Effect of post-hatch transportation duration and parental age on broiler chicken quality, welfare, and productivity

Broiler chicks are transported to production sites within one to 2 d post-hatch. Possible effects of this transportation are poorly understood and could vary among chicks from breeder flocks of different ages. The aim of the present study was to investigate the effects of transportation duration and parental flock age on chick welfare, productivity, and quality. After hatch in a commercial hatchery, 1,620 mixed-sex chicks from 29-wk old (young) and 1,620 chicks from 60-wk old (old) breeders were subjected to transportation of 1.5 h or 11 h duration. After transportation, 2,800 chicks were divided among 100 pens, with each pen containing 28 chicks from one transportation crate (2 or 3 pens per crate). From the remaining chicks, on average 6 chicks (min 4, max 8) per crate (n = 228) were randomly selected and assessed for chick quality, weighed, and culled for yolk sac weighing (one d). Chicks that had not been assigned to pens or were not used for post-transportation measurements, were removed from the experiment (n = 212). Mortality, ADG, BW, and feed conversion (FC) of the experimental chicks were recorded until 41 d. Meat quality was measured for breast fillets (n = 47). No interaction effect of parental age and transportation duration was found for any variables. BW and yolk sac weight at one d were lower for chicks transported 11 h than 1.5 h and for chicks from young versus old breeders. The effect of parental flock age on BW persisted until slaughter. Additionally, parental age positively affected ADG until slaughter. Chick quality was lower in chicks from old versus young breeders. Chick quality and productivity were not affected by transportation duration. Mortality and meat quality were not affected by either parental age or transportation duration. To conclude, no long-term detrimental effects were found from long post-hatch transportation in chicks from young or old parent flocks. Based on these results, we suggest that 11 h post-hatch transportations under similar conditions do not impose long-term welfare or productivity risks.

How do innovation partners differ with respect to innovation type and stage in the innovation journey of farmers

The locus of innovation is the network within which a farm is embedded. This paper investigates the relationships between network partners and innovation (types and stages in the process) in agriculture, which is unique in this field. In contrast to the majority of innovation studies, the authors also include marketing and organizational innovations and investigate the need for different partners along the innovation journey. The study is based on in-depth interviews with farmers. The findings provide useful research-related and managerial implications that enable farmers and network coordinators to improve the innovation capacity in agriculture via networking. The main conclusion is that, depending on the stage in the innovation journey and the type of innovation, different resources and hence different partners are needed. Therefore, farmers must be aware of the importance of partner suitability and network heterogeneity related to the type of innovation and stage in their innovation process.

Asymmetric relationships in networked agricultural innovation processes

Purpose – In innovation networks, asymmetric relationships are both considered as an opportunity and a threat for the enhancement of innovation. The purpose of this paper is to investigate how much asymmetry Flemish farmers perceive in their relationships for innovation with colleagues, suppliers and buyers. Design/methodology/approach – In total, 86 farmers active in four different agricultural subsectors in Flanders were consulted, of which 38 via in-depth interviews and 48 in seven focus groups. Data were analysed using NVivo. Findings – The authors found that across subsectors, different players in innovation networks play different roles. Furthermore, the authors observed that the majority of farmers see their relationships more as a necessity for the farm to be able to function, than as an opportunity for innovation. If they collaborate for innovation, they often prefer symmetric relationships with similar companies on horizontal level. Vertical collaboration for innovation is not very popular in th...

Identifying key network characteristics for agricultural innovation: A multisectoral case study approach

This article identified network characteristics critical for successful agricutural innovations within networks, or a set of interrelated organizations aiming at knowledge exchange for innovations. To explore key success factors, the research questioned how networks cope with innovation characteristics and combined network characteristics with four innovation characteristics in four agricultural sub-sectors. Data were collected from in-depth interviews with farmers and network coordinators and from focus group discussions with farmers active in Flanders, the northern part of Belgium. Factors particularly helpful for success in agricultural innovation networks include numerous contacts, integration of knowledge providers in the network structure, face-to-face communication, a self-initiated coalition and surpassing innovation beyond the mere agricultural level, through collaboration with people from outside the sector. The findings are useful for academics, network coordinators and network members, possibly leading to a higher innovation performance via networking.
