Whole blood transcriptome analysis in ewes fed with hemp seed supplemented diet.

Image result for scientific reports “The hemp plant (Cannabis sativa L.) has a long tradition of being used for many different purposes such as industry, medicine and nutrition. In particular, because hemp seed (HS) is rich in oil protein and considerable amounts of dietary fiber, vitamins and minerals that are particularly suitable also for animal nutrition.

Different studies have evaluated HS on qualitative and quantitative properties of livestock products but as of today, nobody has investigated the molecular pathway behind HS supplementation in farm animals. Thus, in this study, we will report the first RNA sequencing of the whole-blood transcriptome of ewes fed either with a controlled diet (CTR, n = 5) or with a diet supplemented with 5% of hemp seed (HSG, n = 5).

These results indicate that HS supplementation positively affects the energy production pathway in lactating ewes conferring them also more resistance to adverse climatic conditions such as low temperature. Finally, the higher milk lactose content makes the derived dairy products more profitable.”

“In conclusion, in this study, we have assessed the transcriptome signature induced by 5% hemp seed supplemented diet in ewes. The findings suggest that pathways related to energy production were the most affected. In addition, we found that this condition could also be potentially beneficial for adaptation to low temperatures. Moreover, we found a higher content of lactose, which makes the derived dairy products more profitable.”

Nutritional Value of Commercial Protein-Rich Plant Products.

 Plant Foods for Human Nutrition

“The goal of this work was to analyze nutritional value of various minimally processed commercial products of plant protein sources such as faba bean (Vicia faba), lupin (Lupinus angustifolius), rapeseed press cake (Brassica rapa/napus subsp. Oleifera), flaxseed (Linum usitatissimum), oil hemp seed (Cannabis sativa), buckwheat (Fagopyrum esculentum), and quinoa (Chenopodium quinoa). Basic composition and various nutritional components like amino acids, sugars, minerals, and dietary fiber were determined. Nearly all the samples studied could be considered as good sources of essential amino acids, minerals and dietary fiber. The highest content of crude protein (over 30 g/100 g DW) was found in faba bean, blue lupin and rapeseed press cake. The total amount of essential amino acids (EAA) ranged from 25.8 g/16 g N in oil hemp hulls to 41.5 g/16 g N in pearled quinoa. All the samples studied have a nutritionally favorable composition with significant health benefit potential. Processing (dehulling or pearling) affected greatly to the contents of analyzed nutrients.”

Variability in Seed Traits in a Collection of Cannabis sativa L. Genotypes.

Logo of frontplantsci

“Cannabis sativa L. (hemp) is a wind-pollinated annual plant that originated in central Asia. Hemp, naturally, is a dioecious crop, but some monoecious cultivars have been obtained as a result of earlier breeding efforts.

Hemp is an ancient crop that has been cultivated worldwide until the early twentieth century, after which its cultivation declined.

Recently, interest in this multipurpose crop delivering fibers, shives, and seeds, has been renewed by an increasing demand not only for natural fibers but also for the high content and quality of seed protein and oil. Hemp seed contains 25–35% oil, 20–25% protein, 20–30% carbohydrates, 10–15% insoluble fiber, vitamins, and minerals such as phosphorus, potassium, magnesium, sulfur, and calcium.

The increasing demand for vegetable oils and proteins, along with current awareness about their nutritional and functional role in human diet, has made indispensable to characterize new plant sources. In this regard, hemp seed contains all the essential amino acids and fatty acids necessary to maintain healthy human life, and it might be a new good source of nutrients for both humans and livestock.

The principal value of hemp seed oil resides in its fatty acid composition. It contains the two dietary essential fatty acids: linoleic acid (LA; 18:2ω6) and the α-linolenic acid (ALA; 18:3ω3) in the ratio of 2.5–3:1, which has been claimed as ideal for human nutrition.

The seed of Cannabis sativa L. is an expanding source of proteins and oil for both humans and animals.”

Hempseed as a nutritional resource: An overview

“The seed of Cannabis sativa L. has been an important source of nutrition for thousands of years in Old World cultures. Technically a nut, hempseed typically contains over 30% oil and about 25% protein, with considerable amounts of dietary fiber, vitamins and minerals. Hempseed oil is over 80% in polyunsaturated fatty acids (PUFAs), and is an exceptionally rich source of the two essential fatty acids (EFAs) linoleic acid (18:2 omega-6) and alpha-linolenic acid (18:3 omega-3). The omega-6 to omega-3 ratio (n6/n3) in hempseed oil is normally between 2:1 and 3:1, which is considered to be optimal for human health. Hempseed has been used to treat various disorders for thousands of years in traditional oriental medicine.” http://link.springer.com/article/10.1007%2Fs10681-004-4811-6
