In this study, we assessed the effect of a humic-fatty acid preparation (HFA) used in rabbit feed on certain haematological and biochemical serum parameters (the lipid profile and the Ca, P and Fe contents). A higher RBC, HGB and HCT values were observed in the groups that were given HFA. An increase in Fe concentrations were also noted. The total and LDL cholesterol were lower in the groups which received HFA than in the control group.
Based on the results obtained, it appeared that the inclusion of a new genetically modified type of flaxseed in the diet altered cholesterol metabolism and could reduce the possibility of cardiovascular diseases. Diet enrichment with W92 flaxseed may be a solution to the health issues that are a result of improper diet in humans and animals. © 2016 Society of Chemical Industry.
The objective of the experiments was to demonstrate the influence of low-and high-tannin horse bean on the selected fermentation indicators. The sheep rumen content with the addition of 1, 2 and 5 g of high-and low-tannin horse bean was incubated in vessels of 250 ml volume. A significant increase of ammonia, lactic acid, CO 2 and methane as well as pH decrease in samples with addition of horse bean seed was demonstrated. While comparing high-and low-tannin horse bean varieties, it was observed that in the case of small doses of 1 and 2 g a higher intensity of fermentation takes place in the samples with the addition of high-tannin horse bean. In the case of larger doses of 5 g per sample, a higher intensity of fermentation takes place in the samples with the addition of low-tannin horse-bean. A probable reason for the decrease in the fermentation process intensity in the samples with the addition of 5 g of high-tannin horse bean is a high content of tannins, which reduce fermentation processes. Sheep, fermentation, rumen, horse bean, in vitroA ban on the inclusion of meat-bone meal in the ruminant feeding has resulted in a greater interest of breeders in high-protein plant fodders. These fodders are considerably cheaper than the meat-bone meal and do not involve a risk of infectious diseases. One disadvantage of the fodders is worse protein balance in the amino-acid composition. Horse bean belongs to this type of fodders. Its high nutritive value is associated with a high protein content of high biological value. The horse bean seeds contain approximately 26-30% of the total protein. Globulins are the main protein, which constitutes 55% to 70% of the total protein (Jasińska and Kotecki 1998a;. A disadvantage of the protein contained in the horse bean is the low content of some amino acids, i.e. methionine, cysteine, tryptophan and threonine, whereas its content of lysine is high (Jasińska and Kotecki 1993). The fat content in the horse bean seeds is very low. The horse bean also contains a substantial amount of sugar, including a lot of starch and hemicellulose amounting to approximately 58%. It is also rich in minerals and vitamins Pavlata et al. 2002). There are certain compounds in the horse bean that limit the bioavailability of nutritive components and disturb the functions of glands and internal organs through which they worsen health and reduce animal productivity. The following compounds belong to the above-mentioned ones: tannins, protease inhibitors, lectins, glycosides, phytates, alphaamylase and oligosaccharide inhibitors (Jasińska and Kotecki 1998b).Tannins are intermediate metabolites of the plant synthesis. They are structurally divided into two groups: proanthocyanidins (the condensed tannins) and polyesters of the gallic acid and the hexahydroxydiphenic acid (Hasam 1981). Tannins have the task of protecting the plants against herbivorous animals and those microorganisms that are pathogenic to plants (fungi, bacteria) (Provenza 1995;Scalbert 1991;Hart and Hillis 1972). Tannins have an im...
Alpha-linolenic acid (ALA) is widely regarded as the main beneficial component of flax for the prevention of cardiovascular disease. We evaluated the effect of the transgenic flaxseed W86—which is rich in ALA—on the lipid profile, atherosclerosis progression, and vascular reactivity in hypercholesterolemic rabbits compared to the parental cultivar Linola with a very low ALA content. Rabbits were fed a basal diet (control) or a basal diet supplemented with 1% cholesterol, 1% cholesterol and 10% flaxseed W86, or 1% cholesterol and 10% Linola flaxseed. A high-cholesterol diet resulted in an elevated plasma cholesterol and triglyceride levels compared to the control animals. Aortic sections from rabbits fed Linola had lower deposits of foamy cells than those from rabbits fed W86. A potassium-induced and phenylephrine-induced contractile response was enhanced by a high-cholesterol diet and not influenced by the W86 or Linola flaxseed. Pretreatment of the aortic rings with nitro-L-arginine methyl ester resulted in a concentration-dependent tendency to increase the reaction amplitude in the control and high-cholesterol diet groups but not the flaxseed groups. Linola flaxseed with a low ALA content more effectively reduced the atherosclerosis progression compared with the W86 flaxseed with a high concentration of stable ALA. Aorta contractility studies suggested that flaxseed ameliorated an increased contractility in hypercholesterolemia but had little or no impact on NO synthesis in the vascular wall.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
