A 23 factorial design was used to examine the effects of the following treatments on the productivity of steers fed in yards on an all-sorghum grain ration : nil vs. 70 mg chlortetracycline head-1 day-1; nil vs. 3 per cent dried molasses distillers solubles; nil vs. 36 mg implant of Zeranol. An additional treatment eompared zinc bacitracin with chlortetracycline. Eighteen groups each of five Hereford steers of a mean initial shrunk liveweight of 273.5 � SE 1.00 kg were used. They were slaughtered at a mean final shrunk liveweight of 399.8 � 2.97 kg. Mean results were: liveweight gain 1 .17 kg day-1, carcase weight gain 0.69 kg day-1, DM feed intake 6.91 kg day-1, feed conversion ratio 6.0. Feeding chlortetracycline resulted in increased carcase weight gain, an improved feed conversion ratio and a reduction in the number of liver abscesses. Regarding productivity, zinc bacitracin was not significantly different from chlortetracycline but it had no effect on reducing liver abscesses. Adding dried molasses distillers solubles caused a decrease in live- and carcase weight gain and an inferior feed conversion ratio. The anabolic implant Zeranol resulted in increased live- and carcase weight gain, increased DM feed intake but no significant differences in feed conversion ratio. The treatments had no effect on eye muscle area or muscle percentage of the carcases. Dried molasses distillers solubles was associated with a lower fat percentage (1 9.5 vs. 20.8 � 0.43; P <0.05). The rationsbsed resulted in an acetic to propionic ratio in ruminal fluid of 0.44 :1. There were no interactions and the usefulness of chlortetracycline and Zeranol and the poorer production using molasses distillers solubles in all-grain diets are discussed.

Abstract This study was conducted to examine the growth performance and expression patterns of growth hormone gene and insulin-like growth factor in metabolic tissues of pigs fed different unconventional feed sources. A total of 45 growing pigs were randomly assigned to 5 dietary treatments at 9 animals per treatment and 3 animals per replicate. Treatment one (T1) comprise of whole maize (WM) which served as the control, T2: brewers dried grain (BDG), T3: cassava peel meal (CPM), T4: plantain peel meal (PPM) and T5: corn husk meal (CHM) at 35% inclusion in the diet. Data collected and analyzed includes; initial body weight (IBW), final body weight (FBW), average daily feed intake (ADFI), average daily weight gain (ADG), feed conversion ratio (FCR) and feed efficiency (FE). At the end of the feeding trial, three animals per treatment (one animal per replicate) were slaughtered; the duodenum and liver were collected and stored using RNALater prior to RNA extraction. Real-time qPCR was performed in 40cycles using the PowerUp SYBR Green reagent and analysed using the Delta-Delta Ct method. All data were subjected to analysis of variance in a completely randomized design. The results showed that the treatment diets had effect on growth performance with significant differences (P &lt; 0.05) observed for average final weight, average total weight gain, average daily feed intake, feed conversion ratio and feed efficiency while the initial weight were not significantly different (P &gt; 0.05). IGF-2 was differentially expressed in the liver and duodenum across treatments while significant differences were not observed in the expression pattern of the growth hormone gene in both tissues. This study showed promise for the use of unconventional feeding stuffs in pig feeding and reveals that genes influencing performance characters are differentially expressed in relation to the source of unconventional feeds used in compounding pig diet.

Eighty black Nera cockerel chicks were randomly alloted to four dietarey treatmants containing 0, 10, 20 and 30% kolanut husk meal (KHM) for twelve weeks. Significant differences (P<0.05) in feed intake, weight gain and feed conversion ratio were observed. Dietary inclusion of KHM depressed (P<0.05) growth rate feed conversion ratio and nutrition uilization of cockerels birds. There were linear reduction (P>0.05) in nitrogen retention and apparent crude fibre digestibility (ACFD) of  cockerels birds at each incremental KHM dietary levels. This indicated that KHM could be effeciently utilized by cockerels up to 205 dietary level above which the depression in growth rate occurs.

