The growing concern about the cost of feed ingredients, use of least cost feed formulation and maintenance of a reliable nutritional requirement for broiler birds irrespective of the season is almost compelling to look for alternatives. Thus, this experiment was conducted to evaluate the performance of broiler chickens fed rice milling waste (RMW) as a replacement for maize. Chemical composition of rice milling waste was determined, while eleven experimental diets each were formulated to contain RMW as replacement for maize at 0%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% and 100%. Three hundred (300), 7-day-old chicks were allocated to the 11 dietary treatments each having 3 replicate pens with 10 birds per pen in a Completely Randomized Design (CRD). Feed and water were provided ad libitum for 6 weeks. Growth performance, carcass yield, organ proportions and economics of production were monitored. Data were subjected to ANOVA at P<0.05. The result from the chemical composition showed that rice milling waste has 89.84% dry matter, 10.80% crude protein and 24.09% crude fibre, while the gross energy was 3789 kcal/g, this showed that RMW is suitable as feed ingredient and as well would not hinder absorption and nutrient utilization. The result of the growth performance showed that broiler chickens fed 10% - 40% RMW had greater average daily weight gain (55.33g- 47.97g), reached a greater slaughter and carcass weight (1500g – 1650g) and were more feed efficient than broiler chicken of the other treatments (P<0.05 for each). In addition, from an economical point of view birds fed 10 - 40% were superior to the other treatments where the cost/kg weight gained (N292.21K – N315.96K) were lower than the remaining treatment groups. Thus, the inclusion of RMW in diet of broiler chickens as a replacement for maize improved nutrient utilization and economic value. It can therefore be recommended that RMW can be used to replace maize between 10% -40% in the diets of broiler chickens.     La préoccupation croissante au sujet du coût des ingrédients alimentaires, de l'utilisation de la formulation d'aliments pour animaux les moins coûteux et du maintien d'une exigence nutritionnelle fiable pour les oiseaux de gril, quelle que soit la saison, est presque convaincante pour chercher d'autres solutions. Ainsi, cette expérience a été menée pour évaluer la performance des poulets à griller nourris aux déchets de fraisage du riz (le 'RMW') comme remplacement du maïs. La composition chimique des déchets de fraisage du riz a été déterminée, tandis que onze régimes expérimentaux ont été formulés pour contenir le 'RMW' comme remplacement pour le maïs à 0%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% et 100%. Trois cents (300), poussins de 7 jours ont été alloués aux 11 traitements diététiques ayant chacun 3 stylos de répétition avec 10 oiseaux par stylo dans un design complètement randomisé (CRD). L'alimentation et l'eau ont été fournies ad libitum pendant 6 semaines. Les performances de croissance, le rendement de la carcasse, les proportions d'organes et l'économie de la production ont été surveillés. Les données ont été soumises à ANOVA (P<0.05) Le résultat de la composition chimique a montré que les déchets de fraisage du riz ont 89,84% de matière sèche, 10,80% de protéines brutes et 24,09% de fibres brutes, tandis que l'énergie brute était de 3789 kcal/g, ce qui a montré que le 'RMW' est approprié comme ingrédient d'alimentation et ainsi n'entraverait pas l'absorption et l'utilisation des nutriments. Le résultat de la performance de croissance a montré que les poulets a griller nourris 10% - 40% RMW avaient un gain de poids quotidien moyen plus élevé (55.33g- 47.97g), ont atteint un plus grand poids d'abattage et de carcasse (1500g - 1650g) et étaient plus économes en aliments pour des animaux que le poulet de gril des autres traitements (P<0.05 pour chacun). En outre, d'un point de vue économique, les oiseaux nourris de 10 à 40 % étaient supérieurs aux autres traitements où le coût/kg de poids gagné (N292.21 K – N315.96 K) était inférieur à celui des autres groupes de traitement. Ainsi, l'inclusion du RMW dans l'alimentation des poulets de poulet a griller comme remplacement du maïs a amélioré l'utilisation des nutriments et la valeur économique. Il peut donc être recommandé que le 'RMW' peut être utilisé pour remplacer le maïs entre 10% -40% dans les régimes des poulets à griller.

