- The objectives of the present study were to determine the effects of jugular vein infusions of glucagon like peptide-1 (GLP-1) and dietary fat inclusion on dry matter intake, nutrient digestibility and hypothalamic mRNA concentration of neuropeptide Y, agouti related peptide, and proopiomelanocortin in growing sheep. Thirty-six wethers were used (40.7±3.3 kg BW). Treatments were a control diet (n=11), dietary addition (6% of dry matter) of Ca salts of palm oil fatty acids (n=12), or 6-d jugular vein infusions of 0.155 µg kg-1 body weight/day of GLP-1 (n=11). Hormone concentrations were measured in jugular vein plasma from samples taken on days 1, 4 and 6. On day 7, the wethers were slaughtered for hypothalamus collection to measure mRNA concentration. The dietary addition of 6% of Ca salts of palm oil increased plasma GLP-1 concentration (P<0.01) and decreased dry matter intake on day 1, but not on day 6 (time×treatment interaction, P<0.05). The infusion of GLP-1 did not change dry matter intake (P>0.20), but increased neutral detergent fibre digestibility (P<0.01). In conclusion, glucagon like peptide-1 infusion or feeding fat did not decrease dry matter intake or affect hypothalamic neuropeptide mRNA concentrations of sheep.
Les objectifs de cette étude étaient d'évaluer les effets d'infusions de GLP-1 («glucagon-like peptide-1») dans la veine jugulaire et de l'inclusion alimentaire de matières grasses sur l'ingestion de matières sèches, la digestibilité des éléments nutritifs et la concentration en ARNm hypothalamique du neuropeptide Y, de la protéine reliée à l'Agoutie et de la pro-opiomélanocortine chez les moutons en croissance. Trente-six béliers castrés ont été utilisés (40,7±3,3kg de poids corporel). Les traitements étaient: la diète témoin (n=11), l'inclusion alimentaire (6% de la matière sèche) de sels de calcium d'acides gras d'huile de palme (n=12), ou 6 jours d'infusions dans la veine jugulaire de 0,155 µg kg-1 de poids corporel/jour de GLP-1 (n=11). Les concentrations d'hormones ont été mesurées dans le plasma de la veine jugulaire à partir d′échantillons prélevés les jours1, 4 et 6. Le jour7, les béliers ont été abattus pour la collecte de l'hypothalamus pour la mesure des concentrations d'ARNm. L'ajout de 6% de sels de calcium d'acides gras d'huile de palme a augmenté la concentration plasmatique de GLP-1 (P<0,01) et diminué l'ingestion des matières sèches au jour1, mais pas au jour6 (interaction temps×traitement, P<0,05). L'infusion de GLP-1 n'a pas eu d'effet sur l'ingestion des matières sèches (P>0,20), mais a augmenté la digestibilité des fibres au détergent neutre (P<0,01). En conclusion, l'infusion de GLP-1 et l'apport de gras n'ont pas eu d'effet sur l'ingestion des matières sèches ni des concentrations d'ARNm des neuropeptides hypothalamiques chez les moutons.
