Evaluation of Cassava Peel – Cassava Leaf Meal Based Diets for Milk Production by the West African Dwarf Goats in South Eastern Nigeria

Abstract

An experiment was conducted to determine the effects of cassava peelcassava leaf meal based diets on the milk yield and composition of WAD goats. Four lactating WAD does were housed individually in pens and were assigned to the experimental diets in a 4x4 Latin Square Design Experiment and fed for 56days. Drinking water was offered liberally. Milk yield (MY) was measured and analyzed weekly for total solids (TS), butterfat (BF), crude protein (CP), solids-not-fat (SNF), lactose, ash and milk energy. MY, BF, CP, SNF, ash, milk energy, solidscorrected-milk yield (SCM) and fatcorrected-milk yield (FCM) did not differ significantly (P>0.05) among the treatment groups. Total solids and lactose were significantly (P<0.05) different among treatment groups. The group on diet B (10% cassava leaf meal (CLM)) recorded the highest total solids percentage (12.81%) while the group on diet D (30% CLM) recorded the lowest. The group on diet B also recorded the highest lactose content (4.30) while the least was recorded for the group on diet D (4.18). The relationship between MY and various milk constituents indicated negative correlation between MY and TS, MY and BF, MY and SNF, MY and lactose. However, these correlations were not significant (P>0.05). Positive correlation existed between BF and TS, milk protein and TS, milk energy and TS, lactose and SNF, milk energy and BF, BF and milk protein. Milk protein and BF were highly significant (P<0.001) and positively correlated. Milk protein and SNF were negative and significantly correlation while a significant positive correlation existed between BF and milk protein. Diet D (30% CLM) which gave the highest MY, the lowest total solids and lactose percentage is recommended.

Nutrient and Anti-Nutritional Composition of Crop Residues and Kitchen Wastes Fed to Small Ruminants in Choba, Port Harcourt

“…The crude protein of the feedstuffs in this study was higher than the crude protein reported by Babayemi et al(2010). The crude protein content of cassava leaves in this study was higher than that reported by Ukanwoko and Ibeawuchi (2014). The crude protein content reported for yam peels, cassava peels and ripe plantain peels by Kalio et al (2013) compares favourably with those reported in this study.…”

Nutrient Intake of West African Dwarf Goats Fed Dietary Models of Ensiled Cassava Peel Meal Fortified With Calcium-Phosphorus Salt

“…Dry matter content of the dietary models across the treatments ranged between 85.01% and 86.50%. This value range is comparable to 87.52% reported by Ukanwoko and Ibeawuchi [13] for cassava based diets fed to WAD goats. But lower than 90.30-91.84% reported by Guimaraes et al [14] for diets containing cassava peels fed to goats.…”

“…More so, all the diets seemed to be isoproteic due to similar values obtained. Crude fiber content obtained was higher than 16.60% reported by Ukanwoko and Ibeawuchi [13]. The values of ether extract are comparable across the dietary treatment but slightly lower than 6.04% reported by Kalio et al [16] for urea treated cassava peel fed to WAD goat.…”

Nutritional Evaluation of Cassava (Manihot esculenta) Peels as a Dietary Supplement in Tropical Friesian Holstein Cross Breed Dairy Cattle

“…However, Indonesia national minimum standard for fresh milk are fat 3%, SNF 8%, protein 2.7%, and TS 11% [7]. Unchanged milk volume on the supplementation of cassava peels, cassava leaves, and cassava roots was also reported in the studies of Petlum et al [8], Lunsin et al [9], and Ukanwoko and Ibeawuchi [10]…”
