Performance of broiler breeders supplemented with organic and inorganic minerals

Abstract

The present study aimed to evaluate the use of organic and inorganic minerals in Cobb500 broiler breeder diet and its effects on the performance. The birds were housed in an experimental house at Poultry Laboratory of the Federal University of Santa Maria with 20 fl oor pens of 4.61m2 each. The experiment was conducted between 51st and 65 th weeks of age of birds. The design was completely randomized with four treatments and fi ve pen replicates with 22 hens and 2 roosters each. The treatments evaluated were: PI=100% mineral inorganic premix; PO= 100% mineral organic premix: PI+PO= 70% mineral inorganic premix + 30% mineral organic premix and PI+Zn= 100% mineral inorganic premix, except zinc mineral, that was 70% inorganic form and 30% organic form. The following parameters of performance and egg quality were evaluated: laying rate, body weight, egg, albumen and yolk weight, yolk color and specifi c gravity of eggs. These parameters were performed one day per week throughout the experimental period to evaluated egg quality. Under the conditions and time that the experiment was conducted, the use of organic minerals had no signifi cant effect on the performance and egg quality parameters evaluated in the broiler breeders.

Comparative efficacy of hydroxychloride and organic sources of zinc, copper, and manganese on egg production and concentration of trace minerals in eggs, plasma, and excreta in female broiler breeders from 42 to 63 weeks of age

“…The results indicated no difference in the production performance in terms of HDEP and egg mass production, aligning with the findings of Xiao et al (2015) and Jiang et al (2021) . As expected, HDEP decreased as the hen aged; the observed decline of nearly 10% in HDEP over the 10-wk period in our study aligns with the egg production trends observed in a study by Pedro et al (2021) . In that study, there were no differences in HDEP based on TM source in BB fed InO or OR sources of TM but they noted an age dependent decrease in HDEP from 62.1% at 55 WOA to 52.2% at 65 WOA, for InO and OR sources, respectively.…”

Nano-Sized Selenium Maintains Performance and Improves Health Status and Antioxidant Potential While Not Compromising Ultrastructure of Breast Muscle and Liver in Chickens

“…It has been shown that the inorganic form of Se has low bioavailability, accelerates oxidation processes and can be toxic, especially at high concentrations. In contrast, organic-Se and nano-Se exhibit low toxicity, high adsorption capacity, high bioavailability and high catalytic efficiency in chickens, sheep and goats [ 46 , 47 , 48 ]. Selenium is an important trace element that upregulates a vital component of the antioxidant defiance mechanism by controlling the body’s glutathione pool and Se-dependent antioxidant enzymes such as superoxide dismutase and glutathione peroxidase [ 49 , 50 ].…”
