“…In this study, lipid supplementation was included in the diet at 3% DM as rumen microbes are generally intolerant to high levels of fat in the diet [28]. This approach was expected to produce some changes in milk FA profiles without detrimental effects on overall productive traits, as has been reported in detail [12,[29][30][31]. This is the first in vivo study to characterize the effect of two different lipid sources, HVO (as saturated fatty acid source) and OO (as unsaturated fatty acid source), on the composition of the rumen bacterial community in dairy cows over a relatively long-term period of 63 days.…”

Dietary lipids increase energy density in dairy cow diets and in some cases can increase beneficial fatty acids (FA) in milk and dairy products. However, the degree of FA saturation may affect the rumen microbiome. The objective of this study was to determine the long-term effects of feeding saturated (hydrogenated vegetable oil; HVO) or unsaturated (olive oil; OO) fatty acid (FA) sources on the rumen microbiome of dairy cows. For 63 days, 15 mid-lactating cows were fed with either a basal diet (no fat supplement), or the basal diet supplemented with 3% dry matter (DM), either HVO or OO. Rumen contents were collected on days 21, 42 and 63 for 16S rRNA gene sequencing using the Illumina MiSeq platform. The results reveal dominance of the phyla Firmicutes (71.5%) and Bacteroidetes (26.2%), and their respective prevalent genera Succiniclasticum (19.4%) and Prevotella (16.6%). Succiniclasticum increased with both treatments at all time points. Prevotella was reduced on day 42 in both diets. Bacterial diversity alpha or beta were not affected by diets. Predicted bacterial functions by CowPI showed changes in energy and protein metabolism. Overall, 3% DM of lipid supplementation over 63 days can be used in dairy cow diets without major impacts on global bacterial community structure.

“…Bypass fat supplementation reported to increase energy consumption and known to have a significanteffect on increasing milk production. Accordingly, many studies have been conducted with the aim of fat as an energy source using prill fat was reported by Kundu et al (2014), Piantoni et al (2015), Chamberlain andDePeters (2017), de Souza et al (2017) and Mathews et al (2016), which stated that there was an increase in milk production and milk fat in dairy cow, but had no effect on body weight gain and dry matter intake of dairy cows.…”

Prill fat is a hydrogenated vegetable oil which contains more than 85% palmitic acid with a high melting point. Due to this reason, it does not melt at rumen temperature and bypass rumen degradation. This study was aimed to determine the optimum level of prill fat (86% palmitic acid) supplementation in dairy ration on fermentation characteristics, feed digestibility, milk production, milk components and milk fatty acid profiles. In vitro analysis used Randomized Block Design with 4 treatments and 4 replications and the in vivo analysis using T-Test. The in vitro result showed prill fat supplementation was significantly affected the total Volatile Fatty Acids (VFA) concentration (p<0.05). The addition of prill fat significantly decreased dry matter and organic matter digestibility (p<0.01), Neutral Detergent Fiber (NDF) and Acid Detergent Fiber (ADF) digestibility (p<0.05), total protozoa biomass (p<0.01) and population of cellulolytic bacteria (p<0.05). Furthermore, supplementation of prill fat in the level of 2% had no effect on pH, ammonia (NH3)N concentration and total rumen bacteria activity. The prill fat treatment at the level of 2% had no effect on dry matter intake, milk component and milk yield on in vivo analysis. In addition, milk yield, milk component and milk fatty acids were elevated after the prill fat treatment. This research concluded, the optimum level of prill fat addition in dairy ration was at the level of 2%. Supplementation of prill fat had no effect on rumen fermentation and fiber digestibility. Prill fat supplementation can be used to augment the milk yield, milk component, fatty acid composition in milk and had no effect on Atherogenicity Index (AI) and Hypocholesterolemic/Hypercholesterolemic (HH).

“…Fat supplementation has become a common strategy to increase the energy density of diets and minimize the effects of negative energy balance (Palmquist and Jenkins, 2017;Bionaz et al, 2020). However, this may reduce DMI, disturb rumen function, and originate fatty acid (FA) isomers that depress milk fat (Chamberlain and DePeters, 2017;de Souza and Lock, 2019;Manriquez et al, 2019). Because FA, namely PUFA, have essential physiologic roles, the beneficial effects of fat supplementation may rely more on FA type than on increased energy intake (Herrera-Camacho et al, 2011).…”

High-yielding dairy cows experience a negative energy balance and inflammatory status during the transition period. Fat supplementation increases diet energy density, and plasma n-3 polyunsaturated fatty acids (PUFA) have been proposed to improve immune function. This study tested the hypothesis that dietary supplementation with a rumen-protected and n-3 PUFA-enriched fat could ameliorate both the energetic deficit and immune status of postpartum high-yielding dairy cows, improving overall health and reproductive efficiency. At 11 d in milk (DIM), cows were randomly allocated to groups (1) n-3 PUFA (n = 29), supplemented with encapsulated linseed oil supplying additional up to 64 g/d (mean 25 ± 4 g/d) of α-linolenic acid (ALA), or (2) control (n = 31), supplemented with hydrogenated palm oil without ALA content. Fat supplements of the n-3 PUFA and control groups were available through an automated, off-parlor feeding system, and intake depended on the cow's feeding behavior. Plasma ALA concentrations were higher in n-3 PUFA than control cows, following a linear relation with supplement ingestion, resulting in a lower n-6/n-3 ratio in plasma. Metabolic parameters (body condition score and glucose and β-hydroxybutyric acid blood concentrations) were unaffected, but milk yield improved with increased intake of fat supplements. Plasma total adiponectin concentrations were negatively correlated with ingestion of n-3 PUFA-enriched fat supplement, following a linear relation with intake. Conception rate to first AI increased with higher intake of both fats, but a decrease of calving-to-conception interval occurred only in n-3 PUFA cows. Postpartum ovarian activity and endometrial inflammatory status at 45 DIM were unaffected. In conclusion, this study evinced a posi-tive linear relation between rumen-protected linseed fat intake and plasma n-3 PUFA concentrations, which modulated adiponectin expression and improved reproductive parameters.
