Traditionally in swine nutrition, analyses of starch and fiber have focused on assessing quantity; however, both have a wide range of functional properties making them underappreciated nutrients. Starch ranging from low to high amylose changes from rapidly digestible in the upper gut to poorly digestible but fermentable in the lower gut thereby changing from a source of glucose to VFA source. L...

in the first experiment, twelve species of the most plentiful and fresh seaweeds and one species of seagrass from the beach were collected at kingston, south australia. all species were then separately sun-and oven-dried and ground. the ground samples were analysed for dry matter, ash, organic matter, crude protein, crude fibers, ether extract and digestibility in vitro. the digestible and ...

Abstract The objective of the present study was to develop prediction equations for digestible energy (DE) and metabolizable (ME) in swine diets based on chemical compositions feces with no dietary information. A total 262 fecal samples obtained from growing pigs fed 27 4 experiments were used. mainly corn, soybean meal, other plant-originated feed ingredients. In digestibility experiments, uri...

Eighty first-litter sows in a commercial piggery were assigned to two feeding treatments during a 26-day lactation. A commercial diet containing an estimated 15% crude protein (CP), 0.65% lysine and 12.5 MJ digestible energy (DE)/kg was offered to sows in the control group which consumed 3.04 kg/day. Sows in the treatment group were given a higher quality diet containing 16.4% CP, 0.83% lysine ...

Barley is the grain base for pig production in Western Canada. Its successful use depends upon appropriate supplementation. Good barley contains only 90% of recommended digestible energy (DE) for growingfinishing pigs. Barley is highly variable in DE, protein and amino acid content, being affected by varietal, agronomic and climatic factors. High fibre content is associated with reduced DE cont...

build, maintain the body's structure and supply energy for vital activities. Protein tends to be the most expensive. The safest, simplest and cheapest source is the non protein nitrogen urea. It has been reported that one hundred grammes of urea are equivalent to 200g of digestible protein provided the remainder of the ration supplies enough readily usable energy (McDonald et al., 1995). The ce...

Distillers grains (DG) are an excellent ruminant feedstuff. They are an excellent source both of energy and protein. In the production of alcohol, the starch, which is about two-thirds the composition of corn grain, is fermented to alcohol and CO2. The remaining nutrients are then concentrated by a factor of three. Corn protein of 10% is concentrated to 30% and fat (oil) from 4 to 12%. Fiber is...

Pasture-based ruminant production systems are common in certain areas of the world, but energy evaluation in grazing cattle is performed with equations developed, in their majority, with sheep or cattle fed total mixed rations. The aim of the current study was to develop predictions of metabolisable energy (ME) concentrations in fresh-cut grass offered to non-pregnant non-lactating cows at main...
