Spiculopteragia asymmetrica is a gastrointestinal nematode frequently found in the abomasum of cervids. During December and February 2010, two red deer were died in Semeskandeh sanctuary in Mazandaran province. Moreover, five live deer from mentioned area were treated by Ivermectin and collected feces of these animals were used for assessment helminthes infection by parasitological methods. Sev...

The study was aimed at determining the age-depended changes in insulin-like growth factors 1 and 2 (IGF-1 and IGF-2) mRNA levels in relation to the gastrointestinal tract (GIT) development in newborn calves. Twenty four male calves (5-day-old) were randomly allocated to 4 groups which were slaughtered at day 5, 12, 19 and 26 of their life, respectively. Tissue samples from the rumen, abomasum, ...

Received: 07/12/2013 Revised: 20/12/12013 Accepted: 22/12/2013 Abstract The present study was conducted to observe the gross and microscopic changes in gastro-intestinal tract during helminth infestation in camels. Grossly, abomasum showed varying degrees of ulceration, congestion of mucosa, thickened walls and oedematous folds associated with haemorrhagic foci due to presence of Haemonchus spp...

Eight five-month-old male lambs received a diet with marginal levels of sodium (0.5 g Na/kg DM); four lambs were given a single dose of infective Haemonchus contortus larvae (4,600 L3/ head) and four were kept uninfected. The lambs were slaughtered 30 days after the infection. Sodium concentration was determined in the abomasal fluid at the slaughter. The balance between intake and faecal excre...

Intestinal radiocalcium absorption was measured in goats by a double-isotope technique involving injection of 45CaCl2 intravenously and 47CaCl2 into the abomasum. Cumulative absorption of radiocalcium was calculated by deconvolution analysis form curves of plasma radioactivity. Repeated measurements at 2 d intervals gave highly reproducible results (r 0.94, P less than 0.001). No systematic dif...

Enteric neurons are able to alter their neurotransmitter content during adaptation to new artificial conditions. The aim of the present study was to investigate changes in vasoactive intestinal peptide (VIP), substance P (SP) and galanin expression during culture of myenteric neurons from the ovine abomasum. In order to accurately reflect the in vivo situation cryostat sections from the ovine a...

Homozygous grey and white Karakul lambs die after they have reached weaning age. This is due to a lethal gene causing digestive disturbances. Previous studies revealed that grey and white lambs have large, milk-filled rumens; the phenomenon was attributed to a significant decrease in the number of myenteric ganglia and neurons in the rumen wall. This study was undertaken to determine whether an...

The effect of starch infusion on production, metabolic parameters and relative mRNA abundance was investigated in low yield lactating cows from 86 days in milk. Six Holstein cows fitted with permanent ruminal cannulas were arranged into one of two complete 3×3 Latin squares and infused with a starch solution containing 800 grams starch for 16 days. The three treatments were: i) ruminal and abom...
