Dietary Anions for Milk Fever Prevention
Adding anions such as chloride (Cl–) or sulfate (SO42-) to the diet of dairy cows during the last 10–21 days of pregnancy is a highly effective prevention method for milk fever (parturient paresis). This practice induces a mild metabolic acidosis, which lowers blood pH and enhances tissue responsiveness to parathyroid hormone (PTH). Consequently, both bone resorption and intestinal absorption of calcium are increased.
Commonly used salts include CaCl2, NH4Cl,

Core Properties of Multimedia Computing
- Combination of Media: Text, audio, video, image, and animation are integrated into a single application.
- Independence of Media: Each media type in a multimedia system can exist and be processed independently. Example: Audio can be edited without changing video. Images can be compressed separately, providing flexibility in processing.
- Computer Support Integration: Multimedia systems rely heavily on computer systems for data processing, storage, compression, synchronization,
Microorganisms and Plant Biology: Essential Concepts
Understanding Viruses and Microorganisms
Viruses are not considered living things because they cannot perform nutrition or interaction. To reproduce, viruses invade an organism. The virus structure is very simple: a capsid (an external shell made of proteins that contains genetic material) and nucleic acid (genetic information).
Pathogens are microorganisms that cause infectious diseases.
A microorganism is a living thing so small that it requires a microscope to be seen. We use microorganisms to make
