Öğe Effects of a bacterial silage inoculant on corn silage fermentation and nutrient digestibility(Elsevier Science Bv, 2004) Aksu, T; Baytok, E; Bolat, DTwo type silage were prepared, the control had no additives and the other silage with a bacterial inoculant (BONSILAGE(R). Both of them were stored in 100 kg capacity plastic containers for two months and silage pH, organic acids and nutrient digestibility were investigated. In control and inoculated silage pH were 3.90 and 3.63 (P < 0.05), amount of lactic acid 16.75 and 22.45 9 kg(-1) DM (P < 0.05), acetic acid 49.48 and 51.65 g kg(-1) DM, and butyric acid 7.12 and 5.44 g kg(-1) DM (P < 0.05), respectively. Eight Morkaraman sheeps, 2 years old, were used to determine nutrient digestibility of corn silages. In control and inoculated silages, the degrees of digestibility of DM were 59.73, 68.53%, OM 64.10, 66.95%, CP 48.39, 50.30%, NDF 63.35, 66.11%, and ADF 55.33, 59.35%. In conclusion, corn silage fermentation and digestibility of DM and NDF were increased (P < 0.05) by the bacterial inoculation (C) 2004 Elsevier B.V.

This study evaluated the effects of dietary lead exposure and ascorbic acid on performance, serum biochemical parameters, plasma malonclialdehyde and lead accumulation in broiler chickens. For this purpose, lead acetate at 200 mg/kg and ascorbic acid at 100 mg/kg were added to the diet alone or in combination for 42 days. A total of 120 broiler chicks were divided into 4 treatment groups: control, ascorbic acid, lead, and lead + ascorbic acid. By the end of the study, lead caused body weight and body weight gain to decrease significantly, although its effects on feed consumption and the feed conversion ratio were not significant. While lead did not alter the serum lactate dehydrogenase, aspartate aminotransferase or alanine aminotransferase activities or albumin or total protein concentrations, it increased malondialdehyde (P < 0.001) and triglyceride (P < 0.01) levels. Although the lead contents of the serum and muscle were unchanged, lead was accumulated in the liver and kidneys (P < 0.001). Our results showed that lead (200 mg/kg diet) had an inhibitory effect on the growth of broilers and appeared to be inducing lipid peroxidation. The addition of ascorbic acid to the diet reduced the plasma malondialdehyde levels induced by lead and tended to reduce the inhibitory effect of lead on growth. It is concluded that the addition of higher doses of ascorbic acid to the diet may be more efficacious in fully reversing the negative effect of lead on growth.Öğe Effects of formic acid, molasses and inoculant additives on corn silage composition, organic matter digestibility and microbial protein synthesis in sheep(Elsevier, 2006) Aksu, T; Baytok, E; Karsli, MA; Muruz, HThis study examined the production of com silages with low or high lactic acid concentrations, provided by the addition of formic acid (0.5%), molasses (5%) or microbial inoculant (homofermentative lactic acid bacteria, 10 g/tonne). After the fermentation period, sheep were fed the silages to determine true and apparent digestibility of the organic matter and microbial protein synthesis. The experiment were carried out with four KivircikxMorkaraman sheep, 1.5 years old, fixed with cannula in their rumen and duodenum. Lactic acid concentrations were significantly higher in silages treated with enzyme or molasses compared to other specific treatments. Acetic acid concentration was highest in silage treated with formic acid, and lowest in silage treated with molasses (P < 0.05). The by-pass of crude protein was highest in silage treated with formic acid. (c) 2005 Elsevier B.V.

Silages with or without formic acid (0.5%), molasses (5%), or microbial inoculant (10 g/t) were fed to ruminally cannulated, 1.5 year-old Kivircik x Morkaraman sheep. Silage treated with molasses had significantly greater DM and CP concentrations compared with other groups (P < 0.05). pH values did not significantly differ among treatments (P > 0.05). Lactic acid concentrations were significantly higher in silages treated with enzyme or molasses compared with others (P < 0.05). While acetic acid concentration was the highest in silage treated with acid, it was the lowest in silage treated with molasses (P < 0.05). Silage NH3-N concentration was the highest in silage treated with molasses, but the lowest in silage treated with acid (P < 0.05). Post-feeding ruminal total organic acid concentrations were significantly greater in sheep fed silages with additive than the control (P < 0.05). While percentages of acetic acid were greater, percentages of butyric acids were less in the rumen fluid of sheep fed silage without additive compared with the rumen fluid of sheep fed silage treated with silage additives. However, percentages of propionic acid did not differ among treatments.Öğe The effects of laminitis on milk yield and milk composition of sheep(Indian Veterinary Journal, 2004) Tas, A; Isleyici, O; Baytok, E; Cak, B; Savran, A; Demirel, E; Ceylan, E[Abstract Not Available]
