Resumo: A new spineless cactus genotype (Orelha de Elefante Mexicana) is being used in the diets of dairy animals raised in semiarid regions. However, little is known about its impact on goat milk production and feeding costs. The objective of this study was to evaluate the milk production and costs of feeding lactating Saanen goats with diets containing the spineless cactus Orelha de Elefante Mexicana (OEM) as a replacement for the Miúda (MIU) spineless cactus. Ten Saanen goats with an average initial weight of 50 ± 5.6 kg were assigned to two 5 × 5 Latin-square designs. The diets consisted of replacing MIU with four levels of OEM (0%, 11.5%, 23.5%, and 35%, on a dry matter basis) and a control based on Tifton hay. The diet with 35% OEM had lower costs per kg dry matter ($0.32) as well as lower daily feed costs ($0.29/d). The dry matter intakes and milk yields (3.21 kg/d) did not differ (P > 0.05) between the OEM replacement levels. The use of up to 35% MIU or OEM spineless cactus in the Saanen goat diet maintains milk production levels and decreases feed production costs.

Contudo, pouco se sabe sobre seu impacto na produção de leite de cabras e nos custos com alimentação. Objetivou-se com este estudo avaliar a produção de leite e os custos da alimentação de cabras da raça Saanen em lactação recebendo dietas contendo palma orelha de elefante mexicana (OEM) em substituição a palma miúda (MIU). Foram utilizadas dez cabras com peso inicial de 50 ± 5,6 kg distribuídas em duplo quadrado latino 5 x 5. As dietas consistiram em substituir MIU por quatro níveis de OEM (0%; 11,5%; 23,5% e 35%, com base na matéria seca) e uma dieta controle com feno de tifton. A dieta com 35% de OEM teve custos mais baixos por kg de matéria seca ($0,32), bem como menores custos diários de alimentação ($0,29/d). A ingestão de matéria seca e a produção de leite (3,21 kg/d) não diferiram (P>0,05) entre os níveis de substituição de OEM. O uso de até 35% de MIU ou OEM na dieta de cabras Saanen mantém os níveis de produção de leite e diminui os custos de alimentação.  Universidade Federal Rural do Semi-Árido2020-05-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/8908REVISTA CAATINGA; Vol. 33 No. 2 (2020); 550-554Revista Caatinga; v. 33 n. 2 (2020); 550-5541983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/8908/10223Copyright (c) 2020 Revista Caatingainfo:eu-repo/semantics/openAccessSoares, Luciana Felizardo PereiraCorrêa, Agni Martins NunesSouza, Andreia Fernandes deCarvalho, Francisco Fernando Ramos deMaciel, Michel do Vale2020-05-22T16:43:33Zoai:ojs.periodicos.ufersa.edu.br:article/8908Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2020-05-22T16:43:33Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)false
