In MOET, the animal is either mated with an elite bull or artificially inseminated. The fertilized eggs are collected to transfer to surrogate mothers.
Which among these statements is correct .

Options

A. Fertilized egg is collected at 8-32 cells stage and no need of surgery.
B. Fertilized egg is collected at 8-32 cells stage and surgery is done for it.
C. Fertilized egg is collected at only 4 cells stage and it is done by surgery.
D. Fertilized egg is collected at 64 cells stage and surgery is done for it.

Answer

To solve the question regarding MOET (Multiple Ovulation Embryo Transfer Technology), let's break down the process step by step:

### Step-by-Step Solution:

1. **Understanding MOET**:
- MOET stands for Multiple Ovulation Embryo Transfer Technology. It is a reproductive technology used in livestock to enhance the number of offspring produced from a female animal.

**Hint**: Remember that MOET is aimed at increasing the number of hybrids in a herd.

2. **Hormonal Treatment**:
- In MOET, the female animal (usually a cow) is treated with hormones that have FSH-like activity. This treatment stimulates the maturation of multiple follicles, leading to superovulation.

**Hint**: Focus on the role of hormones in stimulating follicular development.

3. **Egg Production**:
- Due to the hormonal treatment, the cow can produce 6-8 eggs per cycle instead of the usual one egg. This is a significant increase that allows for more embryos to be created.

**Hint**: Consider how the number of eggs produced impacts the overall goal of MOET.

4. **Fertilization**:
- The cow is then either mated with an elite bull or artificially inseminated to fertilize these eggs.

**Hint**: Think about the methods of fertilization used in this technology.

5. **Embryo Collection**:
- The fertilized eggs (embryos) are collected at the 8 to 32 cell stage. This stage is crucial as it ensures that the embryos are viable for transfer.

**Hint**: Identify the specific stage at which embryos are collected.

6. **Transfer to Surrogate Mothers**:
- The collected embryos are then non-surgically transferred to surrogate mothers, where they will develop until birth.

**Hint**: Note the method of transferring embryos and its significance.

7. **Evaluating the Statements**:
- Now, we need to evaluate the statements provided in the question:
- **Statement 1**: "Fertilized egg is collected at 8 to 32 cell stage and no need of surgery." - This is correct.
- **Statement 2**: "Fertilized egg is collected at 8 to 32 cell stage and surgery is done for it." - This is incorrect.
- **Statement 3**: "Fertilized egg is collected at only 4 cell stage." - This is incorrect.
- **Statement 4**: "Fertilized egg is collected at 64 cell stage." - This is also incorrect.

**Hint**: Compare each statement against the information provided about MOET.

### Conclusion:
The correct statement is that the fertilized egg is collected at the 8 to 32 cell stage and no surgery is needed for this process. Therefore, the answer is **Statement 1**.
