“…The ducts of both parotid glands were ligated also. The submandibular saliva secreted after administration of different sialogogic agents was collected from the floor of the mouth with capillarymicropippete (Iwabuchi and Masuhara, 1995) during 5 min time; 10 additional minutes were allowed until the next dose was injected.…”

“…There is also a possible interaction of VIP and thermal environments. The potential of VIP to stimulate submandibular salivary gland secretion (Iwabuchi and Masuhara 1995) and decrease water absorption (Hyun et al 1995) may have caused thirst signals to induce more water intake to meet requirements under environmental conditions of exp. 2, but these would depend upon VIP escaping clearance processes.…”

. 2002. Effect of vasoactive intestinal polypeptide and environmental temperatures on feed intake, digesta flow and nutrient digestion in sheep. Can. J. Anim. Sci. 82: [165][166][167][168][169][170][171][172]. Three experiments were conducted to test the hypothesis that vasoactive intestinal polypeptide (VIP) infused into the gastric artery and exposure to a low temperature will increase feed intake, duodenal flow and amino acid supply to the small intestine of sheep, both effects as a result of increased ruminal outflow. A total of eight sheep (55 ± 2.7 kg) with rumen and duodenal cannulae and eight sheep without digestive cannulae were provided with continuous access to a diet of alfalfa pellets. Water and salt licks were accessible 24 h d -1 . Two infusion treatments, VIP (1 nmol min -1 ) solution or a saline control (0.9% NaCl solution) were given through a left gastricartery catheter for 10 min each hour for the first 3 h after feeding each day for 3 to 4 consecutive days in a crossover arrangement during experimental periods. Sheep were exposed to 1 ± 2°C in exp. 1, to a thermoneutral (21 ± 2°C) environment in exp. 3 and to both thermoneutral (21 ± 1.5°C) and cold environments (1 ± 2°C) in exp. 2. These studies demonstrated that a VIP infusion of short duration did not increase dry matter intake (DMI) (P > 0.05) and did not influence duodenal passage of DM, OM, CP, amino acids (AA) or bacterial protein (P > 0.05). The exposure of animals to a cold environment stimulated (P < 0.05) intake of DM, OM and AA and duodenal passage of DM, OM, AA and microbial protein. There was an interaction (P < 0.05) between VIP and environmental temperature such that VIP improved duodenal AA passage in the thermoneutral, but not in the cold, environment. The data suggest that short-term VIP treatment does not induce a change in feed intake when sheep have access to feed for 24 h d -1 . Cold environmental temperature stimulates significant increases in feed intake and passage of protein and AA into the small intestine of sheep fed ad libitum, such that there was enrichment of intestinal supply of AA relative to digestible organic matter. Les animaux avaient aussi accès à de l'eau et à des blocs à lécher 24 heures par jour. Du PIV (1 nmol par minute) et de la saline (solution de NaCl à 0,9 %), comme solution témoin, ont été administrés aux animaux au moyen d'un cathéter inséré dans l'artère gastrique 10 minutes par heure pendant les 3 premières heures suivant l'alimentation, 3 ou 4 journées d'affilée, dans le cadre d'un plan croisé. Les animaux ont été exposés à une température de 1 ± 2°C lors de la première expérience, à une température neutre (21 ± 2°C) lors de la troisième et aux deux températures lors de la deuxième (température neutre de 21 ± 1,5°C et température froide de 1 ± 2°C). Les résultats révèlent qu'une brève infusion de PIV n'augmente pas la prise de matière sèche (MS) (P > 0,05) et n'exerce aucune influence sur le transit de la MS, de la matière organique, des protéines brutes, des acides aminés et des protéines...
