Optimising compensatory growth in pastoral beef production systems: insights into feed efficiency, body composition, carcass characteristics and meat quality attributes.

Exploitation of compensatory growth (CG) is a widely practised management strategy in beef production, especially under pastoral conditions due to its potential to reduce feed costs. The aim of this experiment was to evaluate the effect of nutritional restriction during backgrounding in Angus steers slaughtered at either similar age and/or similar BW on feed efficiency, body composition, carcass characteristics and meat quality attributes under either a forage or feedlot-based finishing diet. Eighty steers (BW: 444 ± 39 kg, age: 18 ± 1 months) were blocked and randomly assigned within block to either an optimal (0.

IL-7 promotes integrated glucose and amino acid sensing during homeostatic CD4 T cell proliferation.

Interleukin (IL)-7 promotes T cell expansion during lymphopenia. We studied the metabolic basis in CD4 T cells, observing increased glucose usage for nucleotide synthesis and oxidation in the tricarboxylic acid (TCA) cycle. Unlike other TCA metabolites, glucose-derived citrate does not accumulate upon IL-7 exposure, indicating diversion into other processes.

Relationships Between Gonadotropins, Sex Hormones, and Vascular Health in Adolescents with Normal Weight or Obesity.

Relationships between gonadotropins, sex hormones, and vascular structure and function in adolescents of varying weight statuses have not been fully investigated. In the present study, we examined associations among these in female and male adolescents with normal weight or obesity. We performed a cross-sectional analysis of adolescents ( = 58; 12-<18 years) grouped according to BMI percentile (BMI%) into normal weight (5th-<85th BMI%; = 25) and obesity (≥95th BMI%; = 33) categories.