Twelve Large White × Landrace sows nursing litters of 6 boars and 6 gilts were used in this study. Six litters suckled the sow only, whereas the other 6 litters received supplemental liquid skim milk (200 g/L) ad libitum from Day 10 until Day 20. On Day 20 the 4 heaviest pigs of each sex were allocated to 2 pairs and were weaned. Each pair was offered either pelleted or pelleted plus liquid feed. For the first 2 days post-weaning, each pair of liquid-supplemented pigs received liquid skim milk (250 g/L). On Day 23, pelleted feed was added to the milk. The ratio of liquid to pelleted feed was adjusted daily until, on Day 28, pigs were provided with pelleted feed only until 41 days of age. Supplemental skim milk increased growth (223 v. 291 g/day, P < 0.001) between Days 10 and 20 of age so that by weaning supplemented pigs were 10% (6.13 v. 6.74 kg, P = 0.038) heavier than unsupplemented pigs. Skim milk intake increased linearly from 190 to 600 g/day per pig over the 10 days of supplementation. Supplemental milk feeding did not alter sow liveweight change (−31.9 v. −30.3 kg for sows nursing litters with and without supplementation, respectively, P = 0.894) or change in P2 backfat thickness (−5.3 v. −4.2 mm, P = 0.279) between farrowing and Day 20 of age. Pigs weaned onto skim milk and pellets ate more (257 v. 30 g dry matter (DM)/day, P < 0.001) and grew better (213 v. −151 g/day, P < 0.001) over the first 2 days post-weaning than pigs weaned onto only pellets. Piglets provided with liquid feed after weaning continued to grow faster beyond Day 22, resulting in the benefit of weaning onto liquid feed being maintained until at least 41 days of age (14.1 v. 12.8 kg, P < 0.001). In conclusion, skim milk feeding before and after weaning can result in cumulative improvements in growth performance in the nursery.

A study was carried on 24 piglets (Large White York Shire × Desi) of an average initial weight of 20 kg of three gender groups, barrows, boars and gilts consisted of eight pigs each, of comparable body weight fattened from 20-48 kilograms (growing) to 49-96 kilograms (finishing) to see the effect of gender on growth performance, nutrient utilization and carcass traits. When comparing feed intake at the growing stage, gilts consumed significantly more (P less than 0.05) feed than boars and barrows. There was no significant difference in average daily weight gain among barrows, boars and gilts in growing and finishing stage. Gilts had significantly higher (P less than 0.05) feed conversion ratio than boars in growing period and barrows in finishing period. Nutrient digestibility was similar except crude protein among groups. Fasting weight and weight after bleeding was significantly lower (P less than 0.05) in gilts with nonsignificant difference between barrows and boars. Sex has no significant effect on evisceration weight, dressing percentage and carcass length in pigs. Carcass backfat of barrows was significantly thicker (P less than 0.05) than that of boars and gilts, however, the loin eye area was significantly larger (P less than 0.05) in gilts than boars and barrows. There were no significant differences among groups concerning the proportions of ham, under cut, bacon and rib chop however, shoulder and loin percentages were higher (P less than 0.05) in gilts than boars and barrows.

This study was conducted to investigate the effect of dietary copper and probiotic supplementation on growth performance and carcass characteristics of broiler Chickens. A total of 180-day old marshal broiler chicks of mixed sex were randomly allotted to six treatment groups of 30 birds each. The Treatments were divided into three replicates of ten birds each; starter and finisher diets were formulated and fed for a period of fifty-six days. The dietary treatments were subjected to completely randomized design experimental layout which was made up of probiotic (0 and 500ppm) and copper (0, 125 and 250mg).The chicks were fed the broiler starter diet for the first 28 days and broiler finisher for the last 28 days. Treatment effect on broiler body weight, feed intake and feed conversion ratio were determined on a weekly basis. Data obtained were analyzed using analysis of variance (ANOVA) and, Duncan's Multiple Range Test was used to separate significant means. Dietary supplementation of copper and probiotic had no significant (P> 0.05) effect on final weight (FW), daily weight gain (DWG), feed intake (FI), and feed conversion ratio (FCR) at the starter phase of the experiment. However, at finisher phase, inclusion of probiotic resulted in higher significant (P < 0.05) values for FW (2214.12g/b) DWG (60.22g/b/d), FI (159.02g/b/d), and FCR (2.64). The carcass yields of the broilers were significantly (P< 0.05) influenced by copper and probiotic supplementations. However, lower value (1.07%) was obtained for abdominal fat in broilers fed 250mg Cu/kg supplemented diet. The study concluded that supplementation of copper and probiotics resulted in improved growth performance and carcass yield of broiler chickens.

