Abstract

The extent of utilization of crop residues and agro-industrial by-products and the socio-economic constraints limiting their integration in crop- livestock production feeding systems in three agro-ecological zones (Lake Victoria Basin, Western Rangelands and the Eastern Semi-Arid Zone) of Uganda were examined. Data were collected from 150 randomly selected respondents using structured and semi-structured questionnaires. Farmers’ responses on the constraints faced in utilization of crop residues in the three agro-ecological zones was pooled and subjected to nonparametric statistics (Kruskal–Wallis one-way analysis of variance) to determine if significant differences existed between the different constraints. Utilization of agro-industrial by-products was highest in the LVB with 56% of the respondents reporting their use. The least levels of utilization of agro-industrial by-products were reported in the ESAZ by only 6.26% of the respondents. Maize bran and Dairy meal were the most utilized agro-industrial by-products reported by 36.33 and 31.3% of the respondents, respectively. Maize stover and banana peels were reported to be the most utilized crop residues for animal nutrition in the three agro-ecological zones. Most of these residues were produced on farmers’ farms with less than 5% of the farmers purchasing them. Highest utilization of maize stover (over 80% of respondents) was reported in the LVB followed by the ESAZ (32%). Banana peels were noted as the most utilized crop residues in the WR (79%). The study revealed that inadequate knowledge, poor quality and limited availability of agro-industrial by products and crop residues are major factors for limited use of the feed resources. Improving the utilization of agro-industrial by products and crop residues should therefore first target improving farmers knowledge and availing technologies for improving the quality of crop residues.
