Effects Of Urea Or Urea Plus Molasses Supplementation To Silages With Different Sorghum Varieties Harvested At The Milk Stage On The Quality And In Vitro Dry Matter Digestibility Of Silages, Bi̇lal Keski̇n, İ. Hakki Yilmaz, M. Aki̇f Karsli, Hüseyi̇n Nursoy
Turkish Journal of Veterinary & Animal Sciences
The objective of this study was to evaluate the effects of 0.5% urea and 0.5% urea plus 4% molasses (on weight basis) addition to sorghum silages ensiled using 4 sorghum varieties (Grass II, Grazer, Gözde, and P-988) harvested at the milk stage. Plant materials were ensiled in 1-kg jars and the chemical composition, pH, organic acids, in vitro digestibility (IVDMD) and digestible dry matter yield (DDMY) of the silages were determined. Addition of urea and urea plus molasses to silages increased the crude protein ratio significantly (P < 0.01). However, the addition of urea plus molasses significantly decreased the neutral detergent fiber and acid detergent fiber contents of the silages. Additives significantly increased the pH values of the silages. The addition of urea and urea plus molasses to silages generally did not affect acetic or propionic acid content; however, the butyric acid content of the urea and urea plus molasses groups was higher than that of the control groups. IVDMD of all sorghum varieties decreased with the addition of urea and urea plus molasses. Additives did not affect DDMY. In conclusion, the addition of 0.5% urea and 0.5% urea plus 4% molasses to sorghum silages, harvested at the milk stage, improved the CP content of the silages, but they had no positive effect on silage quality, IVDMD or DDMY.

Immunohistochemical Distribution Of Desmin And Vimentin In The Skin Of Zavot Cattle, Şahi̇n Aslan, Hakan Kocamiş, Mümtaz Nazli, Nurhayat Gülmez
Turkish Journal of Veterinary & Animal Sciences
The distribution patterns of desmin and vimentin were determined in Zavot cattle skin using standard immunohistochemical techniques. Skin samples were collected from the different regions of the bodies. Vimentin-immunoreactivity was observed in the cells of subepidermal region, in the myoepithelial cells surrounding sebaceous and sweat glands, in the fibroblast, smooth muscle, endothelial cells of vessels and some hair follicles. Desmin-immunoreactivity was dense in the smooth muscle of arrectores pilorum muscles and bulbus pilorum of the some hair follicles. Desmin and vimentin immunoreactivities were not different among the various regions of Zavot cattle skin.

The Possibilities Of Twice-Yearly Lambing Of Awassi Sheep Ewes Without Using Hormones In An Organic Animal Production System, Ümi̇t Yavuzer
Turkish Journal of Veterinary & Animal Sciences
This goal of the present research was to determine the possibility of twice-yearly lambing in Awassi sheep. The research was appropriate in terms of ecological agriculture, animal breeding applications, and organic agricultural production with no impact on their health or behavior, or exposure to environmental conditions such as exogenous hormone applications. The research was carried out after the February 2001 lambing season. Rams were introduced to the ewe flock while the lambs were weaning. The sheep's giving birth in August 2001 indicated that they had become pregnant while the lambs were weaning. The fertility rate in the August 2001 birth …

Turkish Journal of Veterinary & Animal Sciences
The sero-prevalence of contagious ecthyma (orf) in lambs and humans was studied in the Kars region of Turkey. For this purpose, serum samples were collected from 320 lambs from 5 different districts of the Kars region. Serum samples were also collected from 100 humans at risk of infection. The serum samples were tested for the presence of antibodies to orf virus by enzyme-linked immunosorbent assay (ELISA). The results showed that 52.81% and 5% of the serum samples collected from lambs and humans, respectively, were seropositive for orf virus. These results indicate that contagious ecthyma is a prevalent infection in lambs …

Turkish Journal of Veterinary & Animal Sciences
In the present study cloning of the NP gene in a cloning vector is reported. For this purpose, Vero cells were infected with rinderpest RBOK vaccine strain. Total RNA was obtained from the infected cells and reverse-transcription (RT) was performed to get cDNAs of NP gene. Afterwards, the NP gene was amplified by polymerase chain reaction (PCR) with the primers specific to the NP gene. The NP gene, 1575 bp in length, was cloned into pGEM-3Zf (-) cloning vector. PCR screening and enzyme digestion assays carried out to verify the presence of the NP gene.

