A.S. Series 75-59
Research conducted during the past several years has shown that dietary protein could be reduced in gestation diets without affecting number or size of pigs farrowed. A limited amount of research has also indicated that the protein requirement during lactation may not be as great as previously recommended. However, data are limited on the long time effects during successive reproductive periods, particularly when low protein diets are fed during both the gestation and lactation periods. The North Central Swine Nutrition Research Committee agreed that this was an area where more information was needed and a cooperative project was initiated to study the effect of level of protein in gestation and lactation diets over successive reproductive periods. The results reported herein are from a study at the South Dakota Agricultural Experiment Station. These results will be combined with those from other states for an overall analysis of the data.
