The experiments were conducted to study the effects of dietary energy(DE),crude protein(CP),calcium(Ca) and phosphorus(P) on the growth performance and blood biochemical parameters of growth Yorkshire newly imported from USA.The orthogonal 4×3 factorial trial was used and 9 kinds of diets were designed to determine the requirements of DE,CP,Ca and P of newly imported Yorkshire from USA.The results showed that the energy level significantly effected on the average daily gain(P0.05),and the DE,CP,Ca and P levels extremely and significantly effected on DE digestion(P0.01).The CP,Ca and P levels extremely and significantly effected on CP and CF digestion too(P0.01).Similarly,the energy level extremely and significantly effected on P(digestion,and the DE,CP and Ca levels extremely and significantly effected on EE digestion.The energy level significantly effected on T-Cho and TG,and the CP level significantly effected on Alb.Our results indicate that the best nutritional level of Yorkshire diet should contain 14.23 kJ/kg DE,21.5% CP,0.8% Ca and 0.8% P,respectively.
