“…Diets, HSC, SBM, and ration formulations all have chemical profiles that are similar to those reported by Semwogerere et al ( 2022 , 2023a , 2023b ) (Tables 1 and 2 ). In summary, the inclusion of HSC in diets resulted in a linear increase (P ≤ 0.05) in DM, EE and ash, fiber (i.e., NDF, ADF and lignin) and phenolic components (i.e., total phenols and tannins) and linear decrease (P ≤ 0.05) in CP, starch, metabolizable energy and non-fibrous carbohydrates.…”

“…Hempseed cake (HSC) has the highest potential among the hemp by-products to be used as animal feedstuff owing to its high crude protein (CP; 341 ± 50.4 g/kg dry matter; DM), neutral detergent fiber (NDF; 395 ± 40.7 g/kg DM) and ether extract (EE; 116 ± 15.5 g/kg DM) with the NDF and EE almost triple that of soybean meal (SBM; NDF: 125 ± 17.6; EE: 40 ± 15.9; g/kg DM) (Pojić et al 2014 ; Paula et al 2018 ; Leonard et al 2020 ; Semwogerere et al 2023a ). Apart from having high protein and energy contents, HSC contains bioactive compounds such as cannabinoids, tocopherols and polyunsaturated fatty acids (PUFA) (Leonard et al 2020 ; Sainz Martinez et al 2023 ; Semwogerere et al 2023b ).…”

Globally, the price of soybean meal, the most common proteinaceous ingredient in livestock diets, has become highly expensive prompting a search for alternative ingredients. Hemp seed cake is a promising alternative but could be limited by its high neutral detergent fiber and ether extract contents which impede nutrient intake and digestibility. However, some ruminant species such as goats have superior ability to digest high fiber and ether extract diets. Thus, the current research evaluated nutrient intake and digestibility, rumen fermentation, and microbial protein synthesis of goats fed hempseed cake as a substitute for soybean meal in finisher diets. A total of 25 Kalahari Red castrates (27 ± 3 kg, 4–5 months old) were assigned to five dietary treatments (5 goats/ diet) in a completely randomized design. A maize-lucerne-based finishing diet was formulated with hempseed cake substituting soybean meal as the primary protein ingredient at 0, 25, 50, 75, or 100 g/kg dry matter. Ether extract intake exhibited a positive linear trend (P ≤ 0.05) while crude protein intake and microbial nitrogen supply exhibited a negative linear trend (P ≤ 0.05) with dietary inclusion of hempseed cake. However, feeding hempseed cake did not influence (P > 0.05) apparent nutrient digestibility, rumen fermentation parameters and nitrogen use efficiency. In conclusion, the substitution of soybean meal for hempseed cake decreased crude protein intake and microbial nitrogen supply in goat finisher diets without compromising nutrient digestibility and nitrogen use efficiency. The study recommends partial or full replacement of soybean meal with hempseed cake in goat finisher diets.

“…Cannabinoids and tocopherols were determined as described in a companion paper by Semwogerere et al (2023). For bioactive minerals, ve grams of feed, liver, meat, urine and fecal samples were weighed into microwave digester Te on vessels, followed by the addition of 6 mL ultra-pure HNO 3 + 1 mL H 2 O 2 , prior to digestion using MARS microwave digester (CEM, Germany).…”

Hempseeds are rich in bioactive phytochemicals, yet little is known about their bioavailability in tissues and excreta of animals fed hemp seed cake. The study evaluated the bioactive phytochemicals and their antioxidant activity in blood, liver, meat, feces and urine from goats fed finishing diets containing graded inclusions of hempseed cake (HSC). Twenty-five wether goats (27 ± 3 kg) of 4-5 months were randomly allocated to five experimental diets containing increasing levels of HSC (0, 25, 50, 75, 100 g/kg DM) substituted for soybean meal (SBM) as the main protein source. Goats were adapted for 21 days, and blood, fecal and urine samples collected on day 28. The liver and right longissimus thoracis et lumborum were respectively collected 60 min and 24 h after slaughter. Linear increases (P ≤ 0.05) in blood, liver and urine magnesium, fecal manganese, and fecal copper were observed with increasing HSC inclusion in the diet. Liver and fecal selenium exhibited a decreasing linear trend (P ≤ 0.05) with HSC increment in diets. Diet did not affect (P > 0.05) meat and urine mineral contents, except urine magnesium. The 2,2-diphenyl-1-picrylhydrazyl (DPPH), and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid; ABTS) of blood, liver, and meat linearly increased (P ≤ 0.05) with dietary inclusion of HSC. Blood and liver ferric reducing antioxidant power (FRAP) quadratically increased (P ≤ 0.05) with HSC inclusion reaching a maximum at 50 g/kg DM. Current results suggest that inclusion of HSC up to 100 g/kg substituting SBM in goat diets can improve bioavailability of bioactive phytochemicals in blood, liver, and meat.

Hempseeds are rich in bioactive phytochemicals, yet little is known about their bioavailability in tissues and excreta of animals fed hemp seed cake. The study evaluated the bioactive phytochemicals and their antioxidant activity in the blood, liver, meat, feces, and urine from goats fed finishing diets containing graded inclusions of hempseed cake (HSC). Twenty-five wether goats (26.8 ± 2.9 kg) of 4–5 months were randomly allocated to five experimental diets containing increasing levels of HSC (0, 25, 50, 75, 100 g/kg DM) substituted for soybean meal (SBM) as the main protein source. Goats were allowed for period of 21 days for adaptation, and blood, fecal, and urine samples were collected on the 28th day of the experiment. The liver and right longissimus thoracis et lumborum were respectively collected at 60 min and 24 h after slaughter. Linear increases (P ≤ 0.05) in blood, liver, and urine magnesium; fecal manganese; and fecal copper were observed with increasing HSC inclusion in the diet. Liver and fecal selenium exhibited a decreasing linear trend (P ≤ 0.05) with HSC increment in diets. Diet did not affect (P > 0.05) meat and urine mineral contents, except urine magnesium.

Current results suggest that inclusion of HSC up to 100 g/kg substituting SBM in goat diets can improve bioavailability of bioactive phytochemicals in the blood, liver, and meat.
