Abstract
The aim of this study was to evaluate the effects of incorporating Bacillus spp.-fermented mixture (FM; 55% soybean meal and 45% feather meal) in the starter feed of goat kids, specifically its effects on growth performance, blood profile, carcass characteristics, and gastrointestinal traits; the FM protein profile was also evaluated. Seventy-five four-week-old male dairy goat kids were randomly assigned to three different starter diet groups containing B, D, or J strains of 5% Bacillus spp. FM (BG, DG, and [...]
Highlights
The starter diet is essential for development during the transition period from liquid to solid feed; starter feeds are formulated to promote animal growth and health (Senevirathne et al, 2017)

Using a suitable Bacillus sp. to ferment soybean and feather meals can increase the available nutrients. These results indicate that adding 5% Bacillus spp.-fermented soybean and feather meal mixture to a starter feed is a feasible option to improve the growth performance of goat kids, without negatively impacting their health
Summary
The starter diet is essential for development during the transition period from liquid (colostrum, milk, or milk replacer) to solid feed (forage or concentrate); starter feeds are formulated to promote animal growth and health (Senevirathne et al, 2017). Animal protein, feather meal, has been increasingly used in animal feeds. Feather meal is a byproduct of the poultry industry, containing lipids (12-15%) and protein (58-65%), in Taiwan, it is only incorporated in ~5% of feed products (Dawood et al, 2020). This is largely due to its low digestibility and biological value, as well as deficiencies in essential amino acids, challenges that must be addressed prior to its use in animal feed (Onifade et al, 1998)
