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.

Project description:Background and aimsViny species are among the most serious invasive plants, and better knowledge of how vines grow to dominate landscapes is needed. Patches may contain a single genotype (i.e. genet), a competitively dominant genet or many independent but interacting genets, yet the clonal structure of vining species is often not apparent. Molecular markers can discriminate among the genetic identities of entwined vines to reveal the number and spatial distribution of genets. This study investigated how genets are spatially distributed within and among discrete patches of the invasive vine kudzu, Pueraria montana var. lobata, in the United States. It was expected that ramets of genets would be spatially clustered within patches, and that an increase in the number of genets within a patch would be associated with a decrease in the average size of each genet.MethodsSix discrete kudzu patches were sampled across 2 years, and 1257 samples were genotyped at 21 polymorphic allozyme loci. Variation in genotypic and genetic diversity among patches was quantified and patterns of genet interdigitation were analysed.Key resultsSubstantial genotypic and genetic variation occurred within and among patches. As few as ten overlapping genets spanned up to 68?m(2) in one patch, while >90 % of samples were genetically unique in another patch. Genotypic diversity within patches increased as mean clone size decreased, although spatially widespread genets did not preclude interdigitation. Eight genets were shared across ?2 patches, suggesting that vegetative dispersal can occur among patches.ConclusionsGenetically unique kudzu vines are highly interdigitated. Multiple vegetative propagules have become established in spatially discrete patches, probably through the movement of highway construction or maintenance machinery. The results suggest that common methods for controlling invasive vines (e.g. mowing) may inadvertently increase genotypic diversity. Thus, understanding vine architecture and growth has practical implications.

Project description:BackgroundIn collaboration with the Office of Dietary Supplements at the National Institutes of Health, the National Institute of Standards and Technology issued a suite of botanical matrix reference materials (RMs) and Standard Reference Material® (SRM) for determination of isoflavones and toxic elements in kudzu dietary supplement ingredients.ObjectiveRM 8650 Pueraria montana var. lobata (Kudzu) Rhizome, SRM 3268 Pueraria montana var. lobata (Kudzu) Extract, and RM 8652 Kudzu-Containing Solid Oral Dosage Form were issued with values assigned for isoflavones (puerarin, daidzin, and daidzein), toxic elements (arsenic, cadmium, and lead), and selenium.MethodsIsoflavone values were assigned using liquid chromatography with UV absorbance or mass spectrometry detection. Element values were assigned using inductively coupled plasma mass spectrometry and results from an interlaboratory comparison exercise.ResultsMass fractions for puerarin were 32.2 ± 3.2 mg/g, 128 ± 13 mg/g, and 68.2 ± 6.9 mg/g in RM 8650, SRM 3268, and RM 8652, respectively. Arsenic increases from 156 ± 14 ng/g to 849 ± 83 ng/g and cadmium decreases from 348 ± 14 ng/g to 82.1 ± 4.9 ng/g from rhizome to extract.ConclusionThe kudzu RM/SRM suite complements previously issued soy-related SRMs with values assigned for isoflavones, which have been studied for their potential health benefits, and expands the analytical resource by providing values for puerarin, an isoflavone not found in soy.HighlightsThe three new kudzurmaterials are for use in the determination of isoflavones, toxic elements, and selenium. For the isoflavones, these new kudzu materials provide higher levels of daidzin and daidzein than existing soy-related SRMs, and they provide a value for an isoflavone not in existing SRMs (puerarin). Toxic elements in RM 8650 and SRM 3268 provide new botanical matrixes for use by dietary supplement manufacturers for the verification of the safety of their raw materials.
