Tryptophan, Serotonin & Melatonin Tryptophan (Trp) is an essential amino acid (AA), which is the building block of protein, therefore it cannot be synthesized by the body itself and must be obtained through food; it is important for many metabolic functions. Trp supplementation improves...

As a consumer of eggs, it's hard not to notice the spike in their prices. While we are still recovering from the increase in food costs due to the pandemic, eggs have become more expensive as well. The media has been abuzz with this issue. It's clear that rising food costs impact many people, with eggs being a staple in many households. Eggs...

Introduction The poultry industry aims to optimize the breast weight of the broilers because of its relatively higher market value. Through the years, improvements in breast meat yield have not only led to myopathies (Caldas-Cueva et al., 2021) but also to increased heat production (Martinez et al., 2019) due to the higher body protein content and turnover rates (Maharjan et al., 2020a; 2021b) in modern broilers. These conditions influence the feeding cost and the development of...

Deoxynivalenol (DON) is a major mycotoxin from the trichothecene family of mycotoxins produced by Fusarium fungi that cause disease in grains. Food and feed contaminated with DON cause a variety of adverse health effects in humans and farm animals. Fifty-four one-day-old broilers (Ross 308) were randomly allocated to three different treatment groups (n = 18 per group): ...

In order to guarantee the world protein supply, the key issues are the improvement in productivity and the efficiency of resources. Intensive poultry farming, being the only one used by all cultures around the world shows the best performance for eggs and meat production, as the main source of animal protein supply. Current poultry meat and egg production faces a permanent challenge to improve its productivity, including greater efficiency of nutritional and environmental resources to...

Mechanisms of Action for Phytase Enzymes in Poultry Diets for enhanced Phosphorus availability to Birds.? 1. Since first commercial utilisation, phytase has mainly been considered to be a tool to increase phosphourus (P) availability/digestibility from vegetable sources and so to reduce the inclusion of higher cost P sources. ?? 2. Here, phytase releases the P bound in the phytate molecule, increasing the availability/digestibility of this mineral to the animal. ? ...

Introduction Phytate: The latter part of the past century witnessed drastic increases in the size of poultry facilities for better efficiencies and lower production cost. Concurrently, fast-growing, or high producing breeds of poultry were developed and raised to utilize a plant-based feeds in their ration. But one of the major drawbacks of this ration is that it contains high phytate concentration making phosphorus unavailable to poultry, thus increasing the...

Introduction Optimizing the breast size of broilers is a critical economic target due to its higher market value versus other cut-up pieces. Historical improvements in breast production have shown an impact on the efficiency of broilers in using dietary energy (Martinez et al., 2019a), which accounts for 70–75 % of the poultry feed cost. They have also been associated with quality conditions such as white stripping, wooden breast, and spaghetti breast (CaldasCueva et al.,...

Introduction The branched-chain amino acids (BCAA) leucine, valine and isoleucine account for 35% of the essential amino acids in muscle protein and 40% of the total amino acid requirement in poultry [1]. Furthermore, The BCAA regulate protein synthesis and turnover in broiler chickens, facilitate glucose uptake by skeletal muscle, enhance glycogen synthesis and are important regulators of mTOR signalling pathways [2,3]. Indeed, leucine was identified as a possible regulator of...

1. Introduction The use of a low-crude-protein diet fortified with essential amino acids is a part of a precision feeding and has gained commercial acceptance to improve protein utilization, minimize environmental impact and thus increase the sustainability of broiler production, because it reduces the cost of production [1–3]. Protein accounts for the second most expensive nutrient in poultry diets, following metabolizable energy [4,5]. In the typical corn–soybean...

INTRODUCTION Repercussions of Coronavirus disease 2019 outbreak (currently known as COVID-19) on future global health are still being investigated, including the pandemic’s potential effect on the emergence, and spread of global antimicrobial resistance (AMR) [3]. According to World Health Organization (WHO) data, AMR causes about 700,000 deaths annually, which has been estimated to increase reaching 10 million deaths worldwide by 2050 [24]. The post-COVID-19 study is expected...

Poultry scientists find that Asp+Asn, Glu, or Glu+Gln supplementation can partly make up for low crude protein levels in male broiler chicken diets
A new study led by poultry scientists at the University of Hohenheim suggests it is possible to reduce crude protein in broiler diets while still encouraging bird growth—as long as birds receive supplementation with several “nonessential” amino acids....

Poultry researchers show there’s no safe amount of moldy corn
Poultry scientists are taking a close look at moldy corn in an effort to better protect animal and human health. In a recent study, published in Poultry Science ® , researchers measured bird performance and examined mycotoxin levels when laying hens were fed different amounts of moldy corn.
Mycotoxin are toxins made by...
