Abstract. The anesthetic efficacy of two kinds of natural anesthetic Clove (Eugenia caryophyllatata) and Tobacco (Nicotiana tabacum) powders were evaluated on common carp (Cyprinus carpio L.) for handling and health management experiments. The concentrations of anesthetics were assessed by using two types of clove and tobacco anesthetics; each with three replicates for measuring induction times to anesthesia. Concentrations of 100, 200, 250, and 350 mg/l at the ratio 1:1 of the aqueous extract of both Clove (Eugenia caryophyllatata) and Tobacco (Nicotiana tabacum) to evaluate their effect on common carp anesthesia were used. The aqueous extract anesthetized fish partially in the high levels. No significant differences appeared on blood glucose, ALP, ALT and AST among different levels of the anesthesia concentrations used. As the anesthesia concentration increased, the Red blood cell (RBC) count and hemoglobin decreased.

Abstract. In this study, the effect of the diets enriched nutritionally with whey powder (WP) on the growth and development of weaned Saanen Goat kids was investigated. For the purpose, 24 kids born in March 2017 and weaned after 5 months and reared for 8 weeks in Adnan Menderes University Agricultural Faculty Research and Application Farm were used. The kids were divided into three groups according to the content of the ration. The kids whose beginning weights were recorded were distributed homogeneously to each group. These groups were labeled as the control group (CG) and the experimental groups which were formed by adding 5% (5%WP) and 10% whey powder (10%WP) to the ration by removing the same amount of feed. The following parameters of the experimental kids were controlled: live weight, body condition score (BCS), body length, chest girth, the height at the withers, and some blood serum indices (total protein, cholesterol, glucose and urea). The differences between the initial and final values of the growth performance parameters in the groups with the best improvement according to the results obtained from the experiment were found to be 2.57 kg in body weight and 6.25 cm in body length in 10%WP group and the body condition score was 0.26 points, wither height 6.06 cm, and chest girth 6.75 cm in the 5%WP group. When the groups in which the best results are observed in blood parameters are considered; in the 5% WP group, the difference between the initial and final values were found to be 4.19 mg/dL in glucose and 1.22 g/dL in total protein, while urea 41.06 mg/L and cholesterol were determined to be 58.53 mg/dL in the 10%WP group. In the light of the results obtained, it has been determined that the addition of WP in a certain amount to the ration has a positive effect on the growth and development of the kids. As a result of the study, the addition of 5%WP was recommended in the ration to be given during the kid growing period.

Abstract. A physiological experiment was conducted with three yearling sheep, Stara Zagora x Pleven Blackhead crosses, to establish the effect of feeding Paulownia elongatа leaves on some blood parameters. The trial consisted of two periods: control and experimental. During the control period, yearling sheep were fed a ration of 1 kg barley and 1 kg meadow hay, and during the experimental period – dried Paulownia elongatа leaves. Blood samples were collected from v. jugularis externa before feeding and 2.5 hours after feeding during both periods after allowing 10-day adaptation to the respective diet. The studied parameters were erythrocyte counts, leukocyte counts, blood glucose, total protein, albumin and globulins. The intake of Paulownia leaves resulted in statistically significant reduction in erythrocyte (p<0.05) and leukocyte counts (p<0.001). This was most pronounced in the postprandial hours. Paulownia leaves also provoked increased total serum protein concentrations on the account of both higher albumin and globulins. The albumin/globulin ratio was 0.29 regardless of the type of diet or the time of sampling – prior to or after feeding.
