A guide to choosing the right ventilation concept for your farmIn this guide, you’ll read about the different ventilation concepts used in poultry and pig housing around the world. A ventilation concept is how you position air inlets, chimneys, fans, etc. in the barn. When we look around we see that every house or farm is different and you will find that there are variations on these concept ...

IntroductionMost of the population in the tropics depend on poultry as their significant source of protein supply. The harsh climate conditions in this region are making it harder to have optimal performance in poultry production. This results in a lesser everyday supply of protein. In the past few years, poultry production has had an important role in the global agricultural industry. Asia, South ...

INTRODUCTIONCorn and soybean meal are ingredients that have a good digestibility, however depending on the storage, crop and variety, these ingredients may have a change in their nutritional quality. For broilers, these ingredients constitute around 70 and 30% of the diet, respectively. Thus, any small improvement in their quality significantly influences the performance of the broiler chickens an ...

In most regions, summer is around the corner and poultry farmers need to prepare the birds to combat the heat and hence stay productive. Adding a powerful yeast postbiotic can help broilers absorb nutrients more readily and keep cool.When the chicken is healthy and performing at its best, the bird is in a state of physiological equilibrium (homeostasis). When the animal is exposed to stressors, co ...

INTRODUCTIONAs a nonpolar amino acid, Valine (Val) is one of the most hydrophobic amino acids (Brosnan and Brosnan, 2006). Val, leucine, and isoleucine are called branched chain amino acids due to the branched chain structures of their R groups. In animals, Val serves as a precursor for the synthesis of protein and other amino acids (Ferrando et al., 1995). As a glucogenic amino acid, Val is a sub ...

IntroductionCalcium reduction and phytase supplementation were considered an important combination in broiler nutrition. Wooden breast (WB) has been considered one of the most important challenges in the Poultry Industry in the 21st century. The superdosing of phytase can affect metabolic functions in the early life of broilers, and the studies with the interaction of this enzyme with calcium, pho ...

Dietary fat and oil are potential alternative energy sources for fast growing broiler chickens (Meng et al., 2004). Nevertheless, hampered fat digestion and absorption were reported in young broiler chickens with incompletely developed digestive tract (Al-Marzooqi and Leeson, 2000). Addition of emulsifier and lipases to a diet is one strategy to improve energy utilization and subsequent growth per ...

When it comes to controlling both the environment within a poultry house and heating costs during cold weather, house tightness is of utmost importance. This is because only the air that exhaust fans draw in through a house’s air inlet system will be heated and dried by the warm air collecting near the ceiling before moving down to floor level. Cold air that enters through cracks will tend t ...
