Resumo: Nine of twelve lactating Holstein x Zebu cows grazing a Brachiaria plantaginea - Cenchrus ciliaris pasture were supplemented with 1.5 kg of coconut meal (group B), 4.8 kg of fresh Leucaena leucocephala (group C), and 0.75 kg of coconut meal + 2.4 kg of fresh leucena per cow/day (group D). The three remaining cows were given no supplement (group A). Effect of these treatments on milk yield were evaluated in a 4 x 4 latinsquare experimental design, with 14-day experimental periods. Forage availability (DM/ha) was over 1,782 kg. The milk yield of unsupplemented cows averaged 7.8 kg/cow/day, significantly lower than those of supplemented cows. The highest milk yield (P < 0.05) was observed in B cows (9.0 kg/cow/day). Cows on group C averaged 8.4 kg, which was shown to be the most profitable treatment under local marketing conditions. Cows on group D (8.3 kg/day) did not differ (P < 0.05) from those on group C, showing no benefit from the partial replacement of coconut meal.

O efeito dos tratamentos, na produção de leite, foi mensurado num delineamento em quadrado latino 4 x 4, com períodos experimentais de quatorze dias. A disponibilidade de forragem na pastagem esteve acima de 1.782 kg de matéria seca/ha, durante o período experimental (14/06 a 07/09/84). A produção média de leite das vacas não suplementadas (tratamento controle) foi de 7,8 kg/dia, entretanto, efeitos significativos (P < 0,05) foram observados a partir dos tratamentos com suplementação. A produção mais alta (P < 0,05) foi obtida de vacas suplementadas com 1,5 kg de farelo de coco (9,0 kg/dia). Não obstante, a suplementação com 4,8 kg de leucena fresca/vaca/dia, que propiciou produção de 8,4 kg de leite/vaca/dia, foi o tratamento mais rentável, em face às condições locais de mercado do leite. Não foi observado qualquer benefício na substituição parcial (50%) do farelo de coco por leucena fresca. Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFilho, Orlando Monteiro de CarvalhoLanguidey, Pablo HoentschCosta, João Albani2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/14063Pesquisa Agropecuaria Brasileira; v.23, n.10, out. 1988; 1181-1187Pesquisa Agropecuária Brasileira; v.23, n.10, out. 1988; 1181-11871678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/14063/8044info:eu-repo/semantics/openAccess2014-09-18T18:14:50Zoai:ojs.seer.sct.embrapa.br:article/14063Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-18T18:14:50Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
