Protein supplementation is costly and can result in excess nitrogen (N) excretion. The objective of this study was to evaluate the effects of feeding different levels of dietary protein on average dai...
The objectives were to determine the effects of insemination with sexed semen at spontaneous and induced estrus, fixed-time insemination at synchronized estrus, the deposition site, estrous intensity,...
The objective of this study was to investigate the effects of reducing dietary phosphorus (P) on the frame size, udder traits, blood parameters and nutrient digestibility coefficient in 8- to 10-month...
The present study evaluated the effects of different cutting height on nutritive value, fermentation quality, in vitro and in vivo digestibility of whole crop barley silage. Whole crop barley forage (...
Freemartinism, a primary disorder of sex development (DSD) in cattle, is associated with leukocyte chimerism (60,XX/60,XY). The diagnosis of DSD is easy if it is known that a heifer with abnormally de...
The aim of this study was to estimate potential relationships between insulin-like growth factor I gene polymorphisms (IGF1/TasI and IGF1/SnaBI) and the growth parameters of calves as well as their su...
Economical and ecological issues as well as consumer demand for sustainably produced agricultural food rise the trends to fatten beef cattle on pasture during the grazing season. However, particularly...
Older animals were generally fatter and their carcasses contained lower proportions of high-priced meat (P < 0.01) and bones (P < 0.05). Bulls exhibited lower contents of dry matter (P < 0...
The objective of this study was to develop a superovulatory program based on synchronization of follicular waves with GnRH which could be applied regardless of the stage of the oestrous cycle. 36 heif...
The objective of this study was to develop a superovulatory program based on the synchronization of follicular waves with GnRH which could be applied regardless of the stage of the oestrous cycle. In ...
Differences in follicular development and repeatability of follicular growth pattern among Czech Fleckvieh (n = 20) and Holstein (n = 23) heifers were investigated. Follicular dynamics was evaluated b...
The objective of the study was to determine the effect of growth and development intensity in Holstein replacement heifers on economically important animal traits. The intensity of growth was assessed...
All isolates except for the CNS group exhibited strongly elevated SCC (> 1 × 106 cells/ml). However, the coagulase-negative Staphylococci did not have a distinct pattern with respect to SCCs. The...
Mastitis is an important cause of early culling of dairy heifers. The aims of this study were to identify microorganisms that cause subclinical mastitis (SCM) in Holstein heifers in northern Jordan, t...
The aim of this study was to evaluate the effect of intrafollicular treatment (IFT) with different doses of luteinising hormone. Experimental heifers were treated with a single deslorelin implant to d...
