Turkish Journal of Veterinary & Animal Sciences

This research paper is aimed at estimating foot-and-mouth disease (FMD)-induced production losses in individual dairy and fattening cattle in Turkey. The data used were obtained from a Delphi Expert Opinion Survey. The weighted average FMD-induced financial losses for all breeds were estimated to be $294/head for a milking cow, $152/head for a dairy heifer and $197/head for beef cattle. However, the amount of financial loss varied across different breeds, ages, and sexes. The study findings suggest that culling Holstein breed cows, beef cattle, and Holstein and cross breed female calves, as soon as they have an FMD infection, would be …

Turkish Journal of Veterinary & Animal Sciences

Seventeen Eastern Anatolian Red (EAR) bulls at 20 months of age were divided into 2 treatment groups and fed for either 168 days (S) or 210 days (L). Initial and final weights were not significantly different. While bulls in the L group had the highest total weight gain (149.0 vs. 177.2 kg), feed efficiency ratio was superior for the cattle fed for 168 days. Carcass weight, spleen and front + hind feet weights as a percentage of slaughter weight, weight of kidney fat, percentage of kidney, pelvic, and heart fat, and yield grade all increased (P < 0.05) with feeding time. Bulls in the L group received a higher (P < 0.05) panel rating for juiciness, and the panel juiciness score was closely associated with tenderness measurements such as panel tenderness score, Warner Bratzler shear force value, and number of chews before swallowing. It is concluded that duration of finishing significantly influenced carcass, slaughter, and organoleptic beef quality traits of young EAR bulls.

Immunomodulatory And Protective Effects Of Sugar Cane Juice In Chickens Against Eimeria Infection, Masood Akhtar, M. Abdul Hafeez, Faqir Muhammad, Ahsan Ul Haq, M. Irfan Anwar

Turkish Journal of Veterinary & Animal Sciences

Present paper reports the effects of sugar cane juice (SCJ) on immune responses and its protection against Eimeria (mixed species) infections in broiler chickens. Experiment 1 was conducted to test the dose efficacy of SCJ and its effects on chickens against coccidiosis. Maximum weight gain per day was recorded in chickens given SCJ @ 400 mg/kg body weight. Significantly (P < 0.01) low mortality and increased body weight gain per day were recorded in chickens administered SCJ orally and challenged with mixed species of genus Eimeria. Furthermore, mild hemorrhages, lower lesion scores (+1), and significantly lower number of oocysts shed in faeces were recorded in immunized chickens compared to control. Experiment 2 was carried out to evaluate the immunomodulatory effects of SCJ on cellular and humoral responses. Highest antibody titres (1:1024-1:16; GMT 367.28) were recorded in chickens administered SCJ @ 400 mg/kg body weight in comparison with control (1:16-1:2; GMT 2.82). To demonstrate the cell mediated immunity (CMI), amplitude of toe-web swelling 72 h post avian tuberculin injection was recorded in the experimental and control groups. Maximum swelling (8.13 ± 0.21 mm) was recorded in the experimental group as compared to control (1.04 ± 0.10); indicating higher cell mediated immune response. From these results it was concluded that SCJ elicit a significantly higher cellular and humoral responses compared to control, which may provide protection against Eimeria infections (mixed species) in chickens.

Turkish Journal of Veterinary & Animal Sciences

This study aimed to determine the shelf life, as well as chemical and microbiological quality of gilthead seabream (Sparus aurata L., 1758) prepared by 2 different methods of smoking (hot smoking and cold smoking). The effects of hot and cold smoking on the chemical composition and microbial load of gilthead seabream, as well as organoleptic analysis of the smoked product were investigated. Significant (P < 0.05) differences were found in the chemical composition of fresh and smoked seabream. The panelists liked the hot smoked fish more than the cold smoked fish, according to sensory analysis results. Changes in pH, thiobarbituric acid (TBA), and total volatile basic nitrogen (TVB-N) values were significant (P < 0.05) during storage at 4 °C. Microbiological analysis results demonstrated that the smoking techniques reduced the microbial content of the fish, whereas microbial content increased during storage. The smoking methods tested had a small effect on the level of vitamin D_3 in gilthead seabream.

Influence Of Additives And Fermentation Periods On Silage Characteristics, Chemical Composition, And In Situ Digestion Kinetics Of Jambo Silage And Its Fodder In Nili Buffalo Bulls, M. Aasif Shahzad, Muhammad Sarwar, Mahr-Un Nisa, N. A. Tauqir

Turkish Journal of Veterinary & Animal Sciences

Jambo grass (Sorghum bicolour x Sorghum sudanefe) harvested 50 days after sowing was ensiled in laboratory silos using 2 additives, cane molasses and ground corn grains, each at the rate of 2%, 4%, and 6% levels for 30, 35, and 40 days at room temperature (28 °C). Data regarding incubation days were pooled. The pH and lactic acid concentration in jambo grass silage were not affected by the additive type, level, or fermentation period. Dry matter (DM) content of jambo silage was significantly (P < 0.05) affected by additive type; however, additive levels and fermentation periods did not affect its DM contents. Crude protein content of jambo grass was not affected by ensiling time, additive type, or level. The true protein contents of jambo grass silage were significantly (P < 0.05) higher with molasses than with ground corn. Neutral detergent fiber (NDF) and hemicellulose content of jambo grass were significantly (P < 0.05) affected by additives and their levels, but fermentation periods did not influence the NDF contents of jambo grass silage. Cellulose, acid detergent fiber, and acid detergent lignin contents of jambo silage were not affected by additive type, level, or fermentation period. Therefore, jambo grass ensiled with 2% molasses for 30 days was selected for in situ digestion kinetics in bulls. Dry matter and NDF degradabilities of jambo grass were significantly higher than those of its silage at 48 h of ruminal incubation. Ruminal lag time, and rate and extent of DM and NDF degradation were similar for jambo grass and its silage. The results of this study implied that jambo grass ensiled with 2% molasses for 30 days has similar nutritive value to that of its forage in bulls.

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.

Managing Bovine Tuberculosis In White-Tailed Deer In Northwestern Minnesota: A 2008 Progress Report, Michelle Carstensen, Erika Butler, Michael Doncarlos, Lou Cornicelli

Michigan Bovine Tuberculosis Bibliography and Database

Bovine tuberculosis (TB), first discovered in 2005, has now been found in 12 cattle operations in northwestern Minnesota. To date, all of the infected cattle herds have been depopulated and the Board of Animal Health (BAH) has continued to test cattle herds in the area. The strain has been identified as one that is consistent with Bovine TB found in cattle in the southwestern United States and Mexico. In response to the disease being detected in cattle, the Minnesota Department of Natural Resources (MNDNR) began surveillance efforts in free-ranging white-tailed deer (Odocoileus virginianus) within a 15-mile radius of …
