The standard of comparison for dairy production records is the 305-day lactation, and much research has been directed to estimating 305-day milk and fat records from incomplete or in-progress records. This study was to determine the effect of several methods of extending incomplete records on sire evaluation. Complete 305-day milk and fat records of first lactations of 73,724 daughters of 1,362...

Background & Aim: In traditional medicine, Boswellia species gum resin known as Frankincense or Olibanum, has been administrated in elderly for enhancement of memory and also in pregnant women to increase memory and intelligence of progeny. However, it has been rarely scientifically documented so far. We have previously reported that maternal administration of Frankincense during lacta...

the objective of this study was to investigate the effect of birth weight (bw) on future milk production and reproductive performance in iranian holstein cattle. records of holstein cows between 1967 and 2010 were obtained from the animal breeding center of iran. birth weights within each herd were grouped into five categories based on the standard normal distribution curves (z ≤-0.8416, -0.841...

background: breast milk is important for the overall well-being of infants. although lactation is relatively robust in the face of poor nutrition, the implication of poor nutrition on non-nutritive factors in breast milk is inconclusive. objective: this study was designed to find associations between nutritional and immune factors in maternal blood and breast milk with the aim to improve the ne...

Increased productivity in the industry can be achieved by breeding for productive longevity through searching and using genetic markers. The study analysed data of 1476 animals with at least one completed lactation. Depending on linear affiliation kappa-casein gene genotype servicing bulls, their female offspring were divided into 4 groups. CSN3 A allele frequency studied bulls was 81.91%, B 18...

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...

AIM The aim was to estimate genetic factors affecting the first lactation milk production traits in Kankrej cattle of North Gujarat. MATERIALS AND METHODS The 475 first lactation records of Kankrej cows that were maintained at the Livestock Research Station, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar, Gujarat, over a period of 35 years from 1980 to 2014 were studie...
