Turkish Journal of Veterinary & Animal Sciences

The possible pharmacological and toxicological effects of Pistacia terebinthus L. in experimentally hypercholesterolemic rabbits were investigated in this study. A total of 28 rabbits were divided into four groups, and these groups were fed diets containing standard pellets (Group 1), cholesterol (2%) (Group II), P. terebinthus L. (1 g/kg body weight) and cholesterol (2%) (Group III) and P. terebinthus L. (1 g/kg body weight) (Group IV) for 14 weeks. When the data were statistically evaluated over the weeks, body weight gains, showed no marked difference among the groups although liver weight was 58% higher in the cholesterol control group (P < 0.01) and 20.3% higher in P. terebinthus L. and cholesterol group than in the control group. In the comparison of the cholesterol-fed groups, Group III exhibited a marked decrease (P < 0.01) in total cholesterol and triglyceride evels and very low density lipoprotein (VLDL) and low density lipoprotein (LDL) levels by the 14th week and a 1.3-times higher (P < 0.001) high density lipoprotein (HDL) value. In the group fed cholesterol and P. terebinthus L., clotting and bleeding times increased by 13% and 12%, respectively, compored to the cholesterol control group. On account of the histopathological findings, it was confirmed that P. terebinthus L. restrained the progression of the atherosclerotic lesions in the thoracic artery and of hydropic degeneration and fatty changes in the liver. No toxic effect could be attributed to P. terebinthus L. from an investigation of the biochemical data. The results of this study show that P. terebinthus L. has a hypolipidemic effect in hypercholesterolemic rabbits.

Turkish Journal of Veterinary & Animal Sciences

The objective of this study was to evaluate the effects of different combinations of energy (barley and dried molassed sugar beet pulp (DMSBP)) and protein sources (soybean meal (SBM), cotton-seed meal (CSM), SBM-treated with formaldehyde (FTSBM), CSM-treated with formaldehyde (FTCSM), and urea) on some rumen fluid and blood parameters. In this study, four rumen fistulated Morkaraman rams were used. Rumen pH values were around the optimal pH values suggested for rumen fluid (5.2-7.3) at all sampling times. Ruminal NH_3-N concentrations were significantly greater (P < 0.05) in animals fed DMSBP as an energy source compared with animals fed barley as an energy source and were between 10.4 and 32.75 mg/100 ml in all groups. Formaldehyde treatments of protein sources reduced ruminal NH_3-N concentrations in animals fed DSBP as an energy source (P < 0.05). Acetic and propionic acid concentrations were affected by the energy source, although butyric acid concentrations were significantly higher in animals fed groups containing barley than in animals fed groups containing DMSBP. Formaldehyde treatment did not affect propionic acid concentrations, although propionic acid concentrations were generally significantly higher (P < 0.05) in animals fed barley + SBM combinations compared to treatments containing both SBM and CSM combinations (P < 0.05). Serum total protein concentrations were affected by the energy source and these were higher in groups containing DMSBP than in groups containing barley (P < 0.05). However, serum urea-N concentrations were similar among the different diets.

The fatty acid (FA) composition of some tissues of Salmo trutta labrax, Pallas, 1811 mature native freshwater wild salmon species caught from Kazandere creek in the Çoruh region in Turkey were investigated. Fatty acids profiles of muscle, liver, gonad, egg and adipose tissue were compared in terms of total and individual saturated and unsaturated fatty acids. The results showed that the highest total saturated fatty acid content was in the muscle (37.20 ± 1.13%) while the lowest value was in the egg (27.12 ± 2.53%), and the differences were significant (P < 0.05) among the tissues. Monounsaturated fatty acid contents (MUFA) were not significantly different (P > 0.05) for the tissues but n-3 polyunsaturated fatty acid …
