Definite Pattern

Ten Fingerlings each of Clarias gariepinus were fed with five experimental diets compounded with major nutrient sources with varying percentages of protein obtained from housefly Musca domestica maggot meal (HFMM) at 0%, 12.5%, 50% and 100% inclusion in diets I, II, III, and IV respectively. Diet V was made up of HFMM only. The effect of the varying protein content on the growth and development of the fingerlings were studied for 8 weeks. The best-feed conversion ratio was observed in diet II (25% maggot inclusion) while the least was in diet V (whole maggot). Feed utilization was highest in diet I (0% maggot). Fish fed on diet I recorded the highest growth rate (SGR) and was least in fish fed on diet V (whole maggot). Also, the highest protein efficiency ratio (PER) was recorded in fish fed on diet Ill and least in fish fed with diet V. Proximate analysis of fish fed on the different diets revealed that crude protein was least in fish without experimental diet (70.05%) and highest in fish fed with whole maggot (diet V) 76.31%. The ash content of fish carcass composition before and after feed trial did not follow a definite pattern. The results of the study showed that the survival and the development of fingerlings were best when maggot was used as supplement.

This study was conducted to evaluate the suitability of soaked <em>Bauhinia monandra</em> (Kutz) seed as alternative protein source for <em>Clarias gariepinus</em> and to determine cost of feed compounded. The proximate analysis of the diet (crude protein, crude fibre, ash, moisture content and lipid) were determined using AOAC (1980). Data for each parameter was subjected to one way analysis of variance (ANOVA) while means of various results were compared at 5% level of significance. A preliminary study was conducted to determine the best processing method that reduced anti-nutrients to the minimum level without impairing nutrients composition. Boiled, toasted and soaked seeds were used. <em>Bauhinia</em> seeds soaked for 96 hours had least concentration of anti-nutrients. The experimental diets was formulated to contain soaked <em>Bauhinia</em> seed meal (SBSM) at levels of 25%, 50% and 75% inclusion (Diets 2, 3 and 4 respectively)  with two diets acting as control (Diets 1 and 5). All diets were isonitrogenous (40% crude protein) and isocaloric (3212kcal/kg). A 12 weeks feeding trial was conducted using juveniles which were randomly distributed into 12 improvised non-recirculatory and semi-flow through indoor plastic tanks (52cm X 34cm X 33.5cm) at a stocking rate of 10 fish per tank and three (3) replicates per treatment. The experimental design was complete randomized. The fish were fed at 5% body weight, twice daily. Diets with higher inclusion levels of SBSM (diets 3 and 4) significantly depressed growth performance of fish. The variations observed in the Specific Growth Rate (SGR), Feed Conversion Ratio (FCR), Feed Efficiency Ratio (FER) and Protein Efficiency Ratio (PER) were associated with the anti-nutrients present in the diets, these parameters reduced with increasing levels of SBSM in the diets of fish. Based on the relative cost of diets per unit weight gain and protein gain, diet 2 (25% SBSM) was most economical. The results suggested that SBSM can be used to substitute up to 25% levels of dietary protein in <em>C. gariepinus</em> juveniles without significant reduction in growth.

 Best diet of the fish is the sole of production of aquaculture. Growth performance of Clarias gariepinus on the basis of formulated feed supply was carried out from 7th March to 6th May, 2019 in the laboratory of P.G.Campus, Biratnagar in which 130 juveniles (each of 10±0.11 g.) of catfish were cultured in 13 aquaria feeding with treatment diets having crude protein level 35%, 40%, 45% and 50% for treatment and commercial diet for control. There are no significant differences between the water quality parameters and body weight gain (p>0.05) in all treatments. The highest body weight gain (7.31±0.11 g; 65.20%) and SGR (13.051±1.15 g) was observed in fish fed with T C (45% protein level). This value was lowered than value of control(C) i.e. 7.59±0 g; 69.88% and 13.55±0 g respectively. Feed conversion ratio (FCR) was best (13.28±1.89 g) in T D (50% protein level feed). Its value was larger (7.52±1.11 g) in T C than C (7.15±0 g). Mortality rate was highest in T C and C i.e. 30% and lowest in T A and T B i.e. 23.33%. Weight gain of the fish increased with increasing protein level in diet till crude protein level 45% then it was dropped at the diet with protein level 50%. The best weight gain was observed in 7th week having crude protein level 45%. The diet with protein level 45% is suggested for farmers concerning the fish (Clarias gariepinus) in the aquaculture.

