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...

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...

1. The effects of four diets on water intake, rumen fluid outflow-rate, rumen pH and mineral metabolism were studied in wether sheep. The diets were barley and hay, flaked maize and hay, dried grass and frozen grass. 2. Experimental periods were of 12 d duration, and plasma magnesium concentrations were lower at the end of treatment periods when the grass diets were given and were significantly...

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...

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....

Organic fertilizer raw materials that can be obtained naturally and are rich in nutrients found animal slaughtering activities. Slaughtering activities generally produce waste manure, which used as material for organic fertilizer. This study aimed to investigate the effect of composition on quality fertilizers. The parameters studied were C/N, P, K, pH, temperature. four reactors with each reac...

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...

This study examined the reticulo-rumen characteristics of the microbial community and its fermentative characteristics in milk-fed, at weaning and finished lambs in a conventional fattening system. Five lambs were assigned to each of three groups: milk-fed lambs slaughtered at 30 days (T30), weaned lambs slaughtered at 45 days (T45) and 'finished lambs' slaughtered at 90 days (T90). At slaughte...
