The experiment was carried out with the objective of evaluating the ileal endogenous losses of amino acids in function of different fiber levels inclusion in a free protein diet. Were used eight crossbreed swine, castrated males, averaging 50.17 ± 4.10 kg initial weight, submitted previously to the simple T canula surgery implantation, allotted to a randomized blocks design, with four treatments, four replicates and one animal per experimental unit. The treatments consisted in a free protein diet with four levels of rice husks inclusion, that provided levels of 1.00, 2.00, 3.00, and 4.00% of crude fiber and/or 1.82, 3.64, 5.46, and 7.28% neutral detergent fiber. Contents of dry matter, crude protein, chromium and amino acids of the ilel samples and experimental rations were determined. It was observed a great variation among the amino acids endogenous losses, within treatments. It was concluded that, among the studied amino acids, just the glycine did not show significant effect to the fiber levels inclusion in the free protein diet, and there was an increase in the endogenous losses of the other amino acids, as the fiber levels in the diet increased.

ABSTRACT A study was carried out to evaluate the particlesize of the corn, the performance and electric powerconsumption of hammermills and to determine thehammermills characteristics that influence the averagegeometric diameter of the particles. To determine the cornparticle size predictors and the hammermills characteristics,the independent parameters were considered using the“Backward” statistical process to obtain the equations. Theequation to estimate the average geometric diameter thatshowed the higher R 2 (0.85) was: 330.59 + 494.284TX –11.844PM + 113.746DP – 0.186ATP. The grinding ratevariation and the electric power consumption, of thehammermills, can be due to the differences among thecharacteristics of the mills, the wasting due to the use and ofthe potency of the motors of the mills. It was ended that thegrinding rate and the diameter of the hole sieves’ showed apositive relationship with the average geometric diameter,and the engine power and the total sives’ area showed anegative relationship.

The objectives of this study were to evaluate the chemical composition and energetic values of diferent high moisture corn grain silages (HMCGS) for swine, and to adjust prediction equations for digestible (DE) and metabolizable (ME) energy based on the chemical composition. The treatments consisted of eight diferent high moisture corn grain silages that substitued 30.0% of the basal diet. The analysis of DM, CP, EE, ADF, NDF, Ca and P were performed for the refered silages. To determine the energetic values 36 swines were used, alloted in a randomized blocks design with four replicates. The values of DE and ME of the HMCGS varied from 3494 to 3701 kcal/kg of DM and from 3392 to 3613 kcal/kg of DM, respectively. The equations adjusted to predict the DE and ME values of the HMCGS did not show a good adjustment, showing low determination coefficients, and the fat content showed a positive relation and the CF a negative one, for the energetic values studied.

Neste Trabalho, objetivou-se avaliar o efeito da suplementacao de dietas contendo probiotico e simbiotico sobre o desempenho de leitoes dos 21 aos 49 dias, microbiota intestinal e peso dos orgaos. Foram utilizados 120 leitoes mesticos desmamados aos 21 dias de idade, distribuidos em um delineamento de blocos casualizados, com tres tratamentos (antibiotico, probiotico e simbiotico) e cinco repeticoes, sendo a unidade experimental representada pela baia, onde foram alojados oito leitoes. No periodo de 21 a 35 dias de idade, nao se observou diferenca (P>0,05) no desempenho. No periodo de 36 ate os 49 dias, pode-se observar maior ganho diario de peso (P 0,05) pelos tratamentos. O uso de probiotico e simbiotico nas racoes foi efetivo para leitoes dos 21 aos 35 dias de idade para as variaveis de desempenho e contagem de coliformes no ileo e colon, e dos 36 aos 49 dias de idade o uso de antibiotico foi melhor em relacao as variaveis de desempenho.
