In this sense, the study aimed to evaluate the nutritional effectiveness of Boer goats on a property located in Queimadas, Paraíba. The research involved detailed analysis of the weights of eight animals over three visits with 15-day intervals between them. It is worth mentioning that the nutritional management adopted in a semi-intensive system must combine native pastures with strategic supplementation of native forages and energy and protein concentrates, aiming to guarantee a balanced diet, especially in periods of water scarcity. Thus, the results highlighted significant variations in animal weight gains, emphasizing the critical importance of nutritional management adapted to local conditions. Furthermore, analysis of forage plants revealed marked differences in fresh mass, relative humidity and dry mass content between species such as Mimosa caesalpiniifolia Benth. and Prosopis juliflora. These results highlight the need for careful and adaptable management to regional particularities to optimize productivity and nutritional quality in beef goat farming. It is concluded that nutritional strategies are fundamental to promote sustainable and efficient management of beef goat farming in the semiarid northeastern region, contributing to the economic and environmental viability of this activity in the region.</em></strong></p> Fernando Amon, Humberto Cardoso de Cardoso, Giordan Flávio Garcez Lira, Yasmin Hosana Nascimento Porto, Francisco de Assys Romero da Mota Sousa, Flora Juenemann Klengues, Bruna Santos da Silva, Thaysa Karolina de Barros Neves, Larissa Silva Nelo Oliveira, Thyago Araújo Gurjão Copyright (c) 2025 Fernando Amon, Humberto Cardoso de Souza, Giordan Flávio Garcez Lira, Yasmin Hosana Nascimento Porto, Francisco de Assys Romero da Mota Sousa, Flora Juenemann Klengues, Bruna Santos da Silva, Thaysa Karolina de Barros Neves, Larissa Silva Nelo Oliveira, Thyago Araújo Gurjão https://creativecommons.org/licenses/by-nc-sa/4.0 https://www.southamericansciences.com.br/index.php/sas/article/view/202 Mon, 26 May 2025 00:00:00 -0300
