Effect of hempseed(Cannabis sativaL.) on performance, egg traits and blood biochemical parameters and antioxidant activity in laying Japanese Quail (Coturnix coturnix japonica)

Abstract

1. This study was conducted to determine the effects of hempseed (HS) on performance, egg traits, serum lipid profile and antioxidant activity in Japanese quail (Coturnix coturnix japonica). 2. A total of 120 eight-week-old laying quail were divided into 4 experimental groups with 10 replicates. The treatments were as follows: (1) control diet (C, no HS in the diet); (2) 5% HS in the diet (HS5); (3) 10% HS in the diet (HS10); and (4) 20% HS in the diet (HS20). The quail were fed the experimental diets from 8 to 14 weeks of age. 3. There was no significant difference in body weight, feed intake and feed conversion ratio of the birds overall in the experiment. The egg production was not influenced by the HS contents in the diet; however the HS10 diet increased egg weight and egg-specific gravity. The carcass traits were not affected by the HS contents. 4. The serum triglyceride, cholesterol and the high density lipoprotein were not significantly altered; however, low density lipoprotein (LDL) concentration in HS-supplemented groups were lower than that of the C group. 5. The malondialdehyde, superoxide dismutase, catalase and nitrogen oxide concentrations were not significantly affected, but in the HS10 and HS20, glutathione peroxidase (GSH-Px) concentration was higher than in the C and HS5 groups. 6. The omega-3 fatty acid content of eggs increased linearly with increasing dietary HS content in the diet. 7. In conclusion, HS could be a potential feed and health benefit as a natural antioxidant in relation to decreasing serum LDL and increasing GSH-Px concentration in the liver of laying quail.

Effect of dietary supplementation of hemp seed (Cannabis sativa L.) on meat quality and egg fatty acid composition of Japanese quail (Coturnix coturnix japonica)

“…FA was identified by comparison of retention times to known standards. The results were expressed as g FA/100 g total FAs (%) (Konca et al., ).…”

Alternations in Cholesterol and Fatty Acids Composition in Egg Yolk of Rhode Island Red x Fyoumi Hens Fed with Hemp Seeds (Cannabis sativaL.)

“…Previously Khan et al [7] reported that supplementation of HS at the rate of 20% improved the weight gain in broiler. Konca et al [13] found no effect of adding HS on the body weight, feed intake, and feed conversion ratio; however, serum low density lipoprotein (LDL) decreased in the Japanese quails.…”

“…Konca et al [13] further reported that omega-3 fatty acid inhibits tumor and cancer growth, lowers cholesterol, helps normal blood pressure, and increases fats digestion. It also has anti-inflammatory characteristics and thus helps arthritis patients [14].…”

“…It also contains carotene and up to 35% oil [8][9][10]. HS contains a small quantity of delta-9-tetrahydrocannabinol (THC), a psychoactive compound [11] which provokes appetite [12,13]. HS oil contains 80% essential fatty acids (EFAs) including stearidonic acid, alpha-linolenic acid, gamma-linolenic acid, and linoleic acid.…”

The effect of flax seeds addition in nutrition of quails on the quality of carcass and meat

“…By using flax seeds or flax oil, as well as other forms of fat in animal nutrition, we can positively affect their productivity, improve the nutritional value of meat or modify the fatty acid profile in the fat of animal products, improving their quality [Horoszewicz et al 2010, Konca et al 2014, Kawęcka et al 2016, Makała 2019.…”
