The aim of this study was to investigate the effects of live yeast culture and the live yeast culture enriched with vitamin-mineral supplementation as a feed additive on fattening performance, some blood and rumen fluid parameters in male kids. Totally 18 male Saanen goat kids (average 8 weeks old) were divided into one control and two treatment groups each containing 6 kids. Rations were prepared as isonitrojenic and isocaloric. Live yeast culture (LYC) and the yeast-vitamin-mineral complex (YVM) (RumiSacc® and Intetotal® respectively, Integra food Industry and Trade Co., Istanbul, Turkey, Live yeast cell 344 × 1010 cfu/g,) were incorporated into concentrates at the level of 0% (C), 1% (YC) and 1% (YVM) on as-fed basis. During the study concentrate feed and fresh water were given ad libitum and the ration did not contain any roughages. Dietary yeast culture at the level of 1 % increased final live weight (4.7% regarding control group) as numerically but not significantly. The fattening performance, rumen fluid and blood parameters were not statistically affected from the dietary treatments throughout the study. While the dorsal papillae length was not changed, ventral papillae length was decreased in the treatment groups. The length of papillae in YVM groups were similar to that of control groups.

This study was carried out to determine the effect of using chicken drippings oil (CDO) instead of the sunflower oil (SO) in laying Japanese quail diets on egg production, feed intake, feed conversion ratio, blood parameters, cholesterol level and fatty acid composition of egg yolk. A total of 192, thirteen week old Japanese quail were allocated to four groups with six replicates containing eight quail each. The diets contained 5% sunflower oil (SO1), 5% chicken drippings oil (CDO1), 7.5% sunflower oil (SO2), 7.5% chicken drippings oil (CDO2). The diets were formulated isonitrogenous and isocaloric, included 20% crude protein and 2900 kcal/kg ME. Experimental diets and water were provided ad libitum throughout the 9 weeks. There were no significant differences in initial body weight among the groups, but there were significant (P<0.001) differences in final body weight among the groups: 296.62, 286.62, 308.24, 276.35 g for SO1, CDO1, SO2 and CDO2 respectively. The egg production (P<0.001) of chicken drippings oil groups higher than the sunflower oil groups. The cholesterol levels in blood serum among groups were not statistically significant. At the end of the study cholesterol content of the egg yolk was the lowest in (P<0.05) the laying quail fed the CDO2 diet. All blood parameters including haemoglobin, heamotocrit, serum cholesterol and serum glucose were not affected by diets except serum triglyceride and serum protein P<0.01). Dietary chicken drippings oil had no adverse effect on egg weight, cholesterol and fatty acid composition of the egg yolk and feed conversion ratio. Therefore, chicken drippings oil can be use up to 7.5% of the laying quail diets. [ABSTRACT FROM AUTHOR]
