“…Tzamaloukas et al [ 25 ] reported a tendency for a seasonal effect in the LA/ALA ratio in bulk-tank goat milk collected from conventional and organic farms. The LA/ALA ratio values were within the reported range (3.81–7.44) for goat milk produced from ewes fed concentrates [ 42 , 43 ] but remarkably lower than the values (10.37–11.37) reported by Tzamaloukas et al [ 25 ] for goat milk either conventionally or organically produced throughout the year. Lower LA/ALA ratio values are preferable because the LA/ALA ratio is related to higher levels of n −3 fatty acids that are beneficial for health, such as α-linolenic acid (C18:3 n −3), which is the predominant acid of the n −3 lipid class in goat milk.…”

An increased consumer interest in goat milk has been registered in recent years due to its health-related benefits. This study aimed to investigate the effects of production systems and seasons on fatty-acid composition and nutritional indices for the healthy fat consumption of retail goat milk. The study lasted one year, and milk samples (n = 160) from 14 brands (10 conventional and 4 organic) were collected on a monthly basis. Organic milk had a marginally lower fat and protein content compared with conventionally produced milk according to the declared chemical composition. The production system did not significantly affect milk fatty-acid composition and its nutritional value, indicating that there were no major differences in the feeding strategies between conventionally and organically raised ewes. Seasonal effects were observed in the fatty-acid profile and the nutritional indices. Lower content of saturated fatty acids (SFAs), hypocholesterolemic/hypercholesterolemic ratio (h/H) and linoleic acid/α-linolenic acid (LA/ALA) ratio values were observed in summer. Retail goat milk had a desirable nutritional value, irrespective of production system and season, due to the following characteristics: low atherogenic index (AI) and LA/ALA ratio values, and high h/H ratio, desirable fatty acid (DFA) values and health-promoting index values. In conclusion, neither production nor season significantly impacted the fatty-acid composition and the fat-consumption nutritional indices of retail goat milk produced in Greece.

“…This is due to its comparable composition of nutrients, speci cally crude protein (34 ± 2.1 g/kg DM) to SBM (39.2 ± 5.4 g/kg DM) (Abrahamsen et al, 2021;Bailoni et al, 2021). Numerous studies have reported similar or improved performance of ruminants fed HSC relative to SBM (Turner et al, 2012; Abrahamsen et al, 2021;Šalavardić et al, 2021). More so, hempseed contains several bioactive phytochemicals with the major ones being cannabinoids, tocopherols, terpenes, polyphenols and microminerals (Andre et al, 2016;Small, 2017).…”

“…This is largely driven by the legalization of hemp cultivation (Russo, 2019;Leonard et al, 2020) and escalating prices for cereal and legume grains including soybean meal (SBM), which is the primary protein feedstuff in ruminant diets (Klir et al, 2019;Šalavardić et al, 2021). Among the hemp byproducts, hempseed cake (HSC) has been the most utilized in livestock diets (Antunović et al, 2020;Bailoni et al, 2021;Šalavardić et al, 2021). This is due to its comparable composition of nutrients, speci cally crude protein (34 ± 2.1 g/kg DM) to SBM (39.2 ± 5.4 g/kg DM) (Abrahamsen et al, 2021;Bailoni et al, 2021).…”

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.

“…In recent years, there has been growing interest in exploring the feasibility of feeding industrial hempseed and its by-products to cattle [7][8][9], sheep [10], goats [11] pigs [12], and poultry [13]. The renewed interest in using industrial hemp by-products as alternative feed ingredients is due to 1) the legalization of industrial hemp cultivation in many parts of the world; and 2) the increasing global demand for industrial hemp from the food and beverage, personal care, and animal care industries.…”

A growing number of studies have investigated the feasibility of utilizing hemp by-products as livestock feedstuffs; however, their impact on livestock microbiomes remains unexplored. Here, we evaluated the effects of feeding hempseed cake on the gastrointestinal, respiratory, and reproductive microbiota in beef heifers. Angus-crossbred heifers (19-months old) were fed a corn-based finishing diet containing 20% hempseed cake as a substitute for 20% corn dried distillers’ grains with solubles (DM basis; Control; n = 16/group) for 111 days until slaughter. Ruminal fluid and deep nasopharyngeal swabs (days 0, 7, 42, 70 and 98), and vaginal and uterine swabs (at slaughter) were collected, and the microbiota assessed using 16S rRNA gene sequencing. Diet affected the community structure of the ruminal (d7– 98; 0.06 ≤ R2 ≤ 0.12; P < 0.05), nasopharyngeal (d 98; R2 = 0.18; P < 0.001), and vaginal (R2 = 0.06; P < 0.01) microbiota. Heifers fed hempseed cake had increased microbial diversity in the rumen, reduced microbial richness in the vagina, and greater microbial diversity and richness in the uterus. In addition to the distinct microbial communities in the rumen, nasopharynx, vagina and uterus, we identified 28 core taxa that were shared (≥ 60% of all samples) across these sampling locations. Feeding hempseed cake appeared to alter the bovine gut, respiratory and reproductive microbiota. Our findings also highlight the need for research evaluating the impact of hemp-associated food and personal care products on the human microbiome.
