Efecto de dos reconstituyentes comerciales en el rendimiento productivo de oveja mestizas

Abstract

In Experimental Tunshi Station of the Animal Science Faculty, ESPOCH, the productive perfomance of was crossed sheep evaluated, by the effect of the application of two commercial restorative Yodatrex and Valack-B12, they were compared with a control treatment, distributed under Completely Randomized Design , evaluating different production variables during 120 days of investigation. The animals were fed: TO; grazing forage mixture (Lolium perenne and Medicago sativa): T1; corn silage + concentrate and Yodatrex application, 2ml / 50Kg p.v. in periods of 30 days: T2; corn silage + concentrate and Valack - B12 application, 1ml / 10Kg p.v. in periods of 30 days The nutritive quality of diets were 12% PB and EM 1.84 Mcal / Kg MS for silage and concentrates; 6.15% PB and MS. 2.4 Mcal / Kg DM. Determining the best final weight (P <0.01) 45.40 Kg in T1, and TO to 38.80 Kg. Similarly the weigth increment (P <0.01) 7.10 Kg and 1.00 Kg respectively, the body condition score (BCS) (P <0.01) 3.70 points (T1) and 2.30 points (TO), the alimentary conversion (AC) (11.82) T1; (56.5) TO. Regarding to the evaluated blood biometric evaluated in terms of blood count, the best results were obtained with the T1, for the following variables: 10,80x10 ° leucocytes Imm erythocytes (neutrophils, lymphocytes, monocytes pun eosinophils), (% platelets (9, 39x10 Imm), hemoglobin (12.0g / dl), hematocrit (32.0 (642.0x10 / mm) and blood chemistry; Ca (10.40 mg / dl), P (5.40 mg / dl) and Mg (2.30 mg / dl), the best benefit - cost, cost $, 1.06. That is why it is recommended Yodatrex as metabolic tonic in periodic applications, and disseminate the results obtained in this research at the level of large, medium and small producers of sheep in the central region.
