Formulating broiler starter diets incorporates specialty highly digestible protein feedstuffs (SPF) in partial replacement of soybean meal (SBM) and antibiotic growth promoters (AGP) in alignment with immature digestive capacity. There is limited comparative data on the effectiveness of SPF on lifetime growth performance, gastrointestinal function and metabolism. Experiments were conducted to assess impacts of 4 SPF (enzyme treated soybean meal, soy protein concentrate, pork meal, and black soldier fly larvae meal) in starter on these parameters.

Coccidiosis is an avian parasitic disease, caused by the protozoan genus Eimeria, and a significant contributor to economic losses in poultry production due to its detrimental effects on nutrient absorption and growth performance. A meta-analysis was first completed to summarize and quantify the effects of an Eimeria infection on the AID of AA in broiler chickens. Experiment 1 was conducted to determine the SID of AA of main feed ingredients either fed as a single ingredient-based diet or a mixed ingredient-based diet to broiler chickens infected with Eimeria.

Feed efficiency has been a major topic of interest in the dairy industry over the past decade. In recent years, feed efficiency in lactating animals has been incorporated into selection indices, but little is known about feed efficiency in calves. The objective of this thesis was to investigate feed efficiency in preweaning Canadian Holstein calves and estimate its genetic parameters. Preweaning is a significant period in a calf’s life, as man-agement can impact lifetime productivity, and rearing costs are a major expense for producers.

Genetic selection of dairy cattle for improved stressed resiliency is one strategy for mitigating the harmful effects of stressors that are expected to intensify as a result of climate change. With global temperatures increasing 0.15-0.20 °C since 1975, there has been a reduction in the quantity and quality of feedstuffs and drinking water, promoting the survival and distribution of pathogens and their vectors.

Ovarian follicular development is an important process that ensures female reproductive health and ovarian function. Many nutrients and microRNAs are known to play a role in regulating follicular cell proliferation, differentiation, extracellular ma-trix formation and ovulation during follicular development. Choline is an essential nutrient that has been shown to play criti-cal roles in the development and function of organs such as the brain and liver. It is reported that aberrant choline metabolism occurs in many ovarian-related diseases.

Good afternoon CGIL, This week we are happy to have Dr. Sarah Miller, Senior Genomics Research Scientist at Semex, presenting for us on Friday, April 28th, 2023. The seminar will begin at 1:30 PM EDT/EST on the virtual platform Microsoft Teams. The title of the presentation is: "Scrotal Circumference Genomic Evaluation and its Association with Semen Production in Semex’s Dairy Bull Population".
