Purified basolateral membrane vesicles were prepared from the intestinal epithelium of the tilapia Oreochromis mossambicus, a herbivorous teleost. Characteristics of volatile fatty acid (VFA) transport were investigated using [H]acetate as a representative anion. No significant change in [H]acetate influx was observed in the presence of a cation gradient (K or Na) compared to the influx observe...

STEVENS, C. E., AND B. K. STETTLER. Factors affecting the transport of volatile fatty acids across rumen epithelium. Am. J. Physiol. 2 IO(~) : 365-372. I g66.-Isolated, short-circuited rumen epithelium was used to study the effects of pH, concentration gradient, imidazole vs. bicarbonate-buffer systems, and fatty acid metabolism on the transport of volatile fa tty acid. Transport of acetate a n...

Fourteen primiparous Holstein cows (180.0 ± 4.3 days in milk) with a mean (±SD) daily milk yield of 35.0 ± 1.3 kg and a body condition score of 3.2 ± 0.2 were allotted into two groups (n = 7), and were fed a ration consisting of (dry matter basis) 35% corn silage, 25% alfalfa hay and 40% concentrates. Salt was provided free choice. The experiment was performed during the period of heat stress, ...

The odd- and branched-chain fatty acids (OBCFA) accumulated in ruminant products are a class of beneficial for human health. Since biotin leucine involved OBCFA synthesis, this study aimed to evaluate their effect on synthesis vitro. There were four treatments: the control group that only provided basal diet, or diet supplemented with (4 mg/kg dry matter, DM), g/kg combination DM) DM). results ...

Many studies show concentrations of nutritionally desirable fatty acids in bovine milk are lower when cows have no access to grazing, leading to seasonal fluctuations in milk quality if cows are housed for part of the year. This study investigated the potential to improve the fatty acid profiles of bovine milk by oilseed supplementation (rolled linseed and rapeseed) during a period of indoor fe...

Larson, A. D. (Louisiana State University, Baton Rouge), L. V. Hattier, and C. S. McCleskey. Volatile fatty acid requirement of a strain of Listeria monocytogenes. J. Bacteriol. 89:819-824. 1965.-Listeria monocytogenes strain 2 requires either isobutyric or 2-methylbutyric acid for growth. Elucidation of this requirement began with characterization of the growth-enhancing substance in culture f...

objective: the effects of dietary fish oil on semen quality and sperm fatty acid profiles during consumption of n-3 fatty acids as well as the persistency of fatty acids in ram’s sperm after removing dietary oil from the diet were investigated. materials and methods: in this experimental study, we randomly assigned 9 zandi rams to two groups (isoenergetic and isonitrogenous diets): control (ctr...

for determining the fatty acid characteristics and biodiesel quality of ethiopian jatropha provenances, the study was conducted in five regions namely southern nation nationalities peoples regional state (snnprs), amhara region, tigria region, oromia region and benishangul gumuz regions, where physic nut is found abundantly. for each region, representative sampling sites were selected following...

b a ckground:  scientific literature has shown evidence that omega-3 polyunsaturated  fatty  acids  (pufa)  have  anti-androgenic  action,  and  for  this reason could be useful as an adjuvant in hyperandrogenism conditions including polycystic ovarian syndrome (pcos). however, the possible effect of eicosapentaenoic acid (epa) and docosahexaenoic acid (dha) supplementation on testosterone conc...
