    Abstract Two trials were conducted to determine feed color effects on broiler performance. A completely randomized design was used. Trial 1 included four treatments: control (complete broiler starter diet), red, green, and blue; and Trial 2 included four treatments: control, orange, yellow, and purple. Each trial had 4 treatments with 4 replicates (60 birds/treatment) fed to 240 male Cobb 500 broilers during a 21 d grow out. Data were analyzed using the GLM procedure. In Trial 1, there were no treatment effects on average body weight, body weight gain, and feed consumption (

    Abstract This research study was conducted to determine the effects of dietary supplementation of kudzu leaf meal (KLM) and alfalfa meal (AM) on broiler performance, carcass characteristics, and organ parameters. Kudzu leaf meal and AM were added at rates of 6% and 7.3%, respectively, to a complete broiler starter diet. Three treatments (control (complete broiler starter diet), KLM supplementation; and AM supplementation) with four replicates were fed to 217 male broilers over a 21 d battery cage grow out. Data were analyzed as a completely randomized design with battery cage representing the experimental unit. Birds on KLM and AM had a lower average body weight, lower cumulative feed consumption, and a higher adjusted feed conversion than control (

    Abstract Two trials were conducted to determine feed color effects on broiler performance. A completely randomized design was used. Trial 1 included four treatments: control (complete broiler starter diet), red, green, and blue; and Trial 2 included four treatments: control, orange, yellow, and purple. Each trial had 4 treatments with 4 replicates (60 birds/treatment) fed to 240 male Cobb 500 broilers during a 21 d grow out. Data were analyzed using the GLM procedure. In Trial 1, there were no treatment effects on average body weight, body weight gain, and feed consumption (p > 0.05). Adjusted feed conversion for control (1.23) was less than red (1.27; p = 0.001) and green (1.26; p = 0.009), with blue (1.25; p = 0.056) tending to be different during the experimental period. In Trial 2, there were no treatment effects on average body weight, feed consumption, and adjusted feed conversion during this study (p > 0.05). Body weight gain between d 1 to 14 for purple (490.78 g/bird) was more than orange (467 g/bird; p = 0.013) and yellow (461 g/bird; p= 0.004), with control (474 g/bird; p = 0.052) tending to be different. Results indicate that these feed colors had some, albeit limited, influence on broiler performance parameters.

  4. Article: Comparison of Dietary Kudzu Leaf Meal (Pueraria montana Var. lobata) and Alfalfa Meal Supplementation Effect on Broiler (Gallus gallus domesticus) Performance, Carcass Characteristics, and Organ Parameters

    Abstract This research study was conducted to determine the effects of dietary supplementation of kudzu leaf meal (KLM) and alfalfa meal (AM) on broiler performance, carcass characteristics, and organ parameters. Kudzu leaf meal and AM were added at rates of 6% and 7.3%, respectively, to a complete broiler starter diet. Three treatments (control (complete broiler starter diet), KLM supplementation; and AM supplementation) with four replicates were fed to 217 male broilers over a 21 d battery cage grow out. Data were analyzed as a completely randomized design with battery cage representing the experimental unit. Birds on KLM and AM had a lower average body weight, lower cumulative feed consumption, and a higher adjusted feed conversion than control (p < 0.05). Additionally, there were observed treatment effects on whole breast weight (p = 0.0010), with control being higher than both treated diets. Minimal treatment effects were observed for organ parameters. Furthermore, there were no observed treatment differences for mortality (p > 0.05). Although broilers on KLM did not perform as well as those in the control group, these results are indicative that kudzu is safe to use in poultry production and has a high potential as a protein supplement in tropical regions with a low availability of commercial protein feedstuffs.

    Abstract This review assesses the potential use of kudzu (Pueraria montana var. lobata) as a feedstock for livestock. Kudzu in the United States is a recognized invasive plant species that has continued to cause problems for the environment and land owners. In kudzu’s native countries, it has continued to have beneficial uses beyond being an adequate form of soil erosion control. Never the less, kudzu is a rampant weed that causes harm to many environments. In the United States, local farm owners have used ruminant species as a form of biological control to prevent the spread of kudzu and provide their animals with a high nutrition feed supplement. However, there are few reports that assess ruminal degradability in ruminants and kudzu quality. There is great potential for kudzu as a feed supplement for livestock species. Furthermore, using kudzu as a feed supplement for livestock species serves a dual-purpose of biologically controlling the spread of kudzu while providing those animals with a high-quality feedstuff.

    Abstract The present study evaluated the individual and combined effects of coated and uncoated phytase on broiler performance, tibia characteristics, and residual phytate phosphorus (P) in manure. Two repeated studies were conducted using 240-day-old Cobb 500 by-product male broilers per trial. For each trial, birds were assigned to four treatments with four replicate battery cages per treatment (60 birds/trt) and grown for 21 days. Treatments included: (1) negative control (NC), (2) NC + 1000 phytase units (FTU) coated phytase (C), (3) NC + 1000 FTU uncoated phytase (U), and (4) NC + 500 FTU coated + 500 FTU uncoated phytase (CU). Data were analyzed with a one-way ANOVA and means were separated using Tukey’s HSD. In the pooled data for both trials, all treatments with dietary phytase had a higher body weight (BW) and feed consumption (FC) than the NC on day 21 (p < 0.05). Similarly, a six-point reduction was observed for day 1 to 21 feed conversion (FCR) for U and CU (p < 0.05). All treatments with phytase inclusion differed from the NC in every evaluated parameter for bone mineralization (p < 0.05) and had significantly lower fecal phytate P concentrations compared to the NC (p < 0.05). Overall, bird performance was essentially unaffected by phytase form, indicating that combining phytase forms does not appear to offer any advantage to the evaluated parameters from day 1 to 21.
