1. Species of forage: Different species of forages have varying levels of nutrients and digestibility. Some species, such as alfalfa, have higher protein content and digestibility compared to others.
2. Maturity: The stage of maturity at which the forage is harvested can greatly impact its nutritive value. Forages harvested at an early stage of growth tend to have higher protein content and digestibility, while forages harvested at a later stage may have lower protein content and higher fiber content.
3. Soil fertility: The nutrient content of forages is influenced by the fertility of the soil in which they are grown. Forages grown in nutrient-rich soils are likely to have higher levels of nutrients compared to those grown in nutrient-poor soils.
4. Climate and weather conditions: Weather conditions, such as temperature, rainfall, and sunlight, can affect the growth and nutrient content of forages. For example, drought conditions can reduce the nutrient content of forages, while optimal growing conditions can enhance nutrient levels.
5. Harvesting and storage methods: The way in which forages are harvested and stored can impact their nutritive value. Proper harvesting techniques, such as cutting at the right stage of maturity and minimizing leaf loss, can help preserve the nutrient content of forages. Additionally, proper storage methods, such as ensiling or drying, can help maintain the quality of forages over time.
6. Processing: Some forages may undergo processing, such as grinding or pelleting, which can affect their digestibility and nutrient availability. Processing can help break down cell walls and increase the accessibility of nutrients to animals.
7. Presence of anti-nutritional factors: Some forages may contain anti-nutritional factors, such as tannins or oxalates, which can reduce the digestibility and availability of nutrients. Proper processing or treatment methods may be needed to reduce the impact of these factors on the nutritive value of forages.
2. Maturity: The stage of maturity at which the forage is harvested can greatly impact its nutritive value. Forages harvested at an early stage of growth tend to have higher protein content and digestibility, while forages harvested at a later stage may have lower protein content and higher fiber content.

Plant Factors:
- Species and Cultivar: Different forage species and cultivars have varying nutrient compositions. Legumes (e.g., alfalfa, clover) are typically high in protein, while grasses (e.g., timothy, fescue) are lower.
- Maturity Stage: Forages harvested at a younger stage tend to have higher nutritional value, as they contain more soluble carbohydrates and proteins, and less fiber.
- Environmental Conditions: Factors such as sunlight, temperature, water availability, and soil fertility can affect the nutrient content of forages.
Harvesting and Storage:
- Harvesting Time: Harvesting at the optimal time ensures maximum nutrient content. Cutting too early reduces yield, while cutting too late results in lower quality.
- Harvesting Method: Mechanical harvesting can damage leaves and reduce nutrient retention. Windrowing and baling can also lead to nutrient losses.
- Storage Conditions: Forages must be stored properly to prevent spoilage and nutrient degradation. Factors such as moisture content, temperature, and oxygen levels can affect storage quality.
Other Factors:
- Management Practices: Proper fertilization, grazing, and irrigation practices can improve forage quality.
- Animal Species: Different animal species have different nutrient requirements, which can influence the selection and management of forages.
- Supplementation: Additional nutrients may be needed to supplement forages, especially for high-producing animals.
Specific Nutrients Affected:
- Protein: Species, maturity stage, and harvesting method affect protein content.
- Energy: Soluble carbohydrates and fiber content influence energy value.
- Minerals: Soil fertility and fertilizer application affect mineral levels.
- Vitamins: Sunlight exposure and storage conditions can influence vitamin content.
