Document Summary

Learning outcomes: differences between forage and concentrate feeds, concept of physical effective fibre, pasture research. Concentrates: less concentrated with nutrients, higher fibre content, fibre: harder to digest, more concentrated with nutrients, lower fibre content but higher energy, concentrated in protein, energy and minerals. Requires diet of higher nutrient density with a higher proportion of concentrate feeds and less roughage (particularly for intensive poultry and pig production systems) C3: 1st compound after carbon fixation with 3c; temperate plants; lower in dry matter but higher quality. C4: 1st compound after carbon fixation with 4c; tropical plants; higher in dry matter but lower quality. C3 and c4 grasses hay, straw, silages, pastures. C3 and c4 legumes hay, straw, silages, pastures. Maize, barley, oats, molasses, rice, rye, sorghum, wheat (molasses: viscous product from refining sugarcane or sugar beets) Brewers grain (e. g. fermented weed with ethanol removed), canola meal, corn gluten, cottonseed, ddgs, feather meal, linseed meal, lupins, soybean meal, sunflower meal, urea.
