Feed microscopy is a flexible, fast and inexpensive feed quality control technique. It is the ideal complement for the classical chemical analyses (Weende, van Soest,), and provides faster general information on ingredient quality. It is especially useful for the identification of tainting or adulterating materials, or for quantitative determinations when specific physical or chemical methods…
Definition The feed adulteration is defined as an advertent, deliberate and illegal alteration of a pure feed raw material by adding any other ingredient and its sale by declaring it as a pure feedstuff. Some feed Feed Adulterants FEED INGREDIENTS ADULTERANTS EXAMPLES OF ADULTERATION The contaminations due to management or poor practices include:

Biogeochemical cycles are the pathways through which essential elements and compounds such as carbon, nitrogen, phosphorus, sulfur, and water move through the Earth’s various systems, including the atmosphere, hydrosphere, lithosphere, and biosphere. These cycles play a critical role in regulating the availability of nutrients and sustaining life on Earth. Here’s an overview of some key…
Earth can be visualized as a giant system composed of four major interconnected spheres: The terms atmosphere, hydrosphere, lithosphere, and biosphere represent the major earth systems or spheres that together constitute the earth’s environment and support life. Here’s an overview of each of these spheres: Atmosphere: The atmosphere is the gaseous envelope surrounding the Earth….
Ecosystems are complex and dynamic communities of living organisms (biotic components) interacting with their non-living physical and chemical environment (abiotic components). The concept of interaction and homeostasis within ecosystems plays a crucial role in maintaining balance and stability. Here’s an explanation of these concepts with an emphasis on their significance: Producers (autotrophs): Capture energy from…
During hot weather and periods of stress, such as heat stress in poultry, adjustments to nutrient levels and management practices are crucial to maintain bird health, welfare, and performance. Here are some key nutrient adjustments and management strategies to consider during hot weather and stress in poultry: 1. Water: Availability: Ensure continuous access to clean,…
Feed additives are substances added to poultry diets in small quantities to improve feed quality, enhance nutrient utilization, promote growth, and maintain bird health. These additives serve various purposes and can include nutritional supplements, antimicrobials, enzymes, antioxidants, and more. Here are some common types of feed additives used in poultry diets: 1. Nutritional Supplements: Vitamins:…
Nutritional diseases caused by deficiencies in vitamins and minerals can have significant impacts on the health, growth, and productivity of poultry. Here are some common nutritional diseases in poultry resulting from deficiencies in vitamins and minerals: 1. Vitamin A Deficiency: Disease: Vitamin A deficiency can lead to various problems, including poor growth, skeletal abnormalities, reduced…
