Probiotics influence mood and social behaviour, and could help manage gentle and severe feather pecking (GFP and SFP) in hens. While GFP is considered beneficial, SFP damages feather cover over time. In previous research, single-strain Lactobacillus rhamnosus reduced SFP under stressed conditions, and increased GFP overall, and multi-strain synbiotics could reduce SFP while providing other benefits. This thesis aims to as-sess the effect of a synbiotic containing Lactobacillus and Bifidobacterium on GFP, SFP, productivity, and body condition in hens.

The effects of novel Bacillus subtilis DFM (BS-9) on growth performance, indices of intestinal health, and cecal microbial composition in broiler chickens challenged with Eimeria Examining Chair: Dr. Mike Steele Advisor: Dr. Elijah Kiarie Adv.

Infection with gastrointestinal nematodes is a challenging and costly disease for sheep producers that impacts the economic efficiency of farms and reduces the welfare of infected animals. There is evidence that resistance to gastrointesti-nal nematodes is a heritable trait in sheep, and genetic selection for this trait is a novel method for Canadian sheep produc-ers to reduce levels of gastrointestinal nematode infection in their flocks.

The assessment and adequate management of transfer of passive immunity in newborn calves is dependent on various factors, with the majority of research focusing primarily on immunoglobulin G. Even though there are clear recommendations for calf rearing protocols, colostrum feeding practices can still be improved.

The live body weight (LBW) is an important parameter providing guidance for estimation of growth and feed conversion efficiency, body condition, presence of disease, and management of housing, nutrition, and animal health in different life stages of livestock. My master research was focused on exploring the feasibility of a semi-automatic analytic system that estimated the LBW of pigs by applying machine learning methods that use approximated morphometric measurements extracted from digital images acquired with a consumer-level camera in the presence of a reference object.

Commercial poultry diets are deficient in omega-3 fatty acids (n-3 FA) that are essential for embryonic brain development. Feeding n-3 FA to broiler and layer breeder chickens may directly benefit them and could increase the health, welfare, and productivity of their offspring. The aim of this thesis was to assess the effects of maternal feeding n-3 FA on the brain size and n-3 FA concentration, cognition, and fearfulness of layer and broiler offspring.

Livestock Research and Innovation invites faculty and students for a workshop on how to improve getting research into practice.  Speakers will emphasize how we are at a critical moment, how GRIP currently works and how to make it better. An industry panel will discuss their experience, sharing their first-hand knowledge on how they implement research. The afternoon session will feature a workshop to help build skills and explore possibilities. The Alda Communication Program will work to help everyone build a plan to take the next steps.

Title: The effects of natural monthly variations in environmental conditions on select serum and plasma electrolyte concentrations in healthy adult outdoor housed dogs and horses at rest.

  Good morning CGIL, This week we are happy to have Dr. Luciana Regitano, Research at Embrapa Southeast Livestock, presenting for us on Friday, April 14th, 2023. The seminar will begin at 1:30 PM EDT/EST on the virtual platform Microsoft Teams. The title of the presentation is: "Could the Bos indicus hologenome be considered for breeding purposes?".
