High Roughage System for Raising Calves Based on Early Development of Rumen Function. IX. Effect of Rumen Inoculations and Chlortetracycline on Rumen Function of Calves Fed High Roughage Pellets

Digestion of High Fibre Roughage in the Rumen of Sheep

The extent of digestion of high fibre spear grass (Heteropogon contortus) hay by sheep was examined to determine the factors which limit its utilization. The mean organic matter (OM) intake (22 g/kgu.'3/day) and digestibility (39%) were low and all animals were in negative energy and nitrogen balance. Mean retention time in the rumen for the liquid phase marker (Cr-EDTA) was long (17.9 hours) a...

Effect of roughage :Concentrate ratio on the rumen activity of sheep and goats

Influence of post-rumen supply of nutrients on rumen digesta load and voluntary intake of a roughage by sheep.

The effects of post-rumen supply of nutrients on the rumen digesta load and voluntary consumption of roughage by Border Leicester X Merino ram lambs was investigated. A chopped wheaten hay was offered to the ram lambs (n 24), whose nutrient intake was altered by infusing into the abomasum a liquid supplement, containing reconstituted cow's milk, sodium caseinate, minerals and vitamins, for a pe...
