American and European companies are pledging to move to include slow-growing broiler chickens for production, which means they will use broiler chickens with less efficient growth rates in their production systems. Slow-growing strains show improved welfare outcomes compared to conventional ones. This newsletter...

Poultry scientists offer an approach for more accurate predictions of immune system function in birds
New research suggests poultry breeders can boost immune system function in birds by updating their prediction models to include “non-additive” genetic effects. The new study, published in The...

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....

Innovative Directions in Aflatoxin Testing Point to Measureable Gains in Quality Of Lab Data
Suggested link
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...

New Generation of Water-Soluble Probiotics to Alleviate Gut Health Challenge During Feed Transition Period in Broiler Production
Suggested link
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...

Introduction Ergot alkaloids (EA) are a group of compounds produced primarily by fungi of the Claviceps and Epichloë spp. Ergot infection has traditionally been associated with grasses and rye, however when conditions are favourable, other important cereals such as wheat, barley, triticale and oats can become infected. The fungus prefers cool, moist conditions during the flowering phase of the host plant and there is evidence that the incidence is increasing. For example, in a...

The commercial poultry industry is concerned about the continued spread of Avian Influenza (AI) and is closely watching as this disease is found in more countries around the world. Almost daily we receive reports that there are more outbreaks here or there in different media. We see these reports in digital newspapers, television, radio, and this time we are bombarded with more ads on WhatsApp, Twitter, Facebook, TikTok, Instagram, Telegram, etc. In many cases, we do not know the source of...

Introduction The poultry industry has experienced unprecedented growth in the past 70 years due to improved genetics, nutrition, housing, water quality and veterinary care driven by post-WWII consumer demands (Havenstein, et al., 2003). Modern-day poultry efficiently convert feed to meat and eggs, but genetic selection for improved performance may have inadvertently selected for a negative correlative response to other traits such as immune function (Cheema et al., 2003). The reader...

Great topic! That will be a robust energy system to chase NE for maintenance and production. So far, there's been an ongoing debate among researchers on whether the poultry industry would benefit from a NE system over the ME system due to the following challenges:
1. Inconsistent definition of NE
2. Challenges regarding measuring heat production (Sources of heat are confounded; Non-feed factors can affect heat production)
3. Data lacking
Thanks to the precision feeding technology, more data are...
