Daily vs alternate day supplementation of soybean meal or wheat middlings to steers consuming low quality hayShirley, Tyson R. 22 July 2002 (has links)
Two experiments were conducted to determine the effects of daily (D) vs
alternate day (AD) supplementation of soybean meal (SBM) or wheat
middlings (WM) on forage organic matter intake (OMI), ruminal digesta
kinetics, total tract digestibility, and ADG of steers consuming low quality
forage. In Exp. 1, five Angus x Hereford steers (403 �� 32 kg) fitted with
rumen cannulas were utilized in a 5 x 5 Latin square design. Steers were
individually fed low-quality (5.3% CP) fescue hay ad libitum and were
randomly assigned to one of five treatments: no supplement (CON); WM
fed daily (WMD); WM fed every other day (WMAD); SBM fed daily (SBMD);
and SBM fed every other day (SBMAD). Supplements were formulated to
meet 100% of degradable intake protein (DIP) and metabolizable protein
(MP) requirements. Supplementation increased (P<0.05) hay and total
OMI (g���kg��������BW�����) and total OM digestibility (%) compared to CON. Daily
supplementation increased (P<0.05) hay and total OMI and hay and total
OM digestibility when compared with AD supplementation. Hay OMI and
hay OM digestibility was greater (P<0.01) for SBM compared to WM, but
total OMI and total OM digestibility was not different (P>0.38). In Exp. 2,
96 Angus crossbred steers (280 �� 32 kg) were blocked by weight (three
groups) into 12 pens in a randomized complete block design. Steers were
fed low-quality (6.2% CP) fescue straw ad libitum, and one of four
supplements formulated to meet 100% of the DIP requirements: WM fed
daily (WMD); WM fed 3d/week (WMAD); SBM fed daily (SBMD); and SBM
fed 3d/week (SBMAD). Straw OMI was greater (P<0.03) for D compared
with AD supplemented treatments and for SBM compared with WM
supplemented treatments. Total OMI was greater (P<0.01) for D
compared with AD supplemented treatments, however, SBM had similar
total OMI when compared with WM supplemented treatments. Daily
supplemented steers had greater (P=0.03) ADG when compared with AD
supplemented steers. Despite having lower forage intake and similar total
OMI, steers consuming WM had higher (P<0.01) ADG when compared to
steers consuming SBM. / Graduation date: 2003

martins_mb_dr_botfmvz.pdf: 430496 bytes, checksum: 854b1663c5c8ab5aaf809c07b751b003 (MD5) / Foi realizada avaliação da técnica dos isótopos estáveis de carbono em comparação ao indicador externo óxido de cromo (Cr2O3), aliados ao indicador interno fibra em detergente neutro indigestível (FDNi), na estimativa de consumo de bovinos em pastejo recebendo suplementação na fase de terminação. Foram utilizados 36 bovinos de corte da raça Guzerá, 18 machos e 18 fêmeas, com 20 meses de idade e média de peso vivo inicial de 358,18 kg e 317,83 kg, respectivamente, distribuídos em 12 piquetes, sendo 3 animais por piquete. Os animais foram mantidos em pastagem de Brachiaria brizantha (C4) sob método de pastejo de lotação contínua, recebendo suplementação (C3) na fase de terminação. Realizaram-se administrações de Cr2O3 aos animais por período de 10 dias, sendo realizadas nos últimos três dias, coletas de fezes para as análises. Ambas as metodologias possibilitaram estimativas de consumo semelhantes (P >0,05). Houve diferença (P <0,05) na estimativa do consumo de matéria seca entre os machos e fêmeas, sendo o maior consumo correspondente aos machos. Houve alta correlação entre consumo animal e ganho de peso médio diário (r = 0,80), e os valores de consumo e ganho foram menores no período mais crítico da seca, onde a pastagem encontrava-se com reduzida produtividade e qualidade nutricional. A estimativa de consumo do pasto por intermédio dos isótopos de carbono mostra-se viável na experimentação com animais em condições de pastejo, apresentando vantagens quanto a menor interferência ao comportamento animal / We evaluated the carbon stable isotope technique in comparison to the external indicators of chromium oxide (Cr2O3), together with the internal indicators indigestible neutral detergent fiber (NDFi), in estimated of the intake of cattle grazing and supplementation in the finishing phase. Thirty-six Guzerá breed beef cattle (18 males and 18 females) were used, with 20 months old and average initial weight of 358.18 kg and 317.83 kg, respectively, divided into 12 paddocks, 3 animals per paddock. The animals were reared at pasture dominated by Brachiaria brizantha (C4) under grazing continuous method, and supplemented (C3 feed) in the finishing phase. Cr2O3 were applied into animals for 10 days, and the last three days, fecal samples were collected for analysis. Both methodologies enabled similar intake estimates (P >0.05). There were differences (P <0.05) in the estimated dry matter intake between males and females, with the highest intake for males. There was a high correlation between intake and daily weight gain (r = 0.80), and the intake and weight gain values were lower in the most critical dry period, where the pasture had reduced productivity and nutritional quality. The estimate of the pasture intake through the C isotopes provides to be feasible in animal experiments under grazing conditions. Besides, this technique has advantage in terms of less interference to animal behavior
