Resumo: | This study compared the effects of unchopped and chopped hay on milk production and composition, feed digestibility, and physiology of Lacaune sheep. Eighteen ewes were stratified by parity (two or three), days of lactation (60 ± 3.7 days), and milk production (1.04 L/ewe/day), and were randomly assigned to 1 of 2 treatments: 1) Unchopped or 2) Chopped Tifton 85 hay. Corn silage and concentrate were also provided. Chopped hay ewes gave lower (P≤0.01) dry matter intake and greater (P=0.02) crude protein digestibility. No effects of treatment were detected (P≥0.38) for the digestibility of dry matter, or of neutral and acid detergent fibers. Chopped hay ewes had greater (P≤0.01) milk production (d 7 and d 12), lactation persistence, and feed efficiency. Ewes eating chopped hay had greater (P=0.03) protein concentration in their milk. However, there were no effects of treatment × day and treatments (P≥0.16) for concentrations of fat, lactose, minerals, deffated dry extract, or density. Ewes eating chopped hay presented lower (P<0.01) serum concentrations of urea and tended to have lower (P=0.10) serum concentrations of glucose only on d 12. However, there were no effects of treatment × day and treatments (P≥0.16) for serum concentrations of total protein, albumin, globulin, triglycerides, or cholesterol. These data suggest that chopped hay promotes lower dry matter intake and serum concentrations of glucose and urea, but improves milk production, lactation persistence, feed efficiency, and protein concentration. |

Dieciocho ovejas fueron estratificadas por paridad (dos o tres), días de lactancia (60±3,7 días) y producción de leche (1,04 L/oveja/día), y fueron asignadas aleatoriamente a 1 de 2 tratamientos: 1) Sin picadura o 2) Tifton picado 85 heno. También se proporcionaron ensilaje de maíz y concentrado. Las ovejas de heno picadas dieron una menor ingesta de materia seca (P≤0.01) y una mayor digestibilidad de la proteína cruda (P=0.02). No se detectaron efectos del tratamiento (P≥0,38) para la digestibilidad de la materia seca o las fibras de detergente neutro y ácido. Las ovejas de heno picadas tuvieron mayor producción de leche (P≤0.01) (d 7 y d 12), persistencia de la lactancia y eficiencia alimenticia. Las ovejas que comían heno picado tenían una mayor concentración de proteína (P=0.03) en su leche. Sin embargo, no hubo efectos del tratamiento × día y los tratamientos (P≥0.16) para las concentraciones de grasa, lactosa, minerales, extracto seco desgrasado o densidad. Las ovejas que comían heno picado mostraron concentraciones de urea en suero más bajas (P<0.01) y tendían a tener concentraciones de glucosa en suero más bajas (P=0.10) solo en el día 12. Sin embargo, no hubo efectos del tratamiento × día y tratamientos (P≥0.16) para concentraciones séricas de proteínas totales, albúmina, globulina, triglicéridos o colesterol. Estos datos sugieren que el heno picado promueve una menor ingesta de materia seca y concentraciones séricas de glucosa y urea, pero mejora la producción de leche, la persistencia de la lactancia, la eficiencia alimenticia y la concentración de proteínas.Este estudo comparou os efeitos do feno inteiro e picado na produção, composição, digestibilidade dos alimentos e fisiologia do leite de ovelhas Lacaune. Dezoito ovelhas foram distribuídas em dois grupos pelo número de partos (dois ou três), dias de lactação (60±3,7 dias) e produção de leite (1,04 L/ovelha/dia): 1) feno não-picado ou 2) feno picado (Tifton 85). Silagem de milho e concentrado também foram fornecidos. Ovelhas que consumiram feno picado apresentaram menor (P ≤ 0,01) consumo de matéria seca e maior (P=0,02) digestibilidade da proteína bruta. Não foi verificado efeitos do tratamento (P≥0,38) para a digestibilidade da matéria seca ou das fibras detergente neutra e ácida. Ovelhas que ingeriram feno picado apresentaram maior (P ≤ 0,01) produção de leite (d 7 e d 12), persistência da lactação e eficiência alimentar. Ovelhas que comem feno picado apresentaram maior (P=0,03) concentração de proteína no leite. No entanto, não houve efeito do tratamento × dia e do tratamento (P≥0,16) para concentrações de gordura, lactose, minerais, extrato seco desengordurado ou densidade do leite. Ovelhas que ingeriram feno picado tiveram menores (P<0,01) concentrações séricas de ureia e tendência de menores (P=0,10) concentrações séricas de glicose no dia 12. No entanto, não houve efeitos do tratamento × dia e do tratamento (P≥0,16) para concentrações séricas de proteína total, albumina, globulina, triglicerídeos ou colesterol no soro. Esses dados sugerem que o feno picado promove menor consumo de matéria seca, concentrações séricas de glicose e ureia, mas melhora a produção de leite, a persistência da lactação, a eficiência alimentar, assim como aumenta concentração de proteínas.Research, Society and Development2020-07-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/500510.33448/rsd-v9i8.5005Research, Society and Development; Vol. 9 No. 8; e347985005Research, Society and Development; Vol. 9 Núm. 8; e347985005Research, Society and Development; v. 9 n. 8; e3479850052525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/5005/4884Copyright (c) 2020 Alexandre Bernardi, Antonio Silva, Catia Capeletto, Felipe Silva, Renata Defiltro, Gessica Perin, Ana Schogor, Marcelo Vedovatto, Aleksandro Schafer Da silvahttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessBernardi, AlexandreSilva, Antonio Waldimir Leopoldino daCapeletto, CatiaSilva, Felipe Junior Portela daDefiltro, Renata CristinaPerin, GessicaSchogor, Ana Luiza BachmannVedovatto, MarceloSilva, Aleksandro Schafer da2020-08-20T18:00:17Zoai:ojs.pkp.sfu.ca:article/5005Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:28:40.315746Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
