“…The concentrate used was based on corn, soybean meal, glycerine, urea, limestone and mineral salt ( Table 1). The glycerin was added to increase the energy density of the diet (Eiras et al, 2014a;b). The provided diet had a ratio of 40% forage (corn silage) and 60% concentrate.…”

This work was carried out to evaluate the animal performance, carcass characteristics and meat quality of crossbred heifers slaughtered at three different body weights. The heifers were slaughtered with 330 (Light), 360 (Medium) and 400 (Heavy) kg body weight. The final weight, average daily gain and carcass weight were greater for HEA heifers, intermediate for MED heifers and lower for LIG heifers. However, carcass dressing and pH were similar for the three heifers groups. Dripping loss, dissection loss and the muscle, fat and bone percentages on the 6th rib did not alter by slaughter weight. Slaughter weight did not affect the colour, shear force and lipid oxidation of meat. In conclusion, heavy heifers finished in pasture and that were concentrate-supplemented had better animal performance; however, the carcass characteristics and meat quality were similar for the three heifers groups.Peso de abate não alterou as características de carcaça e qualidade da carne de novilhas mestiças terminadas a pasto com suplementação RESUMO. Este trabalho foi realizado para avaliar o desempenho animal e características da carcaça e da carne de novilhas mestiças abatidas com três diferentes pesos vivos. As novilhas foram abatidas com 330 kg (LEV), 360 kg (MED) e 400 kg (PES). O peso vivo final, ganho médio diário e peso de carcaça foram superiores para as novilhas PES, intermediário para as novilhas MED e inferiores para as novilhas LEV. No entanto, o rendimento de carcaça e pH foram semelhantes para os três grupos de animais. As perdas por gotejamento, dissecação e as percentagens de músculo, gordura e ossos na 6ª costela não foram alteradas pelos três pesos de abate. Da mesma forma, o peso de abate não teve efeito sobre a coloração, força de cisalhamento e oxidação lipídica da carne. Em conclusão, novilhas mais pesadas terminadas em pastagem e suplementadas com concentrado apresentaram melhor desempeno animal; todavia, as características de carcaça e qualidade da carne não foram alteradas.Palavras-chave: análise instrumental, peso de abate, novilhas, qualidade da carne.

“…Glycerol is a byproduct from the biodiesel agroindustry and has been used as an energy source in diets of ruminants (Donkin, Koser, White, Doane, & Cecava, 2009;Eiras et al, 2013;Hales et al, 2013;Meale, Chaves, Ding, Bush, & McAllister, 2013;Cruz et al, 2014;Eiras et al, 2014). A reduction in NDF digestibility has frequently been reported from the inclusion of glycerine in ruminant diets (Donkin et al, 2009) apparently from a growth inhibition of cellulolytic bacteria.…”

ABSTRACT. Twelve ruminally cannulated steers (401.0 ± 41.5 kg) and 24 mo were used in a replicated arrangement truncated Latin Square with six animals in six treatments and four periods to evaluate the effect of crude glycerine (CG; 80.3% of glycerol) with starch or fiber-based energy ingredients in the concentrate on DMI, DM (DMD) and NDF digestibility (NDFD) and ruminal parameters. Experimental periods were 19 days (14 days for adaptation and 5 days to sampling). Diets were: CO -without CG and corn as ingredient of concentrate; CGC -inclusion of CG (10% of DM) with corn in the concentrate; and CGSH -inclusion of CG (10% of DM) with soybean hulls (SH) in the concentrate. All three diets were offered at low (LC) or high (HC) concentrate level, CL (40 or 60%). Animals fed LC or HC diets had similar DMI, DMD and NDFD. Animals fed diets with CG associated with corn or SH had higher propionate concentrations and lower A:P ratio. Diets with HC increase the propionate but do not affect the NDFD. CG (10% of DM) can be used to replace corn or SH in diets with 40 or 60% of concentrate, without affect NDFD.Keywords: acetate, glycerol, propionate, pH, soybean hulls.Fermentação ruminal de novilhos Nelore alimentados com glicerina bruta substituindo amido vs. ingrediente energético a base de fibra em dietas de baixo ou alto concentrado RESUMO. Doze novilhos canulados no rúmen (401,0 ± 41,5 kg) e 24 meses de idade foram usados em delineamento de quadrado latino truncado replicado com seis animais, seis tratamentos e quatro períodos, para avaliar o efeito da glicerina bruta (GB; 80,3% de glicerol) com amido ou ingredientes energéticos a base de fibra no concentrado sobre o CMS, digestibilidade da MS (DMS) e FDN (DFDN) e parâmetros ruminais. O período experimental foi 19 dias (14 dias de adaptação e 5 dias de coleta). As dietas foram: CO -sem glicerina bruta e milho como ingrediente do concentrado; GBM -GB (10% da MS) com milho no concentrado; GBCS -GB (10% da MS) com casca de soja no concentrado. As três dietas foram ofertadas em baixo (BC) ou alto (AC) teor de concentrado (TC; 40 ou 60%). Animais alimentados com BC ou AC apresentaram similar CMS, DMS e DFDN. Animais alimentados com GB com milho ou CS apresentaram maior concentração de propionato e menor relação A:P. Dietas com AC aumentou a concentração de propionato mas não afetou a DFDN. GB (10% da MS) pode ser usada para substituir o milho ou CS em dietas com 40 ou 60% de concentrado, sem afetar a DFDN.Palavras-chave: acetato, glicerol, propionato, pH, casca de soja.

“…Digestibility is a major indicator of the absorption and utilization of feed nutrients in animals, and is in uenced by factors such as feed quality and animal feeding (Lin et al, 2006;Eiras et al, 2014). At present, there is little research on the effect of TGR on the apparent digestibility in ruminants.…”

The purpose of this study was to investigate the effects of Tongmai granule residue (TGR) on the growth performance, apparent nutrient digestibility, blood biochemical parameters, and rumen fermentation in Doper x Small Tail Han hybrid sheep. Twenty-four healthy female lambs (6–7 months of age; 29.64 ± 1.80 kg initial body weight) were randomly divided into 3 groups and fed for 75 days. The control group was fed a commercial concentrate and the other groups were fed diets supplemented with 10% and 15% TGR respectively. Dietary 15% TGR supplementation decreased average daily gain, apparent digestibility of neutral detergent fiber, but increased the feed conversion ratio, apparent digestibility of crude fat and organic matter in lambs (P < 0.05). The 10% TGR group significantly increased the apparent digestibility of organic matter (P < 0.05). Dietary supplementation of 10% and 15% TGR significantly increased serum high density lipoprotein cholesterol (HDL-C) content on day 15, IgG content on day 30, and IgA content on day 60 of the feeding period (P < 0.05). Dietary supplementation of 15% TGR significantly increased the content of IgA on the 30th day (P < 0.05), and significantly decreased blood urea nitrogen (BUN) on the 30th day (P < 0.05) of the feeding period. TGR at 15% significantly decreased the contents of acetic acid, propionic acid, butyric acid, and total volatile fatty acids (TVFA) in the rumen (P < 0.05), and significantly increased the pH, NH3-N concentration, and acetic acid: propionic acid ratio (P < 0.05). The results suggest that, the addition of TGR to diet can improve the apparent digestibility of crude fat and organic matter, and improve the anti-atherosclerosis ability and immune function of Doper x Small Tail Han hybrid female lambs. The dietary addition of 10% TGR yielded the best feeding effect in this experiment.
