“…However, broiler performance was not affected by supplemental Zn levels in the present study. Previous studies had also observed that broiler growth was not affected by dietary Zn concentrations (Bartlett and Smith, 2003; Rossi et al, 2007;Sunder et al, 2008;Owens et al, 2009;Yang et al, 2011;Star et al, 2012;Liao et al, 2013;Pacheco et al, 2017;Zakaria et al, 2017). This is attributed to the Zn content of basal diets (about 30 mg/kg), which is adequate to maintain the growth of broiler chickens from 1 to 42 d of age.…”

The objective of this study was to investigate the optimal zinc (Zn) requirement of broiler chickens based on Zn retention. On the day of hatch, 350 male Ross 308 broilers were randomly assigned to seven treatments with five replicates of ten birds each. Zinc was supplemented as ZnSO 4 •7H 2 O at 0, 20, 40, 60, 80, 100, or 120 mg/ kg in the starter diet (fed from 1 to 21 d of age) and at 0, 16, 32, 48, 64, 80, or 96 mg/kg in the grower diet (fed from 22 to 42 d of age). The analyzed Zn levels were 34.98 and 27.57 mg/kg in the basal starter and grower diets, respectively. Supplemental Zn levels did not influence body weight gain, feed intake, feed conversion ratio, or liver Zn content of broilers at 21 and 42 d of age (p>0.05). Tibia ash Zn content of 21-d-old broilers increased when Zn supplementation level increased from 0 to 40 mg/kg Zn in (p<0.05). The highest breast muscle Zn content in 42-d-old broilers was observed when 100 and 80 mg Zn/ kg was supplemented in the starter and grower diets, respectively. Fecal Zn content, Zn intake, Zn excretion, and Zn retention of 31-to 33-d-old broilers linearly increased with supplemental Zn levels (p<0.05). Zinc retention values, calculated as the difference between Zn intake and Zn excretion, were negative, about zero, and positive when starter/grower diets were supplemented with 0/0 and 20/16, 40/32, and 60/48 and 120/96 mg/kg, respectively. These results indicate that supplementing 40 and 32 mg Zn/kg in starter and grower diets, respectively, promote the growth performance of broiler chickens, while reduce Zn excretion in the environment.

“…It is known that supplementing chicken feed with zinc influences the quality of poultry meat. Yang et al (2011) showed that Zn supplementation in a chicken's diet (in the range from 0 to 200 mg) significantly affects the parameters of meat colour (L* and b*) and water holding capacity. Moreover, Aksu et al (2011) showed that Zn supplementation in chicken feed (as compared to the control group) also affects the parameters of meat colour (L* and a*) and the course of oxidation processes in the meat (it reduces oxidation).…”

Background. Recently, an increase in the consumption of poultry meat has been observed Worldwide. This is related to the growing production of this kind of meat. Intensive poultry meat production affects the level of bird welfare and meat quality. The meat industry is looking for new solutions that can reduce meat quality defects. One of them may undoubtedly be a feed reformulation, of which a supplementation with zinc can be taken into consideration. The aim of this study was to evaluate the impact of Zn supplementation of chicken feed on the technological and sensory quality of meat. Materials and methods. The research was carried out on material taken from 60 carcasses. Half of the group (30 pieces) was fed with Zn in the form of nonorganic compounds (zinc oxide) and the other 30 chickens were fed zinc in its organic form, and amino acids (ratio 1:1). After the broilers were slaughtered, the meat quality was evaluated in the breast muscle, and was based on pH value, color parameters, natural drip loss, cooking loss, microbiological status, sensory quality, instrumental shear force and lipid oxidation status. Results. The obtained results show that lower levels (p ≤ 0.01) of drip loss (1.04%), and higher amounts (p ≤ 0.01) of glucose (4.61 mmol/l) and protein (0.7%) were found in the meat from the group fed with zinc in organic form as an additive. Moreover, the meat from this group was less red (a* value =-0.46 vs. 0.11) and less yellow (b* value 8.41 vs. 10.16) at the same time (p ≤ 0.01). There were no significant differences between the examined groups for cooking loss, microbiological status, lipid oxidation and sensory quality. Conclusion. It should be stated that Zn supplementation in a form with amino acids has a beneficial effect on the quality of poultry meat as far as drip loss reduction is concerned.

“…In recent years, modifications of broiler feed consumption (FC) to support metabolic and immunologic system function (Yang et al 2011, Conly et al 2012 or skeletal development and welfare have been researched (Su et al 1999, Duncan 2001, European Commission 2010. The especial importance of supplementing feed with manganese (Mn) has been emphasized in this connection (Henry et al 1989, Conly et al 2012.…”
