Abstract
Mango seeds, which are not consumed by human beings, are a potential feed ingredient, a good source of soluble carbohydrate, protein, and higher fat than corn. This present study objectivewas conducted to examine the effect of replacing yellow corn with mango seed soaked in water (MSSW) in the formulated concentrate mixtures and experimental diets on in vitro gas production and ruminal fermentation. Four formulated concentrate mixtures consisted of 0, 20, 40 and 60% MSSW, referred to as T0, T20, T40 and T60, respectively. The experimental diets consist of the previous concentrated mixtures with Egyptian clover hay (CH) and/or wheat straw (WS), T0+CH, T0+WS, T20+CH, T20+WS, T40+CH, T40+WS, T60+CH and T60+WS, respectively. The effects of replacement were assessed by incubation of the tested substrates in buffered rumen fluid using an in vitro gas production technique, Metabolizable energy, net energy lactation, total digestible nutrientsand organic matter digestibility (OMD) were calculated from gas production after 24-h incubation. Microbial protein was calculated from OMD. Methane emissionwas high for T60 and T60+WS compared with other tested substrates. In conclusion, the results revealed that replacing up to 60% of corn with MSSW as an alternative energy source could be useful in ruminants feeds.
