Effects of maternal protein supplementation and inclusion of rumen‐protected fat in the finishing diet on nutrient digestibility and expression of intestinal genes in Nellore steers     

Wendell F. G. da Cruz  Jon P. Schoonmaker  Flavio D. de Resende  Gustavo R. Siqueira  Liziana M. Rodrigues  Germn D. R. Zamudio  Marcio M. Ladeira 《Animal Science Journal》2019,90(9):1200-1211

The study aimed to evaluate nutrient digestibility and intestine gene expression in the progeny from cows supplemented during gestation and fed diets with or without rumen‐protected fat (RPF) in the feedlot. Forty‐eight Nellore steers, averaging 340 kg, were housed in individual pens and allotted in a completely randomized design using a 2 × 2 factorial arrangement (dams nutrition × RPF). Cows' supplementation started after 124 ± 21 days of gestation. The feedlot lasted 135 days and diets had the inclusion of zero or 6% of RPF. Digestibility was evaluated by total feces collection. Steers were slaughtered using the concussion technique and samples of pancreas and small intestine were collected immediately after the slaughter to analyze α‐amylase activity, and the expression of SLC5A1, CD36, and CCK and villi morphometry. Feeding RPF increased nutrients digestibility (p < 0.01). There was no effect of maternal nutrition on digestibility and α‐amylase activity in steers (p > 0.05). Duodenal expression of SLC5A1, CD36, and CCK increased in the progeny from restricted cows. In conclusion, protein restriction during mid to late gestation of dams has long‐term effects on small‐intestine length and on expression of membrane transporters genes in the duodenum of the progeny. However, maternal nutrition does not affect digestibility in the feedlot.  相似文献

Effect of l‐glutamic acid supplementation on performance and nitrogen balance of broilers fed low protein diets          下载免费PDF全文

The aim of this study was to evaluate the effect of protein reduction and supplementation of l ‐glutamic acid in male broiler diets. A total of 648 chicks of the Cobb 500 strain were distributed in a completely randomized design with six treatments and six replications with eighteen birds per experimental unit. The study comprised pre‐starter (1–7 days), starter (8–21 days), growth (22–35 days) and final (36–45 days) phases. The first treatment consisted of a control diet formulated according to the requirements of essential amino acids for each rearing phase. The second and third treatments had crude protein (CP) reduced by 1.8 and 3.6 percentage points (pp) in relation to the control diet respectively. In the fourth treatment, l ‐glutamic acid was added to provide the same glutamate level as the control diet, and in the last two treatments, the broilers were supplemented with 1 and 2 pp of glutamate above that of the control diet respectively. The reduction in CP decreased the performance of broilers and the supplementation of l ‐glutamic acid did not influence performance when supplied in the diets with excess of glutamate. The lowest excreted nitrogen values were observed in the control diet, and treatments 2 and 3, respectively, in comparison with treatments with the use of l ‐glutamic acid (5 and 6). Retention efficiency of nitrogen was better in the control diet and in the treatment with a reduction of 1.8 pp of CP. It was verified that the serum uric acid level decreased with the CP reduction. A reduction in CP levels of up to 21.3%, 18.8%, 18.32% and 17.57% is recommended in phases from 1 to 7, 8 to 21, 22 to 35 and at 36 to 42 days, respectively, with a level of glutamate at 5.32%, 4.73%, 4.57%, 4.38%, also in these phases.  相似文献   

Wnt5a expression in canine osteosarcoma          下载免费PDF全文

Osteosarcoma is the most common primary malignancy of bone in dogs and is associated with poor long‐term outcomes due to its highly metastatic nature. A better understanding of the signalling pathways and proteins involved with osteosarcoma pathogenesis may aid in improved outcomes through the use of targeted therapies. The Wnt5a protein, a ligand for the non‐canonical Wnt signalling pathway, is implicated in mediating the aggressiveness of cancer cell lines, including those of human osteosarcoma origin. Given the close relationship between human and canine osteosarcoma, the primary goal of this study was to characterize Wnt5a expression in canine osteosarcoma. Second, if Wnt5a expression was present in canine osteosarcoma, the study aimed to determine any potential association with clinical outcome and clinical variables in similarly treated osteosarcoma‐bearing dogs. Wnt5a expression was present in 26 of the 48 (54%) cases of canine osteosarcoma. Wnt5a expression was not associated with progression‐free survival (P = 0.4) or overall survival (P = 0.1).  相似文献
