“…Lignin is the main chemical component limiting the digestibility of the forage (Cavalcanti et al, 2016). The present work presented significantly negative correlation (r = -0.71) LIG and IVDMD, corroborating with the results of the literature, even if analyzed by different methodologies (Queiroz et al, 2000).…”

The research submitted samples from stems and leaf blades from tree genotypes of Pennisetum purpureum called 93-32-02, 92-70-02, and 91-06-02 (EMBRAPA - Dairy cattle) and elephant grass cv. Napier (reference cultivar) to the chemical, anatomical evaluations, and in vitro dry matter digestibility (IVDMD) measurement. The anatomical characteristics of the stems and leaf blades, the chemical composition, and the IVDMD of these genotypes at 70 days of re-growth were correlated. Concerning IVDMD, the data highlighted differences, and the cultivar Napier presented the smallest value. Digital images obtained by light microscopy from cross-section reveal that all the stem and leaf blade have similar structural organization. Quantitative differences were verified mainly in the stem. The leaves displayed differences only in the mesophyll thickness. The genotypes showed higher potential in the rainy season since they had the largest IVDMD when compared to the cultivar Napier.

“…Grass) e massai (Panicum maximum cv. Massai) destacam-se pela tolerância a condições de estresse hídrico (Cavalcante et al, 2016;Luna et al, 2014), característica de regiões semiáridas. Embora a produção de forragem durante o período seco seja nula, a tolerância atribuída a essas gramíneas permite que o excedente forrageiro no período chuvoso seja conservado e utilizado no período seco, sem que haja a necessidade de replantio do pasto a cada ano.…”

The objective of this study was to evaluate Cynodon species 'Tifton 85' at different hay production phases (harvest, baling, and storage) and different (N) rates. Dehydration of the first crop was carried out in the field, while the second crop was in the shed. Dry matter and protein content increased linearly with the N rates. Dehydration in the shed was not effective for hay production, since dry matter did not reach the desired level of 850 g kg -1. During the hay production period (harvest, baling, and storage), the content of acid detergent fiber of the first crop and the second crop increased by 25.32 and 7.38%, respectively, and that of lignin increased by 21.33 and 32.27%, respectively. Forage digestibility decreased by 4.55%, when dehydration occurred in the field, whereas it decreased by 14.68% when dehydration occurred in the shed, a difference higher than 300% due to the loss of soluble carbohydrates. Overall, the findings of this study indicate that forage dehydration for hay production needs to be carried out in the field under appropriate environmental conditions to prevent nutritional losses. Additionally, dry matter of Tifton 85 increased by 20.40% and protein content increased by 18.65%, which equals 514.27 kg of soybean meal at 100 kg ha -1 of N.
