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.
The current market for vet APIs is quiet, with the price of doxycycline hydrochloride, which was in the spotlight and leading the way, falling from its high level this month. There is a lack of popular products in this period, but it is just the stable price trend of regular products that are keeping the whole market stable.
With the arrival of the peak breeding season and the gradual end of high-temperature maintenance, the domestic market entered the so-called "Golden Nine and...

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...

The importance of vitamin nutrition in poultry feeding has been recognized for decades, yet precise vitamin requirements for modern, high producing have not been investigated. Because of their low inclusion rates, vitamins have a relatively small impact on the cost of feed. Many vitamins lose activity over time or under high-temperature feed processing. Vitamins, especially the water-soluble vitamins, are tolerated at many times the established minimum recommended levels. Finally, the...

Bird performs well within a certain range of environmental temperatures. As the temperature gets higher than the range, the bird falls on stress generally called heat stress. Heat stress is the most significant stressors influencing poultry productivity and causing considerable economic losses in the poultry industry. This induces several negative effects on physiological response of bird. Reducing feed consumption, body weight gain, feed efficiency, egg production and immune response are of...

APIs MARKET At present, China APIs market remains weak, with the majority of wait-and-see. In terms of supply, although the production load of the factory is declining and the production cost is relatively high, the overall market supply is sufficient. In terms of demand, the market for mid-and downstream breeding enterprises is sluggish after the Chinese New Year holiday. On the whole, most mid-and upstream manufacturers have a certain degree of inventory pressure, and...

Introduction: Due to the constant genetic evolution in both the production of broilers, nutritionists must constantly adapt their nutritional recommendations and feeding programs to maximize economic results at all times. These management and nutrition decisions must take into account: the animal (potential for growth), environmental conditions and the composition of the feed, which affect feed consumption and, consequently, the performance of birds. And economic...

INTRODUCTION The rapid growth of modern broilers in a relatively short period of time requires a parallel increase in the size or capacity of supply organs, such as those of the cardiovascular and respiratory systems. However, due to the slower development of these organs relative to body growth rate, the capacity to balance body energy is compromised, particularly under extreme environment conditions, such as cold stress (Shahir et al., 2012; Shinder, 2002). Cold...
