“…The pH, amonnia-N (NH3-N) and total volatile fatty acids (TVFA) contents of rumen liquid which are used to identify in vitro true digestibility of fodders, were found to be as 6.58 (5.91-6.85), 307 mg / l (264-402 mg / l) and 117 mmol / L (88-134 mmol / l), respectively. It was observed that the rumen liquid used in this study complies with the literature reports and that it offers standard rumen liquid properties (Kaya et al 2011;Sahin et al 2013).…”

This study was conducted to explore the effects of different forage types (fresh, hay and silage) on the chemical composition, forage quality and in vitro true digestibility (IVTD) of fodder turnip (Brassica rapa), fodder mustard (Brassica nigra) and canola (Brassica napus L.). Ankom Daisy incubator was used to determine the IVTD and forages were incubated for 48 hours. According to the findings of this study, canola silage and mustard silage have the highest ether extract (EE) content, while mustard silage has the highest crude protein (CP) content (P<0.001). It was found that, among the samples, turnip silage has the highest value in terms of neutral detergent fiber (NDF) content; mustard grass, turnip grass and canola hay have higher values in terms of lignin content while mustard silage has the lowest lignin content. As a result, it was concluded that grass, hay and silage obtained from Brassica fodder crops could be used as alternative forage souces. However, use of Brassica silages is recommended in ruminant nutrition.

“…However, final weight at the end of fattening and DLWG determined in the extensive group of this study were higher compared to values stated by Sarıçiçek et al [14] in Karayaka lambs for final weight (22.34 kg) and DLWG (78.14 g) in the pasture group. The reason for differences between studies was caused from differences in breed, Even though final weight at the end of fattening period stated in this study for semi-intensive group was lower than final weights (44.92 and 46.88 kg) of Tuj lambs in the groups which were given with 200 and 400 g concentrated feed along with pasture in the study conducted by Kaya et al [15] , DLWG was higher than DLWG values (160.57 and 183.14 kg) stated by the same researchers. DLWG in semiintensive group in this study was higher than DLWG values (98 and 118 g) in groups fed additionally in the study conducted by Saatcı et al [16] .…”

Citation of This ArticleÖnk K, Sarı M, Aksoy Y, Tilki M, Tufan T, Yılmaz İ: Effects of different fattening systems on fattening performance, slaughter and carcass characteristics of male Tuj lambs. Kafkas Univ Vet Fak Derg, 23, 109-115, 2017. DOI: 10.9775/kvfd.2016 AbstractThe purpose of this study were to determine effects of fattening systems on fattening performance (n=39) and slaughter and carcass characteristics (n=24) in male Tuj lambs. Three different fattening groups were formed as extensive (n=13), semi-intensive (n=13) and intensive (n=13). Lambs in the extensive group were grazed in pasture. In addition to pasture, concentrated feed was given to lambs in the semi-intensive group. High quality fodder and concentrated feed were given to those in the intensive group. The study was completed in 90 d. Final live weights of extensive, semi-intensive and intensive groups were 31.19, 41.22, and 40.56 kg (P<0.001), respectively, and for daily live weight gain were (DLWG) 117.52, 229.66, and 221.11 g (P<0.001), respectively. Feed conversion rates (FCR) were 3.05 and 5.16 respectively in the semi-intensive and intensive fattening. It was found that hot carcass weight was 13.41, 19.51, and 19.89 kg (P<0.001) in extensive, semi-intensive, and intensive fattening groups respectively. Hot carcass yield was 43.11, 46.95, and 49.77% (P<0.001) in extensive, semi-intensive, and intensive fattening groups respectively. Consequently; leg, foreleg, shoulder, neck, flank, and kidney percentages, and spleen and full stomach weights of lambs in the extensive group were higher than in semi-extensive and entensive groups. Although there was no statistical difference between semi-extensive and entensive groups in respect to fattening performance, slaugher weight, hot and cold carcass weights, entensive group was higher than the other groups in respect to hot and cold carcass yield.

“…the diets with 15 or 17% crude protein, suggesting that a protein level near 15% would be optimal for 25 to 40 kg growing lambs. In other studies, there was found no effect of protein level on DM intake, daily gain and feed efficiency (Kaya et al, 2009;Rocha et al 2004).…”

“…The need for protein depends largely on the breed, body weight and digestibility of protein in feed. In the finishing period, the need for crude protein (CP) level differs from 10-14.7% according to live weight and growing potential (Kaya et al, 2009). In other studies, it is suggested that the optimum CP level required in fattening lamb's diets is usually in the range of 14 to 16% (Milton and Paterson, 2001).…”

Background: A correct supply of protein in the feed diets is required for the efficient conversion of feed and better fattening performances in lambs. This study aimed to investigate the effects of the increase in the protein level of the diets by approx. 20% on fattening performance and meat parameters in Merino lambs. Methods: The study was performed during the year 2020. Forty-two lambs (aged 2.5-3 months) were divided randomly into three groups (14 lambs/group). The groups were fed with diets of compound feed and corn silage differentiated by the level of protein. All diets were isoenergetic. The experiment has lasted for 68 days. Result: The results of this study showed that the protein supplementation of diets by approx. 20% determined an increase in the average daily gain (P less than 0.05) in the first phase of fattening and an improvement in dry matter and protein consumption when the protein supplementation was done only in the first phase of fattening in Merino lambs. Also, the findings of this study indicated that this increase in protein level affected carcass quality and led to higher proportion of muscles and significantly lower fat in the carcass.
