Using whole oats grain as a source of fiber in calves’ rations
Two experiments were carried out aiming to study the value of whole oats (wo) as a potential source of physically effective fiber (pendf) in rations for calves. In experiment 1, 24 Hereford calves (177 ± 18 kg) were randomly assigned to eight groups and these into one of four experimental rations (7...

| description | Two experiments were carried out aiming to study the value of whole oats (wo) as a potential source of physically effective fiber (pendf) in rations for calves. In experiment 1, 24 Hereford calves (177 ± 18 kg) were randomly assigned to eight groups and these into one of four experimental rations (79% concentrate), varying in the replacement level of grass hay (gh) for wo: 0:21, 7:14, 14:7, 21:0% dry matter (dm) basis wo:gh, respectively. Increasing wo level resulted in a quadratic response for pendf (P= 0.04) with values above 15% of dm. Intake increased quadratically (P= 0.03) and dm digestibility increased linearly (P= 0.03). As a result, feed conversion efficiency tended to improve (P= 0.08). In Experiment 2, four rumen cannulated steers were assigned in a crossover design to one of two experimental rations (65% concentrate) varying in pendf fiber source: 35% gh or 35% wo, aiming to study the fermentative pattern. Replacing gh for wo reduced mean daily rumen pH (5.9 vs. 6.3, P < 0.01), varying between 6.1 and 5.8, and always below pH values in gh. No differences were observed for the potentially degradable dm fraction, but fermentation rate was higher for wo (35.0 vs. 9.0 %/ h; P= 0.02), hence increasing effective degradability (58.3 vs. 65.4%; P= 0.048). Results from both experiments suggest it is viable to use wo as a pendf source for concentrated rations. |

En el experimento 1, 24 terneros Hereford (177±18 kg) fueron sorteados a ocho grupos y estos a una de cuatro raciones (79 % concentrado), definidas por niveles crecientes de sustitución de heno de moha (hm) por gea: 0:21, 7:14, 14:7, 21:0 % base materia seca (ms) gea:hm, respectivamente. Niveles crecientes de gea resultaron en una respuesta cuadrática de pefdn (P= 0,04) ubicándose por encima del 15 %. El consumo aumentó en forma cuadrática (P= 0,03) y la digestibilidad linealmente (P= 0,03). Como resultado, a mayor gea la eficiencia de conversión tendió a mejorar (P= 0,08). En el Experimento 2, cuatro novillos provistos de cánula ruminal se asignaron en un diseño crossover a dos raciones (65 % concentrado), difiriendo en la fuente de pefdn: 35 % hm o 35 % gea, con el objetivo de estudiar sus características fermentativas. La sustitución de hm por gea redujo el pH medio del rumen (5,9 vs. 6,3, P <0,01) variando entre 6,1 y 5,8, permaneciendo las 24 h por debajo de los valores registrados para hm. No se afectó la fracción de la ms potencialmente degradable en rumen, pero aumentó la tasa de fermentación para gea (35,0 vs. 9,0 %/h; P= 0,02), y la degradabilidad efectiva (58,3 vs. 65,4 %; P= 0,048). Los resultados de ambos experimentos sugieren que es viable el uso del gea como fuente de pefdn en raciones concentradas.Dois experimentos foram conduzidos como o objetivo de estudar o valor do grão inteiro de aveia (GIA) como fonte de fibra fisicamente efetiva (peFDN) em rações para bezerros. No experimento 1, 24 bezerros Hereford (177 ± 18 kg) foram sorteados em oito grupos e estes assignado ao acaso a quatro rações experimentais (79% de concentrado), definidas pelo aumento dos níveis de substituição de feno de moha (FM) pelo GIA: 0 : 21, 7:14, 14: 7, 21: 0% da matéria seca (MS) GIA: FM, respectivamente. O aumento do GIA resultou numa resposta quadrática de peFDN (P= 0,04) atingindo mais de 15%. O consumo aumentou quadraticamente (P= 0,03) e a digestibilidade linearmente (P= 0,03). Como resultado, quanto maior o GIA, a conversão alimentar tendeu a melhorar (P= 0,08). No experimento 2, quatro novilhos portadores de cânula ruminal foram designados num delineamento crossover a duas rações (65% concentrado) diferindo na fonte de peFDN: 35% FM ou 35% GIA, a fim de estudar as características fermentativas. A substituição de FM por GIA reduziu o pH médio do rúmen (5,9 vs. 6,3, P<0,01), variando entre 6,1 e 5,8, permanecendo 24 horas abaixo dos valores de FM. A fração da MS potencialmente degradável no rúmen não foi afetada, mas o GIA aumentou a taxa de fermentação (35,0 vs 9,0% / h; P= 0,02), e a degradabilidade efetiva (58,3 vs 65,4%; P= 0,048). Os resultados de ambos os experimentos sugerem que é viável o uso de GIA como fonte de peFDN em rações concentradas.Facultad de Agronomía, Universidad de la República - INIABeretta Virginia, Universidad de la República, Facultad de Agronomía, Montevideo, Uruguay. https://orcid.org/0000-0002-4762-5185Simeone Alvaro, Universidad de la República, Facultad de Agronomía, Montevideo, Uruguay. https://orcid.org/0000-0001-5240-5710Bentancur Oscar, Universidad de la República, Facultad de Agronomía, Montevideo, Uruguay. https://orcid.org/0000-0003-0509-5793Pancini Stefania, Universidad de la República, Facultad de Agronomía, Montevideo, Uruguay. https://orcid.org/0000-0001-9647-7169Banchero Noel, Universidad de la República, Facultad de Agronomía, Montevideo, Uruguay. https://orcid.org/0000-0002-6986-4654García Emiliano, Universidad de la República, Facultad de Agronomía, Montevideo, Uruguay. https://orcid.org/0000-0003-2765-0997Martínez Virginia, Universidad de la República, Facultad de Agronomía, Montevideo, Uruguay. https://orcid.org/0000-0002-7293-684XOneto Lautaro, Universidad de la República, Facultad de Agronomía, Montevideo, Uruguay. https://orcid.org/0000-0002-1553-88532024-05-08T17:40:12Z2024-05-08T17:40:12Z2021Artículoinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersione372application/pdfBeretta, V., Simeone, A., Bentancur, O. y otros.
