Objective. Determine the nutritional values of ground (SCI) or extruded (SCE) canola seed and evaluate its use in the performance of piglets from 15 to 30 kg. Materials and methods. Two experimental diets with canola seed were evaluated in a digestibility trial. We used 15 barrows with an initial weight of 19.79±1.43kg, distributed in a completely randomized design. In the performance, four experimental diets were evaluated consisting of a diet with soybean oil added (RAS), one with the of addition of canola oil (RAC) and two oil-free; one with 11% SCI included and one with 6% SCE (RSCE) included. 40 commercial hybrid piglets were used that had 15.25±1.5kg initial body weight, randomly distributed, in four treatments and five replicates; two animals per experimental unit. Results. The digestible energy values for SCI and SCE were 4.197 kcal/kg and 5.234 kcal/kg, respectively. The extrusion process improved the digestibility coefficients. Piglets fed with RSCI showed less daily weight gain (DWG) and F:G ratio. Conclusion. Results suggest that SCE can be included in diets of piglets from 15 to 30 kg until 6% without negatively affecting performance.Key words: Animal performance, anti-nutritional factors, digestibility, economic viability (Source: AGROVOC).

Abstract Piglets experience a decline in body temperature immediately after birth, and both drying and warming piglets at birth reduces this. However, these interventions may have less effective at higher farrowing room temperatures. This study was carried out at a commercial facility to compare the effect of drying and/or warming piglets at birth on postnatal rectal temperature (RT) under relatively warm farrowing room temperatures (26.6 ± 2.09°C). Forty-five sows/litters were used in a completely randomized design to compare three Intervention Treatments (applied at birth): Control (no treatment); Warming (piglets placed in a plastic box under a heat lamp for 30 min); Drying+Warming (piglets dried with desiccant and warmed as above). Temperatures in the warming boxes over the study period averaged 37.7 ± 2.75°C. At birth, piglets were weighed; RT temperature was measured at 0, 10, 20, 30, 45, 60, 120, and 1440 min after birth. Blood samples were collected at 24 h after birth from a subsample of one piglet from each birth weight quartile within each litter to measure plasma immunocrit concentration. Data were analyzed using PROC MIXED of SAS with litter as the experimental unit; and piglet a subsample of litter. The model for analysis of piglet rectal temperature included fixed effects of treatment, measurement time (repeated measure), the interaction, and the random effect of sow. Compared to the Control, piglet RT were higher (P ≤ 0.05) for the Warming treatment between 10 and 60 min, and higher (P ≤ 0.05) for the Drying+Warming treatment between 10 and 120 min after birth. Rectal temperatures were higher (P ≤ 0.05) for the Drying+Warming than the Warming treatment between 20 and 120 min. Responses to drying and/or warming were greater for low birth weight piglets (&lt; 1.0 kg) than heavier littermates, but were generally less than observed in previous experiments with similar treatments carried out under cooler temperatures. Piglet immunocrit values were lower (P ≤ 0.05) for the Drying+Warming treatment compared to the other treatments, which were similar (P &gt; 0.05). Immunocrit values tended (P = 0.10) to be lower for light (&lt; 1.0 kg) compared to heavier birth weight piglets. In conclusion, drying and warming piglets at birth was more effective for reducing piglet RT decline after birth than warming alone, though the effect was less than observed in previous studies carried out under cooler farrowing room temperatures.

The objective of this work was to evaluate the productive performance of broccoli under different top-dressing organic fertilizations. The experiment was conducted under protected cultivation, in a completely randomized design with four replications, with two plants per experimental unit. Broccoli seedlings were produced in a commercial substrate in styrofoam trays. The seedlings were transplanted to plastic pots containing 10.0 L of substrate made up of subsoil and organic compost at the ratio of 3:1 (v/v), respectively, which is equivalent to about 20.0 t ha-1 of organic compost at planting. After seedling establishment, the top-dressing fertilization treatments were applied: gliricidia biomass associated or not with liquid biofertilizer of cattle manure to the soil and bokashi. Two control treatments were established: one with mineral fertilization recommended for the crop and the other without top-dressing fertilization. The broccoli production was evaluated (commercial standard). Plants that received mineral fertilizer were more productive, however, they were not significantly different (p>0.05), by Dunnet test, from the plants fertilized with 2.5 t ha-1 gliricidiabiomass (dry mass) associated with liquid biofertilizer (2.0 L m-2) applied to soil. Top-dressing fertilizations with only gliricidia, at 2.5 and 5.0 t ha-1 of biomass (dry mass), resulted in no significant increase in production of broccoli inflorescence. The use of bokashi in addition to gliricidia biomass and liquid biofertilizer reduced the efficiency of the fertilization compared with plants that received only gliricidia and liquid biofertilizer.

Performance Results

Two experiments were carried out to determine the nutritional value and to evaluate the performance and carcass traits in the growing-finishing pigs fed on two types of semipurified glycerin, which were made from vegetable oil (SPGV) and mixed of animal + vegetable oil (SPGM). In the digestibility trial (experiment I) 32 crossbreed barrows were used with initial body weight of 45.08 ± 4.11kg. It were used three levels of inclusion (6, 12 e 18%) of semipurified glycerin (SPGV and SPGM) in the basal diet. The metabolizable energy (ME) value of glycerin were estimated by regression of ME (kcal/kg) intake associated with glycerin vs. glycerin intake (kg). The values of ME (kcal/kg) obtained were: 2,731 for SPGV and 2,210 for SPGM. In experiment II, 72 pigs (30.08 ± 1.65 to 60.58 ± 3.57) in growing and (60.83 ± 2.63 to 93.79 ± 5.72) in finishing phase, were allotted in a completely randomized design in a 2 x 4 + 1 factorial scheme, with two types of semipurified glycerin (SPGV and SPGA), four inclusion levels (4; 8; 12 and 16%), eight experimental unit and a control diet containing no glycerin (0%). All pigs were slaughtered to evaluate the carcass traits. The performance results suggest that it is feasible to use up to 16% of both semipurified glycerins on growing and finishing pigs feeding, without impairing performance and carcass traits.