Two experiments on the effect of dietary protein/energy ration on growth and carcass composition in Daldale wether lambs were carried out.In experiment 1, two groups of eight lambs in each group were fed in pens at a restricted intake (30 g air-dry feed per kg liveweight) either on a high protein/high energy diet (HP/HER) (20.7% crude protein) or on a low protein/high energy diet (LP/HER) (10.3% crude protein). The lambs were grown from 24.8 kg liveweight until slaughter at 37.5 kg. In experiment 2, two groups of eight lambs in each group were fed in pens a pelleted diet ad libitum, either on a high protein/high energy ration (HP/HEA) or on a low protein/high energy ratio (LP/HEA). The lambs were grown from 22.0 � 0.8 kg liveweight until slaughter at 37.5 kg. Those lambs on the HP/HE diets grew significantly faster than their counterparts on the LP/HE diets. Accordingly, animals given the HP/HE diets showed a superior feed conversion ratio than animals given the LP/HE diets. Despite these differences, there was no overall differences between treatments either at restricted or at ad libitum intake in the weight of carcass, the dressing percentage, and in the chemical composition of the carcass. In general, the carcasses produced contained a similar amount of fat (30.6%-32.9% of carcass). It was concluded that varying protein to energy ratio in diets affected liveweight gain and feed conversion ratio, but did not affect carcass composition.An experiment was conducted on the diets to investigate some aspects of digestion in the stomach and intestines at the two levels of crude protein.Dietary crude protein level had little effect upon the apparent digestibility of organic matter (OM) and neutral detergent fibre in the whole tract, the proportion of NDF digested in the stomach, the total volatile fatty acid concentration (VFA) in the rumen and the proportions of individual VFA.The flow of rates of digesta from the rumen and abomasum were also similar for the two diets. However, the proportion of the total digestion of OM occurring in the stomach decreased, while the flow of total N and crude protein (CP) (total N minus ammonia N x 6.25) to the intestines and the amounts of N and CP digested therein was higher on the HP diet.The data from the digestion experiment showed that the amount of digestible CP in the intestines per unit of digestible OM intake did not affect carcass composition.

Fecal Collection

Two experiments were conducted with 28-d-old pigs to study the effects of 0 or 8% added fat to the diet when constant nutrient to energy ratios were maintained. In exp. 1, 24 pigs were assigned to one of six treatments. Pigs were fed either ad libitum or restricted. Digestibility values were determined using fecal and terminal ileum collection methods. Only apparent ether extract digestibility increased (P < 0.001) with the addition of fat to the diet. Ether extract digestibility coefficients determined by the ileal collection method were significantly larger (P < 0.001) than those determined by fecal collection. In contrast apparent energy, dry matter and crude protein digestibilities based on ileal collection were significantly lower than the equivalent digestibilities based on fecal collection. The second experiment compared the performance and carcass composition of pigs fed the same diets as in exp. 1. Pigs 7 d after weaning contained less fat (P < 0.01), more water (P < 0.001) and more protein (P < 0.01) than pigs at weaning. Carcass composition of the pigs 7 d after weaning and at 20 kg liveweight were similar (P > 0.05). Feed conversion efficiency was improved (P < 0.001) by the addition of fat to the diet.

