Twenty-four (24) indigenous growing pigs were selected and randomly divided into 4 treatment groups consisting of 6 animals in each group penned individually and provided with the facility of separate feeding and watering to each pig. Sweet potato (Ipomoea batatas) meal (roots and leaves at 1:1 ratio) was incorporated in the diet to replace standard pigs grower ration at 0% (G1), 25% (G2), 50%(G3) and 75% (G4). During the feeding trial of 90 days, it was observed that the average dry matter intake was higher in G2 followed by G3 and G1 being the lowest. The feed conversion efficiency and average daily gain decreased as the level of sweet potato meal increased. However there were no significant differences (P>0.05) among the different treatment groups in regards to feed conversion efficiency and average daily gain. From the digestibility trial, no significant differences (P>0.05) were observed in the digestibility co- efficient of dry matter, crude protein and crude fibre among the different treatment groups. It is concluded that sweet potato meal can replace standard pig grower ration up to 75% without any adverse effect on growth, feed conversion efficiency and nutrient utilization.

The efficacy of diatomaceous earth (DE) on growth rate, egg production and on increasing feed conversion efficiency in deep litter raised layer hens was evaluated. The study was conducted at Mukono Zonal Agricultural Research and Development Institute (MUZARDI) in Uganda. Worms were collected from fresh intestines of indigenous chicken obtained from Kalerwe chicken market near Kampala. The DE was mined in Pakwach (formerly Nebbi) district in Northern Uganda. Chickens of the Lohmann Brown breed raised on deep litter were studied. At 7 weeks the birds were divided into 5 treatment groups, A, B, C, D and E each composed of 40 birds. Groups C, D and E were given an oral dose containing 250 embryonated eggs of A. galli while groups A and B were not infected. The chicks were weighed; and subjected to feeding trials as arranged below: A – Non-infected birds on DE (4%) supplemented diet; B –non-infected birds on neither piperazine (a conventional de-wormer) nor DE; C – infected birds on DE supplemented diet; D – infected birds on piperazine; and group E – infected birds on neither DE nor piperazine applied. Fecal samples were collected and analysed in the laboratory biweekly at week 16 till week 22 respectively for fecal egg counts. In a subsequent experiment, day-old layer chicks from Lohmann Brown strain but different from those used in earlier experiments, were used to assess the effect of DE on egg production. At 17 weeks of age the 420 were divided as follows: 6 treatment groups each having 7 replicates and each replicate having 10 birds. This study showed that DE can be used successfully in growing pullet diets to correct nutritional mineral imbalance since it supplies more than 14 trace elements and other elements. Diatomaceous earth also enables pullets to cope with Ascaridia galli load; and 2% DE supplementation did not have significant improvement on egg production as compared to no supplementation at all. However, reduction in egg production was experienced when supplementation with levels of DE higher that 2% was applied. Results from biweekly fecal analyses showed significant differences in fecal egg counts (p<0.05); and treatment by group (p<0.05).

A series of experiments measured the effect of amino acid, copper, and vitamin B supplementation of 80 : 20 wheat--meat meal or wheat-meat and bone meal diets for Large White pigs during the growth phase between 18 and 45 kg liveweight. Diets were fed under a restricted feeding system. The addition of l-lysine to the diet increased nitrogen retention, liveweight gain, feed conversion efficiency, and lean content of the ham in experiment 1, and increased liveweight gain and feed conversion efficiency in experiment 2. No response to a lower level of l-lysine was obtained in a third experiment. There was no apparent effect of supplementary dl-methionine, either alone, or in combination with 1-lysine. A 21-fold increase in liver copper levels occurred in pigs supplemented with 250 p.p.m. copper, but no apparent effect on liveweight gain, feed conversion efficiency, or lean in the ham was detected. There was no apparent effect of a supplement containing riboflavin, pantothenic acid, and nicotinic acid on liveweight gain, feed conversion efficiency, or lean content of the ham.

