Faba bean (Vicia faba minor) and pea seeds (Pisum sativum) as protein sources in lactating ewes' diets.

18 Massese lactating ewes, divided into 3 homogeneous groups for parity and milk yield, were used to evaluate the replacement effects of soybean meal by Faba bean (Vicia faba minor) and Pea (Pisum sativum) seeds. During a 70 days trial (beginning after weaning: 30±1.5 days after lambing) animals were fed three isonitrogenous and isocaloric diets. Each diet was characterised by the presence of only one protein feed. The diets consisted of alfalfa hay (1.1 kg/head/d) and a decreasing amount of mixed feed (from 1.1 to 0.7 kg/head/d) to fit animals' requirements. Milk yield, milk chemical composition, animals live weight and BCS, health state and hematochemical parameters were regularly monitored. No diets palatability problems were detected. No significant differences resulted for live weight, BCS, milk yield and milk chemical composition, except for milk protein: higher for faba bean (6.54%) and soybean (6.39%) respect pea (5.66%) diets, P<0.05. No differences resulted for blood parameters too and no clinical signs of illness were observed. Therefore faba bean and pea seeds seem to be able to replace the soybean well

Apparent digestibility of three diets in the Amiata breed donkey during lactation

The aim of the trial was to evaluate the apparent digestibility of three isonitrogenous and isocaloric diets for lactating donkeys: a diet with 8 kg of hay and 1.5 kg of commercial flaked mixed feed (CM) (Diet 1); a diet with 7 kg of hay and a 2.2 kg of CM (Diet 2) and a diet with 7 kg of hay, 1.5 kg of CM, 200 ml of corn oil and 0.2 kg of soybean meal (Diet 3). Four pluriparous donkeys (309±12 kg BW) at approximately 2-4 months of lactation were used. The trial was conducted according to a 3x3 Latin Square design with 1 or 2 subject per each cell. Feed and faeces samples were analysed for DM, OM, CP, EE, CF, NDF, ADF and gross energy. Acid insoluble ash was used as marker to calculate the apparent digestibility. The apparent digestibility of the main dietary components showed not significant differences among the three diets but generally they were lower in Diet 3. DM intakes of every diet exceeded the esti- mated energy requirement, whereas protein requirements were not significantly satisfied by Diet 1

Effect of different oils administration on oleic and linoleic serum profile in horses during standardised exercise test on treadmill

Because of its energy density, fat is often added to the diet for exercising horses; however, little attention has been given to the effect of dietary fatty acid composition. The aims of this study were to compare the effect of two diets containing different oils on the fatty acids haematic profile during and after an aerobic exercise test on treadmill. Four adult trained gelding Standardbred (mean BW=481±27 kg) were used in a two replicated 2x2 Latin Square design. Mixed hay-concentrate diets contained corn oil (CORN) or a mix of mono-di and triglycerides of olive oil (MDTO) were administrated. The horses received the diets for a period of four weeks. At the end of the adaptation period an aerobic exercise test on treadmill (30-min long) was carried on. Blood samples were collected at rest, after 15' and 30' of exercise and during recovery period (at 10', 30' and 60'). Serum fatty acid concentration was determined. MDTO supplemented horses showed an higher percentage of Oleic acid during and after the exercise test; whereas Linoleic acid showed a significant difference (P<0.05) between groups with the highest value at 10' and 30' after exercise in the CORN supplemented group

Total mixed ration in exercising horse: digestibility and nitrogen metabolism

The aim of this study was to evaluate the apparent digestibility of a total mixed ration (TMR) versus a traditional mixed hay/cereals diet. Four adult trained Standardbred geldings – BW = 478±37 kg - were used. The two diets consisted of 20 kg of a commercial TMR - corn silage, alfalfa hay, wet brewers' grain, oat, apple pomace, molasses cane, soybean oil and mineral/vitamin supplement - (Diet 1) or 7 kg of meadow hay and 4.5 kg of cereal-mix - corn, oat, barley and protein/mineral/vitamin supplement - (Diet 2). The trial was conducted according to a Latin Square design (2x2). After an adaptation period of four weeks, total faeces and urine were collected for 6 days. Both feed and faeces samples were analysed for DM, OM, CP, EE, CF, NDF, ADF, cellulose, hemicellulose, ADL and GE. Data were analysed by ANOVA. The apparent digestibility and nitrogen balance of the two diets were compared. DM, OM, CP and GE apparent digestibility were significantly different between the diets, with higher values for unifeed diet than traditional diet. Energy requirement was satisfied by both diets (96.54 vs 95.55 MJ). Nitrogen balance showed negative values in both diets (- 61.67 vs - 9.05), but the hay/cereals supplemented diet showed the best protein utilisation

CXCL12 prolongs naive CD4 + T lymphocytes survival via activation of PKA, CREB and Bcl2 and BclXl up-regulation