A 56 –day study was conducted to determine the growth performance and nutrient utilization of broiler chickens fed with two varieties (white and yellow) of cassava grit based diets. A total of 240 one day- old unsexed Arbor acre broiler chicks were assigned to eighty dietary treatments in a 2 x 4 factorial arrangement using completely randomized design. Diets were formulated to include two varieties of cassava, TME 419 (white) and TMS 01 1368 (yellow) at four inclusion levels (0, 25, 50 and 75%). Each treatment consisted of 30 birds and three replicates of 10 birds each. Data was collected on growth performance and nutrient digestibility at the end of the starter (4th week) and finisher (8th week) phases. At the starter phase, birds fed 50% white cassava grits diet had the highest (P < 0.05) final weight and weight gain (730.00 and 693.67g/bird). At the finisher phase, birds fed 50% yellow cassava grits diet had the highest (P < 0.05) final weight and weight gain (2235.60 and 1454.00g/bird), respectively while the least final weight and weight gain values (2008.80 and 1267.80g/birds) were obtained in birds fed the control diet. At the starter phase, birds fed 75% white cassava grits diet had the best (P < 0.05) feed conversion ratio of 2.18, while birds fed 25% yellow cassava grits diet as well as those fed the control diet had the least (P < 0.05) feed conversion ratio of 2.62 and 2.51 respectively. Birds fed 50% yellow as well as those fed 75% yellow cassava grits diets had the highest dry matter and crude fibre digestibility at the starter and finisher phases, respectively. In conclusion the substitution of maize with white cassava grits up to 50% level improved growth performance at the starter phase. However, either white or yellow cassava can be substituted for maize up to 75 % at the finishing phase.

The study was conducted in poultry production unit of the Teaching and Research farm in the Department of Animal Science, Faculty of Agriculture, Usmanu Danfodiyo University to investigate the effect of graded levels of kapok seed meal on broiler bird’s performance. A total of 288 broiler chickens were being used. The broiler chickens randomly divided into four treatments groups (four experimental diets) T1 (control), T2 (0.5kg/100kg), T3 (1Kg/100kg) and T4 (1.5kg/100Kg). At the termination of the experiment (day 56), two birds from each pen (replicate) having representative weights for the group (6 birds per Treatment) were selected. The selected birds were bled, dressed and eviscerated. At starter phase the result shows no significant difference (P>0.05) between the treatments with regards to final body weight and average daily weight gain, birds in treatment 4 had higher (P<0.05) feed conversion ratio (FCR) compared to the other treatments. The result shows significant difference (P<0.05) between the treatments across all the parameters measured except FCR. Birds fed treatment 4 record higher values (P<0.05) of all the parameters measured compared to treatment 1 at finisher phase. The result on carcass shows significant difference (P<0.05) in terms of liver, lung, spleen and crop. Birds in treatment 2 have lower (P<0.05) liver compared to the other treatments. Higher (P<0.05) crop weight are recorded for birds in treatment 1 compared to the other treatments. The study concludes that ingredients of kapok (Bombax costatum) in poultry diet significantly (p<0.05) improved performance of broiler birds at starter and finisher phase at rate of 0.5kg/100kg inclusion of fed.

Growth performance and survival of Tor putitora fry under different stocking densities were evaluated fry rearing system. The experimental period was 10 weeks from 31 December to 10 March 2019. The experiment was carried out in nine earthen ponds of 0.04 ha each under three treatments with three replications.  Thirty days old fry were stocked at the rate of 1.0X105/ha was designated as treatment- 1 (T1), 1.5X105/ha` as treatment- 2 (T2) and 2.0X105/ha as treatment- 3 (T3), respectively. Fry were fed with commercially available nursery feed containing 32% crude protein. It was observed that, lower stocking density showed highest daily weight gain in T1 (growth 0.066 ± 0.006 g/day) compared with higher stocking density in T2 (growth 0.044 ± 0.004 g/day) and T3 (growth 0.024 ± 0.003 g/day), respectively. It is also noticed that, the lower stocking showed the highest survival rate (79.66 ± 4.34 %) than the other two treatments (66.97±3.67 and 54.67± 3.12 %). The values of different water quality parameters were within the optimum ranges for the rearing of carp fry. Water quality parameters did not show significant variations in the experimental ponds under different stocking densities. Among these three stocking densities lower stocking density (T1) showed the best result compare with the other two higher stocking densities.

