“…Therefore, the results from the study suggest that addition of taro leaf up to 7% did not affect the fat content highly. The result of the present study was agreed with the reports of different researchers who reported ether extract content ranged from 4.22 to 4.98 leaf meals made of moringa, cassava and prosopis for chicken ration [14,[20][21][22].…”

“…From the present study, the ration containing TL had a better total phenols and lower anti-nutritional contents of oxalate, tannin and phytate. This could imply that the inclusion of TL in the ration may not hamper the feed intake and feed utilization of birds for appreciated growth rate because of lower anti-nutritional factors and better nutrient promoting factors such as phenolic substance [21]. In animal feeds the presence of high anti-nutritional factors can decrease feed intake and acceptability of feed nutrients which resulted in poor growth [36,37] Nworgu.…”

Introduction: the high cost of cereals and protein supplements and uncertainty about their sustainable supply for poultry pressed the need to search for other potential non-conventional feed sources which are relatively less used for human consumption. For stopping this problem the inclusion of taro leaf meals in poultry ration may supply high nutrients for the consumers because taro is multipurpose crop for food and feed sources. Taro leaf is rich in proteins and can be of supplementary protein, carotene and trace minerals in chicken diets. To achieve maximum efficiency in meat quality and production, properly balanced ration is a pre-requisite and taro could be possible alternative feed ingredients in this study.Objective: This study was conducted to evaluate the feeding value of taro leaf in broiler rations which was conducted at Debre Zeit Agricultural Research Center. Method and analysis:The study was carried out using four treatments in which the treatments were inclusion of TL at 0% (T1), 3% (T2), 5% (T3) and 7% (T4). The analysis undertaken in this study was feed DM, Crude Fiber (CF), Total Ash (TA), Ether Extract (EE), Crude Protein (CP) and functional properties (WHC, WA, WSI and WAI) of feed offered. The nutritional composition of chicken meat and cost benefit analysis were also evaluated to see the overall benefit of feeding taro. A total of eighty day-old Cobb500 broiler chicks were used for the study and lasted 56 days. At the end of the experiment, four birds were randomly taken from each pen and slaughtered for nutrient composition and protein quality analysis. Results:The result obtained from the study shows that variability was found as taro leaf level increase and from cost and benefit analyses of the study, taro leaf meal is cost effective meal when used as replacement of expensive and conventional meal in broilers rations Conclusion: Therefore, the present study encourage using taro leaf meal as a good source of nutrients for broilers like other tropical leaves

“…This is an indication of their potential usefulness as binding agents in various foods and baked products (Dairo et al, 2007). Also, high oil absorption capacities translate to high oil stability index (Mutayoba et al, 2011) which indicate their potential for use as agents in food and feed formulation. Abligos (1996) utilized Moringa oleifera in flat noodle production.…”

The potentials of Moringa oleifera leaf meal (MLM) as an alternative protein source for livestock in the tropical rainforest of Nigeria was evaluated in comparison with Leucaena leucocephala and Gliricidia sepium leaf meals (LLM and GLM respectively). Proximate analysis, mineral constituents, antinutritional factors and some functional properties were considered in this concern. The three tested leaf meals contain comparable crude protein levels at 22.23+0.25g100g -1 DM, 27.31g100g -1 DM and 25.03g100g -1 DM for MLM, LLM and GLM respectively, which are higher than 20% quoted as being common for Multipurpose trees(MPTS). The tested leaf meals had similar ash contents and sufficient levels of Ca, Na,Fe, K and Mg while the high EE content shows that they can be classified as oil rich plants. Pb was absent in all the leaf under investigation. Tannin content was low (3.51mg g -1 in GLM to 3.79mg g -1 in LLM), however, Phytic acid was highest in GLM.Lignin, cellulose and hemicellulose were low. The capacities of water and oil absorption (WAC & OAC), foaming and emulsion capacities (FC & EC) and emulsion stability (ES) were similar in MLM and LLM while GLM recorded slightly higher values. The three tested leaf meals recorded 2% least gelation concentration while iso-electric points were at pH 4, 6 and 10 indicating solubility in acidic and basic regions.These leaf meals are sources of vegetable protein for all classes of livestock and can be presented in the form of multinutrient blocks, pelleted feeds and stabilizing agents on foods.

“…Increasingly the deficit of traditional ingredients such as soyabean (Martens, Temann, Bendelle, Peters, & Lascano, 2012;Mutayoba, Dierenfed, Mercedes, Frances, & Knight, 2011), increasing trends of severe droughts (Sheffield & Wood, 2010) and competition for feed resources between humans and chickens (Ncube, Hamudikuwanda, & Banda, 2012a) continue to be blamed for high cost of poultry feeds. This has come to the attention of scientist, thus the search for alternative protein poultry ingredients and especially those from drought tolerant plants also not attracting competition between people and animals.…”

The effect of A. angustissima leaf meal based diets on intestinal physiology and dressed carcass weight was investigated on 150 day old chicks. Three diets, 0, 5 and 10% A. angustissima were used in a three phase feeding programme. At days 14, 28 and 42, two birds from each replicate were slaughtered, dressed and weighed. The weights and lengths of the duodenum, jejunum and colon were measured. Approximately 1 cm specimen was taken from each organ, fixed in formalin and stained for histological analysis. Using a light microscopy, the digestive and absorptive properties of the tissues were assessed. Inclusion of A. angustissima leaf meal increased intestinal wall thickness, epithelial thickness, and villus height of the duodenum (P < 0.05). There was no effect on the proportional weight and length of the jejunum, jejunum villi height and villi width (P > 0.05) but jejunum wall thickness decreased with increasing levels of the leaf meal (P < 0.05). Leaf meal inclusion resulted in an increase in weight, intestinal wall and mucosal thickness of the colon (P < 0.05) and a decline in sub-mucosal fold height and haustra coli width of the colon (P < 0.05). Dressed weight was the same across diets at two weeks (P > 0.05). At four and six weeks, broilers on the control and 5% diet had superior dressed weights to the 10% fed broilers (P < 0.05). It was concluded that for intestinal physiological adaptation that will not compromise weight gain in broilers, up to 5% A. angustissima could be included in broiler diets.
