AIMS The aims of this study were to evaluate the host-specific distribution of Bacteroidales 16S rRNA gene sequences from human- and animal-related effluents and faeces, and to define a ruminant-specific marker. METHODS AND RESULTS Bacteroidales 16S rRNA gene clone libraries were constructed from samples of effluent (sewage, bovine manure and pig slurry) and faeces (human, bovine, pig and wil...

ranking of critical inputs was, for diet 1, SBM kd (r=-0.5), CS A fraction (r=-0.34), and dried corn kd (r=-0.25), for diet 2, SBM kd (r=-0.55), grass hay CP (r=0.32), and dried corn kd (r=-0.31). For the CNCPS, the ranking was, for diet 1, SBM kd of B2 pool (r=-0.5), dried corn kd (r=-0.26), and WB CP (r=0.26), for diet 2, SBM kd (r=-0.52), grass hay CP (r=0.36), and dried corn kd (r=-0.35).

This study was conducted to determine the effect of including mannan oligosaccharides (MOS, Bio-Mos r ) in diets fed to gestating and lactating sows on their productivity. A total of 80 gestating sows (Landrace × Large White), selected two weeks before the expected farrowing, were randomly allotted to one of two treatment groups taking into account their parity number. The two treatments were a...

Livestock have made major contribution to human societies by providing food, shelter, fuel, and services.  Sheep and goat are economically important livestock play an important socioeconomic role for small and large farmers in Libya.  Small ruminant animal meat is popular for Libyan customers, and demand is particularly high during religious and cultural festivals.  Small ruminants is valued fo...

A total of 45 lactating Holstein cows averaging 617 kg of BW were allotted at wk 20 of lactation to 9 groups of 5 cows blocked for similar DIM to determine the effects of feeding different concentrations of flax hulls (FH) on DMI, milk production, milk composition, and digestion. Cows within each block were assigned to one of the 5 isoenergetic TMR containing 0, 5, 10, 15 or 20% FH. The experim...
