EFECTO DE LA SUPLEMENTACIÓN ALIMENTICIA CON FUENTES LIPÍDICAS SOBRE LA GANANCIA DE PESO Y NIVELES DE TESTOSTERONA SÉRICA EN TOROS BUFALINOS / EFFECT OF NUTRITIONAL SUPPLEMENTATION WITH LIPIDS ON WEIGHT GAIN AND TESTOSTERONE LEVELS OF WATER BUFFALO BULLS

Resumen


El objetivo del estudio fue evaluar el uso de concentrados a base de torta de copra y torta de palmiste en la suplementación de toros bufalinos mantenidos en pastoreo rotacional intensivo y comprobar su efecto sobre el peso corporal, el perímetro escrotal y los niveles de testosterona sérica. Quince búfalos (457,8±98,3 kg y 3,2±1,3 años) fueron tenidos en pastoreo (Panicum maximum vr. Mombaza) y recibieron suplementación diaria (1% del peso corporal) en comederos individuales. Los animales fueron asignados aleatoriamente en tres tratamientos: Control (n = 5; concentrado convencional, a base de maíz y salvado de soya), T1 (n = 5; concentrado a base de torta de copra) y T2 (n = 5; concentrado a base de torta de palmiste). El experimento duró 252 días, subdivididos en 9 periodos de 28 días (P1 a P9). El consumo de la ración fue controlado diariamente, el peso corporal y el perímetro escrotal cada 28 días (P1 a P9), y los niveles de testosterona plasmática cada 14 días (P7 a P9). La ganancia de peso promedio varió de 0,92 a 0,97 kg/animal/día. El peso corporal y el perímetro escrotal promedio no mostraron diferencias (P>0,05). Los animales del T2 presentaron niveles medios de testosterona más elevados (2,2 ng/mL) frente a Control (1,8 ng/mL) y a T1 (1,6 ng/mL) (P<0,05). Fueron observadas correlaciones positivas entre el peso corporal y los niveles de testosterona (r = 0,58; P<0,0001) y entre la testosterona y el perímetro escrotal (r = 0,16; P<0,02). En conclusión, los suplementos alimenticios probados promueven un desempeño semejante al concentrado tradicional, cuando se considera el desempeño zootécnico y la evaluación de la biometría testicular en toros bufalinos jóvenes. Sin embargo, el uso de la torta de palmiste fue capaz de elevar los niveles séricos de testosterona.

ABSTRACT

The aim of the study was to evaluate the effects of dietary supplements based on copra meal or palm kernel cake on body weight, scrotal circumference and testosterone levels of buffalo bulls kept in intensive rotational grazing. Fifteen buffaloes (457.8±98.3 kg and 3.2±1.3 years) grazing areas of Panicum maximum vr. Mombaza received daily supplementation (1% of body weight) in individual feeders. Animals were randomly assigned to three treatments: Control (n = 5; conventional concentrate based on ground corn and soy-bran), T1 (n = 5; concentrate based on copra meal) and T2 (n = 5; concentrate based on palm kernel cake). The experiment was conducted during 252 days, divided in nine periods of 28 days (P1 to P9). The feed intake was monitored daily, the body weight and scrotal circumference every 28 days (P1 to P9) and plasma testosterone levels every 14 days (P7 to P9). The average weight gain varied from 0.92 to 0.97 kg/animal/day. The average body weight and scrotal circumference did not differ between treatments (P>0.05). Animals in T2 had higher average levels of testosterone (2.2 ng/mL) compared to Control (1.8 ng/mL) and T1 (1.6 ng/mL) (P<0.05). Positive correlations were observed between body weight and testosterone levels (r = 0.58; P<0.0001) and between testosterone and scrotal circumference (r = 0.16; P<0.02). In conclusion, the new dietary supplements promoted performance similar to the conventional concentrate, considering the body weight gain and the testicular biometry in young buffalo bulls. However, the use of palm kernel cake was more efficient in raising serum testosterone levels.
