Reyes Yordaine Ibarra Ana Valeria Enríquez Sara Rey Verena Torres Estudios Agrarios cost Intake balance production dairy quality A simulated grazing was developed with Brachiaria decumbens cv. Basilisk, to study the performance of dairy cows during rainy season in two grazing intensities: T1 = 75 and T2 = 150 LAU ha-1 day-1. Twenty Siboney crossbred cows were studied, between the second and third lactation, with 480 ± 8 kg of body weight (10 animals treatment-1), grazing 15 hours a day. InfoStat statistical program, version 12.0, was used for data processing. T2 animals showed lower grass availability (P = 0.0072) and intake decrease (P = 0.0362) (24.35 vs. 17.57 and 12.77 vs. 11.33 kg DM animal-1 day-1 for availability and intake of animals of 75 and 150 LAU ha-1 day-1). No differences were reported in individual production per cow and dairy components. However, production per area increased (P = 0.0001) by 1.74 times in T2 with respect to T1 (3,279.99 and 5,722.71 kg of milk ha-1 rainy season-1, for T1 and T2, respectively). Production cost of a liter of milk increased by 11.8 % in the treatment with the lowest intensity (2.17 vs. 1.96 $ L-1, for 75 and 150 LAU ha-1 day-1). Results indicate that animals from the treatment with 150 LAU ha-1 day-1 showed no differences in individual production, although they increased productivity per grazing area by 2,842.72 L, and decreased costs by 0.21 $ produced L-1. 2021 artículo científico 0864-0408 https://www.redalyc.org/articulo.oa?id=653769747002 https://www.redalyc.org/journal/6537/653769747002/ https://www.redalyc.org/journal/6537/653769747002/html/ https://www.redalyc.org/journal/6537/653769747002/653769747002.epub https://www.redalyc.org/journal/6537/653769747002/movil 10.7440/res64.2018.03 en http://www.redalyc.org/revista.oa?id=6537 Cuban Journal of Agricultural Science application/pdf Instituto de Ciencia Animal Cuban Journal of Agricultural Science (Cuba) Num.3 Vol.55 |
