Early lactation is one of the most demanding periods in a dairy cow’s production cycle. Energy intake is critical to support body condition, fertility, milk yield and metabolic health. One of the often overlooked tools to help optimise energy intake is granulated sugar, which can play a key role in improving rumen efficiency and mitigating metabolic challenges like ketosis.
In this article, we’ll explain why sugar is important, how it works in the diet and how Specialist Nutrition’s Gran Sugar helps farmers deliver controlled energy to their herd.
Why Energy Management Matters in Early Lactation
High producing cows often experience a negative energy balance (NEB) immediately post-calving, which can affect:
- Body condition and fertility
- Glucose synthesis, increasing the risk of ketosis
- Feed intake and rumen efficiency
Optimising energy intake during this period can lead to healthier cows, improved milk yield and solids, plus more efficient nutrient utilisation.
The Role of Granulated Sugar in Dairy Diets
Sugar can be limiting in high-producing diets, especially when sugar levels are only 5–7%. Incorporating granulated sugar offers multiple benefits:
1. Body Condition and Fertility
- Supports efficient rumen microflora
- Provides glucose precursors to help manage NEB and reduce ketosis risk
- Maintains energy supply to support reproductive performance
2. Metabolic Health
- Fast-release sugar improves glucose synthesis
- Helps stabilise energy supply post-calving
- Reduces the risk and severity of metabolic disorders like ketosis
3. Feed Intake and Efficiency
- Improves intake and palatability – encourages cows to eat more of the total diet
- Energy dense – supports high-yielding cows in early lactation
- Supports fibre digestion and passage rate – maintains rumen function and nutrient absorption
Why Choose Specialist Nutrition Gran Sugar
Ease of Handling, Storage, and Feeding
- Mixes evenly in total rations
- Low labour input
- Long shelf life
Controlled Delivery
- Rapid energy release to complement starch and protein
- Consistent solubility and release rate
- Homogenous concentration for precise diet formulation
Optimised Nutritional Balance
- Requires less crude protein balancing
- Provides flexibility to space sugar in the ration
- Helps achieve energy targets without overfeeding protein
End Result: Healthier, more efficient cows with improved milk production and solids.
Linking Energy and Ketosis Management
Adding granulated sugar is an effective strategy to stack energy in the diet post-calving, helping to:
- Encourage intake in early lactation
- Reduce the incidence of ketosis
- Support overall cow health and productivity
This can be paired with other energy-supporting feeds and strategies to maximise cow performance throughout the early lactation period.

FAQ
Q: Can granulated sugar be mixed with milk replacers or other feed?
A: Yes, it mixes evenly in total rations or electrolyte solutions.
Q: Does adding sugar require adjustments to protein or other nutrients?
A: Sugar can reduce the need for extra crude protein, allowing a more balanced and efficient ration.
Q: How does sugar improve cow health post-calving?
A: By providing fast-release energy, sugar supports glucose synthesis, helps prevent ketosis and promotes feed intake.
Q: Is sugar effective for all breeds and production systems?
A: Yes, sugar can be incorporated into dairy rations across breeds, production levels and feeding systems, with guidance from a nutritionist.
