Effect of dietary extruded linseed, verbascoside and vitamin E supplements on selected serum biochemical parameters and plasma oxidative status in Lacaune ewes
Selected serum biochemical parameters and plasma oxidative status were evaluated in Lacaune ewes on a diet supplemented with extruded linseed, verbascoside and vitamin E. A 98 day-trial was conducted on 44 ewes and started 40 ± 2 days post partum. The animals were divided into four homogeneous groups of eleven animals each; one control group (CON) with a basal diet, and the other three experimental groups supplemented with extruded linseed (L group), extruded linseedverbascoside (LVB group) and extruded linseed-verbascoside-vitamin E (LVBE group). All animals individually received an isoproteic and isoenergetic diet, consisting of 700g of concentrated feed and meadow hay ad libitum. Blood sampling of the ewes was performed three times: at the beginning (0 d), midway (49 d) and end of the trial (98 d). The following parameters were determined: triglycerides, total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, bilirubin, alanine aminotransferase, aspartate aminotransferase, thiobarbituric acid reactive substances (TBARS), reactive oxygen metabolites (ROMs), vitamin A and vitamin E. Dietary integration in the LVB and LVBE groups resulted in an improvement in the blood profile, characterized by a significant (P=0.001) increase in HDL cholesterol and a marked decrease in triglycerides (P=0.001), total cholesterol (P=0.017), LDL cholesterol (P=0.001) and bilirubin (P=0.035), due to the verbascoside supplementation. In the same groups, there was an increase in blood vitamin A (P=0.002) and vitamin E (P=0.001), and a reduction (P=0.001) in ROMs and TBARS, with an improved plasma oxidative status. The dietary vitamin E integration did not produce a significant improvement in the parameters studied, with no statistical differences between LVB and LVBE groups. Animal feed containing extruded flaxseed, might therefore benefit from the addition of a verbascoside supplement, because of the positive effect showed by this molecule on the blood parameters
Effect of dietary phenylpropanoid glycoside-based natural extracts on blood parameters and productive performance in intensively-reared young hares
Two different doses of a dietary verbascoside based supplement were evaluated on some various blood parameters and on productive performance in young weaned hares (28d old), reared intensively from 28 to 90 days. The study lasted 62 days and was conducted on 210 young hares divided into three homogenous groups of 70 animals each, consisting of a control group and two experimental groups. Each group received the dietary supplement in the feed, titrated to 0.5% verbascoside, 1 kg/t of concentrate (LVB group) and 2 kg/t of concentrate (HVB group). The experimental reliefs included the measurement of blood parameters such as triglycerides, total cholesterol, high density lipoprotein cholesterol, and bilirubin, along with some markers of oxidative status in plasma such as reactive oxygen metabolites, thiobarbituric acid-reactive substances, and vitamins A and E. Various productive parameters were also measured such as body weight and growth rate, food consumption and feed conversion. The experimental treatment resulted in a significant decrease in triglycerides (P<0.01) and bilirubin (P<0.05) and an increase in high density lipoprotein cholesterol (P<0.01 ) in the LVB and HVB experimental groups. In addition, the oxidative plasma stability in the blood also improved, with a significant decrease in the concentration of reactive oxygen metabolites (P<0.01) and thiobarbituric acid-reactive substances (P<0.01), together with increased levels of vitamin E (P<0.05). The productive performance was not statistically influenced by the experimental treatment, except for the growth rate which increased significantly (P<0.05) in the experimental LVB and HVB groups: 6.9% and 8.7% respectively compared with the control group
GnRH – PGF2alpha and PGF2alpha – FGA SHORT TERM (5 d) ESTRUS SYNCHRONIZATION PROTOCOLS IN IONICA GOAT
