Abstract Introduction Foot rot in small ruminants is highly contagious, causes severe lameness, and impairs fertility and wool and meat production. It is usually treated with parenteral antibiotics, with attendant antibiotic resistance risk, and with bactericidal footbaths, potentially harmful to humans and the environment. An alternative treatment in sheep is proposed based on repeated topical ozonated ointment application. Its effectiveness and safety were evaluated by estimation of acute-phase response, biochemical indicators of organic damage, and antioxidant/oxidant balance (AOB). Material and Methods The study was conducted on ten sheep with Egerton scale 2–3 lesions. Ozone application was repeated every day for seven days. Blood was drawn first (T0) after foot cleaning and before ozonation, then (T1) seven days after the first ozone application, and finally (T2) four days after the last application. Results High clinical effectiveness was observed, with total recovery by 28 days from the start of treatment. A significant increase in antiradical activity was noted on the basis of a 2,2ʹ-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) assay from 1.16 ± 0.04 μmolTe/mL at T0 to 1.23 ± 0.03 μmolTe/mL at T1, with a slight decrease in oxidative stress. Calculated on the basis of antiradical capacity, AOB was higher at T1 (130 ± 19%) and decreased to 110 ± 16% at T2. Calculated on the basis of reducing power, it was 169 ± 22% at T1 and 131 ± 17% at T2. Conclusion These results indicated that the AOB is efficient enough to prevent oxidative organ injury and the applied doses of ozone are safe for animals.

Sheep Production

Small ruminants have been one of the first domesticated species and from their origins have produced multiple benefits to humans. In the last two centuries, world sheep production has become more and more specialised upon geographical areas. But, recent changes in consumer attitudes, together with the increment in artificial fibre industries and human world population, some crisis related with the international wool market and some increments in lamb prices, have provoked that lamb meat has increased its relative importance inside the global sheep income. Also, sheep production systems vary considerably across the world, and reflect the different local environmental conditions, which determine, to a large extent, breeds, housing, levels of intensification and, at the end, local market requirements and qualities. However, among all the meats, sheep meat remains the most internationally traded (16 % of total world production is exported), which explains the potential existence of different lamb products in the same market. Then, the new requirements have created a higher interest for meat production, including its quality and quality marks. This interest from producers and the industry should be reflected in a proportional higher interest from the researches towards sheep and goat, where it exists, in general, important lacks of knowledge and, in particular, in lamb and kid meat Science. In the present speech we will made a special incidence on the relationship between carcass quality and lamb acceptability and on some factors like breed and species, diet and production system, slaughter weight and ageing time and their importance on the variation of the carcass and meat quality, including consumer acceptability.

This study aimed to determine the effects of sonication and acid whey maceration on the oxidative stability, antioxidant activity and angiotensin-converting enzyme (ACE) inhibitory activity of peptides obtained from dry-cured pork loins. The changes in the selected parameters were documented over 7, 21 and 42 days of storage. The lowest antioxidant and angiotensin-converting enzyme inhibitory activities of peptides were noted in batches with curing salt (C) and acid whey (SW) compared to batches with sea salt (S). In this sample range, the lowest oxidation–reduction power values were associated with the use of ultrasound. In addition, higher antiradical activity (against ABTS•+) and reducing power values were observed for the sea salt ultrasound (SU) batches (after 21 and 42 days) and for the acid whey ultrasound (SWU) batches (after 7 and 21 days). Contrasting results were obtained for samples with sea salt (S and SU), which were characterized by a higher content of peptides, better antiradical properties and the highest potential to inhibit ACE (after seven days).

Nutritional status during mid-gestation is often ignored under extensive husbandry. This study aimed to examine the effect of maternal undernutrition during mid-gestation on kid meat production under an extensive system. Twenty-seven goats (45 ± 3 d of gestation) were randomly assigned to an unrestricted group (100% of nutrient requirements), or a restricted group (60% of nutrient requirements from 45 to 100 d of gestation, and then re-alimented to 100%). Among the offspring, 16 eligible kids (eight per treatment) were selected, based on birth type and survival, and were harvested to evaluate the meat yield, quality, and composition at 90 d after birth. Maternal undernutrition reduced the body weight and size, average daily gain and hot carcass weight of the kids (p < 0.05). The lightness of the meat at 45 min postmortem was increased (p = 0.029) in the restricted kids. Apart from an increase in tyrosine concentration (p = 0.046), the proximate composition and the amino acid and fatty acid profiles were unaffected in the restricted kids (p > 0.05). Overall, maternal undernutrition during mid-gestation decreased the yield of kid meat, but did not significantly modify the quality and composition. These results highlight the importance of nutrient status during mid-gestation in the meat production of small ruminants under an extensive regime.

Phenolic compounds were extracted from <I>Mallotus philippinensi</I> bark using methanol. Six fractions (I–VI) were separated from the extract on a Sephadex LH-20 column using ethanol and acetone-water as the mobile phases and were evaluated for their total antioxidant activity, antiradical activity against DPPH<sup>•</sup> (2,2-diphenyl-1-picrylhydrazyl radical), and reducing power. The total phenolics and tannin contents in the fractions were determined. The content of total phenolics in the fractions ranged from 54 mg/g (fraction I) to 927 mg/g (fraction VI). Condensed tannins were detected in fractions II–VI. Total antioxidant activity (TAA) of phenolic fractions of <I>Mallotus philipinensis</I> bark extract ranged from 0.58 mmol Trolox/g (fraction I) to 6.82 mmol Trolox/g (fraction IV). Fraction IV also showed the strongest antiradical activity against DPPH<sup>•</sup> and reducing power. Several phenolic constituents in the fractions were detected by RP-HPLC using a gradient solvent system with UV-DAD detection.

