Physiological Performance of Crossbred Cattle Calves (Karan Fries) under Different Housing Conditions during Different Seasons

Performance Evaluation of Karan Fries and Karan Swiss Cattle under Closed Breeding System

The 490 and 380 performance records of Karan Fries and Karan Swiss cows developed through crossbreeding followed by inter-se mating were evaluated for production, reproduction performance and disposal rate. Duration of study (1982-92) was grouped into five periods (1982-83; 1984-85; 1986-87; 1988-89; 1990-92) and each year was divided into four seasons (Winter: Dec.Jan.; Spring: Feb.-March; Sum...

Disposal rate in different age groups of Karan Fries (Crossbred) males in organized herd

AIM The present study was carried out to analyze the disposal rate in different age groups of Karan Fries (KF) males in National Dairy Research Institute herd. MATERIALS AND METHODS Records on 1740 KF crossbred bulls born during the period 1997-2012 were collected with an objective to ascertain the effect of genetic and non-genetic (Period of birth and season of birth) factors on the disposal...

Productive and Reproductive Potentialities of Different Genetic Groups of Crossbred Cows Reared under Different Farming Conditions

A cross-sectional comparative study was carried out to investigate the productive and reproductive performances of different genetic groups of crossbred cows at three different farming conditions in Bangladesh. Crossbred cows (n=90) those already completed third lactations, were selected randomly from three different dairy farms (e.g. Jarip, Mullah and Nahar) located in Chittagong, Bangladesh. ...

Genetic Divergence in Component Strains of Karan-fries Cattle

Immunological attributes of blood and milk neutrophils isolated from crossbred cows during different physiological conditions

The goal of this work was to understand how polymorphonuclear leukocytes (PMN), the first line of cellular defence, integrate and prioritize multiple chemotactic signals to navigate during periods of demand like subclinical mastitis (SCM), clinical mastitis (CM), pregnancy (P), and calving (C). For this, blood and milk samples were collected from five groups of crossbred cows (healthy, with SCM...
