The addition of ‘high quality’ complementary feedingstuffs to the diet of the post weaning pig can positively impact on growth and lean muscle deposition. The Maillard Reaction bonds amino acid and sugar molecules together, and is one of the major pathways in the chemical changes that occur in the cooking process. Cooking of feedingstuffs has been shown to improve the digestibility and nutritive value of a diet (Pickford et al, 1992). In this study, lysine (Lys), methionine (Met) and threonine (Thr) where chemically reacted with sugar molecules to give in vitro early Maillard Reaction Products (MRP). The aim of this study was to assess what effect the addition of a solution of these MRPs to a complementary feedingstuff (Matan XL) would have on overall diet digestibility and subsequent piglet performance.

And Performance

The role of diet selection by farmed deer in their nutrient intake and species selection, and the consequences for the management of forages, is considered. In common with sheep and cattle, sward surface height (SSH) is the most influential sward physical factor on the ability of deer to meet their daily nutrient demand from grazed pasture, and a SSH of 10cm is required for maximum intake and performance. Deer discriminate among pasture species, generally preferring legumes and herbs to grasses. The grass dominance and low proportion of clover in typical permanent pasture grazed by deer reflects their selection for clover and avoidance of grass. This dominance of grass and the difficulty deer face in selecting for alternative species that are present only in a low proportion may constrain intake even when sward height is not limiting. Summer-growing forage species such as red clover (Trif olium pratense), white clover (Tri folium repens), birdsfoot trefoil (Lotus corniculatus), sulla (Hedysarum coronarium) and chicory (Cichorium intybus) have high nutritive value, and result in high liveweight gains by deer when provided as specialist swards at critical feeding times. Recent studies indicate that ruminants prefer to eat mixed diets, and management systems that enable mixed grass-clover pastures with a high proportion of legume to be sustained under selective grazing by deer would provide high nutritive value and maintain a balance between winter and summer in the seasonal distribution of pasture dry matter production.

Mutant Genes

Cellulose and hemicellulose are the major structural carbohydrates present in forages and form between 30 and 60% of the forage component of ruminant diets. The complex network of structural carbohydrates and lignin generally leads to low digestibility and limits the efficient utilisation of forages by ruminants. This situation occurs in both developed and developing countries, and in the latter it is particularly pronounced as much of the forage component is based around the use of crop residues (Owen and Jayasuria, 1989). Because forage costs are significantly lower than those of other dietary ingredients, improving forage quality has been a major objective for many research programmes in both the developed and developing world. Improvements in forage quality have been sort through a number of different strategies. These have included conventional breeding techniques, which have included the integration of mutant genes, leading to the development of Brown Midrib varieties of maize and the use of chemical and biological additives. Enzyme supplements are commonly used to improve the nutritive value of feeds for non ruminants and as silage additives where they have been shown to improve silage fermentation, feed intake and performance. Recent work with ruminants has however focused on the use of enzyme supplements to improve feed efficiency by the use of “direct-fed” fibrolytic enzymes. This strategy involves the application of enzymes to feed at or only hours before feeding. These studies have yielded very variable production responses. For any new technology to be implemented widely, the responses achieved must provide an acceptable level of consistency and predictability. The current paper reviews developments in enzymology, production responses achieved and the effects on nutrient digestion.
