“…The interest to this plant is mainly oriented to produce seed for human and animal nutrition, shives for construction (green building) and animal bedding, and fibre for textile and paper industry (“industrial hemp”). In dairy ruminant nutrition, hempseed and derivatives (oil, cake and meal) can be used as a supplement in feed mainly as sources of essential fatty acids and essential amino acids [ 12 ].…”

Recently, hemp (Cannabis Sativa L.) was rediscovery as a plant that offers a wide variety of applications (textile, pharmaceuticals, construction, etc.), including also the use in animal and human nutrition. The inclusion of whole seeds and co-products obtained by processing of seeds (cake, meal, and oil) in the diets of farm animals can allow the transfer of bioactive substances to human food. Few publications are available on the use of hemp in dairy ruminants but some authors reported a positive effect on the fatty acids profile of milk and cheese with an increase of n-3 fatty acids and c9,t11 conjugated linoleic acid. The protein content, amino acids profile, and rumen undegradable protein (RUP) of hempseed and co-products of hemp appear interesting and suitable for ruminant nutrition. Negative effects of anti-nutritional factors (i.e., phytate) are not observed. However, the researches on the effects of the use of hempseed and co-products in diets for dairy ruminants do not allow to suggest optimal levels of inclusion. In addition, no data are published on the use of whole or part of the hemp plant as forage, as another possibility to use the hemp in the perspective of the circular economy.

“…In contrast to linseed, hempseed supplementation offers a well-balanced linoleic acid/linolenic acid ratio of about 3:1 and contains both stearidonic acid (C18:4 n-3) and γ-linolenic acid (C18:3 n-6) [13]. The supplementation of ruminants' diet with hempseed and hempseed oil has been tested and a higher milk fat content with larger proportions of linoleic acid, rumenic acid (C18:2 cis-9, trans-11), and linolenic acid were observed in both sheep [14] and goats [15].…”

NMR Lipid Profile of Milk from Alpine Goats with Supplemented Hempseed and Linseed Diets

et al. 2020

The supplementation of goat diets with natural products to obtain milk with nutraceutical components is a common practice. In these last years, the influence of supplementation of specifically designed diets has been studied with different analytical tools in order to explore possible beneficial effects in human consumption of animal milk and milk-derived products. In this study, the lipid fraction of milk from Alpine goats undergoing different dietary regimens was studied by 1H-NMR spectroscopy. Alpine goats were fed with linseed or hempseed supplements, and after 14 weeks of treatment, milk was collected and analyzed. Results showed that feeding diets supplemented with seeds positively affected the fatty acid composition with a pronounced increase in unsaturated fatty acids for both diets compared to a control diet. Specifically, linolenic acid content was more than doubled for linseed diet compared with the hempseed and control groups, while linoleic acid greatly increased only upon hempseed supplementation. However, a number of conjugated linoleic acid (CLA) isomers and higher levels of fatty acids with trans configuration were found in supplemented diets, particularly in the linseed diet.

“…Hemp seeds and hempseed cake contain tocopherols, especially γ-tocopherol (60.85 and 33.72 mg/100g DM, respectively), which increase oxidative stability of sheep milk (Mierlita, 2018). Klir et al (2019) indicated the possibility of using hempseed cake in animal diets without causing major changes in production and possible increase of desirable fatty acids in animal products.…”

The aim of this study was to investigate the effect of hempseed cake on production traits, metabolic profile and antioxidant status of lambs. The research was conducted on 20 Merinolandschaf lambs of similar live body weight (24.03 kg ± 2.22 and 24.06 ± 1.84 kg in control and experimental group, respectively). The experiment started after the weaning of lambs at their average age of 70 days. Lambs were divided by gender (50% male: 50% female) and then allocated in two groups. The research lasted for 30 days during the fattening period. Lambs in the control group were fed with feed mixtures, where main protein source was soybean meal and extruded soybean (SB), while lambs in the experimental group were fed feed mixtures in which soybean was replaced by hempseed cake (HSC) at 12% of dry matter. Higher values of daily weight gain (P<0.05) compared to SB lambs were observed from the 15th to 30th day. HSC lambs showed no significant differences in hematology and biochemical blood parameters, except for lower (P<0.001) urea concentrations on days 15th and 30th, as well as higher (P<0.05) Mg concentrations in serum on the 30th day. Hempseed cake in lambs′ diets did not influence (P>0.05) activity of the enzymes, like AST, ALT, ALP, GGT and CK, as well as SOD and GPx enzymes, thus not affecting the antioxidant status of lambs′ blood. Concentrations of DHA and n-3 fatty acids were higher (P<0.05) in HSC group than in SB group. The present study confirmed that the inclusion of HSC as soybean replacement up to 12% in the lambs’ diet is justified when considering production traits, metabolic profile and antioxidant status of Merinolandschaf lambs.