Consumption of high-fibre diet with non-starch polysaccharides (NSP) has the potential to adversely affect energy and nutrient utilization with consequent reduction in pig performance. This study was carried out to investigate the efficacy of three different enzymes cocktail on growth performance of growing pigs fed high-fibre diets.The basal diet served as control (T1). Treatment 2 (T2) contained 0.3 g/kg diet of A (Xylanase, Cellulase, Protease, Alpha-amylase, Beta-glucanase, Phytase and Pectinase), treatment 3 (T3) contained 0.5 g/kg diet of B (Carbohydrases, Beta-glucanase, Pectinase, Protease) while treatment 4 (T4) contained 0.25 g/kg diet of C (Xylanase, Phytase, Alpha – amylase, Protease, Bacillolysin).Sixty grower pigs of an average initial weight of 26.06 ±0.78 kg were randomly assigned to four dietary treatments (T) in a completely randomized design with three replicates per treatment and five animals in each replicate. Feed and water were supplied ad libitum. Feed intake and weight gain of the pigs were monitored weekly. Data were subjected to analysis of variance (ANOVA) using the General Linear Model procedures of SAS (2002).There were no significant differences (P>0.05) in the performance indices of the pigs though those fedenzyme cocktails had improved daily weight. Lowest feed cost per kg weight gain (? 345.38/kg) was observed in pigs fed diet supplemented with enzyme cocktail at 0.25g/kg. It was concluded that cocktail of enzymes improved daily weight gain of growing pigs fed diets containing non-starch polysaccharides. Also, enzymes cocktail (0.25g/kg) reduced feed cost per kilogram weight gain of the pigs.     La consommation d'aliments riches en fibres avec des polysaccharides non amylacés (NSP) a le potentiel d'affecter négativement l'utilisation de l'énergie et des nutriments avec une réduction conséquente des performances des porcs. Cette étude a été réalisée pour étudier l'efficacité de trois cocktails d'enzymes différents sur les performances de croissance de porcs en croissance nourris avec des régimes riches en fibres. Le régime de base a servi de contrôle (T1). Le traitement 2 (T2) contenait 0,3 g/kg de régime A (Xylanase, Cellulase, Protéase, Alpha-amylase, Bêta-glucanase, Phytase et Pectinase), le traitement 3 (T3) contenait 0,5 g/kg de régime B (Carbohydrases, Bêta -glucanase, Pectinase, Protease) tandis que le traitement 4 (T4) contenait 0,25 g/kg de ration de C (Xylanase, Phytase, Alpha amylase, Protease, Bacillolysin). assignés à quatre traitements diététiques (T) dans une conception complètement randomisée avec trois répétitions par traitement et cinq animaux dans chaque répétition. La nourriture et l'eau étaient fournies ad libitum. La prise alimentaire et le gain de poids des porcs ont été surveillés chaque semaine. Les données ont été soumises à une analyse de variance (ANOVA) à l'aide des procédures du modèle linéaire général de SAS (2002). Il n'y avait pas de différences significatives (P> 0,05) dans les indices de performance des porcs bien que ceux nourris avec des cocktails enzymatiques aient amélioré leur poids quotidien. Le coût alimentaire le plus bas par kg de gain de poids (? 345,38/kg) a été observé chez les porcs nourris avec un régime supplémenté avec un cocktail d'enzymes à 0,25 g/kg. Il a été conclu que le cocktail d'enzymes améliorait le gain de poids quotidien des porcs en croissance nourris avec des régimes contenant des polysaccharides non amylacés. De plus, le cocktail d'enzymes (0,25 g/kg) a réduit le coût des aliments par kilogramme de gain de poids des porcs.

