  • Three sheep fitted with rumen cannulae and abomasal cannulae were given daily 750 g (DM) of three diets consisting of straw-manure silage and barley mixture in the ratios of 75:25, 50:50 and 25:75. As the proportion of barley in the diet increased, there was an increase in the amount of OM apparently digested in the rumen and thole tract (P<.01). But ADF digestion was decreased. For the 25:75 diet the $NH_3-N$ content in the rumen showed the highest value, but the total VFA was the lowest. The rumen volume and dilution rate increased with increasing ratio of silage in diets. There were no significant differences between diets in abomasal NAN flow, and the bacterial-N for the 25:75 diet was 7.3 g N as compared with 9.2-9.6 g N for the other diets (P<.01). Rates of bacterial nitrogen synthesis in the rumen were 30.5, 24.1 and 14.9 g N per Kg OM apparently digested in the rumen for the 75:25, 50:50 and 25:75 diets, respectively.

  • This studies were conducted to investigated the feeding effects of extruded broiler manure(BMERF) mixture and swine manure(SFERF) mixture on laying performance and egg qualify of laying hens. As a experimental feed, broiler manure, corn and tapioca were mixed in 50, 30 and $20\%$ to use for treated extrusion feed(BMERF, Exp. 1) and food waste(FW), swine manure and com were also mixed in 40, 40 and $20\%$ to use it(SFERF, Exp. 2) and implemented during 12 weeks, four replication and 30 chick of each treatment. The nutritional ingredients(protein, energy and calcium contents) of food waste, broiler manure and swine manure had been significantly improved(p<0.05) when handling extrusion. In the Exp. 1, the feed intake was much higher BMERF $40\%$ and BMERF $20\%$ than control and BMERF $10\%(p<0.05)$, the egg production of control, BMERF $10\%$ and BMERF $20\%$ were not significantly difference(p>0.05), but BMERF $40\%$ was significantly lower(p<0.05). The feed efficiency of control and BMERF $10\%$ were not significantly difference(p>0.05), but BMERF $20\%$ and BMERF $40\%$ were significantly lower(p<0.05). York color, White height and Haugh unit did not affected by BMERF additive. In the Exp. 2, the feed intake of control, FW $20\%$, SFERF $10\%$ and SFERF $20\%$ were not significantly difference(p<0.05), but FW $40\%$ and SFERF $40\%$ were significantly higher(p<0.05). The egg production of SFERF $10\%$ and SFERF $20\%$ were not significantly difference(p>0.05) with control, but FW $20\%$, FW $40\%$ and SFERF $40\%$ were significantly lower(p<0.05). The feed efficiency was similar tendency to the egg production, however, the egg weight, york color, white height and haugh unit were not significantly difference among each treatments(p>0.05).
