| 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... |

| The present study assessed the effect of adding water and phytase to middling diets on digestibility, metabolism, performance, carcass characteristics, and the bone mineralization of growing and finishing pigs. For the digestibility trial, 16 pigs were distributed in randomized blocks, placed in digestibility cages following a 2 x 2 factorial design (dry and wet diets, with and without phytase). For the performance trial, 48 piglets were distributed into a complete randomized design. During the growing period, wet diets presented higher values for digestibility and energy metabolism. In the finishing stage, the addition of water to the feed caused a greater weight gain and interfered with the carcass length. The balance of the mineral matter and the... |

| The addition of 0; 5; 10 and 15% cassava bagasse, based on the dry matter of the total diet of crossbred Holstein v. Zebu cows, was evaluated on milk production and composition and on the impacts of diet costs. The animals, weighing an average of 478.5 kg, were in the middle third lactation period. Diet with 15% cassava bagasse provided a 13.2% increase in production when compared to control. Feed conversion had a quadratic effect with minimum point at 4.2% of cassava bagasse inclusion. Crude protein, the only milk component that changed, increased linearly with the inclusion of cassava bagasse levels. Treatment with 15% cassava bagasse caused a more effective operational cost (42.8% higher when compared to control) and the highest leveling point for milk... |

| Abstract The objective of this study was to estimate variance components for performance and carcass traits in a paternal broiler line. The (co)variance components were estimated by the restricted maximum likelihood method applied to the animal model, including the fixed effect of group (sex and hatch) and additive genetic and residual as random effects. Estimated heritability for performance traits ranged from 0.09 to 0.42. The genetic correlations between traits ranged from -0.50 to 0.97. The heritability estimates of feed intake, weight gain, and feed conversion from 35 to 41 days of age were of low magnitude. The genetic correlations among them were favorable to genetic selection. These results suggest that moderate genetic gain can be obtained to the... |

| 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,... |

| ABSTRACT A non-surgical sterilant (NSS) was used with the objective of assessing the zootechnical performance, carcass and meat quality, and hormone levels. 90 male piglets were selected with birthweights varying between 1.5kg to 2.0kg. The control group was constituted of 45 males castrated by the conventional surgical method, at the seventh day of age, and the treated group was constituted of 45 males castrated with NSS (active principle of zinc gluconate in the concentration of 26.2mg/mL associated to the dimethyl sulfoxide at 0.5%), with the application of the first dose on the seventh day of age and the second dose on the fourteenth day of age. The zootechnical assessments were carried out on the farm and consisted: weight gain in the periods per... |

| The effects of cashew nut shell liquid (CNSL) on growth performance, carcass yield, relative weight of internal organs and microbiology of digestive tract of broiler chickens were investigated. Five hundred and forty male broiler chicks at one day of age were arranged in a completely randomized design with six treatments and six repetitions with 15 broiler chicks each. The treatments were: control (T1 - without growth promoter virginiamycin and CNSL); inclusion levels of 0.10mL (T2), 0.20mL (T3), 0.30mL (T4) and 0.40mL (T5) of CNSL/kg of feed; and commercial promoter virginiamycin (T6). At 21 and 40 days of age, body weight, feed intake, feed conversion and viability of birds were similar in all treatments. Carcass yield was higher in the treatment with... |

| For confined animals, performance is improved when their diet is supplemented with a mineral mixture and protein energy. This study evaluated the effect of dietary supplementation on feedlot sheep on native pasture. Two experiments were conducted in sequence, with the animals constrained in one and animals confined to pasture in the other. The experiments were conducted with 32 Santa Ines lambs, with average initial weights of 16.8 and 19.9 kg for the constrained and pasture studies, respectively. In both experiments, the animals were offered the following supplements: Supplement 1 = 200 g of the concentrate without mineral mixture; Supplement 2 = 200 g of the concentrate with mineral mixture + Mn + Zn; Supplement 3 = 300 g of the concentrate with mineral... |

| In Tropical regions, the animal performance is often affected by climate conditions. This study aimed to evaluate covering materials in individual shelters, normally used to house dairy calves, and its influence on the calves physiology and performance. The design used was completely randomized, with a 2x3 factorial arrangement to compare the averages of 5% through the Tukey's test, i.e., both genders- and three types of covering in the shelters (Z - zinc; AC - asbestos cement; and WPAC - white-painted asbestos cement). Parameters evaluated included daily weight gain (DWG), dry matter intake (DMI), feed conversion (FC), rectal temperature (RT), and respiratory frequency (RF). Results showed significant differences (P < 0.05) among males (1.04kg/day) and... |

| ABSTRACT A total of 320 13-weeks-old pullets were weighed and randomly allocated to treatments comprised by four levels of crude glycerin (0, 3, 6 or 9%) and two levels of ME (metabolizable energy, difference of 100 kcal/kg) in the diets growing (14 to 17 weeks of age), pre-lay and pre-peak (low: 2750, 2800 and 2750 kcal/kg and high: 2850, 2900 and 2850 kcal/kg, respectively). During the study, body weight was registered until 30 weeks of age, feed intake, egg weight and egg-production for each repetition and for individual hens were measured every week. The information was analyzed through a completely randomized design with a 4x2 factorial arrangement. During the growing phase, hens that received low energy diets consumed more feed (p<0.05), gained... |

| There is no formal recommendation, regarding dietary concentration, when it comes to feeding distillers dried grains with solubles (DDGS) to young broilers. This study evaluated the effects of varying levels of DDGS in a diet to young broilers from 0 to 14d of age. Diets ranged from 0 to 32% DDGS concentration, with 8% increments. Increasing inclusion rate of DDGS led to decreased body weight gain (BWG), whereas mortality seemed to be linearly increased. However, there was an increase seen in feed conversion (FCR) in conjunction with the increase in DDGS in the diet. An inclusion level of 8% DDGS or less is recommended for starter diets for broiler chicks. |

| ABSTRACT A prolonged period without feed access negatively impacts the growth and development of poultry. This study evaluated the effect of early post-hatch feeding times on the growth and carcass performance of Mule ducks reared intensively in the tropics. A total of 48 Mule ducklings were obtained from a local hatchery and assigned in a completely randomized design to 4 treatments based on 4 feeding regimes, (T) as follows: T1 3hrs, T2 24hrs, T3 36hrs and T4 48hrs post-hatch. On day 1 the ducklings were individually weighed, followed by weekly weighing until harvest at 63 days. Feed and feed refusal was measured daily for a period of 63 days. At harvest the body weight at slaughter, eviscerated and hot carcass weight, as well as the initial pH and pH24... |

| The objective of this study was to evaluate performance, carcass dressing and gross profit margin of lambs of different genotypes finished in feedlot with diets containing two levels of energy (2.40 Mcal/kg dry matter - DM or 2.90 Mcal/kg DM). Fifty-four non-castrated lambs of the following genotypes were used: Santa Inês, F1 Dorper × Santa Inês and F1 Santa Inês × undefined breed at approximately 150 d of age averaging 22.6 kg of live body weight. Lambs subjected to the diet containing 2.90 Mcal/kg DM stayed in feedlot for a shorter period of time. Moreover, they showed lower intake of dry matter and water in addition to greater daily weight gain and corporal score. There was interaction of feed conversion, carcass dressing yield and gross profit margin.... |
