Molecular characterization of coat color gene in Sahiwal versus Karan Fries bovine

Effect of Molasses Feeding on Biochemical and Hormonal Parameters in Sahiwal and Karan Fries Heifers

The present study was designed to investigate the effect of molasses feeding on biochemical and hormonal parameters in Sahiwal and Karan Fries heifers under two feeding regimes, i.e. feeding regime-1, as per the NRC (2001) and feeding regime-2 having 15 % higher energy (supplementation of molasses) than NRC (2001). Twelve healthy heifers (18-24 month) of each Sahiwal and Karan Fries were select...

Estimation of metabolic heat production and methane emission in Sahiwal and Karan Fries heifers under different feeding regimes

AIM The objective of this study was designed to estimate the metabolic heat production and methane emission in Sahiwal and Karan Fries (Holstein-Friesian X Tharparkar) heifers under two different feeding regimes, i.e., feeding regime-1 as per the National Research Council (NRC) (2001) and feeding regime-2 having 15% higher energy (supplementation of molasses) than NRC (2001). MATERIALS AND ME...

Detection of Single-Nucleotide Polymorphism in the Bovine AGPAT6 Gene Associated with Milk Fat Content using Tetra-Primer ARMS PCR-based Assay in Karan Fries Breeding Bulls

Background: The bovine AGPAT6 gene is one of the potential candidate genes governing milk fat synthesis.Objectives: Identification of single nucleotide polymorphisms (SNP) in the targeted region of AGPAT6 gene and their effect on expected breeding values (EBV) of first lactation milk production traits viz. fat %, fat yield and 305 days milk yield in Karan Fries (KF) breeding bulls were so...

Optimization of dry period in Karan Fries cow

AIM The objective of this study was to optimize dry period (DP) length that can maximize the production across adjacent lactations and overall lifetime yield. MATERIALS AND METHODS Performance records with respect to DP spread over a period of 15-year in Karan Fries (KF) cattle maintained at Livestock Research Centre (National Dairy Research Institute), were collected for the study. Data of 6...
