“…As with other crop seeds containing high oil percentages, seed viability decreases overtime when stored at high relative humidity (RH) and higher temperatures. Research on kenaf seed storage indicate that seed stored at 8% RH remained fully viable for 5.5 years when stored at either -10 0 C, 0 0 or 10 0 C and fully viable for 5.5 years when stored at -10 0 or 0 0 C at 12% RH" [3].…”

“…However, there has been various results as per the presence /concentration of these factors probably due to varietal differences. The most commonly reported toxic factors in hibiscus seed are the total phenols, tannins and phytic with low levels of tannin, amylase inhibitors, protease inhibitors, phytic acid and gossypol in kenaf seed" [3].…”

Feed supply has remained a major constraint in animal production due to an ever-increasing cost of conventional feedstuff occasioned by the competition between man and animals for cereal grains. There is need to harness the potential of the numerous agro-industrial by-products and the so-called wastes as part of replacing them for expensive feedstuffs. This necessitated for the utilization of kenaf grains and leaf in the diet of micro–livestock. The cost of conventional feedstuffs coupled with high demand for grains for human consumption has stimulated interest in the use of non-conventional, readily available, and cheaper source of feedstuffs. Use of kenaf by-product in other livestock with an impressive result has been recorded without any deleterious effect on the experimental animals. Kenaf is an annual or biennial herbaceous short-lived plant belongs to family malvaceae and is usually considered as a fiber crop, primarily used for rope, twine, coarse cloth and paper. Hence, kenaf grains and leaf could be used as alternative feed resource for micro-livestock.

“…Hibiscus cannabinus (kenaf), an annual herbaceous crop, is famous worldwide for its high-quality fiber, mainly used, for example, in the paper and pulp, textiles, and manufacturing industries. Recently, increased attention has been paid to kenaf shoots utilization in both human food and animal feed production, not only because of their high yields, but also due to their health benefits [5]. The fresh leaves are usually eaten Antioxidants 2024, 13, 532 2 of 11 as vegetables after being cooked, and dried leaves are consumed as tea products or food additives [5][6][7].…”

Apart from being utilized as a commercial fiber at maturity, kenaf shoots have potential as a food and feed source because of their diverse bioactivities. Previous studies have focused on mature stems because of their high biomass, whereas the antioxidant activities (AA) and the destination of AA contributors of kenaf stems and their high-yielding byproduct leaves during the growth stage have rarely been studied. Therefore, we investigated changes in AA and its relative components in kenaf leaves and stems during the four vital growth stages. Higher ABTS radical cation and DPPH radical scavenging abilities and ferric reducing antioxidant power, total phenolic content, total flavonoid content, and total polysaccharide content were observed at all leaf stages and in the late stem stages. Chlorogenic acid (CGA) and kaempferol glycosides, especially kaempferitrin (Kfr), were identified as representative phenolic acids and flavonoids in both kenaf leaves and stems. The content of CGA in both leaves and stems increased corresponding to the plant’s growth stage, whereas kaempferol glycosides were enhanced in leaves but declined in stems. The highest correlation was observed between TPC and AA in all organs. Further evaluation of CGA and Kfr verified that CGA was the predominant contributor to AA, surpassing Kfr. These findings suggest that kenaf leaves increase antioxidant levels as they grow and can be a useful source of stem harvesting byproducts.

Global food insecurity is mostly the result of human-animal competition for food, as well as recent population growth, erratic weather patterns and environmental shocks. Therefore, maximising the production of animal proteins can reduce the competition between demand and consumption. Hence, the current review aimed at outlining the use of hemp on the production, health and reproductive performances of farm animals. The data used in this review were accessed using Google Scholar, Science Direct, ResearchGate and the directory of open-access journals. It was found that industrial hemp, particularly its derivatives such as hemp-seed meal and oil, has gained attention for its potential benefits in animal nutrition and health. The impact of hemp on farm animals, their productivity, health and reproductive performance, is an area of ongoing research. Our findings on the assessment of the nutritional benefits of hemp to livestock have shown hemp to be a great nutritional source to livestock because, hemp-seed cake, a byproduct of hemp oil extraction, is rich in essential and non-essential amino acids, fibre, and healthy fats, including omega-3 and omega-6 fatty acids. When incorporated into animal feed, it can contribute to a balanced diet, potentially improving overall health and productivity. Furthermore, the health benefits may be due to the fatty acid profile in hemp that is known to have positive effects on animal reproduction (optimal fertility and gestation) and health, including anti-inflammatory properties, which could benefit conditions related to inflammation. Additionally, hemp contains compounds such as cannabinoids and terpenes that might offer therapeutic effects, although the effects of these compounds in animals are still being studied. In conclusion, there is limited direct research on hemp’s effect on reproductive performance in farm animals. Hence, more research is necessitated.
