“…Fiorentini et al (2013) demonstrated that the reduction in protozoa concentration leads to a decrease in NH 3 -N concentration in the rumen. In contrast, Kim et al (2007) in sheep and Abuelfatah et al (2016) in goats did not detect any influence of feeding linseed on ruminal pH or concentration of VFA. However, Czerkawski et al (1975) found a decrease in the level of TVFA with 90 g linseed oil /d.…”

This research aims to evaluate the effect of feeding different levels of whole linseed (L); as a lipid source rich in linolenic fatty acid, and full fat soybean (S); as a lipid source rich in linoleic fatty acid; on ruminal and plasma fatty acids profiles, rumen fermentation, and microorganism population. Twenty-four Damascus goats were assigned to 3 dietary treatments; S, S+L and L groups; contained 90% basal diet which consisted of 56.67% Concentrate feed mixture (CFM) and 33.33% Alfalfa hay with either 10% full fat soybean, 5% full fat soybean + 5% whole linseed or 10% whole linseed, respectively. Inclusion of linseed to diets increased (P<0.01) the total volatile fatty acids (TVFA's) and ammonia-nitrogen (NH3-N) (P<0.05) compared to animals fed on soybean diet whereas ruminal pH was not affected by dietary treatments. Significant increases (P<0.01) were detected in the populations of Cellulomonas cellulasea, Bacillus sp., Thermonospora fusca, Acetobacter xylinum, Ruminococcus albus and Clostridium cellulovorans in goats fed on linseed compared to those fed on soybean diets. The populations of R. albus and C. cellulovorans were only affected with the high inclusion of linseed. The number of ciliated sp. (Holotrichs) decreased (P< 0.01) while Entodinomorphs sp. increased (P<0.05) with linseed . There was a significant increase (P<0.05) in the total number of protozoa compared to that of goats which received soybean only. The ruminal and blood plasma fatty acids (FA) profiles of the experimental animals showed considerable modifications. Ruminal stearic acid showed the highest (P<0.01) percentage with linseed feeding while palmitic (P<0.01) and oleic acids (P<0.05) were predominant with soybean feeding. Saturated fatty acids (SFA) detected higher percentage than unsaturated ones on both levels of linseeds. Soybean inclusion increased (P<0.01) percentage of polyunsaturated fatty acids (PUFA) compared to other two groups. In blood plasma; the predominant FA were palmitic, oleic then stearic acids with soybean, either supplied alone or with linseed (S and S+L groups), whereas oleic, palmitic then linoleic acids were predominant with linseed (P<0.01). The percentage of the absorbed UFA with linseed supply was more than SFA in the same group. Plasma total protein, albumin (P<0.01) and urea (P<0.05) were increased by linseed inclusion while createnine (P<0.05) increased with soybean. Linseed inclusion resulted in decreased blood cholesterol (P<0.01), triglycerides (P<0.05), low density lipoprotein (P<0.01) and increased high density lipoprotein (P<0.01) and total antioxidant capacity (P<0.01). Results indicated that linseed inclusion in diets resulted in considerable variations in rumen and plasma FA which indicates health promoting effects. Therefore, fatty acids composition of animal's products resulted in more satisfying and healthful properties for consumer

“…Fibrobacter sp was reduced by treatment at 8 and 20 weeks but no differences were observed for the genera classified as Ruminococcus 1, Butyrivibrio 2 , or Ruminococcaceae NK4A214 group. More recently, Abuelfatah et al (2016) also showed a decrease in R. flavefaciens and F. succinogenes using qPCR and rumen content of goats supplemented with linseed oil in the diet. In accord with our results, Patra and Yu (2015) observed that abundance of F. succinogenes was reduced by garlic oil.…”