The effect of feeding barley-wheat-soya finisher, gestation and lactation diets containing (A) 1979 National Research Council (NRC) recommended calcium-phosphorus (Ca-P) levels or (B) 150% of NRC levels from 65 kg body weight (Bwt) on growth and reproduction was studied in two experiments using Lacombe (L) and Yorkshire (Y) gilts. The number of gilts used were 299 (148 L + 151 Y) and 107 (53 Y + 54 Y) in exp. 1 and 216 (106 L + 110 Y) and 101 (49 L + 52 Y) in exp. 2 during finishing and gestation-lactation periods, respectively. The reproductive performance during second parity was measured only in exp. 2 using 85 (36 L + 49 Y) primiparous sows. All pigs were housed in confinement except during breeding and gestation, when they were housed in outside dirt-lot pens. Average daily gain, feed intake, and feed conversion were similar for gilts fed finisher diets A or B in both experiments. In exp. 1, both L and Y gilts fed gestation diet B had more (P < 0.05) total (9.5 ± 0.3 vs. 8.6 ± 0.3) and live pigs (9.2 ± 0.3 vs. 8.2 ± 0.3) born and weaned (7.7 ± 0.3 vs 6.9 ± 0.2) with lower piglet weight gains at 3 wk (3.5 ± 0.1 vs. 3.9 ± 0.1 kg) and 5 wk (6.9 ± 0.2 vs. 7.5 ± 0.2 kg) when compared to gestation diet A group. These differences were not significant in exp. 2. Higher dietary Ca-P levels elevated the serum P during both gestation (7.3 ± 0.1 vs. 7.0 ± 0.1 mg/dL) and lactation (6.2 ± 0.1 vs. 5.9 ± 0.1 mg/dL) periods in exp. 1 but not in exp. 2. The changes in body weight during gestation and lactation, piglet birth weights, and weaning to estrus interval were similar for both treatment groups. These results indicated that the 1979 NRC recommended dietary Ca-P levels may be adequate to support the maximum growth and reproduction in gilts during finishing and lactation but are too low for gestation.

SUMMARYAllowances of about 1·4M, 1·8M, 2·2M, 2·6M, 3·OM, and 3·4M (M = feed required for maintenance) were compared for pigs growing over the live-weight ranges 20·40, 40·60, 60·80, and 80·100 kg, with feed conversion efficiency (FCE) as the main response criterion.Response to increased digestible energy (DE) allowance was curvilinear; FCE improved rapidly up to 2·2M-2·6M, and changed much less with intakes above 2·6M. It is concluded that optimum FCE occurs at about 2·7M for pigs of 30 kg and at about 3·OM for pigs of 50, 70 and 90 kg.Allowances of dietary DE suggested by the Agricultural Research Council correspond to 2·56M, 2·95M, 3·04M and 3·08M for pigs of 30, 50, 70 and 90 kg live weight, respectively. It appears that these are near to the optima in promoting the best FCE.Changes of −25%, −15%, −5%, +5% and +15% in daily intake around the optimum levels caused FCE to deteriorate by averages of about 13%, 4·5%, <1%, <1% and 4·5% respectively. Daily weight gains would then change by about −34%, −18%, −5%, +4% and +10%, respectively.

This study was carried out to evaluate the feeding effect of high yielding fodders (HYF) on feed intake and growth performance of growing Hilly Brown Bengal (HBB) goat. For this purpose, a feeding trail was conducted with 16 growing HBB kids (4 to 5 months) by dividing equally in four groups having four replicates for a period of 75 days. The goats in group T0 (control) received natural grass along with 101.30g concentrates and adlibitum cowpea hay, whereas in group T1, T2 and T3, only natural grass was replaced by BLRI Napier 3, BLRI Napier 4 and Ruzi fodder, respectively. Total dry matter intake (DMI), roughages DMI, crude protein intake (CP), body weight gain (kg), average daily gain (g) and forth night body weight gain (g/day) were studied. Results revealed that, DMI (288.39, 285.71, 293.48 and 301.35 g/day in group T0, T1, T2 and T3, respectively), body weight gain (3.60, 3.74, 3.73 and 3.77 kg in group T0, T1, T2 and T3, respectively), average daily gain (47.32, 49.16, 49.12 and 48.92 g in group T0, T1, T2 and T3, respectively) and feed conversion ratio (6.2, 5.9, 6.0 and 6.1 in group T0, T1, T2 and T3, respectively) of HBB kids were not differed significantly (P>0.05) for all the treatment groups. The DMI from roughages (196.2, 193.5, 201.3 and 209.2 g/day in group T0, T1, T2 and T3, respectively) and CP intake (38.7, 42.1, 48.3 and 38.8 g/day in group T0, T1, T2 and T3, respectively) were significantly varied (P<0.05), while highest CP intake was found in the treatment group T2. Forthnight body weight (g/day) was not significantly (P>0.05) gained with feeding of HYF for all the treatment groups. From this study, it can be concluded that, growing HBB kids could equally be supplied with either BLRI Napier 3 or BLRI Napier 4 or Ruzi fodder in addition to ad libitum cowpea hay for better voluntary feed intake and growth.

