TOLA-PAZ, Ariel Gonzalo et al. Determinación del incremento de peso posdesteté con bloques multinutricionales y ensilaje de cebada en Llamas (Lama glama, Linnaeus 1758) en el Centro Experimental Agropecuario CondoririDetermination of weight gain after weaning with multinutrient blocks and barley silage Llamas (Lama glama, Linnaeus 1758) in the Condoriri Agricultural Experimental Center. J.Selva Andina Anim. Sci. [online]. 2015, vol.2, n.1, pp.13-21. ISSN 2311-3766.

It increased weaning weight BMN, ESC and traditional grazing in flames in the ECAC, and BANCAMEL was evaluated. Fieldwork in weaning flames 27 ± 2 months two weeks, randomized into 3 groups of nutritional supplementation BMN, ESC and witnesses without supplementation, weighing pups were performed every 15 days were used each to 06 hours : 00a 9:00 a.m. for 105 days. Multinutrient blocks were made: barley meal 12.5% ​​alfalfa meal 12.5% ​​flour, chaff quinoa 12.5% ​​flour, chaff bean 12.5%, clay 10%, urea 5% minerals 5% molasses 30%, 65% barley silage, urea 5% 30% molasses. Block witnesses was based on grazing, typical of the area. The BMN consumed 117.33 kg, 464.1 kg and ESC only witnesses were with the traditional grazing without supplement. The average weight increase of 0.41 kg in BMN flame, called ESC 0.25 kg, witnesses a weight loss of -2.6 kg per animal was taken. Registration weighing over 105 days, a decrease in weight was observed in witness’s kg 36.389-34.772 end, this may be due to traditional grazing system without supplementation. In the BM of 38.611-42.333 kg with an average increase of 3.722 kg unlike ESC, it increased from 36.056-33.8389 Kg 2.633 Kg. Supplementation with multinutrient blocks is satisfactorily acceptable unlike the treatment with barley silage, being much better compared to the controls (without supplement no fee).
