Protease inclusion in plant- and animal-based broiler diets: Performance, digestibility and biometry of digestive organs

  • 2020
  • Issue: 2
  • Volume: 50
D.P. Carvalho, N.S.M. Leandro, M.A. Andrade, H.F. de Oliveira, M.F. Pires, K.A. Teixeira, P.S. Assunção & J.H. Stringhini Page: 291 - 301

The addition of protease to broiler diets may complement the action of endogenous enzymes and improve protein digestibility. Here, the authors evaluated the effect of adding protease to broiler diets that contained animal-based meal on bird performance, digestibility, and biometry…

Effect of population structure and underlying magnitude of dominance genetic effects on the estimation of additive and dominance

  • 2002
  • Issue: 2
  • Volume: 32
D. Norris, I.L. Mao and R. J. Coetzee Page: 113 - 120

Five populations with varying percentages of animals in full-sib families were simulated. For each population, three combinations of additive and dominance genetic variances of different relative magnitudes were considered, thereby creating fifteen sub-populations. Constant residual variance was used in all…
