EFFECT OF BODY WEIGHT ON FEED INTAKE OF PULLETS AT THE ONSET OF LAY

Yıl 2011, Cilt: 15 Sayı: 3, 55 - 59, 21.02.2014

Öz

An experiment was conducted to investigate the effect of body weight on feed intake of pullets at the onset of lay. One hundred and thirty two Nick Brown Pullets were grouped into two according to their body weight, and caged singly. The range of body weight for the light and heavy groups was 1481 g to 1616 g, and 1617 g to 1752 g, respectively. Daily feed intake patterns of the two body weight groups were recorded in association to the onset of egg production, i.e. 5 days prior to, 5 days after and at initial oviposition. The differences in body weight were found to be related to daily feed intake of pullets at the onset of lay, moreover, daily feed intake increased with increasing body weight. These data indicate that average flock consumption is a poor indicator of consumption for birds of different body weight at the onset of lay.

Yapılan bu çalışmayla, yumurta başlanğıcındaki yarkalarda, canlı ağırlığın yem tüketimi üzerine etkisi incelenmiştir. 132 adet Nick Brown yarka canlı ağırlıklarına göre gruplandırıldı ve bireysel kafeslere yerleştirildi. Hafif ve ağır grup yarkalara ait canlı ağırlıklar sırasıyla hafif grupta 1481 g ile 1616 g, ağır grupta ise 1617 g ile 1752 g arasında değere sahiptir. Her iki canlı ağırlık grubunun günlük yem alım biçimleri yumurtlama başlangıcıyla ilişkilendirilerek kaydedildi, yani 5 gün öncesi, 5 gün sonrası ve ilk yumurtlama günü. Yumurtlama başlangıcındaki yarkaların günlük yem tüketimleri ile canlı ağırlık farklılıkları arasında ilişki bulunup, buna ek olarak canlı ağırlıktaki artış ile birlikte günlük yem tüketimi arttı. Bu veriler göstermektedir ki sürü ortalaması yem tüketimi, sürüdeki farklı canlı ağırlıktaki bireylerin yumurtlama başlangıcından zirve üretimine gerekli yem tüketimi için zayıf bir göstergedir
