Determination of The Feedlot Performance and Ration Cost in Charolais Breed Heifers Before Insemination

Öz

The objective of the current study was to determine the feedlot performance and ration cost in Charolais breed heifers before insemination. In this research, 65 Charolais head heifers at 9-10 months of age were used. Rations were prepared according to the protein and energy needs of heifers. Feedlot performance and daily feed costs of heifers were determined at the end of each feeding period. In the study, monthly daily gain (kg) of heifers were determined as 41,29±10,82, 34,00±6,85, 37,38±9,80, 25,14±9,58, 27,82±11,24 daily gain (kg) as 1,38±0,36, 1,13±0,23, 1,25±0,32, 0,84±0,31, 0,93±0,37 (P<0,05), respectively. The highest cost of feeding per animal was in the 3rd period (7,25±1,90TL) and the lowest cost was in the 1st period (6,10±1,60TL). Due to the high feed costs in dairy cattle breeding, it is important to control feed costs by carrying out such studies with different rations.

Şarole Irkı Düvelerde Tohumlama Öncesi Beslenme Performansını ve Rasyon Maliyetlerinin Belirlenmesi

Öz

Bu çalışmanın amacı şarole ırkı düvelerde tohumlama öncesi beslenme performansı ve rasyon maliyetlerinin belirlenmesidir. Araştırmada 9-10 aylık yaşta 65 baş şarole ırkı düve kullanılmıştır. Rasyonlar, düvelerin protein ve enerji ihtiyaçları göz önüne alınarak hazırlanmıştır. Her besleme dönemi sonunda düvelerin beslenme performansları ve günlük yem maliyetleri belirlenmiştir. Araştırmada düvelerin aylık canlı ağırlık (kg) artışları dönemlere göre sırasıyla; 41,29±10,82, 34,00±6,85, 37,38±9,80, 25,14±9,58, 27,82±11,24 günlük canlı ağırlık artışları (kg) ise; 1,38±0,36, 1,13±0,23, 1,25±0,32, 0,84±0,31, 0,93±0,37 olarak tespit edilmiştir (P<0,05). Hayvan başına en yüksek rasyon maliyeti 3. dönemde ( 7,25±1,90TL), en düşük rasyon maliyeti ise 1. dönemde (6,10±1,60TL) gerçekleşmiştir. Süt sığırı yetiştiriciliğinde yem giderlerinin yüksek olmasından dolayı farklı rasyonlarla bu tip çalışmaların yapılarak yem maliyetlerinin kontrol altına alınması önem arz etmektedir.
