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

Genetic analysis of milk production efficiency traits in Jersey crossbred cattle

“…These estimates were in accordance with the estimates obtained by Singh and Gurnani (2004) and Singh et al (2005). However, Haile et al (2009) in Ethiopian Boran cattle and Saha et al (2010) in Karan Fries cattle reported lower heritability estimates as compared to the present findings.…”

“…TMY/LL and TMY/CI in present study. Similar results were observed by Singh and Gurnani (2004) and Verma and Thakur (2013) in crossbred cattle. This suggests that superior sires can be used effectively to improve milk production efficiency traits in crossbred cattle.…”

“…Singh and Gurnani (2004), Singh et al (2005), Lakshmi et al (2010) and Japheth et al (2015) also reported significant effect of period of calving on milk production efficiency traits in crossbred cattle. On contrary, Verma and Thakur (2013) reported non-significant effect of period of calving in Red Sindhi × Jersey cattle.…”

Profiling of urinary proteins in Karan Fries cows reveals more than 1550 proteins

“…The aim of the present study was to profile the urinary proteome of Karan Fries cows, a crossbred cattle of Holstein Friesian male (Bos taurus) × Tharparker (Bos indicus) female. The Karan Fries breed has adapted well to tropical climate and plays important role in milk production in India [14,15]. In this proteomic study, a combination of extraction procedures was used to isolate urinary proteins from Karan Fries cows and characterized by LC-MS/MS leading to the identification of a total of 1564 proteins.…”

Disposal Pattern of Cattle Calves Born through Embryo Transfer Technology

“…In order to compare with conventional programme of breeding animals, literature scanning revealed similar reasons of culling on body defects and reproductive problems 20,21,22,23 . In cows the main reasons for disposal is related to udder problems and below farm standards.Various subfertility traits like poor libido and unacceptable seminal profile were found to be the significant reasons (p<0.01) for culling of the breeding bull.…”
