digestibility trial: A test to measure the digestibility of a known food by recording the weight of food eaten and then excreted. Conducting digestibility trials is important for evaluating the nutritional value of animal diets. Farmers should work with veterinarians and nutritionists to perform digestibility trials and develop balanced and nutritious diets for their livestock. Understanding the results of digestibility trials will aid in effective feed management and improved farm productivity.

digestive enzymes: Enzymes which speed up the process of digestion. Providing digestive enzymes can improve the efficiency of nutrient absorption in livestock. Farmers should work with veterinarians and nutritionists to include digestive enzymes in animal diets as needed. Understanding the benefits and applications of digestive enzymes will aid in effective feed management and improved farm productivity.

digestible: Able to be digested. Glucose is an easily digestible form of sugar. Providing digestible nutrients is essential for maintaining the health and productivity of livestock. Farmers should work with veterinarians and nutritionists to ensure that animal diets are highly digestible and promote optimal health. Understanding the importance of digestible nutrients will aid in effective feed management and improved farm productivity.

dam: The mother of an animal. Knowing the lineage and health of the dam is important for breeding programs and offspring quality.

drill coulter: A coulter that makes a furrow for sowing seed. Drill coulters are essential for precision planting, helping to create uniform seed rows and improve crop establishment.

disinfectant: A substance which removes harmful organisms such as bacteria, viruses, or fungi from a place or an object by cleaning it. Proper use of disinfectants is essential for maintaining farm hygiene and preventing disease outbreaks. Farmers should select the appropriate disinfectant for their needs and use it according to label instructions. Understanding the benefits and applications of disinfectants will aid in effective disease management and improved farm productivity.

draft off: To remove certain animals from a herd or flock. Drafting off animals is a common practice in livestock management to separate animals for breeding, health reasons, or sale.

dray: A flat cart without sides. Drays are used for transporting heavy loads on farms, such as hay bales or equipment.

Dutch barn: A type of farmyard building used for storage of hay, loose or baled, corn crops, and agricultural implements. The older types of Dutch barn were built of iron with no enclosing side walls. Modern designs incorporate precast concrete, asbestos-cement sheeting with curved roofs. The sides may be partly or completely covered. Dutch barns provide essential storage for farm products and equipment, protecting them from the elements.

deficiency payment: Payment made to a producer when the price for a commodity at the market does not reach a preset guaranteed price. Deficiency payments can provide financial stability for farmers during periods of low market prices. Farmers should stay informed about eligibility requirements and application processes for deficiency payments to take advantage of this support. Understanding market trends and diversifying income sources can also help mitigate the impact of low prices.
