Effects of dietary Korean garlic extract aged byLeuconostoc mesenteroidesKCCM35046 on growth performance, digestibility, blood profiles, gas emissions, and microbiota in weanling pigs

Abstract

A total of 150 crossbred pigs [(Duroc × Yorkshire) × Landrace; body weight (BW) = 5.74 ± 1.15 kg; weaned at day 21 after birth] were assigned to one of five dietary treatments (six pens per treatment and five pigs per pen) by BW and sex (two barrows and three gilts) for a 6 wk experiment. The pen was considered the experimental unit in the statistical model. Treatments were corn–soybean meal diets supplemented with 0.0033% tiamulin as well as 0%, 0.05%, 0.10%, or 0.20% fermented garlic (FG). The average daily gain, average daily feed intake (ADFI), and feed conversion ratio were linearly (p < 0.05) increased by FG inclusion during days 21–42 and days 0–42. Dietary supplementation of FG linearly increased (p < 0.05) the coefficient of apparent total tract digestibility of dry matter, nitrogen, and gross energy as well as blood immunoglobulin G concentration during week 6. The fecal ammonia (NH3), total mercaptan emissions, and Escherichia coli counts were linearly (p < 0.05) reduced by FG in the diet. Dietary supplementation of FG increased (p < 0.05) ADFI during days 21–42 and days 0–42 and reduced (p < 0.05) fecal NH3 emissions compared with pigs fed tiamulin. In conclusion, the results indicate that FG can enhance growth performance and digestibility, and reduce fecal E. coli counts as well as fecal gas emissions in weanling pigs.

Effects of Dietary Supplementation of Garlic and Oregano Essential Oil on Biomarkers of Oxidative Status, Stress and Inflammation in Postweaning Piglets

“…These results would be in line with the better results of the oxidative stress biomarkers, cortisol and CRP in the groups supplemented with low doses of OEO and garlic. Positive effects on ADG and average daily feed intake (ADFI) when low doses of fermented garlic were given to piglets have been described [ 76 , 77 ]. In addition, improved body weight due to supplementation of garlic or garlic-derived products in pigs has also been reported [ 39 , 41 , 78 ].…”

The nutritional applications of garlic (Allium sativum) as natural feed additives in animals

“…Garlic and allicin have been used to improve health and performance in livestock production ( Cho, Liu & Kim, 2020 ). The gut development and BWG of piglet were significantly improved with the supplementation of 10 ml/100 kg body weight aged garlic extract compared with the non-garlic treatment ( Tatara et al, 2005 ).…”

Oregano Essential Oil and Purple Garlic Powder Effects on Intestinal Health, Microbiota Indicators and Antimicrobial Resistance as Feed Additives in Weaning Piglets

“…This decrease or absence of pathogenic species in the microbiota of cattle means that its use can be considered in the future as an effective alternative in the prevention of some bacterial diseases. In addition, garlic can enhance the cellular and humoral response of the immune system by stimulating various cells or mechanisms [ 62 ]. It should be noted that various scientific investigations show that garlic extract improves the digestibility of nutrients in broilers and increases feed intake in lactating pigs.…”
