“…For these same authors, increases in ADF content can be associated with the remaining leaves in pasture managed at greater heights, what reduces ecosystem quality over time. The higher the ADF content in forages, the higher the lignin content and hence the lower the substrate availability for ruminal digestion (MAGALHÃES et al, 2015).…”

This study aimed to evaluate the morphogenic, structural, chemical characteristics, and forage yield of Massai grass, as well as the performance of sheep under three pre-grazing canopy heights. Eighteen Dorper x crossbred sheep (12 males and 6 females) were subjected to three pre-grazing canopy heights of Massai grass (45, 35, and 25 cm). Rotational grazing was adopted, with a fixed rest period of 12 days and occupation of four days. Before placing animals in the paddock, stocking rate was estimated to ensure a reduction of about 50% in the initial height. Morphogenic and chemical characteristics of forage were evaluated, as well as animal intake and performance. Pasture managed at 25 cm height induced reductions in stem and sheath sizes, and phyllochron but an increased leaf: stem ratio. However, the pasture cut at 35 cm above ground promoted an increase in total dry mass and foliar leaf productions, in addition to greater forage availability and daily accumulation. Yet, pastures with a height of 45 cm had a higher percentage of stem and senescent material, decreasing leaf intake by animals. Among the studied heights, 35 cm is the most suitable for Massai grass, when used for rearing sheep for meat production under pasture conditions in the northern Tocantins. This is because this management provided a greater availability of good quality forage and thereby increasing weight gains per area in animals.

“…Moreover, ADF content is an indicator of forage energy and digestibility since the lower the ADF the higher the dietary energy and the lower the lignin content (MAGALHÃES et al, 2015). Forages with higher ADF contents also had a lower CP value and lower digestibility.…”

“…Values above 55% of cell wall content in the plant may limit DM consumption by the animal (Van Soest, 1982). Therefore, nitrogen confers an increase in the crude protein levels and leads to a decrease in the NDF and ADF contents of the leaves, as verified by Magalhães et al (2015), improving the quality of the forage consumable by the animals.…”

“…The higher lignin content in the banana peel reduces the NDF quality of the diets, impairing its digestibility. According to Magalhães et al (2015), the lignin content has a negative correlation with fiber digestibility. For each percentage unit of banana peel in the diet, there was a reduction of 0.2550% in crude protein digestibility (Table 4).…”

This study aimed to evaluate the effects of includingsun-dried banana peel in diets for F1 Holstein x Zebu cows on intake, digestibility and milk production. Diets were composed of 0, 15, 30, 45 and 60% replacement of sorghum silage with banana peel provided to 10 cows in two simultaneous 5 x 5 Latin squares, with the experiment divided into five periods of 16 days. The dry matter intake showed a quadratic effect with maximum level at 38.30% substitution as well as intake of crude protein expressed in kg -1 day and percentage of body weight, with maximum at the levels of 50.09 and 45.69% inclusion of the peel, respectively. The intake of neutral detergent fiber and the digestibility of neutral detergent fiber and crude protein showed a decreasing linear effect. Variation in weight and body condition score, milk production and feed conversion were not affected. The replacement of 60% sorghum silage with banana peel represents a viable alternative as it causes no change in cows with average production of 16.49 kg milk with 3.5% fat day -1 , reducing feeding costs. Key words: Co-product. Musa paradisiaca. Performance. Productivity. ResumoObjetivou-se avaliar os efeitos da inclusão de casca de banana seca ao sol na dieta de vacas F1 Holandês x Zebu, sobre consumo, digestibilidade e produção de leite. As dietas foram constituídas de 0, 15, 30, 45 e 60% de substituição da silagem de sorgo pela casca de banana. Foram utilizadas 10 vacas e o delineamento experimental foi em 2 quadrados latinos 5 x 5 simultâneos, sendo o período experimental dividido em cinco períodos de 16 dias. O consumo de matéria seca apresentou efeito quadrático com valor máximo no nível de 38,30% de substituição, assim como o consumo de proteína bruta expresso em kg dia -1 e em porcentagem do peso corporal, com valor máximo nos níveis de 50,09 e 45,69% de inclusão da casca, respectivamente. O consumo de fibra em detergente neutro e as digestibilidades da fibra em detergente neutro e da proteína bruta apresentaram efeito linear decrescente. As variações de peso e escore corporal, produção de leite e conversão alimentar não foram influenciados. A substituição de 60% da silagem de sorgo por casca de banana pode ser uma alternativa viável já que não altera produção de vacas com produção média de 16,49 kg de leite com 3,5% de gordura dia -1, reduzindo os custos com a alimentação.
