Sugarcane bagasse and pith, by-product which the residue after rind removal, are highly lignified by products of the sugar and paper industries, are the most abundant by-product in Iran. The use of by-product in animal nutrition is necessity since it may increase the availability of feed for animal and avoid accumulation that contributes to environmental problems. The main nutritional constraints for these crop residues as animal feeds are their slow rate of digestion and low nitrogen content (Liu et al., 2000). Steam-pressure treatment cleavage the bounds between lignin and the other component of the cell wall, in order to improve it’s degradability by enzymes of the rumen microbial ecosystem. The aim of this study were to evaluate the effect of increasing dietary steam treated pith content on feed intake, milk yield and composition of lactating dairy saanen goats.

Feeding Systems

Wahed and Owen (1986) reported a 0.33 increase in barley straw dry matter (DM) intake when stall-fed goats were allowed to refuse 0.5 of the amount offered rather than the 0.2, or less, allowed in conventional ad lib feeding. This approach offers a possible strategy for maximising intake and improving utilization of straw in Third World countries developing stall feeding systems for goats based on crop residues and other by-products. Generous feeding of straw (say allowing refusal-rates of 0.5 of amounts offered) could be followed by the refeeding of refusals after treating them with ammonia.The experiment was undertaken to investigate refeeding straw previously refused by goats and to measure the effect of ammonia-treating such refusals on Intake and digestibility. Barley straw and refusals (0.5 of amount offered) of the same straw were chopped and half of each material treated with ammonia (0.11 of 330 g NH3/kg solution per kg straw in sealed plastic bags for 30 days).

AbstractRuminant production systems in developing countries could be classified into three categories: the extensive systems, systems incorporating arable cropping and systems integrated with tree cropping. Systems have evolved in response to the agro-ecological environment, the availability and type of land, nature of cropping patterns, frequency and intensity of cropping, area of uncultivated land and animal species and animal numbers.Smallholder livestock farmers in most developing countries appear to have adopted a mixed system that incorporates the traditional extensive system and the system that combines arable cropping with livestock. Both in Africa and in Asia, livestock production is an important component of traditional agriculture, complementing arable cropping. Livestock utilize existing food resources such as communal grazing lands which are marginal for arable cropping, crop residues and agro-industrial by-products. Besides supplying meat and milk, organic manure and draft power, livestock are an investment and an insurance against crop failure.Crop residues and agro-industrial by-products are a major source of nutrients for ruminant livestock in developing countries, especially during periods of fodder shortage. Despite the large research effort on upgrading crop residues in recent years, there has been little improvement in the utilization of crop residues in developing countries. Reasons for this are many but include, the absence of detailed production patterns of crop residues within countries, including when and where they are produced, the difficulties of transporting and storing crop residues, inappropriate technology and the near absence of extension services.Both in the African and Asian continents, smallholder farmers who rear livestock for supplementary income are rather reluctant to change their traditional practices, when new technologies call for extra labour, time and capital, since the methods may be too demanding in relation to the benefit produced. The more likely application of any new technology will be with larger-scale operations where benefits are clearer and sufficiently large to warrant the extra efforts.
