The diagnosis of ruminant theileriosis in Turkey is based on microscopical examination of thin blood and lymph smears, serology, traditional staining methods of the salivary glands of ticks and molecular techniques. Although some investigators reported that T. mutans was found in cattle with microscopic examination (7.4%-36.7%) and experimental study, they did not detect this parasite using mol...
In this issue of the Journal, 2 groups of investigators report carefully conducted controlled feeding studies in healthy volunteers that compared the effects on blood lipids of trans fatty acids (TFA) from industrial (partially hydrogenated vegetable oil) and from dairy (ruminant or “natural”) sources. Chardigny et al (1) compared industrially derived and ruminant-derived TFA at 5% of energy. M...
b a ckground: the present study aimed to demonstrate the seasonal activities of ixodes ricinus at the pasture level and on the host. m e t hods: a vast pasture in amol countryside (mazandaran province, iran) which had the potential for a considera- ble number of cattle and sheep to graze was chosen. tick sampling from the skin of 130 cattle and 130 sheep were collected every month interval. sim...
Beauchemin and Rode (1996) recently reviewed the use of enzymes in ruminant diets, however, enzymes in the form of crude whole fungal cell preparations have been used to enhance ruminant production for many years. This paper aims to investigate the similarities between the emerging feed enzymes and fungal feed additives, and to use this information to speculate on potential modes of action of d...
There is increasing evidence to indicate that nutrition is an important factor involved in the onset and development of several chronic human diseases including cancer, cardiovascular disease (CVD), type II diabetes and obesity. Clinical studies implicate excessive consumption of medium-chain saturated fatty acids (SFA) and trans-fatty acids (TFA) as risk factors for CVD, and in the aetiology o...
The gastrointestinal (GI) habitat of ruminant and non-ruminant animals sustains a vast ensemble of microbes that are capable of utilizing lignocellulosic plant biomass. In this study, an indigenous swine (Zovawk) and a domesticated goat (Black Bengal) were investigated to isolate bacteria having plant biomass degrading enzymes. After screening and enzymatic quantification of eighty-one obtained...
The objective of this work was to evaluate hematological, biochemical and ruminant parameters for diagnosis and treatment of the left displaced abomasum (LDA) in dairy cows, in the Plateau Region of Rio Grande do Sul, Brazil. Ruminant fluid, blood and urine samples were collected from 20 cows suffering LDA and from 20 healthy cows (control). The cows with LDA showed lower values of daily milk p...
1. A method for gas-liquid chromatographic analysis of the dimethyl esters of a homologous series of diabolic acids is described. 2. Only when combined with low-resolution mass spectrometry could the method be used to show unequivocally the existence of diabolic acids in natural products. 3. Diabolic acids occurred naturally in rumen and faecal lipids of all ruminants examined but could not be ...
Advances in our understanding of lipid metabolism in the ruminant and the effect of specific fatty acids on both ruminant metabolism and human health has increased significantly in recent years. Unique biohydrogenation intermediates formed in the rumen have been shown to be potent inhibitors of milk fat synthesis, and the biology behind this and its potential application and benefit to both ani...
