Abstract
The objective of this experiment was to study the effect of diet containing high (40.7 %) non fibrous carbohydrates on some inflammatory and native immunity related genes expression in lactating Jersey cows. Seven lactating multiparous (2.5 ± 0.5) Jersey cows with 71 ± 3 days in milk ...

The objective of this experiment was to study the effect of diet containing high (40.7 %) non fibrous carbohydrates on some inflammatory and native immunity related genes expression in lactating Jersey cows. Seven lactating multiparous (2.5 ± 0.5) Jersey cows with 71 ± 3 days in milk and 28 ± 6.6 kg of average milk production were used. All cows received a control diet containing low (34.3 percentage of dry matter) non fibrous carbohydrates content for the first 14 days and then were were switched to a diet containing high (40.7 percentage of dry matter) non fibrous carbohydrates content for one week. Blood samples were collected on day 0 (After 14 days of feeding control diet) and days 4 and 7 after feeding high NFC diet. Relative gene expression of seven genes (IL1-β, TNF-α, MNDA, CD74, TLR2, SELECTIN, TGF1-β) were measured. The results showed that gene expression of the pro-inflammatory cytokines (IL1-β and TNF-α) and anti-inflammatory proteins (MNDA, D74, TLR2, SELECTIN, TGF1-β) was down regulated during feeding of high NFC diet (p < 0.05). These data indicated that feeding a high non-fibrous carbohydrates diet caused inflammation and affected immunity system in lactating Jersey cows.

Mulberry powdery mildew is the most important fungal disease in silkworm rearing zones. Resistance of mulberry varieties is different against this disease. The mulberry varieties have different resistance against powdery mildew disease. Percentage of moisture, nitrogen, protein, phosphor, fiber, calcium and ash of powdery mildew infected leaves and healthy control in five mulberry varieties including Kenmochi, Local, Kaironozomi, Ichinose and Shinichinose were determined. Meanwhile, larvae mortality percentage, pupae mortality percentage, total produced cocoon weight, cocoon weight, single cocoon shell weight and percentage, and produced cocoon number recorded after larvae feeding with control and infected leaves. The obtained results showed that powdery mildew disease resulted to nutrients decline in mulberry leaves and economical parameters in those larvae which fed with infected leaves (P< 0.01). Moisture percentage, protein, percentage, nitrogen, phosphor, calcium decreased after powdery mildew infectious for each five races. Meanwhile, pupae mortality percentage, single cocoon weight, single cocoon shell weight and percentage, and produced cocoon number decreased after feeding with infected leaves for total five varieties significantly (P< 0.05). Therefore, quality decline of mulberry leaf under powdery mildew disease resulted to decreasing of silkworm performance in rearing process.
