A feeding trial was conducted to evaluate the effect of inclusion of different levels of shrimp meal with fish meal on growth, feed utilization, water quality and cost implication of the diet O. niloticus fingerlings. A total of two hundred and four (204) fish with an initial weight of 2.93+ 0.55g were stocked in twelve (12) tanks of dimension 1.8 x 1.3 x 0.36m3 for 12 weeks. Four diets (D1, D2, D3 and D4) contained 100% SM, 70% SM and 30% FM, 50% SM and 50% FM, 30% SM and 70% FM respectively, were fed twice daily to satiation. Final weight gain was 4.65±1.72g, 3.89±0.96g, 3.58±0.65g, 3.73±0.80g for the treatments respectively. The highest mean weight gain (4.98±0.31g) and specific (4.57±0.69%) growth rates were in fish fed with 100% SM (D1) and lowest (3.59±0.15g, 17.7±0.17% respectively) in fish fed 50% SM and 50% FM (D3). Protein efficiency ratio was highest in D1 and lowest in D4. Feed conversion ratio was lowest in diet D1 and highest in D4. Survival rate was good in all the treatments having the highest in D2 and lowest in D1. Diet 1 had the best growth followed by D2, D4 and D3 respectively. Cost implication and water quality parameters showed no significant differences (p>0.05) among the diets. Results showed that SM could replace FM by 100% without having any negative effect on the growth and tend to be uneconomically efficient at such inclusion level.

This study aimed to evaluate the use of acacia tannin as a toxic metal adsorbent in the diets of broilers fed with the inclusion of golden mussel meal in substitution for calcitic limestone. In the first trial, 648 male 21-day-old animals were divided among six treatments and six replicates, with 18 birds per experimental unit, organized in a completely randomized design (DIC). The treatments were diets with different acacia tannin levels (0, 250, 500, 750, 1000, or 1250 g ton-1). The results indicated that 250 g ton-1 of tannin was not harmful to weight gain, final weight, or feed conversion. Tannin levels caused a decrease in carcass yield and fat deposition and an increase in liver size. For the second trial, 900 male broilers of 21 days of age were used and distributed in a DIC, with different levels of substitution of calcitic limestone by the golden mussel meal (0, 25, 50, 75, or 100 %) and supplementation or not with acacia tannins (250 g ton-1), with 5 replicates and each experimental unit being composed of 18 birds. The performance data show that the use of 250 g ton-1 of tannin is detrimental to bone performance and resistance and golden mussel meal can be used to substitute up to 100 % of the limestone in the diets without affecting the variables studied.

Abstract To investigate the effect of supplementation of dried biofloc produced by freeze-drying method on water quality and growth performance of red hybrid tilapia, two experimental diets (T0 treatment: 0 % biofloc; and T1 treatment: 4 % freeze-dried biofloc) were examined during 57 days of feeding trial. Diet T0 resulted in higher feed intake than T1 treatment (P < 0.05), while no significant differences were found between the two treatments in terms of weight gain, SGR, and FCR (P > 0.05). For water quality parameters, values of temperature, EC, TDS, ammonia and nitrate were significantly higher for T1 treatment (P < 0.05). While dissolved oxygen level was significantly lower for T1 treatment compared to T0 treatment (P < 0.05). Moreover, no significant differences were found for pH and salinity (P > 0.05). However, the two treatments showed water quality parameters levels within the range of standard levels of water quality for tilapia culture. In addition, proximate composition of experimental diets showed significantly higher lipid content for T0 treatment than T1 treatment (P < 0.05). While no significant differences were found between means of treatments for organic matter, protein, fiber, ash and energy contents (P > 0.05). Based on these results, a 4 % supplementation of freeze-dried biofloc can be successively included in formulated diets for red hybrid tilapia without any effects on growth in terms of weight gain, specific growth rate, feed conversion ratio and survival, and can result in acceptable water quality levels for red hybrid tilapia.

