Comportamiento productivo y rendimiento a la canal en conejos alimentados con forrajes arbóreos

Abstract

The aim of this investigation was to evaluate the effect of the ingestion of tree fodder on the productive behavior, also to the slaughter yield in rabbits. This research was executed at the Facultad de Ciencias Agropecuarias - UTA. It used 48 rabbits of 8 weeks of age, distributed at random in four experimental diets Medicago sativa (T1), Malva sylvestris (T2), Baccharis floribunda (T3), Spartium junceum (T4). It was evaluated the voluntary intake of nutrients of diets; weight gain; feed conversion; apparent digestibility of nutrients and to the slaughter yield. For the voluntary intake of organic matter T1 and T4 showed significant variance (P = 0.0001) with respect to the others treatments with values of (205.44 g and 202.92 g respectively), for the voluntary intake of raw protein the first place is for T2 (52.69) with a difference (P = 0.0001) of them others treatments, while for voluntary intake of neutral detergent fiber and voluntary intake of acid detergent fiber the treatment T1 with a difference (P = 0.0001) , was greater (81.06; 34.02). The weight gain, feed conversion and to the slaughter yield was better in treatment T2 (29.1g, 7.6 and 48.6% respectively). In them diets T1 and T2 were higher statistically (P = 0.0001) for the apparent digestibility of dry matter and apparent digestibility of matter organic with values (65.11; 67.93 and 62.72, 64.73 respectively), for the digestibility of protein raw with a significant difference (P = 0.0001) was for T1 with a value (81.77) and for ADNDF was greater in T1, followed of T2 (84.064 and 71.8). Key words: Malva sylvestris, feed conversion, weight gain, digestibility and slaughter yield
