This research was carried out to determine milk yield and milk quality parameters of Awassi sheep raised under semi-intensive conditions in Harran University Experimental Animal Research and Application Center. In the study, 2 and 3 years old, 46 heads of Awassi sheep were used as animal material. The care and feeding of the ewes were made in a way that the Animal Research and Application Center routinely applied. Average daily milk yield in Awassi sheep was determined as 1002.82±52.57 g. Lactation milk yield and lactation period were calculated as 168.10±8.44 kg and 166.10±2.11 days, respectively. In the study, the overall mean fat, protein, lactose and dry matter ratios were determined. % 6.27±0.10; 5.12±0.05; 4.81±0.05 and 17.44 ± 0.13 respectively. Somatic cell count and pH values in Awassi sheep milk were determined as 207.56±21.29 cell/ml and 6.29±0.03 respectively. L*, a* and b* values in sheep milk were determined as 72.69±0.16; -6.11±0.04 and 6.92±0.08. respectively. It was determined that the amount of butyric acid (C4:0), which is one of the short-chain fatty acids, was higher than the values reported for sheep milk in all groups examined in the study. As a result, it has been determined that there is a wide variation in milk yield in Awassi sheep. A rapid genetic improvement may be achieved by utilizing this variation.

Tr en Bu çalışma, bıldırcın rasyonlarına eklenen nane yağının büyüme performansı, et kalite, renk ve kan oksidatif stres özellikleri üzerine etkisini araştırmak amacıyla yürütülmüştür. Bu amaçla 10 günlük yaşta 40 adet japon bıldırcını kullanılmış ve deneme 35 gün sürdürülmüştür. Araştırma grupları, her birinde bireysel olarak 10 bıldırcın bulunan 4 gruba ayrılmıştır. Bıldırcınlar için hazırlanan rasyonlarda, kontrol grubunda herhangi bir yem katkı maddesi kullanılmazken, diğer grupların yemlerine %0.1, %0.2 ve %0.3 Nane Yağı (NY) ilave edilmiştir. Deneme genelinde Canlı ağırlık (CA), Günlük canlı ağırlık artışı (GCAA), Günlük yem tüketimi (GYT), Yemden yararlanma oranı (YYO), karkas ve kesim özellikleri ile renk ve pH bakımından gruplar arasında fark gözlenmemiştir. Ancak kanda toplam oksidatif durum (TOS)’u önemli ölçüde düşürdüğü ve toplam antioksidan durum (TAS)’u ise yükselttiği tespit edilmiştir. Sonuç olarak bıldırcın rasyonlarına nane yağı ilavesinin besi performansı ve karkas özelliklerini değiştirmediği ancak TAS değerlerini yükselttiği ve TOS değerlerini düşürdüğü için yem katkı maddesi olarak rasyona %0.1 oranında NY eklenmesinin faydalı olacağı görülmüştür. This study was conducted to investigate the effects of peppermint oil added to quail diets on growth performance, meat quality characteristics, meat color and blood oxidative stress characteristics. For this purpose, 40 Japanese quails were used at the age of 10 days and the experiment was continued for 35 days. The study groups were divided into 4 groups, each containing 10 quails. The control group was fed with a diet without any additives while 0.1%, 0.2% and 0.3% peppermint oil (PO) were added to the feed of the other groups. There was no significant difference between groups in terms of body weight (BW), daily body weight gain (DBWG), daily feed consumption (DFC), feed conversion ratio (FCR), carcass and slaughter characteristics, color and pH values. However, it was found that addition of 0.1% PO significantly reduced total oxidative status (TOS) and increased total antioxidant status (TAS) in blood. The results indicated that adding peppermint oil to quail rations at rate of 0.1% PO would be useful as an additive improving TAS and reducing TOS values although PO addition did not change feeding performance and carcass characteristics of quails.

