“…In contrast to the present results, Kalaitsidis et al (2021) recorded a significant improvement in milk yield and fat (6.39 vs. 5.95 %) with a mixture of oregano and thyme essential oils. The same tendency was observed with Moringa oleifera essential oil in ewe's milk and fat content (Selmi et al, 2020). In addition, Dorantes-Iturbide et al ( 2022) recorded higher milk production, protein, and lactose content in response to EO supply.…”

“…Also, and in concordance with the present results, Benchaar et al (2008) observed a similar impact of terpenes and EO on the milk and meat fatty acid profiles of dairy cows. However, Selmi et al (2020) recorded a significant effect of Moringa oleifera EO on the FA profile of Sicilo-Sarde ewe milk, whereas Yonjalli et al (2020) showed no change for palmitic acid with tannin extract given that the content of this FA in milk is related to its de novo synthesis, and the stearic acid in milk was significantly affected by tannin extract. Curiously, the supplementation by the same REO largely affected the lamb meat FA profile (Smeti et al, 2018), which could be due to the different used doses of the EO in both studies.…”

Abstract. Milk and dairy products are among daily-consumed foods in most countries. However, milk production and characteristics depend mainly on animal feeding and additives. The basic feeding corresponds to green or conserved forage and concentrate. The aim of this study was to investigate the effects of a conserved oat forage form (hay, H, or silage, S) and rosemary essential oils (REO) as additives on milk production and the fatty acid (FA) profile of Sicilo-Sarde dairy sheep. Forty-eight lactating Sicilo-Sarde ewes were ranked into four homogenous groups. Two groups were fed oat hay (H) and the other group oat silage (S) ad libitum. All the ewes were supplemented with 600 g d−1 of concentrate. Within each form of forage, one group of ewes received a control concentrate, and the other group received the REO concentrate. The milk yield was not affected by REO intake but tended to be higher (P=0.07) for oat hay than for silage (570 vs. 510 mL d−1). The milk protein content was greater for oat silage than hay diets (5.8 vs. 5.3 %), given that the silage form contains more crude protein. In addition, the silage form of forage improved the milk FA profile, with higher C18:3n−3 (0.70 vs. 0.45 %) long-chain FA and polyunsaturated FA (PUFA) n3 proportions and a lower PUFA n-6/n-3 dietetic ratio (P<0.05). The milk of ewes receiving REO contained a lower percentage of vaccenic acid and n−6 PUFA but a higher percentage of n−3 PUFA and consequently lower n6/n3 (2.56) and PUFA / SFA (P<0.05) ratios. In conclusion, REO could be recommended for dairy ewes fed silage to improve the nutritional quality of their milk for human consumption.

“…They showed that milk yield and composition were not significantly changed. Effects of M. oleifera essential oils (0.3 and 0.6 ml/day) supplementation on milk quality and fatty acid profile in dairy sheep were investigated by Selmi et al (2020) and revealed increased milk fat, unchanged protein, decease urea nitrogen, decreased saturated, and decreased unsaturated fatty acid profiles. Mendoza-Taco et al (2022) investigated the impacts of M. oleifera leaf extracts (20 ml) on the physicochemical characteristics of yogurt prepared from sheep milk.…”

referred to as a miracle plant. M. oleifera is a nutritious and medicinal tree species-rich in protein, minerals, and vitamins. M. oleifera is a native plant in Pakistan, India, Bangladesh, and Afghanistan (Fahey, 2005). Supplementation of M. oleifera to animals and humans has received increased attention for its high contents of certain micro and macro-nutrients, which are important in medicine and nutrition for both humans and animals (Oyeyinka and Oyeyinka, 2018;Gupta et al., 2018). Leaves of M. oleifera are reported to contain substantial amounts of vitamins such as A, C, and E (Saini et al., 2014a,b;Hekmat et al., 2015), minerals such as potassium, calcium, magnesium, iron, copper, and manganese (Hekmat et al., 2015), nutrients such as protein, fiber, carotenoids, and tocopherols ( Jongrungruangchok et al., 2010;Moyo et al., 2011; Saini et al., 2014a,b). Some of the Moringa components are known to scavenge free radicals (DanMalam et al., 2001). Sub-

There is an increasing pressure to identify natural feed additives that improve the productivity and health of livestock, without affecting the quality of derived products. The objective of this study was to evaluate the effects of dietary supplementation with essential oils (EOs) on productive performance, rumen parameters, serum metabolites, and quality of products (meat and milk) derived from small ruminants by means of a meta-analysis. Seventy-four peer-reviewed publications were included in the data set. Weighted mean differences (WMD) between the EOs treatments and the control treatment were used to assess the magnitude of effect. Dietary inclusion of EOs increased (p < 0.05) dry matter intake (WMD = 0.021 kg/d), dry matter digestibility (WMD = 14.11 g/kg of DM), daily weight gain (WMD = 0.008 kg/d), and feed conversion ratio (WMD = −0.111). The inclusion of EOs in small ruminants’ diets decreased (p < 0.05) ruminal ammonia nitrogen concentration (WMD = −0.310 mg/dL), total protozoa (WMD = −1.426 × 105/mL), methanogens (WMD = −0.60 × 107/mL), and enteric methane emissions (WMD = −3.93 L/d) and increased ruminal propionate concentration (WMD = 0.726 mol/100 mol, p < 0.001). The serum urea concentration was lower (WMD = −0.688 mg/dL; p = 0.009), but serum catalase (WMD = 0.204 ng/mL), superoxide dismutase (WMD = 0.037 ng/mL), and total antioxidant capacity (WMD = 0.749 U/mL) were higher (p < 0.05) in response to EOs supplementation. In meat, EOs supplementation decreased (p < 0.05) the cooking loss (WMD = −0.617 g/100 g), malondialdehyde content (WMD = −0.029 mg/kg of meat), yellowness (WMD = −0.316), and total viable bacterial count (WMD = −0.780 CFU/g of meat). There was higher (p < 0.05) milk production (WMD = 0.113 kg/d), feed efficiency (WMD = 0.039 kg/kg), protein (WMD = 0.059 g/100 g), and lactose content in the milk (WMD = 0.100 g/100 g), as well as lower somatic cell counts in milk (WMD = −0.910 × 103 cells/mL) in response to EOs supplementation. In conclusion, dietary supplementation with EOs improves productive performance as well as meat and milk quality of small ruminants. In addition, EOs improve antioxidant status in blood serum and rumen fermentation and decrease environmental impact.
