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 Year after year laying hens are becoming more productive, largely due to great success in genetic improvements. However, this improvement in productivity has made the animals increasingly demanding in nutrition, health and management. From the nutritional point of view, one important requirement is undoubtedly that related to increased egg production and improvement in eggshell quality. The above means an increase in the contribution requirements and the balance of...

Vitamin B6
Guangji Pharmaceutical Holding Co., Ltd. announced on August 16 the resumption of production of vitamin B6.
On September 18, 2017, Guangji Pharmaceutical’s subsidiary Hubei Huisheng Pharmaceutical Co., Ltd. (Huisheng Pharma) shut down production due to fire in the workshop. The resumption works were started on March 22, 2018, and completed at the end of June. The relevant production process has been optimized and...

Introduction The use of in ovo technology is a very innovative field in the research and industry application, including novel means of vaccination and embryonic nutrient supplementation. As defined by the early work developed by Uni and Ferket (2003), in ovo feeding is the administration of exogenous nutrients and other agents into the amnion of the late-term avian embryo, and it can advance the development of the growing embryo before and after hatch. Similarly, in ovo feeding...

Introduction Vitamin D is a naturally synthesized lipid soluble vitamin and has a broad range of physiological properties, including profound effects upon immune system [1–3]. Ultraviolet B (UV-B) irradiation of epidermal cells constitutes the primary step for photolytic conversion of 7-dehydrocholesterol to Vitamin D. Modern poultry farming practices have led to an increase in density housing with minimal ultraviolet light B (UV-B) exposure. Thus, eggs produced from...

INTRODUCTION Nowadays, there are a lot of concerns to finding non-synthetic alternatives for antibiotics among the researchers. The positive effects of herbal plants on broilers have been reported by many studies. Herbs showed anti biotical potential, hypocholestrolemic effects and growth promoting, which have drawn the researcher’s attention themselves [1]. Organic poultry...

Introduction A delicate balance between antioxidants and prooxidants in cells is an important determinant of various physiological processes and maintenance of this balance is the main aim of so called an integrated antioxidant system built in the animal body. This system was developed during evolution to provide an antioxidant defence and give a chance for animals to survive in oxygenated atmosphere. Recent data suggest...

INTRODUCTION The levels of vitamins for poultry have changed a little over the last 40 years; however, the modern broiler has improved drastically its performance during the same period. Furthermore, an optimum level of vitamins is crucial under high stress condition to allow the birds achieve good performance and adequate health status. In this context, aflatoxin contamination of foods and livestock feeds became a great...

Hubbard breeder hens are capable of peak egg production around 86% under commercial conditions, with sustained peaks over 80% for 12 weeks. This high egg output is only possible with superior management and nutrition, part of which is a well-fortified high energy diet. These high persistent peaks also mean that we have to supply adequate vitamins in the feed, not only for the hens very active stage of reproduction, but also to ensure optimum hatchability and chick quality. Unfortunately, what...

WATER Water is probably the most important nutrient for poultry because a lack of adequate supply will adversely affect the bird's performance more quickly than a shortage of any other nutrient. This is why it is so important to keep an adequate supply of clean, fresh, cool water before the birds at all times. An automatic waterer, placed in the coolest area of the house or pen is probably best for most small-flock operations. If manually...

Achieving maximum health and performance of poultry requires nutritionally balanced diets. One of the common issues with regard to back yard flocks relates to poor or inadequate feeding programs that can lead to vitamin and mineral deficiencies for the birds. Vitamins and minerals are very important components of a chickens diet and unless a formulated ration is feed, it is likely that deficiencies will occur. Poultry require all known vitamins except C. Some vitamins are soluble in...
