Abstract

This research was carried out to determine the effects of concentrated feed mixtures with different energy levels (600, 650 and 700 Starch Equivalent) on fattening performance, some slaughter and carcass characteristics of Holstein bulls fattened at open barns of Central Research Institute for Field Crops, Ankara, in winter. The concentrated feed mixtures were given to animal groups ad-libitum and straw was limited to 1 kg/ head/ day. The initial and final live weights, total weight gains and average daily live weight gains and feed efficiency values of groups, during the fattening period were found as: 240.1, 455.6. 215.5. 1.184 and 7.88 kg for group I; 240.0, 465.7, 225.8, 1.240 and 7.48 kg for group II; 242.6, 463.4, 220.8, 1.213 and 7.76 kg for group HI, respectively. The slaughter-house weights, dressing percentages (from cold carcass weight), abdominal and kidney-pelvic-cavity fat weights were determined as: 446.7 kg, -55.28 %, 2.94 kg and 3.35 kg; 452.3 kg, 56.08 %, 3.27 kg and 3.90 kg; 452.3 kg, 56.56 %, 3.09 kg and 4.03 kg, respectively.

Özet

Bu araştırma, farklı enerji düzeyli kesif yemlerin (600, 650 ve 700 NB) kış mevsiminde açık barınaklarda besiye alınan Siyah Alaca erkek danaların besi gücü, bazı kesim ve karkas özelliklerine etkilerini saptamak amacıyla Tarla Bitkileri Merkez Araştırma Enstitüsünde düzenlenmiştir. Bütün danalar besi boyunca sınırlı olarak 1 kg saman ile ad-libitum düzeyde kesif yem tüketmişlerdir. Grupların besi başı ve besi sonu canlı ağırlıkları, besi boyunca sağladıkları toplam ve günlük ortalama canlı ağırlık artışları ve 1 kg canlı ağırlık artışı için kesif yem tüketimleri sırasıyla; 1. grupta 240.1, 455.6, 215.5, 1.184 ve 7.88 kg; 2. grupta 240.0, 465.7, 225.8, 1.240 ve 7.48 kg; 3. grupta 242.6, 463.4, 220.8, 1.213 ve 7.76 kg bulunmuştur. Kesimhane ağırlığı, soğuk karkas randımanı, iç yağ ve böbrek-leğen yağlan ağırlığı sırasıyla; 1 grupta 446.7 kg, % 55.28, 2.94 kg ve 3.35 kg; 2. grupta 452.3 kg, % 56.08, 3.27 kg ve 3.90 kg; 3.grupta 452.3 kg, % 56.56, 3.09 kg ve 4.02 kg olarak saptanmıştır.
