“…(2) shows the results of the statistical analysis of body weight in ewes in the last six weeks before birth until weaning, indicating that there were no significant differences between the three groups. The results of the study agreed with [22] in an experiment when 15 female goats were fed on Turmeric in ratios of (0, 2, 5) gm / kg dry matter, with results [23] in a study on 36 Holstein cows fed on medicinal plants, including turmeric, and the reason may be attributed to the fact that the diets used provided the needs of all ewes for the purpose of sustainability and production The use of turmeric did not show any effect on body weight [24].…”

In this study, 18 pregnant Awassi ewes were used to study the effect of different levels of turmeric on physiological performance. The ewes were divided into three equal groups. The three groups were fed 6 weeks before birth until weaning on a basic diet containing protein 14.46 and energy 2583 kcal/kg. The first group was fed without an additive (control), While turmeric powder was added to feed the second and third groups at the rate of 5 and 10 g/day/ewe, respectively. The results indicated that the use of turmeric powder led to a significant increase in the weights of lambs during the eighth, tenth and twelfth weeks in favor of the second treatment, and there was a significant increase in glucose concentration in the first month. And the third in the second group, and in the concentration of cholesterol, a significant improvement was observed in the second and third groups in the first month, and a significant improvement in the second group only in the second month, while the third group had a significant improvement in the third month only. In triglycerides, a significant improvement was observed in the first month only in the second and third groups. In total protein, a significant increase was observed in the first month only in the third group. In the ALT enzyme, a significant improvement was observed in the second group for the second month, while in the third month a significant improvement was seen in the AST and ALT enzymes of the third group. As for blood images, a significant superiority was observed in the number of white blood cells in the second treatment, while no significant differences were found between the treatments in the number of red blood cells, hemoglobin, and packed blood cells, while turmeric powder did not affect the average weights of ewes.

“…In pigs, HPT is one of the main proteins from APR and synthesised by the liver (HULTÉN et al, 2003). A lower concentration of HPT in tannin-supplemented - -------------------------Treatments------------------------------SEM------------------------P-value------------------ ------------------------------------------------------------------- ------------------------------------------------------------------ ------------------------------------------------------------------ --------------------------------------------------------------------- ------------------------------------------------------------------- simple diets indicates a reduction in inflammatory processes, which has also been found in ruminants (RODRIGUES et al, 2019). According to previous findings, HPT is a biomarker for inflammatory processes (ECKERSALL, 2000), and phytogenic ingredients help regulate inflammatory and acutephase responses (YANG et al, 2010).…”

This study evaluated the effect of black wattle (Acacia mearnsii) condensed tannin extract in simple and complex diets for weaned piglets on performance, faecal consistency and serum haptoglobin concentrations. Eighty-eight female and castrated male piglets were used, weaned at 28 ± 3 days old, with an initial body weight of 8.02 ± 1.21 kg, housed in same-sex pairs and distributed in four treatments in a 2 x 2 factorial experiment in a randomised complete block design. The experimental treatments were simple diet (SD), simple diet + tannin (SD+T), complex diet (CD) and complex diet + tannin (CD+T). The simple diets contained lower concentrations of dairy ingredients, inclusion of barley and no addition of zinc oxide, palatant, acidifier and yeast. The diets with tannin were supplemented with 1,850 mg kg-1 of black wattle condensed tannin extract. The feed programme consisted of three diets: Pre-starter I (0-7 days), Pre-starter II (8-21 days) and Starter (22-28 days). Feed and water were available ad libitum. Body weight and feed intake were measured weekly to calculate the average daily feed intake, daily weight gain and feed conversion ratio. The faecal consistency score was measured daily to calculate the diarrhoea occurrence percentage. Blood samples for serum haptoglobin concentration were collected at 7 and 14 days after weaning. The addition of condensed tannin had no effect (P > 0.05) on evaluated performance variables for weaned piglets. The diet type also did not affect the piglets’ performance (P > 0.05). The inclusion of black wattle (Acacia mearnsii) condensed tannin does not affect piglet performance, reduces the incidence of diarrhoea in the first week after weaning and decreases the haptoglobin inflammatory response.

“…In dairy cows, thyme essential oil supplementation via esophageal tube decreased the standard plate count, while no differences were observed in the raw milk composition [ 61 ]. Moreover, although Rodrigues et al [ 62 ] observed an increase in milk yield after dietary supplementation with a phytogenic mix, no effect on milk composition and incidence of clinical mastitis was observed in dairy cows.…”

Due to the limitations in the use of antibiotic agents, researchers are constantly seeking natural bioactive compounds that could benefit udder health status but also milk quality characteristics in dairy animals. The aim of the current study was therefore to examine the effects of a standardized mixture of plant bioactive components (MPBC) originated from thyme, anise and olive on milk yield, composition, oxidative stability and somatic cell count in dairy ewes. Thirty-six ewes approximately 75 days after parturition were randomly allocated into three experimental treatments, which were provided with three diets: control (C); without the addition of the mixture, B1; supplemented with MPBC at 0.05% and B2; supplemented with rumen protected MPBC at 0.025%. The duration of the experiment was 11 weeks, and milk production was weekly recorded, while individual milk samples for the determination of composition, oxidative stability, somatic cell count (SCC), pH and electric conductivity were collected. Every two weeks, macrophage, lymphocyte, and polymorphonuclear leukocyte counts were also determined in individual milk samples. It was observed that milk yield was the greatest in the B2 group, with significant differences within the seventh and ninth week (p < 0.05), whereas no significant differences were found for milk composition, with the exception of the seventh week, when protein, lactose and non-fat solid levels were lower in MPBC groups (p < 0.05). Oxidative stability was improved in the groups that received the MPBC, with significant differences at the third, seventh, tenth and eleventh week (p < 0.05). SCC was also significantly lower at the second, eighth and ninth week in B2 compared to the other groups (p < 0.05), while no significant effects on the macrophage, lymphocyte, and polymorphonuclear leukocyte counts were observed. In conclusion, the MPBC addition had a positive effect on sheep milk yield, oxidative stability and somatic cell count, without any negative effect on its composition.
