Resumo: | The aim of this study was to evaluate different levels of feed restriction in the diet for F1 Holstein x Zebu cows during the winter on performance and economic viability. Data from Zootechnical book keeping, and from experiments conducted in the Experimental Field of Felixlândia, belonging to EPAMIG, were used. Total lactation of sixty F1 Holstein x Zebu cows receiving different diets was analyzed, by 2.00%, 2.25%, 2.50%, 2.75% body weight (BW), and a control group (3.4%; no feed restriction), allowing 5% leftovers in relation to the dry matter supplied, distributed in a completely randomized design. Data on milk production and feed cost were collected, evaluating the different periods that characterize the lactation of an animal. The highest milk production was found in the diet levels 3.4 %, and 2.75% BW, 3,636.00, and 3,271.50 kg, respectively. Lower milk production was observed at levels of 2.50%; 2.25%; 2.00% BW, respectively. The highest feed cost was verified without feed restriction followed by the levels of 2.75%, 2.50%, 2.25%, and 2.00% BW. The supply of the no feed restriction diet resulted in a performance superior to levels 2.75; 2.50; 2.25; 2.00% BW. The items profit, profitability were similar between all treatments, indicating that, when there is occasional feed shortage, a restriction in the diet supply of up to 2% BW provides economic security to the rural producer. |

Foram utilizados dados da escrituração zootécnica e de experimentos realizados no Campo Experimental de Felixlândia, pertencente à EPAMIG. Foi analisada a lactação total de sessenta vacas F1 Holandês x Zebu submetidas a diferentes ofertas de dieta, em 2,00%, 2,25%, 2,50%, 2,75% do peso corporal (PC) e um grupo controle com alimentação à vontade (3,4%), permitindo 5% de sobras em relação à matéria seca fornecida, distribuídos em delineamento inteiramente casualizado. Os dados de produção de leite e custo alimentar foram coletados, avaliando os diferentes períodos que caracterizam a lactação de um animal. A maior produção de leite foi verificada nos níveis de dieta 3.4% e 2,75% PC, sendo 3.636,00 e 3.271,50 kg, respectivamente. Produção de leite inferiores foram verificadas nos níveis de 2,50%; 2,25%; 2,00% do PC. O maior custo com alimentação foi verificado no nível de alimentação à vontade seguido dos níveis de 2,75%; 2,50%, 2,25% e 2,00% do PC. A oferta da dieta sem restrição teve um rendimento superior aos respectivos 2,75 níveis; 2,50; 2,25; 2,00% do PC, respectivamente. Os itens lucro, lucratividade e rentabilidade foram semelhantes entre todos os tratamentos, demonstrando que, quando há escassez eventual de alimento, a restrição no fornecimento da dieta de até 2% do PC oferece segurança econômica ao produtor rural que utiliza vacas em seu sistema F1 Holandês x Zebu.UEL2023-01-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa científicaapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/4584410.5433/1679-0359.2022v43n6p2755Semina: Ciências Agrárias; Vol. 43 No. 6 (2022); 2755-2768Semina: Ciências Agrárias; v. 43 n. 6 (2022); 2755-27681679-03591676-546Xreponame:Semina.
