The Effects Of Electrical Stimulation On The Sensory And Textural Quality Properties Of Mutton Carcasses, Mete Yanar, Hasan Yeti̇m

Turkish Journal of Veterinary & Animal Sciences

The objective of this research was to investigate the influence of electrical stimulation (ES) on the sensory and textural quality characteristics of mutton carcasses from elderly ewes. For this purpose, 14 ovine carcasses from 3-5-year-old ewes were subjected to ES with 350 V, and the effects of ES on the organoleptic and instron textural parameters were evaluated. The ES significantly (P < 0.01) improved the panel tenderness scores of the Longissimus dorsi (LD) muscle. Some of the Instron Warner Bratzler Shear parameters such as peak force and initial yield force values of the LD muscle were also highly significantly (P < 0.01) affected by ES, while the Semimembranosus (SM) muscle was not affected. Hardness and peak force 2 values of LD obtained from the Instron compression test were also significantly (P < 0.05) affected by ES. However, Instron compression parameters of SM muscles were not significantly influenced by ES treatment. The results revealed that the ES could considerably improve the tenderness of the LD from mutton carcasses. In conclusion, the application of ES to mutton carcasses from elderly ewes could be beneficial for the meat industry by increasing the merchandising value and quality of this sort of carcass.

Glycobiology Current Molecular Biology, Sabi̇re Karaçali Jan 2003

Glycobiology Current Molecular Biology, Sabi̇re Karaçali

Turkish Journal of Veterinary & Animal Sciences

Carbohydrate chemistry evolved into carbohydrate biochemistry and gradually into the biology of carbohydrates, or glycobiology, at the end of the last century. Glycobiology is the new research area of modern molecular biology, and it investigates the structure, biosynthesis and biological functions of glycans. The numbers, linkage types (\alpha or \beta), positions, binding points and functional group differences of monosaccharides create microheterogeneity. Thus, numerous glycoforms with precise structural differences occur. Each glycoform as a distinct biological ligand has a different function. Studies in glycobiology have concentrated on determining molecular structures and glycosylation mechanisms, investigating biological control mechanisms and the phenotypic characteristics …

In our study, malondialdehyde, antioxidant vitamins, antioxidant substances and some hematologic-biochemical parameter levels in nephrotoxicosis were investigated. Six dogs were used in the study. Blood samples taken before the experiment were used as the control. Blood samples were taken on days 2, 5, 7 and 10 during the experiment. During analysis, we found that the statistical changes were not significant in the retinol and Vitamin C levels of the experiment group when compared to those of the control group. \beta-carotene (P < 0.05) and Vitamin E (P < 0.001) levels were significantly decreased. Increases in the levels of malondialdehyde, seruloplasmin and urine \gamma-glutamyl transferase (GGT) enzyme were P < 0.001, while decreases in the amounts of glutathione were P < 0.001. We also found that changes in erythrocyte and hemotocrit levels were not significant. On the other hand, increases in the levels of leucocyte (P < 0.01), creatinin and blood urea nitrogen (BUN) P < 0.001 were significant. In conclusion, oxidative damage can occur in cells in nephrotoxicosis, the use of antioxidants could be of benefit during treatment with chemotherapeutics.

The effects of replacing fish oil with soybean oil, sunflower oil, corn oil and olive oil in starter feeds on the vicerosomatic index, hepatosomatic index and liver fatty acid composition of the sea bass were studied. Juvenile sea bass (initial weight = 7.58 ± 0.13 g) were fed experimental diets for 75 days. The fish were then killed and liver samples were collected. The lowest total crude fat value (17.61%) was found in the fish fed the fish oil diet. The highest total crude fat value (34.30%) was found in the fish fed the olive oil diet (P < 0.05). Similarly, the fish fed the fish oil diet had the lowest hepatosomatic index value (2.08) and all the fish fed vegetable oils had similarly high hepatosomatic index values (P < 0.05). Likewise, vicerosomatic index values were lowest (9.06%) in the fish fed fish oil and highest in the fish fed soybean and other vegetable oils (P < 0.05). Fatty acid analyses showed that EPA and DHA from n-3 HUFA's in the fish fed the fish oil diet, linolenic acid (18:3n-3) and linoleic acid (18:2n-6) in the fish fed the soybean oil diet and oleic acid (18:1n-9) in the fish fed the olive oil diet were higher than in the fish fed the other diets.

In this research, the effects of some alternative feed additives for antibiotic growth promoters on performance and gut microflora were examined using 500, one-day-old Ross 508 broiler chicks. Commercial corn-soy-based broiler starter and finisher diets were formulated as basal diets for control treatment. Basal diets were supplemented with an antibiotic growth promoter, a probiotic, a prebiotic (mannan oligosaccharide) and a humic-acid-based mixture, respectively. It total, five dietary treatments were employed in the experiment. Live weight, weight gain and feed consumption values were not affected significantly by dietary treatments throughout the experiment (P > 0,05). However, chicks which received diets supplemented with …

In this study, the effects of food supplemented with different levels of DL-alanin and L-glutamic acid (1% and 2%) on the growth of sea bass juveniles were investigated. Fish fed with L-glutamic acid (1% of diet) and DL-alanin (1% of diet) supplemented diets had greater weight gains (54.23 ± 1.51 g and 55.03 ± 1.69 g, respectively) than those fed with a control diet (47.59 ± 1.83 g) (p < 0.05). It was found that the groups fed with 1% of attractant-supplemented diets had better food conversion ratios (1.11 and 1.13, respectively) than the control group (1.22) (p < 0.05). It was also found that the wet weight gain and food conversion ratios of the groups fed with 2% L-glutamic acid and DL-alanine were similar to those fed with the control diet and 1% attractant-supplemented diets (p > 0.05).
