“…Protein supplementation did not have any effect on forage intake. This agrees with the results of Ventura et al (1975) who observed that protein supplementation improved intake of low quality hay but had no effect on intake of good quality hay by sheep. According to Povey et al (1990) and Chestnutt (1992), fish meal supplementation has no effect on DM intake of silages averaging 15% CP, which is close to the CP value of our forages ( Table 1).…”

. 1998. Performance of lambs fed either hay or silage supplemented with canola or fish meals. Can. J. Anim. Sci. 78: 135-141. Forty-eight lambs (29.0 ± 4.7 kg BW) were used to study the effects of protein supplementation of forages on performance and diet digestibility. Lambs were fed grass hay or silage ad libitum plus a daily supplement of either: C, a control supplement supplying 1.2 g kg -1 BW of dry molasses and 0.6 g kg -1 BW of minerals, vitamins and lasalocid; CM, control supplement + 5.48 g kg -1 BW of canola meal; or FM, control supplement + 3 g kg -1 BW of fish meal. Apparent digestibility of all dietary components was higher in lambs fed silage than in those fed hay (P < 0.04). Addition of CM or FM improved apparent digestibility of energy and crude protein (CP) of lambs fed hay (P < 0.02) and CP digestibility of lambs fed silage (P < 0.01). Apparent digestibility of CP was higher in lambs fed FM than in those fed CM with either hay or silage (P < 0.03). Addition of CM or FM tended to decrease ADF digestibility of silage-based diets (P < 0.06). Apparent ADF digestibility of hay-based diets was lower in lambs fed CM than in those fed FM (P < 0.02). Forage DM intake was similar for all treatments. Addition of CM or FM to the diets improved average daily gains by 24% (P < 0.03), an effect that was higher with hay (35.1%, P < 0.02). Feed efficiency was 23.6% better in lambs fed protein-supplemented hay than in those receiving C (P < 0.04). Neither dressing percentage nor carcass lean yield was affected by protein supplementation. Digestible DM and TDN intakes were higher in lambs fed silage (P < 0.03) as a result of higher apparent digestibility for silage than hay. Furthermore, CM increased TDN intake by 7.6 and 8.2% in lambs fed hay and silage, respectively, compared with lambs fed FM. Addition of canola and fish meals improved forage nutritive value for lambs.Key words: Canola meal, fish meal, forages, digestibility, lambs, growth Agbossamey, Y. R., Petit, H. V., Seoane, J.

La digestibilité apparente de toutes les composantes de la ration a été plus élevée chez les agneaux recevant de l'ensilage que pour ceux recevant du foin (P < 0,04).

“…In the current experiment, when a supplementation effect was realized, whether alone (as in Tifton 85 DM) or as an interaction (as in Tifton 85 NDF and ADF), there was a decrease in the overall degradation of the forage. When supplemented with approximately 1.7 g kg -1 BW as soybean meal, wethers consumed less immature hay (TDN/CP = 3.5:1), while mature hay with TDN/CP of 9:1 was consumed at a greater rate (Ventura et al, 1975). Similarly, no effect of supplemental protein was realized for bermudagrass hay intake with TDN/ CP below 8.5:1 (Moore et al, 1991).…”

Season of forage growth and supplementation have the potential to affect digestion and animal performance. The objectives were to evaluate the ruminal digestion kinetics of 'Tifton 85' bermudagrass (T85) [Cynodon dactylon (L.) Pers. × C. nlemfuënsis Vanderyst] as affected by seasonality and rate of supplemental dried distillers' grains with solubles (DDGS). Samples were harvested in June, August, and October 2014. Six ruminally-fistulated steers were allocated to three pens. Pens (experimental unit) were randomly assigned one of three rates of DDGS: 0, 2.5, or 10 g kg -1 body weight (BW) as fed. Duplicate samples of each seasonality were inserted into the rumen of each animal en masse and removed sequentially after 2, 4, 8, 12, 24, 72, or 96 h. Degradation of dry matter (DM) decreased with increasing seasonality (P ≤ 0.01) and DDGS (P ≤ 0.04). The indigestible fraction (U) of DM from T85 was least (P < 0.05) for June (190 g kg -1 ), followed by August (337 g kg -1 ), and greatest for October (407 g kg -1 ). The U from T85 DM was not different (P = 0.47) based on rate of DDGS (312 g kg -1 ). There was an interaction of seasonality and DDGS for T85 NDF (P = 0.01) and ADF disappearance (P < 0.01). Increasing DDGS improved degradation of June but not October seasonality. Harvests from later in the season may have altered the cell wall structural profile, and increases in DDGS supplementation might have created an inhospitable rumen environment for fiberdegrading bacteria.

“…Os resultados deste trabalho agregam aos obtidos por Ventura et al (1975), que, forneceram suplemento a ovinos alimentados com capim-pangola (Digitaria decumbens) com farelo de soja (aproximadamente 0,1% do PC em PB) e não verificaram alteração do consumo de forragem quando esta apresentava 13,7% de PB. Contudo, influências negativas da suplementação foram verificadas por esses autores quando a forragem basal apresentava 17,8% de PB.…”

RESUMO -Objetivou-se avaliar o efeito de diferentes relações entre proteína verdadeira e nitrogênio não-proteico sobre o consumo e a dinâmica de trânsito e degradação ruminal da fibra em detergente neutro (FDN) da forragem em bovinos em pastejo durante o período das águas. Foram utilizados cinco novilhos mestiços Holandês × Zebu, castrados, com peso corporal inicial de 335±35 kg fistulados no rúmen e no abomaso. Os tratamentos foram: controle (somente pasto); e suplementos com ureia; com 2/3 de compostos nitrogenados oriundos da ureia e 1/3 de compostos nitrogenados oriundos da albumina; com 1/3 de compostos nitrogenados oriundos da ureia e 2/3 de compostos nitrogenados oriundos da albumina; e com albumina. effects of supplementation on voluntary intake, except for CP intake, which was increased by supplementation. The replacement of urea by albumin in the supplements caused linear effect on the CP intake. The intakes of the other diet components were not affected by the supplement composition. There was no effect on ruminal rate of passage of fibrous compounds. Supplementation increased the estimates of common rate of lag and degradation of NDF. However, no effect of supplement composition alteration was observed on this parameter. Supplementation of cattle with rumen degradable (protein or non-protein) nitrogenous compounds for grazing cattle during rainy season does not affect voluntary intake of pasture.
