Evaluation Of The Photocopy Method For Counting Puntius Conchonius’S Eggs, Şehri̇ban Çek, Mahmut Ali̇ Gökçe

Turkish Journal of Veterinary & Animal Sciences

The photocopy technique was developed to count fish eggs. Fecundity of the rosy barb Puntius conchonius was determined by both actual counts and the photocopy method. Egg stripping and fertilisation were performed manually. After fertilisation, water-hardened eggs were photocopied. White circles were counted and recorded as viable eggs and dark dots counted as dead eggs. Egg numbers estimated by this technique were significantly correlated with those estimated by actual counting (r = 0.999; P < 0.05). The advantage of the photocopy method is that it is a relatively fast method without significant loss in accuracy and it is cheaper than the other currently used methods.

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.

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 …

In this study, carried out between November 2000 and October 2001, the annual spawning period, first maturity length, length frequency distribution and length/weight relationship of Parapenaeus longirostris that inhabit most commonly the Sea of Marmara were investigated. Analysis of the data obtained from this study revealed that although the mature individuals with fully developed eggs were found almost every month throughout the year, the highest gonadosomatic index values were obtained in September, October, December, April and May. The total length at which 50% of the population reaches maturity is calculated to be 9.7 cm. Among the individuals caught, females at …

The aim of this study was to investigate the effect of fenfluramine (FEN) administered at single and repeated doses on brain, stomach and plasma serotonin (5-Hydroxytryptamine, 5-HT) levels in rats. FEN was injected intraperitoneally at single doses (1, 3 and 10 µmol kg^{-1}) and given orally at repeated doses (1.25, 5 and 10 mg kg^{-1}) for 21 days. The tissues and plasma samples were collected 20, 40, 80 and 160 minutes after the single dose administrations and 4 h after the last dose administration in repeated experiments. In addition, the rats treated with the dose of 1.25 mg kg^-1 were …
