Ruminal inocula with distinct fermentation profiles differentially affect the in vitro fermentation pattern of a commercial algal blend

Frontiers in Veterinary Science
The in vitro rumen batch technique is widely used for screening novel feed sources; however, it remains unclear to what extent the in vitro fermentability of non-conventional feed sources is affected by non-adapted ruminal inocula.

Expression of a Recombinant Lentinula edodes Xylanase by Pichia pastoris and Its Effects on Ruminal Fermentation and Microbial Community in in vitro Incubation of Agricultural Straws

Frontiers in Microbiology, 2018
Agricultural straws, such as rice straw, wheat straw, and corn straw, are produced abundantly every year but not utilized efficiently in China. An experiment was conducted to determine the effects of recombinant xylanase on ruminal fermentation and ...

Feeding amylolytic and fibrolytic exogenous enzymes in feedlot diets: effects on ruminal parameters, nitrogen balance and microbial diversity of Nellore cattle

Journal of Animal Science and Biotechnology
Background The environmental impact of feedlot operations is a growing concern, as cattle excrete a significant portion of feed nutrients as waste.

Effect of alfalfa supplementary change dietary non-fibrous carbohydrate (NFC) to neutral detergent fiber (NDF) ratio on rumen fermentation and microbial function in Gansu alpine fine wool sheep (Ovis aries)

Animal Biotechnology
Bodyweight loss and rumen microbial dysfunction of grazing sheep was a challenge for the sheep production industry during cold season, which were considered to correlated with under-roughage-feeding. Alfalfa is a good roughage supplementary for ruminants,

The protection of the unsaturated fatty acids of dried grass and sunflower seed against biohydrogenation by rumen micro-organisms : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science in Animal Science at Massey University [PDF]

, 1974
Ryegrass which had been dried and treated with HCHO was incubated with the rumen contents of a pasture-grazed cow. The protein in the grass was protected from degradation by the rumen microbes.

Influence of Wheat Straw Pelletizing and Inclusion Rate in Dry Rolled or Steam-flaked Corn-based Finishing Diets on Characteristics of Digestion for Feedlot Cattle. [PDF]

, 2016
Eight Holstein steers (216±48 kg body weight) fitted with ruminal and duodenal cannulas were used to evaluate effects of wheat straw processing (ground vs pelleted) at two straw inclusion rates (7% and 14%; dry matter basis) in dry rolled or steam-flaked

Methane Production of Different Forages in Ruminal Fermentation

Asian-Australasian Journal of Animal Sciences, 2012
An in vitro rumen batch culture study was completed to compare effects of common grasses, leguminous shrubs and non-leguminous shrubs used for livestock grazing in Australia and Ghana on CH4 production and fermentation characteristics. Grass species included Andropodon gayanus, Brachiaria ruziziensis and Pennisetum purpureum.
