Effects Of Dietary Fiber And Protein Concentration On Growth, Feed Efficiency, Visceral Organ Weights And Large Intestine Microbial Populations Of Swine, James S. Dickson, Friday O. I. Anugwa, Vincent H. Varel, Wilson G. Pond, Lennart P. Krook

James S. Dickson

Finishing barrows (average initial weight 55.5 ±2.4 kg) were used to determine the effects of high dietary fiber or protein on performance, visceral organ weights and large intestine microbial populations and to monitor the duration of regression of swine visceral organ mass and microbial populations to control values following trans fer from the high fiber or high protein diet to the control diet Four pigs from each diet were killed on d 17, 34, 48 and 66. From d 34 until slaughter 14 and 32 d later, all remaining pigs were fed the control diet ad libitum. High fiber resulted …
