Environmental Factors Affecting Milk Yield And Fertility Traits Of Simmental Cows Raised At The Kazova State Farm And Phenotypic Correlations Between These Traits, Süleyman Çi̇lek, Mehmet Emi̇n Teki̇n
Turkish Journal of Veterinary & Animal Sciences
The aim of this study was to investigate environmental factors affecting milk yield and fertility traits of Simmental cows raised at the Kazova state farm and the phenotypic correlation between these traits from 1473 records between 1992 and 2001. The least square means of 305-days milk yield, lactation duration, dry period, service period, calving interval, gestation length and number of inseminations per conception (NIPC) were 4700 kg, 300 days, 81 days, 94 days, 379 days, 283.6 days and 1.76, respectively. The effect of calving year on milk yield and fertility traits was statistically significant (P < 0.001). The effect of calving age on gestation length and milk yield was also statistically significant (P < 0.001-P < 0.05). The effect of calving season on gestation length, 305-days milk yield and NIPC was also statistically significant (P < 0.001-P < 0.05). Birth type did not significantly affect any traits, except for gestation length. The phenotypic correlations between 305-days milk yield and lactation duration (0.39), between NIPC and service period (0.81), between NIPC and calving interval (0.77), between calving interval and service period (0.96) and between calving interval and gestation length (0.12) were statistically significant (P < 0.001). Correlations between milk yield and fertility traits (0.09-0.77) were statistically significant (P < 0.001-P < 0.05), except for gestation length. These results are acceptable and it can be concluded that Simmental cattle are raised successfully on this farm and under Turkish conditions.

Turkish Journal of Veterinary & Animal Sciences
The effect of a bacteriocin-producing strain, Lactobacillus sakei Lb706, on the behavior of Listeria monocytogenes in rainbow trout fillets stored under vacuum at 4 ºC for 14 days and at 10 ºC for 5 days was investigated. At 4 ºC, growth of L. monocytogenes was significantly inhibited (P < 0.05) by L. sakei Lb706 during 10 days of storage while bacteriocin-negative Lb706-B did not affect the growth of L. monocytogenes during 14 days of storage. In the presence of the sakacin A-producing strain of L. sakei (Lb706), the growth of L. monocytogenes was significantly inhibited (P < 0.05) in the first 3 days of storage at 10 ºC, after which its count increased to 10^7 CFU/g. The control group and the group containing L. sakei Lb706-B showed similar growth patterns of L. monocytogenes. Significant increases (P < 0.05) were observed in all groups in terms of psychrotrophic bacteria counts. No significant (P > 0.05) changes in pH values during storage at 4 ºC and 10 ºC were determined. Consequently, the results of the present study showed that L. sakei Lb706 can be used as a protective culture in freshwater reared rainbow trout, especially for preventing possible contaminations of Gram-positive food-borne pathogenic bacteria such as L. …

Turkish Journal of Veterinary & Animal Sciences
Changes in branchial Na^+-K^+-ATPase activity, and the number and size of chloride cells resulting from the transfer of fish into seawater were investigated in tilapia (Oreochromis niloticus) (22.03 -+ 0.91 g), which were transferred to full strength seawater (36‰) directly and for 14 days. Whole mortality occurred when the tilapia were transferred into seawater directly. That is, no acclimation was allowed. Branchial chloride cell numbers decreased after seawater exposure, whereas a gradual increase was observed in chloride cell sizes. However, the chloride cells of seawater-adapted individuals showed a 2-fold increase in size (P < 0.05). Initially 5‰ and 10‰ salinity resulted in lowered branchial Na^+-K^+-ATPase activity but then this activity increased and the highest activity was at 25‰ salinity (P < 0.01). This study demonstrated the effects of high salinity through direct and gradual acclimations on branchial Na^+-K^+-ATPase activity and chloride cell abundance.
