“…The inclusion of spices, especially those containing essential oils, into the diet of ruminants is increasing due to their effects on ruminal fermentation [5, 6] and animal health [10, 24, 25], although there are reduced evidences of spices' effects improving animal performance [26]. In nonruminants, essential oils have been used in a wide scale due to their potential as replacement of antibiotics [27, 28].…”

This experiment aimed to describe the effects of Oregano extract (OE) inclusion into the concentrate fed to dairy heifers on physiological parameters, feeding behavior, intake, and performance. Thirty-two Holstein heifers were randomly distributed into four treatments: C = control, without addition of OE; OE2.5 = 2.5 g; OE5.0 = 5.0 g and OE7.5 = 7.5 g of Oregano extract per heifer/day. Feeding behavior and concentrate intake were assessed individually every day and total dry matter intake (DMI) was determined on the last week of the trial. Compared to control group, OE7.5 reduced by 32% the latency time to approach the feed bunk but increased by 6% the time spent eating the concentrate. Each inclusion of 2.5 grams of OE into the concentrate increased the occurrence of postingestive licking the feed bunk with abundant saliva production 1.2 times (P < 0.01) and tended to increase the occurrence of sneeze events 1.2 times (P < 0.10). No statistical difference was detected between treatments for total DMI, but concentrate DMI was 9% lower for OE7.5 when compared to control and OE2.5. The inclusion of 7.5 grams/day of OE causes small but negative effects in feeding behavior and concentrate intake, without change on total dry matter intake.

“…In sheep and goats, literature on the effects of BPRP on metabolic parameters is quite consistent and concerns, independent for each considered species, especially blood urea decrease [40,93,108,115] are probably associated with the ability of tannins to bind dietary proteins, thereby reducing their degradability at the rumen level, whereas others haemato-parameters are not affected [17,90,91].…”

Recently, the interest in industrial by-products produced at the local level in Mediterranean areas, resulting from fruit and vegetable processes, has increased because of their considerable amounts of bioactive compounds, including polyphenols. In this review, we analyze the most recent scientific results concerning the use of agro-industrial by-products, naturally rich in polyphenols (BPRP), in the diets of small dairy ruminants. Effects on milk production, milk and rumen liquor fatty acid profile, metabolic parameters, and methane production are reviewed. The feed intake and digestibility coefficients were generally depressed by BPRP, even though they were not always reflected in the milk yield. The main observed positive effects of BPRP were on quality of the milk’s FA profile, antioxidant activity in milk and blood, a reduction of rumen ammonia, and, consequently, a reduction of milk and blood urea. The expected beneficial effects of dietary polyphenols in small ruminants were not always observed because of their complex and variable matrices. However, owing to the large quantities of these products available at low prices, the use of BPRB in small ruminant nutrition offers a convenient solution to the valorization of residues arising from agricultural activities, reducing feed costs for farmers and conferring added value to dairy products at the local level, in a sustainable way.

“…In dairy goats, the previous studies have focussed on the effects of the dietary supplementation on the activities of SOD, which showed that the dietary intake positively affected at least partially, some enzymatic and non-enzymatic antioxidant defences of blood and milk (Paraskevakis 2015;Sharifi et al 2017;Tsiplakou et al 2017). However, to date no studies have been published on SOD activity postpartum from goat milk and factors influencing its stability during processing.…”

The aim of the study was to evaluate superoxide dismutase (SOD) activity from partum to 165 days postpartum of Laoshan dairy goat milk and factors affecting the stability of SOD by the autoxidation of pyrogallol method. The results indicated that the SOD activity in colostrum milk was significantly higher than that in mature milk; and it first decreased and then increased for mature milk. There was a significant decline in SOD activity from 98.54 U/mL at 65 C for 30 min treatment to 39.04 U/mL at 100 C for 5 min treatment. It indicated that SOD activity was not entirely lost, and SOD had strong resistance to high temperature. Maximal SOD activity was recorded at pH 6.5 whereas pH greater or lesser than this resulted in decreased activity. In addition, the change of SOD activity under alkaline conditions was less than that under acidic conditions. SOD activities were 105.12 and 67.08 U/mL when the rotational speeds were 45 and 400 g, respectively. Thus, SOD activity decreased as rotational speed increased. The SOD activity increased when the calcium ion concentration was increased, which ranged from 0.2 to 0.6 mg/ mL. SOD activity was significantly increased by 26% in the first 4 days and decreased after 4 days in the process of fermentation. And the activity of SOD for the fifth day decreased 20% over that of the fourth day. These data comprehensively demonstrate a range of conditions change that significantly affects the integrity, activity and function of SOD in goat milk.
