The world population is increasing, leading to competition between humans and animals for the use of farm produce. The use of non-conventional resources in poultry feed is increasingly being explored. Cassava (Manihot esculenta) have been studied in layers and broilers feed. However, there is very little information on the impact of the leaves on breeder hens.
This study was conducted to determine the effect of M. esculenta leaf meal (MELM) on breeder hen performance, hatching egg quality and blood parameters.
A total of 180 hens and 24 cocks Sasso breeders at 32 weeks of age were used and equally assigned into two dietary treatments having six replicates of 15 hens and two cocks each. The dietary treatments were basal diet supplemented with 0% MELM and basal diet supplemented with the MELM group (5% MELM). Data were collected on feed intake, egg production, feed conversion ratio as well as egg quality indices during the experiment. The blood samples were collected from 18 birds per treatment (three3 per replication) for the determination of total protein, uric acid, triglycerides and total cholesterol at 45th week of age.
The results showed that there was no significant difference on the feed intake of the birds across the treatments. Average egg weight and egg production were higher with a lower (p < 0.05) feed conversion rate in the MELM group hens. Total protein, uric acids, total cholesterol and triglyceride level increased significantly (p < 0.05) in hens fed 5 % of MELM. The proportions of yolk, egg shell and Haugh unit showed no significant difference between the treatments, while the proportion of albumen and yolk colour increased significantly (p < 0.05) in the MELM group hens.
It was concluded that 5% MELM can be used as feed ingredients in formulating breeder hen diets to improve productive performance.
世界人口不断增加,导致人类和动物对农产品的竞争加剧。人们越来越多地探索在禽类饲料中使用非常规资源。木薯(Manihot esculenta)已在蛋鸡和肉鸡饲料中进行了研究。然而,关于其叶片对种母鸡的影响的信息却很少。
本研究旨在确定木薯叶粉(MELM)对种母鸡生产性能、种蛋品质和血液参数的影响。
试验选用 32 周龄的 180 只母鸡和 24 只 Sasso 公鸡,分为两组日粮处理,每组设 6 个重复,每个重复 15 只母鸡和 2 只公鸡。日粮处理为基础日粮添加 0% MELM 和基础日粮添加 MELM 组(5% MELM)。试验期间收集饲料摄入量、产蛋率、饲料转化率以及蛋品质指标的数据。在第 45 周龄时,从每个处理组采集 18 只鸡(每个重复 3 只)的血液样本,用于测定总蛋白、尿酸、甘油三酯和总胆固醇。
结果表明,各组鸡的采食量无显著差异。MELM 组母鸡的平均蛋重和产蛋率较高,饲料转化率较低(p < 0.05)。5% MELM 组母鸡的总蛋白、尿酸、总胆固醇和甘油三酯水平显著升高(p < 0.05)。蛋黄、蛋壳和哈夫单位的比例在各组之间无显著差异,而蛋白和蛋黄颜色的比例在 MELM 组母鸡中显著增加(p < 0.05)。
结论是,5%的 MELM 可以作为种母鸡饲料配方中的饲料成分,以提高生产性能。
