Mammalian sperm mitochondrial sheath harbors a number of enzymes that are involved in release of energy via oxidative phosphorilation of ATP. The present study was designed to detect the effect of differential sperm mitochondrial activity on the fertility potential and the association of sperm mitochondrial activity index (SMAI) with the sperm motility parameters for cryopreserved semen samples...

The current study was undertaken to evaluate the invitro effect of zinc treatment on the Superoxide Dismutase (SOD) and Catalase status in the heat stressed Peripheral Blood Mononuclear Cells (PBMC) of periparturient indigenous and crossbred cows. Twelve pregnant cows, six each from Sahiwal and Karan Fries in their second parity were selected for the experiment. Blood samples were collected at ...

Staphylococcus aureus has been reported as a major pathogen in dairy animals. The pathogenic potential of S. aureus isolates is attributed to a combination of extracellular factors and invasive properties that are controlled at the genomic level. In order to elucidate patterns of pathogenic genes, 346 isolates of S. aureus were recovered from Sahiwal, Karan Fries (cattles) and Murrah (buffalo) ...

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...

The study had two objectives, namely, to estimate the andrological disorders leading to disposal of Karan Fries (KF), Sahiwal cattle and Murrah buffalo bulls and to study the effect of various factors (species/breeds, season of birth and period of birth) on male reproductive parameters. Records on occurrence of subfertility problems and disposal pattern of bulls maintained at the National Dairy...

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...

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).
