WIC Infant and Toddler Feeding Practices Study-2 (WIC ITFPS-2): Prenatal, Infant Year, Second Year, Third Year, and Fourth Year Datasets

    The WIC Infant and Toddler Feeding Practices Study–2 (WIC ITFPS-2) addresses a series of research questions regarding feeding practices, the effect of WIC services on those practices, and the health and nutrition outcomes of children on WIC. These datasets include data from caregivers and their children during the prenatal period and during the children’s first four years of life (child ages 1 to 48 months).

    27 years of livestock production data under different stocking rate levels at the Central Grasslands Research Extension Center near Streeter, North Dakota

      The effects of stocking rate on livestock performance and profitability were monitored on 12 pastures at the Central Grasslands Research Extension Center (CGREC) near Streeter, ND from 1989 through 2015. These data were produced from an investigation of how the impacts of grazing intensity on native range, in addition an economic component, was included to determine grazing intensity effect on animal production.

      Data from: Skeletal Muscle Sexual Dimorphism in Mice

        File contains transcriptomics results for gastrocnemius (GA) and soleus (SOL) muscles from adult mice, previously fed a 45% (by energy) high fat diet for ~13 wk. The Supplemental Material also contains gene pathway analysis results (e.g., GO, HMDB), transcripts differentially expressed but with shared or disparate patterns in GA vs. SOL (Venn diagrams), and correlations between summed muscle weights vs. body weight or lean body mass.

        Data from: Starch and dextrose at 2 levels of rumen-degradable protein in iso-nitrogenous diets: Effects on lactation performance, ruminal measurements, methane emission, digestibility, and nitrogen balance of dairy cows.

          This feeding trial was designed to investigate two separate questions. The first question is, “What are the effects of substituting two non-fiber carbohydrate (NFC) sources at two rumen-degradable protein (RDP) levels in the diet on apparent total-tract nutrient digestibility, manure production and nitrogen (N) excretion in dairy cows?”. This is relevant because most of the N ingested by dairy cows is excreted, resulting in negative effects on environmental quality. The second question is, “Is phenotypic residual feed intake (pRFI) correlated with feed efficiency, N use efficiency, and metabolic energy losses (via urinary N and enteric CH4) in dairy cows?”. The pRFI is the difference between what an animal is expected to eat, given its level of productivity, and what it actually eats. The goal was to determine whether production of CH4, urinary N or fecal N is a driver of pRFI.
