The growth response and feed utilization of Clarias gariepinus fed with diet containing different level of dietary synthetic methionine was investigated to determine the effect of diet on their growth rate and its utilization by fish. (108) fingerlings of Calrias gariepinus (2.1+0.5g) obtained from a private fish farm in Benin City were stocked in eighteen (18) 25L plastic tank. 6 diet (40%) crude protein consisting of a control (0% methionine supplementation) and five DIT other diet (3.2%, 4.23%, 7.30%, 8.70% and 9.79% synthetic methionine supplementation) were compounded and fed to the fish till satiation. Each diet was fed to the fish twice daily (9.00hrs and 17.00hrs). Data on the weight gain and feed consumed were taken on weekly basis. There was no significant difference in term of relative weight gain (RWG), specific growth rate (SGR), total weight gain (TWG) and weekly weight gain (WWG). The control with (0% methionine) showed a higher weight gain with diet 5 (8.76% methionine) having a lower weight gain. However, the feed intake (FI) was significantly different (P<0.005) with the control midway the highest feed intake but diet 2 (4.25%) with a step downward showed lowest feed intake. The protein efficiency ratio (per) value were significantly different with diet 1 having the highest value which was different from all other which with diet 4 having a lowest per. In terms of survival there was significant difference (P<0.05) with diet 3(0% methionine). Supplementation has the highest and a reduced survival at diet 2 synthetic methionine. In this study synthetic methionine had not been sufficiently utilized by Clarias gariepinus fingerling since the control did perform better than those supplemented with various level of methionine.

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%.

This study was carried out to investigate the performance of broilers fed graded levels of Dry Distilled Cassava with Soluble (DDCS). In a 28-day trial, one hundred and forty-four (144), 5-week old, un-sexed Arbor acre strain broiler chicks (average weight of 1.09±0.02 kg) were randomly allocated to four dietary treatments of wheat offal (WO) and DDCS (12% WO + 0% DDCS = 0% DDCS; 8% WO + 4% DDCS = 4% DDCS; 4% WO + 8% DDCS = 8% DDCS and 0% WO + 12% DDCS = 12% DDCS) in completely randomized design. Each treatment had 2 replicates of 18 birds each. Dry matter feed intake (FI g/day), daily weight gain (g/day) and total weight gain (kg) decreases with increase in the levels of DDCS, while the feed conversion ratio (FCR) increases with increase in levels of DDCS, respectively. However, there was no significant (P>0.05) differences in the carcass evaluation measured. It was concluded that DDCS could replace wheat offal in the diets of broilers up to 8% without significant difference in growth and feed intake without detrimental effects on carcass quality of the birds.     Cette étude a été réalisée pour étudier la performance des poulets de chair nourris à des niveaux échelonnés de manioc distillé sec avec soluble (le 'DDCS'). Dans un essai de 28 jours, cent quarante-quatre (144) poussins de chair de la souche Arbor acre non sexés de 5 semaines (poids moyen de 1.09 ± 0.02 kg) ont été répartis au hasard dans quatre traitements diététiques d'abats de blé (WO) et DDCS (12% WO + 0% DDCS = 0% DDCS ; 8% WO + 4% DDCS = 4% DDCS ; 4% WO + 8% DDCS = 8% DDCS et 0% WO + 12% DDCS = 12 % DDCS) dans une conception complètement aléatoire. Chaque traitement comportait 2 répétitions de 18 oiseaux chacun. L'apport alimentaire en matière sèche (FI g / jour), le gain de poids quotidien (g / jour) et le gain de poids total (kg) diminuent avec l'augmentation des niveaux de DDCS, tandis que le taux de conversion alimentaire (FCR) augmente avec l'augmentation des niveaux de DDCS, respectivement. Cependant, il n'y avait aucune différence significative (P> 0.05) dans l'évaluation de la carcasse mesurée. Il a été conclu que le DDCS pouvait remplacer les abats de blé dans l'alimentation des poulets de chair jusqu'à 8% sans différence significative de croissance et de consommation alimentaire sans effets néfastes sur la qualité de la carcasse des oiseaux.

The effect of forage to concentrate ratios on the performance of weaner rabbits was investigated using twenty (20) weaner rabbits. They were randomly assigned to five treatment diets/with two replicates of two (2) rabbits per pen in a completely randomized design CRD). The experiment lasted for 56 days. Ti = forage 80%: concentrate 20%, T2 = forage 60%. concentrate 40%, T3 = forage 40%: concentrate 60%, T4 = forage 20%: concentrate 80% and T5 = forage 50%: concentrate 50% served as the control. Data were collected for feed intake, weight gain, carcass quality and the economics of the diet. The growth performance result was significantly different (p<0.05) for all the parameters considered except for total feed intake. Treatment 3 (T3) had the highest value for final weight (1423.0 g), total weight gain (925.5g) and daily weight gain (16.52 g), with the least feed conversion ratio of (2.58) among others. The cut parts results showed that there was significant difference (p<0.05) for all the parameters considered. 73 also had the highest value for the prime parts. The organ weights results did not follow any specific pattern that could be attributed to the effect of the test ingredients. The economics /gross margin showed that T3 was favoured among others A 731.38, N929.18, N1045.78, N828.81, N825.39),T3 (forage40%: concentrate 60%) was therefore recommended.

