ScanSolve AI Answer
a) The practice illustrated is raddling or mating/service marking.
b) Three reasons for carrying out this practice are:
- To identify females that have been served by the male, allowing for accurate record-keeping of mating dates.
- To detect repeat breeders (females that return to estrus after being served), indicating a failure to conceive.
- To monitor the activity and effectiveness of the male (e.g., ram or buck) by observing how many females he has marked.
c) Three causes of infertility in farm animals are:
- Nutritional deficiencies, such as lack of essential vitamins, minerals, or energy.
- Diseases or infections of the reproductive tract, like brucellosis or vibriosis.
- Hormonal imbalances that disrupt the estrous cycle or ovulation.
