“…The lack of effect of CaO on lignin content of forage was verified in other studies such as those found by Carvalho et al (2009), who when treating the crushed sugar cane with CaO (0, 1.25, 2.5 and 3.75% DM basis) for 12 and 36h did not observe any influence of the levels of CaO and periods of no treatment in lignin content. Mota et al (2010) obtained a similar result with the hydrolysis of sugar cane, lime or hydrated lime, where the lignin content showed no changes.…”

“…The lack of any significant effect on the EE content in sugar cane caused by the levels of CaO can be explained by the lack of this component in the additive, which did not have any contribution to the EE content in the material changed. Mota et al (2010), who used 0.5% for each treatment.…”

“…These studies aimed to improve animal production efficiency and reduce the damage caused by the ingestion of portions of non-digestible or non-degradable fiber, and to evaluate the contribution of additives in nutritional quality, digestibility and aerobic stability of both ensiled and fresh forage (Balieiro Neto et al, 2007, Carvalho et al, 2009Cavali et al, 2010, Mota et al, 2010.…”

The aim of this study was to identify the most adequate level of calcium oxide (CaO) in the treatment of sugar cane by evaluating the chemical composition and in vitro digestibility of dry matter. The sugar cane was homogenized with CaO levels 0, 0.75, 1.5, 2.25, 3.0, 3.75 and 4.5%, in natura matter, for 24 hours. The dry matter and mineral matter increased, while the organic matter of the sugar cane decreased (P <0.05) linearly as a result of the CaO levels. The CaO had no effect on the levels of crude protein and ether extract. The phosphorus concentration remained unchanged, but there was a significant increase (P<0.05) in the calcium content. The contents of neutral detergent fiber, acid detergent fiber and cellulose decreased linearly with the levels of CaO. The average levels of indigestible dry matter and indigestible neutral detergent fiber significantly decreased with increasing levels of CaO. The results showed that the in vitro dry matter digestibility (IVDMD) was different between fresh sugar cane and sugar cane with added levels of CaO from 1.5%. The IVDMD and nutritional value of the sugar cane was improved by adding 1.5% CaO based on fresh content.Keywords: additive, forage, hydrolysis, Saccharum, alkaline treatment CaO 0; 0,75; 1,5; 2,25; 3,0; 3,75 RESUMO O objetivo foi identificar o nível mais adequado de óxido de cálcio (CaO) no tratamento da cana-deaçúcar por meio da avaliação da composição química e a digestibilidade in vitro da matéria seca.

“…Esse material hidrolisado foi desidratado até atingir em torno de 30% da matéria seca e armazenado em tambor plástico de 200 litros com tampa removível para uso durante duas semanas. A ação do óxido de cálcio está relacionada à solubilização parcial da hemicelulose, promovendo o fenômeno conhecido como intumescimento alcalino da celulose -processo de expansão das moléculas de celulose, causando ruptura das ligações intermoleculares das pontes de hidrogênio, que conferem cristalinidade à estrutura e aumento na digestão da celulose e hemicelulose (Jackson, 1997;Mota et al, 2010).…”

ABSTRACT. This study evaluated the effect of different protein sources (soybean meal, cottonseed meal, peanut meal and sunflower meal) on dry matter and nutrient intake, productive performance and body measurements of dairy heifers, Holstein x Zebu, recreated in confinement. The experiment consisted in a randomized complete block design made up by 6 replications and 4 treatments. The mean values of ingestion of ether extract (EEI, kg day -1 ) were statistically different (p < 0.05). The neutral detergent fiber intake (NDFI, %BW) also presented differences (p < 0.05), with higher values in the diet containing sunflower meal (1.01% BW) in relation to the diet with soybean meal (0.84% BW). The average daily weight gain using the diet with soybean meal was superior (0.95 kg day -1 ) to the diet with sunflower meal (0.82 kg day -1 ), and considering the final body weight, the diet with soybean meal was superior to the other treatments (p < 0.05). The heart girth presented greater association with body weight (0.93). The soybean meal promoted the best productive performance of crossbred Holstein x Zebu heifers fed diets based on sugarcane. However, cottonseed meal, peanut meal and sunflower meal can be possible alternatives to soybean meal.Keywords: body measurement, daily gain, protein concentrate, sugarcane.Consumo de nutrientes, desempenho produtivo e medidas corporais de novilhas leiteiras alimentadas com diferentes fontes proteicas RESUMO. Objetivou-se avaliar o efeito de diferentes fontes proteicas (farelo de soja, farelo de algodão, farelo de amendoim e farelo de girassol) sobre o consumo de matéria seca e nutrientes, desempenho produtivo e medidas corporais de novilhas leiteiras, mestiças Holandês x Zebu, recriadas em confinamento. O delineamento experimental foi em blocos completos casualizados, constituído por seis repetições e quatro tratamentos. Os valores médios de ingestão de extrato etéreo (IEE, kg dia -1 ) apresentaram diferença estatística (p < 0,05). A ingestão de fibra em detergente neutro em % do peso corporal foi superior (p < 0,05) na dieta com farelo de girassol (1,01 %PC) em relação à dieta com farelo de soja (0,84 %PC). O ganho médio de peso corporal promovido pela dieta com o farelo de soja foi superior (0,95 kg dia -1
