Abstract
Bu çalışma broiler piliçlerde başlangıç yeminden büyütme yemine, büyütme yeminden bitirme yemine geçiş zamanlarının besi performansı üzerine etkisini incelemek amacıyla yapılmıştır. Denemede bir günlük 2000 broiler civciv (Avion Form) her bir grupta 250 civciv olacak şekilde 8 gruba rastgele yerleştirilmiştir. Civcivlere deneme süresince sürekli aydınlatma sağlanmıştır. Denemede % 23.23 protein ve 3061 kcal/kg ME’li başlangıç, %19.80 protein ve 311 7 kcal/kg ME'li büyütme ve % 19. 00 protein ve 31./6 kcal/kg ME içeren bitirme yemi kullanılmıştır. Denemede kullanılan başlangıç, büyütme ve bitirme yemleri sırasıyla l. gruba; 1-7, 8-35 ve 36-42 günler, 2. gruba; 1-14, 15-35 ve 36-42 günler, 3. gruba; 1-21, 22-35 ve 36-42 günler, 4. gruba; 1-7, 8-28 ve 29-42 günler, 5. gruba; 1-7, 8-14 ve 15-42 günler, 6. gruba; ! -7, 8-21 ve 22-42 günlerde verilmiştir. 7. ve 8. gruplarda başlangıç ve büyütme yemleri sırasıyla 1-14 ve 15-42, 1-21 ve 22-42 günlerde verilmiştir. Birinci hafta başlangıç yemi ile beslenen tüm gruplarda canlı ağırlıklar arasındaki farklar önemli bulunmamıştır. Ancak sonraki haftalarda canlı ağırlık yönünden gruplar arası farklar önemli bulunmuştur (P < 0.05- P < O. O 1). İkinci haftadan itibaren en yüksek canlı ağırlık 2. grupta tespit edilmiştir. 42 günlük kesim yaşında yemden yararlanma değerleri 1.88 ile 2.10 arasında bulunmuştur. En iyi yemden yararlanma 2. grupta saptanmıştır. Bu çalışmanın sonuçları na göre broiler performansının, başlangıç yeminden büyütme yemine geçiş zamanından önemli ölçüde etkilediği ve büyütme yeminden bitirme yemine geçiş zamanının etkisinin önemli olmadığı belirlenmiştir. Broylerlerde başlangıç, büyütme ve bitirme yemleri için en uygun yemierde zamanının sırasıyla 1-14, 15-35 ve 36-42 günler olduğu sonucuna varılmıştır.
This study was conducted to examine the effects of transition periods of the diet from starter to grower and from grower to finisher diet on the fattening performance of broiler chickens. In the experiment, one-day-old, 2000 chickens (Avian Farm) were randomly allocated into 8 groups, each composed of 250 chickens. A continuous lighting was provided to the chickens throughout the experiment. In the experiment following compositions of diet were used: a s tarter diet containing 23.23% CP and ME 3061 kcal/kg; a grower diet with 19.80% CP and ME 311 7 kcal/kg; and finisher diet with 19.0% CP and ME 3116 kcal/kg. The starter, grower and finisher diets used in the experiment are follows in an order: Group 1 on the days of 1-7, 8-35 and 36-42, Group 2 on the daysof1-14, 15-35 and 36-42, Group 3 on the days of 1-21, 22-35 and 36-42, Group 4 on the days of 1-7, 8-28 and 29-42, Group 5 on the days of 1-7, 8-14 and 15-42, Group 6 on the days of 1-7, 8-21 and 22-42. The starter and grower diets were given to the group 7 and 8 on the days of 1-14 and 15-42, 1-21 and 22- 42 respectively. In the first week, no significant differences were found in the liveweights of all the chickens fed with starter diets. Yet, in the following weeks, signifıcant differences were observed among the groups in regard to their liveweights {P < 0.05- P < 0.01 ). The highest live-weight was detected in the 2'ıd group from the week of the experiment. The feed conversion rates were found between 1.88-2.1 O on the 42-days-slaughtering age. The best feed conversion rate was found in Group 2. According to the results of this experiment, it was determined that while the broiler performance is significantly affected from the di et transition period from the starter diet to the grower diet, the di et transition from the grower to the finisher has not that much significance on the performance The days of 1-14, 15-35 and 36-42 were determined as the most suitable time for starter, grower and finisher feedings respectively.
