| Handling of live fish is inevitable in fish farms and causes a number of adverse physiological reactions, thus requiring the use of anesthetics. The main goal of the present work was to evaluate the efficiency of clove oil as an anesthetic for juvenile tilapia (approximately 55 g and 13 cm) during handling. In the first experiment, fishes were exposed to an anesthetic bath at six concentrations (80, 100, 150, 200, 250 and 300 mg L-1). Subsequently, the induction time was assessed for different stages of anesthesia. In the second experiment, different times of exposure to anesthesia were tested, aiming to assess the safety margin of the anesthetic. Finally, we evaluated the responses to stress after exposure to 250 mg L-1 anesthesia. The following... |

| Two experiments were performed to determine the influence of threonine-lysine (Thr:Lys) ratio on requirements of digestible lysine (Lys) in low crude protein diets for broilers in the growth phase. In the first experiment, a total of 480 Cobb 500 male broilers were distributed in a completely randomized experimental design with four dietary Thr:Lysratio (57.0; 60.5; 64.0 and 67.5%) and with five replicates of 24 birds each. No significant differences were reported in weight gain, feed intake, poultry manure humidity, carcass and meat yields. However, the feed conversion was increased linearly as dietary Thr:Lysratio was increased. In the second experiment, a total of 400 Cobb 500 male broilers were distributed in a completely randomized experimental design... |

| This study aimed to evaluate the digestibility of tilapia by-product protein hydrolysate powder (TBHP) from tilapia filleting by-product, and its inclusion in diets for Nile tilapia larvae. In order to determine the apparent digestibility coefficients, two diets were formulated, the reference diet and the test diet (20% of TBHP) and, to evaluate the inclusion, six diets were formulated, which were with 0.0, 2.0; 4.0; 6.0, and 8.0% of TBHP. The apparent digestibility coefficients of crude protein and gross energy were 89.5 and 98.3%, respectively. At levels above 4.0% of inclusion of TBHP, the weight, final length and weight gain were impaired, however, survival rate was higher (p < 0.05). The TBHP can be used in diets... |

| This study investigated the tiller dynamics of Italian ryegrass (Lolium multiflorum Lam) under low and high stocking rates. These rates were determined by heifers exclusively on pasture or grazing and supplemented with oats and corn grain. The experimental design was completely randomized with repeated measurements over time, with two stocking rates, three and six replications of area for low and high stocking rates, respectively. The appearance rate (1.0 tillers tiller-1 m-2), survival rate (0.8 tillers tiller-1 m-2), population stability index (1.6) and site occupation (0.3) were similar for high and low stocking rates. The tiller density was similar for different stocking rates. The... |

| The objective of this work was to evaluate the tiller population density in Urochroa decumbens pasture deferred for 95 and 140 days, aiming to determine the best strategy for nitrogen fertilization. Four fertilization strategies at the beginning and end of summer (0-0, 100-0, 50-50, 0-100 kg ha-1 of N) were studied, respectively, with four repetitions. For the pastures deferred for 95 days, the population densities of vegetative tillers were greater (p < 0.05) for the strategy 0-100. At the end of the deferment period, the weight of the vegetative tillers per hectare was greater for the strategy 0-100, followed by the strategy 50-50. The densities of vegetative tillers, evaluated in the pastures deferred for 140 days, were greater (p < 0.05)... |

| This study evaluated the influence of nitrogen levels (N) and plant density (D) on the tillering dynamics of Tanzania guinea grass (Panicum maximum Jacq.). Treatments were arranged in a completely randomized block design with 12 treatments and two replicates in a factorial scheme (4 × 3) with four levels of N (0, 80, 160 or 320 kg ha-1 N) and three plant densities (9, 25, and 49 plant m-²). Higher number of tillers was observed in the treatment with 9 plants m-² and under higher levels of N, especially in the second and third generations. Still, the N influenced quadratically the appearance rate of basal and total tillers, which were also affected by plant density and interaction N × D. However, the appearance rate of aerial tiller was not influenced by... |

| For this research 48 male lambs were divided in randomized blocks in a factorial design, having as factors sexual condition (castrated or uncastrated) and time on feed (36 or 78 days). High grain diet was monitored daily to measure the performance of the animal nutrition. The characteristics of the carcass and meat were taken for the fatty acids profile and sensorial analysis. The effect of the factors as sexual condition and time on feed, and the interaction between them, were evaluated by analysis of variance using the GLM procedure of SAS software and the treatment averages were compared by Student's T test. The uncastrated animals presented greater weight gain and dry matter intake, better feed efficiency, and larger loin area. More time on feed... |

| The present work aimed at determining the tolerance of Nile tilapia juveniles to highly acidic rearing waters and the effects of water acidity on the quality of tank effluents. The experimental design consisted of four treatments with different water pH values (4.12 ± 0.84; 5.13 ± 0.74; 6.14 ± 0.64 and 8.06 ± 0.48), with five replicates each. No exchange of water was performed throughout the study, only water replenishment to maintain the initial level. Variables of water quality, soil, growth performance, metabolism and effluents were monitored for eight weeks. Despite the lower total ammonia nitrogen (TAN) concentration in the pH 8 tanks, their levels of non-ionized ammonia (NH3) were the highest ones. At the end, the lowest body weight of fish was... |
