Background Biofortifications of chicken with bioactive nutrients such as DHA and calcidiol [25(OH)D3] have been viewed as an effective strategy to produce health-promoting meat for human consumption [1, 2]. Relatively low to moderate inclusion levels of calcidiol (1600 to 2800 IU/kg diet) [3, 4] and DHA-rich microalgal biomass or oil (0.55 to 2.55 g DHA/kg diet) [5–7] in broiler diets caused no negative effects on growth performance, lipid profile of tissues, or...

Conventional broiler (meat) chickens reach a final weight of 6.6 lbs (3 kg) in approximately 40-44 days. Across their lifetime, these fast-growing birds gain an average of 68-75 g per day, with daily gain increasing with age (Aviagen, 2022; Cobb, 2022). With their fast growth, however, they...

A new study of elevated plastic platforms vs. wooden planks suggests turkeys can balance better on the platforms and prefer platforms overall
Poultry scientists work to make sure animal housing is safe—and they research how housing updates might benefit bird health and welfare. For researchers in Switzerland, one important question is whether fattening turkeys (raised for their meat) might benefit from...

As we replied earlier you need to enhance the nitrogen digestibility in the gut level more efficiently and there by depending on the substrates available in the poultry ration and through various biological studies these doses are recommended. In India, we use most protein sources from vegetative origin, only small percent of animal protein is formulated....

1. Introduction Aspergillus is soil fungal species that have been recognized as a major contaminant of different grains utilized for poultry diets [1]. They grow rapidly under high moisture conditions and produce biologically active hepatotoxic aflatoxins [2]. Maize, cereals like rice, wheat, pistachios, cottonseed, copra groundnuts, and many other feed stuffs are contaminated by these fungal species [3–5]. Aflatoxin actually covers three words in accordance...

Introduction Monogastric feeds are reliant on plant-based protein sources, like corn and soybean. However, increasing demands on these plant-based materials for non-food industries, such as biofuels, is also associated with an increase in the price of these feed ingredients, placing an impetus on the demand for these alternative protein sources (Leiber et al., 2017). Emerging areas of monogastric animal nutrition research include the use of insect meal, microalgae, single cell...

Introduction Mycotoxins are toxic secondary metabolites produced by fungi. They are unavoidable contaminants in foods and feeds, exerting harmful effects upon animal and human health 39 . The most important mycotoxins in naturally contaminated foods and feeds are aflatoxins (AFs), ochratoxins, zearalenone, T-2 toxin, deoxynivalenol and fumonisins 7,32 . Aflatoxin contaminated feeds are a severe threat to both livestock productivity and human health and cause...

Introduction The poultry industry aims to increase the breast weight of broilers due to its higher market price. However, the breast size is associated with meat conditions such as woody breast (Maharjan et al., 2021a), the body protein turnover (Maharjan et al., 2020a, Maharjan et al., 2021b) and lean mass weight (Martinez et al., 2020a), and changes in the partitioning of the dietary energy (Martinez et al., 2019a). These relationships can be influenced to favor production and...

Introduction In poultry, the net energy (NE) is the sum of the energy retained in the body and lost through heat production. Under its classic definition, the prediction of NE requires precise and accurate determinations of fasting heat production (FHP) and heat increment, which accounts for the energy production due to feeding, digestion, and the associated physical activity (Maharjan et al., 2021c). Then, the NE is indirectly obtained by sequential differences from the gross...

Introduction The global population is anticipated to reach around 10 billion people by 2050. At the same time the global middle-class is growing significantly particularly in high populous countries such as China and India. The combination of these two factors places significant pressure on global food systems which must be capable of providing food and nutrition security in 2050. The next 30 years are arguably one of the most critical transitions in human history as we approach a...
