A 50,000 population of broiler in a tunnel vent would require about 50 KVA of power per day which includes electricity for the big exhaust/ventilation fans, motors for the pads, water distribution motors and submersible pumps, hundreds of lights inside and perimeter outside the tunnel vent housing, sensors and others. The projected savings in solar power conversion is at least 30%. The set up is grid-tied. The required power at night will be through the grid. All-day power needs would be...

Introduction All living organisms depend on the continuous supply of available phosphorus (P) sources for a plethora of metabolic processes. Fertilizer and feed phosphates are obtained to a large extent from rock phosphate. This is a non-renewable resource, and the global distribution of rock phosphate reserves is not uniform. Concurrently, P accumulation in areas with high livestock production density may be harmful to the environment. Hence,...

Introduction Animals used for food production have been genetically selected for feed intake and muscle development (or milk and egg production) and are therefore divergent from their ancestors. In addition, these animals are reared in conditions that favor fast spread of pathogens. The high uptake of feed and the fast growth make these animals prone to intestinal disorders, what has been neglected in the past because of the use of low doses of...

The best part of brunch? Rich, melt-in-your-mouth egg yolks.
Egg yolks are nutrient-dense and the main source of an egg’s flavor. Hens make egg yolks of different sizes, but larger yolks can mean that a hen has a lower feed efficiency—the ability to convert what it eats to egg yield.
Luckily, new genomic sequencing tools may make it possible to devise new breeding strategies to improve egg yolk size without requiring more...

For broiler chickens, how much space each bird gets around a feeder may be an important factor in weight gain and overall productivity.
According to a new Journal of Applied Poultry Research ® study led by scientists at Mississippi State University and the USDA-ARS Poultry Research Unit, increased feeder spacing can help growing broiler chickens get off to a good start—but these improvements don’t appear to translate to...

INTRODUCTION Soybean meal (Glycine max) is a widely used ingredient in livestock feed for its excellent protein content. Its production in Mexico is for use in the livestock industry, and is limited by the small scale of domestic soy bean production. Only 3 % of soybean meal demand is met by domestic production, the remaining 97 % coming from imported raw material(1). Despite its excellent protein content, its antinutritional factor content means soybean meal can only be used as...

1. Introduction The food demand is projected to double over the next 50 years [1]. The increase in the demand of poultry meat over the past decade has been due to the low cost, the positive nutritional profiles, and the suitability in farming [2]. Intensive production is required to achieve the demand, and poultry health should be approached in a multidisciplinary way to ensure animal health [3]. According to OIE, an animal is in a good state of welfare if it is healthy,...

1. Introduction Salmonella spp. are major food-borne pathogens around the world. The Salmonella genus is composed by two species, S. bongori and S. enterica. Also, the latter is also composed of six subspecies: S. enterica (I), S. salamae (II), S. arizonae (IIIa), S. diarizonae (IIIb), S. houtenae (IV), and S. indica (VI) [1]. In the year 2015, S. enterica was responsible of 94,625 confirmed cases of salmonellosis and 126 deaths in the European Union (EU). Although in the last...

One benefit of low protein (LP) diets is improving gut health in a future of antibiotic-growth promoter free diets. Drew et al., (2004) found an interaction between dietary crude protein (CP) and proliferation of Clostridium perfringens, a pathogenic bacterium identified to cause clinical and sub-clinical necrotic enteritis (NE), which costs the poultry industry US$6 billion dollars annually (Wade and Keyburn, 2015). Keerqin et al., (2017) observed improvements in body weight with excess...

INTRODUCTION Pelleting is the most common form of thermal processing used in broiler feed manufacturing, aggregating the particles of ingredients into a cylinder by means of mechanical pressure, moisture, and temperature. A wide range of temperature and moisture can be used during conditioning, usually from 60°C to 100°C and 12 to 18% moisture (Hancock, 1992). Increase in feed intake (FI) is among the main reasons that motivate agroindustries to pellet feeds...

INTRODUCTION The physical form of the diet is a tool to improve broiler live performance, especially feed efficiency. However coarse feed particles enhance gizzard function, which was referred to as the pacemarker of gut motility (Xu et al. 2015a, Xu et al. 2015b, Kheravi et al. 2017). Studies respect to particle size impact on health, digestive efficiency and broiler performance were developed more than 60 years ago (Pacheco et al. 2014, Xu et al. 2015a, Xu et al. 2015b)....

Introduction: Due to the constant genetic evolution in both the production of broilers, nutritionists must constantly adapt their nutritional recommendations and feeding programs to maximize economic results at all times. These management and nutrition decisions must take into account: the animal (potential for growth), environmental conditions and the composition of the feed, which affect feed consumption and, consequently, the performance of birds. And economic...

Introduction Soybean [Glycine max (L.) Merr.] meal (SBM) is typically the main protein feedstuff included in livestock diets (Félix et al., 2010; Oliveira et al., 2020). After being subjected to an adequate heat treatment, SBM has a high crude protein content, as well as a high digestible energy and low fiber contents (Félix et al., 2010). In general, SBM makes up 30% of broiler diets (Duarte & Junqueira, 2013). However, broiler performance is strongly...

INTRODUCTION Under current production systems, turkeys have traditionally been protected from pathogenic microorganisms by vaccination and antibiotics. For decades, subtherapeutic doses of antibiotics have commonly been used within the poultry industry to improve production performance and reduce pathogenic microbial challenges. However, negative consumer perception and increased regulatory guidance prohibiting the use of growth promoters or antibiotics within the animal...

INTRODUCTION The inclusion of fats and oils in broiler chicken diets is a common practice because they provide essential fatty acids, improved the absorption of soluble nutrients in oil and increased the content of metabolizable energy (ME) in the diets (Hossain and Das, 2014). Feeding programs are established based on EM needs, so nutritional strategies are sought to optimize productivity considering economic and environmental aspects during the production cycle (Andreoti et...
