| dc.description.abstract | The study was conducted in Machakel district, East Gojjam Zone, Amhara National Regional State. The objectives of the study were quantifying the production of traditionally brewery (atella) and distillery by-products (brint), evaluating the farmers’ utilization and perceptions of these by-products, studying their nutritional values in cross breed dairy cows under onfarm condition. A single-visit multiple subject survey method was used to collect data on production, feeding practices of these by-products and the main feed resources for their dairy cows. A total of five kebeles (3 rural and 2 urban-peri-urban) were purposively selected based on presence of SNV-BRIDGE project. A total of 272 respondents (126 from rural and 146 from urban-peri urban) with different wealth status were selected from these kebeles to administer survey questionnaire. Quantification of atella and brint production per year was carried out from 75 producers (53 for brint and 22 for atella) drawn from the two production systems, project participants, non-participants and each wealth group. The amount of wet atella and brint produced at a time was quantified, dried until constant weight and calculated to the annual production. On-farm feeding trial was conducted to evaluate the body weight change, milk production and chemical compositions of milk. Twelve mid lactation at third parity cross bred lactating cows with average initial body weight and milk yield, 413±4.17kg and 8.67±0.1l/c/day (Mean ± SE), respectively were selected for the feeding trial. The dietary treatments were T1 (wheat straw with concentrate as the control), T2 (wheat straw with atella only), T3 (wheat straw wit brint only) and T4 (wheat straw with 50%atella and 50% brint mixture). Among the non-conventional feeds brint was highly appreciated feed resources by 154 (56.66%) of the total respondents than atella. The feeding practices of brint and atella with crop residues were mixing of the wet by product with the crop residues with the ratio of 40% to 60% on DM basis. The ingredients for attela and brint production in the study area were the same, maize, wheat and Gesho. From the quantification, 2,065.14 qt brint and 57.9 qt atella totally 2,123.04 qt were produced from all these 75 farmers engaged for quantification yearly on DM basis. The average yield of brint and atella per household was 38.96 qt and 2.63 qt respectively on DM basis, which has 36.33qt higher brint than atella. The DM percentage for brint and atella were 16.68% and 13.8% respectively. The mean crud protein content of brint and atella sampled from the 75 farmers was 19.26±0.24 and 18.88±0.17 (Mean± SEM) respectively. On the other hand, the mean NDF content of brint and atella was 58.06±0.72 and 57.08±0.98 respectively. The crude protein content of brint and atella used in the feeding trial were 19.8 and 16.5% respectively while; the NDF content in brint and atella were 57.73% and 60.42% respectively. The result of the on-farm feeding experiment showed that; significant differences (P<0.05) was observed on average daily weight gain and the highest gain was from T3 (18kg/T) as compared to T2, T1 and T4. The lowest/reduction weight gain was observed on T2 (-13.66 g/d/T). Similarly a significant differences (P<0.05) effect on milk yield was observed among treatments. The highest average milk yield, (9.67 l/cow/day and 9.58 l/cow/day) was observed on T3 and T4 respectively; whereas the lowest milk yield (7.75 l/cow/day) was observed on T2. The partial budget analysis indicated that T3, T4 and T2 were economically feasible due to fair price of brint and atella. So; it can be concluded that brint by-product was better than atella both by farmers and on-farm feeding evaluation in terms of biological and economic response. Therefore; feeding of brint with crop residue and the mixture of atella and brint with crop residue were recommended for the dairy cows. | en_US |
