IntroductionSoybean meal (SBM) is the most important and preferred source of quality protein in animal feeds (Banaszkiewicz, 2011). Among the oil seeds, SBM contains the highest crude protein (CP) and has the best AA profile, with only 6% crude fibre (Dei, 2011). The AAs in SBM are highly digestible by poultry (Newkirk, 2010). Based on the CP content, SBM can generally be classified as high protei ...

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 ...

1. IntroductionProbiotics may alter gut microflora in poultry and play a role in competitive exclusion (CE) ofSalmonella by the Nurmi concept ( Pivnick and Nurmi, 1982). Competitive exclusion involves oral administration of intestinal microflora derived from healthy salmonella-free adult birds into newly hatched chicks. Establishment of an adult intestinal microflora in newly hatched chi ...

1. IntroductionProbiotics display numerous health benefits beyond providing basic nutritional advantages. Probiotic products consisting of beneficial microflora can help to establish and maintain the balance of the intestinal microflora in commercial broilers. However, selecting a probiotic microorganism that has beneficial effects in broiler chickens requires an extensive search for the optimum c ...

1. IntroductionThe use of probiotics has become a field of science, medicine and business that is growing rapidly. In agricultural science, probiotic, prebiotics, feed enzymes and organic acids, have been seen as potential alternatives to in-feed antibiotics (IFA) (Choct, 2002). The addition of either pure Lactobacillus cultures or mixtures of lactobacilli and other bacteria to broiler ...
