“…The addition of pineapple peel in the elephant grass ensiling achieved positive results, mainly when the level of inclusion reached 50%, with an increase in the crude protein content, close to 4.5%, was observed by Bonfá et al (2017). Yuangsoi et al (2018) also used pineapple residues in the diet of fish, at a level of inclusion from 1 to 2%, resulting in increased protein digestibility and fish growth, reduced ammonia level in water and, consequently, reduced nitrogen pollution.…”

The demand for products to replace high-cost raw materials, such oil and fish meal, in the manufacture of feed for use in aquaculture, while also guaranteeing the nutritional quality of the diets, is increasing. Silage produced with fish and vegetables residues is a low-cost and efficient protein source. The objective of the present study was to evaluate the physiological and biochemical responses of tambaqui fingerlings fed four different levels of silage included in commercial feed with 28% crude protein, over two periods: 45 and 90 days. Each treatment was carried out over three replications, with 10 tambaqui in each 100 L experimental tank. At the end of each established period, blood samples were collected from five animals from each repetition to determine the hematological and biochemical variables. Body weight and total length, hepatosomatic and liposomal indices and hematocrit of specimens fed with diets supplemented with silage did not exhibit significant changes in both assessment period. After 45 days of feeding, the hemoglobin concentration increased when tambaqui were fed a diet including 20% silage. The red blood cell count, mean corpuscular volume and mean corpuscular hemoglobin did not change between treatments in either period. The total protein concentrations increased significantly in the plasma of tambaqui fed with diets with the inclusion of 5 and 10% of silage, evaluated after feeding for 45 days. It was found that the groups which had silage included in their diet did not exhibit significant alterations in the evaluated parameters, and the diet was therefore not consider harmful to the health of tambaqui. Therefore, the use of silage as a feed supplement during tambaqui farming is a sustainable alternative for producers, as it leads to a reduction of impacts of fish and vegetables waste disposal.

“…Sometimes, the inclusion of alternative feeds in forage silages commonly used in ruminant feed can negatively influence the DM content of the mixture. Bonfá et al (2017), evaluating different levels of inclusion (0 to 50%) of pineapple bark to elephant grass silage, observed a reduction in DM content, with values from 33.33 to 21.91%, for treatments with lower and higher level of inclusion of this co-product, respectively.…”

The objective was to evaluate the qualitative and nutritional aspects of elephant grass cv. BRS capiaçu silage with increasing proportions of silk cotton. A completely randomized design was used with five (0, 15, 30, 45, and 60% on natural matter basis) different inclusion proportions of silk cotton to elephant grass silage and four repetitions. Silages were prepared in PVC minisilos and remained ensiled for 42 days. The inclusion of silk cotton resulted in a linear reduction in dry matter (DM), neutral detergent fiber (NDF), acid detergent fiber (ADF), cellulose, and indigestible neutral detergent fiber (iNDF) contents at 0.06, 0.30, 0.23, 0.20, and 0.09 percentage points for each 1% inclusion, respectively. There was an increasing linear effect of crude protein (CP) and total digestible nutrients (TDN), with an increase of 39.32 and 20.89% from the lowest to the highest inclusion of silk cotton to elephant grass cv. BRS capiaçu silage. Values of pH, gas losses (GL), effluent losses (EL), dry matter recovery (DMR), hemicellulose, and lignin were not influenced by the evaluated inclusion levels, showing estimated averages of 3.87, 1, 42%, 11.55kg t-1 natural matter, 97.36%, 19.30%, and 7.20%, respectively. An increasing linear effect was found for fraction a, c, effective degradability (ED) (2% and 5%) dry matter, with an increment of 0.05, 0.0005, and 0.11 percent points, respectively. There was a quadratic effect for fraction b, potential degradability (PD), ED (2%), with minimum points of 23.72%, 50.52%, (at 45% inclusion level) 39.69%, (at 15% inclusion level) respectively. The indigestible fraction (IF) had a quadratic effect with a maximum of 49.48% at the 45% inclusion level. The colonization time (CT) linearly reduced by 0.09 percentage points for each 1% inclusion evaluated. According to the parameters evaluated, the inclusion of up to 60% silk cotton improved nutritional aspects and nutritional value of elephant grass cv. BRS capiaçu silage.

“…O efeito observado com a inclusão deste subproduto sobre o teor de umidade é explicado pelo seu alto conteúdo de MS (90%) e elevada capacidade absortiva (BERNARDES et al, 2013;GOMES et al, 2017). As baixas concentrações de FDN, FDA e LIG na PCP, em comparação ao capim elefante, associadas aos níveis crescentes de inclusão do subproduto, explicam a redução linear dessas variáveis na massa ensilada, o que pode ser atribuído ao efeito de diluição que o aditivo promove nestes componentes da forragem ensilada (SILVA et al, 2016;BONFÁ et al, 2017). Este efeito é benéfico, pois reduz a probabilidade de limitação do consumo da silagem pelos animais via efeito físico causado no rúmen por esses componentes da parede celular vegetal ( VAN SOEST, 1994).…”

Objetivou-se avaliar o efeito da inclusão de níveis crescentes (0, 5, 10, 15 e 20%) de polpa cítrica peletizada (PCP) e melaço em pó (MP) na ensilagem de capim-elefante. O delineamento experimental foi inteiramente casualizado, com 10 tratamentos e cinco repetições. Determinou-se o conteúdo de matéria seca (MS), teores de proteína bruta (PB), fibra em detergente neutro (FDN) e ácido (FDA), lignina (LIG), proteína insolúvel em detergente ácido (PIDA), carboidratos solúveis (CS), potencial hidrogeniônico (pH), nitrogênio amoniacal (N-NH3), perdas por efluentes (PE), perdas por gases (PG) e recuperação da matéria seca (RMS). Foram observados efeitos dos níveis de inclusão da PC e do MP sobre a massa de forragem ensilada. A PCP promoveu aumento de MS e CS, diminuição de FDN, FDA e LIG, e efeito quadrático para a PB. Observou-se redução na PE e PG, resultando em maior RMS com a inclusão deste aditivo. O MP aumentou o teor de MS e diminuiu a FDN, FDA e LIG linearmente. Entretanto, este aditivo promoveu aumento na PE e menor RMS. A PC proporcionou efeitos positivos sobre a silagem e sua inclusão até 10% melhora a qualidade nutricional e evita a redução do teor proteico do material. Por outro lado, o MP apresentou efeitos negativos sobre o teor proteico, perda por EFLU e produção de N.NH3, porém aumentou os teores de MS e CS, bem como as perdas via gás.
