Poultry Droppings

Effects of varying levels of Dried Poultry Droppings fed Clarias gariepinus were investigated for 84 days. The fish meal was partially and completely replaced by dried poultry droppings at 0%, 25%, 50%, 75% and 100% inclusions and was allotted T1, T2, T3, T4 and T5 respectively. Investigation conducted on the occurrence of microbes in the fish feeds revealed that T5 varied significantly (p<0.05) in Total Viable Count (TVC) (13.0×105 cfu/g) and Total Fungal Count (TFC) (0.70×105 cfu/g) respectively. The microbial properties of the fish carcass showed that T5 was significantly higher (p<0.05) in TVC (2.72×105 cfu/g), TCC (0.33×105 cfu/g), while T3 and T5 were significantly higher in TFC (0.20×103 cfu/g). The haematological parameters of Clarias gariepinus fed diet substituted with dried poultry droppings showed that Packed Cell Volume (PCV) (43.00 g/l) and Haemoglobin (Hb) (11.23 g/l) of T1 were significantly higher (p<0.05) than other treatments. The values of Red Blood Cell (RBC) revealed that T2 (3.77×106 mm3 ) was significantly different (p<0.05) compared to other treatments. The growth performance showed that T2 varied significantly (p<0.05) in Mean Weight Gain (MWG) (29.33 g) and Feed Conversion Ratio (FCR) (0.09). The findings of the current study imply that feed microbes affected the haematological parameters of the fish and equally suppressed the growth of the fish.

Silk Worm

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.

The Cost

The study was designed to investigate the rate of larval (maggot) production from different culture enclosures, as well as to compare the cost effectiveness and utilization of the maggot in the diet of African mud catfish, Clarias gariepinus. Musca domestica larvae were cultured from poultry dung for five week, where upon they were utilized as a replacement for fish meal in the diet of fingerlings of African mud catfish. The maggots were cultured in four different enclosures: aluminium mobile maggotry, aluminium, plastic and wooden boxes. The harvested maggots were processed by oven drying and powdered as maggot meal. The maggot meal was used to substitute fish meal in eight diets with different inclusion levels of 0% (control), 20%, 30%, 40%, 50%, 60%, 70% and 80%. The formulated diets were fed to C. gariepinus fingerlings in triplicates for 10 weeks. The growth, nutrient utilization and survival of fish were monitored during the experimental period. The cost effectiveness of different culture enclosure was studied. Results indicate that aluminium box was the best option, giving the highest weight of maggot production, and was the most cost effective of all the culture enclosures studied. Significant differences (p < 0.05) were recorded in weight gain of fish between the control and the maggot meal-based diets, while the highest weight gain was observed in fish fed 70% maggot meal-based diet. Specific and relative growth rates were found to be high in fish fed 60% maggot meal diet, while they were lowest in fish fed 20% maggot meal diet and the control diet. The best protein intake was recorded in fish fed the 70% maggot meal-based diet and lowest in fish fed the control diet. Survival of fish was generally high (78.3%-93.30%) and was significantly (p < 0.05) different between the fish fed as the control and the maggot meal-based diets. The study confirms that maggots of Musca domestica are suitable as partial replacement of fishmeal at 60-70% inclusion level for optimal growth performance and nutrient utilization in Clarias gariepinus fingerlings.

Effects of the supplementation of L. plantarum and L. casei based spray dried probiotic milk powder was investigated for growth performances, nutrient utilization and blood biochemistry including the cholesterol lowering effect in Charles Foster (CF) rats. Forty-eight male CF rats (21 day old) were divided into four groups and fed on basal diets supplemented with plane spray dried milk powder without any probiotic (control) and L. plantarum, L. casei and the mixed culture of L. plantarum and L. casei based spray dried probiotic milk powder, respectively in LP, LC and LPLC groups. Supplementation of diets with probiotic milk powder containing either the monoculture of L. plantarum or L. casei or their mixed culture improved growth, feed conversion ratio and nutrient utilization. Improved health performance was reflected in hemato-clinical chemistry including the hypocholesterolemic effect of the probiotic milk powder supplemented experimental rats. Although the improvement in growth, nutrient utilization and health of experimental rats was observed in all the three probiotic milk powder supplemented groups viz. LP, LC and LPLC; however these improvement was more in the L. plantarum or L. casei mixed culture supplemented group as compared to other two monoculture probiotic milk powder supplemented groups.

