Resumo: | We evaluated the feeding behavior of F1 Holstein x Zebu lactating cows at 80 ± 12 days of lactation and average production of 20 ± 0.42 kg of milk / day, fed different sources of nitrogen compounds: soybean meal, sunflower meal, detoxified castor meal, and urea. We used two 4 x 4 Latin squares, consisting of four animals, four diets, and four experimental periods. The feeding behavior was obtained by visual evaluation to set the time spent eating, ruminating, idling and to assess ruminating chews and chewing time for ruminal boluses. There was no difference regarding the times spent in feeding (P = 0.1384), rumination (0.5964), idleness (P = 0.6314), number of periods in feeding (P = 0.5995), rumination (P = 0.4575), and idleness (P = 0.4251), duration of periods in feeding (P = 0.2711), rumination (P = 0.8699) and idling (P = 0.4025), depending on the used diet. There was no difference in milk production (P = 0.2755) of the cows among the experimental diets. The addition of sunflower meal to the diet, regarding the use of urea, results in lower consumption of NDF in minutes / kg (P = 0.0399) and, thus, a lesser feed efficiency of dry matter (P = 0.0069). Therefore, some feeding behavior characteristics of F1 Holstein x Zebu lactating cows can be changed by using different nitrogen sources; however, without harming the average production of 20 kg of milk corrected to 3.5% fat / day.Keywords: feeding; fiber; milk yield; protein sources; rumination. |

Utilizaram-se dois quadrados latinos 4 x 4, compostos de quatro animais e quatro dietas, com quatro períodos experimentais. O comportamento ingestivo foi obtido por avaliação visual para definir o tempo despendido em alimentação, ruminação, ócio e para avaliar mastigações merícicas e tempo de mastigação por bolo ruminal. Não houve diferença no tempo em alimentação (P = 0,1384), ruminação (P = 0,5964), ócio (P = 0,6314), número de períodos de alimentação (P = 0,5995), de ruminação (P = 0,4575) e de ócio (P = 0,4151), duração dos períodos de alimentação (P = 0,2711), ruminação (P = 0,8699) e ócio (P = 0,4025), em função da dieta utilizada. Não houve diferença na produção de leite (P = 0.2755) das vacas entre as dietas experimentais. A adição do farelo de girassol à dieta, em relação à utilização de ureia, resulta em menor consumo de FDN em minutos/kg (P = 0,0399) e consequentemente menor eficiência de alimentação da matéria seca (P = 0,0069), comparado ao tratamento com ureia. Assim, algumas características do comportamento ingestivo de vacas F1 Holandês x Zebu em lactação podem ser alteradas pelo uso de diferentes fontes nitrogenadas; entretanto, sem prejudicar a produção média de 20 kg de leite corrigida para 3,5% de gordura/dia.Palavras-chaves: alimentação; fibra; fontes protéicas; produção de leite; ruminaçãoUniversidade Federal de Goiás2016-07-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionResearchAvaliado por paresPesquisa originalapplication/pdftext/htmlhttps://revistas.ufg.br/vet/article/view/3605410.1590/cab17336054Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 17 No. 3 (2016); 349-358Ciência Animal Brasileira / Brazilian Animal Science; v. 17 n. 3 (2016); 349-3581809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/36054/21373https://revistas.ufg.br/vet/article/view/36054/21374Almeida Filho, Silvio Humberto Cardoso deRocha Júnior, Vicente RibeiroMenezes, Gustavo Chamon de CastroRuas, José Reinaldo MendesAguiar, Ana Cássia Rodrigues deSantana, Pedro FelipeBorges, Lucas Daniel AlcântaraCosta, Natanael Mendesinfo:eu-repo/semantics/openAccess2016-07-29T21:20:08Zoai:ojs.revistas.ufg.br:article/36054Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:56:10.767707Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true |
