INTRODUCTION Newcastle disease virus (NDV) is Avian avulavirus type-1 that belongs to the genus Avulavirus of the family Paramyxoviridae (Swayne and Glisson, 2013). Newcastle disease virus isolates vary in their pathogenicity to chickens and may include at least 3 pathotypes; lento-genic (low virulence), mesogenic (moderate virulence), and velogenic (high virulence). Velogenic NDV remain a major threat to the poultry industry because of high mortality and reduced egg production...

Mycotoxins are a group of structurally diverse secondary metabolites of fungi that occur as contaminants of grains worldwide. Aspergillus, Alternaria, Claviceps, Fusarium and Penicillium species of fungi are ubiquitous in nature and under ideal conditions often infect economically important crops during storage, shipment and processing. Many secondary metabolites produced by these fungi can cause serious health problems in poultry and their presence in agricultural commodities may result in...

In some companies, fertility and hatchability start to decrease during the last weeks of production, for example after 50 weeks, at the same time there is a loss of feathers in the back or there is an overweight of the egg. How can we improve fertility and hatchability in the last phase of production of broiler breeders? To improve fertility and hatchability we must evaluate three important points: (a) management of the roosters, (b) hen feather cover and (c) egg size. ...

Methionine belongs to the twenty amino acid making up proteins. It is an essential sulfur-containing amino acid. As essential aminoacid, It cannot be synthesized by the animal and its requirement should be supplied trough the feed. It is one of the first limiting amino...

1. Introduction In hot climates, the growth of broilers is usually slow, as high temperature adversely affects feed intake, and high-protein diets, used to sustain animal growth, may impair broiler tolerance to heat stress due to the high heat increment induced by protein metabolism [1,2]. Decreasing dietary protein levels of broiler diets could be a good strategy, but the amino acid requirements for broiler chicks must be satisfied by supplementing synthetic amino acids to the...

Presence of mycotoxins in feed is one of the major constraints in maintain feed quality because the mycotoxins are widely present in feedstuffs around the world and may affect production even in very low concentration. The most widespread and in most studied group of mycotoxins, aflatoxins are of great concern in warm and humid climatic conditions like India (Singh et al. 2010). Aflatoxin in poultry causes reductions in growth performance (Silambarasan et al. 2013, Patil et al. 2013),...

INTRODUCTION Consumer demand for eggs in North America has been steadily increasing, with retail growth of 6% in 2018 in Canada, up from the 4.1% growth seen in 2017 (Egg Farmers of Canada, 2017, 2018). In the United States, 2018 per capita egg consumption increased by 2.1% over 2017 (USDA, 2019). It is therefore critical to establish suitable nutritional and management strategies that accommodate these increased production goals, while accounting for the economic, social, and...

1. Introduction Escherichia coli is a Gram-negative bacterium that typically inhabits the intestine of vertebrates and is considered a usual member of the digestive flora in animals. However, under favorable circumstances, it may acquire genes associated with pathogenicity/virulence and cause clinical disease in most domestic farmed species. Colibacillosis is a systemic fatal disease, which occurs when an E. coli strain escapes digestive barriers and invades the internal organs....
