“…To decrease nutrient excesses and production costs, broiler producers often omit vitamin and(or) trace mineral premixes during the last week before slaughter. University data suggest no negative effects on growth performance or carcass characteristics when this production strategy is employed (Waldroup et al, 1968;Skinner et al, 1992c;Deyhim and Teeter, 1993). Furthermore, Skinner et al (1992a) and Chen and Moran (1994) reported that withdrawal of the inorganic P source during the last week before slaughter had no effect on growth performance or carcass characteristics of broilers.…”

Three experiments were conducted to determine the effects of omitting vitamin and trace mineral premixes and(or) reducing inorganic phosphorus additions to finishing diets on growth performance, carcass characteristics, and muscle quality in pigs. In Exp. 1, a corn-soybean meal-based diet (.70% lysine, .65% Ca, and .55% P) was used as the control. Pigs (n = 128; average initial BW of 85.7 kg) were fed the control diet or the control diet without 1) the vitamin premix, 2) the trace mineral premix, or 3) both premixes. Omitting the premixes had no effect on ADG (P>.39); gain/feed (P>.17); carcass backfat thickness (P>.42); and marbling, color, and firmness of the longissimus muscle (P>.11). In Exp. 2, pigs (n = 128; average initial BW of 86.2 kg) were fed the control diet (.65% Ca and .53% P) used in Exp. 1 and the control diet without 1/3 (.56% Ca and .46% P), 2/3 (.51% Ca and .40% P), or all (.47% Ca and .31% P) of the added monocalcium phosphate (MCP). Omitting up to 2/3 of the MCP increased ADG (quadratic effect, P<.02) and had no effect on meat quality (P>.12), but backfat thickness increased slightly (quadratic effect, P<.02). In Exp. 3, pigs (n = 160; average initial BW of 86.6 kg) were fed the control diet used in Exp. 1 or the control without 1) the vitamin and trace mineral premixes, 2) 2/3 of the MCP, or 3) the premixes and 2/3 of the MCP. Treatment had no effects on ADG (P>.23), gain/feed (P>.94), stomach lesions (P>.37), or serum gamma globulins (P>.08). In conclusion, vitamin and trace mineral premixes and up to 2/3 of the supplemental MCP can be omitted during late finishing (i.e., approximately the final 30 d) to reduce nutrient excesses that increase cost of feeding and nutrients excreted in waste material.

“…Similarly, Waldroup et al (1968) reported no incidence of toe and hock dermatitis in broilers fed on a maize-soy diet without TRM premix. Although some previous studies have emphasised the importance of biotin deficiency in FPD incidence (Patrick et al 1943;Jensen & Martinson 1969), our results did not confirm such findings.…”

This study was conducted to assess the effects of omitting vitamin (VIT) and trace mineral (TRM) premixes from the finisher diet on growth performance, antibody production against Newcastle disease (ND) vaccination, leg bone strength and incidence of foot pad dermatitis (FPD) in male and female broiler chickens. Birds were raised on floor pens in a naturally ventilated house using wood shavings as litter. Commencing from day 21, equal number of male and female birds were subjected to one of four VIT and TRM premixes withdrawal treatments as follows: (i) withdrawal from 21 to 42 days, (ii) withdrawal from 28 to 42 days, (iii) withdrawal from 35 to 42 days, and (iv) no withdrawal (control). In comparison to the control group, feed intake, body weights, feed conversion ratios and antibody responses to Newcastle disease vaccination were not affected by any of the supplement withdrawal treatment. Male birds had lower antibody production and higher bone-breaking strength as compared to their female counterparts. Irrespective of gender, withdrawal of VIT and TRM premixes from 21 to 42, and 28 to 42 days adversely affected bone-breaking strength. In conclusion, VIT and TRM premixes can be removed from the diet of male and female broiler chickens from 21 to 42 days without any adverse effects on growth performance, mortality, antibody response and incidence of foot pad dermatitis. However, bone-breaking strength was adversely affected by the withdrawal of VIT and TRM premixes for more than seven days. ARTICLE HISTORY
