| Abstract: The objective of this work was to evaluate the performance of young Nellore bulls and of young dual-purpose dairy bulls fed proportions of 'Mulato II' grass silage (400 and 100 g kg-1), in diets with high levels of concentrate, as well as to evaluate the cost of this feed. Sixteen young Nellore bulls and 16 young dairy crossbred bulls were used, with initial average weight of 380.69±10.45 and 376.94±17.16 kg, respectively, and average initial age of 24 months. A completely randomized experimental design was carried out in a 2x2 factorial arrangement. The highest silage proportion caused a 13% increase in dry matter intake (percentage of body weight) and a 19.7% decrease in dry matter digestibility of the diet, but it did not alter the intake of... |

| ABSTRACT The objective of this study was to evaluate the production performance of feedlot cattle fed diets containing chopped sugarcane ratios (580 or 380 g/kg of diet dry matter) as roughage and levels of inclusion of babassu mesocarp bran (BMB; 420 to 620 g/kg of concentrate dry matter). Twenty-four young Nellore bulls with 321±23 kg initial body weight, at 22 months of age, were used in a completely randomized experimental design with treatments in a 2 × 2 factorial arrangement and six replicates. Dry matter intake (21.71 g/kg of body weight), average daily gain (1.46 kg/day), and cold carcass weight (232.59 kg) were not changed by proportion of sugarcane or BMB level. The proportions of sugarcane and BMB levels did not change the apparent... |

| The relation between temperament with performance and meat quality was determined in 79 Charolais × Nellore steers kept in feedlot. Temperament was evaluated according to exit velocity, scale composite score and flight distance four times in the finishing phase, along with body weight, intake and feed conversion measures. Cattle were classified as calm, intermediate and excited according to exit velocity measures at the beginning of the trial. Excited cattle presented larger values for composite score and flight distance. Irrespective of genotype, excited cattle presented lower average daily gain, dry matter intake and worse feed conversion. Temperament categories did not affect most of beef quality traits, except for calm Bos indicus steers, which... |

| The demand for alternative food sources is currently in evidence in the world and, therefore, the culture of animal species considered not conventional makes this theme relevant and appropriate. In the present study, the species Pomacea lineata and Pomacea bridgesii, each with three stowage densities (0.5 [T1], 1 [T2], and 1.5 [T3] animal/L), were tested. They were analyzed regarding growth rate, weight gain, final biomass, feed conversion and percentage of survival. There was not any statistically significant difference between the different densities for both species. The final average weight in the three waterworks did not differ significantly in P. bridgesii. In P. lineata, T1 (22.3 ± 1.80g) was significantly higher than T2 and T3. On the other hand,... |

| Seventy-seven ewes were randomly divided into groups according to parturition season and suckling mode [Rainy season: continuous (n=14) and controlled (n=13); Dry season: continuous (n=25) and controlled (n=25)]. The controlled suckling mode, in both seasons, resulted in a decrease in variables, intervals between parturition and first estrus (reduction of 27.11 and 11.46 days for rainy and dry season, respectively; P<0.05) and between parturition and estrus of conception (reduction of 12.81 and 13.58 days, for rainy and dry season, respectively; P<0.05). As to the lambs, the weight gain was higher in animals subjected to controlled suckling in relation to continuous, especially when lambing occurred in the rainy season (17.83±0.56 vs. 13.95±0.52kg... |

| Thirty crossbred two-year-old steers, kept on pasture of Braquiaria decumbens, were used in two different experiments of 90 days each. In the first experiment, the steers were randomly assigned in five groups of six steers each to verify the influence of different percentages of sodium chloride (SC) in mineral mix (MM) containing essential macro and microelements (A - 100% SC; B - 80% SC/20% MM; C - 60% SC/40% MM; D - 40% SC/ 60 MM and E - 20% SCl/80 MM) on the consumption of the mineral supplement and the weight gain. In the second experiment, the same steers were reassigned to three groups of 10 animals each to study the effect of mineral salt (40% SC/60% MM) offered loose, partially blocked or as a hard block on the mineral consumption and weight gain.... |

| This study aimed to investigate the influence of calf genetic group on the performance of Nellore lactating cows. The variables studied included milk ingestion, pasture intake, calf weight gain and cow body weight. A total of 13 Nellore calves and 8 crossbred Simental × Nellore calves were used, all born from Nellore mothers. During the experimental period of 210 days, calves were weighted at birth and at 30-day intervals, whereas cows were weighed every 14 days. Milk intake was estimated using the weigh-suckle-weigh method. Pasture intake was determined 6, 12, and 24 weeks after birth by using chromic oxide as an external marker and indigestible acid detergent fiber as an internal marker. Average weight of crossbred calves was 10.1 kg and their milk... |

| The aim of the present study was to determine the effects of waterborne un-ionized ammonia (NH3) on the survival and growth of silver catfish (Rhamdia quelen). Juveniles were exposed to 0.10, 0.22, and 0.42mg L-1 NH3 at pH 8.2 for 45 days. After 15 days, a significant mortality rate (33%) was observed in the fish exposed to 0.42mg L-1 NH3. After 20 days, 23% and 43% mortality (both significant) was observed in fish exposed to 0.22 and 0.42mg L-1 NH3, respectively. A significant negative relationship between survival, length, daily weight gain, standard growth rate, and biomass of juveniles of silver catfish per tank with waterborne NH3 levels was found at the end of the experiment. The resulting survival and waterborne NH3 relationship indicated that, to... |
