| Azolla pinnata as a possible replacement of the palm kernel cake in the diet of Oreochromis niloticus. Compounded diets from a control with palm kernel cake replaced at varying levels of 0, 20, 40, 60, 80, and 100% with the aquatic fern (oven dried Azolla pinnata) were fed to Oreochromis niloticus for twelve weeks to determine the acceptability and utilization of the fern in the diet, verify the nutritional influence of the fern on the performance of the fish and possible optimum palm kernel cake replacement level. The fish readily accepted the test diets. Better growth responses were recorded in the treatments containing Azolla pinnata meal. The best response was observed in the 20% replacement level, thereby suggesting an optimum replacement. However... |

| As has been demonstrated in previous studies, Octopus maya can be fed on artificial diets. In the present study six different diets were assayed. Five diets were designed to test the effect of percentage of inclusion of fish protein concentrate (CPSP: 0, 5, 10, 15, and 20%) and were offered to octopuses as a specifically designed artificial diet. The sixth diet consisted of frozen crab (Callinectes spp) and was used as control diet. Blood metabolites and energy budget of octopuses were evaluated to determine how CPSP levels modulate the digestive capacity and allow retaining energy for growth. Wild animals (316.4 +/- 9.8 g) were used in the study. Results showed that CPSP produced a positive specific growth rate (SGR, % day(-1)) with high value in... |

| The effects of copaiba essential oil on growth performance and yield of slaughtered broilers were evaluated. Four hundred and fifty broiler chicks were distributed in a completely randomized design, with five treatments, and six replicates of 15 broiler chicks. Treatments comprised Control (commercial promoter) and four levels of copaiba essential oil, or rather, 0.15 (0.15EO); 0.30 (0.30EO); 0.45 (0.45EO) and 0.60 mL (0.60EO) kg-1 feed. The 21-day-old broilers fed on growth promoter had a greater body weight than that of birds fed on treatments with inclusion 0.30, 0.45 and 0.60 mL of essential oil (p < 0.05). Aged 40 days, only the broilers fed on treatment with high level of inclusion of essential oil showed lower body weight when compared with... |

| ABSTRACT This study was conducted to evaluate the effect of vitamin E and selenium on performance, viability, productive efficiency, and yields of carcass, major cuts, and organs of broilers from 22 to 42 days submitted to cyclic-heat stress. The experimental design was randomized blocks, in a 2 × 3 factorial arrangement with two levels of selenium (0.1 and 0.3 mg/kg) and three levels of vitamin E (300, 400, and 500 mg/kg), plus a control treatment. Animals were submitted to a natural condition of high cyclic temperature. Organic selenium levels of 0.1 and 0.3 mg/kg associated with 300, 400, and 500 mg/kg of vitamin E were tested. The level of vitamin E did not affect the performance or production efficiency of broilers in the period from 22 to 33 days and... |

| Designing strategies and policies that will alleviate poverty and improve household food security and nutritional well being is one of the most important challenges facing government policymakers in developing countries. The choice of strategies and policies depends in large part on understanding the dynamics of poverty, especially the mechanisms by which households acquire and spend income and cope with cries such as poor harvest or loss of employment. This work by Harold Alderman and Marito Gracia represents IFPRI's first comprehensive analysis of the longitudinal data on 800 households collected between 1986 and 1989 in Pakistan. This unique data set enables researchers to examine the temporal dimensions of food security, income and labor dynamics,... |

| Three species of corals Stylophora pistillata, Lobophyllia corymbosa and Echinopora gemmacea were collected from Sharm Obhur to study their chemical composition. This information was important in the investigation of their metabolic pathways and their mode of feeding. The concentrations of amino acids in these species were 9.37, 21.35 and 3.09 mg.g(-1) dry weight of coral respectively. Plant pigments were highest in E. gemmacea followed by S. pistillata and then by L. corymbosa. Lipid concentrations in S. pistillata, L. corymbosa and E. gemmacea were 1.90, 8.58 and 1.32 mg.g(-1) of total coral respectively. The fatty acid methyl esters were analyzed in these species and the most abundant saturated acids were 16:0 and 18:0, while unsaturated acids included... |

| It was evaluated the effect of diets supplemented or not supplemented with ractopamine and digestible lysine on the performance and carcass characteristics of finishing pigs. A total of 50 barrows and 50 gilts (90.2 kg ± 3.5 kg) were used. In the growth performance trial, a randomized block design was utilized in a 5 x 2 factorial arrangement, consisting of five levels of digestible lysine (0.68; 0.78; 0.88; 0.98 and 1.08%) and two levels of ractopamine (0 and 5 ppm), totaling ten diets and five replications. In a study of carcass characteristics, the same design and levels of lysine and ractopamine were used, but another factor (sex of animals- female and male) was included, totaling 20 treatments, each one with five replicates. Except for lysine daily... |

| The β-adrenergic agonist ractopamine is increasingly used in the swine industry due to higher consumer demand for leaner pork products. Redirecting nutrients to favor leanness rather than fat deposition, ractopamine improves growth and carcass traits of finishing pigs. However, the impact of this agonist on pork quality is not clearly defined. Understanding the biological effects of dietary ractopamine dose, treatment period, lysine levels, and the lysine to metabolizable energy ratio will help pork producers achieve improvements in animal performance, carcass leanness, and economic efficiency in swine production systems. |

| Considering the need to help the Cuban shrimp culture industry remain profitable, and the impact that feeding has on production costs, a research series was designed to evaluate new formulations that improve white shrimp Litopenaeus schmitti growth and reduce feeding costs. Five completely randomized experiments with 3 replicates per treatment were conducted. Juveniles (0.2-0.5 g) from the experimental farm were used. Trials were conducted at the Centro de Obtención y Cría de Larvas de Santa Cruz del Sur, Camaguey, and the Complejo Camaronero de Tunas de Zaza, Sancti Spiritus. In the first trial, 40-l plastic experimental units with 10 shrimp/unit were used to test the response of L. schmitti to the partial and total substitution (46, 59, 75, 88 y 100%) of... |

| The feasibility of substituting soybean meal for ¢shmeal diets for juvenile white shrimp Litopenaeus schmitti (0.35 0.01g) was evaluated, and an adequate substitution level was determined. Five diets were evaluated using 46%, 59%, 75%, 88% and 100% substitution levels. Pellet water stability was signi¢cantly a¡ected by dietary soybean content (Po0.05). Increased soybean content produced lower pellet stability, ranging from a dry matter loss of 14^ 22% after a 2-h immersion, and 20^33% after an 8-h immersion. After 52 days, signi¢cant di¡erences (Po0.05) were found in shrimp weight, feed conversion ratio and protein e⁄ciency ratio. The values were 0.64^1.06 g, 2.8^7.9 and 0.45^1.21, respectively, for the three measurements. Overall, better results were... |

| This study aimed to evaluate the effects of adding slow-release urea to replace conventional urea in the diet on carcass characteristics of feedlot sheep. We used 20 Santa Ines x SRD rams, with average body weight of 21.1±1.2 kgand average age of 120 days, distributed in a completely randomized design with 5 treatments. The replacement levels used as treatments were 0, 20, 40, 60, and 80%, composing diets of about 12% crude protein, with 50 % Tifton-85 hay and 50% concentrate. There was no influence of slow release urea on weight at slaughter (35.17 kg), and on hot (16.75 kg) and cold (16.24 kg) carcass weight, but the yield of these carcasses showed quadratic trend, revealing lower percentages at 48.5 and 47.63% replacement levels, respectively.
