Metabolomics Changes in Meat and Subcutaneous Fat of Male Cattle Submitted to Fetal Programming.

This study investigated changes in meat and subcutaneous fat metabolomes and possible metabolic pathways related to prenatal nutrition in beef cattle. For this purpose, 18 Nellore bulls were used for meat sampling and 15 for fat sampling. The nutritional treatments during the gestation were: NP-not programmed or control, without protein-energy supplementation; PP-partially programmed, with protein-energy supplementation (0.

Evaluation of Maternal Nutrition Effects in the Lifelong Performance of Male Beef Cattle Offspring.

This study aimed to evaluate the effects of different prenatal nutrition treatments on pregnant cows and their progeny. One hundred and twenty-six pregnant Nellore cows (455.3 ± 8.

Effects of different maternal nutrition approaches on weight gain and on adipose and muscle tissue development of young bulls in the rearing phase.

This study evaluated the effects of prenatal nutrition on body weight (BW), average daily gain (ADG), rump fat thickness (RFT), backfat thickness (BFT), ribeye area (REA), muscle cell area (MCA), and the number of cells in REA (NCREA) of young Nellore bulls during the rearing period. After pregnancy confirmation (30 days of pregnancy), 126 Nellore cows were separated into three prenatal nutritional treatments (NP (control; 0.03% of BW), only mineral supplementation; PP (0.
