Abstract
Impacts of Diets Supplemented with Green Tea By-Product on Growth Performance and Hematological Parameters in Goats
Highlights
Among the goat breed of Bangladesh, Black Bengal Goat (BBG) is the most prevalent goat breed which is famous for its high adaptability, fertility, prolificacy, delicious meat and superior skin (Devendra and Burns, 1983; Husain et al, 1996)
Hematological Parameters Blood samples were collected from the goats of treated and control group in vials containing anticoagulant (Sodium citrate 3.8 %) at day 0 of treatment period for initial screening and day 30, 60 and 90 to determine the effects of green tea by-product (GTB) on the hematological parameters namely Hemoglobin (Hb) content, Different Leukocyte Count (DLC), Total Erythrocyte Count (TEC), Albumin, Glucose, Blood Urea Nitrogen (BUN), Cholesterol, Total Protein (TP)
A finding of another study is in agreement with our results which reported that a diet supplemented with 2.0% GTB has increased weight gain of finishing pigs (Hossain et al, 2012)
Summary
Among the goat breed of Bangladesh, Black Bengal Goat (BBG) is the most prevalent goat breed which is famous for its high adaptability, fertility, prolificacy, delicious meat and superior skin (Devendra and Burns, 1983; Husain et al, 1996). Though green tea by-product (GTB) is a valuable source of protein, it can be supplemented with animal feed which would be a fruitful alternative (Kondo et al, 2004). GTB has significant effects to improve the body weight gain and feed efficiency in pigs (Hossain et al, 2012), calves (Sarker et al, 2010) and broilers (Cao et al, 2005) and it is assumed that some bioactive components of GTB (Tsuneki et al, 2004) are responsible for these outcomes Studies reported that the thiobarbituric acid-reactive substance values in raw meats can be reduced by the effect of polyphenols present in GTB (Horax et al, 2002). No study was conducted before regarding the effects of GTB in goats of Bangladesh.
