    Effects of dietary supplementation with distiller dried grain with solubles in growing lambs on growth, nutrient digestibility and rumen parameters
    (Ecole Nationale Veterinaire Toulouse, 2013) Sahin, T.; Kaya, O.; Elmali, D. Aksu; Kaya, I.
    This study aims to evaluate the effects of distiller dried grains with solubles (DDGS) incorporated to the concentrate ration in growing lambs on weight growth, food consumption and efficiency, nutrient digestibility and some rumen parameters. After a 15 days long adaptation period, the 2.53 month old male Tuj lambs were divided into 3 equal groups of 6 lambs each according to the proportions of DDGS (0, 10 and 20%) added to the concentrate in substitution of soybean meal. Food intake, weights and weight gains, food efficiency were recorded for 50 days then in the last week of the experimental period, nutrient digestibility rates were determined by collecting total faeces, and pH, concentrations of ammonia and volatile fatty acid were measured in ruminal fluid. Dietary DDGS addition has exhibited negative effects neither on growth performance, food intake of forage or concentrate and food efficiency nor on rumen parameters. However, the digestibility rates of dry and organic matters and of crude proteins were significantly depressed when 10% DDGS were used. These results show that DDGS at 20% can be used as a protein source in the growing lamb diet.

    Effects of plant extracts and (essential) oil mixture on breast meat quality of Japanese quails (Coturnix coturnix japonica)
    (Ecole Nationale Veterinaire Toulouse, 2014) Elmali, D. Aksu; Yakan, A.; Kaya, O.; Elmali, M.; Onk, K.; Sahin, T.; Durna, O.
    The objective of this study is to determine the effects of vegetable extracts and oil mixture, which is based on adding peppermint, thyme and anise to drinking waters, on the quality of breast meat in quails. Three groups of 14 quails (one-day old) with 7 males and 7 females were defined. The quails were fed ad libitum during 35 days with a 22% of crude protein and 12.9 Mj/kg of metabolizable energy diet. Two groups received fresh drinking water supplemented with 1 ml/5 l and 1.5 ml/5 l of plant extracts and oil mixture, respectively. The control group received non-supplemented drinking water. Several quality characteristics including pH, water-holding capacity, cooking loss, color, malondialdehyde, dry matter, crude ash, ether extract, crude protein, and fatty acids were defined in the breast meats of the quails slaughtered after the trial. No differences among the groups or sexes were defined for pH, water-holding capacity, cooking loss, color, dry matter, crude ash, ether extract, crude protein, and total and index values of fatty acids in the breast meat. At 24 hour the groups that were supplemented in oil mixture had a meat malondialdehyde level lower (P<0.05) than the control group. As a result, adding vegetable extracts and oil mixture to the drinking waters did not affect the breast meat qualities but increased significantly the antioxidant characteristics of the meat. Accordingly, it was concluded that addition of 1ml/5 l and 1.5 ml/5 l vegetable extract and oil mixture to the drinking waters of quails improve the quality of meat.
