“…Moreover, Tucker () investigated the effect of essential oil supplementation in broiler diets and found a significant reduction in C. perfringens colonization in gastrointestinal tract (GIT), which could be attributed to bacterial inactivation by digestive enzymes such as trypsin. Patra and Saxena (); da Silva et al () reported that coriander extract had a potent effects against gram‐positive bacteria due to its content of alkaloids and tannins; these bacteria are more sensitive to penetration of the coriander bioactive compounds due to the absence of their outer membrane that present only in gram‐negative bacteria. Delaquis, Stanich, Girard, and &Mazza () concluded that the gastric pH of the broilers in coriander oil supplemented groups was lower than that of broilers in the control group; this would improve the barrier function of the stomach against acid susceptible bacteria, such as coliforms, and favour the growth of acid tolerant bacteria, such as lactic acid bacteria.…”

A total of 480 one‐day‐old Arbor Acres broiler chicks were randomly assigned to four dietary groups, each including six replicates (n = 20/replicate). Broilers in the first group (G1) were fed a basal diet without any additives (control). Broilers in groups 2, 3 and 4 (G2, G3 and G4) were fed a basal diet supplemented with 0.1%, 0.2% and 0.4% coriander (Coriandrum sativum L.) seed powder (CSP) respectively. Feeding trials lasted for 42 days, and after that growth, carcass traits, haematological parameters, gut microbiota and economic efficiency (EE) were evaluated. Final body weight (FBW), total weight gain (TWG), total feed intake (TFI) and red blood cell (RBC) counts of broilers in the G4 and G3 treatment groups were significantly higher (p < .05) compared with broilers in the G1 treatment group. The feed conversion ratio (FCR) was better (p < .05) in the G4 treatment group (1.72) than in the G1 treatment group (1.84). Broilers in CSP treatment groups had significantly higher haemoglobin (Hb) concentrations, packed cell volume (PCV) and platelet counts, and had lower (p < .05) Escherichia coli and Clostridium perfringens counts compared with broilers in the G1 treatment group. Dressing, liver, pancreas, bursa and thymus percentages were higher (p < .05) in broilers in the G4 (70.30, 3.18, 0.31, 0.10 and 0.32% respectively) treatment group, compared with broilers in the control (G1) group (66.57, 2.37, 0.23, 0.04 and 0.21% respectively). Broilers in treatment groups G4 and G3 had lower percentages of abdominal fat and lower total bacterial counts (p < .05) than broilers in treatment groups G2 and G1. The highest economic efficiency (EE) was found in treatment group G4, and EE in this group was 13.06% greater than in the control (G1) group.

“…The 7‐day experimental period was chosen on the basis of the amount of nanocapsule solution (Eudragit L‐100 and PCL) available at that time, with a preliminary focus on antioxidant and anti‐inflammatory effects of curcumin. According to the literature, for seven days the sheep would adapt to the diet (García‐González, Giráldez, Mantecón, González, & López, ; Silva et al, ), proceeding on the 8th of the experiment to make the collections.…”

Low‐dose curcumin‐loaded Eudragit L‐100‐nanocapsules in the diet of dairy sheep increases antioxidant levels and reduces lipid peroxidation in milk

The main objective of this study was to evaluate whether the addition of curcumin‐loaded nanocapsules (prepared and characterized) in the diets of dairy sheep improved milk quality. The nanocapsules were prepared using two polymers: poly‐ε‐caprolactone (PCL) and Eudragit L‐100. The nanocapsules contained 0.25 mg/ml (Nano‐Eudragit L‐100) and 2 mg/ml (Nano‐PCL) of curcumin. Dairy sheep were divided into four groups: A (control), B (30 mg free curcumin/kg concentrate), C (3 mg Nano‐PCL/kg concentrate), and D (3 mg Nano‐Eudragit/kg concentrate). We observed that the number of total leukocytes and serum globulin levels were lower in Group D than in the control (Group A) (p < 0.05). Antioxidant capacity against peroxyl radicals (ACAP) and catalase enzymes was elevated in Group D, with consequently reduced lipid peroxidation (LPO; p < 0.05). In milk, there were no differences in production and composition between groups during the experimental period (p > 0.05); however, ACAP increased and LPO decreased in milk. Practical applications Curcumin is a functional molecule with potent antioxidant, anti‐inflammatory, and antimicrobial actions, used frequently and with medical indications in human food. Free curcumin in sheep diets improves milk quality and increases its shelf life. This study showed that curcumin nanocapsules produced from the Eudragit L‐100 polymer potentiated the anti‐inflammatory and antioxidant actions of dairy sheep when used in the diet daily, at doses 10 times lower than that of free curcumin. These positive effects were reflected in higher total antioxidant capacity and lower lipid peroxidation in milk in sheep‐fed curcumin‐loaded Eudragit L‐100 nanocapsules, generating desirable milk properties. In practice, the use of nanotechnology enhances the beneficial effects of curcumin in milk, possibly creating a nutraceutical food desirable to consumers.

“…However, there are problems related to residues in tissues arising from animals whose production included the use of such antibiotics (Catalan et al, 2012;Pavarini et al, 2012). Silva et al (2016) and Alves Júnior et al (2017) reported that use secondary compounds as phytogenic additives in ruminant nutrition is a promising alternative, as it improves the efficiency of nutrient use by ruminants.…”

Phytogenic additives are organic molecules that also improve ruminal fermentation, turning the supplemented individuals into more productive animals, without damage the population welfare. The objective of this study was to evaluate the effects of mesquite (Prosopis juliflora [Sw.] DC.) extract as phytogenic additive for sheep finished on pasture in the Brazilian Northeast semiarid region. Twenty-four intact lambs (Santa Ines × Dorper F1 crossbred) were used, with an initial body weight of 23.00 ± 1.83 kg. The experiment was carried out in a complete randomized design with four treatments and six replicates. Treatments consisted of four diets: Pasture and no supplementation; grazing pasture and phytogenic additive; pasture, supplementation with Tifton 85 hay, and concentrate; and pasture, phytogenic additive, and supplementation with Tifton 85 hay and concentrate. Prior to supplementation, animals received the phytogenic additive according to treatment. There were nonsignificant differences for nutrient intake and behavior patterns (P > 0.05). However, additive intake derived from mesquite provided an increase (P < 0.05) in digestibility (14.40% total digestible nutrients), N balance (27.12% retained N:ingested N) and performance (8.82% final body weight, 21.81% total weight gain, and 30.81% average daily gain) compared to animals consuming only pasture in rainy period. Thus, the use of mesquite extract as phytogenic additive is recommended for sheep finished on pasture in the Brazilian semiarid region.
