Analysis of Marketing Performances according to Raising Environment in Broilers

Abstract

This study was conducted to investigate basic data of development for appropriate management system in broiler. Data such as ages at marketing, livability, body weight, etc. were collected from a total of 53 broiler farms located in Chungnam, Chungbuk, Jeollanam, Jeollabuk, Gyeongbuk. 1. Average of ages at marketing were 32 days. Those of windowless house and open-type house were 31.96 and 32.03 days, respectively. The significant difference among four seasons was highly found (P<0.001). The longest ages at marketing were 32.86 days in winter. Average of livability was 96.25%. According to type of chick house, those of windowless house and open-type house were 95.93% and 96.59%, respectively. The livability according to season showed significant difference (P<0.05). The highest livability was 97.39% in autumn. However, the lowest livability was 95.36% in summer. 2. Average body weight at marketing was 1.62 kg. The significant difference was found in marketing weight by season (P<0.05). The heaviest body weight was 1.65 kg in winter, but the lowest weight was 1.60 kg in summer. Average of FCR was 1.62. the significant differences according to the season were highly found (P<0.01). Especially, the best FCR was 1.59 in autumn. Average cycles of marketing was 5.70. The significant differences according to farms size were found (P<0.05), cycles of small farms and big farms were 5.8 and 5.3, respectively. The ages at marketing were highly correlated with marketing weight (r=0.684) and feed conversion (r=0.439). The correlation between feed conversion and livability was highly negative (r=-0.614). According to the above result, livability and body weight at marketing were badly detected in summer. In conclusion, broiler farms should be controlled through properly environmental management system for improvement of performances.

Global Restriction of Using Antibiotic Growth Promoters and Alternative Strategies in Poultry Production

“…Refs [99][100][101][102] Antimicrobial peptides and fermented protein Improves live performance and gut health; decreases bacterial count in the intestine; enhances immunity and nutrient utilisation.…”

“…Zhao et al 100 reported that dietary supplementation of bacteriophages significantly improved egg production of laying hens. In addition, improved body weight and feed efficiency were reported in broilers fed diets supplemented with various levels of bacteriophages 101,102 . However, further research is needed to develop practical and cost effective bacteriophage products for use in poultry production systems.…”

Carcass and retail meat cuts quality properties of broiler chicken meat based on the slaughter age

“…The Korean poultry industry has demonstrated continuous advancements regarding meat species compared to the past and significantly improved the environmental conditions and productivity indicators for broiler chickens ( Gallus gallus domesticus ). These advancements have resulted in a decreased feed conversion ratio and increased the daily weight gain, shortening the period necessary to achieve the broiler chicken market weight desired by the farms [ 1 ]. The average slaughter age of broilers was 31.8–32.8 days, and their slaughter weight was 1.68–1.74 kg between January and June 2020 in Korea [ 2 ].…”

Effects of Marketing Ages on the Physicochemical Properties and Sensory Aspects of Cured Broiler Chicken Breast Meat

“…Data are shown as means. (1) Indicated the 7-sensor array of the electronic tongue. Table 4 shows the taste score of the samples based on the electronic tongue analysis.…”

“…The poultry industry worldwide has grown significantly, and the production index of broiler chickens ( Gallus gallus domesticus ) has also improved, leading to the greatly improved daily weight gain of broiler chickens [ 1 ]. In regards to the broiler production indicators in South Korea, the average carcass weight of chickens with a marketing age of 35 day was 1.6 kg in 2011, whereas the average carcass weight of chickens with a marketing age of 34 day was 1.9 kg in 2020, which represents a clear improvement [ 2 , 3 ].…”
