Efecto de la alimentación con desperdicios orgánicos sobre la producción y reproducción de vacas lecheras.

Abstract: Para analizar el efecto de alimentos no convencionales sobre el costo de producción de la leche y las variables productivasreproductivas, 32 vacas Holstein fueron seleccionadas por número de parto y condición corporal. Se evaluaron dos sistemas de alimentación: el primero incluyó desperdicios orgá- nicos, alimento balanceado comercial y forraje (ANC), y en el segundo se utilizó alimento balanceado comercial y forraje (AC). Se encontró que el tipo de alimentación no influyó en la producción láctea ni en el inte… Show more

“…The elaboration of balanced foods in the production of animals requires ingredients that cover their biochemical and energy needs; the most used raw material for energy-protein intake is corn and soybean meal; however, in our days, this can be a limitation, due to the costs generated by its use in the preparation of food (Al-Tulaihan et al, 2004); for this reason, non-traditional alternatives have been sought, which provide lower cost and greater flexibility in the formulation; among which we can mention energy raw materials, which at least partially replace cereals, since currently the demand for cereals for human and animal consumption has increased; reflected in an increase in the production costs of feed, (Catalá-Gregori et al, 2011). Some researchers have been inclined towards these alternatives for the fattening of animals, as they are the waste of bakery in substitution of corn or sorghum in the fattening of pigs (Cárdenas, 2012), organic waste in the production and reproduction of dairy cows (Losada-Custardoy et al, 2016) and cookie flour to feed broilers (Catalá-Gregori et al, 2011). Biscuit flour is a by-product of the food industry, from the recycling of products for human consumption, which is increasingly used in the food industry of animals; its base component is wheat flour and can be considered a source of energy, given its high content of digestible carbohydrates and higher fat content than cereals; however, its composition and nutritional value may vary among suppliers (Waldroup et al, 1982), depending mainly on the quality of the initial product and processing conditions (Catalá-Gregori et al, 2011).…”
