Effects of incorporating duckweed into broiler finisher diets at proportions of zero (control), 10, 20 and 30 percent on performance and carcass composition were investigated using 160 male broilers. This study was carried out under controlled conditions in the Animal Bio-Assay laboratory in the University of Zimbabwe from April 1998 to June 1998. On day 21, birds were randomly allocated to one of the four dietary treatments. Diets were isonitrogenous, provided similar amounts of metabolisable energy (ME) and all other nutrients according to literature requirements. Birds were given ad libitum access to feed and water. After six weeks the birds were slaughtered and dressed weights and abdominal fat pad weights were recorded. Carcass samples were also analysed for dry matter, ash, crude protein, ether extractable fat, calcium and phosphorus. Increasing the proportion of duckweed in the diet was associated with a concomitant decrease in feed intake, weight gain, feed conversion efficiency, dressed and abdominal fat pad weight (P 0.05) in birds fed the control diet and that containing 10 percent duckweed, except for the lower (P Journal of Applied Science in Southern Africa Vol.5, No.1 pp. 25-34
以160只雄性肉仔鸡为试验对象，研究了在育肥肉饲粮中分别添加0(对照)、10%、20%和30%浮萍对生产性能和胴体组成的影响。这项研究于1998年4月至1998年6月在津巴布韦大学动物生物测定实验室的受控条件下进行。第21天，随机分配4种饲粮处理。饮食是等氮的，根据文献要求提供相似量的代谢能(ME)和所有其他营养素。鸟类可以自由地获得饲料和水。6周后屠宰，记录屠宰后体重和腹部脂肪垫重量。还分析了胴体样品的干物质、灰分、粗蛋白质、醚提取脂肪、钙和磷。饲粮中浮萍比例的增加与对照组和含10%浮萍组的采食量、增重、饲料转化效率、胴体重和腹部脂肪垫重(P < 0.05)相关(P < Journal of Applied Science in Southern Africa Vol.5, No.1 pp. 25-34)

The prevalence and population levels of VAM fungi in a range of field soil environments in Zimbabwe were determined. The main VAM genera Acaulospora, Scutellospora, Gigaspora, Glomus, Sclerocystis and Entrophospora were represented in the study sites. The relative abundance was Glomus>Scutellospora>Sclerocytis>Gigaspora>Entrophospora at all sites except at Chabwino (fallow soil) and Thorn Park (sorghum) where Acaulospora>Scutellospora and Sclerocytis>Scutellospora = Acaulospora. Relative proportions of different VAM genera were similar across soils but population sizes varied with soil management. There was no clear relationship between VAM spore numbers and cropping history although among the cultivated plots, soils that had legumes as the previous or current crop generally had higher VAM populations than under sorghum. Of the soil parameters measured, only percent organic carbon was significantly correlated with VAM numbers and infective propagules.

Ruredzo plants were collected from Bikita area in Masvingo, during the rain season from November 1993 to May 1994. The mucilage from ruredzo (Dicerocaryum Zanguebarium) was extracted from dried leaves and crosslinked with epichlorohydrin. The yield of the crosslinked mucilage (CLM) ranged from 78 percent when crude mucilage in solution was used to 95 percent when purified solid mucilage was used. The bed volume of the CLM, which ranged from 4.5 ml/g to 11.5 nl/g depending on the nature of the starting material, was influenced by pH and ionic strength of the suspending medium and by the presence of ethanol. The concentration of free carboxyl groups in the CLM ranged from 1.17 meq/g when crude solutions of the mucilage were used to 1.47 meq/g when purified solid mucilage was used.
