Öğe Biological Suppression of Aflatoxicosis in Japanese Quail (Coturnix Coturnix Japonica) by Dietary Addition of Yeast (Saccharomyces Cerevisiae)(W B SAUNDERS CO LTD, 2001) Parlat, S. S.; Özcan, M.; Oğuz, H.The amelioration of aflatoxicosis in Japanese quails was examined by the dietary addition of live yeast (Saccharomyces cerevisiae; SCE). Yeast incorporated into the diet at 1 g kg(-1) was evaluated for its ability to reduce the deleterious effects of 2.5 mg total aflatoxin (AF; 82,30 per cent AFB(1), 2.06 per cent AFB(2), 7.68 per cent AFG(1) and 7.96 per cent AFG(2)) kg(-1) diet on growing Japanese quail chicks from 10 days to 45 days of age. Forty 10-day-old Japanese quail chicks were assigned to 2 x 2 factorial arrangement of treatment's (control, AF, SCE, AF plus SCE) each consisting of 10 quails. The performances of birds were evaluated. The AF treatment significantly and dramatically decreased food consumption and body-weight gain from the first week onwards. The significant adverse effect of AF on the food conversion ratio was also determined from week 1 to the end of the experiments. The addition of SCE to the AF-containing diet significantly reduced these deleterious effects of AF on food consumption, body-weight gain and food conversion ratio. Compared to controls, the cumulative body weight gain was reduced by 37 per cent among the quails consuming AF without SCE, but increased 15 per cent for the: birds fed AF plus SCE. Interestingly, the single inclusion of SCE to the AF-free diet provided significant improvements in all the investigated growth performances of birds (approximately 40 per cent) compared to controls.Öğe Growth performance and quality properties of meat from broiler chickens reared under different monochromatic light sources(TAYLOR & FRANCIS LTD, 2009) Karakaya, M.; Parlat, S. S.; Yilmaz, M. T.; Yildirim, I.; Ozalp, B.1. Quality properties of breast and drumstick muscles of female broiler chickens reared under different light sources were evaluated using a total of 480 female chicks (Ross 308). 2. After hatch, the chicks were randomly divided into three lighting treatment groups: control (daylight; mini incandescent lamps), G-B lighting group (green light monochromatic (MC) lamps for first 3 weeks switching to blue MC lamps for remaining 3 weeks), G-GB mixed lighting group (Green MC light for first 3 weeks, switching to Green MC light + Blue MC light mixture for remaining 3 weeks). 3. Feed consumption, body weight and total muscle weight values of the muscles from G-B and G-GB mix lighting groups were significantly higher than those of incandescent (control) lighting groups. 4. The breast and drumstick muscles from control lighting groups had a lower pH and water-holding capacity, but higher cooking loss values than those from G-B and G-GB mix lighting groups. The muscles from G-GB mix lighting groups exhibited the softer structure than those from other lighting groups. 5. We suggest that G-B or G-GB mix lighting during the rearing period of female broilers would improve body and muscle growth and then meat quality properties.Öğe Misuse of Multiple Comparison Tests in Some Animal Nutrition Experiments(INDIAN COUNC AGRICULTURAL RES, 1998) Parlat, S. S.; Yıldız, A. O.Object of some animal nutrition experiments related with graded levels of the orthogonal quantitative factor is to determine the mathematical relationship between orthogonal and non-orthogonal factors. Researchers are interested in effects of different levels of a quantitative factor on dependent variable and optimum levels of that factor. Quantitative factor levels are depended on each other and continuous. Multiple comparison test can be controlled only in determined levels. In the experiments where independent quantitative factor levels are main target, instead of concentrating on independent quantitative factor levels, making use of relationship between is more reasonable. Regression analysis should be applied instead of multiple comparison tests misused for such researches.Öğe A Novel Approach for Evaluation of Fattening Performance: Coefficient of Fattening Efficiency(EUGEN ULMER GMBH CO, 1996) Parlat, S. S.Basic scientific background for coefficient of fattening efficiency (CFE) proposed for the first time instead of traditional performance criteria which inadequately interprete the fattening trials was explained, and proper results were calculated by selecting a published paper in this subject. CFE described by Weight Gain/Feed Conversion Ratio could be formulated as Weight Gain (kg/d)(2)/Feed Intake (kg/d) and it would form a useful column heading in tables dealing with nutrition and growth.
