“…Crude protein showed a small decrease when the NaOH treatment was applied. This observed decrease was consistent with previous studies and was a disadvantage of this treatment when compared with others, such as treatment with ammonia or urea, which are sources of non-protein nitrogen (Madrid et al, 1998). The decrease in NDF was most evident with the 8% concentration of NaOH.…”

This study evaluated the effects of sodium hydroxide (NaOH) treatment on the nutritional value of Arundo donax (A. donax). Its ultimate goal was to develop an environmentally friendly animal feed alternative that could be produced sustainably while combatting the spread of A. donax. Plants were collected and dried at 60 °C in an oven with controlled air circulation to determine the dry matter (DM) content. The dry plant material was then sprinkled with an NaOH solution of 2%, 4%, 6%, or 8% and placed in leak-proof containers for four weeks. The chemical and in vitro digestibility properties of treated and untreated A. donax samples were analysed in triplicate. The treatment led to significant decreases in neutral detergent fibre (NDF) from 81.06% DM to 69.39% DM, acid detergent fibre (ADF) from 46.99% DM to 43.19% DM, and ether extract (EE) from 2.06% DM to 1.39% DM, in the untreated samples compared with those treated with 8% NaOH, respectively. In addition, DM digestibility increased from 24.61% to 33.78%, ash content from 11.75% DM to 19.92% DM, and ADL from 7.43% M to 15.38% DM. Thus, treatment of A. donax with an 8% solution of NaOH concentration improved its nutritional value.

“…Observa-se que somente o teor de PB não sofreu influência (p>0,05) do tratamento com NaOH, fato já esperado, tendo em vista que a ação do NaOH sobre a deslignificação da hemicelulose e da celulose da parede celular não deve alterar a concentração de PB (concentração de nitrogênio multiplicado por 6,25), diferenciando-se dos tratamentos que utilizam produtos químicos, como a amônia ou a uréia, que incorporam nitrogênio não protéico ao material tratado (Madrid et al, 1998). Qualquer alteração nos teores de PB de feno tratado exclusivamente com NaOH, possivelmente, estaria associada à leve fermentação durante o tratamento (Chaudhry, 1998).…”

RESUMO -O experimento foi conduzido com o objetivo de avaliar o efeito do tratamento com hidróxido de sódio (NaOH) na fração fibrosa, no teor de tanino e na digestibilidade in vitro da matéria seca do feno de jurema-preta. As folhas foram colhidas manualmente e desidratadas à sombra. O tratamento químico consistiu na pulverização do feno com solução de 0; 2; 4; 6 e 8% de NaOH, na proporção de 1 litro da solução para 1 kg de feno. Amostras do feno foram submetidas à determinação da matéria seca (MS), proteína bruta (PB), fibra em detergente neutro (FDN), fibra em detergente ácido (FDA), tanino e digestibilidade in vitro da matéria seca (DIVMS), que se constituíram nas variáveis analisadas. O delineamento foi o inteiramente casualizado, com cinco tratamentos e quatro repetições. O tratamento com NaOH proporcionou efeito linear decrescente nos teores de MS, hemicelulose e tanino, enquanto, para FDN e FDA, ocorreu efeito quadrático. A PB não foi afetada e a DIVMS melhorou com o aumento da concentração de NaOH. A estimativa da DIVMS pelo teor de tanino, apesar de significativa, carece de mais estudos.Palavras-chave: fibra em detergente ácido, fibra em detergente neutro, leguminosa, NaOH Effect of Sodium Hydroxide Treatment on Fiber Fraction, Digestibility and Tannin ofJurema-Preta Hay (Mimosa tenuiflora. Wild)ABSTRACT -Experiment was carried out with the goal to evaluate the effect of sodium hydroxide (NaOH) on fiber fraction, tannin level and dry matter in vitro digestibility of jurema-preta hay. Leaves were harvested by hand and dried under shadow. Chemical treatment was done by pulverization of hay with 0; 2; 4; 6 and 8% NaOH solution following the proportion of 1 liter of solution to 1 kg of hay. Samples of hay were submitted to determinations of dry matter (DM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), tannin and DM in vitro digestibility which were the variables analyzed. Design completely randomized was used with five treatments and four repetitions. NaOH treatment caused linear effect in DM, hemicellulose and tannin contents; while for NDF and ADF was observed quadratic effect. CP was not affected and DMIVD was improved by NaOH concentration increase. DMIVD estimated by tannin content need to be more studied, instead of its significance.

“…There are reports on the increase in the intake of roughages treated with urea when supplemented with concentrates. Schiere and de Wit (1995), Madrid et al (1998), andSingh et al (2007) report an increase in treated straw intake when supplemented with energetic or protein by-products. Sanh et al (2002) found no differences in DM intake of crossbred dairy cows when urea treated rice straw substituted up to 75% of green tropical grass; although high levels of concentrate supplements may reduce the intake of treated roughages due to substitution and negative associative effects (Schiere and de Wit 1995).…”

Maize straw is the main roughage for dairy herds in campesino farms in central Mexico. The objective was to evaluate feeding milking cows on maize straw treated with 40 g/kg DM of urea (A) or untreated straw (B), and 3.0 kg/d of 18% CP concentrate. Twenty-four Holsteins in late lactation from 8 farmers were sorted in two groups: sequence A-B-A or B-A-B; periods were 28 days. Mean daily milk yield for the last two weeks per period, and live-weight and body-condition score every 14 days were used for analysis. Maize straw was ad libitum. Chemical analysis and in vitro digestibility were analysed by Student's t test, animal variables by a switch-back design. 'A' had 44.3 g/kg DM more CP and 106.5 g/kg DM higher in vitro digestibility than 'B' (710 g/kg DM +/- 0.75 'A' vs. 603.5 g/kg DM +/- 1.44 'B'). Despite higher digestibility and intake, there were no differences (P > 0.05) for milk yield, live-weight or body-condition score, although there were in straw intake (P < 0.05). Cows on 'A' ate 1.7 kg/cow/day more straw DM than on 'B'. Lack of response did not offset higher feeding costs although margins were high. Lack of response is attributed to short length of periods and late lactation of cows.
