FOR FULL BIO CLICK HERE Welcome to the seventh issue of Sheep and Beef Research Review. The content in this issue is split evenly between the ovines and bovines. Ovine highlights include clinical and sub-clinical mastitis and the nutritional management of lactating ewes while bovine highlights include sustained internal parasite control in beef heifers and the importance of colostrum for neonat...

Gunay A., U. Gunay: Effects of Clinical Mastitis on Reproductive Performance in Holstein Cows. Acta Vet. Brno 2008, 77: 555-560. The objective of this study was to determine the effects of clinical mastitis on reproductive performance in 135 early lactation cows. The animals were divided into two groups according to the occurrence of mastitis as follows: group I (n = 45), clinical mastitis prio...

The first member ofthe group ofpleuropneumonia organisms was isolated by Nocard and Roux in 1898 from cases ofcontagious pleuropneumonia of cattle, a disease in which the essential pathological lesions are gross pulmonary cedema, pleural exudate, and arthritis. A similar organism was found by Bridre and Donatien (1923, 1925) in sheep and goats suffering from agalactia, a syndrome which includes...

Contagious agalactia is an infectious syndrome of sheep that is characterized by mastitis with reduction of milk production, arthritis, abortion, and keratoconjunctivitis. The disease is rapidly spread by the contact of the infected animals with the healthy ones. Domestic sheep and goats of both sexes can be infected at an equivalent frequency. Most of the researchers use culture and molecular ...

mastitis, arthritis, keratoconjunctivitis and, occasionally, abortion. Mycoplasma agalactiae (Ma) is the main cause of the disease in sheep and goats, but M. capricolum subsp. capricolum (Mcc), M. mycoides subsp. capri (Mmc) and M. putrefaciens produce a clinically similar disease, more often in goats, which may be accompanied by pneumonia. Ma and Mcc have been isolated from wild small ruminant...

the present study aimed to estimate the effects of parity, calving season and year of calving on the prevalence of subclinical mastitis in holstein cows. a total of 2682 records from 869 holstein cows in a large dairy farm (azarbaijan province, iran), respecting the period from 2006 to 2009, were collected. data was analyzed using proc mixed of sas software by mivque method. subclinical mastiti...

Q fever is a zoonosis caused by infection with Coxiella burnetii. Although the reservoir of C. burnetii consists of various species, the most common sources of human infection are farm animals, such as cattle, goats, and sheep. The agent is typically transmitted by the aerosol route, and in more than half of the cases primary infection is symptomless. Clinical outcomes of C. burnetii infection ...

Visna/Maedi virus (VMV), a small ruminant lentivirus responsible for lymphoproliferative pneumonia, encephalitis, arthritis and/or mastitis in sheep, has been detected in different non-lymphoid organs. However, only a few investigations have been carried out in lymphoid tissues. In this study, some lymphoid tissues and lymph node draining or non-draining VMV target organs from five sheep infect...
