Study Notes
Digestion
- Mastication is the mechanical breakdown of food into smaller particles
- Salivary amylase converts starch to maltose
- Tongue grasps and manipulates food
- Prehension is the act of seizing food
- Salivary glands produce saliva with mucin to lubricate food
- Small intestine is the primary site of nutrient absorption
- Digestion involves mechanical forces, chemical action, and enzyme activity
- Digestive enzymes are complex proteins that catalyze digestion
- Chemical changes in nutrients occur throughout the digestive process
Reproduction
- Ampulla produces sperm and androgens, located in the scrotum
- Seminal vesicles secrete fructose for sperm transport
- Testes function optimally a few degrees cooler than body temperature in the scrotum
- Epididymis is the site of sperm maturation
- Prostate gland surrounds the urethra and produces a secretion that stimulates sperm activity
Poultry
- Feed wastage is 30% when the trough is completely full
- Complete confinement housing requires less space
- Colt is a young male horse up to 3 years old
