A concise and factual abstract This study aims to find out the influence of the use of banana peels in pellet rations to improve the performance of local male rabbits (Lepus nigricollis). The study used 20 local male rabbits that were maintained from 5 to 12 weeks old. The study used Randomized Group Design with 4 treatments and 5 repeats. The treatments in this study are: Rabbit feed that did not contain banana peels (R0), Rabbit feed that contained 5% banana peels (R1), Rabbit feed that contained 10% banana peel (R2), and Rabbit feed that contained 15% banana peel (R3). The results showed no noticeable difference (P>0.05) in the treatment of rations against the ingenuity of dry matter digestibility, energy digestibility, protein digestibility, protein consumption, consumption of dry materials, and Feed Conversion Ratio (FCR). Rabbits who get R1 ration treatment produce the final weight and the weight gain was significantly different (P<0.05) to R0 and R3 treatment, and not significantly different (P>0.05) on R2 treatment. R1 ration consumption is the highest (P<0.05) compared to R0, R2, and R3 treatments. The effect of ration treatment on carcass variables shows results significantly different (P<0.05).

This study was carried out at the Abu Ghraib sheep and goat breeding station to study the effect of adding different levels of zinc (0, 15, 20 and 25 mg/kg. DM) which type of radians: concentrate diets 25% or alfalfa hay 75% in the performance of local goat females and some carcass characteristics of goat females. The animals were divided into four groups (T1) fed free of additives and T2 fed 15 mg zinc/kg.DM and T3 and T4 groups fed 20 and 25 mg/kg.DM of zinc. The results showed no significant effect of adding zinc to the diet on the total feed intake for all nutrients except the dry matter intake (g/ kg) that were increasing significant (P˂0.01) For all groups of adding zinc, Also the results showed that there were increase significant (P˂0.01) in some of the studied traits (total and daily weight and feed conversion ratio as well as the final weight of local goat females). The results also showed increase significant (P˂0.01) in some of the carcass characteristics (slaughter weight, empty body weight, warm carcass weight and the percentage of conversion based on body weight) compared with the T1 group.

As daily methane production (DMP; g CH4/day) is strongly correlated with dry matter intake (DMI), the breeding of cattle that require less feed to achieve a desired rate of average daily gain (ADG) by selection for a low residual feed intake (RFI) can be expected to reduce DMP and also emission intensity (EI; g CH4/kg ADG). An experiment was conducted to compare DMP and EI of Angus cattle genetically divergent for RFI and 400-day weight (400dWT). In a 6-week grazing study, 64 yearling-age cattle (30 steers, 34 heifers) were grazed on temperate pastures, with heifers and steers grazing separate paddocks. Liveweight (LW) was monitored weekly and DMP of individual cattle was measured by a GreenFeed emission monitoring unit in each paddock. Thirty-nine of the possible 64 animals had emission data recorded for 15 or more days, and only data for these animals were analysed. For these cattle, regression against their mid-parent estimated breeding value (EBV) for post-weaning RFI (RFI-EBV) showed that a lower RFI-EBV was associated with higher LW at the start of experiment. Predicted dry matter intake (pDMI), predicted DMP (pDMP) and measured DMP (mDMP) were all negatively correlated with RFI-EBV (P < 0.05), whereas ADG, EI, predicted CH4 yield (pMY; g CH4/kg DMI) were not correlated with RFI-EBV (P > 0.1). Daily CH4 production was positively correlated with animal LW and ADG (P < 0.05). The associations between ADG and its dependent traits EI and pMY and predicted feed conversion ratio (kg pDMI/kg ADG) were strongly negative (r = –0.82, –0.57 and –0.85, P < 0.001) implying that faster daily growth by cattle was accompanied by lower EI, MY and feed conversion ratio. These results show that cattle genetically divergent for RFI do not necessarily differ in ADG, EI or pMY on pasture and that, if heavier, cattle with lower RFI-EBV can actually have higher DMP while grazing moderate quality pastures.

SUMMARYForty-eight pigs were used to compare the feeding value of barley which had been stored dry, and then hammer-milled, with that of barley stored moist, either anaerobically or treated with 1·3% propionic acid, and then rolled. The pigs were fed from 30 kg live weight for a period of 11 weeks and during this period all consumed the same allowance of dry matter. The growth rate and feed conversion ratio of the pigs given the rolled moist barley were significantly poorer than those of others given dry milled or acid treated rolled barley. There were no treatment differences in carcass attributes.Microbiological counts made throughout the experiment showed that there was no significant fungal or bacterial development on the acid treated barley. Similar numbers of bacteria were present on the dry barley as on the moist, but the fungal count for the moist grain was always at least 500 times higher than that of the corresponding dry sample. The dominant organisms were identified.In a further experiment the apparent digestibility of dry matter and nitrogen of diets containing dry, moist or propionic acid treated barley, processed either by milling or rolling, were determined. The highest values were obtained for dry barley. Acid treated moist barley had lower values than moist barley. The method of processing did not affect the apparent digestibility of the dry matter, but that of the N was significantly lower for the rolled barleys.

