Abstract

Ruminant animal production in the dry season is usually problematic as weight losses are experienced arising from scarcity of forages. Conservation of Water Hyacinth (WH) (Eicchornia crassipes) ensiled with Breadfruit (BF) can help to bridge this gap. This study investigated the feeding value of WH ensiled with different levels of BF (at 0, 10, 20, 30 and 40% of the total silage diet mixture) as feed for West African Dwarf (WAD) goats. Chopped WH (2-3 cm) and BF were mixed together while sawdust was included at a constant level of 10% in all treatments and designated as diets 1-5, respectively. The mixture was ensiled for 28 days. A total of 25 growing WAD goats of both sexes (5-7 months old) weighing between 4.25-5.50 kg were randomly allotted 5 experimental diets. Data on proximate composition, growth, nutrient utilization and haematology were collected and subjected to a one way analysis of variance using the General Linear Model (GLM) procedures of SAS while differences between means were separated using the Duncan’s multiple range test of the same package. The proximate composition showed significant (p<0.05) improvement in all parameters as Breadfruit increased in silage diets except for crude protein and ash. Increasing levels of BF in silage diets had a significant (p<0.05) effect on intake. Average daily gain (g/day) for goats were similar in diets 3 (36.36), 4 (39.24) and 5 (37.93) and higher (p<0.05) than those for animals on diet 1 (29.48). The feed conversion ratio for goats on diets 1 and 2 (9.65 and 9.53, respectively) were poorer than those (7.86, 7.55 and 7.81) obtained for goats fed diets 3-5, respectively. Nitrogen intake, faecal nitrogen and nitrogen loss (g/day) were higher (p<0.05) in goats fed diet 1 than in other diets. Haematological parameters improved as BF increased in silage diets. Glucose values (54.76-86.31 mg/dL) increased (p<0.05) across diets while total protein, albumin, urea and creatinine were unaffected by silage diets. Results demonstrated that water hyacinth diets ensiled with Breadfruit have potentials as feed for ruminants with optimum results in silage diets with Breadfruit inclusion levels of 30%.

用面包果包裹水葫芦饲养西非矮山羊的生长性能、养分消化率和血液学参数

旱季的反刍动物生产通常是有问题的，因为饲料短缺会导致体重下降。用面包果（BF）青贮水葫芦（WH）有助于弥合这一差距。本研究探讨了不同水平BF（占青贮饲料总混合料的0%、10%、20%、30%和40%）对西非矮山羊（WAD）的饲喂价值。将切碎的WH（2-3cm）和BF混合在一起，同时在所有处理中以10%的恒定水平加入锯末，并分别指定为日粮1-5。将混合物青贮28天。将25只体重在4.25-5.50公斤之间的生长期WAD两性山羊（5-7个月大）随机分配到5个实验日粮中。收集了接近成分、生长、营养利用和血液学的数据，并使用SAS的通用线性模型（GLM）程序对其进行单向方差分析，同时使用同一软件包的Duncan多范围检验分离平均值之间的差异。除粗蛋白和灰分外，随着青贮饲料中面包果含量的增加，接近成分在所有参数上都有显著改善（p<0.05）。提高青贮饲料中BF水平对摄入量有显著影响（p<0.05）。第3日粮（36.36）、第4日粮（39.24）和第5日粮（37.93）中山羊的平均日增重（g/天）与第1日粮（29.48）中的动物相似，但高于（p<0.05）。饲喂日粮1的山羊的氮摄入量、粪便氮和氮损失（g/天）高于其他日粮（p<0.05）。随着青贮饲料日粮BF的增加，血液学参数有所改善。不同日粮的葡萄糖值（54.76-86.31 mg/dL）增加（p<0.05），而总蛋白、白蛋白、尿素和肌酐不受青贮饲料的影响。结果表明，用面包果青贮的水葫芦日粮具有作为反刍动物饲料的潜力，其中面包果含量为30%的青贮日粮效果最佳。
