“…Milk CLA was significantly higher in the grazing group, according to the results reported by Dhiman et al [31] in cows, Nudda et al [32] in sheep and goats, D’Urso et al [14], Tudisco et al [15,22,33] and Zicarelli et al [34] in goats. Bergamo et al [35] and Secchiari et al [36] found higher levels of α-linolenic acid in milk from buffaloes housed in a stable but fed fresh forage rather than a total mixed ration.…”

Simple SummaryAn experiment to determine the effect of pasture on stearoyl-CoA desaturase (SCD) and micro-RNA (miRNA) 103 expression was carried out on dairy goats. SCD is involved in determining milk content of conjugated linoleic acids (CLAs) that are considered an important health factor in human nutrition. The alterations of the normal pathway of expression of miRNAs can have consequences on the normal cellular physiology and lead to different types of pathologies. The pasture significantly affected milk fat as well as fatty acid profile in goats, in particular CLAs showed higher levels in grazing animals with potential beneficial effects on human health. The pasture affected only the SCD trend, while that of miRNA 103 was influenced only by the stage of lactation. Due to the increasing interest of consumers for the healthy aspects of foods of animal origin, there is an important ongoing debate in the scientific community concerning those factors affecting milk quality in terms of human health. To our knowledge, this is the first observation of the effects of pasture on miRNA expression in milk from ruminant species.AbstractThe effect of pasture on the stearoyl-CoA desaturase (SCD) and miRNA 103 expression was evaluated on dairy goats divided into two homogeneous groups (G, grazing, and S, stable). Group S was housed in a stall and received alfalfa hay as forage, while group G was led to pasture. The goats of both the groups received the same amount of concentrate. Milk yield did not differ statistically between the groups. Group G showed significantly higher fat (4.10% vs. 2.94%, p < 0.01) and protein percentage (3.43% vs. 3.25%; p < 0.05) than group S. Among milk fatty acids, group S showed significantly higher levels of saturated fatty acids (SFA) and lower values of mono-unsaturated fatty acid (MUFA). The percentages of polyunsaturated fatty acid (PUFA) were not different between groups even if pasture significantly affected the percentages of C18:3 and total omega 3. In group G, total CLAs were twice than in group S (0.646% vs. 0.311%; p < 0.01) mainly due to the differences in CLA cis9 trans 11 (0.623% vs. 0.304%; p < 0.01). Milk total CLA in grazing group was significantly (p < 0.01) higher in August according to the highest value of both linoleic and α-linolenic acids in the pasture. In grazing animals, SCD expression decreased from April to June, increased in July and decreased again in August, while it was almost unvaried along the trial in group S. By contrast, the expression of miRNA 103 showed a similar trend for both groups, decreasing from April to June, increasing in July and falling down in August. To our knowledge, this is the first observation of the effects of pasture on miRNA expression in milk from ruminant species.

“…In our study, the higher molar proportion of acetate and higher acetate to propionate ratio were observed in oat hay and alfalfa hay by adding AOAN, and then this change may contribute to milk fat production by supplying acetate. In animal experiments, the milk fat depression was obtained from Sievert and Shaver [ 17 ] by A. oryzae extract, and Zicarelli et al [ 46 ] by Saccharomyces cerevisiae plus A. oryzae extract. According to Campanile et al [ 47 ], milk fat depression could be due to the increased organic matter digestibility, which allowed higher energy availability for milk yield and reduced the fat mobilization during the first phase of lactation.…”

“…However, the rumen undegraded protein in the feed may be decreased and the effects of AOAN on metabolizable protein including rumen undegraded protein and microprotein is still not clear. Zicarelli et al [ 46 ] observed no differences in terms of milk yield using A. oryzae (20 g/head/d) but a lower percentage of protein content in milk, while the milk protein yield was not calculated according to the numerical increase of milk production. Hence, further investigation is needed to investigate the effects of AOAN supplementation on the metabolizable protein of feedstuff with different protein quality.…”

AOAN may provide enzymes to improve the digestibility of feeds and enhance rumen fermentation. This study determined the effects of AOAN on digestibility, fermentation characteristics, and bacterial composition using in vitro gas recording fermentation system. A total of 30 mg of AOAN was supplemented into 500 mg of TMR, corn silage, oat hay, and alfalfa hay. Fermentation parameters and bacterial communities were determined after 48 h fermentation, and digestibility was determined after 7, 24, 30, and 48 h fermentation. Gas production and dry matter (DM), crude protein (CP), neutral detergent fiber (NDF), and acid detergent fiber (ADF) digestibility were significantly increased by AOAN supplementation at 48 h (p < 0.05), except for digestibility of CP of the TMR (p > 0.05). AOAN increased starch digestibility in corn silage (p < 0.05) and tended to increase that in TMR (0.05 < p < 0.10). AOAN supplementation increased total volatile fatty acid production (p < 0.05). The molar proportions of acetate and acetate to propionate ratio of oat hay and alfalfa hay were increased (p < 0.05). The 16S rRNA analysis revealed that the microbial richness of TMR and oat hay, and microbial evenness of TMR were increased (p < 0.05). AOAN did not affect the α diversity, β diversity, and bacterial composition of the corn silage. The relative abundance of Prevotella was increased and Ruminococcus was decreased in TMR, oat hay, and alfalfa hay. In conclusion, results suggest that AOAN has the potential to improve the utilization of diets differently, including providing enzymes with changing microbiota (TMR, oat hay, and alfalfa hay) or providing enzymes alone (corn silage).

“…Briefly, total fat was extracted according to Folch et al ( 1957 ) and FA transmethylation effected by a base‐catalysed procedure reported by Christie ( 1982 ), modified by Chouinard et al ( 1999 ). The methyl esters were quantified by gas chromatograph (ThermoQuest 8000TOP gas chromatograph, equipped with flame ionization detector; Thermo Electron Corporation) equipped with a CP‐SIL 88 fused silica capillary column [100 m 0.25 mm (internal diameter) with 0.2‐lm film thickness; Varian] set according to Zicarelli et al ( 2016 ). FA peaks were identified by comparing the retention times of commercial standard containing 37 methyl esters of fatty acids (Sigma‐Aldrich).…”

Nutrition plays an important role in determining the metabolic status of the animals, thus also reflecting on animal welfare as well as on livestock performance (Celi et al., 2017). Indeed, in addition to the ration, natural substances can be also used as a supplement in order to modulate the rumen fermentation and to improve milk yield (Arowolo & He, 2018). Goats fed on high-quality and valuable forage provide the production of high-quality milk and dairy products.Natural substances can be also used as nutritional supplements to this purpose, but most of the research has been performed on housed animals (Olagaray & Bradford, 2019). Nevertheless, the influence on the performance can be variable, depending on many factors such as the dosage, diet composition, forage to concentrate
