“…Likewise, Tayeb and Qader (2012) showed that selenium and vitamin E had no significant effect on carcass weight, carcass parts and dressing percentage at 42 and 49 days of age. As well, our carcass traits findings are consistent with Liu et al (2011), Sarvari et al (2015) and Zakaria et al (2017) who showed that carcass traits were not affected by Zn source or the interaction between Zn source and supplemental Zn level or the high Zn concentration. On contrast, Jahanian et al (2008) reported that increasing Zn supplemental levels from 40 to 80 mg/kg from both inorganic and organic zinc sources increased liver weight percentage.…”

inety unsexed one day old Cobb 500 broiler chicks were used in this experiment. The experiment aimed to study the comparative effect of some feed additives as growth promoters such as selenium and zinc in their inorganic form on broiler growth rate, feed intake, feed efficiency, some blood metabolites and carcass traits by adding them in the drinking water. The chicks were randomly distributed into three equal treatments. Each treatment had 30 chicks divided equally into five replicates. The experimental treatments were: The first treatment was served as a control (T1), while the second (T2) was given 0.8 mg sodium selenite / L of drinking water and the third treatment (T3) was given 1 g zinc oxide/ L. Sodium selenite (T2) showed the heaviest body weight (P<0.01), gained more weight consumed more feed and recorded the best value of feed efficiency ratio (P<0.001) compared to the other treatments. There were non-significant differences between control and zinc treatments in body weight and gain and feed efficiency ratio. There was a significant reduction in feed intake from 21 to 35 days of age and from 1 to 35 days of age for zinc treatment compared to the other treatments and significant increase from 1 to 21 days of age for the same treatment. A significant increase in triiodothyronine (T 3) (P<0.01) was observed in selenium and zinc treatments (T2 and T3 respectively) compared to the control treatment. About plasma urea, creatinine, ALT and AST, total lipid, cholesterol, triglycerides, total protein, albumin, globulin and their ratio (A/G ratio) and carcass traits, there were nonsignificant (P>0.05) differences among the experimental treatments. Zinc treatment (T3) recorded the lowest percent (3.85%) of mortality. It was concluded that supplementation of selenium in broiler drinking water improved broiler performance and zinc addition did not have adverse effects on growth rate and the functions of blood.

“…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.…”

“…There was no effect of Zn levels on the tibial ash content of 42-d-old broilers (p>0.05). Research has shown that supplemental Zn increases blood Zn concentration in laying hens and broiler chickens (Tsai et al, 2016;Zakaria et al, 2017). A linear relationship was observed between 0 and 20 mg/kg supplemental Zn and bone Zn content in broiler chickens from 1 to 21 d of age (Ao et al, 2007;Star et al, 2012).…”

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.

“…This may have been due to the fact that zinc promotes protein biosynthesis (Coleman, 1992). Likewise, Zakaria et al (2017) also supplemented broiler feed with organic zinc (Availa ® Zn Zinpro Corporation, Edina, MN, USA). This study showed that feeding broilers with added organic zinc significantly (P ≤ 0.05) improves the level of protein in the blood.…”

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.
