Effect on Milk Yield of the Association of Brachiaria brizantha with Arachis pintoi in the Alto Mayo Region of the Peruvian Amazon Deysy Lara and Keneth Reategui FUNDAAM and DEPAAM, Peru The inclusion of legumes in pastures of Brachiaria decumbens and B. brizantha in the Alto Mayo region is a feasible alternative to increase animal productivity. This study therefore aimed to evaluate the effect of Arachis pintoi cv. Maní forrajero associated with Brachiaria on milk production and stocking rate of grazing cows. Materials and Methods The treatments evaluated were: T1, B. brizantha in monoculture; and T2, A. pintoi associated with several species of Brachiaria. Plots of the associated pasture, 4 ha in size, were established on a small farm in Soritor. Initial availability of forage, milk production, and stocking rate were recorded. Crossbred Gyr x Holstein cows were used in this evaluation. These same animals grazed both types of pastures. Each pasture was divided into two equivalent paddocks and animals grazed each paddock for 7 days. Milk production was measured in each paddock as of Day 3, during maximum precipitation. Forage availability and botanical composition were measured with random samplings in each paddock at the beginning of the grazing cycle. Results During the experimental period the producer controlled the rest/occupation periods and the number of animals grazing. The stocking rate of each pasture was calculated on the basis of these indicators: 2.07 AU/ha on pastures of B. brizantha and 4.13 AU/ha in the associated pasture. Forage availability and components of evaluated pastures indicated that total available DM in the associated pasture B. brizantha/A. pintoi was 7.59 t/ha at the beginning of grazing, with legumes accounting for 6% and weeds for 11% of the botanical composition of the pasture. The pasture of B. brizantha alone produced 6.29 t DM/ha, with 9% weeds. 70
Milk production during the season of maximum precipitation was, on average, 5.98 kg/cow per day when the cows grazed the associated pasture, compared with 4.99 kg/cow per day when they grazed the B. brizantha pasture. Conclusions Although these results are preliminary and correspond to a single evaluation, farmer expectations are high because the stocking rate of the associated pasture doubled that of the sole cropped pasture and milk production/cow increased by 10%. 71
