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.
Soybean meal prices have been strong for nearly 2 years due to numerous factors such as pandemic fueled stockpiling, bullwhipping of supply/demand dynamics linked to asynchronous market reopenings and elevated input costs due to gross inflationary pressures. In this time, some regions have seen 100% increases in their local SBM prices - which has prompted a search for less expensive protein sources for their feeding programs. In Canada and parts of Europe, this has led to an increase in the...

Due to the vast expansion of poultry industry challenges also increases. One of them is the control of microbial population which is done by excessive use of therapeutics antibiotics and AGP’s. The indiscriminate use of these products results in the emergence of antibiotic resistance. Apart from resistance it also leads to public health concern. Due to this EU has banned the use of AGP’s in 2006. After that, researchers found different ways to combat the problem of microbial...

INTRODUCTION In South Africa and worldwide, the poultry sector contributes immensely to the global food security status of consumers (1). According to the Food and Agriculture Organization (FAO) (2), the demand for poultry feeds is increasing due to the high growth of commercial and smallholder poultry enterprises. Moreover, in the poultry sector, feed accounts for approximately 60–80% of the total cost (3), with fish and soybean meal used as the main protein sources. However,...

Cordyceps militaris is a well-known Chinese medicinal fungus that has been used as a nutraceutical food in several Asian countries. Cordycepin (3’-deoxyadenosine), a secondary metabolite produced from Cordyceps militaris has been demonstrated to exert a wide spectrum of pharmacological activities, such as anti-microbial and antitumor activities. However, the effect of cordycepin on immunomodulation in broilers is poorly investigated. In the current study, we...

The genetic potential of modern broiler strains can only be exploited by focusing on their changed nutritional requirements. Feed is the most important aspect of poultry production which is primarily based on corn and soy, but the cost of feed ingredients for poultry diets continues to rise due to increased demand and decreased availability. This has resulted in rise in conventional feed formulations, making it important to understand the composition of alternative feed ingredients. The cell...

I. Introduction A consistent definition of aging was presented by DiLoreto and Murphy (2015). According to these authors, aging is the result of the non-functionality of the animal's cells, tissues and organs, caused by the stochastic degradation of its parts. This definition considers the changes that have occurred in laying hens that affect the rate of lay (Gu et al. 2021a, 2021b). The main changes are related to the digestive, reproductive system, endocrine glands and...

1-Monoglycerides of short and medium chain fatty acids (monobutyrin, monocaprin and monocaprylin) have shown positive effects on cell metabolism, intestinal integrity and immune system (Calder 2008). However, little is known about their effect on laying hen health, performance and egg quality. Therefore, this study was designed to add further insight into the applied benefits as well as optimal inclusion level of 1-monoglycerides of butyric, capric and caprylic acid on hen performance, their...

The use of antimicrobials in agriculture including broiler production is cause for concern due to the development of antibiotic resistant pathogens affecting both farm animals and humans (Marshall and Levy, 2011). Essential oils (EO) have been considered as promising alternatives to antibiotics. The aim of this study was to establish a standard in-ovo intervention using oregano EO to enhance resilience of new-born chicks against pathogens without compromising post-hatching performance. One...

I. Introduction The World Health Organisation has raised concern regarding increasing antibiotic resistance to commonly used antimicrobial drugs. In response, the use of antibiotic growth promoters in livestock production is being reduced each year, directed either by local government legislation or the pressure of consumer preferences. The objective of this study was to evaluate the effectiveness of several active compounds in maintaining bird health and performance when an...

I. Introduction Ingredients other than in-feed antimicrobial compounds can offer a sustainable approach to improving gastrointestinal (GI) health and animal performance. Efficient egg production and egg quality are of major importance to the poultry industry, but their optimisation is dependent on numerous factors. Nutrition and disease factors are among the most common factors affecting egg production and quality (Roberts, 2004). It follows that a healthy GI tract is required for...

An estimated 7.3 million tonnes of food waste are dumped annually in Australia, leading to substantial environmental and economic losses (Arcadis, 2019). Additionally, poultry feed represents the majority of production cost. Therefore, an experiment was designed to evaluate food waste as a feed for laying hens. A total of 150 Isa Brown laying hens at 24 weeks of age were allocated to 3 treatments (50 replicates per treatment) on the basis of body weight to maintain uniformity between the...

INTRODUCTION For many years now, the formulation of least cost diets to maximize poultry production has been the focus area for feed compounders and animal producers around the world. Formulating inexpensive high-quality feeds requires highly nutritious ingredients that are easily accessible and whose market prices are low. However, over-reliance on maize and soybeans as major ingredients during diet formulation contributes to high feed costs due to their exorbitant market...
