“…However, studies show that both the recommended doses and estimated requirements of the hens are too high, and that the availability of inorganic compounds is insufficient (Esenbuga et al, 2008;Zhao et al, 2010). This is due to the limited absorption capacity of the gastrointestinal tract caused by the attachment of these micronutrients by various compounds (phytates, fiber fractions, and tannins).…”

Abstract. The aim of study was to evaluate the quality of hen eggs influenced by supplementation of copper with lysine chelate (CHL). The material consisted of eggs from two groups of Hy-Line Brown laying hens aged 300 days. Group I, negative control (NC), did not receive any additives. The hens from group II were treated with CHL at a dose of 30 mg Cu L −1 with drinking water. After 4 weeks of supplementation, 60 eggs from each group were randomly collected for quality analysis. The characteristics of the whole egg and its individual elements (shell, yolk, and albumen) were evaluated. The supplementation of CHL increased the egg weight, as well as the weight and height of albumen. There were no changes in the shell strength parameters, and its darker color may increase potential consumer acceptance, but requires confirmation by sensory analysis of the eggs. The copper addition was relatively small, but even this dose caused some changes in egg quality. Little changes in the mineral composition of individual elements of the eggs have been reported. It is therefore very important to continue research to find the smallest effective dose of this micronutrient, to study the duration of time it should be given in order to obtain the best quality of eggs, and to minimize the mineral disorders in organisms.

“…Os minerais orgânicos apresentam maior biodisponibilidade nutricional (ZHAO et al, 2010;RICHARDS, 2010), consequentemente, melhor absorção e distribuição no organismo das aves, maximizando o desempenho zootécni-co, a qualidade da carcaça, e a imunidade (BORGES, 2010), possibilitando uma menor inclusão nas formulações nutricionais (GHEISARI, 2010) e consequentemente uma menor excreção nas fezes (BORGES, 2010).…”

Cobre e seu efeito na dieta de frangos de corte (Gallus gallus) -revisão de literatura. Arq. Ciênc. Vet. Zool. UNIPAR, Umuarama, v. 20, n. 1, p. 35-40, jan./mar. 2017. RESUMO:O cobre é um mineral essencial ao metabolismo e seu uso tem sido associado à melhora do desempenho zootécnico, aumento da resistência ao estresse e doença nas aves. A indústria avícola com o intuito de maximizar o desempenho produtivo formula normalmente as dietas com altas doses da fonte inorgânica de cobre, o que contribui para o desequilíbrio metabólico e como consequência aumenta a poluição ao meio ambiente. Dessa forma, o uso de fontes orgânicas de cobre tem sido estimulado. Sendo assim, o objetivo do presente trabalho foi revisar a utilização do cobre na dieta de frangos de corte com enfoque para os benefícios das fontes orgânicas. Conclui-se que fontes mais biodisponíveis de cobre são uma oportunidade para diminuir sua inclusão, mantendo o desempenho do animal, por meio da redução de agentes patogênicos, melhora na digestibilidade e redução ao impacto ambiental em dietas de frango de corte. PALAVRAS-CHAVE: Aves. Biodisponibilidade. Desempenho zootécnico. Impacto ambiental. THE USE OF COPPER ON BROILER (Gallus gallus) DIETS -A LITERATURE REVIEW ABSTRACT:Copper is an essential mineral for the metabolism and its use has been associated with improved zootechnical performance and increased resistance to stress and diseases in broilers. In order to maximize the productive performance, poultry nutritionists usually formulate diets with high doses of copper inorganic sources, contributing thereby to favor metabolic imbalance and environmental pollution. The purpose of this study was to review the use of copper in broiler diets with a focus on the benefits of organic sources. It can be concluded that more bioavailable sources of copper represent an opportunity to reduce its inclusion without compromising animal performance. Moreover, proper management of copper in broiler diets can contribute to reduce pathogens, improve digestibility and reduce the environmental impact of the poultry industry.

“…Previously conducted several studies have demonstrated that the development of tibial dyschondroplasia could be minimized by means of various modifications to the rations fed to animals (15,18,19,34). Oso et al (23) reported that different calcium sources incorporated into broiler rations have different effects on bone mineralisation and the development of TD.…”

Summary:Tibial dyschondroplasia (TD) deteriorates the welfare of broiler chickens and causes economic loss. The present study was aimed at the investigation of the effect of TD on metabolic parameters and the demonstration of the aetiology of this disorder. For this purpose, blood serum mineral, lipid, protein, glucose, uric acid and enzyme levels, and histopathological alterations in the tissues of the tibiotarsal joint were determined. Ten broiler chickens suffering from TD and 10 healthy broiler chickens, all which were of the Ross 308 breed, constituted the material of the study. Analyses showed that calcium, phosphorus and free fatty acid blood serum levels were lower, whilst triglyceride, cholesterol, low density lipoproteins (LDL), very low density lipoproteins (VLDL) rates and uric acid and creatinine levels were higher in animals suffering from tibial dyschondroplasia, compared to healthy animals (P<0.05). No statistically significant difference existed between the glucose and amylase levels and alanine aminotransferase (ALT), aspartate aminotransferase (AST), γ-glutamyltransferase (GGT), and alkaline phosphatase (ALP), activities of broilers diagnosed with tibial dyschondroplasia and healthy broilers. The histopathological examination of the tissues of the tibiotarsal joint of the animals diagnosed with TD revealed degenerative alterations characterized by the dominance of hypertrophy and the lack of urate crystals and calcification in chondrocytes. In animals with TD, calcium and phosphorus blood serum levels were low, whilst the lipid profile and amount of uric acid were high. On the other hand, ALP enzyme activity was determined not to display any alteration.Key words: Broiler, metabolic parameter, tibial dyschondroplasia. Etçi piliçlerde tibial diskondoplazinin metabolik parametrelere etkisiÖzet: Tibial diskondoplazi (TD) piliçlerin refahını bozmakta ve ekonomik kayıplara neden olmaktadır. Bu çalışma TD'nin metabolik parametrelere etkisini ve etiyolojisini belirlemek amacıyla yapılmıştır. Bu nedenle hayvanların kan serumlarında mineral, lipit, protein, glikoz, ürik asit ve enzim değerleri ve tibiotarsal eklem dokusundaki histopatolojik değişimler tespit edilmiştir. Araştırmada10 adet TD'li ve 10 adet sağlıklı broiler (Ross 308) kullanılmıştır. Tibial diskondoplazili hayvanların kan serumlarındaki kalsiyum, fosfor seviyesi ve serbest yağ asitleri oranı sağlıklı hayvanlardan düşük; tigliserit, kolesterol, düşük yoğunluklu lipoprotein (LDL), çok düşük yoğunluklu lipoprotein (VLDL) oranları, ürik asit ve kreatinin miktarları ise yüksek bulunmuştur (P<0.05). Tibial diskondoplazili ve sağlıklı broilerin glikoz ve amilaz seviyeleri ile alanin aminotransferaz (ALT), aspartat aminotransferaz (AST), γ-glutamyltransferaz (GGT), ve alkalin fosfataz (ALP), aktiviteleri arasında ise istatistiksel farklılık tespit edilmemiştir. Araştırmada TD'li hayvanların tibiotarsal eklem dokusunun histopatolojik incelenmesinde dejeneratif değişiklikler, kondrositlerde hipertrofinin baskın olduğu, ürat kristalleri ve kalsifika...
