I. INTRODUCTIONA recent on Australian sorghum by Selle et al. (2017) that sorghum produced in Australia is used almost exclusively for feed, especially cattle, pigs and poultry. The objective of the present study is to assess the response of broiler chickens to diets based on sorghum, when supplemented with a combination of enzymes, targeting different substrates.II. MATERIALS AND METHODSA total o ...

This study was aimed at assessing endogenous enzyme activities and utilisation of metabolisable energy by broiler chickens fed maize-based diets supplemented with phytase and carbohydrases. Birds were raised in cages in climate-controlled rooms. The jejunum and pancreas were collected at 10 and 24 d for analysis of endogenous digestive enzyme activities. Birds were also sampled at hatch and 24 d a ...

I. INTRODUCTIONThe optimum utilization of nutrients, especially energy and protein, by poultry is essential in commercial production. The efficiency of feed utilization has been improved through genetic development (Rege 1994), alongside feed processing and use of feed additives, especially microbial enzymes. Energy utilization in poultry can be measured by assessing metabolizable energy or net en ...

I. INTRODUCTION The non-therapeutic use of antibiotics in animal feed has been banned in some regions of the world (Lekshmi et al. 2017) and there are restrictions on the use of some products in other countries, including Australia (APVMA, 2017). This has led to a search for alternatives to antibiotics for use in poultry production. Yeasts and their by-products have been identified as potent ...

I. INTRODUCTIONIn Tanzania, a majority of the SM farmers use mash diets for feeding broiler chickens, and this has resulted in lower performance. The feed industry in Tanzania is less developed due to lack of analytical facilities, low quality of ingredients and lack of government policy enforcement on feed quality (Geerts 2014). Improving feed quality through physical processing and microbial enz ...
