Abstract Our objective was to evaluate the reproductive performance of Holstein nulliparous heifers carrying SLICK1 mutation and half-sisters not mutation. Heifers were born between November March 2020 two sires heterozygous for dominant allele raised in four dairy farms San Joaquin Tulare basins California Central Valley. bred from January September 2021 according farm protocols. Data obtained...

Production traits of 60 indigenous (Desi), 20 Friesian × Desi and 20 Sahiwal × Desi cows were recorded in six char villages of Sariakandi upazila (Sub-district) of Bogra district. The mean (± SD) daily milk yields were 1.7 ± 0.6, 6.3 ± 1.2 and 5.1 ± 1.0 litres, respectively. The lactation lengths, ages at puberty, gestation lengths, calving intervals, numbers of services per conception, interva...

Pre-slaughter live weight, dressing percentage, and hot standard carcase weight (HCWT) from the 2007, 2008, 2009 and 2010 birth-years of the Information Nucleus Flock Lambs (n=7325) were analysed using linear mixed effects models. Increasing the sire breeding value for post-weaning weight (PWWT), and c-site eye muscle depth (PEMD), and reducing the sire breeding value for fat depth (PFAT) all h...

A cross sectional study was done to understand the effect of genotypes, farm management and agro-climatic conditions in Kerala and Uttar Pradesh on seroprevalence of Mycoplasma mycoides Subsp. capri (Mmc) in goats. Goat serum was screened by Slide Agglutination test (SAT) for Mmc antibodies. It was found that there was no statistically significant difference (P>0.05) in mycoplasma seroprevalenc...

After the analysis of the relation between the serum protein and the immunoglobulin-G content of the colostrum and the milk of 141 cattle of various genotypes (pure-bred or cross-bred), 55 goats of various breeds and 171 sheep of various breeds, it was established that there exists a very close correlation between these two components in all three species. R values of 0.9869 for cattle, 0.9723 ...

Coffee farms are often embedded within a mosaic of agriculture and forest fragments in the world's most biologically diverse tropical regions. Although shade coffee farms can potentially support native pollinator communities, the degree to which these pollinators facilitate gene flow for native trees is unknown. We examined the role of native bees as vectors of gene flow for a reproductively sp...
