A Bukidnon dairy cooperative observes standing heat in a cow at 6:00 a.m. and uses conventional frozen semen. Which breeding decision best applies the principle that insemination should occur before ovulation but after sufficient sperm transport time?
- A. Inseminate late that afternoon or early evening. correct
- B. Wait until the cow refuses mounting the next day.
- C. Inseminate only after pregnancy diagnosis.
- D. Inseminate immediately at 6:00 a.m.
Why: Using the conventional AM–PM approach, a cow first observed in standing heat in the morning is commonly inseminated later the same day so viable sperm are present near ovulation.
A sow herd has a prolonged weaning-to-estrus interval after lactation. Records show excessive body-condition loss, low feed intake during hot weather, and normal boar exposure. Which intervention should be prioritized?
- A. Select only for larger mature body size.
- B. Increase lactation feed intake and reduce heat load. correct
- C. Delay weaning until all sows become obese.
- D. Remove boar contact after weaning.
Why: Negative energy balance and heat stress delay return to estrus; improving lactation nutrition and thermal comfort directly addresses the documented causes.
A goat raiser wants to increase the percentage of does kidding within a compact 30-day period without permanently changing their genetics. Which management package is most appropriate?
- A. Mate all does continuously throughout the year.
- B. Cull every doe that is not pregnant after one service.
- C. Synchronize estrus, perform heat detection, and use timed breeding or AI. correct
- D. Select only the heaviest kids at weaning.
Why: Estrus synchronization and timed breeding concentrate conceptions and kidding dates; selection changes future genetic merit but does not immediately synchronize the current herd.
A carabao cow repeatedly returns to heat 20–23 days after insemination. Semen passed quality control, but farm records show inseminations were performed before standing heat began. What is the most defensible diagnosis?
- A. The cow is genetically sterile.
- B. Embryo transfer is required.
- C. Gestation length is abnormally short.
- D. Insemination timing is likely too early. correct
Why: Regular returns to estrus indicate failure to establish pregnancy. Inseminating before true estrus can leave too few viable sperm at ovulation.
A native chicken breeding flock shows falling hatchability, while fertility remains high. Candling reveals many embryos die during the final days of incubation. Which action best targets the problem?
- A. Review incubator temperature, humidity, ventilation, and turning records. correct
- B. Select hens solely for darker plumage.
- C. Replace all roosters because fertilization failed.
- D. Increase the male-to-female ratio immediately.
Why: High fertility means eggs were fertilized; late embryonic mortality points more strongly to incubation conditions, egg handling, or breeder nutrition than to lack of mating.
A breeder identifies a boar with normal libido but one undescended testis. Semen concentration is acceptable. What is the best breeding decision?
- A. Use him heavily because one descended testis is sufficient.
- B. Exclude him from breeding because cryptorchidism may be inherited. correct
- C. Use him only for terminal-market offspring.
- D. Castrate his male offspring only after they reproduce.
Why: Even when fertility appears adequate, cryptorchidism has a hereditary component and affected males should not disseminate the defect.
A dairy goat farm wants earlier puberty without compromising lifetime productivity. Which replacement-doe policy is best?
- A. Restrict feed to prevent rapid growth.
- B. Select the earliest-cycling doe even if chronically underweight.
- C. Provide balanced nutrition and breed only when target body weight and soundness are reached. correct
- D. Breed every doe at a fixed young age regardless of body weight.
Why: Puberty and safe first breeding depend on adequate growth and body condition. Calendar age alone can expose undersized does to dystocia and poor performance.
A cow has normal estrous cycles and accepts mating, but repeated examinations show that fertilization does not occur. Which term best classifies the reproductive limitation?
- A. Fecundity
- B. Impotency
- C. Prolificacy
- D. Sterility correct
Why: Impotency is failure to copulate, whereas sterility is inability to produce normal offspring despite mating capability.
