Poultry nutrition - Other additives
Alternative feed additives have promising importance in broiler production due to the ban on the use of certain antibiotics. The most used antibiotic alternatives in broiler production are phytogenics, organic acids, prebiotics, probiotics, enzymes, and their derivatives. Antibiotic alternatives have been reported to increase feed intake, stimulate digestion, improve feed efficiency, increase growth performance, and reduce the incidence of diseases by modulating the intestinal microbiota and immune system, inhibiting pathogens, and improving intestinal integrity. Simply, the gut microbiota is the target to raise the health benefits and growth-promoting effects of feed additives on broilers. Therefore, naturally available feed additives are promising antibiotic alternatives for broilers.
The use of enzymes in animal feed was first reported in 1925 (Hervey 1925) but the chemistry of target feed substrate has been understood during the last two decades only. The field of biotechnology has introduced various advancements in enzyme production technology specifically in fermentation and microbiological processes resulting in production of enzymes in affordable range to be used for commercial purpose. The advances also include development of enzymes that are stable during...

In healthy humans and animals, protection against the harmful effects of free radicals is achieved through maintaining a delicate equilibrium between the production of free radicals, that are needed for certain physiological processes, and their destruction through the antioxidant defense system. This equilibrium is called “the redox balance”....

In most regions, summer is around the corner and poultry farmers need to prepare the birds to combat the heat and hence stay productive. Adding a powerful yeast postbiotic can help broilers absorb nutrients more readily and keep cool. When the chicken is healthy and performing at its best, the bird is in a state of physiological equilibrium (homeostasis). When the animal is exposed to stressors, coming from external sources (such as heat stress) or internal sources (such as metabolic...

Broilers are grown in a highly controlled environment that has been developed over many years to promote optimal and efficient growth while ensuring animal well-being. One of the most prevalent issues in broiler production is the development of footpad dermatitis. This condition is characterized by the appearance of lesions on the footpads of broilers and can be seen early in the brooding phase and are exacerbated as the bird grows. While broiler house management conditions are...

It is well understood that the goal of broiler live production teams is to deliver a high-quality, target-weight broiler to the processing plant. Up to the initiation of processing, there are considerable resources; financial, management and time that are committed by the company to accomplish this goal. One of the most tragic situations to occur is the condemnation or downgrading of either whole carcasses or carcass parts in the processing plant. There are a wide variety of causes for this...

Introduction In recent years, there has been increasing concern over the indiscriminate use of antibiotics in livestock production due to the possible emergence of multi-drug resistance, dangers of environmental pollution and toxic residue in animal products (Diarra and Malouin, 2014; Alagbe, 2019). Consumption of animal products (meat, milk and eggs) with residues of antibiotics can actually have a negative impact on human health (Oluwafemi et al., 2021). Plants produce primary...

Do you believe that adding a flavoring agent to your broiler or layer feed will improve performance? Your answer is probably no, or that you really hadn't thought about it. The early history of feed flavoring and taste research for poultry reads much the same way. Initially, poultry producers and some researchers felt that chickens had no real sense of taste and that flavor was of no consequence in poultry feeding. However, an examination of the literature, while not yielding a unanimous result...

Introductions: Non-starch polysaccharides (NSPs) encapsulated in feed grains' cell walls contain valuable nutrients that may be wasted since some animals' endogenous enzymes cannot digest them. Xylanase feed additives degrade grain cell walls, releasing entrapped nutrients to the animal. The soluble portion of NSPs increase digesta viscosity, slowing the passage of feed through the digestive system and preventing an animal's natural enzymes from acting upon...
