Turkish Journal of Veterinary & Animal Sciences
Rainbow trout Oncorhynchus mykiss with an initial mean weight of 174 g (1+ year old) were fed on 3 different commercial diets (1 extruded pellet and 2 steam pellet) in the same environmental conditions until their first spawning. Changes in growth performance (weight gain, condition factor, specific growth rate and feed conversion rate), gonadosomatic index (GSI), hepatosomatic index (HSI) and body composition (protein, lipid, ash and dry matter) were investigated. The mean weight gain and condition factor for fish fed the extruded diet was significantly greater than for those fed the steam pellet diets (P < 0.05 ). There were no significant differences in specific growth rate, mean length increments and feed conversion rate among the groups, although the feed conversion rate for the extruded diet was slightly lower than the others. The HSI of the group fed an extruded diet was significantly greater than those of the others ( P < 0.05 ). The GSI values of female and male fish at the end of the study (October) did not differ significantly among the groups. Similarly, diet had no significant effects on the muscle composition of the trial fish, except that the muscle lipid of the group fed the extruded diet was significantly higher than those of the other groups (P < 0.05).

Growth And Carcass Characteristics Of Three Fat-Tailed Pure Breeds Under Grazing With Concentrate Supplementation, Muhli̇s Maci̇t, Sirri Şahi̇n, Nuri̇ni̇sa Esenbuğa, Mevlüt Karaoğlu
Turkish Journal of Veterinary & Animal Sciences
Growth performance, carcass measurements and carcass characteristics of three fat-tailed Turkish breeds (Awassi = A, Morkaraman = M and Tushin = T) weaned at 2.5 months of age and subjected to semi-intensive feeding during a grazing period on pasture for 70 days were evaluated. At the end of the 70-day grazing period, M lambs showed the highest performance for daily weight gain and the amount of concentrate consumed per bodyweight gain in addition to grazing on pasture. The effects of the breed and sex of lambs on daily weight gain on pasture were significant (P < 0.05) and highly significant (P < 0.01), respectively. Male lambs were superior to female lambs with respect to daily weight gain on pasture. The slaughter traits, carcass measurements and carcass characteristics of 14 male lambs representing three fat-tailed breeds were compared at the end of the grazing period of the year in which they were born. After slaughter, carcasses were chilled at +4 °C for 24 h and measurements were taken on the intact cold carcasses. The carcasses were then dissected into wholesale cuts. The hot carcass weight and hindshank weight of M lambs were heavier than those of A and T lambs. M had a higher hot dressing percentage and larger M. longissimus dorsi (LD) area than those of A and T lambs. Most of the weights of wholesale cuts such as foreshank and breast, sirloin, leg, rib and hindshank were significantly (P < 0.05; P < 0.01) affected by sheep breed. It is recommended either that A, M or T male and female lambs weaned at 2.5 months of age in eastern Turkey should be fed with 450 g concentrate per head per day on pasture for 3 to 3.5 months of grazing season, or lambs should be supplemented with more than 450 g concentrate feed on pasture because native fat-tailed Turkish breeds supplemented with 450 g concentrate on pasture did not give carcasses with an adequate commercial weight at the end of a 70-day fattening period.

Behaviour And Biological Control Of Bacteriocin-Producing Leuconostocs Associated With Spoilage Of Vacuum-Packaged Sucuk, Özlem Osmanağaoğlu
Behaviour And Biological Control Of Bacteriocin-Producing Leuconostocs Associated With Spoilage Of Vacuum-Packaged Sucuk, Özlem Osmanağaoğlu
Turkish Journal of Veterinary & Animal Sciences
Non-motile, Gram-positive and catalase-negative anaerobic Leuconostoc sp. were found to be involved in the spoilage of vacuum-packaged refrigerated sucuk samples. The spoilage was associated with an accumulation of large quantities of foul-smelling gas and purge in the bag and loss of colour and texture in the meat. Many of these isolates produce bacteriocins, to which the predominant Gram-positive bacteria normally found in these products are sensitive. As the leuconostocs grew at low temperatures and produced bacteriocins, they inhibited the growth of associated sensitive bacteria. Attempts to inoculate purge from spoiled samples into fresh meat, vacuum packaging and refrigeration storage facilitated …

Turkish Journal of Veterinary & Animal Sciences
In this study some blood parameters and the effects of age, sex, housing system and pregnancy of Tuj sheep that have been bred in the Kars region of Turkey were researched and compared. The various blood parameters including the amount of haemoglobin, haematocrit value, erythrocyte and leukocyte count, and the differential percentage of white blood cells were determined from blood taken intravenously. The haemoglobin and erythrocyte values were found to be significantly (p < 0.05) higher in 5-7-month-old Tuj sheep grazing in an open field than in 2-3-month-old male Tuj sheep feeding in a closed system. The erythrocyte count was found to be higher in 2-3-month-old female Tuj sheep in comparison to males. The haemoglobin, leukocyte and haematocrit values were also higher in this group of animals, though this was not statistically significant. The erythrocyte, leukocyte, haemoglobin, haematocrit values and differential percentage of white blood cells were not different in 5-7-month-old male and female Tuj sheep grazing in an open area. The erythrocyte number decreased after parturition in respect to the oestrus and pregnancy period. This decrease was statistically significant. The erythrocyte values were 10.2 x 10^6 /mm^3 before oestrus, 9.5 x 10^6 /mm3 during pregnancy and 8.2 x 10^6 /mm^3 after parturition. The haemoglobin value decreased significantly (p < 0.05) during pregnancy. The leukocyte number was found to be less during pregnancy in comparison to other periods; it was 7.7 ± 1.9 x 10^3 /mm^3 during pregnancy, 9.3 ± 1.9 x 10^3 /mm^3 before oestrus, and 9.7 ± 2.5 x 10^3 /mm^3 after parturation. The lymphocyte percentage increased significantly (p < 0.05) during the pregnancy period.
