In this study, nutritional and digestibility value of tomato pomace before (TP) and after oil extraction (DTP) were measured. Lycopene content of TP and its rumen disappearance rate was determined. In a completely randomized design, gas production content of TP and DTP was measured in vitro. Ruminal disappearance of dry matter and lycopene of TP were determined at 0, 2, 6, 12, 24, 36, 48, 72 and 96 hours of incubation using fistula cows. Ruminal degradability parameters including rapidly degraded fraction (a), slowly degraded fraction (b), fractional rate of degradation (c), potential of degradability (PD) and effective degradability (ED) were estimated. Results showed that lycopene content of TP was 168 mg/kg DM. DTP contained higher crude protein, NDF, and ADF than TP. De-oiled TP showed higher gas production, digestibility of organic matter and short-chain fatty acids and lower N-ammonia as compared to TP. The values for a, b, c, PD and ED for dry matter were 57.1, 0.07, 66.4 and 49.3% and for lycopene were 3.87, 42.1, 0.076, 45.9 and 34.1, respectively. In conclusion, ruminal degradability of lycopene was about 30% meaning that about than 70% of lycopene by-passes the rumen. Moreover, de-oiled tomato pomace has reasonable nutritive values to be used in ruminant nutrition.

Abstract
In this study, effect of lycopene and corn supplementation on quantity of colostrum and concentrations of IgG in blood and colostrum in pregnant ewes was investigated.A total of 40 multiparous single-bearing ewes (body weight 68 ±8.4 kg) during last month of gestation were fed with one of the ...

In this study, effect of lycopene and corn supplementation on quantity of colostrum and concentrations of IgG in blood and colostrum in pregnant ewes was investigated.A total of 40 multiparous single-bearing ewes (body weight 68 ±8.4 kg) during last month of gestation were fed with one of the four experimental diets including; basal diet (CON), basal diet plus 1 g/d lycopen (LYC), 300 g/d corn (COR), 1 g/d lycopen plus 300 g/d corn (LYC + COR). Quantity of colostrum production was determined at 6 h post-partum using oxytocin injection method.The IgG concentration in colostrum at 6 and 12 h post-partum as well as at 14 and one day pre-partum was determined. Quantity of colostrum at 6 h post-partum in COR, and LYC + COR was higher (P<0.05) than that in CON and LYC. Blood IgG concentration in CON was significantly lower than COR, LYC, and LYC + CORN. Ewes in LYC+COR had higher (P<0.05) colostrum IgG concentration than ewes in CON. In conclusion, lycopene and corn supplementation during late gestation increased serum IgG concentrations and improved colostrum quantity and quality in pregnant ewes.
