Determination of nutritive value of citrus tree leaves for sheep using in vitro gas production technique
(Asian-Australasian Association of Animal Production Society, 2006-06-29) Özkan, Çağrı O.; Kamalak, Adem; Karabulut, Ali Nedim; Canbolat, Önder; Uludağ Üniversitesi/Ziraat Fakültesi/Hayvan Bilimleri Bölümü.; F-4308-2010; 7005308670; 7004338636
The nutritive values of leaves of Citrus grandis, Citrus aurantium, Citrus oranges, Citrus limon, and Citrus deliciosa were evaluated by chemical composition and in vitro gas production techniques. There were significant (p < 0.001) differences among citrus species in terms of chemical composition. Crude protein (CP) contents ranged from 123.0 to 148.3 g/kg DM. Neutral detergent fibre (NDF) and acid detergent fibre (ADF) contents were varied with species in the range 219.4-355.4 and 215.0-278.8 g/kg DM respectively. Condensed tannin (CT) contents were ranged from 5.9 to 10.2 g/kg DM. The PEG addition significantly (p < 0.001) increased the gas production and some estimated parameters of citrus tree leaves. However, species showed variable responses to polyethylene glycol (PEG) treatment. There were also significant (p < 0.001) differences among species in terms of gas production and estimated parameters. The OMD and ME contents of citrus leaves without PEG supplementation were ranged from 66.5 to 73.3% and 9.8 to 10.9 MJ/kg DM respectively. The improvement in gas production, organic matter digestibility (OMD) and metabolizable energy (ME) with PEG emphasized the negative effect of tannins on digestibility. The increase (%) in the estimated OMD and ME contents ranged from 5.5 to 9.8% and 5.7 to 10.2% respectively. All citrus tree leaves studied in this experiment have potential nutritive values indicated by high crude protein content, OMD, ME and low fiber values.

A total of 420 male day-old-chicks of a slow-growing genetic line (Hubbard ISA Red JA) were used as the trial material. The treatment groups were: Dilute-AL (energy and protein diluted diet fed ad libitum), Dilute-R (restricted energy and protein diluted diet), High-AL (high energy and protein diet fed ad libitum) and High-R (restricted high energy and protein diet). Restricted birds showed a greater percentage of time spot pecking, preening and in feather maintenance and less time resting than birds fed ad libitum but the differences were relatively small.
The effect of vitamin E and vitamin C on the performance of Japanese quails (Coturnix coturnix Japonica) reared under heat stress during growth and egg production period
(Asian-Australasian Association of Animal Production Society, 2006-11-27) İpek, Aydın; Canbolat, Önder; Karabulut, Ali Nedim; Uludağ Üniversitesi/Ziraat Fakültesi/Hayvan Bilimleri Bölümü.; AAH-2551-2021; 56208332300; 7004338636; 7005308670
This study was carried out to determine the effect of vitamin E and vitamin C on the performance of Japanese quails (Coturnix coturnix japonica) reared under heat stress during the growth and egg production period. A total of 8 10 seven-day-old Japanese quails were used in the trial. The birds received a diet with either three levels of vitamin E (DL-alpha Tocopheryl acetate) (60, 120 and 240 mg/kg of diet) and vitamin C (ROVIMIX STAY-C 35) (60, 120 and 240 mg/kg of diet). Live weight on day 35 and weight gain were the lowest in the group of chicks on a combination of 60 mg of vitamin E and 60 mg of vitamin C, whereas the highest live weight was demonstrated in chicks on a combination of 240 mg of vitamin E and 240 mg of vitamin C (p < 0.01). The effects of treatments on cumulative feed consumption, feed conversion ratio, age at 5% lay, sexual maturity weight, rate of lay and mean egg weight values were found to be significant (p < 0.01). The highest feed consumption, feed conversion ratio, age at 5% lay, sexual maturity weight, rate of lay and mean egg weight values were found in the group on a combination of 240 mg of vitamin E and 240 mg of vitamin C. The effect of treatments on the mortality ratio was found to be insignificant (p > 0.01). The cost of supplementing diets with vitamin E and vitamin C is very low. Therefore such a combination of supplement can offer a potential protective management practice in preventing heat stress related losses in performance of Japanese quails.
