Received: Revised: Accepted: September 18, 2014 September 27, 2014 October 15, 2014 In this study, the effect of fermentative disorders such as acid and alkaline indigestion was investigated in buffaloes. Six buffaloes each suffering from acid and alkaline indigestion was chosen and various physiological parameters were compared with six healthy buffaloes Clinical examination was carried out to...

This study aimed to investigate the impact of repeated acidosis challenges (ACs) and the effect of live yeast supplementation (Saccharomyces cerevisiae I-1077, SC) on rumen fermentation, microbial ecosystem and inflammatory response. The experimental design involved two groups (SC, n=6; Control, n=6) of rumen fistulated wethers that were successively exposed to three ACs of 5 days each, precede...

introduction ensiling is less dependent to weather condition and farmers are trying to ensile forages for preserving them for livestock feeding. ensiling legumes because of their buffering capacity and high moisture content are difficult. also, ensiling alfalfa will lose up to %85 of its nitrogen content as non-protein nitrogen. adding some additives like carbohydrate sources will improve alfal...

Abstract The present study aimed to evaluate the effects of ruminal fluid pH on fatty acids (FA) profile bovine milk. experiment was performed 250 Polish Holstein-Friesian cows reared in 11 commercial high-yielding dairy farms. Ruminal samples were collected by rumenocentesis, and fat FA concentrations milk analyzed Fourier transform infrared spectroscopy. According pH, categorized into three g...

The targeting of mcrA or 16S rRNA genes by quantitative PCR (qPCR) has become the dominant method for quantifying methanogens in rumen. There are considerable discrepancies between estimates based on different primer sets, and the literature is equivocal about the relationship with methane production. There are a number of problems with qPCR, including low primer specificity, multiple copies of...

The development of the rumen digestive functions was studied in lambs placed in sterile isolators at 1, 4, 8 or 9 days of age to define the role of the bacterial species that colonize the rumen just after birth. The values of the main rumen digestive parameters (pH, concentrations of volatile fatty acid, ammonia, lactic acid) in these lambs were close to those observed in conventional controls....

This research was conducted to estimate the amount of microbial protein synthesis in Iranian buffaloes' rumen. Four male swamp buffaloes with average live body weight of 140±10 kg were used in this study. Four diets of 0 (control diet, 100% forage), 15, 30 and 45% concentrate in a 4 × 4 Latin Square were tested. The results indicated that by increasing the concentrate level in the diet of swamp...

I. 15NH4C1 was continuously infused for periods of 120-216 h into the rumens of sheep which were allowed to feed 2 out of every 10 min. These treatments achieved steady metabolic states and allowed the assessment of nitrogen conversions by means of tracer methodology. The sheep were given either a barley diet or one of three hay diets. In two trials, the flow of abomasal material was determined...

BACKGROUND: Manipulation of rumen microbial population for improving animal performance is done by several methods including medicinal plants. Matricaria chamomille (chamomile) and Cichorium intybus (chicory) are two medicinal plant with antibacterial effect that there is little information about the effects of them on rumen microflora. OBJECTIVE: The present study was carried out to evaluate t...
