| Abstract: | In an effort to determine if mature collagen turns over and if crosslinking can be altered, 14 mature female sheep were fed 2 or 4 g of BAPN per day for 20, 40 or 60 days. At completion of each treatment interval, the ewes were slaughtered and muscle samples (LD, BF, ST), achilles tendon and lumbo-dorsal fascia were removed. Collagen solubilities as determined by the heat-labile extraction procedure were affected (P<.05) by dosage and time on BAPN. The solubilities of control LD and ST samples were approximately 3% lower than solubilities from 60-day BAPN treated samples. Collagenase solubility for control LD samples averaged 4.1%; that for 60-day BAPN treated samples was 29.5%. The effect of BAPN on collagen from the lumbo-dorsal fascia and the achilles tendon was less pronounced, and no differences (P<.05) were observed due to dose or time on BAPN. The concentration of glucosamine in LD samples was not affected by time on BAPN. Tenderness of LD samples, as determined by WBS, was not increased by BAPN dosage or time. The effects of the three compounds, EDTA, curare, succinylcholine and of EDTA plus succinylcholine on the rigor shortening of pre-rigor sternomandibularis muscles were studied. EDTA significantly (P<.05) reduced the extent of muscle shortening.. |