Sugarcane peels (SCP) is available in large quantities all year round especially in sugar industries where they are discarded as waste product. It contains high amount of carbohydrate and minerals which could be fed to animals especially when properly processed and supplemented with exogenous enzyme to aid the animal digest it. Fifty - four weaned 4-5 weeks old crosses of New Zealand white x Chinchilla male rabbits were utilized to evaluate the effect of feeding sugarcane peel meal-based diets supplemented with quantum blue® on the growth performance parameters (initial weight, final weight, weight gain, feed intake, FCR and feed cost per weight gain) and nutrient digestibility by weaner rabbits. Six diets were formulated to be iso-nitrogenous (18% crude protein) and isocaloric (2700kcal/kg, ME) with two levels of inclusion of sugarcane peel meal (SCPM) (low and high) and three levels of enzyme supplementation (0, 150 and 250 PPM) giving a 2x3 factorial arrangement fitted into Completely Randomized Design. The rabbits were weighed and allotted to the treatments at the rate of 3 rabbits per replicate and each treatment was replicated 3 times. Feeds were weighed and served to the animals individually and water was provided ad-libitum. Growth parameters and nutrient digestibility data were generated and evaluated. The results of the effect of enzyme on growth performance of weaner rabbits showed that average total weight gain significantly (P<0.05) improved as rabbits fed the 200PPM enzyme supplemented diets had the best value of 511.67g/rabbit. However, rabbits fed the 100PPM performed (410.83g/rabbit) the same as those fed the 200PPM. Similarly, rabbits fed the 200PPM enzyme supplemented diets gained more (P<0.05) daily weight of 10.40 g/rabbit/day followed by those fed the 100PPM (8.32 g/rabbit/day). The result of the effect of high SCPM showed that feed intake significantly (P<0.05) increased from 47.37 g/rabbit/day to 59.82 g/rabbit/day as the level of SCPM increased in the diets; rabbits fed the high SCPM had higher total weight gain of 484.44 g/rabbit as compared to those of low SCPM (362.78 g/rabbit). The interactive effects of SCPM and enzyme on growth performance of weaner rabbits showed that final live weight, feed intake and total weight gain were significantly (P<0.05) improved as the levels of SCPM and enzyme increased in the diets. In view of the findings, rabbit farmers can supplement 32% of SCPM in the diets of  weaner rabbit with 200PPM of quantum blue® without negatively affecting the growth rate and suppressing the digestibility of nutrients by weaner rabbits.

This study examined the replacement of soyabean meal (SBM) with Lablab bean meal (LBM) in the practical diets of Clariid catfish (Heteroclarias). Five Iso-nitrogenous diets of 40%CP containing varying levels of LBM were incorporated as a non-conventional feedstuff at D1(10% LBM); D2(20%LBM); D3(30%LBM); D4(40%LBM) and D5(50% LBM) as a replacement for soyabean meal. Seventy-five Heteroclarias fingerlings with an initial mean weight of 1.46±0.01 g were stocked randomly to five treatments in triplicate groups and were fed to satiation twice daily for a period of 70 days. At the end of the 70days experimental period, all growth parameters decreased across all diets from D1 to D5. D1(10% LBM) had the best growth rate as it recorded the highest value in terms  of weight gain (1.25); feed intake (2.34); feed conversion ratio (1.86); relative weight gain (4.86) and specific Growth rate of (1.33) while D5 recorded the least values across all parameters. D1 was not significantly different (P>0.05) from D­2 in all growth parameters listed above but D1 and D2 were significantly different (P<0.05) from D3, D4 and D5. Therefore, Lablab bean meal can replace soyabean meal totally but will be best at 10% replacement in diets for Hetero clarias without compromising the growth and carcass composition. Further research should be carried out to test lablab meal on pure Heterobranchus bidorsalis fingerlings.

