Functional Analysis Of Age-Weight Gain And Age-Feed Consumption In Brown Swiss And Holstein Calves, Ömer Akbulut, Bahri̇ Bayram

Turkish Journal of Veterinary & Animal Sciences

This research was carried out to determine the amount of concentrate and hay consumed during the milk feeding period and the weaning age of Brown Swiss and Holstein calves. Twenty-five Brown Swiss and twenty Holstein Friesian calves were used. Calves reached 500 g and 1000 g/daily calf starter feed consumption at 36.5 ± 1.8 and 53.8 ± 1.2 days-old respectively. Also, gains in live weight and daily feed consumption depending upon age were studied functionally.

Turkish Journal of Veterinary & Animal Sciences

The aim of this study was to determine the prevalence of paratuberculosis in dairy cattle in ElazİÛ and the surrounding villages. A polymerase chain reaction (PCR) based on IS900, an insertion sequence specific to Mycobacterium avium subsp. paratuberculosis, was used to detect mycobacterial DNA in milk samples of 500 dairy cows. The detection limit of the PCR was assessed by spiking a known negative milk sample with a dilution series (1x10 9 to 10 bacteria/ml) of reference M. avium subsp. paratuberculosis culture). In the agarose gel examination of the PCR amplified products, approximately 50 bacteria/ml were detected. In the examination …

A Morphological Investigation Of The Postnatal Development Of The Syrinx In The Quail, Güner Bayram, Nari̇n Li̇man

Turkish Journal of Veterinary & Animal Sciences

The morphological and structural development of the syrinx was studied with a light microscope in 100 female and male Japanese quails from 1 to 60 days old and adults. The quails had a tracheobronchial syrinx since it was based on both tracheal and bronchial elements. Two tracheal syringeal cartilages were attached at both ends to the pessulus in the tympanum. In this species the tympanum had a slightly increased diameter. The pessulus was a wedge-shaped cartilage, its blade lying dorsoventrally so that it divided the airway vertically. The pessulus examined histologically at 35 and 42 days post-hatching showed marked and …

Evidence That The Neurokinin 1 Receptor Is Expressed In Spinal Neurones Which Do Not Synthesize Nitric Oxide In The Rat, Mümtaz Nazli, Richard Morris

Turkish Journal of Veterinary & Animal Sciences

The co-localization of the distribution of the neurokinin 1 receptor with nitric oxide was investigated in laminae I-II, III- IV, X and in the intermediolateral horn of the spinal cord in thirteen adult rats. Silver-intensified gold and standard immunocytochemical labelling or standard double immunocytochemical labelling were employed in 40µm-thick sections of the spinal cord. There were many NK1 receptor-expressing neurones in the dorsal horn of the spinal cord, but none of these expressed NOS. Although neurones expressing the NK1 receptor and NOS were in close proximity in LX and IML, co-localization of the NK1 receptor and NOS in single neurones …

Turkish Journal of Veterinary & Animal Sciences

Modified tryptic soy broth, lauryl sulfate tryptose broth, modified EC broth, sorbitol MacConkey agar and Fluorocult E. coli O157 agar were tested for the recovery of 3 strains of Escherichia coliO157:H7 against E. colitype 1 and Citrobacter freundii as common competitive microflora of raw meat products. Two-stepped trials showed that modified EC broth and lauryl sulfate tryptose broth were superior to modified tryptic soy broth as selective enrichment media while sorbitol MacConkey agar was clearly better than Fluorocult E. coli O157 agar as a selective agar medium. Recovery of E. coli O157:H7 was difficult when selective enrichment broth-growing cohabitant microflora …

Cost Of Mastitis In Scottish Dairy Herds With Low And High Subclinical Mastitis Problems, Cengi̇z Yalçin

Turkish Journal of Veterinary & Animal Sciences

The aim of this study was to estimate the cost of mastitis and the contribution of each cost component of mastitis to the total mastitis induced cost in herds with low and high levels of subclinical mastitis under Scottish field conditions. It was estimated that mastitis cost £140 per cow/year to the average Scottish dairy farmer in 1996. However, this figure was as low as £69 per cow/year in herds with lower levels of subclinical mastitis, and as high as £228 cow/year in herds with high sub- clinical mastitis. The magnitude and proportion of the cost components in the total …

Turkish Journal of Veterinary & Animal Sciences

A number of recent studies suggest the effects of several growth factors as well as genetic factors on the development and differentiation of the testes and excretory ducts. One of the most important growth factors affecting the development and differentiation of the above-mentioned organs may be epidermal growth factor (EGF). Therefore, the aim of the present study was to investigate the effects of EGF on the development of the testes and excretory ducts of male rats by determining the immunolocalization of EGF receptors in these organs during foetal and postnatal periods. To do this, testicular and excretory duct tissue samples …

Turkish Journal of Veterinary & Animal Sciences

The effect of halothane anesthesia in different doses and a period of two weeks on glucose-6-phosphate dehydrogenase (G6PDH) activity of mouse liver were investigated. The mean and SD of G6PDH for liver of normal mice were 0.036±0.017 U/mg protein and 1.756±0.814 U/g liver, respectively. Although there was histopathological damage in the liver, liver weights in treated mice increased significantly compared to control animals. Increasing the dosage of halothane inhalation induced liver G6PDH enzyme activity (U/g liver) by 84%, 42% and 4%, showing an inverse relation with the dose of halothane (0.25, 0.50, 1.00 cc twice daily for two weeks).

A Study On The Effects Of Chilling On The Microbiological Quality Of Poultry Carcasses And Surface Decontamination With Lactic Acid, Hali̇l Tosun, Abdurrahman Üsame Tamer

Turkish Journal of Veterinary & Animal Sciences

Effects of immersion chilling on the microbiological quality of poultry carcasses and cross contamination of Salmonella were studied. Levels of aerobic mezophilic bacteria, coliform, Escherichia coli and the incidence of Salmonella were determined prechill and postchill. The level of coliform and E. coli were reduced by immersion chilling (P0.05) but there was an increase in Salmonella incidence in carcasses exiting the immersion chiller indicating that this may be the point of most significant cross contamination in broiler processing plants. Experiments on microbial decontamination of poultry carcasses with lactic acid were performed. The microbial levels of poultry carcasses were reduced significantly …

Turkish Journal of Veterinary & Animal Sciences

In this study, the monthly variation in the blood glucose level of Capoeta capoeta capoeta caught from Aras between August 1995 and June 1996 was determined. The average blood glucose level was determined to be 112.04±5.19 mg/dl in males and 106.32±9.68 mg/dl in females and 110.06±4.19 mg/dl in the population. The blood glucose level was highest (141.07±13.67 mg/dl) in April, and lowest (69.14±9.75 mg/dl) in September. It was deter- mined that the level of blood glucose was related to temperature and reproduction.
