Study Notes
Dairy Cattle Terminology
- A male cow is called a bull.
- Colostrum is the first milk produced after calving.
Calves Rearing
- Calves should be removed from their mother within one hour of parturition.
- Calves that don't consume colostrum can be fed using an esophageal feeder.
- The starter is a mixture of grains, protein, and molasses fed to calves after the first week.
- Water is essential for stimulating starter consumption.
Pre-Weaning Diet
- Calves should only be given water, milk, and starter before weaning.
- Hay should not be given to calves before weaning.
Heifer Management
- The objective of a heifer is to become a replacement mother in the future.
- Heifers should be bred at 15 months of age.
- Heifers calving at younger ages are not less productive than those calving at older ages.
- Heifers require a high protein and energy diet after weaning, with 50% concentrate and 50% roughages, for 2-3 months.
Milking and Lactation
- Milking should stop 60 days before parturition.
- A cow is considered "close up" when there are 21 days left until calving.
- NEI stands for Net Energy Lactation.
- Negative energy balance occurs when a cow's body weight decreases due to high milk production.
- This decrease in body weight is because the energy required to produce milk is higher than the energy consumed from the diet.
Dry Cows and Fresh Cows
- Dry cows are those in the 7th month of pregnancy.
- Fresh cows are those in the first 21 days of lactation.
Health and Nutrition
- Consuming large amounts of fat without fully metabolizing it can cause ketosis.
- The lactation period for a cow is 305 days.
- During the peak of milk production, body weight decreases due to high energy demand.
