单色绿光补光对泰州鹅体重、屠宰性能、肉品质和血清生化指标的影响OA
Effects of monochromatic green light supplemental illumination on body weight,slaughter performance,meat quality and serum biochemical parameters of Taizhou geese
旨在研究单色绿光补光对泰州肉鹅生长性能、屠宰性能、肉品质和血清生化指标的影响.将400 只 1 日龄泰州鹅母雏随机分为2 组,每组5 个重复,每个重复 40 只雏鹅,将2 组雏鹅分别置于结构相同的半开放舍内养殖,采用自然光照加人工补光,人工补光分别采用 LED 白光(对照组)和绿光(试验组),2 组光照强度均为 40 lx,1～7 日龄采用24 h 光照(24L:0D),8～15 日龄的光照时间每天减少 1 h,16～70 日龄采用16 h 光照(16L:8D).结果:绿光补光极显著提升肉鹅在 35～55 日龄的体重(P＜0.01),在65～70 日龄增速减低,但仍显著高于白光补光(P＜0.05);绿光组肉鹅胸肌重显著高于白光组(P＜0.05),2 组间屠宰率、全净膛率、半净膛率、腿肌重、胸肌率和腿肌率等指标差异不显著(P＞0.05);绿光补光可以改善红度(a*)值(P＜0.05),但也显著增加肌肉剪切力(P＜0.05);绿光补光显著提升血清中甘油三酯(TG)含量(P＜0.05).综上,绿光补光可以促进肉鹅的生长,改善屠体鹅肉可利用率,对肉品质的改善还需进一步验证.
To investigate the effects of monochromatic green light supplemental lighting on the growth performance,slaughter performance,meat quality,and serum biochemical indicators of Taizhou geese,400 one-day-old female Taizhou geese were randomly divided into two groups,with five replicates per group and 40 goslings per replicate.The two groups of goslings were raised in semi-open sheds with identical structures,using natural light plus artificial lighting.For artificial lighting,LED white light(the control group)and green light(the experi-mental group)were used,respectively.The light intensity for both groups was 40 lx.When the geese were 1 to 7 days old,24 hours of light(24L:0D)was used;and when they were 8 to 15 days old,the light duration was reduced by 1 hour per day.When they were 16 to 70 days old,16 hours of light(16L:8D)was used.The results showed that green light supplemental lighting significantly increased the body weight of the geese aged 35-55 days(P＜0.01),with a slower growth rate at 65-70 days,but it was still significantly higher than that of the geese under white light supplemental lighting(P＜0.05).The breast muscle weight of the geese in the green light group was significantly higher than that in the white light group(P＜0.05).However,there were no significant differences between the two groups in dressing percentage,eviscerated percentage,semi-eviscerated percentage,leg muscle weight,breast muscle percentage,and leg muscle percentage(P＞0.05).Green light supplemental lighting improved the redness(a*)value(P＜0.05),but also significantly increased the muscle shear force(P＜0.05).Green light supplemental lighting significantly increased the serum triglyceride(TG)levels(P＜0.05).This study indicated that green light supplemental lighting promoted the growth of geese,improved the usability of slaughtered goose meat,and might promote fat stor-age in their liver.Further verification would be needed regarding the effect of this supplemental lighting on meat quality improvement in Taizhou geese.