Aiming at finding cheaper and still efficient feed for aquaculture species 56 days feeding trial was conducted on African catfish (Clarias gariepinus) post fingerlings, fed on five diets with a 40% crude protein target in which maize was replaced with maize offal meal at 0%, 25%, 50%, 75%, and 100% respectively. Ten fish each were stocked in a plastic aquarium tank containing 20 L of water. The fish were fed at 5% body weight divided into two rations ginen at the hours of 8-8:30 am and 5-5:30pm. Growth parameters showed increase with increase in maize offal based diets, with observed weight gains of 72.42, 79.00, 95.92, 130.83 and 65.83 for diets 1, 2, 3, 4, and 5 respectively. Feed conversion ratio (recorded best in 75% maize offal based diet substitution, while the poorest was recorded at 25% maize offal diet replacement, followed by the control diet (100% maize diet). 75% maize offal replacement recorded the highest specific growth rate (p<0.05).There was significant difference (p<0.05) in the ash content, crude fiber and energy level in the fish carcass. The cost of feed used throughout the experimental period was not significantly (p>0.05) influenced by the increasing level of maize offal as a replacement for maize in the diets, as the costs were comparable. However, this study reveals that maize offal meal can successfully replaced maize up to 75% in the diet of Clarias gariepinus post fingerlings without adverse effect on growth, carcass composition and economics.

The study examined the effect of partial replacement of fishmeal with Spirulina platensis (SP) and Chlorella vulgaris (CL) powder in the diets of African catfish Clarias gariepinus (Burchell 1822) fingerlings on growth performance and body composition. Nine diets (45.14-48.45% crude protein) consisting SP or CL as fishmeal replacement at zero (control), 12.5, 25, 50 and 75%, were fed to triplicate groups of 10 fingerlings (7.82±0.08 g) each for 56 days. The results showed statistically higher weight gain, specific growth rate, protein efficiency ratio, relative growth rate, Fulton’s condition factor (K) and a corresponding lower feed conversion ratio when the replacement of C. vulgaris was at 75%. Proximate analysis revealed a significantly greater carcass protein in the SP12.5% and the highest flesh lipid and gross energy in SP75% groups. Flesh lipid increased with increasing SP and CL levels. Polynomial curve estimation regression analysis revealed the optimum fishmeal replacement levels for best growth are at 68.5 and 69.4% for SP and CL, respectively. CL was found to be more efficient in terms of growth and effective feed utilisation than SP.

The effects of replacing soybean meal with graded levels of fermented Senna obtusifolia seed meals (SOSM) on the growth performance of Clarias gariepinus were investigated. Five isonitrogenous (42% crude protein) and isocaloric (25.7% NFE) diets were formulated in which fermented replaced soybean meal (SBM) at 0% (SOSM0), 25% (SOSM25), 50% (SOSM50), 75% (SOSM75) and 100% (SOSM100) inclusion levels and a commercial feed (CmF) as the second control. Three hundred and sixty (360) fingerlings of (Clarias gariepinus) mean weight (2.85±0.01g) were stocked at (20) fish per tank volume in triplicate groups per treatment and fed 3% body weight twice a day of the experimental diets for 180 days. The feeding rate was adjusted after weighing. The water qualities were within range recommended for Clarias gariepinus. There were no significant differences (p> 0.05) in growth performance and nutrient utilization between the control groups and those fed the fermented SOSM diets at 25%. The commercial, 0% and 25% groups had the highest mean weight gain (279 to 280 g), significantly (P<0.05) superior to the groups that received the, 50%, 75% while the group that received 100% SOSM diet had the poorest mean weight gain (132.72g). Feed conversion ratios (FCR) of all treatments ranged from (1.75 to 2.18). These values increased slightly by increasing levels of fermented SOSM from 50 to 100%. The best FCR, 1.75± 0.02, recorded for fish fed 25% fermented SOSM indicated a superior level of utilization of the SOSM diet by the fish. There was no significant difference (P>0.05) in the protein intake among the group of fish fed 0 and 25%, but significant difference (P<0.05) occur in fish fed 50, 75 and 100% fermented SOSM respectively. Protein efficiency ratio (PER) exhibited significant differences (P<0.05) in all treatments except in the control diets that were not statistically different (P>0.05) from the fish fed the 25% fermented SOSM. The PER values increased among the experimental fish with respect to the quantity of total feed intake. There were no significant differences (P>0.05) in apparent net protein utilization (ANPU) among treatments CmF, 0% and 25%. The ANPU was highest in fish fed 0% fermented SOSM (91.6±0.04) while fish fed 75 and 100 % fermented SOSM in diets were 71.4±0.02 and 73.4±0.03 were the least. There was a significant (P<0.05) difference in the effect of the inclusion levels of fermented (SOSM) on final body carcass composition among treatments. This study showed that soybean meal can be substituted with fermented Senna obtusifolia seed meal up to 25% level in Clarias gariepinus diets without any negative effects on the growth and feed efficiency.

