Effects of garlic supplementation on energy status of pre-partum Mahabadi goats
Journal Title: Veterinary Research Forum - Year 2014, Vol 5, Issue 3
Abstract
To evaluate the effects of garlic on some blood metabolites in pre-partum dairy goats, the ration was supplemented with raw garlic at the doses of 0, 30, 50 and 70 g kg-1 of Dry matter (DM) in eight pregnant Mahabadi breed goats (59 ± 1 kg initial live weight) in a replicated Latin square design during the last two months of pregnancy. Each experimental period lasted 14 days with the first 12 days used for diet adaptation and two days of data collection with a 3-days wash-out period between treatments. The results revealed a beneficial increasing effect of garlic (at the level of 70 g kg-1 of DM) on serum glucose concentration (p < 0.05). No effects of garlic supplementation on blood non-esterified fatty acids (NEFA), β-hydroxybutyrate (BHB), total triglycerides, total protein, and albumin concentration were observed, except for serum cholesterol concentration, which was reduced (p < 0.05) with 70 g kg-1 of DM of garlic supplementation. Dry matter intake was the same between the different treatment groups and throughout the trial period. Concerning the blood indicators of negative energy balance, no significant effects were found for NEFA and BHB in pre-partum goats however, serum glucose was improved significantly, which showed that garlic supplementation may improve the efficiency of feed utilization. In conclusion, garlic, as feed additives in ruminant nutrition, holds promise for improving feed efficiency and controlling the negative energy balance.
