Forraje verde hidropónico de maíz Zea mays y ramio Boehmeria nívea como sustituto del concentrado en dieta para conejos en fase de engorde.

Abstract

The present investigation was developed in the Villa Marina experimental farm of the University of Pamplona. The objective was to evaluate the substitution of commercial balanced feed for hydroponic green forage of Zea mays corn and Boehmeria nívea ramie in the diet on the productive performance of rabbits in the fattening phase. 12 animals of mixed breeds were used, with an initial age and average weight of two- three weeks of weaning and 1,113 kg respectively. The animals were distributed in a completely randomized design with four treatments and three repetitions. A hydroponic green forage production system (FVH) of Zea mays was established and an already established culture of Boehmeria nívea ramie was managed, these two foods were supplied in a 1: 1 ratio in the diet of the animals during the period fattening in three different inclusion percentages and a comparison was made with a commercial balanced feed base diet, this being the control diet. The data collection was carried out with a periodicity of seven days, until its fattening and slaughter period was completed in week five of the study. Once the application of the different tests had been completed and all the corresponding data had been taken, the analysis was performed using the PROC Mixed of the SAS (9.4). The main results obtained in the present study were: total consumption (TC) of similar food for the different treatments of 146.11 g, in addition to this in this study, a higher GMD and PCF of the animals of the control group (P <0.01), a higher efficiency was also verified for the animals of the control group, no effect of the treatments was evidenced on the carcass yield and the weight of the viscera of the animals. Lastly, the control treatment 100% concentrated food presented the best relationship cost benefit, having an investment of $ 6,517.2 to be able to produce 1 kg of rabbit meat. Finally, it is concluded that the inclusion of hydroponic green corn forage plus ramie in progressive substitution of the commercial concentrate negatively affects the productive performance of the rabbits in the fattening phase in the variables of GDP, CA, EA, and costs for the concept of the ration, in terms of hot channel performance, the inclusion of FVHM plus ramie does not negatively or positively affect this indicator.
