Two series of investigations were carried out to determine some of the rumen metabolism abjustments in response to high environmental temperature on Chinese female buffaloes with rumen fistula in summer in Nanjing.Series I of experiments carried out on four regional buffaloes fed on herbage, showed that moderate high enviromental temperature ( mean 31. 3 C° ) reduced voluntary feed intake ( VFI ) by 17% and elevated rectal temperature ( TR ) , rumen temperature ( TRu ) and respiratory rate...

Two series of investigations were carried out to determine some of the rumen metabolism abjustments in response to high environmental temperature on Chinese female buffaloes with rumen fistula in summer in Nanjing.Series I of experiments carried out on four regional buffaloes fed on herbage, showed that moderate high enviromental temperature ( mean 31. 3 C° ) reduced voluntary feed intake ( VFI ) by 17% and elevated rectal temperature ( TR ) , rumen temperature ( TRu ) and respiratory rate ( Rr ) , And did volatile fatty acid ( TVFA ) concentration from 8.55±0.89 to 9,46±0.43 mM.per 100ml ruminal fluid ( SRF ) and the ratio of acetic to propionic a-cid molar percentage (A/P) from 2,84 ± 0.03 to 3.38±0.17. As tie high environmental temperature continued for several days VFI was about half of the control, and TR, TRu and Rr raised progressively, Bot NH3-N and TVFA concentration reduced from 19.83 ± 0.92, 9,46 ± 0.37 to 15.69±1.07mg /100ml SRF, 7.60±0.65 mM/100ml SRF respectively and A/P from 3,36± 0.15 to 2.63 ± 0.06.It was indicated that ruminal njetabolism was elevated under the high environmental temperature which was tolerated by the animals and inhibited very seriously when the high ambient temperature continued for several days.Series I of experiments was carried out on three female Haizi tuffaloes fed on herbage in summer (mean TA 31.5 ± 1.0℃) and in early autumn ( mean TA 23.5±1.2℃ ) .As compared with autumn, in summer period Rr, TR, TRu and water intake per day were significantly elevated, aod VFI and rumen liquid flow rate were decreased by 23.8% and 36.0% ( p<0.05 ) respectively, suggesting that high environmental temperature had changed the ruminal metabolism which was regulated by animal organism particula-rly voluntary feed intake.During inhibition of rumen metabolism in heat stress, if spriskiing with tap water ( about 21癈 ) was given on whole body of the animals for half an hour, or the temperature in the rumen was lowered by icepack VFI and rumination would soon reappear and the NH3-N and TVFA concentration recovered.

利用南京地区夏季炎热的自然条件,连续两年在高温季节(7—8月)进行实验。第一年(系列Ⅰ)的实验动物为四头装置瘤胃瘘管的空怀母水牛,研究高温初期(27.5~33.4℃)和持续高温期(28.0~35℃)对水牛瘤胃消化代谢的影响。第二年实验(系列Ⅱ)利用三头装置瘤胃瘘管的海仔母水牛重复高温(26~35.3℃)实验。 夏季高温期间,实验水牛的呼吸率、瘤胃温度和直肠温度升高,采食量减少,饮水量增加,瘤胃液流速减缓。高温初期出现瘤胃代谢升高[总挥发性脂肪酸(TVFA)和氨氮(NH_3-N)浓度及乙酸/丙酸(A/P)比率升高]。但在持续高温情况下,水牛的采食和瘤胃代谢均明显抑制。采取瘤胃内降温措施(投入冰袋)或冷水淋浴,均能迅速降低呼吸率、直肠和瘤胃温度,恢复采食和反刍,并缓解瘤胃代谢的抑制。提示动物机体参与调节瘤胃代谢的变化,并为改善水牛夏季的饲养管理提供生理学依据。

The seasonal changes in rumen metabolism of water buffaloes with the year—round variation in pasture nutrient contents were examined and compared between the coastal and inland hilly areas of Jiangsu province. The rate of breath, body temperature and pulse of the animal were also recorded. It was shown that the quality of pastures in both the areas was inferior and there was significant seasonal veriation in the content of pasture nutrients. It was suggested that the native pastures should be improved...

The seasonal changes in rumen metabolism of water buffaloes with the year—round variation in pasture nutrient contents were examined and compared between the coastal and inland hilly areas of Jiangsu province. The rate of breath, body temperature and pulse of the animal were also recorded. It was shown that the quality of pastures in both the areas was inferior and there was significant seasonal veriation in the content of pasture nutrients. It was suggested that the native pastures should be improved by increasing leguminous plants or the buffaloes should be provided with additional non—protein nitrogen to improve the level of rumen nitrogen merabolism.

为研究水牛的营养生态,本文对江苏地区东台海子水牛与盱眙山区水牛的瘤胃代谢和呼吸、体温、心博率等的季节性变化,进行了比较观察。两地牧草营养成份随季节而发生显著变化,春季粗蛋白含量两地均匀为17%以上,超出夏季一倍。秋季二倍;纤维素含量则以春季最低,夏、秋季大幅度增加,实验水牛的瘤胃中乙酸/丙酸(A/P)比率以丘陵山区水牛较高,然均属乙酸发酵类型。海子水牛春秋季的瘤胃代谢水平较高,夏季则相反。冬季含补饲少量精料,两地水牛瘤胃代谢水平接近,均低于放牧期并接近丙酸发酵类型。水牛的体温和呼吸率呈明显的季节性变化,以夏季最高,春季次之,冬季最低;山区水牛高于海仔水牛。两地自然生长的牧草品质低劣,建议应增加豆科牧草比例或添喂非蛋白氮以改善瘤胃氮化谢水平。
