The Effects Of Cadmium On Levels Of Glucose In Serum And Glycogen Reserves In The Liver And Muscle Tissues Of Cyprinus Carpio (L., 1758), Bedi̇i̇ Ci̇ci̇k, Kenan Engi̇n

Turkish Journal of Veterinary & Animal Sciences

The common carp (Cyprinus carpio L., 1758) was exposed to sublethal concentrations of cadmium (0.05, 0.1, 0.5 and 1.0 mgl^{-1}) for 10 days. The levels of serum glucose and glycogen reserves in the liver and muscle tissues were measured both in fish exposed and not exposed to Cd. The levels of glycogen reserves in the liver and muscle tissues were significantly (P < 0.05) decreased in fish exposed to sublethal concentrations of Cd compared with the levels measured in the control groups. The decrease in glycogen levels in the liver and muscle tissues under the highest metal concentration (1.0 mgl^{-1}) were 24% and 29%, respectively. The blood serum glucose levels of fish exposed to Cd were significantly (P < 0.05) increased compared with the levels measured in the control groups. This increase was correlated with the increase in water Cd concentrations.

Altering The Lactation Cycle: Is A 60-Day Dry Period Too Long?, Mehmet Şükrü Gülay Jan 2005

Altering The Lactation Cycle: Is A 60-Day Dry Period Too Long?, Mehmet Şükrü Gülay

Turkish Journal of Veterinary & Animal Sciences

The most critical problem for the evaluation of different dry period lengths is the relationship between days dry and subsequent milk production. It is assumed that when a cow is dried off, the loss in the current lactation will be compensated for by greater milk production during the following lactation. However, the process of parturition and initiation of lactation are extremely important events and they are associated with many problems that may result in removal of the individual cow from the herd or in greatly reduced milk production, especially early in the lactation. Therefore, identification of the shortest possible dry …

The Effect Of Mad Cow (Bse) Scare On Beef Demand And Sales Loss: The Case Of İzmir, Bülent Mi̇ran, Sedef Akgüngör Jan 2005

The Effect Of Mad Cow (Bse) Scare On Beef Demand And Sales Loss: The Case Of İzmir, Bülent Mi̇ran, Sedef Akgüngör

Turkish Journal of Veterinary & Animal Sciences

This paper investigates the effect of the BSE scare on beef consumption due to the intense media coverage. Using monthly data, a beef demand model for January 1995-February 1997 period is estimated for İzmir Province. Beef sales dropped immediately after the media coverage on BSE in April 1996 and continued through June 1996 when the intense media coverage stopped. The econometric model reveals that beef sales in İzmir would have been 36.4% higher if the BSE crisis never occurred. The annual individual willingness to pay is $0.5224 per year to avoid consuming BSE contaminated meat.
