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.
The Effect of Lentil-By Product on Growth Performance and Carcass Traits of Heavy White Turkeys
(Facta-fundacio Arnco Ciencia Tecnologia Avicolas, 2018) Sogut, B.; Kurbal, O. F.; Inci, H.; Ayasan, T.
The subject of this study was to figure out the effects of lentil by product (LP) on growth performance and carcass traits of the white heavy turkeys. To accomplish this goal, a total of 210 day old big-6 turkey chicks were used. The birds were divided into 7 seven groups with 3 replicates. The 1st, 2nd, 3rd, 4th, 5th, 6th and 7th groups received 0, 5, 10, 15, 20, 25 and 30 % lentil by product, respectively. All the diets were made as izonitrojenic and izocaloric. The highest live body weights of males and females were observed in the control group at the end of the 15th week, which was the time of slaughtering of females, however the differences between the control and the 2nd, 3rd and 4th groups were not significant (p>0.05). The same differences continued for males at the end of the 17th wk of age, which was the time of slaughtering of males. Similar results were observed in carcass traits, as well. The best FCR was noted in the control group and it was significantly (p<0.05) different than in the treatment groups. The lowest and highest feed intake was observed in the 7th and 3rd groups. No significant differences were observed between control and all treatment groups. As a result, it could be said that lentil by product could be added into turkey diets up to 15% with no negative effect on live body weight and carcass traits because there was no significant differences between control and treatment groups (5, 10,15 % LP).
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.
The Effects of Feed Restriction and Ambient Temperature on Growth and Ascites Mortality of Broilers Reared at High Altitude
(Oxford Univ Press, 2010) Ozkan, S.; Takma, C.; Yahav, S.; Sogut, B.; Turkmut, L.; Erturun, H.; Cahaner, A.
The development of ascites was investigated in broilers at low versus high altitudes, cold versus normal ambient temperatures (AT), and 3 feeding regimens. One-day-old chicks obtained at sea level were reared at high altitude (highA; 1,720 m; n = 576) with 2 AT treatments, low AT from 3 wk onward at highA (highA/cold) and normal AT from 3 wk onward at highA (highA/norm), or at sea level (normal AT from 3 wk onward at low altitude, lowA/norm; n = 540). Under highA/cold, AT ranged between 16 to 17 degrees C in the fourth week, 17 to 19 degrees C in the fifth week, and 19 to 21 degrees C thereafter. Under highA/norm and lowA/norm, AT was 24 degrees C in the fourth week and ranged between 22 to 24 degrees C thereafter. Broilers in each condition were divided into 3 groups: feed restriction (FR) from 7 to 14 d, FR from 7 to 21 d, and ad libitum (AL). Ascites mortality and related parameters were recorded. Low mortality (0.4%) occurred under lowA/norm conditions. Under highA/norm, mortality was lower in females (8.6%) than in males (13.8%) and was not affected by the feeding regimen. The highA/cold treatmentresulted in higher mortality but only in males; it was 44.2% among highA/cold AL-fed males and only about 26% under the FR regimens, suggesting that FR helped some males to better acclimatize to the highA/cold environment and avoid ascites. However, mortality was only 13.3% in AL-fed males at highA/norm and FR did not further reduce the incidence of ascites under these conditions. Thus, avoiding low AT in the poultry house by slight heating was more effective than FR in reducing ascites mortality at highA. Compared with FR from 7 to 14 d, FR from 7 to 21 d did not further reduce mortality and reduced growth. At 47 d, the majority of surviving broilers at highA had high levels of hematocrit and right ventricle: total ventricle weight ratio (>0.29), but they were healthy and reached approximately the same BW as their counterparts at low altitude. This finding may suggest that in broilers reared at highA from day of hatch, the elevation in hematocrit and in right ventricle: total ventricle weight ratio happens gradually and therefore is not necessarily indicative of ascites development.
Growth Performance of Big-6 Broiler White Turkeys in the Different Rearing Conditions
(2010) Sogut, B.; Kurbal, O.F.; Demirulus, H.; Inci, H.
This study was conducted to determine the effect of rearing partially outdoor and indoor conditions on growth rate and carcass yields of Big-6 heavy white turkeys. Totally 144 white toms were divided into 3 groups (Pasture-1, Pasture-2 and Control) with 6 replicates, randomly. Pature-1 (PI) and Pasture-2 (P2) had outdoor access from 42 and 49 days old till end of the trail, respectively, while control group was kept indoor. All birds consumed commercial turkey breeding feed. At the end of trial, no significant differences were observed in terms of body weight but the best one was the control group. The lower feed consume and the best feed to gain was observed in PI (3.06) and P2 (3.56) then Control group (3.73), which was significantly different (p<0.05). Outdoor access did not have significant effect on carcass weight, breast meat and legs (Thights + drumstick) but it differed the wings (p<0.05). As a result, it has been said that Big-6 heavy Turkeys have to be fed inside without outdoor access so far. According to results of present study, one may say that Big-6 white turkey could be grazed with no deleterious effect on growth performance. However, more study is needed to determine age of access to outdoor and growth performance of Big-6 white turkeys at different grazing fields. © Medwell Journals, 2010.
