Genetic Parameters of Production and Reproduction Traits and Factors affecting it in Frieswal Cattle

International Journal of Livestock Research, 2017
Data on performance records of 1249 Frieswal daughters of 71 sires over a period of 13 years from 2000-2012 were analyzed to determine the effects of farm, parity, type of calving, period of birth and season of birth on lactation length (LL), 305-day milk yield (305-DY) and calving interval (CI).

Analysis of beta-casein gene (CSN2) polymorphism in Tharparkar and Frieswal cattle

Indian Journal of Animal Research, 2019
A1 and A2 are most frequently observed Beta-Casein variants in dairy cattle. A1 â-casein on digestion releases an opioid, BCM-7 which has been found significantly associated with type 1 diabetes mellitus (DM-1), ischemic heart disease (IHD), autism and including other immune suppression activities in man.

Factors affecting first lactation cumulative monthlymilk yields in Frieswal cattle

Indian Journal of Animal Research, 2016
A study was conducted to analyse the effect of various factors on cumulative monthly milk yields in Frieswal cows at Military Dairy Farm, Meerut, over a period of eight years (2006-2013). A total of 441 part lactation records of cows born to 30 Frieswal sires were analyzed using the SAS (2002) software.

Genotypic profiling of coding region of leptin gene and their association studies on reproductive and milk production traits in Sahiwal and Frieswal cattle of India

African Journal of Biotechnology, 2013
Leptin gene has its role in appetite, metabolism, growth and milk production in cattle. Single nucleotide polymorphisms (SNPs) in leptin gene in different cattle breeds have been reported and subsequently associated with their production performance. The objective of this study was to evaluate the association of genetic differences in the bovine leptin

Balancing production and reproduction traits in frieswal cattle: a multivariate approach

Agriculture Association of Textile Chemical and Critical Reviews
This study aimed to estimate breeding values, selection differentials, and response to selection for production and reproduction traits in Frieswal cattle. Data on 1,163 progeny records sired by 69 sires over nine years were collected and analyzed using Average Information Restricted Maximum Likelihood (AI-REML) and principal component analysis (PCA ...

Comparative CpG methylation kinetic patterns of cis-regulatory regions of heat stress–related genes in Sahiwal and Frieswal cattle upon persistent heat stress

International Journal of Biometeorology, 2021
The kinetic patterns of CpG methylation of the cis-regulatory region of heat stress-related genes on exposed to heat stress (at 42 °C) between the Sahiwal and Frieswal cattle was compared in the present study. Using an in vitro whole blood culture model, cells were continuously exposed to heat stress (at 42 °C) for 6 h. Methylation levels of five genes,

Promoter variants at AP2 box region of Hsp70.1 affect thermal stress response and milk production traits in Frieswal cross bred cattle

Gene, 2013
Heat shock proteins (Hsp) are known to play major role in protection of cells from thermal stress. Nucleotide polymorphisms within the promoter of Hsp affect degree of expression and inducibility of Hsp mRNA. The present study aimed to investigate the effect of polymorphism within promoter region on the cellular expression of Hsp70.1 mRNA and ...

Risk factors associated with abnormal parturition and their effects on production and reproductive performance in Frieswal cattle of India

Indian Journal of Animal Research, 2016
Records of 1024 Frieswal cows maintained at the Military Farm, Meerut, India over a period of 20 years from 1989 to 2008, sired by 91 bulls were included in the present study to assess the incidence and risk factors associated with abnormal parturition like dystocia, stillbirth, premature birth and abortion.

Effect of heat stress on the expression profile of Hsp90 among Sahiwal (Bos indicus) and Frieswal (Bos indicus×Bos taurus) breed of cattle: A comparative study

Gene, 2014
We evaluated the effect of thermal challenge on the expression profile of heat shock protein 90 (Hsp90) among Sahiwal (Bos indicus) and Frieswal (Bos indicus × Bos taurus) breeds of cattle. The present investigation was focused on the comparative studies on Hsp90 expression among Frieswal and Sahiwal under in vitro and environmental heat stress ...
