(Agricultural Research Communication Centre, 2018) Guney, Mehtap; Erdogan, Sibel; Karsli, Mehmet Akif; Demirel, Murat
The aim of this study was to compare feed intake, nutrients digestibility, protein fractions entering into the duodenum, and ruminal fermentation parameters of sheep fed Medicago sativa (alfalfa) and Prangos pabularia, locally called kerkol hays. In the study three ruminally and duodenally cannulated Morkaraman sheep were used. It was carried out as two periods within a 2x3 crossover experimental design. Daily intake of crude protein (CP) was higher (P< 0.05) in sheep fed alfalfa than those fed kerkol hay. Digestibility of NDF and ADF were lower (P< 0.05) in sheep fed alfalfa hay than those fed kerkol hay (P< 0.05). The percentage of protein escaping ruminal degradation was higher (P< 0.05) in sheep fed kerkol hay (30.73%) than those fed alfalfa hay (15.05%). Ruminal fermentation parameters were similar between groups, except ruminal NH3-N concentration. It is concluded that kerkol hay can be used as forage for sheep feeding.

(Tubitak Scientific & Technological Research Council Turkey, 2015) Eski, Funda; Tasal, Ibrahim; Karsli, Mehmet Akif; Sendag, Sait; Uslu, Baris Atalay; Wagner, Henrik; Wehrend, Axel
The aim of this study was to determine the changes in serum nonesterified fatty acid (NEFA), serum beta-hydroxybutyric acid (beta-HBA), triglycerides, Ca, Na, and other metabolites (bilirubin, glutamate dehydrogenase (GLDH)) in the blood of grazing, healthy goats at the time of parturition. Blood samples were taken weekly from the jugular vein of 11 goats, starting at week 2 antepartum (ap) until week 9 postpartum (pp). NEFA and beta-HBA concentrations increased from week 2 ap to 2 weeks pp. The increase in NEFA level was not significant; however, the beta-HBA levels were higher (P < 0.05) 2 weeks pp compared to the levels at 2 weeks ap. Triglycerides were recorded at maximum levels (P < 0.05) 2 weeks ap, with the lowest concentrations at 3 weeks pp. Bilirubin levels consistently increased up to 7 weeks pp, followed by a decrease. However, these changes were not significant. Similarly, GLDH activities increased until week 8 pp. A significant difference (P < 0.05) was recorded between the 1st week and 8th week pp. Ca and Na levels were lower during the 1st week pp and increased at 3 weeks pp. The results show that there are characteristic alterations of some metabolic blood parameters in goats around the time of parturition, which may be related to physiological changes.

(Tubitak Scientific & Technological Research Council Turkey, 2015) Aldemir, Resit; Bingol, Nuriye Tugba; Karsli, Mehmet Akif; Akca, Ismail
The aim of this study was to compare nutrient content, and in situ protein and organic matter degradation kinetics of Prangos ferulacea (L.) (locally called helis), a naturally growing plant on the top of Mount Artos, with those of alfalfa. P. ferulacea plants used in the study were collected from three different parts of Mount Artos in Van Province over two years. While organic matter content and in vitro organic matter digestibility of P. ferulacea were significantly higher, neutral detergent fiber, acid detergent fiber, and acid detergent insoluble nitrogen contents were significantly lower compared with those of alfalfa (P < 0.01). In general, in situ dry matter, and organic matter and crude protein degradability of P. ferulacea were significantly higher compared with those of alfalfa starting from 6 h of incubation (P < 0.05). Organic matter and crude protein degradability of P. ferulacea was 79.15% and 85.31%, respectively, after 48 h of incubation. By-pass protein content and both organic matter and crude protein degradation rates were similar between samples (P > 0.05). It can be concluded that P. ferulacea has a better nutrient quality compared with even high quality alfalfa based on nutrient contents and digestibility values, and therefore substitution of alfalfa by P. ferulacea in the diet of ruminant animals is feasible.