Modulating the assembly of the ruminal microbiota might have practical implications in production. We tested how an early-life dietary intervention in lambs influences the diversity and function of the ruminal microbiota during and after the intervention. Microbiota resilience during a repeated dietary intervention was also tested. The treatment, aiming to mitigate enteric methane emissions, combined garlic essential oil and linseed oil. Fifty-six lambs and their dams were allocated to two groups and treatment (T1) or placebo (C1) was drenched from birth until 10 weeks of life. Lambs were weaned at 8 weeks. From 16 to 20 weeks, lambs in each group were divided in two subgroups that received (T1–T2 and C1–T2) or not (T1–C2 and C1–C2) the same treatment. Measurements were done at 8, 14, and 20 weeks. Average daily gain was similar between groups. Methane production was reduced by treatment at 8 and 20 weeks but at 14 weeks it was similar between C1 and T1. Interestingly, early-life treated lambs displayed a numerical increase (P = 0.12) in methane emissions at 20 weeks compared with non-treated lambs. Concentration of VFA was not affected by the intervention at 8 or 14 weeks but a lower concentration was observed in T2 lambs compared with C2 at week 20. Metataxonomics (rRNA gene) revealed differences in archaeal communities between groups of lambs when treatment was applied (weeks 8 and 20); whereas, in accord with methane emissions, these differences disappeared when treatment was discontinued (week 14). Protozoal community structure was not affected by treatment. In contrast, bacterial community structure differed between treated and non-treated lambs during and after the intervention. Rumen and urine LC-MS and NMR metabolomics at week 20 separated C2 from T2 lambs and correlation analysis highlighted interactions between microbes and metabolites, notably that of methylated compounds and Methanomassiliicocceae methanogens. This study demonstrates that a long-term early-life intervention induced modifications in the composition of the rumen bacterial community that persisted after the intervention ceased with little or no effect on archaeal and protozoal communities. However, there was no persistency of the early-life intervention on methanogenesis indicating resilience for this function.

“…These results may be due to the anaerobic fermentation of linseed oil or crushed linseed that increased yielding of VFA's (Kholif et al, 2015) and / or to improvement of ruminal fermentation due to enhancement of cellulolytic bacteria and protozoa activities with linseed (El-Essawy, 2019). In contrast, Kim et al (2007) in sheep, Benchaar et al (2012) in dairy cows and Abuelfatah et al (2016) in goats demonstrated no effect of linseed or linseed oil supplementation on pH and VFA's. These differences in concentrations of TVFA were probably attributed to differences in rumen volume (Chikunya et al, 2004) or to changes in the rumen species composition of microbes in response to inclusion of unsaturated fatty acids in linseed that being toxic to cellulolytic and methanogenic bacteria (Broudiscou et al, 1994).…”

“…Ruminant products contain a variety of FA, particularly polyunsaturated fatty acids (PUFA), which are considered beneficial to human health (Doreau and Ferlay, 2015). The inclusion of linseed as a source of PUFA in the diet has been used to enhance these beneficial FA in animal products (Abuelfatah et al, 2016). Milk fatty acid profile is influenced by dietary fatty acids and ruminal fatty acid T metabolism including lipolysis and biohydrogenation of UFA (Bai et al, 2018).…”

his study aimed to determine the effects of addition of capsulated linseed oil (beads) alone or in combination with vitamin E (α-tocophyrol acetate) as feed additives on animal performance, blood plasma and milk fatty acid (FA) profiles during lactation period. Twenty four Damascus pregnant doses of about 44.5 ± 1.2 kg live body weight were randomly allotted to 3 groups of 8 doses each and assigned to receive one of three experimental diets: control group: where goats were received berseem hay and concentrate feed mixture (50:50) without any additives, (CON), LO group: goats were offered control diet plus 2.5 gm beads/head/day and LO+VE group: goats were offered control diet plus 2.5 gm beads plus 600 IU VE/head/day. The experiment lasted for about 135 days (from mid pregnancy and lasted 60 days post-partum). Results showed that LO beads inclusion strongly increased milk yield, fat (P<0.01), protein, lactose, total solids yield (P<0.05) and milk fat % (P<0.05) compared with control. Blood plasma γ-linolenic acid was positively affected by beads while C20:2ω6 was increased (P<0.05) by beads plus VE. Moreover, beads inclusion reduced lauric (C12:0), myristic (C14:0) and palmitic (C16:0) (P<0.05) acids while increased contents of monounsaturated fatty acids (MUFA) as oleic (C18:1ω9) and polyunsaturated fatty acids (PUFA) as γ-linoleic (C18:3ω3) (P<0.01) and C18:4ω3 (PP<0.05) compared with control milk. As a consequence reduction of the proportions of total SFA (P<0.01), total omega-6 FAs (P<0.05) and omega-6: omega-3 ratio and enhanced the proportions of unsaturated FAs (UFA) and omega-3 FAs (P<0.01) resulted in health quality of goat's milk was improved. In addition, some of blood plasma metabolites were improved with beads where plasma createnine, cholesterol (PP<0.05) and lipase activity (P<0.01) were decreased compared with control animals. Plasma urea (P<0.05), triglycerides (TG) (P<0.01), low density lipoprotein (LDL) (P<0.05), high density lipoprotein (HDL) (P<0.01) and total antioxidant capacity (TAC) (P<0.05) were increased while lipase activity was decreased with VE addition. The inclusion of VE combined with LO beads didn't result in benefits in goat's products. Further in vivo studies should be undertaken to explore suitable level of vitamin E in association with protected form of useful and healthy fatty acids.
