This study was conducted to examine the effect of feeding at different time intervals of the day on the growth efficiency of African catfish (Clarias gariepinus, Burchell 1822). Juveniles of African catfish Clarias gariepinus with an average weight of 16.0±0.20g were randomly stocked into four treatment groups (T1, T2, T3 and T4) at 10 fish per group using a completely randomized design (CRD). The treatment groups were T1 (Fish fed once daily), T2 (Fish fed twice), T3 (Fish fed Thrice daily) and T4 (Fish fed four times daily). They were all fed 3% of their body weight. Data obtained was analysed using Genstat package while means where separated using Duncan Multiple Range Test. The result of the study showed that the highest weight gains of 104.49g was recorded in Treatment 3, this was followed by Treatment 2 with a mean weight gain value of 92.42g. The least value of weight gain (76.74g) was recorded in Treatment 1. Also, the highest feed intake value of 142.83g was recorded in Treatment 3, this was followed by Treatment 2 with a mean feed intake value of 135.12g. The least value of feed intake (112.95g) was recorded in Treatment 1. The feed conversion ratio and Protein Efficiency ratio (PER) also followed similar trend as that of weight gain and feed intake. The highest PER value of 2.10 was recorded in Treatment 3, this was followed by Treatment 2 with a mean PER value of 1.69. The least PER value (1.39) was recorded in Treatment 4. ANOVA showed that there was significance difference (P<0.05) in the PER value between Treatment 1, 2 and 3. However, Treatment 1 was not significantly different (P>0.05) from Treatment 4. At the end of the Study, three times feeding per day was found to be sufficient for maximum growth as it recorded the highest value for growth parameters monitored and was significantly different from other treatments.

 No or little information on the use fresh (wet) housefly maggots (Musca domestica) in African catfish (Clarias gariepinus) fry feeding. Therefore, this study was conducted to investigate the effect of feeding on fresh (wet) housefly maggots with or without artificial diet on water quality, growth performance, survival percentage and feed utilization of African catfish fry under laboratory conditions. Housefly maggots produced from a mixture of poultry droppings and foods wastes, it was used to replace artificial feed at 0, 50 and 100% levels. Catfish were fed artificial diet alone (Feed 1), fresh (wet) housefly maggots alone (Feed 2), and 50% fresh housefly maggots with 50% artificial diet (Feed 3) were prepared and tested on triplicate groups of African catfish fry (initial weight of 0.25±0.02 g) for 60 days. Results showed that final weight (g/fish) was significantly highest (P£0.05) in fish fed feed 3 (6.03±0.08), followed by fish fed feed 2 (4.62±0.27), followed by fish fed feed 1 (3.15±0.68). Specific growth rate (%/day) was also significantly highest in fish fed feed 3 (5.31±0.10), followed by fish fed feed 2 (4.86±0.03), followed by fish fed feed 1 (4.18±0.24). The same trend was observed with total weight gain, percentage weight gain, daily growth rate and relative growth rate. Feed intake and protein intake were significantly highest (P£0.05) in fish fed feed 3 and fish fed feed 2, followed by fish fed feed 1. While, feed conversion ratio (FCR) and protein efficiency ratio were not significantly (P>0.05), but the improvement in FCR recorded in catfish fry fed feed 3 and feed 2 under the experimental conditions. Survival percentage was within the range 55–75%, with insignificant differences (P>0.05) among treatments. The water quality parameters such as temperature, pH, dissolved oxygen, total ammonia, nitrite and nitrate were not significantly (P>0.05) among the treatments and were tolerable for fish culture. Accordingly, use of the 50% fresh (wet) housefly maggots with 50% artificial diet in African catfish fry feeding had positive effect on growth performance and reduce of the feed cost.

Immuno-nutrition studies have shown that some nutrients are linked to the immunological status of fish. Growth performance, nutrient utilization and intestinal microflora were examined in Clarias gariepinus. The 120 C. gariepimus fingerlings (weight, 2.33±0.07g)were fed Aloe barbadensis leaves-paste supplemented diets in 40L freshwater-filled plastic tanks ad libitum twice daily for 12 weeks. The experimental diets containing 40% crude protein were supplemented with three concentration of A. barbadensis leaves-paste: ABL1-1%; ABL2-2%; ABL3-3% and control-0%. Mean weight gain (MWG) and percentage weight gain (PWG) increased (p<0.05) as the concentration of A. barbadensis increased. MWG (17.95±0.78) and PWG (772.2±54.94) were highest in fish fed ABL3 and lowest MWG (11.92±1.16) and PWG (17.95±0.78) in fish fed control diet. Nutrients were better utilized among the diets supplemented group at different significant levels (p < 0.05). The highest value of ANPU was observed in ABL1 when compared to all other treatments including the control. Survival rate decreased as concentration of paste increased. There were no significant differences (p>0.05) in the total bacterial counts (TBC) in A. barbadensis leaves-paste supplemented diets and the control having the highest TBC (23.67 ±0.88 x 105 CFU/ml). Growth of total fungal counts (TFC) was not observed in ABLI. There was a reduction in TFC as the concentration increased in the other supplemented diets, and the control having the highest TFC (7.67 ± 0.44 x 105CFU/ml). The study concluded that inclusion of 1% A. barbadensis leaves-paste as supplement in the diet could effectively improve the growth performance, nutrient utilization and survival of cultured C. gariepinus. A. barbadensis leaves-paste could also reduce the microbial load of the fish.

