Critical On-Farm Analyses
Philosophically, human brain work for quality life evolves based on insightful experience . Beet pulp, as a by-product of sugar production, is a relatively energizing feed ingredient that is especially rich in plant cell wall and pectin. Pectin, although a fibrous component, is not pragmatically considered an effective fibre since it is easily and rapidly fermented by rumen microbes. Thus, in terms of extent and rate of fermentation, pectin is usually and generally named alongside starch in modern ruminant nutrition and management [2-4]. High rate of beet pulp fermentation has in ways confused dairy managers in categorizing it as either a concentrate or forage item. In other words, beet pulp is a source of both energy and fiber.
Historically, beet pulp popularity goes back to traditional smallscale farming where and when concentrate items were not as diverse and available as they now are. In such scenarios, farmers were eager to feed soaked beet pulp mixed with straw and bran to increase milk production. However, farmers have always raised a question about lowered milk fat content when feeding beet pulp.
In the current ruminant feed market in Iran, beet pulp is even more expensive than corn and barley grains. Its commercial price is almost comparable to the invaluable alfalfa. These mean that per unit of effective fiber and microbial mass-yielding available starch, beet pulp is far more costly than main dietary forage and concentrates, thus questioning its use in fresh and high-producing cow diets where space is a real challenge.
It is contemplated that devoting a considerable space of 5-10% (DM basis) to beet pulp in early lactation dairy diets may not be greatly justifiable where safer ingredients can be included towards healthier rumen conditions and higher quality milk production. Early postpartum and peak lactation are times when rapidly improved nutrient intake and low-risk rumen conditions are highly demanded [5-7]. National and international farm experience suggests that dietary inclusion of beet pulp has rather become a sightless habit than coming from a practical wisdom. Such a malpractice must indeed be reevaluated for correction and clarification.
Reviewing the traditional basis of beet pulp feeding in dairy farming, it must be noted that the popularity of beet pulp in the past was reasonably due to a broad hesitation in feeding much cereal starch. Risks from various forms of rumen acidosis and decreased milk fat and solids production and cow health were an impetus to feed an apparently safer feed (beet pulp) that would provide both energy and cell wall fiber simultaneously without possibly jeopardizing rumen fermentation and health. Now, the situation is entirely different. Starchy grains are principally and considerably used in commercial dairy rations. This necessitates greater needs for physically and chemically effective cell wall fibers to maintain reasonable rumen health and cow longevity [7,8]. The future use of beet pulp in dairy rations, especially for fresh and early lactation cows, requires a multitude of serious physiological and economical considerations towards sustainable food safety and security.
Concerns were raised against careless inclusion of beet pulp in commercial dairy rations, particularly for fresh and early lactation cows encountering major challenges in rumen and intermediary metabolism. Costliness, lack of adequately effective cell wall fiber, very high rumen degradability, and milk fat-lowering nature are amongst the critical factors cautioning measurable beet pulp feeding in postmodern dairy production.
