The aim of the present study was to determine phenotypic correlations between body weight of the alpaca at shearing (PCE), greasy fleece weight (PVS), clean fleece weight (PVL), performance of the fibre Andalusia wash (RFL), mean diameter of the fibre (DMF), fibre length (LF), number of loops (NR), incidence of spinal cord fibres (IM), body weight at parturition (PCP) and body weight of calf at birth (PCC). The study considered 185 white Huacaya alpacas, 1 to 7 years old, from the Lachocc Experimental Center of South American Camelids, Universidad Nacional de Huancavelica, in 2007 and 2008. The phenotypic correlations were: PVS-PVL = 0.99, PVS-LF = 0.55, PVS-DMF = 0.52, PVS-PCE = 0.41, PVL-LF = 0.57, PVL-DMF = 0.54, PVL-PCE = 0.43 (p<0.01). Fleece weight does not show any interference with main characteristics related to fibre production, and due to the high interrelation between dirt...

El presente estudio tuvo como objetivo determinar correlaciones fenotípicas entre peso corporal de la alpaca a la esquila (PCE), peso de vellón sucio (PVS), peso de vellón limpio (PVL), rendimiento de la fibra al lavado (RFL), diámetro medio de las fibras (DMF), longitud de fibra (LF), número de rizos (NR), incidencia de fibras meduladas (IM), peso corporal de la alpaca al parto (PCP) y peso de la cría al nacimiento (PCC). Se trabajó con 185 alpacas Huacaya, blancas, de 1 a 7 años de edad, del Centro Experimental de Camélidos Sudamericanos Lachocc de la Universidad Nacional de Huancavelica, durante los años 2007 y 2008. Las correlaciones fenotípicas fueron: PVS-PVL = 0.99, PVS-LF = 0.55, PVS-DMF = 0.52, PVS-PCE = 0.41, PVL-LF = 0.57, PVL-DMF = 0.54, PVL-PCE = 0.43 (p<0.01). El peso de vellón no presentó antagonismo con las principales características relacionadas a la pr...

The aim of this study was to evaluate the variation of the chemical composition and the performance of the oats-vetch, wheat-vetch and barley-vetch associations in various proportions of sowing in the form of hydroponic crops. The study was carried out in the city of Huancavelica, Peru, at 3690 meters above sea level. In total, 90 trays of 704 cm2 were used, with a density of 2.5 kg of seed/m2. Associations of oats/vetch (O/V), barley/ vetch (B/V) and wheat/vetch (W/V) with six proportions of grass/legume were used: 100/0, 80/20, 60/40, 40/60, 20/80 and 0/100. The fresh biomass production (FBP) and the chemical composition of the percentage fractions of dry matter (DM%), organic matter (OM%), neutral detergent fibre (NDF%), ethereal extract (EE%), crude protein (CP%) and total minerals (TM%) were determined. A completely randomized experimental design was used, with a factorial arrangeme...
