Maize-meat meal and maize-meat and bone meal diets were supplemented with dl-tryptophan, l-lysine or a mineral-vitamin-antibiotic (MVA) premix and fed to pigs during the 1s to 45 kg growth phase. Diets were offered at an estimated 145 kcal of digestible energy and 7g crude protein per kg liveweight per day. The basal maize-meat meal diet produced poor growth and feed conversion and the combined addition of all three supplements increased growth by 46 per cent, feed conversion by 21 per cent, and lean in the ham by 4.7 per cent. This effect resulted from responses to dl-tryptophan, the MVA and an interaction between dl-tryptophan and l-lysine, with l-lysine depressing gain and feed conversion in the absence of dl- tryptophan and increasing gain, feed conversion, and lean in the ham in its presence. The basal maize-meat and bone meal diet also produced poor growth and feed conversion, and the combined addition of all three supplements resulted in an 82 per cent increase in growth, a 35 per cent increase in feed conversion, and a 3.3 per cent increase in lean in the ham. Both dl-tryptophan and MYA separately increased growth and feed conversion and combined they had an even greater effect. The l-lysine increased feed conversion and lean in the ham. The l-lysine also increased growth rates on the dl-tryptophan supplemented diets, but this effect was not significant (P>0.05).

Dietary Protein Level

The effect of dietary protein content (25, 60, 95, 130, 165 and 200 g crude protein (N × 6.25)/kg diet) on the apparent and true ileal digestibilities of N and amino acids in meat-and-bone meal given to the growing rat was investigated. Semi-synthetic diets in which meat-and-bone meal was the sole protein source were given to 180 g body-weight rats for 14 d. On the fourteenth day the rats were fed and then killed 4 h after the start of feeding and digesta were sampled from the terminal 200 mm ileum. Endogenous amino acid excretion was determined for eighteen rats given an enzymically hydrolysed casein (EHC)-based diet and with subsequent treatment of the digesta using ultrafiltration. The EHC-fed rats were killed 3 h after the start of feeding and digesta were collected from the terminal 200 mm ileum. True ileal digestibility values determined with reference to Cr as a marker were higher than the corresponding apparent estimates. Apparent digestibility values of N and amino acids increased significantly (P < 0.001) with increasing dietary protein level; however, dietary protein content had no significant (P > 0.05) effect on the true ileal digestibilities of N and amino acids. The mean apparent ileal digestibility of N in meat-and-bone meal ranged from 65.6 to 75.3%. The corresponding range for the true ileal digestibility of N was 76.9 to 78.2%. True ileal digestibility, unlike apparent digestibility, appears to be independent of dietary protein level and may allow feed ingredients to be compared accurately even if they are ingested in different quantities.
