Susticion parcial del alimento concentrado por forraje verde hidropónico de maíz (Zea Maíz), de conejos en la fase de engorde.

Abstract

The present investigation was carried out in the Santa Cecilia farmhouse El Mejoral, via San Faustino. With the objective of evaluating the effects of the partial and progressive substitution of commercial concentrated food for hydroponic green corn fodder (zea corn), on the productive parameters of rabbits in the fattening phase. Twenty animals of the New Zealand breed were used, after weaning and with an average weight of 500 to 600 g. The animals were distributed in a completely randomized design with four treatments. A hydroponic green forage (FVH) production system of Zea mays corn was established to combine with commercial concentrate feed. They were supplied in the diet of the animals during the fattening period in three different percentages of inclusion and the comparison was made with a control group with a base diet of commercial concentrated food for a period of 90 days. Data collection was carried out every 15 days, taking weight in grams, until the fattening and slaughter period ended in week 12 of the study. Once the application of the different tests had been completed and all the corresponding data had been taken, the analysis was carried out using the PROC Mixed of the SAS (9.4). The main results obtained in the present study were: total consumption (TC) of commercial concentrate feed and of for the different treatments, in addition to this, very similar values in ADG and PCF of the animals were observed in the study in relation to the control group. (P<0.01), similar results were verified in terms of efficiency in the four groups, finally the control treatment 100% concentrated food presented the highest cost in relation to cost benefit, having an investment of $8.7841 to be able to produce 1.706 kg of meat of rabbit Finally, it is concluded that the inclusion of hydroponic green corn fodder in progressive replacement of the commercial concentrate does not negatively affect the productive performance of rabbits in the fattening phase in the variables of GDP, CA, EA, in terms of carcass yield. In hot conditions, the inclusion of FVHM does not affect this indicator since final and carcass weights were obtained that were very similar to the control group without affecting quality and flavor.
