    Effect of Different Floor Types on Growth Performance of Pigs and Carcass Back-Fat Thickness
    (London Journal of Research in Science: Natural and Formal, 2021) Kidega, K.; Aliro, T.; Mugonola, B.; Ndyomugyenyi, E. K.; Okello-Uma, I.
    Pig production (Sus scrofa domesticus) amongst smallholder farmers is constrained by poor growth performances in terms of feed intake (FI), weight gain (WG) and feed conversion ratio (FCR) and, high proportion of carcass back-fat thickness to lean meat. This study investigated the effect of floor types on growth performance of pigs and carcass back-fat thickness of pigs raised on IMO treated deep litter floor, untreated deep litter floor and concrete floor.Three-month old pigs (Large White x Landrace) were raised on a deep litter floor and concrete floor (control); one type of deep litter floor was treated with IMO solution and one type not treated. No significant (P≥0.05) difference were observed in feed conversion ratio (FCR), carcass back-fat thickness at the back from the 15th rib to the last Lumbar vertebrae, at gluteus medius muscle and the thigh of pigs raised on both concrete floor, IMO treated and untreated deep litter floor.

    Evaluation of the nutritional value of soaked-boiled fermented Java plum (Syzygium cumini) seed meal for poultry
    (African Journal of Agricultural Research, 2016-06-30) Ndyomugyenyi, E. K.; Okot, M. W.; Mutetikka, D.
    Chemical analysis, apparent metabolizable energy (MEn), and one feeding trial were conducted to evaluate the nutritional value of Java plum seeds (JPS) that had been subjected to a combination of soaking, boiling, and fermentation (SBF). Five broiler starter diets were formulated with the processed Java plum seed meal (JPSM) comprising 0, 80, 160, 240, and 320 g/kg of the diet. The JPS before and after processing contained 910±5.30 and 888±6.10 g DM; 44.2±0.940 and 48.1±1.02 g CP; 886±9.90 and 888±6.54 g NFE; and 13.2± 0.165 and 13.3±0.154 MJ calculated metabolizable energy; 24.4±1.33 and 9.17±0.940 g tannins per kg, respectively. The MEn value of the processed JPSM was 14.7±0.973 MJ/kg. Feed intake (FI), weight gain (WG), and feed efficiency (FCR) of broiler chicks decreased (R2 ˃ 0.850) with increasing JPSM in the diet. At 80 and 320 g/kg inclusion, FI, WG, and FCR were depressed by 16.0 and 34.1%, 20.2 and 42.5%, and 4.90 and 12.5%, respectively. Liver, heart, and pancreas weights relative to body weight were not significantly (P ˃ 0.05) affected. However, caecum, gizzard, and intestine weights increased (R2 ˃ 0.800), while the heart weight decreased (R2 = 0.772) with increasing JPSM in the diet. At 80 and 320 g/kg JPSM inclusion, weights of caecum, intestine, and gizzard increased by 48.5 and 68.2%, 18.8 and 43.5%, and 9.55 and 19.2%, respectively. Inclusion of JPSM in chick diets adversely (P < 0.05) affected nitrogen retention (NR), nitrogen digestibility (ND), dry matter digestibility (DMD), and excreta water content (EWC). At 320 g/kg JPSM inclusion, NR, ND, DMD, and EWC were depressed by 30.8, 12.6, 0.42, and 2.45%, respectively. No mortality was recorded at 320 g/kg JPSM inclusion. The SBF did not improve the nutritional value of JPS for poultry production.

    Impact of Community Action Research Project (CARP+1) on the livelihoods of smallholder pig farmers in northern Uganda
    (RUFORUM Working Document Series, 2021-12-06) Ndyomugyenyi, E. K.; Kidega, K.
    Pig production in Uganda is largely constrained by high feed costs, poor breeds, foul smell in pig houses, and the fact that markets are not reliable for live pigs and products. To address the constraints, the Community Action Research Project (CARP+1) introduced user-friendly interventions to smallholder pig farmers in northern Uganda. This study aimed to establish the impact of the CARP+1 interventions on pig production and livelihoods of the smallholder pig farmers. Data were collected from 75 purposively selected farmers out of the 109 who kept pigs at the start of the CARP+1. Structured questionnaires, observations and interviews were used to collect the data. The number of farmers who were not keeping pigs decreased by 85.8% as a result of CARP+1 intervention. Farmers who kept over 16 pigs increased (P≤0.05) from 0.00% to 3% after the intervention. Farmers who earned over Ugx 1,600,000 (annually) from pig production increased (P≤0.05) from 3.3% to 13.2% after the intervention. As a result of the CARP+1 intervention, pig farmers were able to pay school fees for their children (63.3%) and purchase foodstuffs for their families (56.7%). Pig farmers (96.7%) were able to use the knowledge they got from the CARP+1 to improve the housing condition of pigs using deep floor on which indigenous microorganism liquid was applied, formulate cheap feed from local feedstuffs and disease control. In conclusion, the CARP+1 intervention significantly improved pig production and livelihoods of smallholder pig farmers in northern Uganda.
