Salmonella enteritidis (SE) accounts for more than 70% of spp. infections in humans with a primary source being chicken eggs, that can result from post-lay SE cross-contamination the shell contaminated equipment or environment. The objective this study was to apply HVACP treatment achieve minimum 5-log reduction on surface artificially inoculated eggs an initial bacterial load 108 CFU/egg, afte...

The aim of this study was to investigate the genetic and phenotypic correlations of egg quality traits in Khazak chicken. Albumen height (AH), albumen weight (AW), eggshell color (ESC), yolk color (YC), eggshell index, long length of egg (ELL), short length of egg (ESL), eggshell weight (ESW), egg weight (EW), Haugh units, and yolk weight (YW) were measured in 201 eggs collected 6 d sequentiall...

a eight-week trial was carried out to investigate the effects of various levels and type of organic selenium as compared to inorganic selenium. total of 81 layer hens (lsl) 35 weeks of age were used in a randomized complete blocks with 9 treatments, 3 replications of 3 birds per experimental unit. treatment diets included control 0/3 mg/kg sodium selenite and selenium yeast, (250 mg/kg, 500 mg/...

ABSTRACT: This study was done to determine the best value of total electrolyte balance (BET) concerning variables performance and egg quality laying hens. We investigated 240 Hy-Line Brown hens, 30 46 weeks age, adopting completely randomized experimental design, which included five treatments (1000, 1250, 1500, 1750 2000 μeq / kg), 8 repetitions 6 birds per unit. The birds’ eggs were evaluated...

Minerals are used widely as feed additives in the diets of poultry to enhance bone and egg quality productivity. Therefore, current study aimed evaluate impact strontium ranelate cerium oxide addition diet on production eggshell laying hens. In this experiment, a total 240 hens at age 44 weeks old, were divided into six treatments, with four replicates per treatment (10 replicate). The fed stan...

This study investigated correlations between egg quality indicators to identify external traits predict internal using non-destructive and convenient measurements. Thirteen indicators, including Haugh unit, albumen height, eggshell breaking strength, thickness, color (CIE L*, CIE a*, b*), reflectivity value, weight, length, width, shape index, yolk color, were i...

This study aimed to evaluate the internal and microbiological quality of eggs submitted different types shell treatments. One hundred forty-four fresh red were distributed in a scheme 4 treatments (no washing; washing immersion chlorine; peracetic acid; spraying propolis extract) x 5 storage periods (7, 14, 21, 28, 35 days), stored at 25°C, each period 6 per treatment analyzed. The parameters a...

The effects of L-carnitine supplementation (50-500 mg/kg diet) of a practical layer diet, based on maize, soyabean and wheat, on the performance of laying hens and some indices of egg quality were studied for 8 weeks, using 65-week-old hens kept in cages. Albumen quality (albumen height and Haugh (1937) unit score) was improved, while yolk index and yolk colour score were not affected by dietar...

The objective of this study was to evaluate egg quality and hatchability indigenous exotic chickens in the midland, lowland, highland agroecological zones Silte zone. One district selected from each zone, a total 399 households (133 district) were randomly chosen six purposefully Kebles collect data on hatchability. For external internal evaluation, 300 eggs (150 150 agroecology) collected. fou...
