“…This compares well with published values (calculated by difference) of 0.69-0.74 (Bhattacharya & Fontenot, 1966), 0.50 (Rankins et al, 1993) and 0.57-0.58 (Rude & Rankins, 1997). Similarly, the total tract apparent digestibility of OM ranged between 0.54 and 0.64, and compared well with reported OM digestibilities of 0.64 (Fontenot & Jurubescu, 1980), 0.44 and 0.47 (Patil et al, 1995), 0.56 and0.58 (Chaudhry et al, 1996) and 0.42-0.46 (Rossi et al, 1996). The apparent digestibility of N in litter was 0.72 in the present study.…”

“…The potential problems associated with the use of poultry manure or litter as a feedstuff have been investigated extensively. Many studies have emphasised that precautionary measures should be employed when feeding this product, which may be nutritionally unbalanced or pose a health-risk to the animal (Fontenot & Jurubescu, 1980;Fontenot, 1991;Rankins et al, 1993;Mavimbela et al, 1997;Ruffin & McCaskey, 1998).…”

The aim of this experiment was to determine the site and extent of digestion of nutrients in sheep fed broiler litter alone (100% litter treatment), broiler litter plus 7.5% sugarcane molasses (92.5% litter treatment) and broiler litter plus 15% molasses (85% litter treatment). Voluntary intake was increased by molasses, apparently due to an increased rate of passage of digesta through the digestive tract. This resulted in a shift in the site of disappearance of organic matter (OM) from the rumen towards the lower digestive tract. For the 100 and 92.5% litter treatments, 0.37 and 0.46 of dietary OM disappeared in the rumen respectively, compared to 0.21 for the 85% litter treatment, while 0.16, 0.08 and 0.35 of dietary OM disappeared in the small intestine for the 100, 92.5 and 85% litter diets respectively. In the case of the 85% litter treatment, 0.26 of dietary nitrogen (N) disappeared in the rumen and 0.45 in the small intestine, compared to 0.55 and 0.62 in the rumen and 0.18 and 0.11 in the small intestine for the 100 and 92.5% litter diets respectively. There were no differences between treatments for total tract apparent digestibility of N (0.73) and OM (0.65-0.73), rumen degradability of N (71-87%) or concentration of ammonia-N in rumen fluid (53 mg/100 ml). It was concluded that the addition of molasses might be advantageous when the intake of litter is restricted or when voluntary intake of litter is unacceptably low.

“…Ammonia N concentration in broiler litter was slightly lower than a n average of 14% in litter noted by Fontenot and Jurubescu (1980 Patil et al, 1993). Condensed tannin concentration in BS was considerably less than expected (Jansman, 1993), although condensed tannins were not detected in S. In situ dry matter and N disappearances for broiler litter were similar to results of Mandebvu et al (1995a,b), Park et al (1995) and Wang et al (1996).…”

“…Conditions in broiler litter deep-stacks include 20 to 30% moisture, a pH of 7 to 9 and temperature of 40 to 60C (Ruffin and McCaskey, 1990). Ammonia in broiler litter is approximately 14% of total nitrogen; uric acid initially contributes a greater proportion of total nitrogen (e.g., 30%; Fontenot and Jurubescu, 1980), although its concentration declines with conversion to urea and ammonia (Oltjen and Dinius, 1976).…”

“…The digestibility of some sources of broiler litter is similar to that of medium-quality hay (Fontenot and Jurubescu, 1980), although if digestibility of litter is relatively low, ruminant performance is determined by the degree to which feed intake is compensatory (Patil et al, 1995).…”
