Milk urea nitrogen (MUN) of dairy cows was determined in relation to breed. A total of forty (40) Pabna and red Chittagong dairy cattle each of twenty (20) were selected to know the milk composition, nutritional status and milk urea nitrogen. Live weight of Pabna Cattle (187±14 kg) was higher than that of red Chittagong cattle (174±4 kg). In Pabna cattle milk yield (4.94 kg), minerals (0.15%) a...
The main objectives of this study were to determine the occurrence and potential causative factors of Immune-mediated hemolytic anemia (IMHA) in native cattle and water buffaloes from southwest of Iran. Fifty-three anemic animals (37 cattle and 16 buffaloes) were studied. A full clinical history and physical examinations were undertaken for all animals. Four clinically healthy cattle and four h...
New Zealand’s beef industry produces approximately 580,000 tonnes of beef per year, about 80% of which is exported, with approximately 70% of this beef destined for the North American manufacturing market. Around 65% of beef cattle originate from the dairy industry. Beef cows produce 1.1 million calves (killed as heifers or steers) per year for the prime beef market. In addition, 0.4 to 0.6 mil...
Records of 594 calving dates and 493 calving intervals collected from a herd of Retinta beef cows in southwest Spain were studied. Their efficacy as reproductive measures were compared when a long breeding season was utilized. Variables used were date of present calving (DOC), date of subsequent calving (DOSC), time from start of breeding season to calving (TBSC), interval to next calving (CI),...
the purpose of this study was to determine the socio-economic and intellectual factors affecting the imported meat preferences of consumers and to reveal the personal prioritized preferences of buyers consuming domestic meat and imported meat. the study was carried out in izmir, the third city of turkey, where face-to-face interviews were conducted in 300householdswhose occupants shop at hyperm...
The aim of this study was to evaluate the Bali cattle genetic diversity and hybrid cattle using microsatellite markers. Blood samples (n=192) were collected from various cattle breed, i.e. Bali (n=96), Madura (n=48), and Peranakan Ongole (PO) Kebumen (n=48). The microsatellite locus used for assessing the genetic variation was INRA035, ILSTS006, ETH225, and HEL9, while the genetic profile was d...
Background: Species identification in commercially processed food and feed products is one of the important issues. This study was conducted to develop a genetic method for the detection of pig and cattle species in processed food and feed products using newly designed species-specific primers targeting mitochondrial 12S rRNA gene fragments. Methods: Two sets of specific primers were designed ...
Changes in performance traits in beef cattle over the last 30 yr necessitate the re-evaluation of central testing procedures to ensure that they are cost effective and appropriate for current test objectives. The objective of this study was to evaluate the potential for reducing the length of evaluation from 140 d to either 112 or 84 d. Data evaluated were postweaning feedlot performance test r...
Neospora caninum is a worldwide distributed pathogen which causes abortion in cattle leading to economic loss in the cattle industry. The aim of this study was to determine the seroprevalence of N. caninum antibodies in the native cattle slaughtered in various areas of Kurdistan province (western Iran) from September 2010 to September 2011. Serum samples from 368 cattle slaugh...
Abstract: In order to investigate the seroprevalence of Neospora caninum infection in cattle in Southwestern Iran, blood samples were collected from Holstein (121 animals) and cross-breed (436 animals) cattle from three farms and seven areas of Ahvaz, respectively. All of the Holstein cattle were “4 years old but cross-breed cattle were from different age groups ( < 2, 2-4, 5-6 and > 6 years ol...
