In this study, the effects of diet including different levels of olive cake were investigated on the fattening performance, blood parameters, certain slaughtering traits, and carcass quality of lambs. Thirty-six male lambs were used in the experiment. The lambs were randomly assigned to three groups with 12 lambs each. Groups included control, 12.5 and 25% olive cake (OC). The mixed feeds were offered ad libitum. All lambs were also allowed to consume alfalfa hay (83.8 g DM/animal/day). The experiment lasted for a period of 56 days. The effect of different levels of olive cake was not found different in fattening performance values of lambs in 0-56 days (P > 0.05). Carcass weight, pH, and yield were not different (P > 0.05). While the values of color parameters, cooking loss, tenderness, and ether extract level of longissimus dorsi muscle (MLD) was not found different (P > 0.05), it was determined that the levels of olive cake increased the water-holding capacity of meat (P < 0.05). Furthermore, although the levels of olive cake were shown to decrease total n-3 and total saturated fatty acids (Σ SFA), they also increased total n-6, n-6/n-3 ratio, total monounsaturated fatty acids (Σ MUFA), and total polyunsaturated fatty acids (Σ PUFA) were not different (P > 0.05).

ObjectiveThis study evaluated inclusion of buckwheat silage to the diet of growing lambs in terms of meat quality as compared to maize silage.MethodsBuckwheat, rich in total phenols (TP, 33 g/kg dry matter [DM]), was harvested at the end of the milk stage and ensiled in 40 kg plastic bags after wilting (294 g/kg silage DM). A total of 18 growing lambs (21.6±1.2) were individually fed isonitrogenous and isoenergetic total mixed rations (TMR) for 75 d that either contained buckwheat or maize silage at DM proportions of 0.50. At the end of feeding trail all lambs were slaughtered to assess carcass characteristics and meat quality.ResultsBuckwheat silage increased (p<0.01) the DM intake of lambs as compared to maize silage, but had no effects (p>0.05) on live weight gain and feed efficiency. Carcass weight, dressing percentage, meat pH, water holding capacity, cooking loss, shear force (kg/cm2), and total viable bacteria count of meat did not differ (p>0.05) between the treatments. However, TP content of meat increased (p<0.001) by feeding buckwheat TMR. Feeding buckwheat TMR also decreased (p<0.05) the b* values of meat.ConclusionThe results provide that buckwheat silage is palatable and could successfully include TMR of growing lambs with no adverse effects on performance, carcass and meat quality. Additionally, feeding buckwheat silage to lambs offers increased TP in meat.

Hayvanlar, mineral madde ihtiyaçlarının büyük bir çoğunluğunu tüketilen yemlerle karşılamakla beraber bir kısmını da içtikleri sudan alırlar. Fakat sudaki mineraller, rasyon hazırlanması sırasında genellikle göz ardı edilmektedir. Bu çalışmaya da konu olan su içeriğindeki mineral seviyelerinin aşırı yüksek olması, hayvanların tolerans kabiliyetlerine göre toksik ya da verim düşürücü etkileri olabilmektedir. Bu amaçla bu derlemede, Aydın ilindeki su kalitesini ortaya koyan değişik çalışmalar ve analiz sonuçları dikkate alınarak, hayvanların tolere edebildiği sudaki kimyasal parametrelerin yanında suya ait diğer bazı niteliksel parametrelerde irdelenmiştir. Anahtar Kelimeler: Aydın, çiftlik hayvanları, su kalitesi Assessment of Aydin Province Groundwaters in Terms of Drinking Water Quality for Livestock AbstractWater quality, although rich in groundwater and surface water resources in Aydın, even the output from different places according to the same local area are known to contain significant differences. Eventhough, animals meet most of their mineral requirements from feeds, a little part of them comes from water. But, minerals in water during preparation of the ration are usually ignored. The excessive high mineral content of the water that are also subject in this paper, it may be too toxic or yield-lowering effect according to the tolerance capability of the animals. For this purpose, in this paper, revealing the water quality in the province of Aydin considering various studies and analysis of results, chemical parameters in water that can be tolerated by the animals alongside some other qualitative parameters of water were examined.
