Abstract

The aim of study to estimate the effect of adding different levels of Mango seeds kernel (MSK) to animal diets on milk production and composition and lambs growth. Twenty ewes were chosen randomly and divided into groups (5 in each) to fed four diets during feeding trial, the first diet without MSK (C) , the second (R1) contain 5% MSK, the third  (R2) contain 10% and the last one(R3) contain 20% MSK. The results showed that the lambs from mothers fed R2 resulted in a significant increase in weaning weight, growth, and daily growth rate compared to the control. On the other hand, ewes fed R2 recorded the highest actual milk, and 4% FCM yield compared to the other experimental diets and highest feed conversion and feed efficiency Fatty acids profile showed that values of saturated fatty acids decreased in R2 by 4.79% compared to control diet while the unsaturated fatty acids in R2 appeared to increase by 7.7% compared to control diet. There were no significant differences in blood measurements among experimental diets, except for cholesterol concentration, the lowest significant concentration was found when feeding in the diets R2 and R3. Therefore, it can be recommended to include the MSK in ewe's diet at a rate of 10%, with the possibility of increasing the rate to 20% without negatively affecting on the animal’s health and economic benefit from it.
