Optimum Level of Cassava Pulp in Diets for Layers

An experiment was conducted to determine the optimum level of cassava pulp that can be included in layer diets without adverse effect on egg production and quality. Cassava pulp replaced maize at 0, 5, 10, 15, 20 or 30 %, with equal metabolisable energy and crude protein contents. The 30 % diet resulted in the lowest bulk density (610 g/litre). As the cassava pulp level increase in the diet, the weight of the small intestine and bursa increased (

Energy utilisation of broiler chicks on starter diets containing cassava pulp and microbial enzymes

Background: Cassava pulp (CSP) is a low-protein, high-fibre by-product of the starch industry. There is a potential for this ingredient in poultry diets if the nutritive value can be improved. Objective: To assess the energy utilisation of broiler chicks on diets containing CSP, when supplemented with microbial enzymes. ... Conclusion: Cassava pulp generally reduced the dietary AME, NEp and HP but did not adversely affect the efficiency of energy utilisation. Microbial enzyme supplementation improved these variables, some of them significantly

Not AvailableInadequate supply, exorbitant prices and diversion towards using cereal grains forbiofuel production, particularly maize, has led to a constant search for alternativeenergy sources for poultry and other non-ruminant species. The abundantavailability of cassava in certain regions makes it a good alternative to maizeand other cereal grains. Cassava root meal is rich in carbohydrate but low inprotein and all other nutrients, whereas, cassava leaf meal is a moderate sourceof protein. Results of studies to evaluate the replacement of cereals with cassavaproducts in poultry feed show wide variability due to differences in origin, variety,plant maturity at harvest, ecological conditions of plant growth and processingmethods. Cassava products contain a wide range of cyanogenetic glycosides,particularly linamarin and lotaustralin. The level of hydrocyanic acid releasedfrom the cyanogenetic glycosides limits the utilization of cassava, but with properprocessing, the dietary inclusion level of cassava meal can be increased for economicpoultry production.

Microbial Enzyme Supplementation of Broiler Chicken Diets Containing Cassava Pulp

A study was conducted to evaluate the response of broiler chickens to diet containing varying levels - 0 (Control), 100 (Low), 150 (High) g of cassava pulp (CSP)/kg diet and supplemented with exogenous microbial enzymes. Feed intake was not affected by the level of CSP in the diet but was reduced (

Variation in nutrient composition of cassava pulp and its effect on productivity of layer and broiler chickens

In a recent study at the of University of New England, Australia, a series of experiments was conducted to evaluate the nutritive value of cassava pulp (CSP) in layer and broiler chicken diets

Variation in nutrient composition of cassava pulp from Thailand

Cassava (tapioca) is a starchy tropical tuber crop that is used as an energy source in animal diets. In the regions in which it is grown, most cassava is fed to animals in the form of whole tubers. In Thailand and other parts of south-east Asia, cassava tubers are processed further into chips or pellets for local animal feeding and for export to other parts of the world, including Australia. Cassava is also used for starch production, and in Thailand more than 10 million tonnes of cassava are used for this purpose per anum. A fibrous residual material known as cassava pulp, which constitutes 30% of the mass of the original tuber, is obtained as a by product of this process. About 1.5–2.0 million tonnes of cassava pulp are produced per year. As the starch extraction process is not very efficient, the pulp contains bout 50% starch on a dry basis (Ukita et al., 2006). However, the composition of the pulp differs between regions and according to the extraction and postextraction processes used. Cassava pulp is commonly fed to ruminant animals, but its nutritive value for nonruminant species such as poultry and pigs is unclear

The Influence of an Exogenous Microbial Enzyme Supplement on Feed Consumption, Body Growth and Follicular Development of Pre-Lay Pullets on Maize-Soy Diets

An experiment was conducted to examine the benefits of supplementing maize-soy diets with a composite microbial enzyme, Allzyme SSF, for laying hens at the pullet stage. Seven hundred and twenty 12-week old Isa Brown pullets were used in the different level of protein content diets. Feed intake from 12 to 16 weeks of age was unaffected by the enzyme supplement, except at the lowest protein content (

Evaluation of Cassava Pulp as a Substitute for Maize in Poultry Diets

The aim of this project was to identify the optimum level of cassava pulp (CSP), a by-product of the cassava starch industry, which can be used in layer and broiler chicken diets. Source of cassava pulp, dietary inclusion level, and supplementation with microbial enzymes were investigated, in terms of nutritive value of the ingredient and its effect on utilization of nutrients by layers and broilers. Feeding trials on layer and broiler were conducted in Thailand in environmentally controlled housing. Each experimental chapter has been presented as a stand-alone research paper

Improving the nutritive value of alternative feed ingredients for poultry

This paper discusses the use of alternative feed ingredients in poultry nutrition. The importance and limitations, particularly the presence of anti-nutritive factors, of such ingredients are highlighted. The results of a series of studies recently completed or ongoing at the University of New England, Australia, suggest that the nutritive value of such ingredients can be improved through supplementation with microbial enzymes. As it is likely that such ingredients will be increasingly used with enzyme supplementation and other treatments, it is important to identify the anti-nutritive factors in alternative ingredients and develop the best enzyme combinations for diets that contain these ingredients
