Different trace mineral sources and recommendations in the performance and quality of eggs from Dekalb White layers

Abstract

-This work aimed to evaluate the performance and egg quality of lightweight laying hens supplemented with a high biological value mineral, carbo-amino-phospho-chelates (CAPC), compared with inorganic minerals (sulfates), at different recommended values. A total of 320 Dekalb White hens, between 53 and 77 weeks of age, were distributed in a completely randomized design into two treatments, 10 replicates of 16 birds each. The treatments consisted of a reference diet formulated according to breed manual recommendations, in which one group was supplemented with a trace mineral source, CAPC (Cu, 8.6; Fe, 43.7; Mn, 56.4; Se, 0.34; and Zn, 43.7 mg/kg) and the other with a sulfate source, using the levels recommended in the breed manual (Cu, 8; Fe, 60; Mn, 70; Se, 0.25; and Zn, 60 mg/kg). There was no effect of trace mineral supplementation on egg production variables, feed conversion ratio by mass or by dozen eggs, and eggs per housed bird. However, there was an increase in feed intake and weight and mass of eggs when birds fed diet supplemented with CAPC. Regarding egg quality, CAPC supplementation increased the albumen weight and percentage, shell weight, thickness, and strength, and Haugh unit. The eggs from birds fed CAPC supplementation showed higher levels of iron and zinc when compared with eggs from birds fed the sulfate source diet. Better quality rates were observed in variables related to shelf life for the group that received CAPC. Trace mineral sources and recommendations in the diets of high genetic potential laying hens need to be reassessed and allow us to conclude that totally replacing the sulfate for different recommendations of CAPC in laying hen diets helps to improve quality characteristics as well as the nutritional value of eggs.

Natural Products of Plants and Animal Origin Improve Albumen Quality of Chicken Eggs

“…In same line, organic minerals such as dietary carbo-aminophospho-chelates in comparison to the sulphate form (inorganic) enhanced HU values (90.2 vs. 84.95) and other albumen indices in laying hens (164). Calcium in laying pigeons promoted albumen transparency (165).…”

Potential Implications of Natural Antioxidants of Plant Origin on Oxidative Stability of Chicken Albumen during Storage: A Review

“…The other albumen indices were also affected by storage. Extended storage time decreased albumen weight [14,57] and albumen percentage [58]. This decrease in albumen weight was due to a decrease in the thick albumen weight and an increase in yolk weight, suggesting that water diffused from the albumen through the vitelline membrane into the yolk during storage.…”

“…Natural antioxidants in the form of organic trace elements chelated with amino acids and probiotics extend the shelf life of albumen during storage. For example, carbon chelates (CAPC) [58] improved the HU value of eggs stored at 25 • C for 21 d compared to controls, 100 mg/kg zinc-methionine [104] and selenium probiotics [105] improved the HU value in eggs stored for 15 days and 6 days, respectively. In another study, selenized glucose at 10 mg/kg enhanced HU values by 17% compared to controls [54].…”

Effect of In Ovo Injection of Organic Zinc, Manganese and Copper on Hatchability Parameters and Some Tissues‘ Properties in Quail Breeder

“…These nutrients are important skeletal development of embryo (Favero et al, 2013;Torres and Korver, 2018), maintaining bone health and development of bone (Leach, 1988;Rucker 1988;Olgun and Aygun, 2016). Organic trace element sources which have higher bioavailability and no performance adverse effects have been used with smaller quantities than inorganic mineral sources (sulphate and oxide) in the poultry diets (Pereira et al, 2018).…”
