    Effects of inclusion levels of banana (Musa spp.) peelings on feed degradability and rumen environment of cattle fed basal elephant grass
    (Tropical animal health and production, 2016) Nambi-Kasozi, Justine; Nyambobo Sabiiti, Elly; Budara Bareeba, Felix; Sporndly, Eva; Kabi, Fred
    The effect of feeding varying banana peeling (BP) levels on rumen environment and feed degradation characteristics was evaluated using three rumen fistulated steers in four treatments. The steers were fed BP at 0, 20, 40, and 60 % levels of the daily ration with basal elephant grass (EG) to constitute four diets. Maize bran, cotton seed cake, and Gliricidia sepium were offered to make the diets iso-nitrogenous. The nylon bag technique was used to measure BP and EG dry matter (DM), crude protein (CP), and neutral detergent fiber (NDF) degradabilities at 0, 6, 12, 24, 48, 72, 96, and 120 h. Rumen fluid samples were collected to determine pH and volatile fatty acid (VFA) concentrations. Effective DM, CP, and NDF degradabilities of BP ranged between 574 and 807, 629–802, and 527–689 g/kg, respectively, being lower at higher BP levels. Elephant grass degradability behaved similarly with relatively high effective CP degradability (548– 569 g/kg) but low effective DM and NDF degradability (381–403 and 336–373 g/kg, respectively). Rumen pH and VFA reduced with increasing BP in the diets. Rumen pH dropped to 5.8 and 5.9 at the 40 and 60 % BP feeding levels, respectively. Banana peelings were better degraded than EG but higher BP levels negatively affected feed degradability and rumen environment.

    Low nutritive quality of own-mixed chicken rations in Kampala City, Uganda
    (Agronomy for sustainable development, 2014-01-17) Kasule, Lawrence; Katongole, Constantine; Nambi-Kasozi, Justine; Bareeba, Felix; Lindberg, Jan Erik
    Chicken production is popular in Kampala City, Uganda. Indeed about 70 % of all poultry products consumed in Kampala are produced locally. However, the high cost of feed is a major limiting factor. As a consequence, chicken farmers are formulating and mixing their own feeds. However, these own-mixed feeds may not meet recommended nutrient levels. We therefore studied five classes of own-mixed chicken feeds: broiler starter, broiler finisher, chick mash, grower mash, and layer mash. Samples of the chicken feeds were collected from farmers in and around Kampala City. We analyzed crude protein, ether extract, crude fiber, total starch, ash, calcium, phosphorus, and gross energy contents of the feeds. The apparent metabolizable energy content was calculated. We compared data with dietary requirements recommended for chickens in the tropics. Results show that own-mixed rations contained 21.9–36.3 % less protein than minimum recommendations. Broiler rations contained 16.2–20 % less metabolizable energy than minimum recommendations, and their crude fiber content was 37.5–50 % higher than the maximum recommendation. Layer mash contained 66.7 % less calcium and 17.5 % less metabolizable energy than minimum recommendations. All the five classes of own-mixed chicken rations were very high in ash content, ranging from 17.0 to 21.2 %. We conclude that own-mixed chicken rations do not conform to the dietary recommendations. There is therefore a need to give chicken farmers training on feed formulation and mixing.
