在南方亚热带人工草地上以云岭黑山羊为试验家畜,进行不同季节、不同牧压下的草场供给量、山羊采食量和山羊日增重的测定。结果表明:山羊日增重依赖于采食量,随着采食量的增大,山羊日增重也随之升高;高载畜率组山羊平均日增重为78 g/d,... 在南方亚热带人工草地上以云岭黑山羊为试验家畜,进行不同季节、不同牧压下的草场供给量、山羊采食量和山羊日增重的测定。结果表明:山羊日增重依赖于采食量,随着采食量的增大,山羊日增重也随之升高;高载畜率组山羊平均日增重为78 g/d,低载畜率组山羊平均日增重为113 g/d,高载畜率组较低载畜率相差44.9%,两者差异显著(P<0.05);牧草品质会影响放牧山羊采食量。 展开更多

在南方高海拔山区,研究不同放牧强度(7.5、15、30和45羊/hm2)和放牧季节对人工改良草地和家畜生产性能的影响,对不同季节人工改良草地适宜载畜量进行探讨。结果表明:不同放牧强度对地上现存量和家畜生产性能有显著影响(P<0.05)。地... 在南方高海拔山区,研究不同放牧强度(7.5、15、30和45羊/hm2)和放牧季节对人工改良草地和家畜生产性能的影响,对不同季节人工改良草地适宜载畜量进行探讨。结果表明:不同放牧强度对地上现存量和家畜生产性能有显著影响(P<0.05)。地上现存量(Yh,g/m2)与放牧率(S,羊/hm2)之间呈线性负相关;日增重(Ya)和放牧率(S)之间呈线性负相关;公顷增重(Gh)和放牧率(S)之间呈二次方相关;冬春和夏秋季节公顷最大增重时的适宜放牧率分别为10.7和30.3羊/hm2,最大地上现存量分别为134.1 g/m2和153.8 g/m2,表明南方人工改良草地冬春季节和夏秋季节适宜的草地利用率分别为35.7%和65.7%。 展开更多

A low liveweight gain of of Kacang goats when given grass as single feed indicated that additional feed is required to increase their gowth performance. This study was done to examine the effect of addition of Gliricidia (Gliricidia sepium) leaf or rice bran on feed intake, feed digestibility and liveweight gain of Kacang goat given Mulato (Brachiaria mulato) grass. Twenty four male Kacang goat, approximately 13.4±0.6 kg in initial weight and 10 months of age, were housed in individual metabolic pen and allocated to one of three dietary treatments. The experimental design was a completely randomized block design, with three treatments and eight replicates (goats). The treatments were Mulato grass ad libitum (M), Mulato + Gliricidia (1% weight/d on dry matter basis) (MG), and Mulato + rice bran (1% weight/d on dry matter basis) (MR). The experiment was run for eight weeks period (two weeks for adaptation and and six weeks for measurement period, respectively). Parameters measured were liveweight gain (LWG), dry matter intake (DMI) and dry matter digestibility (DMD). The result showed that dietary treatment significantly (P 〈 0.05) affected the LWG, DMI and DMD of Kacang goat. Goat given Mulato grass had the lowest LWG, DMI and DMD with value 58 g/d, 2.77% weight/d and 57.61%, respectively. Goat received Mulato + Gliricidia and Mulato + rice bran had a significant higher LWG (73 g/d and 76 g/d, respectively), DMI (3.25% weight/d and 3.65% weight/d, respectively) and DMD (62.28% and 63.19%, respectively). However, no significant difference (P 〉 0.05) between goat received Mulato + Gliricidia and Mulato + rice bran. In conclusion, this study demonstrated that protein or energy contents of the diet influenced growth, feed intake and digestibility of Kacang goat. 展开更多
