One indirect approach to predict the disinfection by-product (DBP) formation potential for a given water source is by evaluation of the kinetic behavior of free chlorine in the liquid phase and chlorine demand determination for different operation conditions of the chlorination process. The objective of this work was to evaluate the kinetic behavior of free chlorine in water or a number of different raw water sources, as well as to investigate the impact of the coagulation process on chlorine demand reduction and DBP formation. It was observed that the higher the total organic carbon (TOC) removal efficiency through coagulation, the lower the liquid phase chlorine demand. Regarding trihalomethane (THM) formation, a ratio of 28 ug/L formed per mg/L of applied chlorine was observed for the waters employed in the experimental investigation.

The study was carried out to evaluate the inclusion of increasing levels (0, 3,0 and 6.0%) of fish silage (SSFP), in the ration. The parameters studied were urea, uric acid, total protein, triglycerides, total cholesterol and lipoproteins (LDL, HDL and VLDL). Eighteen female piglets Moura weighting and crossbred Duroc x Moura, were used with 24,0± 3,0 kg in average weight and 90 days of age and eighteen male pigs Moura and crossbred Duroc x Moura, with 31,5±5,0 kg in average weight and 70 days of age in a randomized design with 3 treatments. The results showed no effect to the addition up to 6,0% of SSPF in the swine diet neither for in growth, nor to the serum parameters, even if had been found alteratum on the urea plasmatic concentrations experiments. All the parameters was closed to the normal value recommended in the literature.

The aim of this work was to evaluate the introduction of 8% grains and by-products (meal or cake) of canola in the diets of lambs. To evaluate quantitative carcass characteristics, 24 Santa Ines lambs were used in a completely randomized design. Diets with averages of 15.4% of CP in DM and 80.2% of TDN were composed for 40% Tifton hay and 60% concentrate based on corn grain, soybean meal, whole grain canola, canola meal, canola cake and mineral mixture. The use of whole grains and by-products of canola in the diet of lambs finished in feedlot did not influence (p > 0.05) quantitative carcass characteristics. For cut dressing in relation to the CCW, no effect was observed for the analyzed variables among treatments. It was concluded that the introduction of grains and by-products of canola allow for satisfactory results, and could be recommended in the formulations of lamb diets.
