Nutrition of Small Ruminants on Rangelands

Phosphorus Nutrition of Ruminants

Most Australian soils are derived from parent material which is low in phosphorus. Soils of low phosphorus status support early maturing, grass dominant pastures with a short summer growth period and hence lengthy period of senescence. Phosphorus in these grasses may be as low as 0.02 g P/100 g OM during senescence (Robinson and Sageman 1967) and may only reach 0.15 g.P/lOO g OM during active g...

Toxicity of Crepis lacera in grazing ruminants

BACKGROUND Crepis lacera is a plant from the Asteraceae family that is common in the Mediterranean region. Farmers believe that this plant may be deadly to small ruminants in areas of southern Italy. However, scientific evidence is lacking, and no proof exists that C. lacera is toxic to ruminants. Necropsies conducted on four sheep revealed lesions in their livers and kidneys. RESULTS In the ...

Nutrition of ruminants

Developing production systems for ruminants using tropical feed resources requires an understanding of the relative roles and nutrient needs of the two-compartment system represented by the symbiotic relationship between rumen micro-organisms and the host animal. Fibre-rich, low-protein forages and crop residues are the most abundant and appropriate feeds for ruminants in the tropics. Strategie...

signed to alert university-based administrators of the value of poultry genetic resources. The committees’ present administrative goals include development of priority guidelines for repository deposits of semen at the Ft. Collins NAGP facility, development of poultry-specific parameters for the GRIN database, establishment and distribution of useful guidelines/advice for handling and cryoprese...
