Poultry egg quality
Egg quality defines those characteristics of an egg that affect consumer acceptability and preference. Components of quality include shell quality and interior egg quality for shell eggs, and interior egg quality for further processed eggs. The quality of the egg once it is laid cannot be improved. Hence, its maintenance is mostly a preventive process. Egg quality is influenced by several factors including rearing, temperature, humidity, handling, storage, and egg age. Shell quality: There are five major classes of shell defects: integrity, texture, shape, color, and cleanliness. Internal egg quality involves functional, aesthetic and microbiological properties of the egg yolk and albumen. The proportions of components for fresh egg are 32% yolk, 58% albumen and 10% shell. Regarding exterior egg quality, the shell of each egg should be smooth, clean and free of cracks. The eggs should be uniform in colour, size and shape.
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...

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...

The holiday season is once again here, which means many kitchens will be filling up with baked goods and savory dishes. It is also the time of year when the use of eggs increases for all of those delicious dishes! However, eggs can be a potential source of Salmonella bacteria that can cause illness or in rare cases even death. Here are some tips to...

Plant-derived essential oils (EOs) contain functional phytochemical components that are used as feed additives to improve gut health and reduce the need for antibiotics. The injection of EOs into fertile eggs has the potential to influence the developing embryo including the gastrointestinal tract. This in turn may mitigate intestinal susceptibility and regulate gut microbial composition, resulting in long-term benefits in the chicken's life. However, some gaps in the in-ovo injection...

I. INTRODUCTION Consumer demand for organic and free-range poultry products is driving the commercial egg industry away from conventional housing systems towards free-range housing systems that allow birds access to the outdoors. Whilst these systems are considered higher welfare, they also carry more health risks that can impact the intestinal health of the bird, such as greater exposure to parasites as reported by Permin et al., (1999). Intestinal helminths such as nematodes and...

I. INTRODUCTION With the recent COVID-19 pandemic disrupting the regular supply chain in agriculture and threatening food security, it is imperative to look for innovative ideas to meet the population's food demand (FAO, 2021). The agriculture sector is pressured to offer sustainable, economical, and ethically-produced animal protein. Egg, a cheap and relatively easy-to-produce commodity, is one of the best candidates for such protein. Thus, there is a surging increase in layer...

Duarte Neves (Zinpro) The poultry industry is facing a problem with the fertility of broiler breeder eggs. The use of elevated amounts of trace minerals such as zinc (Zn), manganese (Mn), and copper (Cu) within a broiler breeder diet has been previously linked to an increase in eggshell quality, which in turn may lead to an increased fertility rate. A parameter that has been linked to an increased eggshell quality is shell translucency. The...

Duarte Neves (Zinpro) This study aims to evaluate shell translucency as a novel eggshell quality parameter to predict hatchability of fertile eggs. A total of 22,140 eggs were collected from 738 broiler breeder flocks between 25 to 65 wks of age, from multiple commercial hatcheries in the US. Translucency was completed with Zinpro® BlueBox TM using a 3-point score system: TS1 = none or few small translucent spots; TS2 = several...

This study was designed to evaluate the efficacy of a new generation phytase, HiPhorius (HP), and protease, ProAct 360, when fed to peaking hens. Dietary treatments included Positive Control (PC), Negative Control 1 (NC1) at 0.15% nPP, NC1+600 FYT/kg HP, NC1+900 FYT/kg HP, Negative Control 2 (NC2) with a 2% crude protein (CP)...

Alin Khaliduzzaman (University of Illinois Urbana Champaign) Some of the continents and countries might suffer severe food shortage in the next few decades due to climate changes, global unrest, and economic instability. Therefore, we need major technological advancement for egg and poultry production industry to deal with global animal food security and poultry welfare issues. The current hatchery practices, post-hatch grading of day-old chicks,...

Mike Persia (Virginia Tech) Experiments were conducted to determine the bioavailability of fine ground aragonite (FGA) using 0-14 d old broilers and to determine the use of FGA on performance, eggshell quality, and tibia ash (TA) of laying hens from 28-56 wks. In experiment 1, 450 as hatched Ross 708 broilers were fed a basal diet without either LS or FGA containing 0.35% Ca and LS and FGA additions resulting in 0.43, 0.51, 0.59, and 0.67% Ca. Body...

I. INTRODUCTION Feeding the world’s projected burgeoning human population increase of 2.2 billion people by 2050 will place tremendous pressure on food security. The poultry industry is innovative and well positioned to address this problem through increased efficiency and waste reduction. Globally, 32% (by weight) of produced food − equivalent to 1.3 billion tons − is lost or wasted every year. Conversion of food waste into raw materials for production of poultry...

I. INTRODUCTION With ongoing genetic selection for improved persistency of lay and feed efficiency (FE) in laying hens, the egg industry is pursuing the opportunity to extend layer hen lifespan until they are 100 weeks of age (WOA), with an aim for each hen to produce up to 500 eggs. This presents some challenges for the hen as during this longer laying cycle she will be producing more than 31 kg of egg product (Muir et al., 2022c) and using approximately 1 kg of calcium (Ca) to...