Background: The major problem facing fish feed manufacturers and fish nutrition is the increasing competition for the same feeding stuff between man and the fish feed industry due to their conventional status. This has brought about the high price and scarcity of such feedstuffs. This research is aimed at evaluating the potentials of using graded levels of grasshopper as protein sources in the diet of African catfish. Methods: Four feeding trial were set up with percentage inclusions of the grasshopper meal of 0% [diet] 1, 5% [Diet II], 10% [Diet III] and 15% [Diet IV]. The feed was given to the fish for 8 weeks. Fish survival rates, weekly weight gain, and length gain were recorded. Results: The results revealed that the. The survival rate of fish was over 90% for all experimental diets and it was significantly improved in the fish fed on 10% & 5% of grasshoppers (95.97% & 97.5%, respectively) when compared with the control group (91.04%). Percentage weight gain of the control group was significantly lower (803.00 %) compared to fish fed on 5% of grasshoppers (1092.00%). The highest fish length gain was also recorded fish fed on 5% of grasshopper (8.65 cm) while the least length gains (5.43 cm) was recorded for the control group in relation to all other fish groups which have received grasshopper at all inclusion levels. Conclusion: It is concluded that grasshopper inclusion in diet has the potential to enhance the survival rate and modulate growth parameters in Clarias gariepinus. Therefore, Grasshopper can be used as a feed additive in aquaculture to improve fish growth and production.

This study assessed the effects of microalga Phaeodactylum tricornutum supplement on the gustation, stomach histology, growth performance and nutrient utilization of Clarias gariepinus juveniles. One hundred and fifty (150) C. gariepinus juveniles of mean weight 20.05±0.05g were distributed into 15 plastic tanks (40×30×35) cm3. Five graded levels (0.00 (control), 0.50, 1.00, 1.50, and 2.00g/100g of P. tricornutum supplements were included in the diets of C. gariepinus denoted as Control, PT1, PT2, PT4 and PT5, respectively. Fish were fed for 56 days at 5% body weight. Results at the end of the experiments showed that the highest body weight was recorded in fish fed 1.5g/100g P. tricornutum diets. The best feed conversion ratio, specific growth rate, protein efficiency ratio and percentage survival was found in PT3. There was significant difference (p<0.05) in the feed intake of fish with PT4 having the highest feed intake. The stomach histology revealed increase in the gustation cells in the stomach of experimental fish with increasing levels of P. tricornutum supplementation. This study showed that the inclusion of P. tricornutum supplement at 1.5g/100g level in the diet of C. gariepinus juveniles improved the gustation, growth performance and nutrient utilization of C. gariepinus.

SUMMARYSeven research and teaching centres have co-operated in an experiment involving 154 sows. The experiment compared the effect of feeding four different patterns of feed intake during pregnancy upon reproductive performance of sows. In each case approximately 220 kg of feed were given during each gestation according to four patterns of intake designated Constant (C), Low-High (L-H), High-Low (H-L) and High-Low-High (H-L-H). During lactation all animals were given a daily ration of 3·7 kg of feed for litters of five pigs or less, and 0·4 kg for each additional piglet. Wherever possible the sows remained on the same nutritional regimes for three parities.Although the pattern of feed intake slightly affected the live-weight changes of the sows during the course of pregnancy, the treatments had no significant effects on overall change in weight of the sows in pregnancy or in lactation in any of the three parities. The live weights of the sows at the end of the third parity were very similar for all treatment groups.The patterns of feed intake had no appreciable or significant effect on the numbers of pigs born, their average weight at birth or upon the numbers of pigs which survived to weaning at 6 weeks or their live weight. The health and breeding regularity of the sows were also unaffected by the treatments.There were differences between the centres in many of the variables which were compared, but there was no evidence of any important centre × treatment interactions.It is concluded that, at the levels of intake given in pregnancy and lactation in this experiment, there are no beneficial or detrimental effects of changing the pattern of intake during pregnancy.

