In this study, the effects of rumen-protected fat (RPF) were evaluated as an energy source for partial replacement grain feed in diets Merino male lambs during hot season. Fourteen six months old weighing average 29.59 kg randomly allocated into two groups: control diet (CON) and supplemented with 30 g/kg RPF. Live weight (LW), dry matter intake (DMI) daily gain (ADG) recorded, conversion ratio...

Two experiments were carried out to determine the effects of feeding grass silages differing in their water-soluble carbohydrate content, with or without red clover silage, on the efficiency of nutrient use. High-sugar grass, control grass, and red clover were ensiled in laboratory silos for use in an in vitro experiment (Exp. 1). For an in vivo experiment (Exp. 2), the same forage types were b...

Green and black tea by-products, obtained from ready-made tea industry, were ensiled at 10°C, 20°C, and 30°C. Green tea by-product silage (GTS) and black tea by-product silage (BTS) were opened at 5, 10, 45 days after ensiling. Fermentation characteristics and nutrient composition, including tannins, were monitored and the silages on day 45 were subjected to in vitro ruminal fermentation to ass...

Fresh Lotus corniculatus containing 27 g extractable condensed tannin (CT)/kg dry matter (DM) and 8 g bound CT/kg DM was fed at hourly intervals to sheep held in metabolism cages to study the effects of CT on nutrient digestion and on metabolism of methionine, cystine and inorganic sulphate in plasma. Polyethylene glycol (PEG) was continuously infused into the rumen of half the sheep to remove ...

The purpose of the present review is to examine the role played by nutrients in controlling feed intake in ruminants, in light of their particular anatomical, physiological, nutritional and behavioural characteristics. The ration is first digested in the rumen for several hours by microbial fermentation. Volatile fatty acids, which constitute 50-75% of a ruminant's energy supply, considerably d...

This study evaluated the effect of increasing the proportion of bison relative to cattle inoculum on fermentation and microbial populations within an artificial rumen (Rusitec). The experiment was a completely randomized design with a factorial treatment structure (proportion cattle:bison inoculum; 0:100, 33:67, 67:33, and 100:0) replicated in two Rusitec apparatuses (n = 8 fermenters). The exp...

In this study, milk and rumen liquor of stray cattle were found to contain measurable concentration of PolyChlorinatedBiphenyls (PCB). A notable finding in this study is that stray cattle have high level of PCBs where as the PCB in control group can not be detected. Since, reduction in space in the urban areas has pushed the cattle population to fend themselves in the streets, bovine milk act a...

Abstract Finishing cattle are exposed to diets with high amounts of starch and consequently hindgut acidosis. Usually, antibiotics like ionophores used control dysbiosis at gut level. However, natural options being evaluated as healthy alternatives. Flavonoids well known antibacterial agent, an interesting alternative antibiotics. The aim this experiment was evaluate the performance finishing s...
