In the present study, we investigated the effects of chromium-picolinate (CrPic) and chromium-histidinate (CrHis) on nutrient digestibility and nutrient transporters in laying hens exposed to heat stress (HS). Hens (n = 1800; 16 wk old) were kept in cages in temperature-controlled rooms at either 22 ± 2 °C for 24 h/day (thermoneutral (TN)) or 34 ± 2 °C for 8 h/day, from 08:00 to 17:00, followed by 22 °C for 16 h (HS) for 12 wk. Hens reared under both environmental conditions were fed one of three diets: a basal diet and the basal diet supplemented with either 1.600 mg of CrPic (12.43% Cr) or 0.788 mg of CrHis (25.22% Cr) per kg of diet, delivering 200 μg elemental Cr per kg of diet. HS impaired the nutrient digestibility and nutrient transports in laying hens (P < 0.001). However, both Cr sources increased digestibility of dry matter (DM; P < 0.001), organic matter (OM; P < 0.05), crude protein (CP; P < 0.001), and crude fat (CF; P < 0.001). Both Cr sources partially alleviated detrimental effects of HS on fatty acid-binding and transport protein1 (FABP1, FATP1), glucose (SGLT1, GLUT1, GLUT10), protein (PepT1, PepT2), and amino acid transporters (ASCT1, bo,+AT1, CAT1, EAAT1, LAT1) of the ileum (P < 0.0001). The efficacy of Cr as CrHis was more notable than Cr as CrPic, which could be attributed to higher bioavailability. Finally, the detrimental effects of HS on nutrient digestibility and nutrient transporters were alleviated by CrPic and CrHis. These findings may justify the use of CrPic and CrHis in poultry. In the experiment, the researchers used Picolinic acid(cas: 98-98-6Application of 98-98-6)
Picolinic acid(cas: 98-98-6) is used as a chelate for alkaline earth metals. Used to prepare picolinato ligated transition metal complexes. In synthetic organic chemistry, has been used as a substrate in the Mitsunobu reaction and in the Hammick reaction.Application of 98-98-6
