Animal/Poltry Nutrition

1. Principle Gross energy is measured by combustion of a sample in an excess of oxygen in a bomb calorimeter under standardized conditions. The gross calorific value is calculated from the temperature rise of the water in the calorimeter vessel

1. Principle A water extract from silage is acidified and centrifuged. The alcohols and volatile fatty acids (VFA) are separated in the chromatography column depending on their molecular weight and then detected, identified, amplified, and areas integrated. 2. Scope The

1) Apparatus:- Ultraviolet light (UV), glass plates, 4×8, spreader , oven ,micro pipette, beaker ,shaker ,electric balance, water bath, china dish 2) Reagents:- Silica gel (powder form) 254 Gr 60 number, double dish H2O, chloroform, standard solution, 3) Procedure:- Sample

1. Principle The sample (feed or feed ingredient) is suspended in distilled water with a clarifying agent. The urea content is determined using a spectrophotometer after addition of 4-dimethylaminobenzaldehyde (4-DMAB). 2. Scope The method is suitable for feeds and forages.

Nutrition plays a critical role in the health, productivity, and overall performance of ruminants. Ruminant animals, such as cattle, sheep, goats, and buffalo, have a unique digestive system that allows them to efficiently process fibrous plant material. Their nutritional needs

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
