Toxoplasma gondii DNA was detected at rates of 2%, 6%, 4.17%, 20%, and 19% in 50 bovine brains, 50 bovine muscles, 120 ovine brains, 20 ovine muscles, and in 100 fermented sausage samples, respectively. Sequenced positive samples showed 100% identity with T. gondii RH strain. Seropositivity rates were detected as 24% in cattle and 25% in sheep slaughtered in local slaughterhouses. The detection...

Genetic markers in casein (CSN1S1) and thyroglobulin (TG) genes have previously been associated with fat distribution in cattle. Determining the nature of these genetic associations (additive, recessive, or dominant) has been difficult, because both markers have small minor allele frequencies in most beef cattle populations. This results in few animals homozygous for the minor alleles. selectio...

Lee, H. J . , P . D. Ryu, H. Lee, M. H. Cho, M. H. Lee:Screening for Penicillin Plasma Residues in Cattle by Enzyme-Linked Immunosorbent Assay. Acta Vet. Brno 2001, 70: 353–358. In this study, we established a rapid prediction test for the detection of the cattle with violative tissue residues of penicillins. The recommended therapeutic doses of two penicillins, ampicillin (withdrawal time, 6 d...

The aim of this study was to investigate the role of livestock cooperatives in improving economic status of animal holders in Hamedan province. The study has used a surveying methodology. For gathering data a structured questionnaire was used and its reliability was calculated by Cronbach's Alpha test and it was (α=0.80). The research samples consisted of 300 animal holders (beef cattle breeder...

Tenderness is the single most important factor influencing consumer acceptance of meat. The calpain proteolytic system is known to be responsible for the post-mortem tenderization of meat. The purpose of this study was to determine and compare the tensile strength and total calpain activities in different muscles of camel, cattle, sheep and goat. In camels, the effect of age and sex of animal w...

Murrah buffalo and Nellore cattle meat commercialized in Southeastern Brazil were evaluated during aging. Ribeye steaks (Longissimus thoracis muscle) analyzed four wet aging times (0, 7, 14, 21 days) stored at 2 ± 1 °C. The water holding capacity (WHC) decreased (p < 0.05) (0.41 to 0.28), with having lower pH a higher WHC than beef. Lower myofibrillar fragmentation index shear force (WBsSF) ...

Introduction: There are three synthetic hormones approved by the U.S. Food and Drug Administration (U.S. FDA) for growth promotion in cattle and sheep raised for meat production: the estrogenic compound zeranol, the anabolic steroid trenbolone acetate (TBA), and the progestin melengestrol acetate (MGA). The FDA approves and regulates the use of hormone implants, establishing tolerance levels (m...

The seroprevalence of Toxoplasma gondii was examined in adult women and domestic animals used for meat products from the Mymensingh District, Bangladesh. Cattle, goats and sheep showed a high seroprevalence (12, 32 and 40%, respectively), while the sera from all fifteen women examined in the same area were seronegative. Considering that primary infection in women during pregnancy can cause abor...

Between 1988 and 1993 the International Union of Nutritional Sciences Committee 'Nutrition and Ageing' established the international 'Food Habits in Later Life' (FHILL) Program.1,2 The FHILL program documented current and distant past food habits of more than 2000 Caucasian and Asian elderly people, which also included 54 older Aboriginal Australians in a community called Junjuwa in the Fitzroy...

Beef derived from Holstein steers is a significant source of the U.S. beef supply. The nation’s 9.1 million dairy cows in 2003 were 22% of the U.S. cow herd (NASS, 2005). Given the typical breed distribution of dairy cows, calving interval, full-term pregnancy rate, peri-natal calf death loss (NAHMS, 2002), gender distribution, dairy beef placement (80%) and survival to market (94%), it can be ...