Abstract Year-round availability of feed is a major concern for dairy farmers in many parts of the tropics. Silage making is a reliable means of providing feed for dairy cattle during periods of forage scarcity. In this study, Elephant grass (EG) (Pennisetum purpureum) was ensiled with cassava peel (CSP) at 0, 10, 30 and 50% levels of inclusion on a wet basis. At 21, 42 and 63 days of ensiling, silage samples were taken for chemical analysis and the remaining materials were fed to four lactating Sokoto Gudali cows for a period of 84 days using a Latin square design. Dry matter (DM) content of silage mixtures increased from 18.22 to 28.70% as level of CSP in the silage mixture increased while crude protein (7.33 to 6.08%) and crude fibre (32.80 to 23.95%) decreased. Dry matter intake of cows, milk yield and feed conversion ratio (FCR) varied (P < 0.05) with inclusion of cassava peel in the silage mixtures. Dry matter intake of cows increased from 2.56 to 3.84% of body weight (BW) and milk yield from 2.90 to 6.70 kg/d as proportion of CSP in the grass silage increased. Feed conversion ratio of cows ranged from 2.08 to 3.23 and improved with inclusion of CSP in the silage. These results show that addition of cassava peel to Elephant grass silage improved intake and milk production in Sokoto Gudali cows fed Elephant grass silage.

Canola meal (CM) is a locally produced protein source that may be less expensive than soybean meal (SBM). This study evaluated the effects of replacing 0%, 25%, 50%, 75%, and 100% SBM with CM in diets for slaughter ostriches. The CM was added at the expense of SBM and other concentrates, with minor changes in other ingredients. Birds (n = 15 per treatment) were reared from 77 to 337 days old on the trial diets, which were supplied ad libitum for starter, grower, and finisher phases. Bodyweights and feed intake were measured during these phases. No differences (P >0.05) were found between treatments for live weight at the end of each phase, dry matter intake (DMI), average daily gain (ADG) and feed conversion ratio (FCR) over all the growth phases. Although no differences were observed in live weight at the end of each phase, the birds reared on the diet with 50% CM were heaviest at slaughter, and birds reared with 100% CM were lightest (P <0.05). Differences (P <0.05) between diets were observed for the weight at slaughter, weights of the liver and thyroid glands and the pH of the cold carcass. However, no differences (P >0.05) were observed between diets for fat pad weight, dressing percentage, and weights of thighs and Muscularis gastrocnemius. The results indicate that CM could replace SBM in the diets of slaughter ostriches without affecting production traits and slaughter yields.Keywords: alternative protein, average daily gain, canola, dry matter intake, feed conversion ratio, growth, ostrich nutrition, production

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.

Means of cutting down cost of feed resources in order to bridge the wide gap between demand and supply of animal protein in livestock production is a great concern in the poultry industry. This study was conducted to investigate the effect of feeding diets containing soaked and fermented Baobab seed meal (BSM) on the growth performance of broiler starter chicks. A total of 150, one-day old chicks were randomly distributed into five treatment groups. Treatments were replicated three times with 10 chicks per replicate in a completely randomized design (CRD). The dietary groups were designated as T1 for control (0 % BSM), T2 (7.5 % SBSM), T3 (15.0% SBSM), T4 (22.5% FBSM) and T5 (30 % FBSM). Parameters monitored include final weight, weight gain, feed intake, feed conversion ratio, feed cost per kg gain (N) and mortality (%) The experiment lasted for 4 weeks. The results showed that the dietary treatments had significant (P<0.05) effect on all the parameters measured. Final weight and total weight gain were similar and significantly (P<0.05) higher in birds fed diets T2 and T4 when compared to other dietary treatments. However, birds in T5 group had the least significant (P<0.05) values 366.67 and 217.34 g/bird respectively. Daily weight gain (7.76 g/bird/day), total and daily feed intake (873.33 g and 31.19 g/bird/day) of birds followed similar trend and were significantly (P<0.05) lower in T5 group compared to other treatments. Feed conversion ratio of birds fed diet T5 had significantly (P<0.05) higher value (4.29) when compared to those in other treatment groups. Feed cost per kg gain (N) was significantly (P<0.05) lower and similar in birds fed T2, T3 and T4 when compared to values obtained in the control group (N253.27) and T5 (N 327.52). Mortality (%) only occurred in birds fed T5. It was therefore concluded that inclusion of 22.5% fermented baobab seed meal in broiler diets improved performance and had no negative effect on the health status of birds.     Des moyens de réduire le coût des ressources alimentaires afin de combler le defi posé à cause de la demande et l'approvisionnement en protéines animales dans la production animale est une grande préoccupation dans l'industrie avicole. Cette étude a été menée pour étudier l'effet des regimes alimentaires contenant de la farine de graines de baobab trempée et fermentée (le 'BSM') sur les performances de croissance des poussins de départ. Un total de 150 poussins âgés d'un jour ont été répartis au hasard en cinq groupes de traitement. Les traitements ont été répliqués trois fois avec 10 poussins par réplique dans une conception complètement randomisée (le 'CRD'). Les groupes diététiques ont été désignés comme T1 pour le contrôle (0% BSM), T2 (7,5% SBSM), T3 (15,0% SBSM), T4 (22,5% FBSM) et T5 (30% FBSM). Les paramètres surveillés comprennent le poids final, le gain de poids, la prise alimentaire, le taux de conversion alimentaire, le coût de l'alimentation par kg de gain (N) et la mortalité (%). L'expérience a duré 4 semaines. Les résultats ont montré que les traitements diététiques avaient un effet significatif (P <0,05) sur tous les paramètres mesurés. Le poids final et le gain de poids total étaient similaires et significativement (P<0,05) plus élevés chez les oiseaux nourris avec les régimes T2 et T4 par rapport aux autres traitements diététiques. Cependant, les oiseaux du groupe T5 avaient les valeurs les moins significatives (P <0,05) 366,67 et 217,34 g / oiseau respectivement. Le gain de poids quotidien (7,76 g / oiseau / jour), l'apport alimentaire total et quotidien (873,33 g et 31,19 g / oiseau / jour) des oiseaux ont suivi une tendance similaire et étaient significativement (P<0,05) inférieurs dans le groupe T5 par rapport aux autres traitements. Le rapport de conversion alimentaire des oiseaux nourris au régime alimentaire T5 avait une valeur significativement plus élevée (P <0,05) (4,29) par rapport à ceux des autres groupes de traitement. Le coût de l'alimentation par kg de gain (N) était significativement (P <0,05) plus faible et similaire chez les oiseaux nourris T2, T3 et T4 par rapport aux valeurs obtenues dans le groupe témoin (N253,27) et T5 (N 327,52). La mortalité (%) n'est survenue que chez les oiseaux nourris au T5. Il a donc été conclu que l'inclusion de farine de graines de baobab fermentée à 22,5% dans les régimes alimentaires des poulets de chair améliorait les performances et n'avait aucun effet négatif sur l'état de santé des oiseaux.

