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.
Prologue Heat stress brings about major physiological changes in poultry birds, which negatively affects feed intake, feed efficiency, production, performance, reproductive efficiency, and disease outbreaks. Reduced feed intake during heat stress decreases vitamins and minerals intake, which leads to decreased serum and liver concentrations of these micro-nutrients. Moreover, mobilization and excretion of minerals and vitamins are increased under stress conditions due to...

Effects of heat stress on plasma calcium concentration, egg production and egg quality Highly productive modern poultry breeds are more prone to heat stress and rising global temperatures is one of the greatest challenge for the industry. It greatly damages a bird’s performance in terms of feed intake, feed conversion, body weight, egg production, rooster activity and hatchability (Nilipour, 1996). Stress of high environmental heat during summer also interfere with the...

The current study was conducted to determine the availability of Lutavit® A 1000 NXT (A-1000), a vitamin (Vit) A acetate product, after a 56-d incubation period. Four Vit A sources (A-1000, B, C, and D) were blended into Vit-trace mineral premix designed to put oxidation stress on the Vit A beadles. These Vit premixes along with a negative control (NC), without Vit A, were stored in two different conditions, Cold Stress (CS) at 4°C or Heat Stress (HS) at 35°C and ≥60% Relative...

APIs MARKET
The APIs market in December generally remains stable and weak, continuing the lingering trend since August. The supply side is widely and deeply affected by the epidemic, with normal production facing increasing challenges and downstream demand continuing to be sluggish, trade channels being cautious in replenishing stocks, and insufficient market confidence.
On December 7, the government...

1. Introduction Nutrition plays a pivotal role in maintaining the health of pullets, quality egg production by laying hens and body growth of broilers (Wang et al. 2017). Nutraceuticals are the nutrients or constituents of animal diet that have nutritional and pharmaceutical importance by preventing various diseases, possessing immunomodulatory potential, providing health benefits and consequently increasing productivity (Dhama et al. 2015; Aronson 2017; Helal et al. 2019;...

The APIs market in November generally remained stable, continuing the lingering trend since August. Supply-side costs are rising, while deals are constrained by downstream demand. Downstream purchases are still subject to the actual need, and there needs more confidence and willingness to stock up and build the position. The supply-demand game has been held this month. It is expected that the recent market trend will continue oscillation and consolidation and need a solid new factor to break...

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...
