The present work reports a quantitative analysis of the effects of postnatal protein undernutrition on the stomach and gut growth in chicks (Gallus domesticus) using the bivariate allometric method. Seventy newborn animals were divided into a control group (n=35) and an undernutrition group (n=35), during forty-two days. The control group was fed with industrial chow (20% protein). The undernutrition group was fed with restrict diet (8% protein). The weights of the stomach and gut were correlated with body weight by the linear allometric model Log Y = K Log X + Log b. The values (CG: Ksto = 0.771 and Kgut = 0.634; UG: Ksto = 0.903 and Kgut = 0.998) showed a negative allometry (K < 1) in both groups, however, the undernutrition group presented higher growth rate than the control group. The coefficients of correlation are very high (p < 0.001, Tables 2 and 3).Downloads
