Abstract
Achieving sustainable development is one of the greatest challenges for humanity. This includes producing food in ways that enhance ecosystem, animal, and human health. There is a need for deeper understanding of nutrient distribution across the edible parts of animals, to better measure this enhancement. This study examined nutrient distribution across the carcase and co-products (edible offal and slaughter fat) derived from a typical Australian lamb, using modelling with secondary data. Due to insufficient data, some offal types were not included. Co-products accounted for 24% of total edible product by weight, 18% of protein and 37% of fat. The co-products contained 42% of iron content and the liver had more vitamin A, B12 and folate than all other products combined. This study highlighted the nutritional value of edible offal, especially liver, in the context of the whole animal and, the importance of including co-products in assessments of animal production systems.

Title
Data set for "Distribution of nutrients across the edible components of a modelled typical Australian lamb: a case study"
Description
This dataset is the result of modelling in Excel, using secondary data sources that are available to the public. The data was created in Excel® during October 2020- January 2021 and was revised and updated in November 2022.
The model included the following edible components: carcase primal cuts, liver, kidney, tongue, heart, brain, spleen, lungs, tripe, thymus, pancreas and slaughter fat. The carcase specifications were based on those desirable for the Australian domestic market. All edible components were considered in the raw, untrimmed state.
The overall uncertainty of the outputs of this model was assessed as medium-to-high, so caution should be used when interpreting the results.
The dataset presents the nutrient content of each food product as both absolute values and as a proportion of total available nutrient in the model lamb. This dataset is important for assessing the sustainability of the Australian sheep meat value chain.
