“…The results of this study closely agreed with the results obtained by Kawai et al [3]. Reynolds [9] reported that a number of studies on cattle have shown that increasing intake reduced DM digestibility, whereas Martin-Rosset et al [6] reported that digestibility in heavy breed nonlactating mares was not affected by the feeding level. Therefore, the digestibility of hay ad libitum in both HH and LH would be similar to those at the maintenance level.…”

Hokkaido native horses (HH) were compared with light half-bred horses (LH) for digestibility and the number of bites and chews when fed non-chopped timothy hay at 90% of the maintenance level in the pen. Apparent digestibility of nutrient and energy in HH were similar to those in LH. The time budget of eating by HH per day was shorter than that by LH (P<0.05, 403.3 vs 557.5 min), while there was no difference between HH and LH in the eating rate. The rate of biting, bite size, chewing rate per a minute and the number of chews per 1 g DM intake in HH were similar to those in LH. Ingestion by HH was indicated to be more efficient than that by LH.

“…The low digestibility levels occurring at higher temperatures are due to increased lignification and the use of the cell wall content through the metabolic processes (Van, 1994). The DM lignification degree and the CP concentration in the forage affect the digestibility of forage (McDonald et al, 2002;Reynolds, 2000). This explains the high herbage IVDMD compared to kermes oak leaves and twigs.…”

Problem statement: The objective of this study was to evaluate the production and nutrition quality of grasslands and kermes oak shrublands in Preveza Prefecture, northwest Greece. Approach: The study involved the collection of herbage and browse samples along a grazing period, from March to October for two consecutive years. In consequence, browse samples were manually separated to leaves and twigs. The three forage components (herbage, kermes oak leaves and twigs) were analyzed for crude protein, Neutral-Detergent Fiber (NDF), Acid-Detergent Fiber (ADF), lignin and In Vitro Dry Matter Digestibility (IVDMD). After the 2 years of observation, we concluded that kermes oak browse, especially the leaves, had CP content adequate to fulfill the nutrient requirements of grazing goats throughout the grazing period. Results: However, this browse is characterized by a very low IVDMD during summer, which may be the result of high lignin content and the presence of anti-nutritional factors such as phenols and tannins. The month of harvest strongly affected the production and nutritive value of forage components, firstly by giving a significant positive correlation among average monthly temperature, production, cell wall contents and secondly, a negative correlation among average monthly rainfall, IVDMD and lignin content. Conclusion: In closure, kermes oak shrublands of the lower zone constitute an important alimentary source providing adequate amounts of browse in order to maintain the nutrient requirements for grazing goats during the summer, when the herbage is not desirable for consumption from sheep and cattle

“…At present many countries adopt large-scale, concentrate-feeding led livestock production like that of the United States, with many potential human health risks due to bacteria, antibiotic-resistant bacteria, prion, and dioxin presence in end products ( Sapkota et al, 2007 ). Despite a rise in concentrate-feeding, forage crops are still used widely as the main source of feed due to its high-yields of DM and energy for low costs ( Reynolds, 2000 ), although usually studies focus on investigating a combination of both especially at various stages of development. For example, studies comparing growth of cattle fed a grass-diet instead of a linseed diet found the end product meat had a healthier fatty acid profile high in beneficial n-3 PUFAs, but the cattle were more slow-growing and thus the meat quality was poorer ( Nuernberg et al, 2005 ).…”

Improving the Yield and Nutritional Quality of Forage Crops

Despite being some of the most important crops globally, there has been limited research on forages when compared with cereals, fruits, and vegetables. This review summarizes the literature highlighting the significance of forage crops, the current improvements and some of future directions for improving yield and nutritional quality. We make the point that the knowledge obtained from model plant and grain crops can be applied to forage crops. The timely development of genomics and bioinformatics together with genome editing techniques offer great scope to improve forage crops. Given the social, environmental and economic importance of forage across the globe and especially in poorer countries, this opportunity has enormous potential to improve food security and political stability.