Naive T lymphocytes recirculate through the body, traveling from secondary lymphoid organs through tissues and via lymphatic vessels and peripheral blood into other secondary lymphoid organs and into the bone marrow. In these tissues, lymphocytes are exposed to the chemokine CXCL12 which is abundantly produced in bone marrow and in lymph nodes by stromal cells. CXCL12 is known to drive lymphocytes chemotaxis and, in cells types such as stem cells, an antiapopototic effect has been described. Methods Here we analyzed the effect of CXCL12 exposure on naïve CD4 + T lymphocytes purified from peripheral blood by immunomagnetic negative isolation and cultured in a nutrient poor medium. We also studied, mainly by western blot analysis, the signaling pathways involved in CXCL12 action on naïve CD4 + T lymphocytes. Results We found that CXCL12-exposed cells survived longer than untreated ones and this prolonged lifespan was specific for resting naïve lymphocytes, while in vitro activated lymphoblasts died rapidly despite CXCL12 treatment. We demonstrated that the increased percentage of living cells observed upon CXCL12 administration was not due to induction of proliferation but to a prosurvival effect of this chemokine. Moreover, our data suggest that this prosurvival effect on naïve CD4 + T lymphocytes might likely be mediated by PKA-dependent CREB activation and consequent increased expression of the antiapoptotic factors Bcl2 and BclXl. Conclusions This newly reported activity of CXCL12 might contribute to the maintenance of the naïve T lymphocytes pool in vivo, which is needed to ensure a proper immune response to new antigens

Aflatoxins M1 and M2 in the milk of donkeys fed with naturally contaminated diet

For its nutritional composition, donkey milk is an excellent alternative to breast milk for infants suffering from cow’s milk allergies. Even in donkeys, a passage of aflatoxin from contaminated feed to milk could occur, as reported by many authors in other dairy species, but there are no studies on this topic. This work was aimed at studying the excretion of aflatoxin M1 (AFM1) and M2 (AFM2) in milk after feeding trials with contaminated feed. Six donkeys, at the end of lactation, received a diet with naturally contaminated corn containing 202 and 11 μg.kg−1 of aflatoxin B1 (AFB1) and aflatoxin B2 (AFB2), respectively. Individual milk samples were analyzed for AFM1 and AFM2 for 15 days after the contaminated feed administration. Amounts of AFM1 and AFM2 were detected in the milk. The steady state condition was reached after 6 days. No AFM1 or AFM2 were detected in milk after 28 h from the last contaminated feed administration. The carryover from AFB1 to AFM1 and from AFB2 to AFM2 was found to be 0.02 and 0.31%, respectively. The results obtained in this study are thus a further step toward understanding the possible carryover of aflatoxin in donkey milk

Fortification of dairy goats’ products with various selenium sources

The aim of this study was to evaluate the effects of two dietary selenium (Se) sources in dairy goat’s milk and cheese. Twentyone goats were allocated to 3 dietary treatments: control (C) with 0.07 mg of Se/kg dry matter (DM); Se yeast (SeY) with 0.14 mg of total Se/kg DM; and sodium selenite (SeNa) with 0.14 mg of total Se/kg DM supplementation. Individual blood and milk samples were collected to determine the Se content. Three cheese wheels were made from each group at three different time, and the Se content was determined. The enumeration of dairy microorganisms was also performed. The SeY group showed a significantly higher milk Se content (P&lt;0.05) than the SeNa group with 44.71 vs 39.29 μg/l, respectively. Both values were also significantly higher (P&lt;0.01) than that of the group C (31.19 μg/l). The SeY group showed a significantly higher Se carryover value (31.29%, P&lt;0.05) than the SeNa group (26.95%). Both values were significantly (P&lt;0.01) lower than in the C group (49.66%). Significant differences were also observed in cheese Se content among the 3 groups. The average Se content in cheeses from groups C, SeY, SeNa was 230 μg/kg, 353 μg/kg and 306 μg/kg, respectively. Se yeast supplementation influenced Se concentration in goat’s milk and cheese but, unlike other authors, we also observed an increase of Se concentration in milk and cheese supplemented with SeNa, although to a smaller extent. Our results indicate that Se yeast supplementation seems to be the best fortification source for dairy goat’s products. In several countries the selenium intake is considered to be low in the human diet, the consumption of Se-enriched products could represent a good way to prevent the deficit in the Se intake currently reported in many countries

Three-Dimensional Virtual Anatomy as a New Approach for Medical Student’s Learning

none8noMost medical and health science schools adopt innovative tools to implement the teaching of anatomy to their undergraduate students. The increase in technological resources for educational purposes allows the use of virtual systems in the field of medicine, which can be considered decisive for improving anatomical knowledge, a requisite for safe and competent medical practice. Among these virtual tools, the Anatomage Table 7.0 represents, to date, a pivotal anatomical device for student education and training medical professionals. This review focuses attention on the potential of the Anatomage Table in the anatomical learning process and clinical practice by discussing these topics based on recent publication findings and describing their trends during the COVID-19 pandemic period. The reports documented a great interest in and a positive impact of the use of this technological table by medical students for teaching gross anatomy. Anatomage allows to describe, with accuracy and at high resolution, organ structure, vascularization, and innervation, as well as enables to familiarize with radiological images of real patients by improving knowledge in the radiological and surgical fields. Furthermore, its use can be considered strategic in a pandemic period, since it ensures, through an online platform, the continuation of anatomical and surgical training on dissecting cadavers.openBartoletti-Stella, Anna; Gatta, Valentina; Mariani, Giulia Adalgisa; Gobbi, Pietro; Falconi, Mirella; Manzoli, Lucia; Faenza, Irene; Salucci, SaraBartoletti-Stella, Anna; Gatta, Valentina; Mariani, Giulia Adalgisa; Gobbi, Pietro; Falconi, Mirella; Manzoli, Lucia; Faenza, Irene; Salucci, Sar
