Pig production is one of the fastest growing livestock sectors. Development of this sector is hampered by rapidly increasing costs of fishmeal (FM), which is a common protein source in animal feeds. Here, we explored the potential of substituting FM with black soldier fly larval meal (BSFLM) on growth and blood parameters of pigs as well as economic aspects. At weaning, 40 hybrid pigs, i.e., crossbreeds of purebred Large White and Landrace were randomly assigned to five iso-nitrogenous and iso-energetic dietary treatments: Control (0% BSFLM and 100% FM (T0)), and FM replaced at 25% (T25), 50% (T50), 75% (T75) and 100% (T100) with BSFLM. Average daily feed intake (ADFI), average daily gain (ADG), body weight gain (BWG) and feed conversion ratio (FCR) were calculated for the whole trial. Hematological and serum biochemical parameters, the cost–benefit ratio (CBR) and return on investment (RoI) were evaluated. No significant effect of diet type was observed on feed intake and daily weight gain. Red or white blood cell indices did not differ among diets. Pigs fed T25, T75 and T100, had lower platelet counts compared to T0 and T50. Dietary inclusion of BSFLM did not affect blood total cholesterol, triglycerides, low-density lipoprotein and high-density lipoprotein. CBR and RoI were similar for the various diets. In conclusion, BSFLM is a suitable and cost-effective alternative to fishmeal in feed for growing pigs.

The experiment was carried out to determine the effect of replacement of maize with sweet potato (Ipomoea batatas lam.) on growth performance and cost of feeding weaner rabbits (Oryctolagus cuniculus). A total number of thirty-six (36) weaned rabbit of mixed sexes were used for the experiment. The rabbits were allotted randomly into four dietary treatments and replicated thrice with three rabbits per replicate and were designated: control (T): normal 1 compounded diet without sweet potato peel meal, T had the compounded feed which 5% 2 sweet potato peel meal, T had compounded diet with 10% sweet potato peel meal and 3 treatment four (T) had the compounded diet with 15% sweet potato peel meal. The 4 experiment lasted eight weeks and data were obtained on growth performance and cost benefit. The parameters considered on growth performance include initial weight, final weight, total body weight gain, daily weight gain, weekly weight gain, daily feed intake, total feed intake and feed conversion ratio while that of cost benefit include cost of purchasing different experimental feed stuff. The results obtained on growth performance showed that there were no significant differences (p>0.05) in the parameters monitored. Cost of feeding was also not significantly different (p>0.05). However, higher profit index (174. 64) was recorded in T1 and lower benefit cost ratio (166.68) was recorded in T4 for total cost of feed intake per rabbit. In conclusion, sweet potato peel meal can be uses as a good replacement for maize in rabbit production without any adverse effect on the performance of rabbit.

This study was carried out to determine the effect of object combination as environmental enrichment on behaviour of growing pigs. Thirty-six (36) crossbreed (Large White X Landrace) growing pigs with average weight of 34-36Kg were allotted randomly into four treatments, replicated three times in a completely randomized design. The four treatments were; Control (without enrichment), PRope (2 pieces of polyester rope), treatment SWood (2 pieces of soft wood) and treatment PRope+SWood (1 piece of soft wood and 1 piece of polyester rope). Behavioural observations were monitored by CCTV and recordings were made for 6 hours/day and 3days/week. At the end of the experiment, data collected includes average feed intake and average weight gain while feed conversion ratio was calculated. Likewise, behavioural observations; enrichment use, general activities, pen manipulation and pen-mate manipulation were observed. Behavioural data were analyzed using repeated measures analysis of variance (ANOVA) while performance data were analysed using one-way ANOVA. Performance data were significantly influenced (P<0.05) by enrichments for all the parameters measured. PRope+SWood had the highest value for the final weight (50.63kg), average weight gain (15.95kg) and average feed intake (56.61kg) while PRope had the highest FCR 4.18). Penmate manipulation (10.48%), pen manipulation (19.02%) and general activities (14.62%) were lower and significantly better for PRope+SWood compared to PRope and SWood and the highest interaction with enrichment objects was observed in the PRope+SWood (55.88%). It can be concluded that the use of combination of enrichment objects enhanced the performance and behaviour of pigs.

