“…These findings (Experiment 1) were similar to those reported by Skinner et al (1992) and Khajali et al (2006) as they showed that withdrawal of vitamin and mineral premix from the finisher diet of broilers did not affect body weight gain. Skinner et al (1992) suggested that the lack of a withdrawal effect could be related to the availability in the body of vitamins and minerals for further growth, as the amount of these supplements usually exceeds two or three times the recommended requirement in poultry diets. Differences in productive performance may be due to the rearing system (floor litter or cages) and/or diet composition.…”

“…They also cause a specific deficiency disease if absent from the diet and cannot be synthesized by the host animal to meet vitamin requirements (Coelho and McNaughton, 1995). Skinner et al (1992) reported that removing vitamin (V) and trace mineral (TM) premixes from broiler diets from 28 to 49 days of age had little impact on growth performance. In contrast, Deyhim and Teeter (1993) detected reduced performance for several growth and carcass traits when the same withdrawal period was examined.…”

Two experiments were conducted the to compare the effect of a decreasing amount of vitamin premix in diets inbroilers from 29 to 42 days of age on carcass composition and blood chemistry in floor (Experiment 1) and battery cage (Experiment 2) systems. At 35 and 42 days of ages, one bird of each replicate was slaughtered and carcass composition was measured. Blood concentrations of alkaline phosphatase (ALP) and calcium (Ca) were used to diagnose vitamin D3 deficiency and enzymes aspartate amino transferase (AST) to identify vitamin E deficiency. Floor raised birds showed that vitamin premix reduction/withdrawal at 29 days of age did not impair body weight (BW), carcass composition, ALP and Ca during the final rearing period. However, diet without vitamin premix (T1) had a higher AST at 42 days of age than the other diets. Birds reared in cages were slightly more sensitive to vitamin premix reduction/withdrawal, probably due to the impracticality of performing coprophagy. Diet without vitamin premix (T1) had a lower BW, carcass breast and thigh yield at 42 days of age; also serum ALP, AST and Ca were impaired. In conclusion, the withdrawal of vitamins is not a reasonable option but it is possible to reduce vitamin premix in finisher broilers' diets without negative effects on performance and on some metabolic traits during the finisher period with both methods of rearing.

“…The practice of omitting both VIT and TRM premixes from the diet of broilers may substantially reduce production costs. Skinner et al (1992), and Christmas et al (1995) reported that the withdrawal of both premixes from 28 to 49, and 35 to 42 days of age had negligible effect on growth performance. It has also been reported that, humoral immunity is not affected by withdrawal of both VIT and TRM premixes during the finisher period (Deyhim & Teeter 1993;Khajali et al 2006).…”

“…There is a paucity of information and literature regarding the effects of withdrawal of dietary VIT and TRM premixes in different genders. A single available report by Skinner et al (1992) stated that there was no gender Â withdrawal interaction for growth performance. However, the existence of interactions for other parameters such as bone characteristic remains unclear.…”

“…However, the existence of interactions for other parameters such as bone characteristic remains unclear. Moreover, the study conducted by Skinner et al (1992) was carried out under temperate conditions and it remains to be seen what the scenario would be under tropical conditions. It has been shown that there is an association between growth rate and sensitivity to heat stress in broiler chickens (Cahaner et al 1996).…”

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
