Project description:This study aimed to determine the metabolic response of growing Fleckvieh bulls fed diets low in crude protein (CP) supplemented with rumen-protected methionine (RPM). In total, 69 bulls were assigned to three dietary treatments (n=23/group): Positive control (CON; 13.7% CP; 2.11 g methionine/kg DM) and negative control deficient in crude protein (RED; 9.04% CP; 1.56 g methionine/kg DM) with supplemented RPM (RED+MET; 9.04% CP; 2.54 g methionine/kg DM). At slaughter, samples of liver, muscle and blood serum were taken and underwent subsequent metabolomics profiling using a UHPLC-QTOF-MS system. A total of 6,540 features could be detected. 70 metabolites in the liver, six metabolites in muscle and 60 metabolites in blood serum were affected (p < 0.05) due to die-tary treatments. In total, five metabolites could be reliably annotated and were thus subject to subsequent univariate analysis. Reduction in dietary CP had hardly any effect on metabolite abundance in target tissues of both RED and RED+MET bulls as compared CON bulls. Addition of RPM altered hepatic anti-oxidant status in RED+MET bulls as compared to both RED and CON bulls (cysteine glutathione disulfide) . Results exemplify nutrient partitioning in growing Fleckvieh bulls: bulls set maintenance as prevailing metabolic priority (homeostasis) and as a second priority, nutrient trafficking is directed towards special metabolic functions, such as an-ti-oxidant pathways.

Project description:The objective of this study was to examine changes in hepatic gene expression of growing bulls during a period of dietary energy restriction followed by a period of subsequent realimentation and compensatory growth. Purebred Holstein Friesian bulls (n=20) were assigned to one of two feeding treatments (i) restricted feed allowance for 125 days (n=10) followed by ad libitum access to feed for a further 55 days or (ii) a control group with ad libitum access to feed through out the 180 days trial (n=10). The first 125 days of the trial were denoted as Peirod 1, during which treatment groups were fed differentially. The subsequent 55 days, denoted as Period 2 during which all bulls were fed ad libitum. All bulls received the same diet of 70% concentrate 30% grass silage through out the experimental trial,with the amount of feed provided different dependnet on each treatment group. At the end of each period, 10 animals from each treatment group (10, restricted fed and 10 ad libitum fed) were slaughtered and hepatic tissue collected within thirty minutes of slaughter. RNA was extracted and hepatic gene expression was examined using RNAseq technology and bioinformatic analysis. During the differential feeding period, over-represented pathways including amino acid and lipid metabolism, protein synthesis and cell cycle/proliferation were identified, which indicate alterations in metabolic and growth rate in the liver during dietary restriction . During the realimentation period, pathways involved in cell cycle and cell growth as well as protein synthesis were over-represented, with the direction of fold changes opposite to that of these pathways in Period 1. This information can be exploited in genomic breeding programmes to assist selection of cattle with a greater ability to compensate following a period dietary restriction.

Project description:The objective of this study was to examine the effect of dietary restriction and subsequent re-alimentation induced compensatory growth on the global gene expression profile of ruminal epithelial papillae. Holstein Friesian bulls (n=38) were assigned to one of two groups: restricted feed allowance (RES; n=19) for 125 days (Period 1) followed by ad libitum access to feed for 55 days (Period 2) or (ii) ad libitum access to feed throughout (ADLIB; n=19). All bulls received the same diet of 70% concentrate 30% grass silage through out the experimental trial,with the amount of feed provided different dependent on each treatment group. At the end of Period 1, 9 animals from each treatment group were slaughtered, with 10 animals from each treatment slaughtered at the end of Period 2. Rumen epithelium was collected from all animals within thirty minutes of slaughter. RNA was extracted and rumen epithelium gene expression was examined using RNAseq technology on all samles collected (end of Period 1: 9 samples each from ADLIB and RES groups; end of Period 2: 10 samples each from ADLIB and RES groups). Genes identified as differentially expressed in response to both dietary restriction and subsequent compensatory growth included those involved in processes such as cellular interactions and transport, protein folding and gene expression, as well as immune response. This information can be exploited in genomic breeding programmes to assist selection of cattle with a greater ability to compensate following a period dietary restriction.

Project description:The objectives of our study were to identify microRNA (miRNA) present in bovine sperm and to evaluate the effects of fescue toxicosis on sperm miRNA expression. Angus bulls were assigned to treatments of either toxic or non-toxic fescue seed diets. Semen was collected and subjected to microRNA (miRNA) isolation after 126 days. Three bull's sperm miRNA samples from each treatment group were chosen and pooled for deep sequencing. Sequencing results were used to create a custom microarray for miRNA comparison between groups. LC Sciences was used as a service provider for the sequencing and custom microarray.

Project description:The objective of this study was to examine changes in muscle gene expression of growing bulls during a period of dietary energy restriction followed by a period of subsequent realimentation and compensatory growth. Purebred Holstein Friesian bulls (n=20) were assigned to one of two feeding treatments (i) restricted feed allowance for 125 days (n=10) followed by ad libitum access to feed for a further 55 days or (ii) a control group with ad libitum access to feed through out the 180 days trial (n=10). The first 125 days of the trial were denoted as Peirod 1, during which treatment groups were fed differentially. The subsequent 55 days, denoted as Period 2 during which all bulls were fed ad libitum. All bulls received the same diet of 70% concentrate 30% grass silage through out the experimental trial,with the amount of feed provided different dependnet on each treatment group. Muscle biopsies were collected at 2 time points (end of the differential feeding in Period 1 (d 120) and during the realimentation phase in Period 2 (d 15 of re-alimentation). RNA was extracted and muscle gene expression was examined using RNAseq technology and bioinformatic analysis. During the differential feeding period, over-represented pathways including fatty acid beta oxidaiton, oxidative phosphorylation and TCA cyclewere identified, which indicate utilisation of lipid sotes for energy utilisaiton and also alterations in energy produciton during dietary restriciton in muscle. During the realimentation period, pathways involved in energy produciton were over-represented, with the direction of fold changes opposite to that of these pathways in Period 1. additionally, a number of genes involved in cell division and cellular proliferation were up-regulated during compensatory growth in re-alimentation, thereby promoting accelerated cell growth and proliferation in muscle tissue of animals experiencing compensatory growth. This information can be exploited in genomic breeding programmes to assist selection of cattle with a greater ability to compensate following a period dietary restriction. 40 muscle RNA samples were analysed in total. 10 samples were from muscle biopsies collected at the end of a period of dietary restriction (d 120) and 10 samples were from muscle biopsis collected during the initial stages of compensatory growth (d 15 of re-alimentation). In addition, RNA was also anlaysed from 10 samples collected from animals fed a libitum at each of these two timepoints.
