Production Losses Due To Endemic Foot-And-Mouth Disease In Cattle In Turkey, Berri̇n Şentürk, Cengi̇z Yalçin Jan 2008

Production Losses Due To Endemic Foot-And-Mouth Disease In Cattle In Turkey, Berri̇n Şentürk, Cengi̇z Yalçin

Turkish Journal of Veterinary & Animal Sciences

This research paper is aimed at estimating foot-and-mouth disease (FMD)-induced production losses in individual dairy and fattening cattle in Turkey. The data used were obtained from a Delphi Expert Opinion Survey. The weighted average FMD-induced financial losses for all breeds were estimated to be $294/head for a milking cow, $152/head for a dairy heifer and $197/head for beef cattle. However, the amount of financial loss varied across different breeds, ages, and sexes. The study findings suggest that culling Holstein breed cows, beef cattle, and Holstein and cross breed female calves, as soon as they have an FMD infection, would be …

The Effect Of Duration Of Finishing Period On The Performance, Slaughter, Carcass, And Beef Quality Characteristics Of Eastern Anatolian Red Bulls, Abdülkadi̇r Özlütürk, Nuri̇ni̇sa Esenbuğa, Mete Yanar, Necdet Ünlü, Muhli̇s Maci̇t, Si̇nan Kopuzlu

Turkish Journal of Veterinary & Animal Sciences

Seventeen Eastern Anatolian Red (EAR) bulls at 20 months of age were divided into 2 treatment groups and fed for either 168 days (S) or 210 days (L). Initial and final weights were not significantly different. While bulls in the L group had the highest total weight gain (149.0 vs. 177.2 kg), feed efficiency ratio was superior for the cattle fed for 168 days. Carcass weight, spleen and front + hind feet weights as a percentage of slaughter weight, weight of kidney fat, percentage of kidney, pelvic, and heart fat, and yield grade all increased (P < 0.05) with feeding time. Bulls in the L group received a higher (P < 0.05) panel rating for juiciness, and the panel juiciness score was closely associated with tenderness measurements such as panel tenderness score, Warner Bratzler shear force value, and number of chews before swallowing. It is concluded that duration of finishing significantly influenced carcass, slaughter, and organoleptic beef quality traits of young EAR bulls.

Noteworthy Record Of The Mediterranean Water Shrew (Neomys Anomalus) From South-Western Iran (Mammalia: Soricomorpha), Hamid Reza Esmaeili, Ghorbanali Gholamhosseini, Azad Teimory, Boris Krystufek Jan 2008

Noteworthy Record Of The Mediterranean Water Shrew (Neomys Anomalus) From South-Western Iran (Mammalia: Soricomorpha), Hamid Reza Esmaeili, Ghorbanali Gholamhosseini, Azad Teimory, Boris Krystufek

Turkish Journal of Zoology

Three water shrew specimens were collected in the Sheshpir spring (2303 m a.s.l.), Fars province, south-western Iran. In pennial morphology, which is species-specific in the genus Neomys Kaup, 1829, the specimens were indistinguishable from N. anomalus Cabrera, 1907. The Sheshpir spring is located approximately 900 km to the south-south-west of Gorgan, the only site in Iran where N. anomalus has been known to occur so far. The spring is a stony basin with bare banks and poorly developed aquatic vegetation and as such is an atypical habitat for water shrews. It is noteworthy that fish are absent in the spring.
