The objective of this study was to investigate the effect of banana flower powder (BAFLOP) supplementation on gas production kinetics and rumen fermentation efficiency in in vitro incubation with different ratios of roughage to concentrate in swamp buffalo and cattle rumen fluid. Two male, rumen fistulated dairy steers and swamp buffaloes were used as rumen fluid donors. The treatments were arr...

The feed and feces of a continuously fed sheep were analyzed for carbon, hydrogen, and nitrogen, with oxygen as the remainder. The daily feed-feces weight difference was used as the reactant in an equation representing the rumen fermentation. The measured products were the daily production of volatile fatty acids (VFA), CH4, CO2, and ammonia. The carbon unaccounted for was assumed to be in the ...

The loss of energy which occurs in the rumen fermentation can be very appreciable (Czerkawski, 1969) and it is therefore not surprising that efforts are being made to find ways of manipulating the fermentation to minimise this loss. The area has been reviewed by Marty, (1972), Demeyer and Van Nevel (1975) and Czerkawski (1969). In addition to the energy consideration a number of conditions exis...

In vitro fermentation experiments and a feeding trial were conducted to determine how distillers byproducts impact rumen microbiology and metabolism. The in vitro rate of lactic acid disappearance was not stimulated by direct addition of distillers byproducts to mixed rumen contents collected from a steer adapted to a high concentrate diet. However, if animals were fed condensed distillers bypr...

S TUDIES by Appleby et al. (1956), Gutierrez and tlungate (1957), Eadie et al. (1959) and Eadie and Hollson (1962) indicated that ciliate protozoa normally inhabiting the rumen exerted considerable influence upon end products of rumen fermentation and upon tureen bacterial populations. The full significance of protozoa to the nutrition of cattle and sheep is not clear. However, Christiansen et ...

The present study aimed at investigating the effects of essential oils and their bioactive compounds (EOBC) on rumen fermentation in vivo as well as animal performance and feed efficiency in different ruminant species, using a meta-analysis approach. Ruminant species were classified into 3 classes consisting of beef cattle, dairy cattle, and small ruminants. Two datasets (i.e., rumen fermentati...

The aim of the current study was to explore the use of the tracer C as an internal marker to assess feed fraction-specific digesta passage kinetics through the digestive tract of dairy cows. Knowledge on feed-specific fractional passage rates is essential to improve estimations on the extent of rumen degradation and microbial protein efficiency; however, this information is largely lacking. An ...

The use of Tasco (air-dried Ascophyllum nodosum) as a feed supplement for ruminants has been reported to affect rumen fermentation and reduce Escherichia coli O157:H7 shedding in feces, but the mode of action behind this phenomenon is unclear. In this study, the effects of four Tasco levels (0, 1, 3, and 5%) on rumen microbiota and rumen/fecal E. coli O serogroups in rams were investigated. Rum...

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 ELM/hd/d; T4 = 120 g ELM/hd/d, respective...

The effects of probiotics, yucca extract, monensin and L-cysteine on rumen methanogenesis were determined by in vitro incubation using mixed bovine rumen microorganisms with ground Bermuda grass hay as a substrate. Two forms of probiotics, yucca extract, monensin and L-cysteine were tested during 24 hour anaerobic incubations. Methane and carbon dioxide production and fermentation characteristi...
