1. Organic minerals with different chemical characteristics in diets for Hy-Line White laying hens: performance, biometry of digestive organs, and bone quality
ABSTRACT Two trials were carried out to evaluate the effect of groups of organic minerals with different chemical characteristics on the performance, egg quality, biometry of digestive organs, and bone quality of laying hens in the first and second laying cycles. In the first cycle, 180 layers at 72 weeks were used in a completely randomized design (CRD) wit

2. Enzymes inhibitory and radical scavenging potentials of two selected tropical vegetable (Moringa oleifera and Telfairia occidentalis) leaves relevant to type 2 diabetes mellitus
ABSTRACT Moringa oleifera Lam., Moringaceae, and Telfairia occidentalis Hook. f., Curcubitaceae, leaves are two tropical vegetables of medicinal properties. In this study, the inhibitory activities and the radical scavenging potentials of these vegetables on relevant enzymes of type 2-diabetes (α-amylase and α-glucosidase) were evaluated in vitro. HPLC-DAD

3. Chelated Minerals and Limestone Particle Sizes on Performance and Bone Quality of Brown-Egg Layers
ABSTRACT This study aimed to evaluate productive performance, egg quality, and bone quality of commercial brown-egg layers fed diets containing organic and inorganic minerals and three limestone particle sizes. A total of 288 birds at 64 weeks of age were distributed in a completely randomized design in a 2 × 3 factorial arrangement (two mineral sources and

4. The effect of supplementing sow and piglet diets with different forms of iron
ABSTRACT The objective of this study was to evaluate the effect of chelated iron supplementation on gestating and lactating sows and on their suckling and weaned piglets. Reproductive traits, piglet performance, hematological parameters, and the iron concentrations in colostrum, milk, and stillborn livers were measured. Ninety-six sows were subjected to one

5. Effects of Supplementation of Ionized or Chelated Water-Soluble Mineral Mixture on the Live Performance, Nutrient Digestibility, Blood Profile, Egg Quality, and Excreta Microbiota of Laying Hens
ABSTRACT In total, 216 Hy-Line brown laying hens (40-week-old), were used in a 5-week experiment to evaluate the effects of ionized or chelated water-soluble mineral mixture supplementation on live performance, nutrient digestibility, blood characteristics, egg quality, and excreta microbiota. Layers were randomly assigned to one of three dietary treatments

6. Screening of iron-enriched fungus from natural environment and evaluation of organically bound iron bioavailability in rats
Iron is an essential element for nearly all living organisms, and its deficiency is the most common form of malnutrition in the world. The organic forms of trace elements are considered more bioavailable than the inorganic forms. Although Saccharomyces cerevisiae can enrich metal elements and convert inorganic iron to organic species, its tolerability and tr

7. Development and characterization of the amidoxime/Europium (ІІІ)-chelated complex fibers
This paper presents a study of the amidoxime/Europium (ІІІ)-chelated complex (AECC) fibers which can be used as functional fibers for technical textiles such as decorations, protections and medical textiles etc. First, the EuCl3solution were prepared and reacted with amidoxime fibers using optimized process conditions at 50 °C, 5 hours. Subsequently, the

8. Effect of supplementing finishing pigs with different sources of chromium on performance and meat quality
The objective was to evaluate the dietary supplementation of different sources of chromium (inorganic: chromium sulfate and chelated: chromium-methionine) during the finishing period of pigs to obtain improvements in the animal performance, and carcass and meat quality. The statistical design was randomized blocks, where 44 barrows, with an initial weight 60

9. Avaliação de fontes, absorção foliar e translocação de zinco (68Zn) em laranjeiras / Sources evaluation, foliar uptake and zinc translocation (68Zn) in Orange
Studies of zinc fertilization on citrus foliar developed in Brazil are mostly limited to information of the nutrients quantities absorbed by the leaves, but the zinc transport of the leaves to other parts of the plants need to be clarified. Most investigations on this subject is vast array of conflicting results. As a result, the use of stable isotope techni

10. Efeito de fontes dietéticas de ferro sobre o desempenho de reprodutoras pesadas e conteúdo de ferro no ovo / Dietary effects of iron sources on broiler breeders performance and egg iron contents
O objetivo deste estudo foi comparar dietas com ou sem adição de farinha de carne e ossos e diferentes fontes de suplementação de ferro (Fe) em dietas para matrizes de corte. Sessenta matrizes de corte Cobb, 22 semanas de idade, foram alojadas individualmente em gaiolas e alimentadas com uma dieta (15,6% PB, 2.840 kcal EM /kg, 3,2% Ca, 0,45% de fósforo

11. Effect of dietary organic selenium and zinc on the internal egg quality of quail eggs for different periods and under different temperatures
The objective of this study was to evaluate the internal quality of eggs of Japanese quails fed diets supplemented with chelated selenium and zinc. The experiment was carried out for 120 days, and 144 birds were divided in random blocks into four treatments (control; 0.3 ppm Se; 60 ppm Zn and 0.3 ppm Se + 60 ppm Zn). Ten, 14, 18, and 22 weeks after the begin

12. Chelated minerals for poultry
Organic minerals have been subject of an increasing number of investigations recently. These compounds can be considered the most significant event regarding commercial forms of minerals targeting animal supplementation in the last decades. Minerals, especially metals, are usually supplemented in poultry feeds using cheap saline sources and have never requir
