A Preliminary Study on Effects of Fermented Feed Supplementation on Growth Performance, Carcass Characteristics, and Meat Quality of Hanwoo Steers during the Early and Late Fattening Period

Abstract

The present study was conducted to determine the effects of formulated feed (IRG: Italian ryegrass, WCC: whole crop corn, and fermented feed) on growth performance, carcass characteristics, and meat quality of Hanwoo steers during early and late fattening periods. Twelve Hanwoo steers were randomly assigned into two groups: control and treatment (n = 6/group). The control group received rice straw with concentrate; the Treatment group received formulated feed for 13 months. Results revealed that formulated feed supplementation significantly (p < 0.05) increased effects on dry matter (DM) intake, body weight, average daily gain, and carcass yield than control feed. Hanwoo steers fed formulated feed showed higher meat quality, carcass yield, and ribeye area than steers fed control feed. However, meat quality characteristics (such as cooking loss, fat thickness, marbling score, meat color, and crude fat), sensory characteristics, and pH values were similar between the two groups (all p > 0.05). There was no significant difference in FA compositions of steers between the two groups (p > 0.05). Overall, these results indicate that feeding Hanwoo steers with formulated feed can improve their growth efficacy, carcass yield, and meat quality characteristics during early and late fattening periods. Regarding an economic strategy, our research findings suggest that formulated feed is effective and profitable for feeding Hanwoo steers during early and late fattening periods without causing adverse effects.

Effects of Cattle Breeds and Dietary Energy Density on Intake, Growth, Carcass, and Meat Quality under Thai Feedlot Management System

“…The energy requirement of dairy breed animals, e.g., Holstein Friesian in this study, relative to their weight, is expected to be high because they have more active internal organs and fat depots necessary to sustain their milk production than dairy cows [1]. In addition, other studies have reported that daily weight gain decreased in the late fattening stage even though feed and energy intake is like those in the early fattening stage because they require higher maintenance energy during the late fattening stage [19,28]. Previously, no significant difference in daily gain in dairy on beef crossbred compared with purebred Holsteins [1,11] was reported.…”

Effect of Fermented Concentrate on Growth Performance of Brahman Crossbred Steers: A Preliminary Study

“…The number of duplicates had a practical effect on inference errors in analyzing differences of means or variances [20]. In the Independent sample t-test, the minimum number of replications used was six replications [4,21]. In contrast, for a large number of replications, Fauzyah et al [22] and Chang et al [23] used 18 and 50 replications, respectively.…”

“…One of the feed technology methods that can improve cattle performance is by using fermentation. It is a process that is essential in the usage of prospective nutrients in maximizing their conservation and minimizing antinutritional compounds in the feed process [4]. The fermentation technique can inhibit microbial pathogens' growth and increase concentrates' nutrient quality [5,6].…”

Effect of Lupin Supplementation on the Growth, Carcass, and Meat Characteristics of Late-Fattening Hanwoo Steers

“…Recent studies have focused on developing feeds with high-energy and high-protein content to decrease beef production costs in Korea by shortening the raising period of Hanwoo steers [1,2]. The protein content of lupin has been reported to vary between 32% to 55%, depending on the processing method [3][4][5].…”
