The Effects Of Season And Chick Sex On Certain Performance Parameters In Commercialturkey Farms In The Aegean Region, Gündüz İlsever, Pembe Di̇lara Keçi̇ci̇, Bülent Eki̇z
Turkish Journal of Veterinary & Animal Sciences
The aim of this study was to determine the effects of season and sex on the production efficiency of commercial turkey farms in the Aegean Region. The data of 1161 production periods (570 male and 591 female) on 139 turkey farms between 2008 and 2017 were analysed. Daily feed consumption, feed conservation ratio (FCR), average daily gain (ADG), performance index, and carcass weight (P < 0.001) were higher in males than females. While males and females had a similar mortality rate in the first week (P > 0.05), the mortality rate in the later stages was higher in males (P < 0.001). The mortality rate in the initial period was highest in production periods that began in winter and lowest in those that began in summer (P < 0.001). The total mortality rate was higher in the autumn group than in the spring and summer groups (P < 0.001). Rearing season × sex interaction had a significant influence on the performance characteristics investigated in the study, except for mortality rates and survival. In males, FCR was lower in the autumn and winter groups than that of the spring and summer groups (P < 0.05). The highest ADG values were observed in the summer group for males and in the winter group for females. The best performance index was in the summer group in males, and the lowest performance index was observed in the autumn group for both males and females. In conclusion, environmental arrangements are needed in order to reduce the mortality rate and improve performance in production periods that began in autumn and winter.

Turkish Journal of Veterinary & Animal Sciences
The objective of this study was to compare the effects of two concentrate allotment strategies on the performance of dairy cows grazing on restricted pasture and supplemented with conserved forage. Dairy cows fed equal amounts of concentrate (fixed daily rate: 5.5 kg DM/cow) were compared to cows supplemented with concentrate according to their lactation stage as follows: 10.0, 5.0, and 1.5 kg DM/cow daily during early, mid, and late lactation, respectively (average daily dose: 5.5 kg DM/cow). There was a supplementation strategy × lactation stage interaction (P < 0.05) for energy-corrected milk (ECM). For early lactation cows, supplementation at a variable rate increased ECM yield by 14.61% (P < 0.05). There was a supplementation strategy × lactation stage interaction (P < 0.05) for body weight change. At late lactation stage, cows supplemented at a fixed rate gained weight (+ 0.16 kg/day), whereas those supplemented at a variable rate lost weight (- 0.08 kg/day; P < 0.05). No significant effect was found for body condition score. The prioritization of milk production rather than the attenuation of body reserve mobilization suggests that concentrate allowance based on lactation stage may be unsuitable for minimizing the negative energy balance in early lactation cows.

Turkish Journal of Veterinary & Animal Sciences
he current study aims to compare sugar beet leaves (SBLs) ensiled with sugar beet pulp (SBP), sugarcane molasses (SM), or rock candy juice (RCJ) using an in vitro gas production technique. Treatments in the first group included 10% SBP (control 1) and control 1 plus 5% SM or RCJ. In the second group, there were 3 treatments, including 20% SBP (control 2) and control 2 plus 10% SM or RCJ. The silages with no added soluble carbohydrate (SC) sources had significantly higher (P < 0.001) pH, buffer value index, and ammonia nitrogen values than the other treatments. However, there was no significant difference between RCJ and SM in their effect on these variables. Adding both levels of SC sources caused an increase in dry matter digestibility compared to those that only included SBL and SBP (P < 0.001). Maximal and rate of gas production from slowly fermentable fraction (a$_{2}$) were significantly greater when the substrate contained 85%, 10%, and 5% SBL, SBP, and SC sources, respectively. Using dried SBP and SC sources for the preservation of fresh SBL is recommended; however, with higher levels of SC, the silage may be at risk of spoilage, and it must be less exposed to air.

Birds from the experimental groups were orally infected with 500 (GI) or 1000 (GII) sporulated oocysts of E. tenella and then examined for weight gain, biochemical indicators, and microbiota on day 9 and 16 after infection. Experimental infection of E. tenella on day 9 post infection (pi) increased concentrations of uric acid, cholesterol, triacylglycerols, and glucose; however, these measurements did not differ from those of the control group on day 16 pi. On day 16 pi, bifidobacteria counts were …

In this study, findings of morphological deformation observed on a blue crab sampled in Köyceğiz Lagoon (Muğla, Turkey) are presented. The deformation is in the left lateral spine. It has been observed that this spine, which normally should have been one, developed as two independent spines. Due to this abnormality observed in the individual, the individual has two carapace widths.