(Agricultural Research Communication Centre, 2017) Bolacali, Memis; Ozturk, Yahya; Yilmaz, Orhan; Kucuk, Mursel; Karsli, Mehmet Akif
The aim of this study was to determine the effects of genotype and non-genetic factors on the growth traits and survival rates of Turkish indigenous Hair goats (n=63) and their first crosses with Boer bucks (n=91), reared under a semi-intensive management system in the Van province of Turkey. The live weights of the kids at birth and on days 30, 60, 90, 120, 150, and 180 were determined to be 3.64, 8.89, 13.99, 18.97, 23.62, 27.22 and 30.44 kg, respectively. The average daily gains in the pre-weaning, post-weaning and overall periods were 171.09, 136.43 and 148.34 g, respectively. The multiple-birth kids had lower survival rates than the single-birth kids (P<0.01). As a result, it may be recommended to Hair goat breeders in the region to use Boer bucks in cross-breeding in order to ensure a better growth performance from the kids; to apply a sustainable selection program; and to improve management conditions. In addition, the data obtained from this study may be used as a model for designing policies on Hair goat breeding in this region.

(Agricultural Research Communication Centre, 2017) Bingol, Nuriye Tugba; Dede, Semiha; Karsli, Mehmet Akif; Yilmaz, Orhan; Turel, Idris; Yuksek, Veysel
The aim of this study was to determine the effects of Plantago major's (P.major) water extract added into broiler diets at different levels on serum protein fractions. A total of 112 Ross 308 broiler chicks were used in the study. Experiment consisted of control and 3 treatment groups with a 28 chicks within each group. Each experimental group was divided into four subgroups consisting of4 chicks. A basal (control) diet was prepared and three experimental diets were established by addition of P.major into basal diet; P.major 1 (5 g/kg feed), P.major 2 (10 g/kg feed), P.major 3 (15 g/kg feed). Broiler chicks were fed with these diets for 42 days ad libitum. Total protein levels of P.major 3 group were lower than other groups and controls. It was determined that the albumin percentages and levels became decreased in a significant ratio in the P.major 1 and P.major 2, (P<0,05), Alpha 1 globulin percentage and concentration were found significantly high in P.major 2 group than the other groups (P<0.05), Alpha 2 level and percentage in P.major 1 group was seen significantly higher than the control group, the A/G ratio in P.major 1 and P.major 2 was seen significantly lower than the control group. There was no significant difference between groups for beta and gamma globulins as percentage.
Effects of Substituting Barley With Wet Sugar Beet Pulp Silage Prepared With Wheat Bran on Fattening Performance, Carcass Quality of Lambs and Cost
(Kafkas Univ, veteriner Fakultesi dergisi, 2011) Ozturk, Yahya; Karsli, Mehmet Akif; Aldemir, Resit; Bolat, Duran
The objectives of this study were to evaluate the effects of substituting barley with wet sugar beet pulp silage at differing levels on fattening performance, carcass quality and cost. To achieve this objective, a barley based diet (control diet) was prepared. Then, three diets were prepared by substituting 35% (35% WSBPS diet), 70 (70% WSBPS diet) and 100% of barley energy with wet pulp silage (100% WSBPS diet). A total of 48, 6-7 month old, male, Akkaraman lambs were utilized in the study. Lambs were randomly allotted into one of four groups based on initial body weights. Each group was also divided into 4 subgroups with 3 lambs within each subgroup and fed with one of four diets for a period of 75 days. Daily feed intake of each subgroup was determined weekly. All of the lambs were weighed bi-weekly to determine weight gains. Six lambs from each treatment group were slaughtered at the end of the experiment to determine carcass quality. Costs of each kg of diet DM and 1 kg of live weight gain for each diet were calculated. Initial live body weights of lambs fed different diets were similar, ranging from 23.48 to 25.03 kg (P>0.05). Overall daily weight gains of lambs fed different diet were also similar throughout the experiment and were 0.160, 0.182, 0.182, and 0.160 kg for control, 35%, 70% and 100% WPS diets, respectively (P>0.05). Hot and cold carcass weights, carcass tight, leg and loin weights were not statistically different among groups (P>0.05), but back weights were greater in sheep fed 75% WSP diet compared with control (P<0.05). Addition of WSBP silage into diets decreased both costs of diets and 1 kg live weight gain in a linear way. It can be concluded that energy provided by barley can be substituted with energy of WSP silage up to 70% without affecting fattening performance, carcass features and can greatly reduce production cost in lambs based on the results of the present study.
