“…Those differences could be due to the fact that lambs in RFC had lower contact with pathogens (parasites and bacteria mainly) (Hernández-Cortazar et al 2014), had efficient use of food because the lambs reduced their energy expenditure in activities (Lupton et al 2007) and a better ventilation allowing a good animal performance. Rihawi et al (2010) found that adding artificial ventilatión for lambs during fattening in the outdoor condition showed better daily gain weight compared to confinement without ventilation. The confinement in sheep production for temperate regions has showed stress episodes caused by warm environmental conditions during summer in ewes (Centoducati et al 2015) or during the finishing phase of fattening, decreasing the performance of feedlot lambs.…”

“…Intensive lamb fattening systems have received considerable attention in many parts of the world, due to the high demand for lambs at favourable prices (Hartwell et al 2010;Rihawi et al 2010). In the Mexican tropics, there is an increase in intensive feedlot systems to improve sheep production efficiency (Muñoz-Osorio et al 2016).…”

“…However, in the warm season, confinement is not appropriate to fattening lambs unless it is air conditioned which increase the production cost. In the dry regions of Syria, during summer (environment temperature 35-40°C), lamb fattening outdoor (open barn under a shed) showed better performance than indoor (Rihawi et al 2010). Under the warm condition, the confinement without good ventilation induces heat stress in animals and deleterious effect on welfare and performance (Rihawi et al 2010;Centoducati et al 2015).…”

In the sub-humid tropics of Mexico, intensive lamb fattening systems in raised slatted floor cages (RFC) have been promoted to prevent the contact between animals and faeces and to provide adequate ventilation for them.…”

The effect of two housing systems during the fattening period on productive performance of lambs from different hair-type sheep breeds in southeastern Mexico was evaluated. Effects of housing system (raisedslatted floor cages (RFC) vs. floor pens (FP)), year (2009, 2012 and 2013) and season of the year (rainy vs. dry) on average daily gain (ADG), weights adjusted to 60 (P60) and 90 (P90) days post-weaning were evaluated. Data from 1213 lambs collected on the farm over a period of three years were analysed. The ADG, P60 and P90 were affected (P < .01) by the housing system, year and the housing system × year interaction. The season was not a significant source of variation. Lambs housed in RFC were heavier (ADG 306.5 ± 2.69 g, P60 33.2 ± 0.16 kg, P90 42.4 ± 0.24 kg) than those in FP (ADG 269.4 ± 4.24 g, P60 30.9 ± 0.25 kg, P90 39.0 ± 0.38 kg) (P < .01); however, the significant interaction housing system × year suggests that productive performance of lambs may vary between years, despite the housing system. It was concluded that productive performance of hair lamb was affected by housing systems, year and their interaction.ARTICLE HISTORY

“…In the study conducted by Rihawi et al (15) in Syria, the total cost excluding fattening materials throughout the 49-day fattening process for Awassi lambs varied according to test groups, and was calculated between US$ 8.97-11.27 (At time of printing, ₺ 1 = US$ 0.56). On the other hand, in the studies of Hartwell et al (11), the total cost excluding fattening material in Awassi lambs subject to fattening for a period of 90 days with the extensive fattening system and with three different rations was reported to be between US$ 22.2-25.0, and the cost for 1 kg LWG was reported to be US$ 0.89-0.98.…”

Summary:This study aims to determine the most profitable fattening system through an economic analysis of lamb fattening in different fattening systems under controlled conditions which was performed for the first time in Turkey. The material of the study consists of 39 weaned lambs of 2.5-3 months old from each of the Tuj and Hemşin genotypes. In the study, the lambs were separated into the 3 fattening groups of extensive, semi-intensive and intensive including 13 Tuj and 13 Hemşin lambs in each group through the systematic sampling method in a diagonal manner and these lambs were subject to 90 days-fattening. As a result of the economic analysis, the daily cost per animal, and output/input ratio for Tuj lambs in the extensive, semi-intensive, and intensive fattening systems were respectively determined to be ₺ 0.94 TL-1.05, ₺ 1.69 TL-1.20, and ₺ 1.99 TL-1.12 and the same values were respectively determined to be ₺ 0.95 TL-1.04, ₺ 1.70 TL-1.11, and ₺ 2.00 TL-1.09 for Hemşin lambs. All the fattening systems are statistically different from each other in the fattening of Tuj and Hemşin lambs in terms of total costs (P<0.001). On the other hand, a statistically significant difference was determined between the extensive fattening system and other fattening systems in terms of net profit and output/input ratios (P<0.001). In conclusion, as the total costs, 1 kg carcass, 1 kg live weight gain, and 1 kg live weight costs are lower; on the other hand, as net profit and input/output ratios in the semi-intensive fattening system are higher compared to the intensive fattening system, for Tuj and Hemşin lambs the semi-intensive fattening system is recommended.Keywords: Cost/benefit, Hemşin, lamb fattening, profitability, Tuj. Kontrollü koşullarda Tuj ve Hemşin kuzularıyla yapılan farklı besi sistemlerinin fayda/maliyet analiziÖzet: Bu araştırma ile Türkiye'de ilk defa kontrollü koşullar altında farklı besi sistemlerinde kuzu beslemenin ekonomik analizi yapılarak, en karlı olan besi sisteminin belirlenmesi amaçlanmıştır. Araştırma materyalini Tuj ve Hemşin genotiplerinden 2.5-3 aylık yaşta sütten kesilmiş, 39'ar baş erkek kuzu oluşturmuştur. Çalışmada kuzular sistematik örnekleme metoduyla çapraz olarak her grupta 13 baş Tuj ve 13 baş Hemşin olacak şekilde ekstansif, yarı entansif ve entansif olmak üzere 3 farklı besi grubuna ayrılmış ve 90 günlük besiye tabi tutulmuştur. Ekonomik analiz sonucunda Tuj kuzularında ekstansif, yarı-entasif ve entansif besi sistemlerine göre hayvan başına günlük maliyet ve output/input oranı sırasıyla ₺ 0.94 TL-1.05, ₺ 1.69 TL-1.20 ve ₺ 1.99 TL-1.12 iken, aynı değerler Hemşin kuzularında ise sırasıyla ₺ 0.95 TL-1.04, ₺ 1.70 TL-1.11 ve ₺ 2.00 TL-1.09 olarak tespit edilmiştir. Tuj ve Hemşin kuzularının besisinde toplam masraflar yönünden bütün besi sistemleri birbirinden istatistik olarak farklıdır (P<0.001). Diğer taraftan net kar ile output/input oranı açısından ise ekstansif besi sistemi ve diğer besi sistemleri arasında istatistik olarak anlamlı bir fark tespit edilmiştir (P<0.001). Sonuç ol...
