A vaccination programme combining a live attenuated Salmonella Typhimurium and an autogenous inactivated Salmonella Enteritidis vaccine confers protection and reduces ovarian colonisation with the Salmonella Enteritidis isolate 7A, PT12

Australian Veterinary Journal, EarlyView.
Salmonella enterica serovar Enteritidis (SE) can colonise chicken ovaries and contaminate eggs, posing a global risk of human gastroenteritis, often linked to raw or undercooked eggs. Control options for SE outbreaks in Australia are limited; autogenous SE vaccines are commonly used, while live attenuated Salmonella Typhimurium (ST) vaccines are ...

Early-age heat exposure improved growth performance and heat tolerance in broilers

Poultry Science
: A total of 440 one-day-old healthy male Arbor Acres broilers were equally assigned to a control group (CTL) and an early-age high-temperature exposure (EHT) group (4 replicates per group, 55 chickens per replicate).

Mechanical harvesting of broilers

Poultry Science, 1998
At the end of the growout phase of broiler production essentially all broilers are caught and loaded into coops or cages entirely by hand. The catching of broilers remains one of the few aspects of broiler production not yet automated. Vacuum systems, permanent conveyors recessed in the floors of growout facilities, collecting mats, scoops, and self ...

Effects of high ambient temperature on the community structure and composition of ileal microbiome of broilers

Poultry Science, 2018
The intestinal microbiome has been shown to influence animal nutrient metabolism and immune homeostasis. The present study aimed to examine the effect of heat stress on the intestinal microbiome of broilers using pyrosequencing technologies.

Haematological and histopathological monitoring of monosodium glutamate–supplemented feeding in rainbow trout (Oncorhynchus mykiss): A possible modelling for a single health approach

Journal of Fish Biology, EarlyView.
Abstract The aim of this study was to investigate the potential effects of monosodium glutamate (MSG), a known flavour enhancer added to many ready‐to‐eat foods, as a feed additive in rainbow trout (Oncorhynchus mykiss). Evaluating the effects of MSG on aquatic organisms will fill the knowledge gap in this field by monitoring the haematological indices

Rethinking our understanding of the pathogenesis of necrotic enteritis in chickens [PDF]

, 2009
For decades, low doses of antibiotics have been used widely in animal production to promote growth. However, there is a trend to reduce this use of antibiotics in feedstuffs, and legislation is now in place in Europe to prohibit their use in this way. As

Current Trends, Future Prospects and Constraints of Whole Microalgae and Their Fractions as a Functional Feed Ingredient for Animals

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Microalgae are a highly diverse group of unicellular organisms that grow in a wide range of aquatic environments and are widely used as dietary supplements for both human and animal applications. Microalgae are rich in lipids, proteins, carbohydrates and other valuable bioactive components such as pigments, antioxidants and vitamins.