This study was carried out to evaluate the impact of raw and cooked wild cocoyam (Caladium bicolor) on the performance of broiler chicks. Wild cocoyam corms were divided into two batches. One batch was ground raw and the other batch was cooked before grinding. Wild cocoyam meals so prepared were used to formulate 5 broiler starter diets at dietary inclusion levels of 0, 10 and 20% raw and cooked wild cocoyam respectively. 180 7-day-old Anak broiler chicks were randomly allotted to the five treatment diets in a Completely Randomized Design (CRD) and each group was further subdivided into three replicates of 12 birds. Measurements recorded included weight gain, feed intake, feed conversion and protein efficiency ratios and economics of production. Results shows significant (p<0.05) improvement in feed intake, weight gain, feed conversion ratio and PER of birds fed cooked wild cocoyam meals. Marked (p<0.05) reduction was however, obtained in feed intake and feed conversion ratio of birds fed raw wild cocoyam diets. There was no significant (p>0.05) difference between birds fed maize-based (control) and cooked wild cocoyam diets. Results of this experiment indicated that cooking improved the nutritive value of wild cocoyam since birds fed cooked wild cocoyam diets produced best results than those fed raw wild cocoyam meal and that starter broilers could tolerate up to 20% dietary inclusion level of cooked wild cocoyam without any deleterious effect. Economics of production showed that cooked wild cocoyam diets were more profitable as regards the cost of feed per kg weight gain (N) and thus cost savings (%).

Forty crossbred weaner rabbits were used in a factorial experiment involving three levels (15, 30 and 45%) of groundnut haulms(GHM) and two feeding systems (separate and mixed). Ratios of concentrate to groundnut haulms or groundnut haulmsmeal were: 1) 85% concentrate plus 15% GHM, 2) 70% concentrate plus 30% GHM and 3) 55% concentrate plus 45% GHM. For separate feeding system, concentrate and groundnut haulms were offered in separate feeders while for mixed feeding system, groundnut haulms meal was incorporated into the concentrate as complete diets. The control rabbits were placed on concentrate alone. Total feed offered was 100g/rabbit/day. Final weight, feed intake and total weight gain increased quadratically with increase in level of groundnut forage. Weight gain and feed conversion ratio were not affected by level of groundnut forage. Feed cost and cost/kg gain decreased with increase in groundnut haulms level. Savings/kg gain increased with increase in level of groundnut haulms from ₦7.9 to ₦107.6. Feeding groundnut haulms separately or mixed increased daily feed intake of rabbits than sole concentrate. ADG was higher for separate feeding than mixed and sole concentrate. Feed cost was significantly higher for sole concentrate than separate and mixed feeding. Savings/kg gain was ₦450 - ₦300 for separate and mixed feeding compared with sole concentrate. Feed intake was higher for separate at 15 and 45% GHM, while for 30% GHM, mixed feeding had higher intake than separate system. ADG was higher for separate than mixed feeding for all levels of groundnut forage. Feed conversion ratio was similar for separate and mixed feeding system irrespective of groundnut haulms level. Feed cost was lower for separate feeding system at all GHM levels except for 30% GHM level where it was higher for mixed than separate feeding. Feed cost/kg gain was higher for mixed feeding at 15 and 45% GH and lowest for separate at 45% GHM. It is concluded that rabbits can be offered up to 45% GHM while, separate feeding was better than mixed feeding.

An experiment was designed and carried out to assess the growth performance and feed utilization (weight gain, feed conversion ratio, protein efficiency ratio, specific growth rate, feed intake and survival) of Clarias gariepinus fingerlings fed graded levels of toasted Leucaena leucocephala seed meal based diets with the aim of establishing the best inclusion level of Leucaena seed meal. One hundred and eight (108) fingerlings with an initial mean weight of 2.10g were allotted at random to six treatments in triplicate groups with each treatment tank having six fingerlings and were fed with isocaloric and isonitrogenous diets containing 40% crude protein (CP). The toasted seed meal was used to replace soybean meal in the diets in the following proportions: diets I (0%), diets II (10%), diets III (20%), diets IV (30%), diets V (40%) and diets VI (50%). At the end of the feeding trials that lasted for 6 weeks, the mean weight gains of fish, relative weight gain, specific growth rate, feed intake, feed conversion ratio and protein efficiency was highest in treatment I while mean weight gain of fish, relative weight gain, specific growth rate and feed conversion ratio was lowest in treatment V. Feed intake was lowest in treatment VI and protein efficiency was lowest in treatment II. Survival among treatments slightly varied significantly but was not as a result of the feed consumed. At the end of the experiment, the recommended inclusion level of Leucaena seed meal was 20%.

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.

