This experiment was conducted to investigate the effect of lemongrass [Cymbopogon citratus (DC.) Stapf.] powder (LGP) on rumen ecology, rumen microorganisms, and digestibility of nutrients. Four ruminally fistulated crossbred (Brahman native) beef cattle were randomly assigned according to a 4 x 4 Latin square design. The dietary treatments were LGP(More)
A real-time polymerase chain reaction approach was used in this study to determine the population of major ruminal bacterial species (Fibrobacter succinogenes, Ruminococcus albus, and Ruminococcus flavefaciens) in digesta and rumen fluid of swamp buffalo (Bubalus bubalis). Four rumen-fistulated, male swamp buffalo were randomly assigned according to a 4 x 4(More)
Four crossbreds (75% Holstein Friesian) lactating dairy cows were used to evaluate the effects of sunflower oil (SFO) levels and roughage source on feed intake, nutrient digestibility, ruminal fermentation, milk yield, and milk composition. Four milking cows with average liveweight of 410 ± 25 kg and 18 ± 11 days in milk were randomly assigned according to(More)
Four fistulated Holstein Friesian heifers were used in a 4 × 4 Latin square design with a 2 × 2 factorial arrangement. The main factors were two roughage-to-concentrate ratios (R:C, 70:30 and 30:70) and two supplementation levels of soapberry fruit-mangosteen peel (SM) pellets (0 and 4% tannins-saponins of total diets). Rice straw was used as a roughage(More)
The objective of this study was to investigate the effects of tannins and saponins in Samanea saman on rumen fermentation, milk yield and milk composition in lactating dairy cows. Four multiparous early-lactating dairy cows (Holstein-Friesian cross-bred, 75%) with an initial body weight (BW) of 405 ± 40 kg and 36 ± 8 day in milk were randomly assigned to(More)
The objective of this study was to determine the effect of rain tree pod meal with palm oil supplementation on feed intake, digestibility, microbial protein synthesis and microbial populations in dairy cows. Four, multiparous early-lactation Holstein-Friesian crossbred (75%) lactating dairy cows with an initial body weight (BW) of 405±40 kg and 36±8 DIM(More)
Four rumen fistulated swamp buffaloes were randomly assigned according to a 4×4 Latin square design to investigate the effects of Eucalyptus (E. Camaldulensis) leaf meal (ELM) supplementation as a rumen enhancer on feed intake and rumen fermentation characteristics. The dietary treatments were as follows: T1 = 0 g ELM/hd/d; T2 = 40 g ELM/hd/d; T3 = 80 g(More)
Four, ruminally fistulated crossbred (Brahman×native) beef cattle with initial body weight of 420±15 kg were randomly assigned according to a 4×4 Latin square design. The dietary treatments were mulberry leaf pellet (MUP) supplementation at 0, 200, 400 and 600 g/hd/d with rice straw fed to allow ad libitum intake. All steers were kept in individual pens and(More)
In this experiment the effects of different urea products (urea [U] and urea-calcium mixtures [UCM]) on rumen fermentation were investigated in dependence of different energy sources by using in vitro techniques. The 7 x 2 factorial arrangement followed a completely randomised design using seven urea products (U100, U40CaCl2, U50CaCl2, U60CaCl2, U40CaSO4,(More)
A number of experiments have been conducted to investigate effects of tropical plants containing condensed tannins and/or saponins present in tropical plants and some plant oils on rumen fermentation and ecology in ruminants. Based on both in vitro and in vivo trials, the results revealed important effects on rumen microorganisms and fermentation including(More)
