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

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.

Turkish Journal of Veterinary & Animal Sciences

Wheat straw, barley straw, alfalfa hay, alfalfa silage and maize silage were offered ad libitum to three male sheep, and daily dry matter intake (DMI) and apparent dry matter digestibility (DMD) were measured. Samples of forages were incubated with rumen fluid to determine gas production. Gas productions were measured at 3, 6, 12, 24, 48, 72 and 96, and gas production constants (a, b, c,) were described using the equation y = a + b (1 - e-^{ct}). Gas production at all incubation times and gas production constants (c, b and a+b) were significantly (P < 0.001) correlated to DMD or DMI. Although the gas production constant c explained 74% of the variation of DMD, the gas production constant b explained 92% of the variation of DMD. The gas production constants c and (a+b) in combination explained 96% of the variation of DMD. The gas production constants b and c alone explained 70% and 78% of the variation of DMI respectively. The gas production constants in combination explained 84-90% of the variation of DMI. It was concluded that the accuracy of predicting DMD or DMI can be increased when gas production constants are used in combination, and the in vitro gas production technique has good potentiality to predict DMD and DMI.

Semen (via an artificial vagina) and blood were collected five times during the breeding season from a total of 10 mature and healthy fat-tailed rams (Akkaraman and Awassi) in Afyonkarahisar. Breed effects were significant for relative testes volume, sperm concentration, percentage of abnormal spermatozoa, triiodothyronine (T_{3}), albumin/globulin ratio, total lipid (P < 0.05) and cholesterol (P < 0.01). Some reproductive parameters and biochemical properties of Akkaraman and İvesi rams indicated that the values were recorded in the optimum range during the breeding season under Afyonkarahisar conditions. In addition, some reproductive parameters of rams show a correlation with some biochemical and enzymatic properties.
