“…Resultados superiores foram obtidos por Zambom et al (2015) que obtiveram média de 19,9 mg/dL de N-ureico no plasma de vacas Holandesas alimentadas com silagem do resíduo da extração do amido de mandioca, substituindo 0%, 25%, 50%, 75% ou 100% do milho da ração. A menor média encontrada no presente trabalho, possivelmente, foi devido ao menor teor médio de PB das dietas (13,5%) (Quadro 2) quando comparada a concentração de PB (16,1%) das rações da pesquisa de Zambom et al (2015).…”

RESUMO.-Avaliou-se o efeito da inclusão da silagem da raiz de mandioca sobre os parâmetros ruminais e o balanço de compostos nitrogenados em bovinos de origem leiteira. Utilizou-se cinco animais, canulados no rúmen, não lactantes e com peso corporal médio de 389 kg. Os animais foram distribuídos em um quadrado latino cinco x cinco, sendo cinco dietas com níveis de inclusão (0,00; 3,62; 7,23; 10,84 The effect of inclusion of cassava root silage on ruminal parameters and nitrogenous compounds in dairy cattle was evaluated. Five cattle cannulated in the rumen and with average body weight of 389 kg were distributed into a Latin square 5x5, with five levels of inclusion (0.00, 3.62, 7.23, 10.84 and 14.54% of the diet dry matter) of cassava root silage and five periods (10 days for adaptation and five days for data collection). The nitrogen excretion in urine and feces were not affected (P>0.05) by inclusion of cassava root silage in the diet. The total nitrogen intake (CNT) and nitrogen balance (NB) showed an increasing quadratic and linear behavior, respectively. The lowest CNT (142.14g/day) was obtained with the inclusion of 5.82% silage cassava root. The concentration of urea (U) and urea nitrogen (UN) in plasma and urine did not change (P>0.05). There was a quadratic behavior (P<0.05) in excreta of U and NU in the urine, with minimum point of 131.13 and 61.20g/day respectively, at the level of 7.27% inclusion of the cassava root silage. No interaction (P>0.05) was between the levels of cassava root silage and the collection time of rumen contents for the short-chain fatty acids, pH and ammonia nitrogen (NH3-N). Only the N-NH 3 protein showed quadratic behavior, according to the inclusion levels, with the minimum point (12.62mg/100ml of rumen contents) at the level of 5.98%. The level of 7.23% of cassava root silage in the diet was more efficient with the use of nitrogen compounds. The diets contribute similarly to the production of short chain fatty acids, without disturbing the rumen pH.

“…There are no studies in the literature evaluating cassava root silage for ruminants. But, Zambom et al (2015) evaluated the replacement of corn with silage made with the residue from the extraction of cassava starch in the diet for cows and reported increases in production and improvements in the composition of milk.…”

The objective of this study was to evaluate the effect of replacement of corn with pre-dried cassava root silage (CRS) on intake, ingestive behavior, production and composition of goat milk. Five lactating Saanen goats were used, with 42.5 ± 4.2 kg body weight and production of 2 kg milk day-1, distributed in a 5 x 5 Latin square with five treatments: 0, 28.6, 58.0, 81.6 and 100% replacement of corn with CRS in the diet dry matter. Goats were monitored for five periods of 15 days each. The intake of dry matter, crude protein and neutral detergent fiber decreased linearly (p <0.05) with the replacement of corn with CRS. Feeding (348.5 ± 62.1 min.) and rumination (468.8 ± 83.8 min.) times were not influenced (p >0.05) by the replacement of corn with CRS, but the ingestion and rumination efficiencies had a linear increase (p > 0.05). Milk production (2.17 ± 0.45 kg day-1), fat (3.49 ± 0.42%), protein (3.11 ± 0.13%) and lactose (4.47 ± 0,11%) of goat milk were not influenced (p >0.05) by the replacement of corn with CRS. Therefore, it is recommended the total replacement of corn with pre-dried cassava root silage in the diet for dairy goats with an average production of 2 kg day-1.

“…Cassava roots are widely used as a source of starch in regions where it is grown. The by-product of cassava starch extraction (CSE) is used in feeding livestock in these regions, such as in southern Brazil (Gonçalves et al, 2014;Zambom et al, 2014;Zambom et al, 2015). However, because the dry matter content of cassava by-product is low (average 150 g/kg) (Jasko et al, 2011), its on-farm preservation and storage can be challenging.…”

This study evaluated silages made with varying proportions of viticulture by-products (VC) and starch extraction from cassava (CSE). It attempted to determine the effects of these proportions on the microbial population, fermentative losses, and chemical composition. The treatments were specified as the proportions of VC in the silage (0 g/kg, 250 g/kg, 500 g/kg, 750 g/kg, and 1000 g/kg). Silages were evaluated before (0) and after 1, 3, 7, 15, 30, and 60 days of ensiling. The experimental design was completely randomized with five treatments, six storage times and four replications. The increased level of VC in the silage enhanced its dry matter content, ammonia nitrogen (NH3-N), and buffering capacity, and reduced organic matter content. Fifteen days after ensiling, additional VC increased the concentration of soluble carbohydrates. The increased level of VC decreased the count of Clostridium spp. and lactic acid bacteria (LAB). The incidence of yeasts and enterobacteria was low in all treatments at all time points. Over time, losses as effluent and gases increased. Use of increasing proportions from VC in silage made with CSE increased the contents of dry matter and soluble carbohydrates and reduced the fermentative losses of the silage. The increased amount of VC also favoured pH reduction and reduced the proliferation of undesirable yeasts, while increasing the population of LAB.