ABSTRACT Enzyme activity in solid-state fermentation complex added to diets before and after extrusion process and its influence on Nile tilapia (Oreochromis niloticus) performance were evaluated. The following enzymes were analyzed: b-glucosidase, pectinase, xylanase, endoglucanase, amylase, protease, and phytase. The fish were fed five experimental diets: a control diet (without enzyme), two test diets supplemented before extrusion (400 and 800 ppm SSF), and two test diets after extrusion or “on top” (400 and 800 ppm SSF). The experiment had a completely randomized design with four replicates and seven fish per tank. Average initial weight was 10.37 ± 0.95 g, and fish were fed four times a day to satiation for 56 days. The following performance parameters were evaluated: final weight, weight gain, feed conversion, survival, specific growth rate, and body composition. The results were compared using ANOVA and Tukey’s test at p<0.05. All the enzymes showed partial or total losses of activity when subjected to the extrusion process, except phytase. No differences were observed for survival, water quality parameters, and body composition. On-top inclusion provided a better performance, which is observed through increases in final weight, weight gain, and feed conversion. As a result, 800 ppm of enzyme complex SSF should be added "on top", that is after extrusion, to improve tilapia performance and, consequently, contribute to the fish farming financial efficiency.

This study evaluated the protein requirement of Litopenaeus vannamei post-larvae during the initial rearing phase in a biofloc system. Five different diets were evaluated with increasing concentrations of crude protein: 31.28, 36.29, 41.57, 46.34, and 51.74 g 100 g-1 CP. Post-larvae (0.16 ± 0.01 g) were stocked at a density of 450 PL m-3 in 400 L tanks. Water quality parameters were maintained within the limits recommended for shrimp farming. After 38 days, a regression analysis revealed that levels of CP content (65.29 – 72.83%), EE (10.45 – 11.65%) and body N (10.45 – 11.64%) increased with increasing protein levels in the diet. A similar trend was observed in the biofloc sludge with respect to CP and N. Survival exceeded 80%, and the shrimp with diets containing 31.28 to 46.34g 100 g-1 CP presented an increase in final weight (1.52 – 2.61 g), productivity (0.69 – 1.10 Kg m-3), weight gain (1.38 – 2.44 g), and feeding efficiency (77.28 – 101.68%), whereas these indices decreased to51.74 g 100 g-1 CP. Crude protein content from 44.26 to 47.12 g 100 g-1 provided the best growth performance during the initial rearing phase of Pacific white shrimp in a biofloc system.

The Cost

This study was designed to evaluate the effects of different Marshal breed broiler on hatching egg weights on hatching characteristics and post-hatch performances; and also to compare the cost of production of hatchlings to table size. A total of 900 hatching eggs (HE) from 40 weeks old parent stock were sorted, graded and purposively grouped on weight basis into small (<50g), medium (50-65g) and large (>65g) sizes (3 groups). Each group was allotted 300 eggs and replicated thrice, with each replicate having 100 eggs in a complete randomised design before incubation for 21 days. Candling of incubated eggs was done on day 18 on group basis and numbers of fertile eggs noted. The chicks were individually weighed and counted to determine hatchability, hatchling weight and cost of production. Thereafter, hatched chicks were allotted into the respective groups and replicated to determine the post-hatch performance. Each replicate has 45 chicks, intensively raised and were fed ad libitum with broiler starter mash for the first 4 weeks of life and broiler finisher mash from 4-8 weeks. Data generated include feed intake, final weight, mortality; weight gain, feed conversion ratio and unit cost of production of chicken were calculated. The data were analyzed by GLM of SAS and Duncan’s multiple-range test was used to separate significance of differences among treatment means at 5% significance level. The medium HE had the best fertility (93.00%), hatchability (95.67%) and cost of producing a chick (N 90.07) when compared with the small and large HEs. The large HE has the best results in terms of, final weight and weight gain, while medium HE has the best FCR, lowest mortality and least cost of production, which are significant at p< 0.05. It is therefore recommended poultry breeders and hatchery operators should consider the use of medium weight (50-65g) HEs in their operations, so as to cut down the production cost.

