background and objective: one way to promote education quality is to evaluate faculty activities by students, departmental heads, and the dean. the degree of correspondence between students' and departmental heads' evaluation shows how honest they are in their assessment. the current paper intends to find the truth.     materials and methods : questionnaires were used to conduct the s...

This study investigated the correlation between the body surface temperature (BST) and core body temperature of ewes and changes in BST during the prepartum stage in pregnant ewes. Four non-pregnant adult ewes were used in the first experiment. The BST of the upper neck, vaginal temperature (VT), and ambient temperature (AT) were measured every 10 min for seven days and analyzed for correlation...

Digital infrared thermal imaging (DITI) using a thermal camera has potential to be a useful tool for the production animal industry. Thermography has been used in both humans and a wide range of animal species to measure body temperature as a method to detect injury or inflammation. The objective of these experiments was to compare the temperature of the eye (EYE) or muzzle (MUZ) measured using...

The present study evaluated the effects of diets enriched in saturated and polyunsaturated fatty acids (n-3and n-6) on reproductive indices, metabolic hormones and metabolites prior to ram introduction in oestrussynchronized ewes. Zel ewes (n=188) were assigned to 4 groups. Ewes in the control group (CON) did notreceive fat. Ewes in the 3 other groups received 3% oil/DM/day of palmolein oil (PL...

Large offspring syndrome (LOS) may be initiated in ovine embryos after exposure to in vitro conditions. The objective of this study was to compare various parameters of the gravid uterus on day 140 after fertilization: (i) in ewes (n=4) bred naturally, and in ewes (n=18) after transfer of embryos produced in vitro, and (ii) in single, twin and triplet pregnancies after transfer of in vitro prod...

The aim of this study was to determine the effect olive oil addition on production, chemical composition, and fatty acid profile sheep’s milk. Twenty-four lactating ewes with a live weight 34.6 ± 4.61 kg were used. animals randomly distributed into four treatments (n = 6) dietary 0%, 2%, 4%, 6% (dry matter basis) for 45 days. Milk samples taken every 7 days (FA) analyses. A decrease (p < 0.0...

Several studies in dairy cows have shown a relationship between milk fat depression (MFD) and alterations caused in lipogenic gene expression by dietary nutrients. However, information on small ruminants is not only scarce but also inconsistent. Therefore, this experiment was conducted in dairy ewes to study the effect of a diet known to induce MFD on milk fatty acid (FA) composition and mRNA a...