Watermelon rind is one of the several unwanted by-products generated by restaurants, fruit juice producers and food industries in Nigeria that can be gotten rid of by using it as an energy source in broiler production. The growth performance and apparent nutrient digestibility of broilers fed diets containing varying inclusion levels of dried watermelon rind (DWMR) in replacement for wheat offal as source of energy and fibre at starter phase was evaluated. The dried watermelon rind was prepared by sun-drying fresh watermelon for three days and oven-dried at 50 ºC for 2 hours. The birds were randomly allocated to five (5) treatments (T1 – T5), each treatment had three replicates with ten (10) birds per replicate. The birds were fed varied levels of DWMR at 0 %, 25 %, 50 %, 75 % and 100 % in replacement of wheat offal to obtain five diets. Feed and water were provided ad-libitum throughout the 28 days study duration. Body weight, Body weight gain, Feed intake, Feed conversion ratio and apparent nutrient digestibility were measured. The results obtained on the growth performance shows no significant (P>0.05) difference of the growth parameters across treatments. However, there was significant (P<0.05) difference in the digestibility of Crude fibre, Ether extract, Ash, Nitrogen free extract and Total digestible nutrient across treatments. There was no obvious variation in dry matter and crude protein digestibility. The result of the total digestible nutrient was significantly (P<0.05) higher in T2 (92.90 %) than the T1 (84.99 %) which was the control diet. The crude fibre digestibility recorded in T2 (63.48%) and T1 (61.09 %) is higher than T5 (43.00 %), the ether extract digestibility of T1 (96.42 %) is higher than the other groups with the lowest in T4 (95.25 %). There was depress ash digestibility in T5 (68.30 %), lower than the other groups with the highest in T1 (82.59 %). The study therefore concluded that farmers can replace wheat offal with 25 % watermelon rind in broiler starter diet without any deleterious effect in the growth performance and nutrient digestibility.     La croûte de pastèque est l'un des nombreux sous-produits indésirables produits par les restaurants, les producteurs de jus de fruits et les industries alimentaires au Nigéria qui peuvent être débarrassés en l'utilisant comme source d'énergie dans la production de poulets à griller. La performance de croissance et la digestibilité apparente des éléments nutritifs des poulets de grillage nourris selon des régimes alimentaires contenant différents niveaux d'inclusion de la croûte de pastèque séchée (DWMR) en remplacement des aals de blé comme source d'énergie et de fibres à la phase de démarrage ont été évaluées. La croûte de pastèque séchée a été préparée par pastèque fraîche séchée pendant trois jours et séchée au four à 50ºC pendant 2 heures. Les oiseaux ont été attribués au hasard à cinq (5) traitements (T1 - T5), chaque traitement avait trois répliques avec dix (10) oiseaux par réplique. Les oiseaux ont été nourris à des niveaux variés de DWMR à 0 %, 25 %, 50 %, 75 % et 100 % en remplacement des aals de blé pour obtenir cinq régimes alimentaires. L'alimentation et l'eau ont été fournies ad-libitum tout au long de la durée de l'étude de 28 jours. Le poids corporel, le gain de poids corporel, l'apport alimentaire, le rapport de conversion des aliments pour animaux et la digestibilité apparente des nutriments ont été mesurés. Les résultats obtenus sur la performance de croissance ne montrent aucune différence significative (P>0.05) des paramètres de croissance entre les traitements. Cependant, il y avait une différence significative (P<0.05) dans la digestibilité des fibres brutes, extrait d'éther, cendres, extrait sans azote et nutriment digestible total entre les traitements. Il n'y avait aucune variation évidente dans la matière sèche et la digestibilité brute de protéine. Le résultat du nutriment digestible total a été significativement (P<0.05) plus élevé en T2 (92.90 %) que le T1 (84.99%) qui était le régime de contrôle. La digestibilité des fibres brutes enregistrée en T2 (63.48%) et T1 (61.09 %) est plus élevé que T5 (43.00 %), la digestibilité de l'extrait d'éther de T1 (96.42 %) est plus élevé que les autres groupes ayant le plus faible taux de T4 (95.25 %). Il y avait une digestibilité déprimante des cendres en T5 (68.30 %), inférieure à celle des autres groupes ayant le taux le plus élevé en T1 (82.59 %). L'étude a donc conclu que les agriculteurs peuvent remplacer les aals de blé par 25 % de croûte de pastèque dans le régime de démarrage des poulets à griller sans aucun effet délétère dans la performance de croissance et la digestibilité des nutriments.

An experiment was conducted to evaluate the effect of substituting different levels of sun-dried Irish potato peel meal (SPPM) for maize in diets of broiler chickens. Five diets in which SPPM was replaced with 0 (0SPPM), 25 (25SPPM), 50 (50SPPM), 75 (75SPPM) and 100% (100SPPM) of maize in starter and finisher diets for a 8 week period using broiler chickens were examined. A total of 300 two weeks old broilers chicks Anak 2000 were randomly allotted to five experimental diets with six pen per treatment and 10 birds chicks per pen. Body weight and feed intake of broilers, and feed conversion ratio were determined at the beginning and 56th day of the experiment respectively. On day 56, four broilers from each pen were selected and slaughtered to determine some carcass characteristics and serum biochemistry. The result of growth performance showed that 100SPPM decreased daily weight gain of chickens when compared to other SPPM levels (P