Abstract This experiment evaluated varying levels of Amarula (Sclerocarya birrea A. Rich) nut cake (ANC) on growth performance, nutrient digestibility and carcass characteristics in pigs. Thirty Large White × Landrace (LW × LR) pigs were stratified by weight (average live weight of 20 ± 5 kg) and randomly allocated to the five experimental diets that contained 0 (control), 50, 100, 150 and 200 g ANC/kg DM. Each pig served as a replicate unit, housed individually. Bodyweight, feed intake, average daily gain (ADG) and feed conversion ratio (FCR) were recorded weekly throughout the trial period. On completion of the growth trial, following a 3-day adaptation, a nutrient digestibility study was conducted over 5 days. Thereafter, pigs were fasted for twelve hours, weighed, slaughtered, and carcass samples were collected for analysis. Feed intake was not affected by dietary treatment, but ADGs were reduced at ANC levels > 15%, resulting in poor FCR. Protein digestibility was reduced at ANC levels > 15%, while ether extract and fibre levels increased. Warm and cold carcass weights were lower at ANC levels > 15, with improved meat redness and lightness. It was concluded that ANC could replace SBM in the diet of growing pigs at less than 15% inclusion level.

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.

A total of 48 large white pigs were used in an experiment to investigate the use of exogenous testosterone on the growth of pigs. The pigs were randomly selected as day old piglets, balanced for weight with equal number for each sex, and allotted to two treatment groups, T1, which received Testosterone Enanthate (TE), intramuscularly, weekly, for 24 weeks and T2, the control, which received no hormone but blank injections. Dosage was based on live weight (1.2mg/kg live weight). Corn oil served as the vehicle. The parameters measured include Total weight gain (TWG), Average Daily Gain (ADG), Average Daily Feed Intake (ADFI) and Feed Conversion Ratio. The results obtained showed that exogenous testosterone increased weight gain significantly (p<0.05) in both sexes than their respective controls. The same trend was observed for feed intake and feed conversion. Exogenous testosterone also indicated pronounced sex effect on the pigs in this study with males having significantly (p<0.05) higher values than females. It can be concluded from this study that exogenous testosterone can be used to accelerate growth thereby finishing the pigs early. A withdrawal period of 4 weeks before slaughter is however recommended.

ABSTRACTIn an experiment which showed that the results of a genotype comparison are influenced by the design of the test, 16 castrated male and 16 female pigs of each of Large White (LW) and Gloucester Old Spot (GOS) breeds were allocated equally among four treat- ments: WW—rationed by weight and slaughtered by weight; A A—rationed by age and slaughtered by age; AW—rationed by age and slaughtered by weight; and WF—rationed by weight and slaughtered after a common total feed intake. The experiment was designed so that performance of LW would be similar on all treatments, and the degree to which the GOS differed from the LW on each of these treatments was then evaluated. All pigs started on the experiment at 12 weeks of age, at which time mean weight of the LW was 14% greater than the mean for the GOS. The only between- breed difference that was statistically significant (P<0·05) on all treatments was weight of lean. Average daily gain and efficiency of feed conversion were significantly different between breeds only on the WW treatment. Weight of fat was significantly different on WW and AW but not on AA or WF.

This study was conducted to assess the effect of common salt supplementation on the performance of young sheep fed maize bran and ground nut hay as basal diet. It covered a period of 12 weeks. A 3×3 Latin square design was employed in the experiment. The daily feed intake, body weight gain and feed conversion efficiency were measured during the experimental period. Results showed that the inclusion of common salt at the level of 1.0% of feed had no significant effect on feed intake (p>0.05). There was depressed feed intake as quantity of salt increased from 0.0%, to 0.5% and 1.0%. The best mean average daily weight gain of 43.45%was obtained with the 1.0% treatment. Salt inclusion up to 1.0% level in sheep ration, had no adverse effect on performance, it rather gave a more favorable weight gain and conversion efficiency. These findings are of very practical significance in sheep fattening, especially for farmers in rural setups.

ABSTRACT The number of sheep flocks in Brazil is increasing. It is known that lambs must be slaughtered when young for producing quality meat. The current study evaluated the inclusion of protected methionine, protected lysine, lysophospholipid and amylolytic enzymes in a diet to lambs and their effects on weight gain and quantitative carcass traits at slaughtering. Eighty non-castrated male crossbred Dorper x Santa Inês lambs, 20.57 ± 4.33 kg live weight, were used. The feedlot lasted 64 days and 60 animals were slaughtered. There were no differences for live weight, daily feed intake, feed conversion and average daily weight gain at the first 28 days of feedlot. From the 28th day lysophospholipid treatment presented the highest live weight. Lysophospholipid and amylolytic enzyme presented the best performance in average daily gain, followed by protected methionine, control and protected lysine. Lysophospholipid treatment presented higher daily feed intake rates than protected lysine and protected methionine. Feed conversion was lower for amylolytic enzyme and higher for control. No changing in carcass traits was reported due to additives. Better performance may be achieved with feedlot lambs fed on diets with the addition of amylolytic enzyme and lysophospholipid at the finishing phase.
