RESUMO: Para avaliar a energia metabolizável (EMAn) da microalga (Spirulina platensis) para frangos de corte, foi realizado um ensaio de metabolismo em delineamento inteiramente casualizado, sendo 2 tratamentos (metodologias de determinação de energia - coleta total de excretas e indicador cinza insolúvel em ácido (CIA)) e 10 repetições de 14 aves. Ao final do período experimental os animas foram abatidos e foi feita a coleta do conteúdo ileal para determinação dos coeficientes de digestibilidade dos aminoácidos. Os valores de EMA da microalga determinado pelo método de coleta total (2865 kcal/kg MN) foi superior a determinada pelo indicador CIA (1995 kcal/kg MN). A EMAn também foi superior no método de coleta total (2493 kcal/kg MN) comparada ao indicador (1763 kcal/kg MN). Os CDEs médios dos aminoácidos essenciais foram de 79,99±3,5% e não essenciais de 78,52±4,2%. Conclui-se que a microalga S. platensis possui 2493 kcal/kg MN de EMAn e relevantes teores de aminoácidos digestíveis para frangos de corte. O uso do indicador CIA subestima a EMAn da microalga comparado ao método de coleta total (padrão). ABSTRACT: To evaluate apparent metabolizable energy (AMEn) of microalgae (Spirulina platensis) for broilers, a metabolism test was performed in a completely randomized design, with 2 treatments (energy determination methodologies - total excreta collection and acid insoluble ashes marker) and 10 replicates of 14 birds. At the end of the experimental period the animals were slaughtered and ileal content was collected to determine amino acid digestibility coefficients. AMEn values determined by the total collection method (2865 kcal/kg DM) were higher than those determined by AIA indicator (1995 kcal/kg DM). AMEn was also superior in the total collection method (2493 kcal/kg DM) compared to the indicator (1763 kcal/kg DM). The mean CDEs of the essential amino acids were 79.99 ± 3.5% and nonessential of 78.52 ± 4.2%. Microalgae S. platensis has 2493 kcal/kg DM of AMEn and relevant levels of digestible amino acids for broilers. The use of the AIA indicator underestimates the AMEn of the microalgae compared to the total collection method (standard).

The number of resistance genes in PI 89772 and PI 209332 conferring resistance to H. glycines race 3 is not well defined. Crosses of PI 89772 x 'Lee 68', PI 88788 x PI 89772, and 'Lee 68' x PI 209332 were made in the field and greenhouse. Several F1 and F2 families from each cross, 98 F3 families from cross PI 89772 x 'Lee 68', 74 F3 families from cross PI 88788 x PI 89772, and 80 F3 families from cross 'Lee 68' x PI 209332 were tested with an inbred line of H. glycines developed on PI 88788 to determine the leveI and inheritance of resistance. Approximately 8,000 individual plants growing in pots con- taining 200 cm3 of sterilized sand were inoculated with 4,000 eggs and J2/pot. Thirty days after inoculation the number of females that developed on each plant was determined. Cluster analysis revealed sets of families with a low mean number of females and low variance, intermediate means and high variance, and high means with a low variance, indicating F3 plants came from, respectively, homozygous resistant, heterozygous or segregating, and homozygous susceptible F2 plants. Thus, resistance classes were considered as quantitative parameters having different levels of resistance as opposed to only two classes, either resistant or susceptible. Chi-square analysis of segregation of phenotypic data indicated two genes confer resistance to face 3 of H. glycines. The three H. glycines-resistant parents have at least two genes that express resistance to H. glycines. One gene acts as a major gene (Rhg x) and the other a minor gene (Rhg y,) in conferring resistance of the parents PI 89772 (Rhg x1? Rhg x1?Rhg y1? Rhg y1?), PI 88788 (Rhg x2? Rhg x2? Rhg y2? Rhg y2?) and PI 209332 (Rhg x3? Rhg x3? Rhg y3? Rhg y3?) to H. glycines race 3. The same genes may occur in PI 209332 as in PI 89772, but support for this hypothesis must be obtained by studying the cross PI 209332 x PI 89772. The same major (Rhg x) and minor (Rhg y) genes occur in PI 89772 (Rhg x1? Rhg x1? Rhg y1? Rhg y1?) and PI 88788 (Rhg x2? Rhg x2? Rhg y2? Rhg y2?). The phenotypic ratios obtained in this research indicate that epistasis occurs between gene Rhg x and gene Rhg y. Results from this analysis indicated that the sensitivity of resistant genotypes to the environment is different from that of susceptible genotypes. In addition, a maternal effect was found for the inheritance of resistance of PI 88788 to H. glycines race 3, but not for PI 89772.
