Yucca meal: economical supplement for dairy cows
Yucca meal may be used to feed cattle without secondary digestive or milk production effects.Medellín, 18 de julio de 2014 — Agencia de Noticias UN-
They discovered that milk production and composition was similar in cows which were fed this supplement or dry food.
This research project was carried out by UNal-Medellín Zootechnician Wilyer García, whom in his master’s thesis project assessed the food supplement potential of yucca, a bioethanol byproduct, for feeding dairy cattle.
“The research project was performed in two stages. The first stage consisted of laboratory work which characterized the chemical composition of the byproduct using in vitro experiments which simulated rumen fermentation processes to assess the effects on the animal’s digestive tract,” said Garcia.
The second stage was carried out with animals in milk production phase at the UNal Paysandú Agricultural Center. There they discovered that they could replace the fifth part of the dry food with yucca meal without having negative effects on milk production or its composition.
Potentially it could be used to replace dry food making this a cheap nutritional alternative, which could be taken to a greater level when the bioethanol production industry is more developed.
The project assessed the effect of supplementing Kikuyu grass with a yucca distillate over the main rumen fermentation parameters in vitro and its impact on milk production and composition. Furthermore they analyzed dry matter forage consumption and production costs.
They discovered that main rumen fermentation parameters in vitro with 24 incubation were positively impacted by yucca distillate supplements as well as on some protozoan populations.
Finally García highlighted the importance of eventually reducing the costs of milk production systems as proved by this research project.