The nutritional composition of common housefly (Musca domestica) larvae and pupae meal is reported in terms of proximate analysis, amino acid profile, fatty acid composition, apparent metabolisable energy and total tract digestibility (TTD) of nutrients. Proximate analysis and TTD of meal showed larvae and pupae meal to contain, on a DM basis, a gross energy value of 20.10 MJ/kg and 20.42 MJ/kg, respectively, and an apparent metabolisable energy value of 14.23 MJ/kg and 15.15 MJ/kg, respectively. Crude protein content was 60.38% and 76.23%, with TTDs of 69% and 79%, respectively, with similarly high values reported for individual amino acids. Amino acid analysis revealed a favourable amino acid composition with high lysine concentrations but marginally low methionine concentrations. Arginine : lysine ratios of larvae and pupae meal were 0.67 and 0.91, respectively, and isoleucine : leucine ratios were 0.68 and 0.64, respectively. Crude fat contents were 14.08% and 14.39%, with TTDs of 94% and 98%, respectively, and crude fibre contents were 8.59% and 15.71%, with TTDs of 62% and 58%. Housefly larvae meal had crude protein TTD of 69%, whereas that of pupae meal was 79%. Both larvae and pupae meal had high amino acid TTDs. The TTD values of the crude fat and crude fibre were determined at 94% and 62%, respectively, for the housefly larvae, and at 98% and 58%, respectively, for the housefly pupae. M. domestica larvae meal can therefore be regarded as a good-quality protein source suitable for animal feeding.

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.

Haematological Profile

A feeding trial was carried out for 56 days to ascertain the effects of Telfairia occidentalis (fluted pumpkin) as a feed additive on the haematological profile and nutrients value of Clarias gariepinus carcass. C. gariepinus fingerlings (mean body weight 9.6g) were randomly distributed in plastic bowls at nine fish per bowl in triplicates. Five diets designated as D1 to D5 with 40% crude protein containing 0, 50, 100, 150, and 200g/kg of T. occidentalis leaf powder were fed to C. gariepinus fingerlings at 5% body weight per day. The results showed that T. occidentalis additive significantly (P≤0.05) improved the haematological parameters of the fish. The mean value of white blood cells (WBC) count (μL) in the diets fed with T. occidentalis were significantly higher (D2-D5 : 870.20, 864.80, 840.30, 876.40, respectively) than the diet without T. occidentalis (D1 783.15). A similar trend was observed in PCV, MCV, MCHC, MCH, and platelets. However, HB D1 (control) had higher values than the diet containing T. occidentalis. Meanwhile, in carcass quality, there was an increase in the crude protein of all the fish but the group that consumed T. occidentalis had a higher carcass crude protein and lower lipid, while the control had a higher lipid value. Meanwhile, the initial values obtained before the feeding trials had lower crude protein and higher lipid value when compared with the fish that was fed with the experimental diet. In conclusion, T. occidentalis leaf meal can be utilized to improve the haematological  parameters of the fish, with an increase in the WBC there is a high possibility of the fish to withstand pathogenic attacks because Blood is a major parameter that determines the physiological, immune , and nutritional status of an organism, also WBC are important blood  constituents for defense against diseases, pathogens and unwanted foreign bodies in an organism.
