“…Phytogenic feed additives are known for their essential oil, phenols, and flavonoids. However, phytogenic feed additives can bring different impacts on animal production, depending on their compositions, sources, and doses (Seok et al 2021). Flavonoid-rich different phytogenic feed additives showed a positive influence on growth performance, nutrient digestibility, antioxidant and immune status, and intestinal microbes in broilers (Kim et al 2016;Omar et al 2020;Adeyami et al 2021).…”

This study aimed to evaluate the effect of flavonoid supplementation to a low protein diet on growth performance, nutrient digestibility, excreta bacterial count and excreta gas emission of broilers. In total 800 one-day-old, Ross 308 broilers (BW; 42.90±1.43 g) were randomly sorted into one of the four dietary treatments (10 pens/treatment; 20 birds/pen). Treatment diets were HCP (High protein diet), basal diet; LCP (Low protein diet), basal diet – 2.5% protein; TRT1, LCP + 0.025% quercetin; TRT2, LCP + 0.050% quercetin. Experimental diets were provided to broilers from days 8 to 35. HCP, TRT1, TRT2 showed higher body weight gain (BWG) than the LCP group during days 8 to 21, and in the overall experiment. However, feed conversion ratio (FCR) of HCP group was improved than the LCP group during days 8 to 21 and in overall period. Increasing level of quercetin supplementations brought a linear increase in BWG. Lactobacillus, E. coli and Salmonella counts in excreta samples of experimental groups showed no significant difference. Flavonoid supplementation (0.050%) reduced drip loss in breast muscle than the LCP group and showed a linear reduction. Through improved digestion, quercetin addition to a low-protein diet reversed the body weight gain.

“…Phytogenic feed additives can affect animal productivity in a variety of ways based on their components, sources and dosages (Seok et al, 2021). The dietary incorporation of QS (0%–0.06%) improved the broiler growth performance of BWG and FI, while FCR did not differ significantly (Dang et al, 2022).…”

Quercetin (a predominant flavonoid) is considered to have antimicrobial and antioxidant properties. This trial was conducted to evaluate the impact of graded doses of quercetin (QS) on growth efficiency, nutrient retention, faecal score, footpad lesion score, tibia ash and meat quality. In a 32‐day feeding test, a total of 576 1‐day‐old Ross 308 broilers (male) were allocated arbitrarily with an average body weight of 41 ± 0.5 g. The trial had four dietary treatments with eight repetitions of 18 birds per pen and a basal diet incorporating 0%, 0.02%, 0.04% and 0.06% of QS. As the QS dosage increased, body weight gain tended to increase linearly on Days 9–21 (p = 0.069) and overall period (p = 0.079). Similarly, feed intake increased (p = 0.009) linearly with the increasing doses of QS on Days 9–21. Likewise, there was a linear improvement in dry matter (p = 0.002) and energy (p = 0.016) digestibility after QS administration. Moreover, the inclusion of QS supplement (0%–0.06%) linearly increased (p = 0.012) tibia ash in broilers. However, the faecal score and footpad lesion score showed no significant outcome (p > 0.05). By giving broilers a graded amount of QS, the relative organ weights of breast muscle (p = 0.009) and spleen (p = 0.006) improved linearly, meat colour lightness increased (p = 0.015), redness tended to improve (p = 0.065) linearly and drip loss decreased (p = 0.015) linearly. The inclusion of QS in the graded‐level diet led to improvements in growth efficiency, nutrient absorption, meat quality and tibia ash, which recommended it as a beneficial feed additive for the broiler.

“…Pinus koraiensis extracts have been explored in laying hens for improved egg production and weaning pigs for greater ADG and gain‐to‐feed ratio (Kim et al, 2018; Seok et al, 2021). This was the first try to explore the effects of PO on lactating sows and their offspring.…”

Pinecone oil (PO) of Pinus koraiensis mainly contains α‐pinene, β‐pinene, and limonene that may ameliorate animal well‐being and growth performance. This study evaluated its effects on feed intake, milk composition and yield, serum parameters, and litter growth of sows. Twenty‐seven pregnant sows (parity 2–4) were distributed to three dietary treatments. The trial started on Day 107 of gestation and ended on Day 21 of lactation. Sows were given either a basal diet or the basal diet + 200 or 400 mg/kg PO. Each treatment contained nine sows and each sow was considered an experimental unit. Results showed that the average daily gain and weaned body weight of piglets from the sows fed 400 mg/kg PO supplements were higher (p < 0.05) than the piglets from the control sows. Lactose content in colostrum samples and fat content in milk samples were higher (p < 0.05) in 400 mg/kg PO‐treated sows, respectively, than those from the sows fed basal diet. Additionally, cortisol concentration and aspartate aminotransferase concentration in sow serum was lowered (p < 0.05) by 400 mg/kg PO on Day 21 of lactation. In conclusion, supplementation of 400 mg/kg PO during late gestation and lactation contributed to greater offspring growth performance, possibly by enhanced milk quality and alleviated maternal stress.
