Animals/Poultry Nutrition
Dry Matter Determination
1. Principle Dry matter is determined gravimetrically as the residue remaining after drying at 103 ÂșC in a ventilated oven. 2. Scope This procedure is applicable for determination of dry matter in feed ingredients, feeds and partially-dried (85% dry matter) forages with low volatile acid content. For whole grain, silage and high sugar feeds, use…
DIGESTION AND ABSORPTION OF NUTRIENTS
The digestion, metabolism, and absorption of nutrients in broilers (young chickens raised for meat production) are complex processes essential for growth, development, and overall health. Here’s an overview of how these processes occur in broilers: 1. Digestion: Mouth: The digestion process begins with mechanical breakdown as broilers peck, tear, and grind feed particles. Salivary enzymes…

Sources and classification of nutrients and their functions
Sources and classification of nutrients and their functions Nutrients are substances that the body needs to function properly. They can be classified into several categories based on their chemical structure and functions. Here are the main categories of nutrients, along with their sources and functions: 1. Macronutrients: Carbohydrates: Sources: Grains, fruits, vegetables, legumes. Functions: Primary…
PHYSICAL EVALUATION OF FEED STUFF AND IDENTIFICATION OF MATERIAL
Introduction: The physical evaluation of feed mostly provides preliminary information on the quality of the material. It involves assessing physical qualities such as weight, colour, smell and whether the material has suffered from any contamination by other materials. Importance of Feed Evaluation Feed evaluation is important because ingredients that belong to the same class contain…
Anti-nutritional factors in feed stuffs for ruminants
Anti-nutritional factors Anti-nutritional factors (ANFs) are substances that when present in animal feed or water they either by themselves or through their metabolic products reduce the availability of one or more nutrients. Plants contain starch polysaccharides and no-starch polysaccharides (NSPs), and some of them are anti-nutritional factors. NSPs contain sugars other than glucose and/or have…
Poultry Nutrition
Poultry nutrition has been extensively researched so the nutritive requirement of laying hens is well known. The degree of sophistication is such that different strains of laying hens have feeds formulated to meet their specific requirements. The basic requirements are for protein, carbohydrates, fats, vitamins, and minerals. The protein requirement is met by including soybean meal, corn gluten meal, meat and bone…