Considering the inherent attributes of tannia cocoyam (Xanthosoma sagitifolium) its appropriate utilization may enhance performance of starter broiler chicks. This study was therefore carried out to determine the dietary evaluation of starter broiler chicks fed cooked cocoyam tuber meal as energy source in place of maize. The cooked cocoyam tuber meal was used to replace maize at various levels of 25%, 50%, 75% and 100% respectively for diets 2, 3, 4 and 5 to determine the best replacement level that would give optimal performance in starter broiler chicks' diets. Result of the proximate composition of cooked cocoyam tuber meal showed that it contained 13.11% moisture, 2.60% ash, 1.85% ether extract, 3.90% crude protein, 9.45% crude fibre, 70.13% nitrogen free extract and 3004.37 Kcal/kgME. 150 day old Anak broiler chicks were used for the experiment. They were divided into 5 treatment groups of 30 broiler chicks each. Each treatment group was subdivided into 3 replicates of 10 broiler chicks each and kept in deep litter. Each starter diet was fed to a group of 30 starter broilers for 4 weeks using completely randomized design. They were given feed and water adlibitum. Parameters measured include initial body weight, final body weight, body weight gain, feed intake, feed conversion ratio and economics of production. In the starter broiler feeding trial, the starter broilers on 25% cooked cocoyam meal compared favourably with the control (P> 0.05) in terms of feed intake, body weight gain and feed conversion ratio and significantly (P > 0.05) performed between than those on 100% CCYM. The cost of production (N/Kg broiler) was however cheapest for diet 2 (25% CCYM) N395 versus control diet (N494.28). It was therefore concluded that cooked cocoyam tuber meal (Xanthosoma sagitifolium) could be used in the diets of starter broiler chicks' up to 25% without affecting the body weight gain, feed intake and feed conversion ratio as indicated in this study.

The effect of dietary treatments on growth performance, haematological and biochemical indices of finisher broilers as well as economics of broiler production were determined in this experiment. Four broiler finisher diets were formulated with different inclusion levels of fermented cassava flour/blood mixture code-named “cassablood”. The control diet (T1) contained 0% cassablood, while diets 2, 3 and 4 contained 20%, 25% and 30%  cassablood respectively. 120 four weeks old Anak broiler chicken were randomly allocated the 4 diets with 30 birds per treatment replicated 3 times with ten 10 broilers per replicate in a completely randomized design (CRD).Treatment effects on final body weight, final weight gain, feed intake and feed conversion ratio were significant (P<0.05). Birds fed cassabloodbased diets compared favourably with the control diet. 20% cassablood inclusion performed equally with the control diet in feed intake, body weight gain and feed conversion ratio. All dietary groups also showed no significant differences (P>0.05) in most haematological and serum biochemical indices of broilers except in cholesterol, glucose and triglyceride contents which differed (P<0.05) significantly Similarly, chicken on 20% and 25% inclusion levels produced significantly (P < 0.05) higher economic gains in terms of feed cost per kilogram of broiler among all the treatments. Therefore, 20 - 25% cassablood dietary inclusion level was recommended in broiler diet for production and profit maximization.

An experiment was conduct in order to investigate the effects of feed restriction level and duration and dietary coenzyme Q10 level on growth performance, organ characteristics and plasma lipoproteins. A factorial arangment based on a completely randomized design was performed using two levels of feed restriction (10 and 20% less than the standard Ross strain 308 guidelines), two levels of restriction duration (7 and 14 days) and three levels of coenzyme Q10 (0, 20 and 40 mg/kg feed). The results of the experiment showed that restriction intensity had significant effect on feed intake in first, second and sixth weeks of age (P<0.05), body weight gain in second and sixth weeks of age (P<0.05), and feed conversion ratio in first week of age (P<0.05). Restriction duration had significant effect on feed intake in third week of age (P<0.05), and feed conversion ratio in third and sixth weeks of age (P<0.05). Coenzyme Q level had significant effect on feed intake in first and sixth weeks of age (P<0.05), body weight gain in second, fifth and sixth weeks of age (P<0.05), and feed conversion ratio in second and sixth weeks of age (P<0.05).  In conclusion, considering the positive effects of feed restriction and coenzyme Q10 on broiler yield, the simaltaneous use of feed restriction strategy and dietary coenzyme Q10 can be considered as a management program in order to improvement of broiler productivity.
