Forrajes verdes hidropónicos de cebada, trigo y avena forrajera enriquecidos con microorganismos benéficos para la crianza de cuyes (Cavia porcellus)

Abstract

Hydroponic green fodder represents a form of food production as a result of the germination process of cereals or legumes, which can be used in animal feed. The objective of the study was to evaluate the use of hydroponic green forages of barley, wheat, and forage oats enriched with beneficial microorganisms as an alternative in the breeding of guinea pigs (Cavia porcellus). 90 weaned guinea pigs of the Peru line, weighing 300 ± 20 g, were distributed under a complete randomized design, in three treatments, T1 (barley HGF), T2 (wheat HGF) and T3 (forage oats HGF), including 3 replicates per treatment and 10 guinea pigs per replicate. The variables to be analyzed were guinea pig production parameters, forage mass yield and in vivo digestibility of dry matter, protein, and fiber of each HGF. The results on forage mass yield recorded the highest benefit for the wheat HGF with a weight of 3,200g; the best in vivo digestibility in terms of dry matter, crude protein, and fiber was achieved by the wheat hydroponic culture with 32.11%, 19.40%, and 18.32%, respectively. The best productive parameters of guinea pigs were achieved with the consumption of wheat HGF, registering a weight of 903.77 g and feed conversion of 7.3. It is concluded that HGF can be an alternative feed in guinea pig breeding systems. Keywords: hydroponic crops, guinea pigs, productive parameters
