Evaluation Of The Photocopy Method For Counting Puntius Conchonius’S Eggs, Şehri̇ban Çek, Mahmut Ali̇ Gökçe Jan 2005

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.

The selectivity of 3 trawl codends, (1) a commercially used standard codend, (2) a narrow codend (100 meshes on its circumference instead of 200) and (3) a square mesh top panel codend, was tested for hake (Merluccius merluccius) and poor cod (Trisopterus minutus capelanus) between 8 and 24 October 2003, in the Aegean Sea. Data were collected using the covered codend technique, and analysed by means of a logistic equation with the maximum likelihood method. The results show that the commercially used standard codend (40 mm mesh size PE codends, 200 meshes on its circumference) retains all the hake that …

Rapid Evaluation Of Bacteriolysis Of Listeria Innocua And L. Welshimeri Strains Isolated From Foods, Fi̇gen Çeti̇nkaya, Recep Çibik

Turkish Journal of Veterinary & Animal Sciences

This study was performed to determine the bacteriolytic extent of 10 strains of Listeria innocua and 9 strains of L. welshimeri isolated from foods. Bacteriolysis was measured at 650 nm by spectrophotometer. For this purpose, late exponential phase cells were transferred into potassium phosphate buffer (100 mM, pH 7.0) and incubated at 37 ºC. While the bacteriolysis range of L. innocua strains was 48% to 76% after 48 h of incubation, L. welshimeri isolates exhibited broader bacteriolytic variabilities, from 10% to 67%. A preliminary analysis of the bacteriolysis of L. innocua and L. welshimeri may be useful in detailed evaluations …
