Partial replacement of soybean meal with cottonseed meal in diets of broiler chicken sustains performance by upregulating the expression of nutrient transporter genes in small inte... by S. Haldar, S.S. Arora, A.K. Dhara, A. Debnath

“…Inclusion of the HF-CSM upregulated the expression of nutrient co-transporter genes responsible for absorption of small peptides (PEPT-1), glucose and other hexose sugars (SGLT-1, GLUT-5), and amino acids (EAAT-3) in the small intestine at 24 d (P = 0.001, linear effect) and 42 d (P = 0.001, quadratic effect). Expression of PYY mRNA, associated with satiety regulation, increased with HF-CSM levels in diet at 24 d (P = 0.0001 linear effect) and 42 d (P = 0.001, linear effect), suggesting a potential anorexigenic effect. …”
