Comportamiento productivo y cuantificación de la biomasa residual disponible en un sistema cavícola.

Abstract

The project was developed at “Técnica de Ambato University” in the Agricultural Sciences Faculty (Ciencias Agropecuarias) during 75 days. In this document is described the Productive Behavior and Quantification of Available Residual Biomass in a Cavia System. The aims of the research were: rate the productive behavior and quantify the available residual biomass in guinea pigs that were fed with Italianryegrass (Lolium Multiflorum) with a balanced nutritious formulaand alfalfa or Lucerne (Medicago Sativa) with a balanced nutritious formula. Sixty guinea pigs were used as males as females, they were from 15 to 17 days old approximately, they were separated in two groups of 30 guinea pigs for each treatment. For the treatments were used two kinds of forage: Treatment 1: Italian ryegrass (Lolium Multiflorum) with a balanced nutritious formula. Treatment 2: alfalfa or Lucerne (Medicago Sativa) with a balanced nutritious formula. Each treatment was given 6 times with 5 repeated animals. The principal obtained results were the next: in animals that were fed with Lolium Multiflorum and a balanced nutritious formula ate 65.86g/MS per animal per day their weight increased 8.18g per animal per day by the other hand the other groupof animals that ate Medicago Sativa and a balanced nutritious formula ate 50.93g/MS per animal per day and won weight 7.54g per animal per day. In the nutritional conversion Lolium Multiflorum and a balanced nutritious formula obtained 8.06 while Medicago Sativa plus a balanced nutritious formula got 6.85. For the digestibility of dry material Treatment 1 got as result 62.55% while Treatment 2 got 61.-03%. For length and thorax perimeter at the end of the research Lolium Multiflorum plus a balanced nutritious formula obtained showed values of 6.43 cm and 6.2 cm per guinea pig respectively: on the other side Medicago Sativa plus a balanced nutritious formula got 6.86 cm for length and 5.73 cm pf thorax perimeter. Finally, biomass factor showed important differences obtaining as results 54.06g/MS per guinea pig per day in Treatment 1 and 48.38g/MS per guinea pig per day in Treatment 2.According to the results in Treatment 2 Medicago Sativa plus a balanced nutritious formulawould be the best food chooses for feeding Guinea Pigs.
