Suplementos para ovinos mantidos em pastos de capim-marandu [PDF]

Pesquisa Agropecuária Brasileira, 2011
O objetivo deste trabalho foi avaliar o efeito da suplementação na resposta produtiva, no pH e no nitrogênio amoniacal ruminal, e no custo de produção de ovinos em pastagem de capim-marandu no período da seca. O experimento teve a duração de 84 dias. Utilizaram-se 20 cordeiros não castrados com idade e peso corporal inicial médios de quatro meses e 24 ...

Homecoming of Brachiaria: improved hybrids prove useful for African animal agriculture [PDF]

, 2014
Species of the genus Brachiaria originate primarily from Africa, where they are constituents of natural grasslands. Due to their adaptation to acidic, low-fertility soils, millions of hectares of Brachiaria species have been sown as improved pastures in ...

Aspectos da Reprodução em Brachiaria brizantha cv. Marandu [PDF]

Acta Botanica Brasilica, 2001
Two modes of reproduction are found in plants, sexual and asexual. Apomixis is an asexual reproduction mode through seeds. Apomictic plants give rise to embryos identical to the mother plant through parthenogenesis of a non-reduced egg cell. This feature is very important to agriculture, once incorporated in genotypes of agronomic importance, it allows

Effects of eucalyptus thinning on soil chemical attributes in an unfertilized silvopastoral system 6 years after thinning

Soil Science Society of America Journal, Volume 90, Issue 1, January/February 2026.
Abstract Tree thinning is a common practice in silvopastoral systems, but there is no standard percentage of thinning used by farmers. Moreover, it is unclear how the percentage of thinning affects soil chemical attributes throughout the soil profile and throughout the transect between eucalyptus lines.

Genetic Parameters of Resilience Indicators Across Growth in Beef Heifers and Their Associations With Weight, Reproduction, Calf Performance and Pre‐Weaning Survival

Journal of Animal Breeding and Genetics, Volume 143, Issue 1, Page 79-91, January 2026.
ABSTRACT In tropical extensive beef cattle systems, heifers raised on pasture are exposed to various environmental challenges that affect their growth and reproductive performance during the first breeding. Resilience indicators derived from deviations in longitudinal traits can quantify the magnitude of these challenges and the ability of an animal to

Tolerância de três acessos de Brachiaria spp. ao alagamento do solo, em condições controladas. [PDF]

, 2013
O excesso de água no solo em pastagens tropicais é a principal condição para instalação da síndrome da morte do capim Brachiaria brizantha cv. Marandu. Assim, objetivou-se comparar a tolerância relativa de três genótipos de Brachiaria: B.
