Fıstık Kabuğu, Nar Kabuğu ve Zeytin Pirinasının Koyunlarda Süt Verimi, Süt Kalitesi ve Bazı Kan Biyokimyasal Parametreleri Üzerine Etkisi

Abstract

Feeding significantly affects the composition of sheep milk, thus making milk more suitable for human consumption. Different feeding programs can cause significant changes in milk yield and milk quality parameters. This study was carried out to determine different ways to use industrial waste obtained from pistachio, pomegranate, and olive fruits as alternative feed sources for sheep. In this study, 52 sheep (n=13 for each group) aged 3 and 4 years were included. Sheep were divided into four groups with respect to age, birth type, milk yield, and lactation period: control (CON) diet without added byproducts and feed containing pistachio shell (PIS), pomegranate hull (POM), and olive pulp (OP). The highest values in terms of milk yield detected in the POM group in the first, second, and third periods were 1142.80±110.74, 966.76±127.10, and 784.76±111.99, respectively; similar values were found in the other groups (P>0.05). As a result, there was no significant difference among the groups in terms of feed consumption. The highest fat rate in the study was 6.86±0.45% in the PIS group in the 2nd period, and the highest protein ratio was determined as 6.39±0.19% in the OP group in the 3rd period. There was no statistically significant difference among CON, PIS, POM and OP groups in terms of biochemical parameters. According to the findings of this study PIS, POM and OP added to sheep rations at a rate of 5% can be considered as alternative feed sources without causing a significant decline in milk yield and health parameters.
