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 effect of E. coli and Salmonella spp on the growth and mortality of baby alpacas (Vicugna pacos). It was selected 104 Huacaya alpacas with diarrheal processes and with an average age of 10.0 ± 2 days, body weight of 9.6 ± 0.5 kg and height at the withers of 85.0 ± 0.5 cm. Samples of rectal swabs were cultured in selective culture media of MacConkey, EMB, SS, XHD and BIH agar, and biochemical tests were performed. Based on the positive results of E. coli and Salmonella spp. A total of 80 animals were selected and assigned into four groups: G1, E. coli (n=23); G2, Salmonella spp (n=17); G3, E. coli – Salmonella spp (n=12); G4, control (n=28), positive for one or both germs and treated with tetracycline. The animals were weighed and measured (height at the withers) at weeks 4 and 8 of the study and mortality was recorded. The weight and corpora...
