Resumo: | The objective of this study was to evaluate milk production and forage production and accumulation in mombaça grass pastures managed at different pre-grazing heights. The design used was randomized blocks, with two entry heights 90 and 80 cm and the same grazing intensity 50%. Forage mass in the pre- and post-grazing condition was measured using five 1 m2 frames in each experimental unit. For the evaluation of the morphological components of the forage, subsamples were taken to determine pre and post-grazing forage masses. Grazing was pasted by 32 lactating F1 cows with an average weight of 550 kg. Mean pre-grazing heights observed were 92.97±5.7 and 81.88±4.6 cm for the 90 and 80 cm entry treatments, respectively. For the post-grazing heights of 45 and 40 cm, 45.75±3.75 and 40.70±3.70 cm were obtained, respectively. Forage productivity on pastures at heights of 80 and 90 cm was 5,822.1 and 7,205.4 kg /ha-1, respectively. On the other hand, dry mass in the pre-grazing condition differed between treatments with a higher value for 90 cm (4,114.5 kg/ha-1) in relation to 80 cm (3,368.1 kg/ha-1). Milk production was 13.2% higher for the lowest height. Mombaça grass pastures can be managed flexibly, with the animals entering and respecting the canopy height range of 80 to 90 cm without harming forage production. Mombaça grass pastures managed with lower pre-grazing heights (80 cm) promote higher milk production. |

El diseño experimental fue en bloques aleatorios. Las alturas de entrada fueron de 90 y 80 cm con una intensidad de pastoreo del 50%. La masa de forraje en las condiciones de prepastoreo y postpastoreo se midieron utilizando cinco marcos de 1 m2 en cada unidad experimental. Para evaluar los componentes morfológicos, se tomó una submuestra determinando asi la masa forrajera antes y después del pastoreo. El pastoreo fue realizado por 32 vacas F1 lactantes, con un peso promedio de 550 kg. Las alturas de prepastoreo observadas fueron de 92,97±5,7 y 81,88±4,6 cm para los tratamientos de 90 y 80 cm, respectivamente. Las alturas pospastoreo fueron de 45,75±3,75 y 40,70±3,70 cm para los tratamientos de 45 y 40 cm, respectivamente. La producción de forraje a alturas de 80 y 90 cm fue de 5.822,1 y 7.205,4/kg/ha-1, respectivamente. Por otro lado, la materia seca en condición de prepastoreo difirió entre los tratamientos, con un valor más alto que en la condición de prepastoreo, con valores de (3.368,1 kg/ha-1) para el tratamiento de 80 cm comparado con el tratamiento de 90 cm (4.114,5 kg/ha-1). La producción de leche fue un 13,2% superior en la altura más baja. Los pastos de hierba Mombasa pueden gestionarse de forma flexible, con animales que entran en el pasto respetando el rango de altura del past de 80 a 90 cm sin afectarla producción de forraje. Los pastos de hierba Mombasa manejados a alturas de prepastoreo más bajas (80 cm) favorecen una mayor producción de leche.Objetivou-se avaliar a produção de leite, a produção e o acúmulo de forragem em pastos de capim-mombaça manejados com diferentes alturas de pré-pastejo. O delineamento utilizado foi em blocos casualizados, com alturas de entrada de 90 e 80 cm e intensidade de pastejo de 50%. A massa de forragem na condição de pré e de pós-pastejo foi mensurada por meio de cinco quadros de 1 m2 em cada unidade experimental. Para a avaliação dos componentes morfológicos, foi retirada a subamostra para a determinação da massa de forragem de pré e pós-pastejo. O pastejo foi realizado por 32 vacas F1 em lactação com peso médio de 550 Kg. As alturas no pré-pastejo observadas foram de 92,97±5,7 e 81,88±4,6 cm para os tratamentos 90 e 80 cm respectivamente. Para a altura do pós-pastejo, observou-se 45,75±3,75 e 40,70±3,70 cm, respectivamente, para 45 e 40 cm. A produção de forragem nas alturas de 80 e 90 cm, foi de 5.822,1 e 7.205,4/kg/ha-1, respectivamente. Por outro lado, a massa seca na condição de pré-pastejo deferiu entre os tratamentos com valor superior à de pré-pastejo, observou-se valores de (3.368,1 kg/ha-1) para o tratamento de 80 cm em relação de 90 cm (4,114,5 kg/ha-1). A produção de leite foi 13,2% superior na altura mais baixa. Pastos de capim-mombaça podem ter manejo flexibilidade, com entrada dos animais respeitando o intervalo de altura do dossel de 80 a 90 cm sem prejuízos na produção de forragem. Pastos de capim-mombaça manejados com menores alturas (80 cm) de pré-pastejo promovem maior produção de leite.Research, Society and Development2024-01-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/4488610.33448/rsd-v13i1.44886Research, Society and Development; Vol. 13 No. 1; e15013144886Research, Society and Development; Vol. 13 Núm. 1; e15013144886Research, Society and Development; v. 13 n. 1; e150131448862525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/44886/35871Copyright (c) 2024 Rafaela Cristina Rodrigues; Daniel de Noronha Figueiredo Vieira da Cunha; Liana Jank; Márcia Vitória Santos; Isadora Menezes Costa Tarôco; Rodolfo Henrique Silva Pereira; Janaína Azevedo Martuscellohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessRodrigues, Rafaela Cristina Cunha, Daniel de Noronha Figueiredo Vieira da Jank, Liana Santos, Márcia Vitória Tarôco, Isadora Menezes CostaPereira, Rodolfo Henrique Silva Martuscello, Janaína Azevedo 2024-02-01T09:48:39Zoai:ojs.pkp.sfu.ca:article/44886Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-02-01T09:48:39Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
