  • A. To reduce excessive claw growth and lameness
  • B. To increase rumen fermentation
  • C. To improve colostrum antibody levels
  • D. To increase the cow's gestation length

Explanation: Regular hoof trimming maintains normal claw shape and weight bearing, which helps reduce lameness.

Correct answer: To reduce excessive claw growth and lameness
  • A. It raises the protein content of feed
  • B. It reduces moisture and airborne respiratory hazards
  • C. It prevents cows from entering oestrus
  • D. It increases the calcium content of milk

Explanation: Good ventilation removes moisture, heat, ammonia, and contaminated air from the shed.

Correct answer: It reduces moisture and airborne respiratory hazards
  • A. The first week after weaning only
  • B. The entire period between two breeding seasons
  • C. About three weeks before to three weeks after calving
  • D. The final week of the lactation only

Explanation: The transition period generally includes the three weeks before calving and the three weeks after calving.

Correct answer: About three weeks before to three weeks after calving
  • A. Alkaline phosphatase
  • B. Urea nitrogen only
  • C. Creatine kinase
  • D. Beta-hydroxybutyrate

Explanation: Beta-hydroxybutyrate is a ketone body that rises when a cow mobilizes excessive body fat after calving.

Correct answer: Beta-hydroxybutyrate
  • A. Excess dietary protein or poor energy synchronization
  • B. Severe dietary calcium deficiency alone
  • C. Complete absence of rumen microorganisms
  • D. Insufficient access to mineral salt only

Explanation: High milk urea nitrogen commonly reflects excess rumen-degradable protein, inadequate fermentable energy, or poor synchronization between…

Correct answer: Excess dietary protein or poor energy synchronization
  • A. Uric acid
  • B. Lactic acid
  • C. Hydrochloric acid
  • D. Bile acid

Explanation: Lactic acid bacteria convert plant sugars into lactic acid, rapidly lowering silage pH and helping preserve the forage.

Correct answer: Lactic acid
  • A. Restricting feed before lambing
  • B. Washing the fleece after shearing
  • C. Increasing nutrition shortly before breeding
  • D. Giving extra salt after weaning

Explanation: Flushing means improving the plane of nutrition shortly before and during breeding.

Correct answer: Increasing nutrition shortly before breeding
  • A. Keeping animals continuously in wet muddy yards
  • B. Delaying hoof inspection until lambing
  • C. Providing only high-protein concentrate feed
  • D. Maintaining dry footing and controlling infected animals

Explanation: Foot rot spreads readily in warm, wet, contaminated conditions, so dry footing, regular inspection, treatment, and control of infected…

Correct answer: Maintaining dry footing and controlling infected animals
  • A. Calcium
  • B. Iron
  • C. Iodine
  • D. Sulfur

Explanation: Milk fever, or parturient paresis, results mainly from hypocalcaemia when calcium demand for colostrum and milk rises sharply after…

Correct answer: Calcium
  • A. Jersey
  • B. Holstein Friesian
  • C. Ayrshire
  • D. Guernsey

Explanation: Holstein Friesian cattle generally produce more milk by volume than other major dairy breeds.

Correct answer: Holstein Friesian
  • A. To stimulate appetite
  • B. To increase milk fat
  • C. To destroy organisms on the teat skin
  • D. To reduce rumen acidity

Explanation: Post milking teat dipping reduces bacterial contamination of the teat canal while it is still open.

Correct answer: To destroy organisms on the teat skin
  • A. Grass tetany
  • B. Simple indigestion
  • C. Ketosis
  • D. Ruminal acidosis

Explanation: Rapid starch fermentation produces acids faster than the rumen can neutralize them, causing ruminal acidosis.

Correct answer: Ruminal acidosis
  • A. Milking cows in a fixed sequence
  • B. Changing milking times daily
  • C. Skipping low yielding cows
  • D. Milking before udder preparation

Explanation: A fixed milking sequence supports consistent udder preparation and reduces unnecessary disturbance in the herd.

Correct answer: Milking cows in a fixed sequence
  • A. Increasing milk protein
  • B. Preventing infectious hoof disease
  • C. Improving feed intake
  • D. Treating uterine infection

Explanation: Footbaths help reduce infectious organisms on the hoof and lower the risk of conditions such as digital dermatitis.

Correct answer: Preventing infectious hoof disease
  • A. Body length per kilogram of feed
  • B. Milk colour per milking
  • C. Milk produced per unit of dry matter intake
  • D. Number of calves per lactation

Explanation: Feed efficiency is commonly assessed by relating milk output, often energy corrected milk, to dry matter intake.

Correct answer: Milk produced per unit of dry matter intake
  • A. To keep all cows at one body weight
  • B. To eliminate the need for records
  • C. To prevent all infectious diseases
  • D. To provide diets suited to nutrient needs

Explanation: Early lactation, late lactation, dry cows, and heifers have different nutrient and management requirements.

Correct answer: To provide diets suited to nutrient needs
  • A. To place sperm near the uterine horns
  • B. To avoid contact with the rumen
  • C. To increase ovarian size
  • D. To prevent milk letdown

Explanation: Deposition in the uterine body places sperm beyond the cervix and near the reproductive tract where they can move toward the oviduct.

Correct answer: To place sperm near the uterine horns
  • A. Higher wall temperature
  • B. Adequate feeding space per cow
  • C. Darker interior lighting
  • D. Reduced water access

Explanation: Providing adequate feeding space allows more cows to eat at the same time and reduces displacement of subordinate animals.

Correct answer: Adequate feeding space per cow
  • A. To prevent all reproductive disorders
  • B. To increase the salt content of milk
  • C. To support resting and normal locomotion
  • D. To replace hoof examination

Explanation: Comfortable lying areas encourage adequate rest, which supports welfare, circulation, and normal production.

Correct answer: To support resting and normal locomotion
  • A. Increased lactose synthesis by the udder
  • B. Excessive fat mobilisation after calving
  • C. Improved bacterial quality of the milk
  • D. Subclinical inflammation of the udder

Explanation: A high somatic cell count usually reflects inflammation of mammary tissue, often due to mastitis.

Correct answer: Subclinical inflammation of the udder
