Assignments
- Embryo transfer: Explain the concept of embryo transfer, including superovulation of donor cows, collection of embryos, and their transfer to recipient cows. Discuss the benefits and challenges of this technology.
- In vitro fertilization (IVF): Describe the IVF process, from oocyte (egg) collection and fertilization in a laboratory setting to embryo culture and transfer. Discuss how IVF can accelerate genetic progress.
- Cloning: Explain the principles of cloning in cattle, including somatic cell nuclear transfer. Discuss the ethical considerations surrounding cloning and its potential applications.
- Sexed semen: Describe the technology of sex-sorted semen, which allows for the selection of the desired sex of offspring. Discuss the applications and potential limitations of sexed semen.
- Importance of AI: Discuss the reasons why artificial insemination is used in dairy cattle breeding, including genetic improvement, disease control, and cost-effectiveness.
- Preparation: Outline the necessary preparations before AI, such as estrus detection, synchronization of estrus, and selection of quality semen.
- Insemination procedure: Describe the AI procedure, including handling and thawing of frozen semen, proper placement of the insemination gun, and techniques for depositing semen into the reproductive tract.
- Timing and monitoring: Explain the importance of accurate timing in AI and how veterinarians or technicians monitor the cow's reproductive status.
- Pregnancy diagnosis: Discuss methods for pregnancy diagnosis after AI, such as rectal palpation or ultrasound, and the timing of these diagnostics.
- Advantages and challenges: Analyze the advantages of AI over natural mating, as well as potential challenges and limitations.
1. Research the process of milk synthesis within the mammary glands. Explain the roles of various cell types involved, such as alveolar cells and myoepithelial cells.
2. Detail the stages of lactation and how the composition of milk changes throughout the lactation cycle.
3. Discuss the nutritional components of milk, including proteins, fats, carbohydrates, vitamins, and minerals.
