Preparing an inventory of fauna (animal species) in a given region is a systematic process that involves collecting data on the various species present. Here are the steps to prepare such an inventory:
The economics of poultry rations deals with the cost-effective formulation, production, and utilization of poultry feed to ensure optimal bird performance (growth, egg production, feed efficiency) and maximum profitability for producers. Since feed is the largest cost component in poultry production (typically 60–70% of total production costs), understanding its economics is critical for sustainable poultry…
Local species extinction, referring to the disappearance of a species from a specific geographic area, can be attributed to various factors. Here are some common causes of local species extinction: A field excursion focused on biodiversity is a valuable opportunity to explore and study the variety of species and ecosystems in their natural habitats. Here’s…
Poultry, like all animals, require a balanced diet that meets their physiological needs for growth, reproduction, maintenance, and production (meat or eggs). The essential nutrients include water, energy (carbohydrates and fats), proteins (amino acids), vitamins, minerals, and enzymes. The optimum levels vary based on species (broiler, layer, breeder), age, production stage, and environmental conditions. 1….
1. Feed Additives Feed additives are substances added to poultry feed to improve its quality, enhance performance, prevent diseases, and improve the efficiency of feed utilization. They include nutritional additives (like vitamins and amino acids) and non-nutritional additives (like antibiotics, enzymes, and antioxidants). 2. Antibiotics Antibiotics are used in poultry to: Concerns: 3. Coccidiostats Coccidiostats…
Introduction Global warming refers to the long-term rise in the Earth’s average surface temperature due to human activities, primarily the emission of greenhouse gases. It is one of the most pressing environmental issues facing the world today, with widespread consequences including extreme weather events, rising sea levels, melting glaciers, and loss of biodiversity. Major Contributors…
1. Introduction Nutritional and metabolic disorders in ruminants occur when the balance of nutrients, energy, or metabolic processes is disrupted due to poor feeding practices, imbalanced rations, or physiological stresses (e.g., calving, peak lactation). These disorders not only reduce productivity (milk, meat, reproduction) but also lead to health complications and economic losses. 2. Common Nutritional…
1. Introduction Feed additives are non-nutritive substances added to ruminant diets in small quantities to improve growth performance, feed efficiency, health, and productivity. These compounds are not required for basic nutrition but modulate digestion, metabolism, immunity, or microbial activity to achieve specific production goals. With increasing demand for efficient, safe, and sustainable livestock production, feed…
