“…Another possible explanation is that the amino acid (AA) composition was not balanced for milk protein synthesis. However, Wang et al (2008) reported a good AA profile of hempseed protein, with a significantly higher proportion of essential AA to total AA, compared to soya protein. Concerning the two AA that often are considered to be most limiting for milk production (NRC, 2001), Wang et al (2008) found a higher content of methionine, but a lower content of lysine, in hempseed protein compared to soya protein.…”

In addition, as previously mentioned, the low provision of degradable carbohydrates with high HC inclusion may have restricted synthesis of microbial protein and, therefore, real protein supply to the cows.…”

This study explored the potential for using seed cake from hemp (Cannabis sativa L.) as a protein feed for dairy cows. The aim was to evaluate the effects of increasing the proportion of hempseed cake (HC) in the diet on milk production and milk composition. Forty Swedish Red dairy cows were involved in a 5-week dose-response feeding trial. The cows were allocated randomly to one of four experimental diets containing on average 494 g/kg of grass silage and 506 g/kg of concentrate on a dry matter (DM) basis. Diets containing 0 g (HC0), 143 g (HC14), 233 g (HC23) or 318 g (HC32) HC/kg DM were achieved by replacing an increasing proportion of compound pellets with cold-pressed HC. Increasing the proportion of HC resulted in dietary crude protein (CP) concentrations ranging from 126 for HC0 to 195 g CP/kg DM for HC32. Further effects on the composition of the diet with increasing proportions of HC were higher fat and NDF and lower starch concentrations. There were no linear or quadratic effects on DM intake, but increasing the proportion of HC in the diet resulted in linear increases in fat and NDF intake, as well as CP intake (P , 0.001), and a linear decrease in starch intake (P , 0.001). The proportion of HC had significant quadratic effects on the yields of milk, energy-corrected milk (ECM) and milk protein, fat and lactose. The curvilinear response of all yield parameters indicated maximum production from cows fed diet HC14. Increasing the proportion of HC resulted in linear decreases in both milk protein and milk fat concentration (P 5 0.005 and P 5 0.017, respectively), a linear increase in milk urea (P , 0.001), and a linear decrease in CP efficiency (milk protein/CP intake; P , 0.001). In conclusion, the HC14 diet, corresponding to a dietary CP concentration of 157 g/kg DM, resulted in the maximum yields of milk and ECM by dairy cows in this study.

“…Hemp (Cannabis sativa L.) is a widely cultivated plant with industrial importance for thousands of years by prehistoric humans, especially as an valuable source of food, fiber and medicine [1]. In addition to the medical potential of cannabinoids in the leaves and flowers of the plant itself, hempseed has been utilized in the human diet for thousand of years.…”

The neutrichemical analysis of hempseed from Cheungsam was performed in order to apply hempseed to food industry. Cheungsam hempseed was mainly composed of crude fat (30.52%) and protein (30.02%). The hempseed fat contained about 88% of polyunsaturated fatty acids, and the omega-6 to omega-3 ratio was determined to be approximately 3:1. Hempseed from Cheungsam was rich in essential amino acids. Moreover, hempseed protein from Cheungsam, extracted by acid-base precipitation method, showed free radical scavenging activity. The results suggest that Cheungsam hempseed protein could be utilized as a superior source of protein nutrition.
