Abstract
The improving of the level of fertilazing of the sheep has a great importance in people's nutrition and the contribution of the countries economy. For this aim, this investigation was done to prove the -applicability of the system of lambing in Ramht; sheep three times in two years. The sheep were mated in 8-month intervals consisting of 5-month pregnancy, 2-month lactation and one-month resting periods. It has been found that while fertility traits such as oestrus, pregnancy, partrution, rate of lamb, twinnig and litter size were 97. 97 %, 87. 37 %, 86.86 %, 117.1 7 %, 34.38% and 1.34 respectively in october; 90.27%, 65.40 %, 65.40 %, 75.67%, 15.7 % and 1.16 respectively in July, the values of the same fertility traits were 75.43%, 75.43%, 75.43%, 77. 20 %, 2.32% and 1.02 respectively in April. During the investigating, it has been found that the average lambing interval was 281 days. It has been found that the birth weight and 60th day- weight of male lambs from mating in October were 3.99 and 15.23 kg, the values ofthe same traits of the female Lambs 3.63 and 14.89 kg; the birth weight of the male and female lambs mating in July was 3.94 and 3. 78 kg and 6Qih day weight 17.42 and 16.65 kg; the values of the same traits of the male and female ones in April were 4.85 and 4.67 kg, 15.32 and 15.27 kg. respectively. The survival on 60th day of the lambs, which were born after mating in October, July and April has been established as 95.25, 97.86 and 92.04 % respectively. The general average values of the body weights of ewe before mating were 60.41, 60.68 ve 57. 62 kg respectively in mating in October, July and April. When the research is completely considered, it was concluded that programe of lambing three times in two years would be able to succesfully apply to the Ratrilzy Sheep.
Koyunculugun, halkın beslenmesine ve ülke ekonomisine katkısının artırılmasında, döl verimi duzeyinin geliştirilmesi ayrı bir önem taşımaktadır. Bu amaçla, Ramlıç; koyunlarda 2 yılda 3 kuzulatma sisteminin uygulanabilirligini araştırmak için bu çalışma yapılmıştır. Koyunlar 5 ay gebelik, 2 ay laktasyon ve 1 ay dinlenme periyodundan oluşan 8 ay aralıklarla tohumlanmışlardır.
