Performance, Intestinal Morphology and Microbiology of Broiler Chickens Fed Egg Powder in the Starter Diet

Abstract

The effect of egg powder inclusion in the pre-starter diet (1-7 days of age) on the performance, and intestinal morphology and microbiology of male broiler chickens was evaluated in a completely randomized design. Starter diets with equal metabolizable energy and crude protein levels were formulated to contain 0, 20, 40, or 60 g egg powder/kg diet. Results showed that body weight, feed intake, feed conversion ratio, and European efficiency index were positively affected (p≤0.05) by egg powder inclusion in the starter diet. Inclusion of 40 g egg powder/kg diet in the starter diet promoted the best performance results. Jejunal villus height and villus to crypt ratio increased (p≤0.05) and intestinal length decreased (p≤0.05) as a result of egg powder inclusion in the starter diet. Egg powder inclusion in the starter diet reduced (p≤0.05E. coli counts, but increased (p≤0.05) lactic acid bacteria counts in the small intestine. The results obtained in the present study indicate that the inclusion of 40 60 g egg powder/kg of starter diet g improved the performance and intestinal health of broilers.

Infertile egg powder improves nutrient digestibility, digestive organ development, and performance of broiler chickens

“…Esmailzadeh et al (2013) suggested that poultry could consume IEP e ciently because of its highly digestible nutrient content. Previous studies also suggested that IEP supports digestive tract development, as indicated by a higher villus and a longer intestine, which increases nutrient absorption in the small intestine (Esmailzadeh et al, 2016). The improvement in digestive organ development in this study, as indicated by the heavier and longer digestive organs (Table 6), was associated with an improvement in the intact gut area for nutrient absorption, leading to greater nutrient digestibility (Ratriyanto and Prastowo, 2019).…”

“…This study has shown that dietary IEP improves digestive organ development, as demonstrated by the larger liver, gizzard, and small intestine weights, as well as small intestine lengths. Dietary IEP also provides good nutritional content for supporting digestive tract development, as has been observed previously; digestible nutrients are necessary for supporting digestive tract development and growth in broiler chickens (Esmailzadeh et al, 2016).…”

“…Processing infertile eggs from hatchery into IEP is economically relevant to reducing feed costs in broiler chickens. The high nutrient density of IEP could potentially support the growth of the digestive tract and other organs (Esmailzadeh et al, 2016), ultimately supporting growth in all parts of the body, including the muscles, skeleton, and immune system (Lei and Kim, 2013;Esmailzadeh et al, 2016).…”

Effect of Adding Whole Dried Egg Powder in the Diet on Broiler Live Growth Performance

“…Several experiments were conducted to study the effect of dried eggs in broiler diets to improve productive performance. [9], used dried eggs at the ratios of 0, 20, 40 and 60 g dried eggs/ Kg feed in broiler diets and it led to improving and developing productive performance. Moreover, [10], reported that by introducing dried eggs at a rate of 0,1,2 and 3% in diets led to an improvement in the growth performance of studied broiler.…”

Small Intestine Characteristics and Nutrient Retention in Broiler Chickens Submitted to Different Protein Regimes and Betaine Supplementation

“…The development of the digestive tract is an important factor that determines the growth performance and health of broiler chickens (Esmailzadeh et al, 2016) and affects the microbial population, which has important role in nutrient digestion and the immune system (Esmailzadeh et al, 2016;Ratriyanto and Mosenthin, 2018). Furthermore, the dietary protein level has an impact on the growth rate of the chickens (De Faria Filho et al, 2007;Moosavi et al, 2012).…”
