Comparison of Growth Models of Male and Female Partridges
(Asian Network for Scientific Information, 2007) Cetin, M.; Sengul, T.; Sogut, B.; Yurtseven, S.
This study was conducted to compare the growth curves of male and female partridges (Alectoris chukar) using Gompertz, Richards and Logistic models. Parameters were estimated using biomathematical analysis. Weight (y+) and age (t+) at inflection, the ratio inflection/asymptotic weight (y+/A) and the degree of maturity weekly (ut = yt/A) were estimated by taking advantage of the parameter. Standard error of estimate and coefficient of determination (R2) were used to choose model criterion. Durbin-Watson test was used for auto-correlation in the error terms. Calculated weight (y+) and age (t+) at inflection Point (POI) and the ratio inflection/asymptotic weight (y+/A) for both males and females in Gompertz model were smaller than the other models. Calculated y+/A (0.368) for both sex was similar in Gompertz model. According to results of this study, Gompertz model had better explanation for growth phenomena of males and females partridges than the other models. The 70 and 90% of the maturity degree was completed at approximately 10-12 and 16-18 weeks, respectively. These results give some ideas about growth period of commercial breeding of partridges. © 2007 Asian Network for Scientific Information.
Effect of Sage Extract (Salvia Officinalis) on Growth Performance, Blood Parameters, Oxidative Stress and Dna Damage in Partridges
(South African Journal of Animal Sciences, 2008) Yurtseven, S.; Cetin, M.; Sengul, T.; Sogut, B.
This study was performed to evaluate the effect of different doses of sage extract on the growth and blood parameters, oxidative stress and DNA damage in partridges. In total, 252 day-old partridges (Alectoris chukar) were used. The birds were divided into four groups: 0.1% flavomycin was included in the diet of the control group (1) while 2.5, 5.0 and 7.5 mL sage extract/kg were Included in the diets of treatment groups 11, III and TV, respectively. At the end of the experiment no significant differences between treatments were observed in live weight, live weight gain, feed consumption, feed conversion ratio, carcass weight and Survival rate. In addition, blood analyses indicated that the differences between groups in the amounts of plasma cholesterol, triglyceride high density lipoprotein (HDL), very low density lipoprotein (VLDL) and alkaline phosphates (ALP) were not significantly different. Furthermore, treatments did not affect total sulphydryl (SH) and lipid hydroperoxide (LOOH) concentrations, total antioxidant response or the total oxidant status (TOS). However, sage extract significantly decreased DNA damage in a linear, dose-dependent manner whilst the antibiotic, flavomycin, elevated the oxidative stress index (OSI) and resulted in DNA damage. It was concluded that supplementing sage extract in the partridge diet at the doses studied does not lead to a negative effect oil the growth performance of these birds.
Effect of Thyme (t-Vulgaris) Extracts on Fattening Performance, Some Blood Parameters, Oxidative Stress and Dna Damage in Japanese Quails
(Kielanowski inst Animal Physiology Nutrition, 2008) Sengul, T.; Yurtseven, S.; Cetin, M.; Kocyigit, A.; Sogut, B.
The study was conducted to determine the effects of supplemented thyme oil extract and thyme water extract, the water soluble fraction of thyme extract, on fattening performance, blood parameters, oxidative stress and DNA damage in Japanese quails. Two hundred sixteen chicks were divided into four groups: control (no antibiotic or thyme extracts (I), flavomycin (II), thyme oil extract (III) and thyme water extract (IV). Groups II and III received 1 g/kg flavomycin as an antibiotic and 2.5 ml/kg thyme oil extract, respectively. Birds in group IV received 100 ml/l of thyme water extract in their drinking water. There were no significant differences in liveweight between the treatment groups, but feed intake differed (P<0.01) at 0-5 weeks of age. Results showed that thyme extracts decreased feed consumption during the experiment. Similarly, the survival rate differed significantly (P<0.01) between groups; the lowest was in antibiotic group. The levels of plasma cholesterol, triglyceride, high density lipoprotein, very low density lipoprotein and alkaline phosphates were similar in the four treatments. The highest rate of total oxidant status and total antioxidant response were found in group III, the lowest rate of DNA damage in the thyme oil (III) and thyme water extracts (IV) groups. It was concluded that supplementing thyme extract products in the diet of quails at the doses studied does not lead to a negative effect on the growth performance of the birds. Supplemented antibiotic caused an elevation in the oxidative stress index and in DNA damage.
