Study of the impact of various stocking densities on the performance, health and welfare of turkey broilers and heavy turkeys


Principal Investigator

Year the work was done

2015-2018

Overall objective

  • To determine the impact that increasing graded levels of stocking density have on various parameters (productivity, health and welfare, and behaviour) of turkey production.

Outcomes

  • Higher stocking density was associated with decreased body weight and increased food to gain ratio, but not the overall feed consumption, body weight uniformity or mortality.
  • Feather condition and cleanliness were poorer with higher stocking densities, as were fait and footpad lesion scores at 16 weeks, but stocking density did not affect injuries from aggressive pecking.

Application

  • The results of this research provides strong evidence with regards to what impacts various stocking densities have on commercial turkeys.
  • High stocking density negatively impacted performance, health, and welfare of the birds however, low stocking density also had some negative effects on bird well-being, suggesting that moderate densities may be more suitable for commercial practices.
