Effect Of Using Urtica Dioica L. On The Quality Of Turkish Sucuk (Turkish Style Dry Sausage), Muhammet İrfan Aksu
Turkish Journal of Veterinary & Animal Sciences
Urtica dioica L. has become a very important plant, with beneficial effects on human health all over the world. In this study, the possibility of using U. dioica L. as an ingredient in Turkish sucuk was investigated. Turkish sucuk with U. dioica L. was evaluated in terms of its chemical, physical, and sensory attributes. The results showed that the level of U. dioica L. (0%, 1%, 3% and 5%) and ripening period (0, 3, 7, 10 and 14 days) had a significant effect on the moisture, pH, residual nitrite, L* and +a* values of sucuk (p < 0.01). +b* values were affected more by the ripening period (p < 0.01) than by the level of U. dioica L. (p < 0.05). Sensory evaluations showed that the addition of U. dioica L. to sucuk (cooked and uncooked) effected the sensory attributes compared with the control sucuk.

The Effects Of Replacing Fish Oil With Vegetable Oils In Starter Feeds On The Liver Fat Composition Of Sea Bass (Dicentrarchus Labrax L., 1758), Mustafa Yildiz, Erdal Şener
Turkish Journal of Veterinary & Animal Sciences
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.

Turkish Journal of Veterinary & Animal Sciences
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 …

Turkish Journal of Veterinary & Animal Sciences
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).

This study was performed to determine the effects of using 40% and 60% triticale with or without enzyme instead of maize on egg production, feed intake, feed efficiency, egg quality and hatchability in laying quail diets. In this study, a total of 160, 12-week-old Japanese quails (Coturnix coturnix japonica) were used; birds with similar live weight and production levels were divided into five groups of 32 quails. Although using triticale at the rate of 40% and 60% in the diet of laying quails did not affect egg production, hatchability, fertility, egg specific gravity, egg shell thickness, the egg white and …

The gonad histology and spawning pattern of the white grouper (Epinephelus aeneus) were determined from fish sampled from commercial catches. Histological, microscopic and macroscopic techniques were used to examine the ovaries of E. aeneus. A six stage maturity scale based on morphology was proposed to classify ovarian development. The results showed that the white grouper has an asynchronous mode of ovarian development, and the histological study of oocyte development in the white grouper indicated that two types of inclusion, first lipid and then protein, are formed during vitellogenesis. Towards maturation, protein granules and lipid droplets increased in size and number …
