Conjugated Linoleic Acid: Chemical Structure, Sources And Biological Properties, Rahi̇m Aydin

Turkish Journal of Veterinary & Animal Sciences

Conjugated linoleic acid (CLA) is a group of geometrical and positional isomers of linoleic acid (C18:2, cis-9, cis-12). In contrast to linoleic acid, double bonds in CLA are usually located at positions 9 and 11 or 10 and 12 and each double bond can be either in the cis or trans configuration. Meat and dairy products from ruminant animals (such as milk, butter, yogurt and cheese) are the principal natural sources of CLA in the human diet. Egg and meat products from poultry contain less CLA than meat from ruminant animals (0.6 and 0.9 mg/g fat vs. 2.9 to 5.6 …

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 …

Investigation Of The Selectivity Parameters For Carp (Cyprinus Carpio Linnaeus, 1758) In Seyhan Dam Lake, Caner Enver Özyurt, Dursun Avşar Jan 2005

Investigation Of The Selectivity Parameters For Carp (Cyprinus Carpio Linnaeus, 1758) In Seyhan Dam Lake, Caner Enver Özyurt, Dursun Avşar

Turkish Journal of Veterinary & Animal Sciences

Selectivity studies are very important for sustainable fisheries. Therefore, in this study, selectivity parameters for the carp in Seyhan Dam Lake were estimated using gill nets having a mesh size of 28, 32, 40 and 45 mm. Gill nets used in pikeperch fishing of mesh size of 28, 30 and 32 mm could cause growth in the overfishing of carp. Therefore, it is recommended that longline fishing should be commonly used instead of gill nets on pikeperch fishing. Consequently gill nets having minimum 50 mm mesh size can be used for carp fishing in Seyhan Dam Lake.

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.
