In the practice of feeding poultry enzyme drugs are widely used that contribute to the effective transformation of feed components into poultry products. Reducing the cost of compound feed for poultry due to the introduction of enzyme drugs is of great interest, both from a scientific and practical point of view. More than 2/3 of phosphorus in plant feeds is represented in the form of phytate and in this form the element is only partially absorbed in the poultry body. Accordingly to cover the need for phosphorus in plant diets include inorganic phosphates, animal feed and the enzyme phytase (b

Since the digestive system of poultry is quite short, the residence time of the feeds in the digestive system is also short. In addition, many poultry species have a low ability to digest and utilize cellulose, cellulose fractions (ADF and NDF) and non-starch polysaccharides. Therefore, it becomes necessary to use more expensive feeds with high nutrient content in poultry nutrition. This situation raises the prices of animal products such as white meat and eggs. In order to turn this disadvantage in poultry feeding into an advantage, alternative poultry with a stronger digestive system, better

To assess the contamination and potential health risks for poultry, we investigated concentrations of selected mycotoxins in complete feeds sampled within the period of 2013–2018 in the Czech Republic. Broiler feeds, feeds for laying hens, chickens and/or other poultry species were investigated by ELISA methods or chromatography. Our results demonstrated that unlike other mycotoxins, (such as aflatoxins, ochratoxin A or zearalenone), deoxynivalenol (DON) may represent a potential threat. The prevalence of this mycotoxin in all the feed categories was very high, always reaching at least 81.29%.

Determining the energy values of feed ingredients for poultry is of great concern, especially since production efficiency is associated with profit margins. Therefore, accurate, precise, and reproducible energy values for feed ingredients are of the utmost importance in formulating an economical diet. An important aspect in determining the apparent metabolizable energy (AME) of a feed ingredient is the procedure employed in the drying of excreta samples. During sample preparation, substantial grinding losses were incurred amounting to 3.5 to 5.2% of the dried sample weight. Also moisture upta

AbstractGlobal climate change poses a great threat to poultry production. Greenhouse gases (GHGs) are released through both natural and anthropogenic sources into the atmosphere. Though poultry production contributes little to the release of GHGs, the subsector has been shown to be greatly affected by climate change and global warming. Poultry production as a major subsector of agriculture has provided the teeming population with a supply of needed animal protein in terms of meat and egg production all over the world. It is yet a major global employer of labor. Though it occupies a vantage position in meeting human needs, it is being threatened by climate change, especially in Africa where necessary structure to tackle the menace is nonexistent. Broiler chickens that are reared mainly for chicken meat cannot tolerate the high ambient temperature that prevails mostly in the tropical environment. Chickens are homeotherms that homeostatically regulate core body temperature within a narrow range. Elevated ambient temperature above thermal comfort zone, such as envisaged in climate change scenarios, will trigger series of neuroendocrine modulations that are detrimental to the welfare and productivity in broiler chickens. Such birds are said to be undergoing heat stress (HS). Negative effects of HS include reduced feed consumption, growth rate, feed digestion and efficiency, immunity, welfare, and survivability. Various adaptive measures that could be harnessed by broiler farmers, ranging from housing, feeding, watering, stocking, breeding for thermo-tolerant strains, thermal conditioning, use of phytochemicals, and much more, are reviewed upon in this chapter.

The output of poultry products by poultry enterprises in the world was mainly determined by feeding techniques and poultry productivity. The productivity of poultry is characterised by the rate of egg-laying or the number of eggs produced per hen a year and affected by the availability and diversity of feed materials (especially protein). In recent years, researchers have focused on legumes of various species as promising sources of protein for livestock production, such as beans, peas, lupine, alfalfa etc.; therefore, in Latvia more attention is paid to the production of protein crops or legu

In the Federal Scientific Center "VIK im. V. R. Williams” conducted research on the evaluation of new varieties of spring and winter colza Zarya and Nadezhda when growing broiler chickens of the Cobb 500 cross. The control group received compound feed without rapeseed seeds. The first and second experimental groups included 7.5% by weight of mixed fodder native rapeseed seeds of Zarya and Nadezhda varieties, which were used to replace part of soybean meal and sunflower oil. The content of nutrients in mixed feed complied with the regulatory requirements. The oil was balanced in composition: a

The paper presents the most important aspects of the action of exogenous enzymes (amylase, xylanase, glucanase, cellulase, hemicellulase, pectinase, phytase and protease) added to broiler feed. The addition of broiler feed enzymes has nutritional, health, economic and environmental justification. The use of complexes of exogenous enzymes (enzyme cocktails) as additives to complete mixtures for feeding broiler chickens in different phases of fattening, significantly increases the availability of reserve polysaccharides, fats, proteins and some minerals, better energy efficiency from food, bette

The fate of transgenic DNA (tDNA) and protein of feeds from Genetically Modified organisms (GMOs) in animals has been an important topic since their commercialization in 1996. Several studies have investigated about risks of horizontal gene transfer (HGT) of tDNA and proteins to bacteria or animal cells/tissues, however, the reported data is at times controversial. Earlier reports showed that tDNA fragments or protein derived from GM plants have not been detected in tissues, fluids, or edible products of farm animals. Other researchers have come out to demonstrate that there is the possibility

The poultry industry has advanced remarkably over the past 30 years. In particular, broiler production has been the most successful than any other sector in the animal industry. Production standards of broilers have continuously improved over this period, with modern broilers reaching a live average weight of 2.5 kg at 33 – 35 days. Today, under normal conditions, a broiler chicken can gain an average weight of 65 g per day and can attain 1.5 feed conversion ratio (FCR). Genetic selection brought about by breeding companies has played a big part in the improvements of broiler growth, and advan

The FAO has projected a doubling in world demand for seafood during the 21 ed from aquaculture of marine fish and shrimps fed primarily on fishmeal-based aquafeeds. However, current practices of high intensity monoculture of shrimp in coastal ponds and fish in offshore pens have been strongly criticized as being ecologically and socially unsustainable. This view derives from un- checked eutrophication of coastal marine ecosystems from fish farm effluents, and the destruction of coastal estuarine ecosystems by shrimp farm constructions, plus aquaculture’s reliance on wild-caught small fish - wh

Mortality in a broiler flock will typically range from 4-5% of the population over the course of 6- 7 weeks in the U.S. and 7-8% of the population in Israel. Suboptimal intestinal maturation and functionality are one of the major factors that contribute to early age mortality and hinder flock body weight uniformity. The development of absorptive and secretory functions is orchestrated by differentiation of cells that arise from stem cells. Supplying compounds by in ovo feeding (IOF) during late embryogenesis provides nutrients that may change the dynamics of stem cell differentiation. We hypot

The project was originally aimed at investigating and developing new efficient methods for cost effective removal of ammonia (NH₃) and hydrogen sulfide (H₂S) from Concentrated Animal Feeding Operations (CAFO), in particular broiler and laying houses (NH₃) and hog houses (H₂S). In both cases, the principal idea was to design and operate a dedicated air collection system that would be used for the treatment of the gases, and that would work independently from the general ventilation system. The advantages envisaged: (1) if collected at a point close to the source of generation, pollutants would