Polyphenolic Antioxidants

Polyphenolic phytochemicals present in certain plant tissues exhibit multifunctional properties, in terms of expressing in vitroantioxidant activity. In the case of wines, which can be considered as very complex mixtures of polyphenols, a trend has been revealed by previous studies regarding the correlation of values from antioxidant tests based on different chemical backgrounds. In this respect, 25 aged red wines, along with some characteristic polyphenolic antioxidants, were employed to carry out specific antioxidant tests, including the widely used DPPH• stable radical and a ferric reducing assay. The results showed that the values arising from these two tests correlated very well (r2 0.8761) at a 99.9% significance level (p<0.001). On such a basis, and using the information derived from the examination of the pure components, the findings were discussed from a mechanistic point of view to examine whether particular red wine constituents are responsible for the antioxidant behaviour observed.

Samples of three types of honey: polyfloral (PH), linden (LH) and acacia (AH,) without and with addition of dried cherries (40%) were analyzed before and after three months of storage. The total phenol (TPh), flavonoid (TFd) and anthocyanin (TAn) contents, antioxidant activities and sensory properties of honeys with and without the addition of dry cherries were evaluated. TPh and TFd increased with addition of dried cherries to the honey, while enriched honeys showed high TAn. The LH sample with dried cherries showed the highest anthocyanins content (41.41mgCGE/100g). The antioxidant activity increased with addition of dried cherries in honey in the DPPH? test and reducing power. The PH and enriched PH exibited the best antiradical activity compared to LH and AH. The EC50 DPPH values were: 23.81 for PH and 24.19 mg/mL for PH, while the EC50 DPPH were: 1.16 mg/mL for PH40 and 1.18 mg/mL for PH40s. RP0.5 values were: 57.00 mg/mL for PH40 and 56.00 mg/ml for PH40s, while RP0.5 were: 15.05 mg/mL for PH40 and 15.18 mg/mL for PH40s. The statistical analysis showed that TPh, TFd and TAn, and antioxidant activity of honeys and enriched honeys showed significant correlation. Sensory analysis of honey with dried cherries, before and after storage, indicated very good sensory characteristics.

Sheep and goat production is one of the major economic activities under the arid and semi-arid condition of Pakistan. The country has 53.8 million goats and 26.5 million sheep. The main purpose of raising these small ruminants in the country is meat production. The small ruminants share about 40% of total red meat produced in the country. It has been observed that in the last several years the overall per capita consumption of the animal food products is increasing. Overall annual growth rate of goats in Pakistan is 4%, which is the highest in Asia. Pakistan ranks third in Asia in small ruminant population. Some famous sheep and goat breeds of Pakistan which have potential for mutton production will be discussed in the paper. There is no feedlot fattening system functioning in the country on a commercial level. The indicators suggest that there are good prospect for sheep and goat to be used as meat animals. In order to meet the increasing demand of mutton locally as well as for export, feedlot operations are required to be introduced among the farmer communities and in the privatesector in Pakistan.

The effect of drying on antiradical activity of Zingiber officinale (ginger) and Curcuma longo (turmeric) were studied by total phenolic content (TPC), total reducing power (TRP), 2,2'-azino-bis(3-ethyl benz thiazoline-6-sulphonicacid) (ABTS), 2,2-Diphenyl-1-picrylhydrazyl (DPPH) and superoxide radical scavenging assays. Comparing fresh and dried rhizome, optimum antiradical activity was observed in dry ginger and in fresh turmeric. The drying phenomenon diminished the scavenging capacity especially in turmeric and also ginger rhizome was exhibited highest superoxide radical scavenging solely at fresh state. The extraction parameters were standardized for maximum recovery of phenolics. The Zingiberene of ginger and curcumin of turmeric rummaged the free radicals energetically.

Five promising tanniferous tree leaves viz. Acacia nilotica, Eugenia jambolana, Ficus religiosa, L. leucocephala and Psidium guajava were selected for in vitro antioxidant and anticoccidial properties against avian Eimeria species. Condensed tannins (CT) extracts of above tree leaves were prepared in 70 % acetone and then freeze dried in lyophilizer. Antioxidant property of lyophilized acetone extract of different CT sources was evaluated by in-vitro methods. The 2, 2-diphenyl-1- picryl-hydrazyl (DPPH) free radical scavenging activity was significantly higher in P. guajava as compared to other CT sources. However, hydrogen peroxide (H2O2) scavenging activity was significantly (P less than 0.05) lower in L. leucocephala compared to other CT sources. The CT extract of A. nilotica, E. jambolana, F. religiosa and P. guajava showed significantly (P less than 0.05) higher reducing power than that of L. leucocephala. Sporulation inhibition (%) of Eimeria spp. was significantly (P less than 0.05) higher in E. jambolana and P. guajava, followed by A. nilotica, L. leucocephla and least in F. religiosa, while, E. jambolana and P. guajava showed maximum sporulation inhibition activity @ 4 mg/ml. It was concluded that CT extracts of A. nilotica, E. jambolana, F. religiosa, L. leucocephala and P. guajava leaves possess the antioxidant and anti-coccidian property. It may be eco-friendly socioeconomic alternative, natural antioxidant, anti-coccidian agent and/ or natural feed additive for organic meat production.
