Effeet of Low Protein Diet on Grow.th Performanee and Diar）hea Rate in Growing Pigs
Abstract：This experiment was conducted to study the effect of low protein diet on growth performance and diarrhea rate in growing pigs. Sixty-six crossed-bred （Duroc ×Landrace ×Yorkshine） pigs, weighing an average of 16 kg, were randomly assigned to two dietary treatments with three replicates and eleven pigs with each pen. The groups received basic diet and trial diet respectively. The basic diets were formulated in accordance with NRC （Nutrient requirements of swine）（1998） nutritional requirements, while the trial diet protein level was 0.38% lower than the protein requirement of NRC（1998）, with adding essential amino acid. The feeding trial lasted for 30 days. The results showed that low protein diet raised the daily gain （ADG） and reduced F/G （Feed/Gain） significantly （P〈0.05）, but there were no significant effect on diarrhea rate （P〉0.05）. These results indicated that low protein diet can improve the performance of pigs and the utilization ratio of forage.
