Adding attractants can improve acceptability of artificial diets by carnivorous fish fry and fingerlings, increasing intake of unpalatable feeds and improving growth rate, while reducing feeding time and feeding wastes. This study aimed to evaluate the effects of levels of inclusion of different attractants in plant protein-based diets on the performance of largemouth bass Micropterus salmoides. Nine hundred juvenile largemouth bass (26.54 ± 1.53 g) conditioned to accept dry, artificial feed were stocked in 60, 90-L polyethylene tanks (15 fish per group) in a completely randomized design trial (n=3). Fish were fed two daily meals ad libitum at 7h00 and 17h00, for 13 days, with a diet (100% plant protein source) containing either soluble fish protein - SFP (0.5, 1.0, 1.5, 2.0, 2.5, and 3.0%); FisharonTM - FA (0.02, 0.04, 0.06, 0.08, 0.10, 0.12%); fish silage - FS (1.0, 2.0, 3.0, 4.0, 5.0, and 6.0%); a positive control diet - pCD (10% fish meal) and a negative control diet - nCD (basal diet without attractants). DL-methionine (98%) and L-lysine (80%) were added automatically by the formulation software to adjust available amino-acid profile of diets. Recorded performance data were: final weight, feed intake, weight gain and feed conversion ratio. Fish fed diet FA0.02 presented the best growth rate, best weight gain and best feed conversion ratio. Fish fed diets containing FS as attractant presented the poorest performance.

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.

Abstract Appreciative dietary desires and fabrication of fish nourishment is vital to the progress, sustainability of aquaculture and for the advanced feed mill rehearsal. Organizing fish feed includes choosing the exact feed, using an acceptable feeding technique, work out the feed charge and ensuring the cost efficiency of fish farm. The purpose of our present study was to feed the fishes with four different feeds and assessment of growth performance by length weight relationships. The growth analysis was executed by measuring FCR and related indices in gift tilapia oreochromis niloticus. Four feed composition was selected without any chemical contamination. In the present study fishes were collected from the golden farm, Neyyattinkara, Thiruvananthapuram district, South India. Fishes were introduced into four different tanks of well oxygenated good quality water. In each experimental tank, 20 fishes were introduced. For each experimental container a specific feed was fixed from 4 different diets. Every day feed was given to the fishes. They were fed two times for the period of 3 months. They were maintained to assess their growth performance. Four types of feeds used for the present study were control diet, diet 1, diet 2 and diet 3. Length and weight were measured on every 15 days interval for growth estimation. Based on the length-weight data, growth analysis was carried out by calculating relative growth (RG), relative growth rate (RGR), specific growth rate (SGR), feed conversion ratio (FCR) and the Fulton’s condition factor. The results of mean length in diet3proved the highest length of 6.455±0.46cm and diet one contain lowest length of 5.03±0.68cm. Highest weight of 96.8 ± 0.37g was recorded in diet3 and lowest weight obtained for the control diet (3.645 ± 0.306 g). In growth analysis the relative growth of fish was estimated in diet 3 having high relative growth (11.91). Relative growth rate was elevated in diet 3(1.5597). The upper limit of specific growth rate was 1.9146% noticed in diet 3. The feed conversion ratio was maximum in diet 3 (58.06) and minimum in control diet (36). The highest k value in Fulton's condition factor was noticed in diet 3(88.32).All experimental results proved that live Azolla [D3] was a superior feed for the present trials.

An experiment was conduted to evaluate the effectiveness level of corn substituted by Morinda citrifolia leaf meal in broiler ration. The use of Morinda citrifolia leaf meal substituted for corn in ration is expected to improve feed conversion in broiler chickens and produce chicken meat that safe for consumption and free of chemical antibiotics residues . Completely Randomized Design (CRD) was used to analyze data obtained from this research. One hundred and sixty chicleas (7 days aged) divided into 5 (five) treatments with 4 (four) replications and each replication consisted of 8 (eight) chicleas. Ration of treatments were a negative control diet (R0), 1% Morinda citrifolia leaf meal (R1), 2% Morinda citrifolia leaf meal (R2), 3% Morinda citrifolia leaf meal (R3) and commersial ration (R4). All treatments rations were added a natural feed additive that consist of 0,125% Curcuma and.0,075% Turmeric meal. Measured parameters were feed intake, weight gain, feed conversion ratio, mortality, percentages of carcas and abdominal fat. Results showed that feed consumption, weight gain, and feed conversion ratio were significantly (p <0.05) influenced by treatments. Mortality, percentage of carcas and abdominal fat were not significantly (p >0.05) influenced by ration treatments. Mortality rates in chickens using a ration of treatment was 0%, while using the control diet 0,78% (1 bird). The counclusion showed that the substitution of 1-2% Morinda citrifolia leaf meal in ration has better performance compared to the control diet, with improvement of feed conversion ratio was 7.57 and 9.2% respectively was more efficient than the control diets

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.

