This study aimed to identify the effect of complete pellet feed on animal performances in both on-station and on-farm trials conducted on growing goats.
A complete pellet feed was developed with 40% roughage (rice straw) and 60% concentrate [rice polish (50%), maize crush (16%), soybean meal (20%), molasses (10%), salt (2%), Dicalcium Phosphate (1%), vitamin-mineral premix (0.5%), and pellet binder (0.5%)] for commercial goat production and the research trial was carried out on the research station and on the farmers' validation level.
The results of the experiment on the effect of the developed complete pellet feed on goat production under stall feeding condition demonstrated that feeding complete pellet feeds helped in increasing the daily body weight gain of goats (36.96 and 52.46 gm, respectively) compared to traditional semi-intensive feeding (17.76 gm) with significantly ( < 0.05) better body condition score of goats. Feed Conversion Ratio was considerably lower (5.7) in the pellet feeding group than in the other groups where no pellet feed was used (8.32 and 8.03). Significantly ( < 0.05) lower feed price per kg weight gain was also observed in the pellet feeding group (BDT 124.22) compared to other groups (BDT 203.85 and BDT 214.74, respectively).
The results suggest that complete pellet feed can be more economical for commercial goat production under the stall feeding condition, and farmers can be benefited by about 40% more compared to conventional grass, urea molasses straw, and concentrate-based feeding system.
本研究旨在确定全价颗粒饲料对生长山羊进行的站内和农场试验中动物生产性能的影响。
开发了一种全价颗粒饲料，其中含有40%的粗饲料（稻草）和60%的精饲料[碎米（50%）、玉米碎粒（16%）、豆粕（20%）、糖蜜（10%）、盐（2%）、磷酸二钙（1%）、维生素 - 矿物质预混料（0.5%）和颗粒粘结剂（0.5%）]用于商业山羊生产，研究试验在研究站和农民验证层面进行。
在舍饲条件下，关于所开发的全价颗粒饲料对山羊生产影响的试验结果表明，与传统半精养饲喂（日增重17.76克）相比，饲喂全价颗粒饲料有助于提高山羊的日体重增加量（分别为36.96克和52.46克），山羊身体状况评分显著更好（P<0.05）。颗粒饲料喂养组的饲料转化率（5.7）明显低于未使用颗粒饲料的其他组（8.32和8.03）。与其他组（分别为203.85塔卡和214.74塔卡）相比，颗粒饲料喂养组每千克体重增加的饲料价格也显著更低（124.22塔卡）（P<0.05）。
结果表明，在舍饲条件下，全价颗粒饲料对商业山羊生产可能更经济，与传统的以草、尿素糖蜜秸秆和精饲料为基础的喂养系统相比，农民可多受益约40%。
