Introduction High levels of production and efficient feed conversion are the need of the modern livestock industry which to a certain extent could be achieved by using specific feed additives. Feed additives are of great interest in the poultry industry due to their property to promote growth and performance. Common feed additives used in poultry diets include antibiotics, antioxidants, emulsifiers, binders, pH control agents and enzymes. Antibiotic feed additives as growth...

Introduction Summer and Disease The mercury is soaring high throughout the country, and it seems there is no respite soon. High environmental temperature leads to heat stress. Heat stress can lead to various harmful impacts on livestock productivity, such as high animal morbidity, mortality, and reduction in growth performance, directly resulting in dramatic economic losses to the livestock industry. Heat stress and transportation or shifting from EC shed to the...

Poultry diets are usually required to supply high nutrient and energy concentrations in order to meet the nutrient requirements of modern intensively reared birds. Commercial poultry feeds are frequently added with fats and oils to fulfill the energy requirements of poultry and to give high energy to support the growth performance (Blanch et al. 1996). Dietary fats and oils offer 2.25 times more energy than carbohydrate and they are also supplier of essential fatty acids and fat soluble...

Introduction In poultry production systems, feed represents between 70 and 80 % of production costs; energy, protein, and amino acids are limiting factors that significantly affect the poultry industry’s feed costs and performance (Cancherini et al., 2005). The availability of the synthetic amino acids methionine and lysine in poultry feeds allowed lower protein levels since these amino acids limit portions for chickens and hens (Ramírez & Gonzalez,...

Introduction Modern broiler chickens are most certainly a most visible manifestation of genetic advancements. At hatch, a Cobb500 broiler weighs 42 grams. This newborn chick grows 31 % (55 g/bird) in just twenty-four hours. By day 35 of age, this chicken reaches a body weightof 2,521 grams, representing 5,902 % relative to hatching mass (Cobb-Vantres 500, 2022). Genetic selection, food, health, and management measures carried out intensively have resulted in these successes....

Soybean meal prices have been strong for nearly 2 years due to numerous factors such as pandemic fueled stockpiling, bullwhipping of supply/demand dynamics linked to asynchronous market reopenings and elevated input costs due to gross inflationary pressures. In this time, some regions have seen 100% increases in their local SBM prices - which has prompted a search for less expensive protein sources for their feeding programs. In Canada and parts of Europe, this has led to an increase in the...

I. INTRODUCTION Cereal grains such as wheat, sorghum, barley and maize are commonly used in poultry diets as the main source of energy. Knowledge on the metabolisable energy content of cereal grains is critical for their efficient use and precise poultry feed formulation. Despite several limitations (Mateos et al., 2019; Wu et al., 2020), the AME has been the globally accepted system for describing the dietary energy content for poultry. Modern, commercial broiler...

Introduction Since the major part of costs in poultry production is related to feed, minimizing this part of the costs which depends on feed ingredients is very important. On the other hand, phosphorous is usually one of the expensive nutrients in poultry feed. Therefore, the amount of nutrients in feed ingredients, especially available phosphorus, has a very important role in lowering the cost of feed. The main form of storage of phosphorus (P) in plant feedstuffs is phytate...

1 Introduction Copper (Cu) is a crucial trace element in animals; however, it cannot be stored in the body, thus, a regular dietary supplement is required. In addition, feed ingredients are commonly deficient in Cu; hence, the commercial diet should provide the essential amount of Cu in a biologically dynamic form, which depends on the physical and chemical properties of the form of the supplement in which the Cu is given in the diet [1]. Cu sulphate (CuSO 4 ) is...
