I. INTRODUCTION Flock uniformity is a key performance indicator and economic driver in commercial practice. Hughes et al. (2017) pointed out that Australian losses could exceed AUD$127M per annum, assuming that 5% of throughput totalling 1,159,602 tonnes chicken meat per annum was downgraded by 40% due to out-of-range weight specifications. From these brief comments it is easy to see that flock un ...

IntroductionWheat, maize and sorghum are the three most commonly used grains in the poultry industry worldwide (Liu et al., 2014). These cereal grains usually constitute a major proportion (60 - 70%) of the diet fed to broilers (Black et al., 2005). Although cereals represent a major source of energy for birds, there are wide variations in the energy and nutrient content of different species and c ...

BackgroundThe avian ceca generally have a more important role in digestion than the cecum in most mammals. Avian ceca are usually finger-shaped blind pouches, presenting as lateral extensions at the junction of the small and large intestine and are commonly present in pairs. In birds the ceca vary considerably in size and morphology; ranging from very long, such as in most domestic poultry, to com ...

fazal Malik Malik As I said earlier, "How long to provide probiotics after hatch is difficult to say due to lack of suitable published evidence in this area. This is a topic requiring much more research effort in my view." Which probiotics are effective is also difficult to say based on published data. As in the early days of exogenous feed enzyme usage there were many claims and also many failu ...

Rafael Duran, thanks for your interest and questions. My belief is that we need to provide probiotics no later than point of hatch, or earlier if feasible, in order to influence the development of the gut microbiota. Once this is set it is difficult, if not impossible, to alter it without continuous application of probiotics. How long to provide probiotics after hatch is difficult to say due to la ...

IntroductionA range of studies have investigated the structure of the microbiome in the gut of broiler chickens. Comparison across studies has proven difficult because of the variety of different methods used; e.g. culture based studies [1], G+C profiling analysis [2], quantitative PCR [3], and 16S rRNA based studies. The 16S-based methods have used a number of different approaches including termi ...

INTRODUCTIONThe gastrointestinal tract (GIT) microbiota of humans and animals consists of complex populations that include many different species of bacteria along with smaller numbers of fungi, protozoa, and archaea (Zoetendal et al., 2006). Over the last decade our understanding of the diverse functional roles and interactions of the GIT microbiota has rapidly advanced (Zoetendal et al., 2006). ...