This study was carried out to determine the effect of different industrial by-products (pistachio, pomegranate, and olive) as alternative feed sources for sheep. Fifty-two Awassi sheep aged 3 and 4 years were divided into four groups (n=13 per group) concerning age, birth type, milk yield, and lactation period: basal diet without byproducts (CON) and basal diet added with either pistachio shell (PIS), pomegranate hull (POM), or olive pulp (OP). By-products were mixed with the total ration at a rate of 5% and given in the morning and evening feedings. The feeding experiment was continued for 60 days. Milk yield, milk quality, feed consumption, and biochemical parameters such as urea, creatine, triglyceride, total bilirubin, and albumin were determined at 30-day intervals from the beginning of the study. Tukey multiple comparison test was used to compare the research groups. There was no treatment effect on feed consumption. The highest milk yield was measured in sheep fed the POM diet in all periods (the first, second, and third-period means were 1143±111, 967±127, and 785±112 gr, respectively). Milk yield for other groups was similar. At the end of the study, the fat ratio in the CON, PIS, POM, and OP groups were determined to be 6.11±0.30%, 6.25±0.36%, 5.61±0.42%, and 5.97±0.48%, respectively. Protein values were determined as 6.34±0.16%, 6.26%±0.27%, 6.06%±0.23%, and 6.39±0.19% in the same order. There was no statistically significant difference between CON, PIS, POM, and OP groups regarding biochemical parameters. In conclusion, sheep ration can contain PIS, POM, and OP up to 5% as alternative feed sources.

Objective. This study was conducted to research the effects of different levels of dried white mulberry (Morus alba) pulp supplementation in diets of laying quail on yield performances, egg quality, blood parameters, yolk fatty acid profiles and cholesterol concentrations. Materials and Methods. A completely randomized experimental design, with four treatments and four replicates, was applied. The experimental treatments were M0: control diet; M4: dietary inclusion of 4% mulberry pulp; M8: dietary inclusion of 8% mulberry pulp; M12: dietary inclusion of 12% mulberry pulp. This experiment was carried out for 4 weeks, and 128 7-week-old female quail were used. Results. Addition of dried mulberry pulp to the diet significantly affected weekly feed intake, egg yield, albumin index, yolk weight, triglyceride, LDL, serum cholesterol and yolk cholesterol levels (p<0.05, p<0.01). The feed conversion ratio, egg weight, and egg yolk fatty acid profile were not significantly affected by the dried mulberry pulp in the diet. Conclusions. As a result, it may be stated that adding dried mulberry pulp up to 8% of the diets of laying quail does not cause any adverse effects and may be used without any problems.

Amaç: Bu çalışmada, İvesi koyunlarına ait dış yapı özellikleriyle osteometrik verileri arasındaki korelasyonların belirlenmesi amaçlandı. Gereç ve Yöntem: Çalışmada 100 dişi, 50 erkek olmak üzere toplam 150 baş İvesi koyun (18-20 aylık yaşta) kullanmıştır. Koyunlara ait cinsiyet, vücut ağırlığı, cidago yüksekliği, sırt yüksekliği, sağrı yüksekliği, sağrı genişliği ve sağrı uzunluğu, sternum yüksekliği, vücut uzunluğu, incik çevresi, bicostal çap, göğüs çevresi ve pelvis genişliği ölçümleri alındıktan sonra DR sistemli dijital mobil röntgen cihazı ile metapodiumların radyografileri alındı. Bulgular: Metapodiumlara ait radyometrik ölçüm değerleri incelendiğinde; metacarpus’ da GL, Bp, SD, Bd, Be, WCL; metatarsus’ da ise GL, Bp, SD, Bd, Be, WCM, WCL ve CM değerleri arasında istatistiksel olarak önemli düzeyde sexuel dimorfizm belirlendi (p < 0.001). Metapodial radyometri ile dış yapı özellikleri arasında korelasyon incelendiğinde ön bacak için en yüksek korelasyon değeri metacarpal kemiklerin radyometri ölçümlerinden GL değeri ile dış yapı ölçüm değerlerinden sırt yüksekliği arasında bulunmuştur (r: 0.684). Arka bacak için en yüksek korelasyon değeri metatarsal kemiklerin radyometrik ölçümlerinden SD değeri ile dış yapı ölçüm değerlerinden sırt yüksekliği arasında bulunmuştur (r: 0.679). Öneri: Gelişimini vücutta erken tamamlayan metapodiumların vücut ölçümleri arasında kuvvetli ilişkiler tespit edildi. Çalışmadan elde edilen sonuçlar büyüme ve et verimi yönünden yapılan seleksiyon çalışmalarında metapodial radyometrik özelliklerin kullanım potansiyeli olduğunu göstermektedir.
