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 dynamic complexity of the developing embryo requires the maintenance of differentiated compartments with the capacity to maintain independent environments required to optimise their function. One of the least understood homeostatic mechanisms in embryonic development relates to the pH. The albumen’s pH at lay experiences a sharp increase to 9.7 which later decreases to 6.90 by day 17 (Tona et al., 2001). In contrast, the pH of yolk starts with a relatively low 6.67 at lay and...

The aim of this study was to evaluate the impact of feeding xylo-oligosaccharides (XOS), xylanase (XYL) and fermentable fibre, in the form of wheat bran (WB), on egg quality. It is theorised that WB stimulates and trains the microbiota in the hindgut to hydrolyse and ferment dietary xylan, and XOS and XYL may further upregulate xylan fermentation pathways, resulting in improved nutrient utilisation and thus egg quality. Isa Brown hens (n = 96 hens) were obtained at peak lay (39 weeks of age)...

I Introduction The development of reduced-crude protein (CP) diets for broiler chickens holds several potential advantages including reduced dependency on imported soybean meal by the Australian chicken-meat industry. Typically, reduced-CP diets contain less soybean meal but more feed grain (and starch) and more synthetic/crystalline amino acids. However, reducing dietary CP from 200 to 150 g/kg in isoenergetic diets has been shown to depress body weight gain, impair food conversion...

Professor Ian Godwin’s invited presentation focused on the use of gene editing and genetic modification techniques to improve the protein content and digestibility of sorghum for use in poultry feed. Sorghum is used to produce a range of human food and beverages and is the main summer grain produced in Australia. Sorghum copes well with the unpredictable Australian climate (heat, droughts, floods). Cereals make up more than 60% of poultry feed and sorghum is an excellent feed...

This study was to investigate the effects of Ganoderma lucidum fermented products (GLFP) on the growth performances, carcass characteristics, and immune response of Native chickens. This article focuses on the morphology of the duodenal villus by the Ganoderma lucidum fermented products (GLFP). A total of three hundred and twelve day-old Native chickens were randomly grouped with equal sex in four groups for three replicates as following treatments: (1) basal diet...

Conclusion To optimise oxidative status in broilers under challenging environmental circumstances, high levels of antioxidants are required to counteract the negative effects of reactive oxygen species. The addition of either 15 mg/kg vitamin E or 15 mg/kg Selko AOmix to broiler diets containing 10 mg/kg vitamin E diminished an increase in plasma malondialdehyde (MDA) levels (a marker for oxidative status) that may occur in animals in conditions where heat challenge is expected....

I. INTRODUCTION Forecasting is fraught with difficulties associated with poor data and unknown unknowns. Fortunately, in the case of laying hens, this is not true. We have an excellent history of how our birds have improved over the past decade (Table 1), and a fair idea of what can be expected in future breeding programmes used by the primary breeding companies. Our understanding is that the requirements for energy and protein per unit of output have remained unchanged and that...

The world is currently experiencing a high cost soybean meal environment, driven by multiple factors including supply-demand disruption due to ongoing transportation congestion, escalating input prices such as fertilizer, as well as supply-demand imbalances due to geopolitical conflicts. Together these factors have pushed soybean meal prices to levels not seen in many years (See Part I). This price pressure has led many feed producers to evaluate the use of non-traditional soybean products...

Introduction Poultry productivity depends on the combined effects of several factors such as the level of nutrients in feed, proper management practices, and the health status of the birds. To keep the enteric infections under control and promote growth, the supplementation of antibiotics in the poultry feed has been a regular practice. However, the use of antibiotic growth promoters (AGP) is restricted or banned in several countries due to the public health concern of...

Introduction Lipids are the primary source of energy for animals, and the digestibility of fats determines the amount of energy that can be obtained by an animal from dietary fat. The age of birds influences the digestibility of fats and poor absorption is a problem in very young birds. The absorption of dietary fat is physiologically restricted in young animals due to low levels of natural lipase production and low rates of bile salt generation (Tancheroenrat et al., 2014)...