There is paucity of information regarding efficiency and suitability of most imported floating feeds used for growing catfish in Nigeria. This study therefore determined proximate compositions of three commercial floating fish feeds (Vital Feed, Top Feed and Allier Aqua Feed) and their effects on growth parameters when fed to juvenile African catfish (Clarias gariepinus). 65 litre capacity rectangular plastic tanks were stocked with healthy juveniles catfish of similar average weight were fed with these feeds for a period of 56 days (8weeks at the rate of 20 fish per tank. A triplicate trial was maintained for each feed, totalling nine tanks in all and 60 fish per feed. The tanks were labelled based on the type of feed. The rearing water quality parameters were monitored throughout the experiment. The results indicated that catfish fed with Top Feed had significantly (p80%) were observed in all groups while water quality parameters were not affected due to the feed offered. The results of the proximate composition attested to the fact that feed with high protein and lipid contents results in better fish growth i.e. Top feeds with high protein (45.16±2.73) and Allier Aqua with high (13.00±2.11) content. Variations in growth parameters and estimated cost of feeding observed in the present study imply that catfish that catfish farmers should exercise great caution in selecting commercial floating feeds for their fish since these feeds produce different growth effects on fish.

A feeding trial was conducted to examine the dietary effects of using African Palm weevil in the diet of Catfish. Five experimental diets containing 40% crude protein were formulated, four of these diets contained defatted African palm weevil larvae meal at varying inclusion levels denoted as APW25%, APW50%, APW75% and APW100% while the diet with fish meal (APW0%) served as control diet. The experiment was conducted in triplicates for 10 weeks using 15 aquaria glass tanks with 10 fish per tank. The percentage weight gain was significantly different (P>0.05) across the fish fed experimental diets, with the highest percentage weight gain (1118.30g) recorded in fish fed diet APW100 and the lowest percentage weight gain (749.40g) recorded in fish fed diet FM. The feed conversion ratio (FCR) were not significantly different (P<0.05) across the experimental diet. The highest FCR value (1.48±0.42) was recorded in the fish fed diet FM while the lowest FCR value (1.06±0.01) was recorded in fish fed diet APW100. There were no significant differences (P>0.05) in the PER among the experimental diets. It could be concluded that defatted African palm weevil larvae meal in the diet in replacement of fishmeal.in the diet Clarias gariepinus juvenile.

In a completely randomized designed, two hundred and forty day-old broiler chicks were randomly assigned to four dietary treatments containing 0, 2.5, 5.0 and 7.5mg kg-1 Lcarnitine. Each of the diets contained equal amount of maize and cashew nut reject meal (CNRM). The birds were randomly divided into sixteen groups of fifteen chicks each after weight equalisation. Each diet was assigned to four groups of birds representing four replicates per experimental diet. Measurements taken during starting and finishing phase included average live weight, average weight gain, average feed intake while feed to gain ratio was calculated. Nutrient digestibility of the experimental diets was also evaluated. Results between 0-4weeks indicated that body weights ranged from 673.71g in the birds that received 2.5mgkg-1 to 700.21g in the birds that received 7.5mgkg-1 L-carnitine. Weight gain and feed intake values were significantly (P<0.05) affected by L-carnitine levels. Feed to gain ratio values were elevated when birds were fed 0 and 2.5mgkg-1 L-carnitine levels. Evaluation of nutrient utilization showed a significant (P<0.05) influence on crude protein and ether extract values. Between 5-8 weeks of rearing, feed intake increased (P<0.05) as Lcarnitine levels increased in diets while lower (P<0.05) feed to gain value was recorded at high level of dietary L carnitine. Nutrients utilization parameters were not affected (P>0.05) during finishing phase. Overall results showed that highest body weight and weight gain were obtained in the group that received 7.5mgkg-1 L-carnitine supplementation. The study showed that supplementing CNRM diets up to 7.5mgkg-1 is beneficial to growth and utilization of broiler chickens. However, this was more effective at the starter phase.

One hundred and twenty Clarias gariepinus fingerlings (2.33 ± 0.07 g) were fed with 40% crude protein diets containing three concentrations of Aloe barbadensis leaves-paste: ABL1, 1%; ABL2, 2%; ABL3, 3%, and control, 0% ad libitum twice daily for 12 weeks. Mean weight gain and percentage weight gain increased (P < 0.05) as concentration of A. barbadensis increased. Survival rate decreased as concentration of paste increased. Differences (P < 0.05) seen in packed cell volume (PCV), haemoglobin (Hb), and red blood cell (RBC), thus highest in ABL3: PCV (36.67 ± 0.89%), Hb (12.37 ± 0.37 g dl–1) and RBC (3.47 ± 0.08×106 L–1) and lowest in control: PCV (22.0 ± 0.58%), Hb (7.37 ± 0.20 g dl–1) and RBC (2.07 ± 0.06 ×106 L–1). Liver histology of control fish was normal, while fatty degenerations were seen in the treated fish. The histology of fish kidney was normal in all treatments. The study concluded that 1% A. barbadensis leaves-paste could effectively improve growth performance, nutrient utilization and survival of cultured C. gariepinus.