Turkish Journal of Veterinary & Animal Sciences
In this study, some external and internal quality characteristics of pheasant (Phasianus colchicus) eggs with white, blue, brown, or olive green shells were investigated. A total of 120 pheasant eggs including 9 white, 4 blue, 24 brown and 83 olive green eggs (collected in the same laying period and randomly) were used in this study. The values of egg weight, shape index, eggshell weight and shell membrane weight of the brown and the olive green eggs were found different from those of the blue and white color eggs (P < 0.05). Yolk and albumen weights of the white, blue, brown, and olive green eggs were found 9.03 and 16.28 g, 9.57 and 14.37 g, 10.72 and 17.96 g, 10.13 and 17.79 g, respectively (P < 0.05). The effect of eggshell colors on the yolk index, albumen index, shell thickness, membrane thickness, and Haugh Unit was found to be insignificant (P < 0.05). As a result of this study, the quality of brown and olive green eggs were better than blue and white eggs.

Turkish Journal of Veterinary & Animal Sciences
The aim of the present study was to determine median lethal concentrations (LC 50) of unionised ammonia (NH_{3}) for the larvae and fingerlings of Tilapia (Oreochromis niloticus L. 1758). The mean 48 h LC50 values were determined as 1.009 ± 0.02 mg/l for larvae and 7.40 ± 0.01 mg/l for the fingerlings. Larvae exposed to different concentrations of ammonia moved very rapidly, lost equilibrium in water and showed sideways swimming. In the case of the fingerlings, an increase in their movements, ventilation, convulsions, spiral swimming, efforts to swallow air from the surface of water, increase in the mucous secretion in …

The Effects Of Formic Acid, Molasses And Inoculant As Silage Additives On Corn Silage Composition And Ruminal Fermentation Characteristics In Sheep, Erol Baytok, Taylan Aksu, M. Aki̇f Karsli, Habi̇p Muruz
Turkish Journal of Veterinary & Animal Sciences
The objective of this study was to determine the effects of formic acid, molasses, and microbial inoculant (homofermentative lactic acid bacteria) as silage additives on silage quality and ruminal fermentation characteristics. Silages with or without formic acid (0.5%), molasses (5%), or microbial inoculant (10 g/t) were fed to ruminally cannulated, 1.5 year-old Kıvırcık x Morkaraman sheep. Silage treated with molasses had significantly greater DM and CP concentrations compared with other groups (P < 0.05). pH values did not significantly differ among treatments (P > 0.05). Lactic acid concentrations were significantly higher in silages treated with enzyme or molasses compared with others (P < 0.05). While acetic acid concentration was the highest in silage treated with acid, it was the lowest in silage treated with molasses (P < 0.05). Silage NH_{3}-N concentration was the highest in silage treated with molasses, but the lowest in silage treated with acid (P < 0.05). Post-feeding ruminal total organic acid concentrations were significantly greater in sheep fed silages with additive than the control (P < 0.05). While percentages of acetic acid were greater, percentages of butyric acids were less in the rumen fluid of sheep fed silage without additive compared with the rumen fluid of sheep fed silage treated with silage additives. However, percentages of propionic acid did not differ among treatments.

Turkish Journal of Veterinary & Animal Sciences
A series of experiments were conducted to determine the effects of rainbow trout serum (RTS), taken from rainbow trout (Oncorhynchus mykiss) that have never experienced infectious pancreatic necrosis disease, on infectious pancreatic necrosis virus (IPNV) in vitro and in vivo. In vitro, 109 IPNV isolates belonging to various subtypes and having various degrees of virulence were passed in the presence and absence of 1% RTS on rainbow trout gonad (RTG-2) cell line. Moreover, brook trout (Salvelinus fontinalis) were challenged with four virulent Buhl subtype isolates passed 11 times in the presence and absence of 1% RTS. Avirulent isolates of IPNV …
