Special Issue Information

Dear Colleagues,

Forage and grain crop condensed tannins (CT) and crude protein (CP) could be the key to a number of environmental issues in animal agriculture. The efficient and effective rearing of small ruminant is possible with the use of CT and CP-rich forages and grains because of their digestive support. Using plant-based (natural) CT more effectively to reduce the need for pharmaceutical products in the environment (anthelmintics, microbicides, etc.), reduce methane emissions, increase plant and animal species diversity in cultivated pastures and rangeland, foster greater soil organic matter buildup from plant and fecal material resistant to soil microbial decomposition, etc., could increase the ruminant production in an environmentally sustainable manner. Analyses of the forms of CT and CP in forages and grains would advance the natural healthy rearing practice of ruminants. Climate change is spatially influencing small ruminant farming; therefore, the use of newer technologies such as geospatial- and bio-technology is essential to enhance natural CT and CP-containing forage and crop production systems in the world. The goal of this Special Issue is to compile various advanced research works related to this topic to aid in the achievement of environmentally sustainable forage and crop production optimization. Thus, animal production could be optimized with less dependence on generally less available animal healthcare providers.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Agriculture is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

In the present study, the effects of macro- and microclimatic conditions, month of harvest, and leaf age at harvest on the bromatological composition and polyphenol content of Gymnopodium floribundum leaves were evaluated. Leaves were harvested in December 2017 and 2018 and March, June, and September 2018. At each harvest, three composite samples of mixed-age leaves were collected from 12 trees (four trees for each sample), and the sampling was repeated on day 90 post-harvest to collect 90-day-old leaves. Fresh and dry matter, crude protein, acid and neutral detergent fibers (ADF and NDF, respectively), lignin, total tannins, condensed tannins (CT), total phenols, in vitro dry matter (IVDMD) and organic matter (IVOMD) digestibility, and metabolizable energy (ME) were estimated. Rainfall, relative humidity, and microhumidity were associated with chemical composition. IVDMD, IVOMD, and ME were highest in leaves sampled in March regardless of age (p < 0.001). Water content, ADF, NDF, and lignin were highest in the leaves sampled in September, regardless of age (p < 0.05), suggesting that leaves require more structural support in the rainy season. CT content was highest in September in the mixed-age leaves and in September and December in the 90-day-old leaves (p < 0.05). A high fiber and CT content during the period of rapid leaf growth could deter herbivory. Full article
