Effects Of Ascorbic Acid On The Performance And Some Blood Parameters Of Japanese Quails Reared Under Hot Climate Conditions, Mehmet Avci, Muğdat Yertürk, Oktay Kaplan
Turkish Journal of Veterinary & Animal Sciences
The effects of ascorbic acid on the performance and some blood parameters of Japanese quails reared under hot conditions were investigated. Three hundred Japanese quails, 7 days of age, were randomly divided into one control and two experimental groups, comprising five replicates of 20 birds each. Ascorbic acid (500 and 1000 mg/kg) was given to the experimental groups. The body weight gain increased significantly (P < 0.05) in the group given 500 mg/kg of ascorbic acid until the fourth week. Feed consumption also increased (P < 0.05), depending on the quantity of ascorbic acid supplementation until the fourth week. However, ascorbic acid did not affect the concentrations of blood pH, PCO_{2}, sodium (Na), potassium (K), hematocrit (PCV), bicarbonate (HCO_{3}), or hemoglobin (Hb). In conclusion, 500 mg/kg of ascorbic acid may be added to the quail diet to prevent heat stress until the fourth week.

Efficacy Of Tribasic Copper Chloride (Tbcc) To Reduce The Harmful Effects Of Aflatoxin In Broilers, Sefa Çeli̇k, Zeynep Erdoğan, Suat Erdoğan, Ramazan Bal
Turkish Journal of Veterinary & Animal Sciences
This study was conducted to evaluate the effects of copper as tribasic copper chloride on serum biochemical values and growth performance of broilers intoxicated with aflatoxins. Aflatoxins significantly decreased the level of albumin (P < 0.001), total protein (P < 0.001) and total cholesterol (P < 0.01), and increased the activities of alanine amino transferase, L-lactic dehydrogenase and alkaline phosphatase (P £ 0.001) in serum. These AF-induced changes were significantly improved by adding tribasic copper chloride to the diet. The decrease in serum copper concentration induced by aflatoxin was reversed by tribasic copper chloride. Serum zinc concentrations were not affected in tribasic copper chloride and tribasic copper chloride plus aflatoxin groups. Serum iron levels decreased in all the treatment groups significantly (P < 0.05). Aflatoxins caused significant decrease in the body weight gain and significant increase in the feed conversion ratio. Adverse effects of aflatoxins on feed conversion ratio were reversed by tribasic copper chloride supplementation to the diet. It is suggested that tribasic copper chloride might be used for reducing the adverse effects of aflatoxins in broiler production.

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
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.

Total ammonia nitrogen excretion rates were measured in Black Sea turbot (averaging 88.8 g) to compare the protein quality of prawns, the natural food of turbot, with that of the protein source commonly used in the feed industry, i.e. anchovy meal. Two different prawn species (Baltic prawn, Palaemon adspersus, and rockpool prawn, Palaemon elegans) were offered to fish as wet feed at 17.5 ± 0.5 ºC and a salinity of 17 ppt. Furthermore, for determination of the effects of wet feed and dry feed on the peak times of ammonia nitrogen excretion rates, another experimental group of fish was offered …

In this study, 212 Acanthobrama marmid Heckel, 1843 individuals were caught at monthly periods from Keban Dam Lake between January 1997 and December 1998 and transported live to the laboratory. After haematological analysis was carried out on the blood samples taken from their hearts, total lengths and weights were measured. The sex of the fish was identified and their ages were determined from the scales. The total amounts of erythrocytes, leucocytes, thrombocytes, haemoglobin and haematocrits and MCV, MCH and MCHC parameters were determined from blood samples. The formulae of leucocytes were examined from blood preparations of each sample. The distributions …
