Received: Revised: Accepted: Published online: September 16, 2016 January 05, 2017 February 04, 2017 March 11, 2017 Body condition score (BCS) changes and non-esterified fatty acids (NEFA) are good indicators for measuring lipomobilization during the transition period. The aim of this study was to establish the possible correlation between cows with a higher BCS during this period and their rep...

The hypothesis of the present study is that active immunization of cows against inhibin would neutralize endogenous inhibin, increase circulating levels of follicle stimulating hormone, and subsequently affect follicular dynamics and the ovulation rate during the estrous cycle. Thirteen cows were immunized against inhibin alpha-subunit and, 6 cows were immunized with a placebo. Both groups were...

Subclinical mastitis is considered as one of the most prevalent diseases in dairy cows, causing drasticloss in the dairy industry. Oxidative stress, induced by reactive oxygen species (ROS), is believed to be aprimary factor in various cattle diseases including mastitis, but there are few studies regarding the role ofROS in subclinical mastitis. This study was undertaken to i) study the changes...

Djoković R., H. Šamanc, Z. Nikolić, S. Bošković Bogosavljević: Changes in Blood Values of Glucose, Insulin and Inorganic Phosphorus in Healthy and Ketotic Dairy Cows after Intravenous Infusion of Propionate Solution. Acta Vet. Brno 2007, 76: 533-539. The aim of the present study was to determine the degree of blood glucose utilization by peripheral tissue on the basis of changes in blood concen...

The objective of this experiment was to compare metabolic and milk production parameters in dairy cows supplemented and nonsupplemented with rumen-protected choline (RPC) during the transition period. Twenty-three nonlactating, multiparous, pregnant Holstein cows were ranked by BW and BCS 21 d before expected date of calving and immediately were assigned to receive (n = 12) or not receive (cont...

The current study aimed to evaluate serology, and isolate and genotype Toxoplasma gondii strains from pregnant dairy cows, slaughtered in an abattoir for human consumption, and their fetuses. Blood from 60 pregnant dairy cows and blood and tissue samples (brain, lung, heart, and liver) from their fetuses were collected and analyzed in a mouse bioassay. Antibodies against T. gondii were observed...

The aim of this trial was to determine whether the selenium status of suckling calves could be improved by supplementing their dams' diet with organic Se instead of sodium selenite. A herd of 103 Hereford cows, which were on grass paddocks all year round, was divided into two groups. Both groups had free access to a mineral supplement that contained 30 mg of Se/kg; for one group the source of t...

Blood samples were collected from 1328 dairy cows of different parities in 46 herds in two regions of South Korea and tested for bovine viral diarrhoea virus (BVDV) by reverse transcriptase-PCR (RT-PCR) for the detection of viral sequences in whole blood and by a commercial elisa for the detection of bvdv-specific antibodies. None of the animals was positive by RT-PCR but 770 (58 per cent) were...
