Overfeeding and underfeeding livestock and poultry can have significant impacts on their health, productivity, and overall profitability. The effects on animal performance and the economic importance of these issues are crucial for farmers and producers to understand in order to make informed decisions about nutrition, feeding practices, and resource management. Effect of Overfeeding in Livestock…
Innovations in silage and hay preparation are essential for improving the efficiency and quality of animal feed, ensuring better nutritional value, and enhancing the overall productivity of livestock operations. Here are some innovative approaches in the preparation of silage and hay: 1. Precision Harvesting and Mowing Technology: • Robotic Mowers: The use of autonomous mowers…
Spectrophotometry is a powerful analytical technique used to measure the concentration of mineral elements in biological samples, such as animal feed, tissues, blood, urine, and other fluids. This technique involves the measurement of light absorption at specific wavelengths, which is directly related to the concentration of mineral elements in the sample. Here’s an advanced procedure…
The Flame Photometer (FP) is a specialized analytical instrument used for measuring the concentration of metal ions in animal feed, biological samples, and animal tissues. It is commonly used for detecting alkali and alkaline earth metals such as sodium (Na), potassium (K), calcium (Ca), and magnesium (Mg), which are essential for animal health and nutrition….
Thin Layer Chromatography (TLC) is a widely used analytical technique in animal nutrition for separating and identifying compounds present in biological samples, such as feed, food, or animal tissues. The application of TLC in animal nutrition includes: 1. Identification of Nutrients: TLC can be used to separate and identify various nutrients in animal feeds, such…
Vitamins Vitamin A Role of Vitamin A • Synthesis of glycoprotein to maintain integrity of epithelial cells. • In bone formation synthesis of mucopolysaccharides. • Synthesis of the visual pigment Rhodopsin. • Retinol and retinoic acid (RA) are essential for embryonic development during fetal development. Clinical signs • Inadequate retinol available to the retina results…
5. Cobalt Role of Cobalt • Cobalt is required by microorganisms in the rumen for the synthesis of vitamin B12. • Cobalt acts as an activating ion in certain enzyme reactions. Clinical signs • Cobalt deficiency causes vitamin B 12 deficiency in ruminants. • Wasting disease or coast disease or Pining or Enzootic marasmus characterized…
1. Calcium: Role of Calcium: • 99% of the calcium in the body is present in the bones and teeth. • Calcium controls the excitability of nerves and muscles. • Calcium is required for normal clotting of blood. • Calcium is necessary for activation of enzymes like trypsin, adenosine triphosphatase. Clinical signs: • In young…
This system of analysis divides the food into six fractions: moisture, ash, crude protein, ether extract, crude fibre and nitrogen-free extractives. The moisture content is determined as the loss in weight that results from drying a known weight of food to constant weight at 100 °C.This method is satisfactory for most foods, but with a…
1.1 Water 1.2 Dry matter and its components 1.3 Analysis and characterisation of foods Food is material that, after ingestion by animals, is capable of being digested, absorbed and utilised. In a more general sense we use the term ‘food’ to describe edible material. Grass and hay, for example, are described as foods, but not…
The poultry industry is continuously evolving with new feeding concepts designed to improve poultry health, productivity, and sustainability. Here are some of the latest concepts in poultry feeding: 1. Precision Feeding • Concept: Precision feeding aims to tailor the nutritional intake of each bird based on its individual needs, such as age, weight, and growth…
Numerous factors have been identifi ed that infl uence the effi cacy of exogenous phytases, which is partially refl ected in the inconsistent responses to phytase that have been reported in the literature. An exhaustive consideration of all potential factors is simply impractical. To take one example, Leslie et al. (2006) reported that reducing the…
Notionally, phytases have the capacity to degrade IP6 phytate completely to inositol and to liberate six P moieties. However, because the P moiety axially located at C2 is not readily released, complete dephosphorylation of phytate by phytase probably does not occur in pigs and poultry. By contrast, there is a possibility that endogenous phosphatases (associated…
Nutritional importance of phytate Phosphorus is an imperative nutrient for numerous biochemical pathways, physiological processes and skeletal integrity, but due to the partial availability of phytate-P, diets are supplemented with P sources such as dicalcium phosphate or, where permitted, meat-and-bone meal to meet P requirements. However, it may be argued that P requirements have been…
Cell factories Introduction Feed enzymes, like other industrial enzymes, are currently produced on a large scale mostly in submerged or deep-tank bioreactors. The production hosts are microbial, either bacterial such as Bacillus spp. (B. subtilis, B. amyloliquefaciens or B. licheniformis) or fi lamentous fungi, for example A. niger, A. oryzae, H. insolens and T. reesei….
