  This study was made to determine the effect of cage stocking density on growth, feed consumption and, slaughter and carcass characteristics of rock partridges (A. Graeca). In the study, 135 rock partridge chicks at 4 weeks of age were separated into 3 different placing groups (Two sub groups of 25, two subgroups of 20 and three subgroups of 15 partidges). Group I was gathered in an area of 25 partridges/m2, Group II in an area of 20 partridges/m2 and Group III in an area of 15 partridges/m2. As a result, in Groups I, II and III, partridge weights were found to be 453.06, 446.04 and 444.36 g, feed benefit ratios were 5.84, 6.26 and 6.10; life strength values were 92.00%, 95.00% and 91.11%; carcass output were 72.11%, 72.42% and 73.68%, respectively . The differences between the groups were not statistically significant. Cage stocking density was there fore observed not to have an effect on these parameters.

  In this study, it was aimed to determine the effects of high temperature on the live weight, food consumption, taking benefit from the food, living strength, some carcass characteristics and the respective effects on the living strength. By this purpose, 584 quails at the age of 1 week were separated into two groups; one of the groups was identified as the control group to be placed under variable temperature (18-24oC), and the other group (trial group) was kept under 35oC. As a result of the research, the differences between the control and trial groups regarding to the live weight, carcass weight and carcass productivity, food consumption and the values of taking benefit from the food were found significant. (P< 0.05, P< 0.01). Depending on the higher temperatures, some decreases were found in the live weight, food consumption and the values of taking benefit from the food, living strength.

  This study was conducted with the aim of comparing wool production characteristics of Morkaraman, Chios x Morkaraman (F1) and kivircik x Morkaraman (F1) crossbreds. The study population consisted of 25 Morkaraman , Chios x Akkaraman (F1) and Kivircik x Morkaraman (F1) female cross-breeds, at first shearing (1 ?) time. Dirty wool production values were 2.200 , 1.160 and 1.370 kg (P<0.001); staple length values were 15.525 , 10.517 and 11.955 cm (P<0.001) ; fiber diameter values were 36.716 , 33.170 and 31.897 (P<0.01); tenacity values were measured as 15.029 , 9.528 and 10.333 g (P<0.001) and elongation values were 34.858% , 30.789% and 33.184% (P<0.01) in Morkaraman, Chios x Akkaraman (F1) and Kivircik x Morkaraman (F1) genotypes, respectively. In all of these characteristics evaluated in the present study, Morkaramans showed the greatest values when compared to both crossbred groups. However, Morkaramans did not have any significant superiority in elongation values when compared to Kivircik x Morkaraman crossbreds (F1). Based on the results of this study, we might suggest that the rough and mixed wool of Morkaramans and their F1 crossbreds can be used for carpet and rug industry, and handmade textile in local facilities and wool of crossbreds might be suitable for fabric industry.

  In this study, the effects of storage period of rock partridge eggs on hatchability characteristics and embryonic deaths were examined. In the study, a total number of 752 eggs which were obtained from a herd of rock partridges at 41 weeks of age were used. In different storage periods (1-14 days), no significant effect of storage period on hatchability performances of the partridge eggs was observed. Long storage time did not affect the hatchability of partridge eggs. It was observed that embryonic deaths in late period were more (not statistically significant) than early or medium periods. The least embryonic deaths were observed at early periods. As a result, it can be stated that, 14 days of partridge egg storage have no negative effect on hatchability results.