A total of two-hundred-and-forty day old broiler chicks were used to study the response of broiler birds to diets containing graded levels of tiger nut residue (TNR) as a replacement for maize. The diets consisted of 0, 10, 20 and 30% of TNR as a replacement for maize as T1 (control), T2, T3 and T4 respectively. The birds were allotted to four dietary treatments of 4 replicates each containing 60 and 15 birds respectively in a completely randomized design. The data obtained from the experiment were subjected to one - way analysis of variance. The results showed that average weight gain (AWG) and final weight gain (FWG) were high for birds fed 10% TNR and increased numerically than the 0, 20 and 30% groups at the starter phase. In the finisher phase the average weight gain (AWG) and final weight gain (FWG) followed the same trend. Feed intake was not significantly affected by the diet at the starter and finisher phases. In the starter phase the T1 (control) recorded the best and the lowest feed conversion ratio but in the finisher phase, the best feed conversion ratio was observed in T2. The TNR inclusion had no significant (p˃0.05) effect on live weight, dressed weight, dressing percentage, cut-parts and organs of the birds. The haematological parameters were not significantly (p˃0.05) affected by the diets. All the biochemical parameters determined; serum protein, albumin, globulin, urea, creatinine, ALT, AST, cholesterol and triglyceride were not significantly (p˃0.05) affected by the treatment diet. It was concluded that tiger nut residue (TNR) as a replacement for maize at a 30% level of inclusion did not cause any deleterious effects on the performance, carcass and blood profiles of broilers

Consequences of low (mean 28.0 kg, n = 77) and high (mean 38.4 kg, n = 77) birthweight followed by slow (mean 548 g/day, n = 75) or rapid (mean 859 g/day, n = 79) growth to weaning for feedlot growth, intake and efficiency from 26 to 30 months of age were determined in Wagyu × Hereford (n = 81) and Piedmontese × Hereford (n = 73) cattle. Cattle were selected for study based on birthweight and preweaning growth rate, from multi-modal distributions achieved by imposition of low or high maternal nutrition during pregnancy and lactation, with the objective of achieving as close as possible to a 30% difference in birthweight and a 2-fold difference in preweaning growth rate between progeny groups. High birthweight cattle entered the intake test 57 kg heavier, grew 100 g/day more rapidly, and ate 1.0 kg dry matter /day more than the low birthweight cattle. The high birthweight cattle tended to have a higher feed conversion ratio than low birthweight cattle, but net feed intake did not differ due to birthweight group. Cattle grown rapidly to weaning entered the intake test 29 kg heavier, grew at an equivalent rate, and ate 0.7 kg dry matter/day more than the cattle grown slowly to weaning. No differences in feed conversion ratio or net feed intake were observed between the preweaning groups. When assessed at the same liveweight, differences in dry matter intake and/or feed conversion ratio due to birthweight or preweaning growth were no longer apparent. Interactions between prenatal and preweaning growth, or between sire genotype and early-life growth, were not evident for feedlot growth, intake or efficiency. It is concluded that severely restricted growth during prenatal life or from birth to weaning results in cattle that are smaller and consume less feed at the same age as their well grown counterparts; however, long-term effects of growth during early life on efficiency of utilisation of feed are not evident.
