Abstract

A study determined if dietary corn dried distillers grains with solubles (DDGS), canola meal (CM), or chloride (Cl) could adversely affect the performance and litter moisture of turkeys. A total of 1,089 Nicholas toms were used in a study during 2 to 14 wk of age. The poults were randomized into 99 pens (11 poults/pen) with number reduced to 10/pen at 8 wk. The factorial arrangement consisted of 3 diet sets [cornsoy (CS), CS + 20% DDGS, CS + 20% DDGS + 10% canola meal] and 3 Cl levels (0.22, 0.32, 0.42%), making 9 treatments distributed in 11 replicate blocks. Diets were formulated to be isocaloric with similar levels of digestible amino acids for each of 4 feeding phases. The dietary electrolyte balance varied with diet set and age period and ranged from 351 to 181 mEq/kg of diet (Na+ + K+ - Cl-) or 184 to -29 mEq/kg (Na+ + K+) - (Cl- + S2-). Individual BW and pen feed residues were measured at each phase. Samples of litter were collected at 11 and 14 wk for measuring moisture. During 2 to 14 wk, no differences were observed in BW and ADG attributable to diet (P < 0.05). Birds fed diets containing DDGS or with CM consumed 6.0% more ADFI (P > 0.05). No differences were found for Cl or diet × Cl interaction for BW, ADG, or ADFI. The feed conversion ratio (FCR) was higher (P > 0.05) for birds fed diets containing DDGS or CM. A diet × Cl interaction was found for FCR during 8 to 14 wk; increasing Cl over 0.22% significantly increased the FCR by 3.0% only in diets containing DDGS with CM. Litter moisture was increased in diets containing DDGS or with CM, and by increased Cl. Including S in dietary electrolyte balance resulted in a better albeit weak correlation with ADG during 2 to 5 wk (-0.51 vs. -0.36) and FCR during 11 to 14 wk (-0.36 vs. -0.21). Due to the detrimental effect on FCR, high Cl should be avoided with DDGS and CM in turkey grower diets.
