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.

A considerable problem in the catfish larvae rearing is related to the first feeding. This study aimed to determine the larvae growth and the survival of silver catfish submitted to feeding with Artemia sp. in different time periods. The study was conducted in the Aquaculture Laboratory of the Universidade Estadual do Oeste do Paraná, with four treatments and five replications, constituted by feeding with Artemia sp. in 5, 10, 15 and 20 days, and after each period of time, by its replacement by ration. We used 200 larvae distributed into 20 aquariums, soon after the eggs hatched. The larvae were fed 4 times a day until apparent satiation for 30 days. The Artemia sp. feeding for 15 days provided the best results on weight gain, final length and survival.

This experiment was conducted to evaluate the use of different energy levels and amino acid recommendations on performance, carcass yield and intestinal morphometry of broilers from 42 to 57 days of age. We used 1,600 one-day old male broilers (Cobb 500) in a completely randomized design arranged in a 2x4 factorial scheme with 3,200 and 3,600 kcal ME/kg and four different feed programs. The metabolizable energy levels and the feed programs did not determine significant differences in carcass characteristics for choosing a level of energy or a feed program, thus the energy level and the recommendations of amino acids that determine the highest cost-benefit ratio should prevail. It was observed that 3,600 kcal ME/kg resulted in some improvement on performance and morphometry of the intestinal mucosa, also the fractioning of digestible amino acid requirements during two periods resulted in worse performance and intestinal villi height.
