Project description:This study aimed to evaluate the effect of including soybean molasses (SM) on performance, blood parameters, carcass traits, meat quality, fatty acid and muscle (longissimus thoracis) transcriptomic profiles of castrated lambs. Twenty Dorper × Santa Inês lambs (20.06 ± 0.76 kg BW) were assigned to a randomized block design, stratified by BW, with the following treatments: CON - 0 g/kg of SM and SM20 - 200 g/kg of SM on DM basis, allocated in individual pens. The diet consisted of 840 g/kg concentrate and 160 g/kg corn silage for 76 days, with the first 12 days as an adaptation period and the remaining 64 days on the finishing diet. The SM20 diet increased blood urea concentration (P = 0.03) while reduced glucose concentration (P = 0.04). Lambs fed SM showed higher subcutaneous fat deposition (P = 0.04) and higher subcutaneous adipocyte diameter (P < 0.01), in addition to reduced meat lipid oxidation (P < 0.01). Soybean molasses reduced the quantity of branched-chain fatty acids in longissimus thoracis (P = 0.05) and increased the quantity of saturated fatty acids (P = 0.01). In the transcriptomic analysis, 294 genes were identified as differentially expressed, which belong to pathways such as oxidative phosphorylation, citric acid cycle, and monosaccharide metabolic process. In conclusion, diet with SM increased carcass fat deposition, reduced lipid oxidation, and changed the energy metabolism, supporting its use in ruminant nutrition.

Project description:Differences in adipose tissue deposition and properties between pig male sex categories, i.e., entire male, immunocastrated and surgically castrated pigs are relatively well characterized, whereas the underlying genetic mechanisms are still not fully understood. To gain the knowledge about the genetic regulation of the differences in adipose tissue deposition, RNA-sequencing approach was used. A total of 83 differentially expressed genes were identified between entire male and immunocastrated pigs, 15 between immunocastrated and surgically castrated pigs and 48 between entire male and surgically castrated pigs by RNA-sequencing of the subcutaneous adipose tissue. Comparing entire male with immunocastrated or surgically castrated pigs, upregulated genes related to extracellular matrix dynamics, and downregulated genes involved in the control of lipid and carbohydrate metabolism were determinated. Moreover, differential gene expression in general indicated a high similarity between immunocastrated and surgically castrated pigs in contrast to entire males, except for several heat shock protein genes which were upregulated in entire male and immunocastrated pigs compared with surgically castrated pigs.

Project description:Feeding animals with either concentrates supplemented with vitamin E or alfalfa grazing has been proven to reduce the oxidative process that occurs in meat products. Indoor-kept lambs were fed a standard concentrate (n=7, C) or concentrate supplemented with vitamin E (n=7, VE) for 30 days before slaughtering all animals at 22–24 kg of live weight. Simultaneously, 7 unweaned lambs grazed in alfalfa paddocks (ALF) with their dams. Global transcriptomic data of longissimus thoracis (LT) muscle and subcutaneous fat (SF) with the Affymetrix® Ovine Gene 1.1 microarray was used. In LT muscle when ALF group was compared with C group, were identified 41 genes differentially expressed. Among these genes 32 were down- regulated and 9 were up- regulated. Meanwhile when VE treatment was compared with C group were identified a total of 29 genes, 26 were down- regulated and 3 genes were up- regulated. In SF when ALF treatment was compared with C, were identified only 4 genes differentially expressed, all of them up-regulated in ALF group. Meanwhile when VE treatment was compared with C group, were identified a total of 330 genes. Among them, 295 genes were up- regulated and 35 were down- regulated. In LT muscle the clusters corresponding to gene expression profiles from treatments ALF, C and VE were clearly separated from each other. In SF, ALF group, overlap with VE and C treatments, however, VE and C clearly were separate in different clusters. These differentially expressed genes were selected for a functional analysis by using DAVID. In LT muscle some of the identified significant biological processes were catabolic and lipid process (down-regulated, except CPT1B) (CPT1B, PLA2G16, SPSB1, LRTOMT, PLCD4, FBXO9, CNBP and CYP27A1) and muscle organ differentiation (down-regulated) (CPT1B, MYOD1, MYLK2 and MSTN) in ALF; whereas intracellular signaling cascade (IGF1R, DEF8, AKAP7 and CISH) was down-regulated. In SF, vitamin E supplementation had an important effect; most of the genes were up-regulated. DAVID analysis showed that biosynthesis lipid pathway was the most represented with 20 genes, such as EBP, MVD, CYP51A1, DHCR7, HMGCS1, LSS and FDFT1 implicated in cholesterol synthesis. Further exploration of the links between these genes and vitamin E will lead to a better understanding of how vitamin E affects the oxidative process that occurs in meat products.

Project description:Samples of perirenal fat tissue from 8 Assaf breed suckling lambs. These animals were selected from a larger group of 17 Assaf suckling lambs for which carcass traits were measured. The 8 selected lambs were those showing the highest and the lowest values, from the larger group, for the percentage of perirenal and cavitary fat relative to the half carcass weight. Hence, considering the values for this trait, we defined the High-PF group (n = 4; average: 3.23 ± 0,.47) and the Low-PF group (n = 4; 1.65 ± 0,.16), respectively.

Project description:Our group has developed an extra-uterine environment for newborn development (EXTEND) using an ovine model, that aims to mimic the womb to improve short and long-term health outcomes associated with prematurity. This study’s objective was to determine the histologic and transcriptomic consequences of EXTEND on the brain. Histology and RNA-sequencing was conducted on brain tissue from three cohorts of lambs: control pre-term (106-107 days), control late pre-term (127 days), and experimental lambs who were born pre-term and supported on EXTEND until late pre-term age (125-128 days). Bioinformatic analysis determined differential gene expression among the three cohorts and across four different brain tissue sections: basal ganglia, cerebellum, hippocampus, and motor cortex. There were no clinically relevant histological differences between the control late pre-term and EXTEND ovine brain tissues. RNA-sequencing demonstrated that there was greater differential gene expression between the control pre-term lambs and EXTEND lambs than between the control late pre-term lambs and EXTEND lambs. Our study demonstrates that the use of EXTEND to support pre-term lambs until they reach late pre-term gestational age results in brain tissue gene expression that more closely resembles that of the lambs who reached late pre-term gestation within their maternal sheep’s womb than that of the lambs who were born prematurely.

Project description:The callipyge mutation causes postnatal muscle hypertrophy in heterozygous lambs that inherit a paternal callipyge allele (+/CLPG). Our hypothesis was that the up-regulation of one or both of the affected paternally expressed genes (DLK1 or PEG11) initiates changes in biochemical and physiological pathways in skeletal muscle to induce hypertrophy. The goal of this study was to identify changes in gene expression during the onset of muscle hypertrophy in order to identify the pathways that are involved in the expression of the callipyge phenotype. Gene expression was analyzed in longissimus dorsi total RNA from lambs at 10, 20, and 30 days of age using the Affymetrix Bovine Expression Array. Experiment Overall Design: Longissimus dorsi were collected from 10, 20, and 30 day old callipyge and normal lambs with 2 biological replicates for each group. Total RNA was isolated and hybridized to Affymetrix Bovine Expression arrays. Data were analyzed in SAS and all genotype effects were followed up by qPCR in 42 lambs ranging from 10 to 200 days of age.
