Seasonal Variation Of Vitamin A And Beta-Carotene Levels In Ghezel Sheep, Gholamreza Afshari, A. Hasanpour, H. Haghpanah, Bahram Amoughli-Tabrizi

Turkish Journal of Veterinary & Animal Sciences

The present study was conducted to investigate the variations in blood serum and hepatic levels of vitamin A and b-carotene in Ghezel sheep throughout the year. From 1000 sheep aged 1-5 years, blood and liver samples were collected before and after slaughter. The levels of vitamin A and \beta-carotene in both samples were determined spectrophotometrically. The results showed significant differences between summer and winter values (P < 0.05), but no differences were found between the sexes (P > 0.05). There were significant correlations between the vitamin A levels in serum and the liver (P < 0.05). Due to low levels of vitamin A and \beta -carotene in Ghezel sheep during the winter, supplementary feeding of vitamin A is recommended during this season.

Apparent Nutrient Digestibility Of Balanced Diets With Soy Bean Extract Or Meat And Bone Meal In The Nile Tilapia (Oreochromis Niloticus L.) Infected With Vibrio Anguillarum, Kenan Engi̇n, Ferbal Özkan Jan 2008

Apparent Nutrient Digestibility Of Balanced Diets With Soy Bean Extract Or Meat And Bone Meal In The Nile Tilapia (Oreochromis Niloticus L.) Infected With Vibrio Anguillarum, Kenan Engi̇n, Ferbal Özkan

Turkish Journal of Veterinary & Animal Sciences

Nile tilapia, Oreochromis niloticus L., infected with Vibrio anguillarum or not infected were fed balanced diets containing vegetal (solvent extracted soy bean meal (SBM)) or animal (meat and bone meal (MBM)) protein sources in order to demonstrate the apparent nutrient and energy digestibility. Regardless of protein sources in the diets, feed intake was lower in the infected group. Apparent nutrient (AD_{DM} and AD_{CP}) and energy digestibility (AD_{kJ}) values of Nile tilapia fed the SBM diet were significantly better (P < 0.05) than those fed the CONT and MBM diets and changed little between the measurement days in both groups (non-infected and infected). Although no visible symptoms associated with vibriosis were evident on either the skin or internal organs, the significantly lower (P < 0.05) AD_{DM}, AD_{CP}, and AD_{kJ} values obtained between day 1 and 10 (specifically on days 3 and 10) in the infected group fed the CONT and MBM diets might have implicated the pathogenicity of the bacteria. Further research concentrating on higher amounts of solvent extracted soy bean and meat and bone meal, different environmental conditions and doses of infection with V. anguillarum and immune response parameters including physiological and cellular stress responses is needed in order to identify the overall apparent nutrient digestibility of plant and animal protein sources in Nile tilapia infected with V. anguillarum.

Hypocalcaemia In Ossimi Sheep Associated With Feeding On Beet Tops (Beta Vulgaris), Sabry El-Khodery, Mohamed El-Boshy, Khalid Gaafar, Abdelbaset Elmashad Jan 2008

Hypocalcaemia In Ossimi Sheep Associated With Feeding On Beet Tops (Beta Vulgaris), Sabry El-Khodery, Mohamed El-Boshy, Khalid Gaafar, Abdelbaset Elmashad

Turkish Journal of Veterinary & Animal Sciences

Hypocalcemia was diagnosed in 48 Ossimi ewes in a flock of 125 sheep. Clinical signs, feed analysis, biochemical findings, and response to treatment were used for diagnosis. Lactating ewes were more frequently affected (56.25%) than pregnant (33.33%) and dry non-pregnant (10.41%) ewes. Teeth grinding, voiding soft pellets, absence of recumbency, non-tympanic rumen, dry mouth, and thin body condition were atypical findings. Ruminal fluid analysis showed significant increases of potassium and ammonia (P < 0.05), and a significant decrease of magnesium (P < 0.05) in diseased ewes, as compared with clinically normal ewes. Serum calcium, magnesium, and glucose in the diseased ewes were significantly lower (P < 0.001), (P < 0.01), (P < 0.05) than in clinically normal and control ewes, respectively; however, there was a significant increase of acetone (P < 0.01). In all, 2 ewes were slaughtered due to the failure to respond to treatment and only the kidneys had gross abnormality. Histopathological examination showed degenerative changes in the renal tubules, with deposition of calcium oxalate crystals. The results of this study indicate that the clinical syndrome of hypocalcemia and renal failure occurred in Ossimi sheep that feed on beet tops. The observed atypical signs of hypocalcemia highlight the importance of examining serum and ruminal fluid to determine the proper intervention.

Anticoagulant Rodenticide Intoxication In Animals – A Review, Ivan Valchev, Rumen Binev, Veska Yordanova, Yordan Nikolov Jan 2008

Anticoagulant Rodenticide Intoxication In Animals – A Review, Ivan Valchev, Rumen Binev, Veska Yordanova, Yordan Nikolov

Turkish Journal of Veterinary & Animal Sciences

The newest measures for the control of harmful rodent populations are from the anticoagulant rodenticide group, which are divided into 2 subgroups: first and second generations, and indandione derivatives. Non-target organisms are potentially at risk of direct consumption of baits (primary hazard) and of eating poisoned rodents (secondary hazard). Anticoagulant rodenticides inhibit the enzyme vitamin K-dependent carboxylase and thus impair the reactivation of vitamin K1, indirectly affecting physiological blood coagulation. The diagnosis is made on the basis of clinical signs (massive hemorrhages), laboratory findings, and especially the changes in coagulation markers (APTT, PT, TT, PCT, ACT, FDPs, and PIVKA). The …

Effects Of Age, Sex, Feather Colour, Body Measurements, And Body Weight On Down And Feather Yield In Native Turkish Geese, Mustafa Saatci

Turkish Journal of Veterinary & Animal Sciences

The aim of this study was to calculate the feather and down production by native Turkish geese and to investigate the effects on these traits. In total 145 native Turkish geese were used in the experiment. The birds were divided into 4 groups according to their feather colour at 10 and 12 weeks of ages. They were individually weighed and measured with the help of wing tags. Geese at 10 weeks had heavier feathers than those at 12 weeks, while geese at 12 weeks produced more down (P < 0.01). As detected in down weight, the older group has a greater amount of total feathers than the younger group (P < 0.001). Male geese produced significantly heavier feathers and down than females (P < 0.05). While black geese produced the heaviest feathers, yellow geese produced the heaviest down (P < 0.05). White geese generated the lightest weights of the products. The strongest correlation was found between total feather yield and chest girth (0.75). Reasonable correlations were detected between liveweight and other traits (0.36-0.62). This is not a widely studied subject in Turkey; therefore, the data obtained can be used for the identification of native Turkish geese.

Alleles of physiological candidate genes for reproductive traits, insulin-like growth factor-1 (IGF-1), and growth hormone receptor (GHR) were assessed to determine their associations with total egg production (NE), average days of continual egg-laying (ADCE), and number of double yolk eggs (DYE) in Wenchang chickens (Chinese indigenous breed). PCR-RFLP was used for genotype identification. The frequency of restriction enzyme C1/C2 alleles in the population was 0.53 (C1) and 0.47 (C2) for IGF-1. For GHR-intron 2 it was 0.06 and 0.94 for (A1) and (A2), respectively, while for GHR-intron 5 it was 0.20 (B1) and 0.80 (B2). Four significant associations were found …
