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.
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...

I. INTRODUCTION Modern broilers grow quickly because they have tremendous genetic potential due to intensive selection for increased growth rate and efficiency (Zuidhof et al., 2014). The parents, broiler breeders, carry this genetic potential and when fed ad libitum, easily become overweight (Heck et al., 2004), compromising reproductive performance (Renema and Robinson, 2004; Chen et al., 2006) and reducing welfare (Mench, 2002). Thus, broiler breeder hens are typically feed...

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...

Minerals such as copper, manganese and zinc are essential nutrients for enzyme functionality, immune system responses, tissue and bone quality as well as eggshell formation (Richards et al., 2010). Organic trace minerals are used in animal feeds to provide increased mineral bioavailability. In this experiment we investigated the benefits of hydroxy analogues of chelated trace minerals on pullet quality. Three hundred- and sixty day-old Isa Brown layers were randomly allocated into two groups...

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...
