Vitamins in poultry nutrition
Vitamins are a group of organic compounds that poultry require in small quantities. Despite the low requirement levels, vitamins are essential for normal body functions, growth, and reproduction. A deficiency of one or more vitamins can lead to a number of diseases or syndromes. Vitamins are divided into two categories: fat-soluble and water-soluble. The fat-soluble vitamins are A, D, E, and K. Vitamin A is required for normal growth and development of epithelial tissue (skin and the linings of the digestive, reproductive, and respiratory tracts) and reproduction. Vitamin D3 is required for normal growth, bone development, and eggshell formation. Vitamin K is essential for blood clot formation. The water-soluble vitamins include vitamin C and the B vitamins. The B vitamins include vitamin B12, biotin, folacin, niacin, pantothenic acid, pyridoxine, riboflavin, and thiamin. The B vitamins are involved in many metabolic functions, including energy metabolism. Poultry can make vitamin C, so there is no dietary requirement established for this vitamin. Vitamin C supplementation is useful when birds are in stress.

Introduction: Vitamins are defined as a group of complex organic substances that are essential for normal metabolism and their deficiency in the diet causes disorders among animal species. These essential nutrients can not be synthesized either at all or to some extent by the animal body. Therefore, it is important to ensure the availability of these micronutrients through diet according to the requirements to get optimum productivity, performance and overall health...

APIs MARKET
In October, the price fluctuation of most APIs was slight, mainly because of the lack of downstream demand after the National Day holiday. There was a lack of effective stimulus in the APIs market, and there were no apparent factors on both the supply or demand sides to push the price up. Due to increased sales pressure on the supply side, some suppliers have new price releases or provide preferential delivery conditions. The downstream procurement is...

Vitamin D, also known as calciferol, is the inactive form of vitamin D that can be ingested through diet or be generated endogenously in the skin when exposed to UV light. Vitamin D is converted into its active form 1, 25-dihydroxycholecalciferol (1,25-(OH)2 D3), following a two-step hydroxylation process mediated by two key...

Although the first mentions to “choline” date from XIX century (In 1850, Theodore Gobley already described a substance “lecithin”, and then, in 1862, Adolph Strecker heated lecithin from bile, which generated a new nitrogenous chemical termed “choline”), choline’s role nutrition was not well known until 1930s. Since then, several researches have established it as an essential nutrient, which main functions could be summarized...

I. INTRODUCTION Early life stress may have a negative impact on the performance of broiler flocks. It has been observed that a severe cold stress (12°C below the normal temperature) throughout the life cycle of broilers negatively impacts production parameters (Su et al., 2020) and immune system development (Zhao et al., 2013). The use of vitamins and other molecules with antioxidant properties have been investigated in poultry undergoing different challenge models...

There has been much research recently to refine broiler requirements for calcium (Ca) and phosphorus (P), especially since the routine inclusion of phytase in broiler diets (Li et al., 2016). Phosphorus and Ca play significant roles in bone metabolism and vitamin D is also pivotal to maintaining bone integrity through the modulation of Ca metabolism (Li et al., 2017). The broiler requirement for vitamin D according to NRC 1994 is 200 IU/kg while, commercially, dietary concentrations as high...

1. Introduction Coccidiosis is a worldwide disease caused by the Apicomplexa protozoa of Genus Eimeria [1]. This parasitic disease causes economic losses in poultry industry due to malabsorption, reduced weight gain (explained by a reduced feed intake and as well as nutrient absorption), increased mortality and the use of anticoccidial drugs and vaccines [2, 3] and remains as a major issue for poultry producers in a large number of countries including USA [4], costing for the...

One of the greatest challenges to production facing poultry farmers in India is heat stress and the strain that it causes to the bird. Climatic conditions in India are such there is intense radiant energy for an extended period of time. Poultry create a large quantity of metabolic heat and accumulate additional heat from radiant energy. Heat production and accumulation, coupled with compromised cooling capability because of environmental conditions, causes heat load in the bird to increase...

The eggshell consists of 95% calcium carbonate, the necessary calcium is obtained from the feed or the bones of the layer. Calcium is absorbed in the intestine and its absorption and metabolism are regulated by vitamin D. To avoid related problems, regular supplementation with calcium and vitamin D3 is recommended. PlusVet Animal Health developed PhytoMax © which is a combination of vitamins, calcium in chelate form, microminerals and essential oils to add to the drinking water of layers and...