A study was conducted for eight weeks to determine the effects of raw and cooked mucuna seed meal (MSM) based diets on the performance and haematological characteristics of cross-bred weaned rabbits. Three experimental diets were formulated to contain: 0% MSM (control diet A), X raw MSM (diet B) and 20% cooked MSM (diet C). Twelve cross-bred weaned rabbits with mean initial live-weight of about 550 g were randomly assigned to three dietary treatments. The experimental design was completely randomized arrangement. The feed intakes (115.12, 114.44, 116.15g/day) and weight gains (17.19, 12.72, 14.28g/day) for diets A, B and C respectively were similar (P>0.05) for the three treatments. Rabbits fed the control diet A had the best (P<0.05) feed conversion ratio (6.68). The packed cell volume (PCV), haemoglobin (HB), red blood cell (RBC) and white blood cell (WBC) values obtained for the three treatments were not statistically different (P>0.05) from one another. The HB, RBC, WBC values of rabbits fed on 20% cooked MSM based diet had comparable values to those on the control diet. Based on the weight gain and the haematology, 20% cooked mucuna seed meal can be included in the diet of weaned rabbits.

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%.

Abstract The present study aimed to investigate the influence of supplementing beetroot (Beta vulgaris rubra) powder and its aqueous extract on the productive performance of growing geese. A total of 180 one-day-old goslings chicks of Chinese white geese were randomly distributed among five treatment groups containing three replicates of 12 birds each. Five experimental diets were formulated as follows: Control diet without supplementation (T1). In the second and third treatments, the beetroot extract was supplemented at 15, and 30 (ml/l) in drinking water; 15, and 30 (g/kg) beetroot powder (T4, T5) in basal diet respectively. Results indicated significant (p≤0.05) improvement in average body weight and weight gain from the 2nd to 12th week and total weight gain in treatment T2 and T4, which achieved the highest values compared to the control. As for feed intake, the T3 in the 6th week, T1 in the 8th week, and T2 in the 10th week were consumed a greater amount of feed compared to the other treatments, while no significant differences appeared in the 2, 4, and 12 weeks of age and in the cumulative period. No significant differences in the feed conversion ratio at age 2, 10, and 12 weeks, while the T5 in the 4th week, T2 in the 6th week, and the T4 in the 8th week, and the cumulative period showed the better feed conversion ratio compared to the other treatments. In conclusion, the supplementation of beetroot extract at 15, 30 (ml/l) or beetroot powder at 15, 30 (g/kg) improved the productive performance of growing geese.

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.

Considering the inherent attributes of cocoyam tuber meal (Xanthosoma sagitifolium) and its appropriate utilization in chicken diets may enhance performance of broiler chicken. This study was therefore carried out to determine the dietary evaluation of fermented cocoyam tuber meal as energy source in the diets of finisher broiler production. The objectives of the study were to determine the proximate composition of raw and fermented coco yam tuber meal and their anti-nutrient content (Tannin), cyanide, saponin, phytate and oxalate); to determine the effects of replacement value of maize with different levels of fermented coco yam tuber meal on the growth performance of broilers; to determine the economics of production of broilers using such diets. The fermented cocoyam was used to replace maize at various levels to determine the best level that would give optimal performance in broilers diets. One hundred and fifty (150) agrited finisher Anak broilers at 4 week were used for this experiment. The proximate composition of fermented cocoyam meal showed that it contained 19.15% moisture, 1.30% ash, 3.56% crude protein, 5.30% crude fiber, 1.90% ether extract and 25.48% NFE. In the finisher trial, the replacements were 25%, 50%, 75% and 100% of FCYM for maize in the control diet. Each finisher diet was fed to a group of 30 finisher broilers at 4 weeks using Completely Ramdomized Design (CRD). The parameters measured include: initial body weight, final body weight, body weight gain, feed intake, feed conversion ratio, cost of production and carcass characteristics. In the finisher feeding trial, the broiler group on 25% FCYM recorded the highest body weight gain which was significantly different (P<0.05) from those on the control diet and the rest of the treatment groupsThe internal organs expressed as percent of the live weight were not affected by the treatments. The cost of production (N135.28) was lowest for diets 5 (100% FCYM) while the highest was the control treatment. The result of the trial have shown that 4 day fermentation of cocoyam tubers for processing broiler diets was quite an effective method of processing cocoyam tubers for use in broiler diets because fermentation reduced the anti-nutrient contents in cocoyam tubers. It was concluded that fermented cocoyam tuber meal could be used in the diet of finisher broilers up to 100% without affecting body weight gain, feed intake and feed conversion ratio as indicated in this study.
