“…Contrary to the present study, organic Mn, Zn and Cu resulted in an increase in egg weight when compared to their inorganic form at 72 to 80 weeks of age (20). In another study, an increase in the egg laying rate was observed in hens of 96 to 103 weeks of age that received organic Cu or Cu+Mn+Zn, and an enhancement in egg weight was observed when the hens received organic Zn (27).…”

“…Egg quality characteristics, except for eggshell breaking strength, were not significantly affected by the different forms and levels of Mn, Zn, Cu and Cr (P > 0.05) in the present study. In accordance with the findings of the present study, the supplementation of organic Zn, Mn and Cu to the diet did not affect the eggshell rate and thickness (20). In addition, egg shape index and eggshell thickness (8,34) or haugh unit (8,24) were not influenced by supplemental dietary organic Cr levels (0.10 to 0.80 mg/kg).…”

“…Gheisari et al (11) showed that a corn-soybean diet supplemented with the organic forms of Zn, Mn and Cu at a dosage 50 % to 75 % lower than available levels is sufficient to maintain performance and egg quality characteristics in laying hens. On the other hand, Maciel et al (20) recorded that when compared with inorganic form, organic trace minerals (Zn+Mn+Cu) decreased the damaged egg rate. : means within columns with no common superscripts are significantly different (P<0.05).…”

Summary:This study was conducted to compare the effects of organic or inorganic Mn, Zn, Cu and Cr mixture using two different levels (80, 60, 5 and 0.15 mg/kg and 40, 30, 2.5 and 0.07 mg/kg, respectively) on the performance, egg quality and hatching characteristics of laying breeder hens. The experiment began with a total of 360 hens from Barred Rock line at 50 weeks of age and continued for 16 weeks. Each of the four dietary treatments was randomly assigned to six replicates, which included 15 hens each. Different trace mineral applications did not result in a significant effect on performance parameters such as livability, body weight gain, egg production, egg weight and mass, feed intake, and feed conversion. No significant differences in egg quality parameters such as damaged egg rate, shape index, eggshell rate and thickness, albumen height and haugh unit were observed among the groups. However, the low level of trace minerals resulted in a significant reduction in eggshell breaking strength (P < 0.05). Different trace mineral applications did not show a significant effect on hatching and fertilised eggs ratio. The dietary supplementation of organic (chelated with methionine) Mn, Zn, Cu and Cr at high levels (80, 60, 5 and 0.15 mg/kg, respectively) increased the hatchability of the fertilised eggs and hatchability compared to that of the other groups (P < 0.05).Key words: Breeder hen, egg quality, hatching characteristics, performance, trace mineral. Damızlık yumurta tavuğu yemine organik veya inorganik mangan, çinko, bakır ve krom ilavesinin performans, yumurta kalitesi ve kuluçka özellikleri üzerine etkileriÖzet: Bu araştırma, iki farklı seviyede organik veya inorganik Mn, Zn, Cu ve Cr karışımının (sırasıyla, 80, 60, 5 ve 0.15 mg/kg ve 40, 30, 2.5 ve 0.07 mg/kg) damızlık yumurta tavuklarının performans, yumurta kalitesi ve kuluçka özelliklerine etkilerini karşılaştırmak amacıyla düzenlenmiştir. Araştırma, 50 haftalık yaşta, toplam 360 adet Barred Rock hattı ile başlatılmış ve 16 hafta sürdürülmüştür. 4 ana grup her biri 15 tavuk içeren 6 tekerrüre rastgele dağıtılmıştır. Farklı iz mineral uygulamaları yaşama gücü, canlı ağırlık kazancı, yumurta verimi, yumurta ağırlığı ve kütlesi, yem tüketimi ve yemden yararlanma gibi performans parametreleri üzerinde önemli bir etki göstermemiştir. Yumurta kalite parametrelerinden, hasarlı yumurta oranı, şekil indeksi, kabuk oranı ve kalınlığı, ak yüksekliği ve haugh birimi bakımından gruplar arasında önemli farklılıklar bulunmamıştır. Bununla birlikte, düşük iz mineral seviyesi kabuk kırılma mukavemetinde önemli bir azalmaya sebep olmuştur. (P < 0.05). Farklı iz mineral uygulamaları, kuluçkalık ve döllü yumurta oranları üzerine önemli bir etki göstermemiştir. Organik (metiyonin şelatı) Mn, Zn, Cu ve Cr' un yüksek (sırasıyla, 80, 60, 5 ve 0.15 mg/kg) düzeyleri çıkış gücü ve kuluçka randımanını diğer gruplara göre artırmıştır (P < 0.05). Anahtar sözcükler: Damızlık tavuk, iz mineral, kuluçka özellikleri, performans, yumurta kalitesi.

-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.
