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.

Glucagon-like peptide (GLP) is one of the major intestinal hormones and has two subtypes, GLP-1 and GLP-2. GLP-1 is a 36-amino acid peptide released from intestinal L cells in response to ingested nutrients [1]. In the gut, this peptide hormone performs a variety of physiological and biological roles. Some of these functions include enhancing glucose-dependent insulin release, inhibiting glucagon secretion, increasing pancreatic β cell growth [10, 27], decreasing food intake [1],...

Deoxynivalenol (DON; vomitoxin) is a trichothecene mycotoxin that is produced by Fusarium graminearum (F. graminearum) and is prevalently found in grains such as wheat, corn, barley and their by-products. Food and feed contaminated with DON cause a variety of adverse health effects in humans and farm animals. Poultry are also adversely affected by DON but less susceptible due to differences in DON metabolism. Because of the differences in breeds, types of diet and strains of poultry,...

Introduction Controlling production costs and animal welfare are important factors for breeders. Feed accounts for 50 to 70% of the production cost in poultry production (van Horne, 2018). The feed conversion ratio (FCR), which is the ratio of feed consumption to meat or egg production, is an important criterion for the profitability of these farms. It is also an indicator of the environmental impact of production. For example, the reduction of 10% in FCR results in a reduction...

Copper (Cu) has been widely used at pharmacological levels (e.g., 125 ppm) as growth promoter in poultry. However, the mechanism by which high levels of Cu promote growth remains to be determined. It is commonly recognized that Cu exerts anti-microbial effect in the gut but there is not much direct and consistent data showing that Cu alters the population of bacterial species in birds. And copper can maintain proper body functions and obtain the optimal growth performance of poultry (Banks...

1. Introduction Taste perception influences feed intake guiding nutrient choices [1,2]. It has been widely assumed that the sense of taste in avian species is not as accurate as in mammals, as they have fewer taste buds [3]. However, the ratio of taste buds to oral cavity volume in birds appears to be higher than in most mammals [4]. Recent behavioural and genomic studies have found that birds have a highly developed sense of taste [1,5,6]. Poultry possesses a...

As producers reduce antibiotic use, scientists examine new strategies to improve bird growth and health
Poultry scientists are investigating new ways to keep birds healthy and shift the poultry industry away from widespread use of antibiotics. Researchers are especially keen to improve antimicrobial strategies for organically raised chickens, which are not given antibiotics.
According to a new paper...

INTRODUCTION Genetic selection in poultry has progressed continuously since the early 1960s, resulting in faster growth rates and higher meat production (Havenstein et al., 2003a,b). Over the past 60 years, body weight gain has increased fourfold from 1957 to 2005 with a simultaneous 50% reduction in feed conversion ratio and 79% higher Pectoralis major yield in males and 85% in females (Zuidhof et al., 2014). At the same time, the growth, development, structure, and...

Field pea ( Pisum sativum ) is a good source of protein but can also provide energy due to high starch content (Petterson et al., 1997). The slowly digestible starch in pea may improve energy utilization in broilers because of the prolonged elevated plasma glucose levels (Enting et al., 2005). Thus, partial replacement of soybean meal and wheat with pea may affect the net energy value of the diet. This experiment was performed to investigate the effect of pea in diet formulation on...

I. INTRODUCTION Omega-3 PUFA (polyunsaturated fatty acids) are commonly known for their health benefits to the consumer. This family of essential fatty acids provides a host of health benefits. There are three types of fatty acids in the omega-3 family: alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Each of these omega-3 fatty acids is considered essential; however, not all...

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...