SYNCHRONIZATION OF OESTRUS IN GOATS WITH PROGESTOGEN SPONGES AND SHORT TERM COMBINED FGA, PGF2Α PROTOCOLS
The study aimed to evaluated the reproductive performance response to short term oestrus synchronization during the transition period. One hundred and sixty-five indigenous multiparous non-lactating goats were subdivided into the following six treatment groups for oestrus synchronization: NT control Group (N= 30), Fe-21d, FGA vaginal sponge for 21days+eCG at 19 thd; FPe- 11d, FGA 11d + PGF2α and eCG at 9 th d; FPe-10d, FGA 10d+ PGF2α and eCG at 8 th d; FPe-9d, FGA 9d +PGF2α and eCG at 7 thd; PFe-5d, PGF2α at d0 + FGA 5d + eCG at 5 thd. The goats were natural mated (1 male/6 females). Fecundity rates (n. births /n. females treated x 100) were statistically higher (P<0.05) in short term FPe-9d (157.9%), FPe- 11d (115.4%), FPe-10d (111.1%) and PFe-5d (107.7%) groups compared to the NT control Group (66.7%)

Effects of verbascoside on plasma oxidative status and blood and milk production parameters during the peripartum period in Lacaune ewes
This study examined the effect of administration of verbascoside on plasma oxidative status and on specific blood and milk production parameters in Lacaune ewes during the peripartum period. The trial, lasting 60 d, ran from 20 d before lambing until 40 d after and was conducted on 40 ewes in their 5th month of gestation. The animals were divided into two equal groups of 20: a control group CON, which did not receive food supplement, and the experimental group V, which received a supplement of verbascoside in their feed. Consumption of the supplement, which was 2 g/ewe/d, was assured by individual and daily administration of feed. The animals received a pellet feed concentrate at a rate of 400 g/ewe/d prepartum and 700 g/ewe/d postpartum. The ration was completed with mixed hay ad libitum. The experimental measures included body weight; blood samples 20 d before lambing and 0 d, 20 d and 40 d after lambing; body condition score; individual yield and quality of milk. The administration of verbascoside significantly improved milk yield by 9.3% (P < 0.01), significantly decreased triglycerides, total cholesterol, low-density lipoprotein cholesterol, alanine transferase (P < 0.01) and bilirubin (P < 0.05), and increased high density lipoprotein cholesterol (P < 0.01). Furthermore, the parameters of oxidative status in plasma were positively influenced by the use of dietary verbascoside, which resulted in significant decreases in reactive oxygen metabolites (P < 0.01) and thiobarbituric acid-reactive substances (P < 0.05) and increases in vitamins A and E (P < 0.01).The use of verbascoside during the peripartum period provided benefits on some blood parameters, oxidative status and milk production, particularly in the immediate postpartum period (0–20 d)
Trattamento con laser ER:YAG delle lesioni cariose. Valutazione al SEM del tessuto dentinale
Scopo del lavoro. Riportare le osservazioni effettuate al microscopio elettronico a scansione (SEM) della
dentina del fondo cavitario, trattata con laser ErYAG per 5 secondi e mordenzata con acido ortofosforico
al 37% per 30 secondi.
Materiali e metodi. Sono stati considerati quattro gruppi di campioni: il primo di controllo; il secondo
preparato con turbina e mordenzato con acido ortofosforico al 37% per 30 secondi; il terzo trattato con
laser ErYAG per 5 secondi a 250 mj e 4 Hz, seguito da mordenzatura con acido ortofosforico al 37% per
30 secondi; il quarto trattato sempre per 5 secondi con lo stesso laser a parametri più estremi, cioè a
350 mj e 6 Hz, seguito da mordenzatura con acido ortofosforico al 37% per 30 secondi.
Risultati e conclusioni. E' stato rilevato che il trattamento con laser ErYAG per 5 secondi a 250 mj e 4 Hz,
seguito da mordenzatura con acido ortofosforico al 37% per 30 secondi, determina un migliore aspetto
della superficie dentinale, che appare caratterizzata da tubuli pervi e "a cratere di vulcano" e manca di
"melting" e "craking" migliorando l'adesione dei materiali compositi comunemente usati per il restauro
