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.

High stocking density and environmental factors such as acute heat stress, health challenges, bacterial or viral exposure, and mycotoxin-contaminated diets may cause serious stress of laying in modern intensive egg production systems. Laying hens under immunological stress are susceptible to pathogen infection due to an imbalance in immune response and cecal microbiota. Laying hens that are raised under the conditions of intensive farming and high stocking densities are exposed to...

1. Introduction “Feed-food competition” was defined as “the tensions and trade-offs between two alternative uses for edible crops: direct consumption by humans versus feeding livestock” (1). However, feed-food competition includes the use of production resources, such as land, wild fish, and water, and labor, capital, and ecosystem services. The allocation of these resources between all their possible uses is often determined by which end use is most...

Poultry is a homothermal animal, and its body covers with feathers to increase its cold resistance. However, Taiwan is an island that lies in the tropic of cancer, and the general climate is marine tropical. During summer, this mechanism is adverse to heat dissipation and causes heat stress. Heat stress is a familiar stress effect that will affect animals’ growth performance, productivity, and health. Heat stress affects livestock production results in increased demand for net...

Broiler production is an essential part of global poultry industry, and broiler meat is an important source of protein for human consumption. Spirulina platensis a blue-green alga and a multicellular prokaryote known for having many benefits as it contains a variety of nutrient that makes it excellent addition to broiler feed. The high protein, mineral and vitamin content in Spirulina p. help improve growth performance, meat quality, immune function, antioxidant status and gut microbiota...

1. Introduction In animal husbandry, antibiotics are principally used to prevent, control, and treat diseases. However, they have also been extensively used as growth promoters [1,2]; this practice has been banned in Europe and the U.S. [3,4] but is still widespread in other regions, especially in rural areas, where farmers tend to depend more on antibiotics. Various countries lack legislative measurements to control antibiotic use. Moreover, farmers are not appropriately...

Insect farming is water-efficient and reduces food waste while producing quality protein, making it a potential solution to food sustainability and food security issues. Black soldier fly larvae, as an excellent source of protein, calcium, and a bacteria-fermentable polysaccharide called chitin, is a promising poultry feed ingredient. A 20-week feeding trial was conducted to evaluate the effects of dietary inclusion of black soldier fly larvae meal (BSFM) on the gut microbiota and SCFA...

Canada’s broiler chicken industry has taken great steps to reduce the use of antibiotics in production. Chicken Farmers of Canada successfully implemented a plan to remove both Category I and II antibiotics for preventive use from broiler feeds. There may be benefits from similar products for birds raised for egg production. Our research team has been involved in the evaluation of feed ingredients of marine origin. Seaweeds available off the Atlantic Coast of Canada were incorporated...

Woody breast (WB) and white striping (WS) in broiler breast meat are emerging issues in the poultry industry worldwide. These conditions are associated with high breast yielding, heavy broilers, and they have negative quality impacts and major economic implications. Nutritional strategies have been studied by researchers in efforts to reduce the prevalence of WB in broilers, without negative impacts on live performance. Dietary inclusion of guanidinoacetic acid (GAA) has been evaluated as a...

The formation of a viscous gut content in the small intestine due to the presence of non-starch polysaccharides in feed can markedly restrict efficient nutrient digestion in poultry. This adverse effect may be mediated through the supplementation of exogenous feed additives. The present study investigated the effects of carbohydrases and a buffered formic acid on growth performance and ileal digesta viscosity in broiler chickens fed a wheat- or maize diet. A 2 × 4 factorial arrangement...

Oregano essential oil (OEO) and carvacrol, the main compound of OEO, are considered as a reference for biological activities of essential oils (EO). OEO has positive effects on gut and immune system developments potentially related to antimicrobial and antioxidant activities in chickens (Brenes and Roura, 2010). Embryonic development accounts for one-third of the lifespan of modern broiler chickens, and has the potential to determine performance in later life. In-ovo injection is a powerful...

I. INTRODUCTION Maintenance of intestinal integrity is of fundamental importance to the overall health and growth performance of the bird. Disturbances in the homeostasis of the gastrointestinal tract can result in inflammatory process, loss of intestinal integrity, low nutrient digestibility and poor growth performance. In a situation of intestinal inflammation, pro-inflammatory interleukins such as interleukin-12 are produced with the objective to defending the host from any...

Coccidiosis is a disease with substantial economic impact (Muthamilselvan et al., 2016), particularly due to the push to ban anticoccidials. Vaccines are available but can be expensive, and are often implemented for free range and breeder flocks only. Thus, it is imperative to find effective nutritional alternatives to reduce the impact of coccidiosis on broiler chickens. The aim of this experiment was to determine if the nutritional strategies of post-pellet whole wheat (WW),...
