“…Using increasing levels of P in diets containing 0.30 or 0.70% calcium, Erickson et al (1999) found no interactions between Ca and P levels on performance as Ca:P ratios declined from 5:1 to 1:1. Performance was not affected with Ca:P ratios as low as 1:1 in the trials of Ricketts et al (1970).…”

“…Dietary calcium in excess of requirements has improved gain or feed efficiency in some trials (Huntington 1983;Brink et al 1984;Bock et al 1991). However, excess levels of limestone have reduced DMI and even gains in other trials (Russel et al 1980;Hironaka 1988;Erickson et al 1999), possibly through reduced OM digestion resulting from increased rumen fluid dilution rates (Goetsch and Owens 1985).…”

. 2008. Effect of dried distillers' grains from wheat on diet digestibility and performance in feedlot cattle. Can. J. Anim. Sci. 88: 659Á665. In a 55-d backgrounding period, 120 British cross heifers (312920 kg) received diets containing 55% barley silage, 5% supplement and 0 (n 024), 20 (n 024), or 40% (n 072) wheat distillers' dried grains with solubles (DDGS). The remainder of the diet was steam-rolled barley. Replacing half (20%) or all (40%) of the barley with DDGS did not affect dry matter intake (DMI) (P00.61), average daily gain (ADG) (P00.86), or gain:feed (P00.94), indicating the energy content of DDGS is similar to that of barley when included in backgrounding diets. During a 133-d finishing period, DDGS were included at 0, 20, 40, or 60% of diet dry matter (DM) or at 60% plus additional calcium, provided as 1% limestone (n 024). Additional calcium did not (P!0.1) affect DMI, ADG, or gain:feed. Increasing levels of DDGS linearly increased (P00.001) DMI and reduced (P00.04) gain:feed and diet NEg content (P00.001), but had no effect on ADG (P00.20). Feeding 60% DDGS reduced (PB0.01) DM digestibility as compared with the control. Wheat DDGS has similar feeding value as barley when included at 20% of diet DM, but digestibility and energy content decline with higher levels of inclusion.Key words: Beef, digestibility, distillers' dried grains, wheat Gibb, D.

Remplacer la moitie´(20 %) ou la totalite´(40 %) de l'orge par des DDGS n'affecte pas l'ingestion de matie`re se`che (P00,61), le gain quotidien moyen (P00,86) ni le ratio gain/aliment (P00,94), signe que les DDGS renferment autant d'e´nergie que l'orge quand on s'en sert pour la semi-finition.

“…In a similar experiment with yearling steers (BW = 385 kg), supplementation of P did not improve performance (Erickson et al, 1999). Dietary P fed to yearlings in that study ranged from 0.14 to 0.34% of diet DM, with individual intakes of 16 to 36 g/d equating to a range of 71 to 162% of NRC recommendations (Erickson et al, 1999).…”

“…However, P requirements are not well established for beef feedlot cattle weighing between 270 and 600 kg. Erickson et al (1999) evaluated P requirements of yearling steers (380 kg) with typical feedlot gains (> 1.5 kg/d) and concluded that the requirement 1690 matter intake and ADG did not change linearly (P > 0.86) or quadratically (P > 0.28) due to P treatment. Feed efficiency was not influenced (P > 0.30) by P treatment and averaged 0.169.…”

Dietary P supplied to feedlot cattle is important because an inadequate supply will compromise performance, whereas excess P may harm the environment. However, P requirements of feedlot cattle are not well documented. Therefore, 45 steer calves (265.2 ± 16.6 kg) were individually fed to determine the P required for gain and bone integrity over a 204-d finishing period. The basal diet consisted of 33.5% highmoisture corn, 30% brewers grits, 20% corn bran, 7.5% cottonseed hulls, 3% tallow, and 6% supplement. Treatments consisted of 0.16 (no supplemental inorganic P), 0.22, 0.28, 0.34, and 0.40% P (DM basis). Supplemental P was provided by monosodium phosphate top-dressed to the daily feed allotment. Blood was sampled every 56 d to assess P status. At slaughter, phalanx and metacarpal bones were collected from the front leg to determine bone ash and assess P resorption from bone. Dry