Different Sources

In this study, the effect of three different sources of maggot meals was conducted to evaluate the performance and slaughter characteristics of broiler chickens. Five diets were formulated to include Diet 1 (control) which contained 3.5 % fish meal, while Diets 2, 3 and 4 contained 3.5% maggot meal from broiler droppings (BMM),maggot meal from layers droppings (LMM) and maggot meal from rabbit faeces (RMM) respectively. Eighty (80) dayold unsexed Marshall Broilers were randomly allotted to four dietary treatments in a completely randomized design (CRD). Thedietary treatments had 20 birds each with two (2) replicates. Data were generated on proximate analysis and performance indices including feed intake and weight gain, slaughter characteristics and mortality rate. They were subjected to analysis of variance (ANOVA) and means significantly different were separated using Duncan's Multiple Range Test (DMRT) at 5% probability level. Results from proximate analysis showed that maggots from layer droppings had the highest crude protein and ether extract. Results on performance indices showed that birds fed on diet 3 (layer maggot meal) had significantly (P<0.05) best performance than others as regards feed intake. Layer maggot meal (LMM) in this study enhanced bestproductive performance compared to those from broiler and rabbit maggot.Birds fed layer maggot meal had the best (1.85) feed conversion ratio. They also had the best body weight gain (2501g) and feed intake (4627g). In conclusion, layer maggot meal is recommended as analternative animal protein source to expensive fish meal.

We aimed at evaluating the effects of different water temperatures on the zootechnical performance of fat snook. The experiment lasted for 60 days, which was conducted in water recirculation systems, and was randomly designed with three treatments and three replicates each, corresponding to three water temperatures (25, 28 and 31°C). A total of 225 fat snook juveniles with a mean weight of 6.45 ± 0.58 g were used, which were fed daily until apparent satiety. Zootechnical parameters were assessed and feeding rates were registered for each tested temperature. Survival rates varied from 96 to 100% among treatments. Higher values of standard and total length, and weight gain were found in 28 and 31°C (p < 0.05). With regard to final weight, final biomass, feed conversion and specific growth rate, no significant differences were observed (p > 0.05). Feeding rates did not differ among evaluated temperatures. The results show that the used temperatures did not negatively affect zootechnical performance of fat snook juveniles.

SummaryThe influence of different inclusion levels of a biologically active peptide derived from soybeans by enzymatic hydrolysis, on growth performance, foot pad lesions and carcass characteristics in broilers were examined in this study. Starter (1 to 21 d) and finisher (22 to 42 d) diets, based on maize and soybean meal, were subjected to seven inclusion levels of a commercial soybean bioactive peptide (SBP) product (Fortide, Chengdu Mytech Biotech Co. Ltd., Chengdu, Sichuan, China) at 0.0, 1.0, 2.0, 3.0, 4.0, 5.0 and 6.0 g/kg of diet. All diets were equivalent in respect of energy density, digestible amino acids and other nutrients. A total of 840, one-day-old male broilers (Ross 308) were allocated to 42 pens (20 birds/pen), which were randomly assigned to seven dietary treatments. During the starter period, there was no significant effect of SBP on weight gain and feed intake of the birds. However, a significant (P < 0.05) effect of SBP was observed for the feed conversion ratio (FCR), with SBP inclusion at 3.0 g/kg and above showing lower (P < 0.05) FCR values compared to the diet with no SBP. No effect of SBP was observed for weight gain and feed intake over the whole trial period. However, SBP inclusion tended (P = 0.06) to influence the FCR of birds. Increasing SBP inclusion level resulted in gradual decrease in FCR values, with SBP inclusion at 5.0 and 6.0 g/kg showing lower FCR values compared to the diet with no SBP. Overall, the present study suggests that dietary supplementation of SBP in broiler diets has the potential to improve FCR and to be used as a novel functional protein in poultry diets.
