids. Effect of cluster, season, parity and year of kidding had a significant effect on the reproduct...

Thus, the aim was to validate real-time rectal temperature (RT) data of radio frequency based digital (RFD) thermometer with RT data of mercury bulb (MB) thermometer in female Indian Murrah buffaloes (Bubalus bubalis). In experiment I, six buffaloes were used to record RT for 2 h on empty stomach and 2 h after feeding at 0, 30, 60, 90 and 120 min using RFD thermometer as well as MB thermometer. In experiment II, six buffaloes were again used to record RT for 2 h before exercise and 2 h after exercise at 0, 30, 60, 90 and 120 min. Two way repeated measures analysis of variance (ANOVA) with post hoc comparisons by Bonferroni test showed that there was no significant difference (P>0.05) between RT data recorded by RFD thermometer as well as MB thermometer throughout the monitoring period. The RT data recorded by RFD thermometer and by MB thermometer were increased (P<0.05) following feeding and exercise in buffaloes. The results obtained in the present study suggest that the body temperature recordings from RFD thermometer could be used for monitoring real-time RT in buffaloes.

Thus, the aim of the current study was to validate the real-time rectal temperature (RT) data of radio frequency based digital (RFD) thermometer with RT data of mercury bulb (MB) thermometer by conducting three experiments in Black Bengal goats. In experiment I, six non-pregnant Black Bengal does with a mean (±SEM) body weight of 10.93 ± 1.33 at the age of 2.25 ± 0.11 years were used to record RT for 2 h on empty stomach and 2 h after feeding at 0, 30, 60, 90 and 120 min using RFD thermometer as well as MB thermometer. In experiment II, previously selected six does were further used to record RT for 2 h before exercise and 2 h after exercise at 0, 30, 60, 90 and 120 min. In experiment III, twelve non-pregnant Black Bengal does with mean (±SEM) body weight of 15.83 ± 2.16 kg at the age of 3.61 ± 0.43 years were challenged with lipopolysaccharide (LPS) μg/kg body weight and RT was recorded at 15 min interval for 1 h prior to the administration of LPS at −60, −45, −30, 15 and 0 min (0 being the time of LPS administration) and then every 15 min interval for 5 h post LPS administration up to 300 min. Two way repeated measures analysis of variance (ANOVA) with post hoc comparisons by Bonferroni test depicted that there was no significant difference (P > 0.05) between real-time RT data recorded by RFD thermometer as well as MB thermometer before and after feeding/exercise/LPS administration. Both RFD thermometer and MB thermometer recorded increased (P

Mostly the women (91.3%) of the farming families in West Bengal rear goat. Goat rearing is a subsidiary income source to rural poor along with agriculture. In majority of cases the flock size ranges from 1 to 4 (56%). Male female ratio in adult flock is observed as 1:8 in field condition. The animals are mostly housed along with residential housing (67.1%); houses are mostly kachha type (82.63%) with earthen floor (86.47%) and straw roof (91.33%). All most all the farmers used to graze their goats for feeding. Ponds water is the major source for drinking water (58.14%) of goats. Black Bengal Goats have natural resistant power to many diseases but are vulnerable to cold, water logging situation, diarrhoea, ecto and entro parasitic infestation and respiratory diseases. Under field condition mortality rate is 9.63%.

The aim of this study was to validate real-time rectal temperature (RT) data of radio frequency based digital (RFD) thermometer with RT data of mercury bulb (MB) thermometer in dairy cattle. Materials and Methods: Two experiments were conducted. In experiment I, six female Jersey crossbred cattle with a mean (±standard error of the mean) body weight of 534.83±13.90 kg at the age of 12±0.52 years were used to record RT for 2 h on empty stomach and 2 h after feeding at 0, 30, 60, 90, and 120 min using a RFD thermometer as well as a MB thermometer. In experiment II, six female Jersey crossbred cattle were further used to record RT for 2 h before exercise and 2 h after exercise at 0, 30, 60, 90, and 120 min. Two-way repeated measures analysis of variance with post hoc comparisons by Bonferroni test was done. Results: Real-time RT data recorded by RFD thermometer as well as MB thermometer did not differ (p>0.05) before and after feeding/exercise. An increase (p<0.05) in RT after feeding/exercise in experimental crossbred cattle was recorded by both RFD thermometer and MB thermometer. Conclusion: The results obtained in the present study suggest that the body temperature recordings from RFD thermometer would be acceptable and thus RFD thermometer could work well for monitoring real-time RT in cattle.

The two sub regions are GFP (Gangetic Flood Plane) and CFP (Coastal Flood Plane). The information pertaining to the present study was collected from two hundred ninety three (293 nos) goat farmers by participatory and rapid rural appraisal techniques in repeated interactions. The group receiving compound feed along with broken wheat & maize combination attained maximum growth i.e. 13.34 kg followed by growth in Compound Concentrate Feed & Broken Wheat; Compound Concentrate Feed, Broken Wheat & Rice; Compound Concentrate Feed; Broken Wheat & Rice bran and Broken Rice & Rice bran was 12.84, 12.66, 12.28, 12.08 &11.71 kg, respectively.
