“…In agreement, Almeida et al (2015) when evaluating the dispersal of tropical forage legume seeds after ingestion by cattle, obtained after a period of 48 h for complete defecation of the seeds, a greater accumulated percentage of emerged seedlings of the calopogonium species with 1.64%, and the worst result for perennial soybean seeds with 0.06%. According to the authors, the passage through the digestive tract of cattle may have contributed to the reduction of germination of the legume seeds studied.…”

Currently, sustainable practices combined with an efficient livestock can have benefits for farmers as observed in this study in which the animals themselves spread the seeds in the pasture in order to promote an addition of forage resources in the canopy. The objective of this study was to evaluate seed germination of three forage species [Avena strigosa Schreb (black oat), Calopogonium mucunoides (calopogonium) and Neonotonia wightii (perennial soybean)] following ingestion by cattle. The feces were collected from the animals at intervals of 6 hours up to 48 hours after the ingestion of the seeds. The feces were placed in beds in the field for further germination studies for the next 30, 60 and 90 days (post-planting periods). No difference (P > 0.05) was observed between the treatments species or between post-planting periods of the evaluation. For all the studied seeds, the germination was only verified in the time of up to 30 days after the placement of the feces in the field, where black oats obtained numerically the highest accumulated percentage (during 48 hours) with 10% of germinated seeds. It is concluded that the use of cattle as a disperser of forage seeds can help in the introduction of new forage in order to improve the production and the quality of the pastures. The moment of the cattle entrance in the pickets will depend on the forage species to be introduced and can vary from 6 to 12 hours after the intake of the seeds.

“…Segundo Almeida et al (2015), existem características inerentes a cada espécie de leguminosa que influenciam sua sobrevivência no trato digestivo de animais. Estas particularidades estão relacionadas principalmente ao tamanho, formato das sementes (figura 2) e número de sementes ofertadas.…”

Efeito da mastigação sobre a sobrevivência de sementes de leguminosas forrageiras tropicais e germinação

Objetivou-se neste estudo selecionar sementes de leguminosas forrageiras através da resistência à ação mecânica após mastigação simulada e pela percentagem de germinação para inclusão em processo de dispersão endozoocórica realizadas por bovinos em dois experimentos. Foram avaliadas as leguminosas kudzu tropical (Pueraria phaseoloides), soja perene (Neonotonia wightii), flemingia (Flemingia macrophilla), estilosantes Campo Grande (Stylosanthes cv. Campo Grande) e macrotiloma (Macrotyloma axillare). No primeiro experimento avaliou-se o percentual de sementes destruídas pela mastigação simulada e, no segundo, o percentual de germinação após a mastigação simulada. Foram utilizados os seguintes tratamentos: sementes intactas (controle), escarificadas com lixa, mastigadas e escarificadas com lixa e sementes mastigadas. Não houve diferença (p>0,05) entre macrotiloma, flemingia e kudzu tropical, além destas leguminosas apresentarem maior porcentagem de sementes não destruídas em relação ao estilosantes e soja perene. O controle do estilosantes Campo Grande apresentou maior percentual de germinação e não diferiu (p >0,05) das sementes mastigadas e mastigadas e escarificadas. Não houve diferença estatística (p>0,05) entre kudzu tropical e flemingia; o estilosantes cv Campo Grande apresentou a maior porcentagem de sobrevivência. A técnica de mastigação simulada prevê alguns danos que as sementes passarão no trato digestivo de bovinos, o que serve de auxílio para a escolha das espécies de leguminosas que podem ser incluídas em dietas de bovinos para dispersão endozoocórica.

“…These authors suggest that cattle cannot considered legitimate seed dispersal. Almeida et al (2015) studied the introduction of legumes in established Brachiaria decumbens pasture by dispersing in cattle feces. They found that all pulses are found in fecal plates.…”

This experiment was conducted to evaluate the recovery and survival of tropical forage legume seeds (butterfly pea, stylosanthes, perennial soybean and macrotiloma) subjected through the digestive tract of cattle and to evaluate the germination of the seeds in feces of cattle. A 50 g of seed mixed with 150 g of mineral supplement offered to the cattle. Each cattle was considered as repetition. The bovine feces collected up to 60 hours after eating the seeds, where the seeds separated by sieves, using water, gloves procedure and tweezers. Later, they counted and divided into intact and swollen. For the germination test of the recovered seeds, 75 seeds per replicate were used (25 in natura, 25 intact and 25 swollen seeds, respectively). For the germination test in fecal plates, the bovine feces collected between 12 and 30 hours after eating the seeds. After 120 days, we evaluated the total amount of plants emerged within the study period (between 12 and 30 hours) and the average number of emerged plants per fecal signs. The results showed that cattle are facilitating the dispersion of butterfly pea, macrotyloma and perennial soybean, but not stylosanthes. The highest survival as the average number of germinated plants in fecal plates achieved by macrotyloma, followed by butterfly pea species and perennial soybean. The cattle were efficient in the pasture colonization process, due to the considerable dispersion of the seeds. This dispersion was not observed for seeds of stylosanthes.
