Effects Of Egg Weight And Length Of Storage Period On Hatchability And Subsequent Laying Performance Of Quail, Meti̇n Petek, Hasan Başpinar, M. Mustafa Oğan, Faruk Balci

Turkish Journal of Veterinary & Animal Sciences

This study was carried out to investigate the effects of hatching egg weight and length of egg storage period on hatchability and subsequent laying performance of quails. Eggs were collected from a quail flock (Coturnix coturnix Pharaoh) aged 17 weeks and classified into 4 groups on the basis of storage period 1, 3, 5, or 7 d. Prior to egg storage, the eggs in each group were further divided into egg weight treatment (small: 12.51 g). Hatchability of total and fertile eggs was affected significantly by hatching egg weight (P < 0.05) but was not affected significantly by the length of egg storage period. There was a decrease in egg production associated with increase in hatching egg weight. Egg production of quails hatched from stored eggs for 3 days was greater than the other groups. There was a significant interaction between hatching egg weight and length of egg storage for egg production. It was concluded that medium eggs can be hatched satisfactorily after 3 days storage for optimum egg production in quails.

Some Behaviour Traits Observed On The Kıvırcık And Crossbred Lambs Raised In Intensive Conditions, Fevzi̇ Karaağaç, Mustafa Özcan, Türker Savaş

Turkish Journal of Veterinary & Animal Sciences

In this study, the behaviour responses of the crossbred lambs [F_2 (German Black-Headed Mutton x Merino) x F_1 (Chios x Kıvırcık)] were compared with the Kıvırcık lambs in intensive conditions and the effects of genotype, sex and observation period on the behaviours displayed were investigated. The data were collected from 10 (5 male + 5 female) Kıvırcık and 10 (5 male + 5 female) crossbred lambs, which were weaned at the age of 2-2.5 months. The effect of genotype was found significant on the behaviours of feed consumption (P < 0.01), activities towards the bedding material (P < 0.05), rumination (P < 0.01), lying (P < 0.01), oral stereotypic behaviours (OSB) (P < 0.01) and behaviours towards animal (BTA) (P < 0.01). Behaviours towards other animals and oral stereotypic behaviours in the crossbred lambs were 50% and 27% more than the Kıvırcık lambs, respectively. Significant differences in terms of the activities towards the bedding material (P < 0.05), rumination (P < 0.01) and lying (P < 0.01) behaviours were determined between the male and female lambs. It was seen that the male lambs were more active in the breeding area. The effects of observation period were found significant on feeding (P < 0.01), drinking (P < 0.01), rumination (P < 0.01), lying (P < 0.01), standing (P < 0.01), oral stereotypic behaviours (P < 0.01) and behaviours towards animals (P < 0.05). Although the crossbred lambs were more superior for fattening program in terms of live weight gains, they showed more abnormal behaviours (OSB and BTA), which are the signs of stress, in the limited breeding area, depend on the lessening of the area by the rise in their live weights.

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.

Honeybee colonies from Turkey, Naxcivan (Azerbaijan) and Austria were studied for morphometric and electrophoretic variation and for comparison among different subspecies. Out of six enzyme systems, four were found to be polymorphic with 14 allozymes. Discriminant function analysis of 10 morphometric variables resulted in a total of four groups. Cluster analysis of electrophoretic data showed a similar type of groupings. Among the four polymorphic loci, Mdh-1 showed the highest and Est-3 the lowest differentiation among populations.

Turkish Journal of Veterinary & Animal Sciences

This study was carried out to isolate Clostridium perfringens from chickens and to detect the gene encoding the alpha toxin produced by all types of C. perfringens by polymerase chain reaction (PCR). Intestinal contents of 160 slaughtered chickens from 8 different farms in Elazığ province were analyzed. C. perfringens was isolated from 8 (5%) of the samples. DNA samples extracted from suspected isolates grown on selective agar were amplified by PCR using a pair of primers derived from the alpha toxin gene. All of 8 suspected isolates were found to be C. perfringens by conventional methods and PCR. Isolates were …