The objective of this study was to use the residues of fermented sardine to elaborate the acid fish silage and its use in feed for aquaculture. Biological assay was performed by feeding largemouth bass (Micropterus salmoides) fingerlings (initial weight 22g), with extruded diets (41% crude protein; 3,600 kcal/kg digestible energy) containing 0.0, 7.5, 10.0, 12.5, or 15.0% of fish silage in partial substitution to the fish meal. The feed conversion ratio and weight gain for the treatments were: 1.26 and 15.76g; 1.11 and 17.07g; 1.19 and 17.81g; 1.18 and 19.83g; 1.47 and 14.64g, respectively. No significant differences (P<0.05) were detected among the treatments. Results indicated that it was possible to use up to 15% of acid fish silage as partial substitute for fish meal in the formulation of carnivorous fish feed.

This experiment studied the effect of phytase and processing (heat treatment, grind size) on performance and nutrient utilization of broilers fed diets from 1 to 21 d that included hardred spring (HRS) and durum wheat with three grind sizes (470, 560, 630 µm) with or without heat treatment (oven dry at 80°C for 15 h) before supplementation with phytase (Natuphos® 0 or 600 FTU kg-1). All 24 diets contained 0.5 g Avizyme 1302 kg-1 and were formulated (80% wheat, 20% basal diet) to supply nutrients necessary to meet the requirements of broiler chicks, except for a low level of nonphytate phosphorus (P, 2.7 g kg-1). The medium ground HRS-based diet produced significantly better feed conversion ratio (FCR) and body weights compared with the other two grind sizes. Heat treatment significantly improved feed conversion ratio and apparent metabolizable energy (AME), protein, and P digestibility of diets. It also significantly decreased feed intake, but produced no differences in 21 d body weight. Supplementation with phytase significantly improved AME, protein, and P digestibility of test diets. The AME of diets was influenced by wheat type, processing and grind size. Phytase increased N and P digestibility. Improvements in N and P digestibility by phytase and heat treatment were dependent on wheat type and grind size.The present results suggest an advantage of both phytase and xylanase in durum- and HRS-based diets. Heat processing destroyed endogenous phytase and xylanase in wheat-based diets, and increased the levels of soluble non-starch polysaccharides. Combined phytase, heat treatment, and grind size may synergistically improve N and P digestibility. Key words: Wheat source, grind size, heat treatment, phytase, digestibility, broiler

Incorporating feed additives in diets of cultured fish is aimed at improving growth performance, immunity and carcass quality. Growth performance and some haematological parameters of Oreochromis niloticus fingerlings fed varying inclusion levels of Corchorus olitorius seeds were assessed in the study. O. niloticus fingerlings of initial mean weight 9.35±0.01g were evaluated for a period of 56 days. Five experimental diets were formulated at varying inclusion levels; 0g/100g (control), 0.5g/100g, 1.0g/100g, 1.5g/100g and 2.0g/100g of C. olitoriusseeds. All diets were isonitrogenous with each treatment having triplicates. O. niloticus fingerlings fed 1.5g/100g diet of C. olitoriusrecorded the best growth performance in terms of weight gain, feed conversion ratio (FCR) and specific growth rate (SGR). There was a significant increase in growth and nutritional performance of O. niloticus fingerlings with increasing inclusion of C. olitorius seeds (P<0.05). Significant increase in packed cell volume, white blood cell and haemoglobin were observed in treated O. niloticus fingerlings and there was no adverse effect of C. olitorius seeds on the haematological parameters of the fish. The study showed that C. olitorius seed at 1.5g/100g significantly improved survival rate, weight gain and feed conversion ratio as well as reduced mortalities in the treated groups.

Final Weight

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.

Duckweed (Lemna gibba), a nuisance aquatic macrophyte, was studied as a substitute for the partially replacement ofsoya bean meal in the diet of Clarias gariepinus fingerlings. Four dry diets formulated at 4% crude protein were fed to fingerlings at 0% (control) 10%, 20% and 30% inclusion levels of duckweed meal named as Diet A, B, C and D respectively. The fish were feed at 5% body weight and was assessed for feed conversion ratio (FCR), protein efficiency ratio (PER), survival rate among others. The highest growth performance and nutrient utilization was recorded at diet D i.e. 30% inclusion rate of duckweed with a mean weight gain of 5.45 + 0.309g, and food conversion ratioof 3.32 + 0.43 which was significantly different (P < 0.05) to the values obtained for other diets. The lowest weight gain was recorded in diet A i.e. the control diet, with a value of 3.06 + 0.03g. The result of this study showed that as the inclusion rate of duckweed is increased, there was a corresponding increase in the growth rate of the fish. The study demonstrated that duckweed can be used for the replacement of soya beans in the diet of catfish fingerlings, thus converting a nuisance weed into useful feed component for the reduction of feeding cost.

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%.
