Understand precise animal nutrition
The dairy sector faces the dual challenge of increasing milk production to meet society’s demands while minimizing environmental impact. Precision animal nutrition is emerging as an important strategy in addressing these challenges. Precision animal nutrition involves providing livestock with exactly the nutrients they need and avoiding excess. Over the past two decades, there has been a major shift toward reducing nitrogen (N) and phosphorus (P) content in animal diets. Notably, the New York herd reduced dietary nitrogen by 10.8 percent from 1999 to 2019. At the same time, milk production per cow jumped by 40 percent, and total nitrogen excretion in manure decreased by 8.1 percent.
Benefits to animal health and welfare
Precise feeding and nutritional management greatly improves animal health and welfare in the dairy industry by providing diets tailored to the specific needs of individual cows or herds. This approach utilizes advanced technology and detailed monitoring to ensure each animal receives the optimal combination of nutrients it needs for its health and productivity. One of the main benefits of precision feeding is increased nutrient efficiency and reduced waste and environmental impact. Technologies related to precision feeding also enable continuous monitoring of health indicators such as body weight, milk composition, and feeding behavior. This real-time data collection supports proactive health management and allows for immediate dietary adjustments.
Reducing methane emissions
Methane emissions from livestock, especially ruminants such as cows and buffalo, are a major contributor to greenhouse gases. Precision animal nutrition offers a promising solution to reduce these emissions. Fine-tuning livestock diets based on their specific digestive and metabolic needs can reduce methane production during digestion. For example, the introduction of certain fats and oils can partially inhibit the methane production process in the rumen, reducing methane emissions by up to 6%. Additionally, food additives like nitrates and certain plant extracts have been shown to reduce methane emissions by altering the fermentation process in the stomach.
Precision animal nutrition also plays an important role in managing toxins in livestock diets. This approach to accurately formulating feed and monitoring nutrient intake ensures that animals are not exposed to harmful levels of natural feed toxins, such as mycotoxins. Mycotoxins can affect animal health and productivity. Advanced feed technology can detect and control the presence of these toxins, ensuring feed is safe and beneficial.
The role of technology
Technology plays a vital role in precision feeding, optimizing nutrition and feeding methods on dairy farms, improving animal health and productivity. Some notable technologies include:
1. Milk yield and electrical conductivity: This technology focuses on maintaining milk yield and composition consistency. It identifies nutritional and metabolic imbalances, but can miss subtle changes that indicate health problems.
2. walking activities: Studies have shown that dairy cows with higher levels of non-esterified fatty acids (NEFA) tend to be less active. This decrease in activity is negatively correlated with increased plasma NEFA levels in postpartum cows, indicating a potential health concern.
3. Feeding behavior and intake: Changes in dry food intake and behavior before calving may indicate a difficult delivery. Cows with dystocia often eat less and exhibit behavioral changes up to two weeks before calving, which can help identify cows at risk for diseases such as fatty liver and ketosis.
Four. milk fat percentage: Online monitoring of milk fat levels allows diagnosis of rumen acidosis, which is influenced by feed composition and the presence of unsaturated fatty acids in the feed.
Five. Body condition score (BCS): BCS is essential for long-term energy balance management, slowly reflects changes in body fat stores, and is associated with milk production, reproduction, and overall health.
6. Rumen pH: Monitoring rumen pH can help manage subclinical ruminal acidosis (SARA), a common metabolic problem. This parameter is very important for leading to optimal rumen fermentation, thereby influencing the production and health of individual cows in different ways.
Collectively, these technologies can help fine-tune feeding strategies, detect early signs of health problems, and enhance overall dairy management.

conclusion
In conclusion, precision animal nutrition offers an innovative approach to animal husbandry that benefits animal health, the environment, and farmers’ economic interests. As this technology evolves and becomes more accessible, it has the potential to become a standard practice in sustainable agriculture, leading to a more efficient and responsible agricultural future.
