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…
