The control bedding was pine shavings (PS) in both experiments and all trials. The novel bedding, aGroChips (AC), is a chopped paper product made from cotton lint waste, gypsum, and old newsprint following a proprietary paper manufacturing process. In both experiments, hens and toms were reared according to typical industry techniques. In the first experiment, use of AC resulted in significantly (P < 0.05) heavier toms and hens. In the second, the toms brooded and reared on AC were significantly (P < 0.05) heavier than those brooded and reared on PS, whereas toms brooded on one bedding and then reared on the other were intermediate in weight. There were no differences in final cumulative FCR or carcass yield in either experiment. Three field trials were conducted with Large White commercial turkey hens in which the hens were brooded either on PS or AC, with both groups reared on PS. There was a mean increase of 0.2 kg in BW, a decrease (improvement) of 0.03 in FCR, and an increase of 3,200 kg per trial for AC-brooded birds (based on 16,000 hens placed per brooder house). A hard, dry litter crust was observed in the AC houses. With subsequent testing, further changes in the manufacturing process to create a hard, durable pellet may result in a more usable and useful bedding material.}, number={4}, journal={JOURNAL OF APPLIED POULTRY RESEARCH}, author={Grimes, J.

Ross 308 broiler breeder pullets and Ross 344 cockerels were placed sex-separate in a blackout growing house and fed standard starter and grower diets to 9 wk of age. At 10 wk of age, 4 treatments (A, B, C, D) were assigned to each of 4 floor pens of 68 pullets and 1 pen of 50 cockerels. From 10 to 21 wk, treatments A to D contained 0.37, 0.27, 0.27, and 0.17% NPP, respectively, with 300 phytase units (FTU)/kg of phytase added to treatments B and D. At 21 wk of age, birds were photostimulated and transferred to a two-thirds slat-litter breeder house with 16 pens of 60 pullets and 6 cockerels. A laying diet was fed from 22 to 64 wk and NPP levels of treatments A to D were adjusted to 0.37, 0.27, 0.19, and 0.09%, respectively, and phytase addition to treatments B and D was increased to 500 FTU/kg. Analysis of the litter from growing pens showed no effect on litter total P when phytase replaced 0.1% of NPP. However, decreasing the dietary NPP by 0.1% without phytase reduced the litter total P by 18%. Water-soluble P (WSP) and the WSP:total P ratio decreased when the grower dietary NPP level was reduced to 0.17% with added phytase and was correlated with litter moisture levels in growing pens. During the laying period, a reduction in NPP from 0.37 to 0.09% with added phytase reduced both the manure total P and WSP by 42%. Hen-day egg production was highest on the lowest NPP diet with phytase, but fertility decreased when the dietary NPP was reduced below 0.37%. Results showed that phytase inclusion in a broiler breeder laying diet at the expense of all added P from dicalcium phosphate reduced the manure total P and WSP concentrations by 42%, with no effect on the number of chicks produced per hen housed.}, number={2}, journal={POULTRY SCIENCE}, author={Plumstead, P.

Eight samples were obtained and evaluated for nutrient content so as to provide the nutritionist with a baseline of information with which to consider possible use of this ingredient. At the present time, there is considerable variation in the composition of tilapia meals from different sources. Nutrient composition ranged from: CP, 52.5 to 57.8%; TMEn, 2,374 to 3,269 kcal/kg; and Ca, 5.2 to 10.6%. As significant variation was noted in levels of most nutrients, confirmatory analysis on specific samples is recommended prior to general use in formulation.}, number={3}, journal={JOURNAL OF APPLIED POULTRY RESEARCH}, author={Dale, NM and Zumbado, M and Gernat, AG and Romo, G}, year={2004}, pages={370–372} }
