植物精油对断奶仔猪生长性能、血液指标及免疫能力的影响
Effects of Plant Essential Oils on Growth Performance, Blood Indexes and Immune Capability of Weaning Piglets
摘要
Abstract
The objective of present study was to investigate the effects of dietary plant essential oils (PEO) on growth performance, blood indexes and immune capability of weaning piglets.Twenty-four healthy "Duroc×Landrace×Yorkshire" weaning piglets weaned at 30 days of age with similar body weight were randomly divided into 4 groups with 6 replicates per group and 1 pig per replicate.Pigs in the 4 groups were fed the basal diets supplemented with 50 mg/kg colistin sulfate (CS group) and 50 (group Ⅰ), 100 (group Ⅱ) and 200 mg/kg PEO (group Ⅲ), respectively.The preliminary period lasted for 6 days and the formal period lasted for 14 days.The results showed as follows: 1) the average daily gain (ADG) of weaning piglets in group Ⅲ was significantly higher than that in CS group (P<0.05), and it showed an increasing trend on ADG compared with group Ⅰ and group Ⅱ (P=0.05, P=0.06).The ratio of feed to gain (F/G) of weaning piglets in group Ⅲ was lower than that in other groups, but had no significant difference (P>0.05).2) The dry matter (DM) digestibility in group Ⅰ was significantly lower than that in other groups (P<0.05), the crude protein (CP) digestibility in group Ⅲ showed an increasing trend compared with group Ⅰ (P=0.07).3) The red blood cell count in group Ⅲ was significantly higher than that in CS group (P<0.05);the mean corpuscular hemoglobin concentration in group Ⅱ was significantly higher than that in CS group (P<0.05);the serum glucose content in group Ⅲ was higher than that in other groups, but had no significant difference (P>0.05);and the serum albumin content in group Ⅲ was significantly higher than that in other groups (P<0.05).4) The serum immunoglobulin G content in group Ⅲ was significantly higher than that in CS group and group Ⅰ (P<0.05), the serum immunoglobulin A content in group Ⅲ was significantly higher than that in group Ⅰ (P<0.05).In conclusion, diets supplemented with 200 mg/kg PEO has the effects for improving blood effective components content, and improve body immunity, enhancing weaned piglets health and improving growth.Therefore, the PEO has a potential value in weaning piglets.关键词
