| The experiment was conducted to assess the effect of substituting corn for soybean hulls on the apparent digestibility of nutrients, carcass performance and characteristics, and yield of cuts of 25 non-castrated male Santa Ines lambs with an initial body weight of 20±2 kg, at approximately 6 months of age, sheltered individually in stalls (1.10 × 1.0 m), considering a totally randomized design, fed 600 g/kg of forage and 400 g/kg of concentrate. Soybean hulls replaced corn at 0, 250, 500, 750, and 1,000 g/kg of dry matter. The intake of dry matter (DM), organic matter (OM), neutral detergent fiber (NDF), acid detergent fiber (ADF), NDF corrected for ash and protein (NDFap), total carbohydrates (TC), non-fibrous carbohydrates (NFC) and total digestible... |

| ABSTRACT This study aimed to assess the final body weight, weekly weight gain, yield, apparent feed efficiency, protein efficiency ratio, and feed intake of the Pacific white shrimp (Litopenaeus vannamei) fed four diets containing different levels of soy protein concentrate (SPC) as a replacement for fishmeal, reared in a super-intensive biofloc system. Diets consisted of replacing 209 g kg-1 fishmeal at 0, 33, 66, and 100% SPC. Shrimp were raised in a biofloc system using twelve experimental units stocked with 250 shrimp m-3 under constant aeration (O2>5mg L-1) and temperature (29±0.5 °C). No significant differences among treatments were observed based on water quality parameters. Shrimp fed diets with 0 and 33% substitution exhibited the highest... |

| Este trabalho objetivou comparar o desempenho produtivo de acarás-bandeira criados em aquários e em hapas em viveiros escavados dentro de estufa plástica em monocultivo e policultivo com camarão-da-amazônia, em duas densidades de estocagem (1,6 e 3,2 peixes 10-1 L). Utilizou-se delineamento inteiramente casualizado, em esquema fatorial 3x2, correspondendo a três sistemas de produção e duas densidades de estocagem, com quatro repetições por tratamento. Anova e teste de Tukey foram aplicados aos dados (α = 0,05). Os peixes produzidos nos viveiros em monocultivo e policultivo apresentaram mais que o dobro de ganho de peso, menor consumo de ração, melhor conversão alimentar, maior comprimento-padrão e uniformidade do lote em relação aos peixes mantidos em... |

| Developing a rearing technology requires the determination of the optimum stocking density. This study aimed to determine the best stocking density for Brycon orthotaenia juveniles grown in net cages, during the rearing phase. The research was conducted at the Experimental Farm of EPAMIG, in Felixlândia, Minas Gerais State, in the Três Marias Reservoir. 9,000 fingerlings were distributed into 12 net cages, 2 m3each, according to a completely randomized design with three replications and four different stocking densities (150, 300, 450, 600 fish m-3). Random samples were taken from each net cage, at the onset of the experiment and at 60 rearing days, to assess production parameters, specific growth rate and uniformity. We verified a positive linear... |
