“…The differences in the response of each cultivar are due to the ability of plants to produce new tillers after cutting (Bortolini et al, 2004). Cedeño et al (2003) in the south of Minas Gerais working with three forage species (Tifton 68, Tifton 85 and Coast cross), highlight the influence of the cut in forage production. For local conditions the Cedeño et al (2003) found out that the best cutting age occurs between 35 and 48 days for grasses.…”

This work aimed to assess the yield of five forage species subjected to nitrogen (N) levels at three different cutting ages. The experiment was carried out in the city of Santa Tereza do Oeste, at IAPAR's (Agronomic Institute of Paraná) experimental field, by applying a randomized complete block design in a factorial scheme 5×4×3, with five species: common black oat (Avena strigosa Schreb cv. Common), IPR 61 oat (Avena strigosa Schreb cv. IPR 61), Triticale Tpolo 981(Xtriticosecale wittmack), IPR 126 White oat (Avena sativa cv. IPR 126) and ryegrass (Lolium multiflorum Lam.); N levels were (0, 30, 60 and 120 kg ha-1); cutting ages were 66, 95 and 116 days after emergence (DAE), with three replications. Dry matter (DM) productivity was assessed in kg ha-1 by cut and total. The common black oat proved to be different from the other forage plants in DM yield, accumulating less quantities of it due to its cycle. The application of nitrogen fertilization to the coverage linearly influenced the ryegrass at 66 DAE and all other species at 116 DAE in a positive manner. Nitrogen did not influence the total accumulation of dry matter of both common black oat and Triticale Tpolo 981.

“…The in vitro dry matter digestibility levels were similar in the cuts performed on 09/07/14 with a 64day interval and in the cut performed on 02/19/14 with an interval of 35 days, and higher than the cut done on 10/08/14 with an interval of 93 days. In evaluating the IVDMD levels of Coastcross, Tifton 68 and Tifton 85, Cedeno, Rocha, Pinto, Muniz and Gomide (2003) found IVDMD values of 60.69%, 65.77% and 60.53%, respectively, at the 42-day cut interval, and values of 47%, 30%, 55.49%, 57.41% at 70 days of cut interval, respectively, for the same forages, demonstrating that the evaluated populations showed good quality with digestibility levels above 55% (Leng, 1990). The lower IVDMD content at the 93-day cut interval is due to changes in the chemical composition of forages with advancing physiological age of the plants (Carvalho & Pires, 2008).…”

A low number of Brachiaria ruziziensis (Syn. Urochloa) cultivars available on the market and a lack of information about its forage potential have made it difficult to expand its cultivated area, and have therefore made it necessary to implement a breeding program for this species. Thus, the objective of this work was to evaluate the nutritional value of ten improved populations of Brachiaria ruziziensis (Syn. Urochloa) and two controls (B. ruziziensis cv. Kennedy and B. brizantha cv. Marandu). The experimental design was a randomized block design with three replications in five sections. The data were submitted to analysis of variance in the subdivided plot in which the primary factors were the populations and the secondary cuts. The Tukey test was used at 5% of significance for the comparison of means. The genotypes used came from the third recurrent selection cycle of Embrapa dairy cattle, originating from the interbreeding of clones which had been identified as superior. The height of the cuts was 10 cm in relation to the ground. The material was cut and weighed in the field to obtain the sample weights to determine the nutritional forage value. After drying, the samples were ground in 1 mm sieves for chemical analyzes and in vitro digestibility. The best CP, ADF and NDF levels observed in IV populations (lower levels of ADF and NDF at 93 days of cut interval and lower NDF contents at 35 and 41 days of cut interval), population VI (higher CP content in the interval of 93 days, lower DM content at 64 and 93 days of cut interval, and lower NDF content at 35 and 64 days of cut interval) showed that these populations can be evaluated under grazing even at an advanced maturation stage. The objective of these selections was to evaluate the nutritional value of improved populations of Brachiaria ruziziensis (Syn. Urochloa) in order to obtain more homogeneous populations for implantation of grazing experiments.

“…In summer, spring, and fall, the more favorable climatic conditions for forage production resulted in higher leaf production, with a higher CP and lower fiber contents. The digestibility of tropical grasses gradually decreases during winter due to increased structural carbohydrates and lignin contents, resulting in lower forage digestibility (Cedeño et al 2003).…”

Production of Jiggs bermudagrass and the impact of quality milk production and quality of Holstein dairy cows under an intermittent grazing system

et al. 2018

Dairy production plays a fundamental role in the Brazilian economy, and high-17 quality forage is necessary for ruminants to produce satisfactory milk levels, so the aim of the 18 present study was to evaluate the production and quality of Jiggs bermudagrass and its effects 19 on the production and quality parameters of milk from Holstein cows under an intermittent 20 grazing system throughout the year. The experiment was conducted in a randomized design 21 with the four seasons as treatments was replicated five times. The season had a significant 22 effect on the production and nutritional parameters of Jiggs bermudagrass with the highest 23 total dry matter production observed during summer followed by spring and fall. The neutral 24 detergent fiber and acid detergent fiber contents were significantly higher in winter. The In 25 vitro dry matter digestibility was significantly higher in summer, spring and fall.