The study aimed to evaluate growth performance of grower pigs fed fermented liquid potato hash with or without exogenous enzyme. Diets containing either 200 (LFLPH) g/kg potato hash (enzyme treated or not); 400 (HFLPH) g/kg potato hash (enzyme treated or not) or no fermented potato hash (control) were formulated to provide 14 MJ/kg digestible energy (DE), 180 g/kg crude protein (CP) and 11.6 g/kg lysine. Dietary treatments were control (no FLPH), enzyme treated LFPHE and HFLPHE, and untreated LFLPH and HFLPH. The exogenous enzyme was added in treated diets to provide minimum of 560-840 TXU/TDU xylanase per kg feed, at an inclusion rate of 100 g/tonne. Diets were mixed with water at 1:2 ration and fermented for 8 hours at 25 °C room temperature before being fed to pigs. Back-slopping fermentation approach was followed to prepare diets. Twelve pigs (25±2.3 kg) per diet that were individually housed were fed ad-lib for eight weeks. Pigs were allocated to diets in complete randomized design. Average daily gain (ADG), average daily feed intake (ADFI) and feed conversion ratio (FCR) were measured. The enzyme treated FLPH diets had higher (P < 0.05) CP, lower (P > 0.05) NDF and ADF concentrations compared to untreated FLPH diets. The LFPHE diet had higher (P < 0.001) final weight, ADG and lower (P < 0.001) ADFI and FCR compared to LFPH, HLFPH and HLFPHE. It was concluded that LFPHE diet may be an alternative feed source for growing pigs as indicated by higher gain and lower intake compared to LFLPH, HFLPH and HFLPHE.

This study aimed to (1) investigate the effect of birth and weaning body weight (BW) on performance indicators of grow-finisher pigs and (2) estimate birth and weaning BW cut-off values in order to identify slow growing pigs (SGP). Pigs (n = 144) were classified as SMALL (0.9 ± 0.13 kg) or BIG (1.4 ± 0.20 kg) at birth and re-classified as SMALL (5.4 ± 1.6 kg) or BIG (6.3 ± 1.91 kg) at weaning. Individual BW was recorded bi-weekly, and feed intake was recorded on a daily basis. Average daily gain (ADG) and feed intake, feed conversion ratio (FCR) and days to target slaughter weight (TSW) were calculated. SMALL–SMALL pigs had lower ADG (p < 0.05) requiring 167.1 days (i.e., 14.2 extra days) to TSW (p < 0.05) compared with BIG pigs at birth and/or weaning. However, FCR was similar between groups (p > 0.05). Pigs weaned at <3.7 kg BW would likely be SGP. Pigs born at ≥1.1 kg BW or weaned at ≥6.4 kg BW are more likely to reach TSW at 22 weeks of age. The results suggest that birth BW might not be the best predictor for subsequent performance, as some small-born pigs were able to catch up with their bigger counterparts. The cut-off values identified could be used to design specific management and nutritional strategies for SGP.

The response to dietary lysine of liquid or crystalline form was examined in pigs fed on cereal protein dietsover the range of live weight from 25.0 to 95.0 kg. Forty individually fed growing pigs (20 gilts and 20castrated males) were allocated to four isonitrogenous diets consisting of barley, undehydrated distillers solids and a mixture of minerals and vitamins with lysine supplementation of 0.9 or 3.2 g pure lysine per kg DM in liquid or crystalline form to provide 7.1 or 9.1 g/FU total lysine, respectively. The pigs were given feed on a restricted scale twice daily. A high level of lysine supplementation significantly increased the growth rate and improved the feed conversion efficiency (p
