Characterization of Black Bengal bucks and does was performed in this study. A total of 50 goats of different aged were studied. The experiment was performed in Black Bengal bucks and does at 1 day and at 3, 6, 9 and 12 months of age for measuring different parameters such as body length, heart girth, wither height, hip height, fore and hind leg length, head length and width, head length and wi...

Social hierarchies among animal species are based on the ́s dominance-aggressiveness level aligned with subordination oftheir mates. order is mostly defined by size, live weight, or age. This study aimed to evaluate association betweenodor score (OS), horn presence (HP), size (HS), and body temperature social rank hierarchy, scrotal circumference (SC), semenquality (SQ), sexual drive (SD). Adult...

The effect of dry season supplementation with crop-residue-based rations on bodyweight, scrotal circumference and serum testosterone concentrations in Red Sokoto weaner bucks at 5, 6 and 7 months of age was investigated in the present study. There were 7 treatment groups which were fed a positive control ration (conventional concentrate) fed at 1 and 2% of the bucks’ bodyweights (Rations 1A and...

The aim of the present study was to evaluate the effects of different seasons on the morphometric testicular parameters and the respective epididymal sperm parameters. Total numbers of 104 scrota of pubertal buffalo bull (24-48 months) include their contents were provided from the local slaughterhouse. Scrotal circumference was measured on its place before dissection. Morphological parameters o...

Shortening age at puberty of crossbred breeding bull is an important issue in the tropics. This study aimed at selecting crossbred bulls at earliest possible age with bigger scrotum and potential for donating quality semen. One hundred and 31 pre-joining crossbred bulls of Central Artificial Insemination Laboratory, Saver, Dhaka were examined. The bulls being trained by seeing semen collection ...

This meta-analysis review was conducted to determine the relationship between scrotal circumference and semen production quality in bulls. The research method includes article search, selection, assessment stages based on specified inclusion criteria. results of selection articles obtained 38 for meta-analysis. Data analysis performed using CMA program a random-effects model estimate correlatio...

Paternal half-sib heritability and genetic correlation estimates were obtained utilizing data from 578 Hereford bulls from 66 sires. Bulls were maintained in three lines (weaning weight, postweaning gain and control) of an ongoing selection project. Growth performance traits studied were adjusted 205-d weaning weight, 365-d weight, individual feed efficiency, sonoray fat thickness and postweani...

The body measurements of 433 young Dorper rams participating in the Free State and Northern Cape veld-ram projects were correlated with their production performance. These measurements included a selection index, body weight (kg), average daily gain (g/day) and scrotal circumference (cm). The performance of the animals in the two projects compared well, although the means in the Free State proj...
