Breeding and agronomy of novel, low-vicine faba beans and adoption as domestic protein feed (Abo-Vici)
Project
Project code: 2815EPS063, FLI-ITE-08-Br-0052
Contract period: 13.03.2017
- 31.08.2020
Budget: 30,702 Euro
Purpose of research: Applied research
Overall-objectives: to enlarge the hectarage of faba beans in Germany, as contribution to home-grown protein feed. A novel winter-type faba beans will be bred which is low in (antinutritive) vicine/convicine (V+C). Botanical, genetic, breeding and agronomy issues of V+C will be solved. Value of these beans as feed for laying hens will be evaluated. Objectives for THIS section of the project: to satisfy tasks in genetic and breeding research in the project, to provide seed for research of the other partners, to coordinate this research net, to transfer results into the community. Entire Project Coordinator Link (Göttingen). Breeding and breeding research for all partners is jointly conducted by Link & Sass (Hohenlieth). Defined faba beans will be employed, they include near-isogenic contrasts for normal vs. low vicine/convicine (V+C). Agronomy tasks (partner Schmidtke, Dresden): Map agro-meteorologically convenient sites for winterbeans; assess effect of V+C on resistance, N2-fixation and balance sheet, water uptake (incl. spring vs. winter types). Tasks in breeding and breeding research (partners Link & Sass): Development of a NIRS-calibration for V+C-breeding, breeding of a first novel low V+C-winterbean variety. Tasks in molecular genetics (partners Krzcal/Höfer, Neustadt & Link): Reference transcriptome (V+C) and candidate genes; develop SNP & fine map the V+C-locus; narrow down the list of candidate genes with bulked segregant transcriptome analyses; MACE to further narrow down the list; bioinformatics identification of the V+C-gene. Tasks to assess feedstuff value (partner Rodehutscord, Hohenheim): chemical-analytic characterization & amino acid digestibility of the novel bean types. Tasks in animal nutrition (partner Halle, Braunschweig): two performance trials with laying hens on the V+C-effect and on the maximum reasonable dose for low V+C beans in laying hens. All partners: integration & delivery of the results.
The 1st study of the project „Abo-Vici“ (FKZ: 2815EPS063) started on 9-10-2018 in the 22nd life week of the 400 Lohmann Brown (LB) hens in the experimental station of the Institute of Animal Welfare and Animal Husbandry FLI, Celle) and ended on 26-3-2019. The hens were allocated to 5 groups (80 hens per group) and kept in 4 pens per group. The 2nd study started on 30-07-2019 in the 22nd life week of the 400 LB-hens on the same place and ended on 14-01-2020. The hens were allocated to 4 groups (100 hens per group) and kept in 5 pens per group. The results of trial 1 showed, that a partial exchange of soya as the main protein source in the feed by the addition of 15% or 30% Vicin/Convicie-rich field beans particularly reduced the hens daily feed. This lower nutrient intake lead to reduced number of eggs and egg weight. The results demonstrated, by contrast, that the partial exchange of soya by the new Vicin/Convicin-poor winter field beans in hen feed (15/30%) had no negative effects on the hens´ daily feed intake as well as on laying perfomance, egg weight, feed conversion and breaking strength of egg shell. The results of trial 2 confirmed that a gradual increase (0/15/30/37%) of new Vicin/Convicin-poor winter field beans in hen feed did not significantly influence laying performance, egg weight and daily egg mass production of the hens. In these parameters the treatment grous did not difffer from the control group. Furthermore, the results indicated that soya feedstuffs used as protein source can be replaced in hen feed with a gmo-free, high protein sunflower extraction meal (HP 46) produced by a thermal pressure.
