Abstract

SUMMARY A Study on the Comparison of Sakız, Kivi rcı k and Dağlıç Sheep for Production Characteristics in Semi-Intensive Conditions This study was carried out at Bandırma Sheep Breeding Rese arch Institute to investigate some poduction characteristics of Kıvırcık, Sakız and Dağlıç breeds in semi-intensive condition and to compare genotypes in respect to production traits. For the reproduction traits such as oestrus, pregnancy, birth, lamb production and twin birth rates and lamb number per birth were 96.0 %, 78.0 %, 76.0 %, 88.0 X.15.7 % and 1.15 in Kı vırcık; 100 %, 45.8 %, 41.6 %, 91.6 %, 90.0 % and 2.20 in Sakız; 93.4 %, 73.9 %, 73.9 %, 76.0 %, 2.9 % and 1.03 in Dağlıç geno types respectively. Corrected weights at birth, 60 th day, 105 th day (weaning) and 180 th day were 4.24, 17.18, 27.36 and 36.26 kg in Kıvırcık; 3.02, 1.4.22, 24.75 and 35,42 kg in Sakız ; 3.31,13.56, 22.70 and 31.60 kg in Dağlıç, respectively. Survival rate of lambs on 105 th and 180 th day were determined 86.3 % and 86.3 % in Kıvırcık; 50.0 % and 50.0 % in Sakız; 85.3 % and 85.3 % in Dağlıç groups.

SUMMARY A Study on the Comparison of Sakız, Kivi rcı k and Dağlıç Sheep for Production Characteristics in Semi-Intensive Conditions This study was carried out at Bandırma Sheep Breeding Rese arch Institute to investigate some poduction characteristics of Kıvırcık, Sakız and Dağlıç breeds in semi-intensive condition and to compare genotypes in respect to production traits. For the reproduction traits such as oestrus, pregnancy, birth, lamb production and twin birth rates and lamb number per birth were 96.0 %, 78.0 %, 76.0 %, 88.0 X.15.7 % and 1.15 in Kı vırcık; 100 %, 45.8 %, 41.6 %, 91.6 %, 90.0 % and 2.20 in Sakız; 93.4 %, 73.9 %, 73.9 %, 76.0 %, 2.9 % and 1.03 in Dağlıç geno types respectively. Corrected weights at birth, 60 th day, 105 th day (weaning) and 180 th day were 4.24, 17.18, 27.36 and 36.26 kg in Kıvırcık; 3.02, 1.4.22, 24.75 and 35,42 kg in Sakız ; 3.31,13.56, 22.70 and 31.60 kg in Dağlıç, respectively. Survival rate of lambs on 105 th and 180 th day were determined 86.3 % and 86.3 % in Kıvırcık; 50.0 % and 50.0 % in Sakız; 85.3 % and 85.3 % in Dağlıç groups. Lactation milk production and lactation period of Kıvırcık, Key Words : Sakız Sheep, Kıvırcık Sheep, Dağlıç Sheep, Production CharacteristicsSakız and Dağlıç groups were 76.92 kg and 157.17 ± 6.87 days ; 103.86 kg and 219.33 ± 11.16 days and 57.06 kg and 169.37 ± 7.86 days respectively. After shearıng and before breeding body weight of Kıvırcık, Sakız and Dağlıç genotypes were found 49.44 and 51.07 kg; 51.39 and 52.71 kg; 46.13 and 46.04 kg respectively. Dirty fleece weight, fiber length, fiber diameter, kemp fibers rate and medullated fibers rate were 2.21 kg, 9.65 cm, 26.83 tnicron, 0.0 % and 3.79 % in Kıvırcık ; 2.08 kg, 9.94 cm, 23.77 micron, 0.06 % and 1.32 % in Sakız ; 2.57 kg, 14.85 cm, 27.16 micron, 0.89 % and 7.90 % in Dağlıç groups, respectively. Except lactation mi l k production, genotype effects on birth weight, 60 th, 105 th and 180 th day body weight, after shearing and before breeding body weight, dirty fleece weight and wool characteristics were found stat istically signifıcant (P<0.05- P<0.01-P<0.001). Effect of the ewe age were not signifıcant for ali the traits. Sex and birth type were significantly affected on birth, 60 th, 105 th and 180 th body weights (P<0.05-P<0.01- P<0.001). it was concluded that the performance of the Kıvırcık was good and Dağlıç was showed nearly the same performance as its orginal performance. Sakız had lower reproduction performance and survival rate this breed was not found appropriate for Ban¬ dırma conditions. The result of this study wi11 show that which loca! sheep breed will be rared in the Research Farm and which öne will be useful for crossing with important sheep breeds. 4
