“…Because in our investigation there was no effect in N retention between treatments, this could mean that the silages studied were equally effective as N sources for growing lambs. Rude & Rankins (1993) made silage with PL and corn forage, Johnson grass, sorghum and Bermuda grass, and found higher N retention and digestibility of DM, OM, and NDF when mixing corn forage and PL. Jakhmola et al (1984) studied cattle waste mixed with green maize and wheat bhoosa enriched with urea and MOL prior to ensiling (wastelage).…”

The objective of this study was to evaluate the nutritive value of maize stover silage diets containing pig excreta (PE), poultry litter (PL) or urea as nitrogen (N) sources, and sugarcane molasses (MOL) or bakery by-products (BBP) as energy sources. The study was designed as a 6 × 6 Latin square with six ruminal cannulated Hampshire rams (56 ± 5.7 kg body weight) in a 3 × 2 factorial arrangement of treatments. The quality of silages was good because of acceptable pH (4.1), texture and odour. Gas production was higher for diets with silage containing PL than that containing PE (287 vs. 269 mL/g DM). The fermentation rate of diets with MOL was higher than with BBP (0.07 vs. 0.05/h). The in vitro degradation, feed intake and N excretion of diets that contained PL were higher than with PE silage. Feed intake for diets with silage that contained BBP and PL or PE was lower than that containing MOL. Rumen pH was increased in lambs fed diets with silage that contained urea (6.38) or PL (6.25), compared with lambs fed diets containing PE silage (6.04). Dry matter (DM) and organic matter (OM) disappearances were higher for diets with silage containing PL compared with those containing PE or urea (650 vs. 606 and 594 g/g DM; 620 vs. 574 and 594 g/g OM, respectively). The N retention and total tract digestion were similar for all treatments. It was concluded that diets with PL and MOL silage had higher nutritive values than those containing PE or urea.

“…Although litter stacking method had no significant effect on N retention (P > 0-05), lambs given covered litter retained more N. In fact, these lambs retained proportionately 0-35 more N than lambs given uncovered litter (a greater difference than for N apparent digestibility). Part of this difference may be explainable by the fact, if the diets were consumed shortly before bleeding, that broiler litter contains proportionately approximately 0-36 non-protein N (Rude and Rankins, 1993) while urea is 1-0 non-protein N. However, all lambs were bled prior to feeding. Although one would assume greater serum urea values in animals excreting more urinary N, this was not observed in the present study.…”

Nitrogen and energy metabolism and serum constituents in lambs given broiler poultry litter processed by three deep-stacking methods

1994

Poultry litter has been used as an economical nitrogen (N) source in ruminant diets. However, litter must be processed to eliminate pathogens. Broiler poultry litter was processed by three different deep-stack methods: (1) uncovered, (2) covered with 0-1524 mm clear polyethylene, and (3) aerated by placing perforated pipe 1 m apart within the stack. Stack temperature was measured for 28 days. The litter was used to formulate experimental diets (186 g litter per kg), while the control diet contained urea as the N source. All diets contained 100 g/kg cottonseed hulls, 16 to 17 g/kg limestone, varying amounts of cracked maize and added retinol. The control diet contained 131 g/kg crude protein (CP) while the litter diets contained 125 g/kg CP. The diets were offered to 16 crossbred wether lambs (37 (s.e. 6-1) kg) in individual metabolism crates for 16 days. Blood was collected at the initiation and termination of the trial. Covering litter with plastic decreased temperature ivithin the stack fP < 0-05). Maximum temperature for the uncovered, covered and aerated stacks was: 68°C, 57°C and 72°C, respectively. Dry-matter intake and dry matter, energy and neutral-detergent fibre apparent digestibilities were not different (P > 0-05) among the diets. Apparent digestibility for N was less (P < 0-05) in lambs given uncovered and aerated litter than in those given the control diet. However, N apparent digestibility in lambs given covered litter was not different from that of those given the control diet. Gross energy and N retention of the four diets were not different fP > 0-05). Covering deep-stacked broiler poultry litter improved N digestibility by proportionately 0-15 compared with uncovered litter. Serum chloride was decreased while serum urea was increased (P < 0-05) in sheep consuming the litter-containing diets. Deep-stacked broiler litter should be covered in an air-tight manner in order to maximize its nutritive value.