The use of Silkworm (Anaphe infracta) pupae as a protein source was investigated for its ability to replace fishmeal in the diet of Clarias gariepinus, African cat fish. Five dried diets formulated at 40% crude protein were fed to fingerlings of an average initial weight of 14.33g at 0 (control diet), 25, 50, 75 and 100% inclusion levels of silk worm meal. The experiment was conducted for 84 days were measured. Mean weight gain (MWG), specific growth rate (SGR), feed conversion ratio (FCR). The five inclusion levels of silk worm pupae supported the growth of Clarias gariepinus fingerlings, the growth and feed utilization were favoured by high inclusion level of silk worm meal. Significant differences (p<0.05) were observed among the treatments, although there were no significant differences (p>0.05) in the growth parameters between 50% and 75% inclusion levels. The 100% silk worm pupae meal inclusion gave the best final mean weight gain of 10.29g specific growth rate of 0.93%, feed conversion ratio of 2.18 and protein efficiency ratio (PER) of 0.012. The carcass protein and lipid contents increased compared to the levels of both at the beginning of the experiment. Even though, there were no significant differences (p>0.05) among proximate composition of the fish groups fed 25, 50 and 75%. The results showed that diet consists of 100% silk worm meal could be used as a complete replacement for fish meal in the diet formulation for Clarias gariepinus fingerlings.

Fish meal is generally expended as the foremost protein supply in the fish diet. The rising cost of this component inflicted the aquaculture industry to seek a substitute in lessening the pellet cost. Thus, fish waste was tested in this study to investigate its viability. An experiment was performed to study the effects of fish waste and carcass on the growth performance of Nile tilapia fry. Solid fish waste of three different common species available in Mukah’s wet market was formulated into an artificial diet. The diet was formulated into three treatments consist of three protein levels (40%, 45% and 50%) with 4000 kcal/kg energy. A controlled group was fed with a commercial pellet consisting of 45% protein level. Fish were fed at 4% of body weight twice daily for 45 days. Fry reared in a controlled group was discovered highest weight gain, specific growth rate and length gain. There was no significant difference in all treatments for all parameters measured. The lowest weight gain and specific growth rate were recorded in fish fed 45% protein level (T2) group. Fish in T3 (50%) achieved the highest survival rate while T1 (40%) group recorded the lowest. The best and lowest Feed Conversion ratio (FCR) was recorded in the control group. In conclusion, the performance of formulated feed using fish waste is similar to commercial pellet as no significant difference can be observed in all parameters measured.

n eight week study was conducted to assess the performance, carcass characteristics and haematological indices of broiler chickens provided water from different sources. One hundred and fifty day - old broiler chicks (Arbor acre) were randomly allocated to five treatment groups (rain, stream, pipe borne water, well and borehole water respectively) in a completely randomized experimental design. The borehole water was obtained from a residential building, about 500 m to the experimental site (Federal College of Agriculture (FECA), Akure, Nigeria). Rainwater was harvested when it rained and was stored in plastic containers before it was used. It was not stored for more than three days before use. Stream water was obtained from a stream that flowed close to the students' residential area of FECA. It is sometimes drunk and is typical of streams that flow in a typical village community. Well water was obtained from a well sunk within the premises of the FECA. It was a well from where people fetched water for domestic use and was provided to the birds without prior treatment. Pipe borne water was obtained from the Water Corporation Mains that supplies FECA and Ijapo Estate, Akure. Results from the experiment revealed that there were no significant (P>0.05) differences among the treatments in terms of water intake, feed intake, weight gain, feed conversion ratio, carcass characteristics, relative weight of some organs, muscle dimensions and haematological parameters. Pipe borne water had the highest numerical values (P>0.05) for most of the performance and carcass characteristic indices measured, such as daily water intake (181.53±14.6), cumulative water intake (8.90±.71), daily feed intake (106.27±4.15), cumulative feed intake (5.21±0.20), daily weight gain (38.53±2.38), total weight gain (1.89±0.12), final weight gain (1.98±0.12), percent dressed weight (97.11±0.16%), percent eviscerated weight (81.86±3.26%), relative weights of drumstick (99.37±5.43g/kg), wings (89.10±9.69g/kg), chest (170.08±6.59g/kg) and back (159.40±18.90g/kg live weight) respectively. Water from different sources (rain, well, pipe borne water, borehole and stream) had no significant (P>0.05) effect on the performance indices, considered in the study for broiler chickens. This implies that the aforementioned water sources can be used to raise broiler chickens provided such water is free from any contaminants that could impair the health of the birds.

AbstractWhen designing environments for animals, the quality of space as well as the amount of space should be considered. In this study the influence of an opaque barrier on the aggressive behaviour and growth of Large White Χ Landrace piglets that were weaned at 24 days was examined. The behaviour and weight gain of 120 piglets were recorded during a 4-week period following weaning. These piglets were housed in either a conventional flat-deck pen or a straw pen, with or without an opaque barrier. There was no significant difference between the two types of accommodation in the frequency of aggressive interactions that occurred during the weaning period but where a barrier was present the frequency of aggressive interactions was 40% lower during the 1st week after weaning and growth rate was proportionately 0·15 greater. Piglets that were the recipients of most aggressive behaviour used the barrier most frequently during the weaning period and barrier users gained the most weight during the week immediately following weaning.It was concluded that a barrier improved the weaning environment because it offered piglets an escape route during the period when most aggressive interactions occurred. A barrier may be an effective way of improving the welfare of animals housed in confined conditions.
