“…For the grain at the stage of soft mass and harvest maturation of the grains, no differences were observed in the in vitro digestibility of NDF among the cultivars under study. In a study evaluating the nutritional value of green elephant grass harvested at different regrowth ages, Martins et al (2020) found NDF digestibilities of 71.40%, 57.78% and 57.19% for cutting ages of 56, 84 and 112 days, respectively.…”

The objective of the present study was to evaluate the productive performance and nutritional value of forage of wheat and triticale cultivars at different harvest times in the semiarid region of Minas Gerais. Eight wheat cultivars and two triticale cultivars harvested at three stages of plant development were evaluated: Rubberization, grain at the stage of soft mass and harvest maturation. The experimental design adopted was a randomized block in a factorial scheme 10 × 3, with three replicates, 10 cultivars and 3 developmental stages for plant collection. The main agronomic characteristics and nutritional value were evaluated of forage of the cultivars under study. The study demonstrated the potential of wheat and triticale cultivation for forage in the semiarid region of Minas Gerais. The mean dry matter yield of wheat cultivars was 5.90 t ha-1, 7.85 t ha-1 and 7.98 t ha-1 and triticale 6.47 t ha-1, 9.97 t ha-1 and 10.5 t ha-1 for the rubber harvesting stages, grain at the stage of soft mass and harvest maturation, respectively. For the average crude protein content, the wheat cultivars showed 15.07%, 9.13%, 10.60% and the triticale cultivars showed 14.4%, 9.31% and 10.05% for the harvest stages of rubber formation, grain at the stage of soft mass and harvest maturation, respectively. When evaluating the average levels of total digestible nutrients, the wheat and triticale cultivars showed an average of 48.90% and 48.67% in the rubber harvesting stage and 42.68% and 49.60% in the grain in the mass stage suave and 44.43% and 42.90% at harvest maturation. The highest yield of digestible dry matter was observed with the cultivars harvested at the grain stage at the soft mass stage. Triticale IPR 111 and Wheat IPR PANATY had greater productive potential and better nutritional quality for use as forage.

“…Among the forage species recommended for the ensiling process, elephant grass (Pennisetum purpureum) stands out, as it is easy to implement pasture, large number of varieties, high forage yield, reasonable nutritional quality and good palatability. It should be note that the chemical-bromatological composition of elephant grass may vary according to cultivar, cultural practices and management (Carvalho, 1985;Vilela, 1997;Narciso Sobrinho, 1998;Hertentains et al, 2005;Magalhães et al, 2007;Mfoukou-Ntsakala et al, 2008;Magalhães et al, 2009;Cevallos et al, 2016;Kamaruddin et al, 2018;Rodrigues et al, 2018;Rosa et al, 2019;Martins et al, 2020).…”

The objective of this study was to evaluate the chemical-bromatological composition of elephant grass (EG) silages with the addition of acerola by-product (ABP). The experimental design was completely randomized, with five treatments: Treatment 1 = 100% EG; Treatment 2 = 94% EG + 06% ABP; Treatment 3 = 88% EG + 12% ABP; Treatment 4 = 82% EG + 18% ABP and Treatment 5 = 76% EG + 24% ABP, with four replications (silos). EG and ABP were mixed at the time of ensiling. The silos were open at 42 days and samples were collect for chemical analysis. The addition of up to 24% of ABP in EG silage significantly (P<.05) increases the pH, dry matter (DM) and crude protein levels, thus providing fermentations within desirable standards. The estimated dry matter intake, neutral detergent fiber (NDF), ash and ethereal extract of EG silage was not influenced by ABP. Total digestible nutrients, total carbohydrates, hemicellulose and estimated DM digestibility decreased linearly. The high levels of NDF and acid detergent fiber of the ABP compromise the DM digestibility, reducing the nutritional value of the silages.
