Veterinary Medicines Regulations 2013π Withdrawal periods:
- Prevent residues entering food chain
- Rumen = fermentation vat (microbes break down fibre)
- Reticulum = traps foreign objects
- Omasum = absorbs water
- Abomasum = βtrue stomachβ (acid digestion)
- Simple stomach with acid digestion
- Limited fibre digestion β rely on concentrates
Animal Feed Regulations 2010
- Feed must be safe
- Stored correctly
- Free from contamination
1. Which part of the stomach breaks down fibre using microbes?
2. What is the function of the reticulum?
3. Why is the abomasum called the βtrue stomachβ?
4. Why can cattle eat grass but pigs cannot?
- Rumen: fermentation vat with microbes
- Reticulum: traps foreign objects (hardware disease risk)
- Omasum: absorbs water
- Abomasum: acid digestion (like human stomach)
Key takeaway: Ruminants can use grass because microbes break down fibre into usable energy.
| Animal | Cycle | Key Detail |
|---|---|---|
| Cow | 21 days | Short heat β easy to miss |

| Pig | 21 days | Long heat β easier detection |
- Standing to be mounted (most reliable sign)

| Animal | Gestation | Key Detail |
|---|---|---|
| Cow | 283 days | ~9 months |

Sheep usually have a 17-day oestrus cycle and are seasonal breeders.
This is the most reliable heat detection sign in livestock.
Pig gestation is approximately:
- 3 months
- 3 weeks
- 3 days
Cow gestation is about 9 months.
- Cow: 21-day cycle β’ 283-day gestation
- Sheep: 17-day cycle β’ seasonal breeder β’ 147-day gestation
- Pig: 21-day cycle β’ 115-day gestation
- Best heat sign: standing to be mounted
- Pig memory trick: 3 months, 3 weeks, 3 days
- Reduced intake β early illness indicator
- Lameness β pain/injury
- Isolation β stress/disease
- Discharge β infection
- Cattle β lameness common (foot issues)

1. Which of these is a clear sign of a healthy animal?
2. What is often the FIRST sign of illness?
