The objective of present study was identification of genetic similarity between wild Iran and captive Azerbaijan Pheasant using PCR-RAPD markers. For this purpose, in overall, 28 birds were taken for DNA extraction and subsequently 15 arbitrary primers were applied for PCR-RAPD technique. After electrophoresis, five primers exhibited sufficient variability which yielded overall 65 distinct bands, 59 polymorphic bands, for detalis, range of number of bands per primer was 10 to 14, and produced size varied between 200 to 1500bp. Highest and lowest polymorphic primers were OPC5, OPC16 (100) and OPC15 (81), respectively. Result of genetic variation between two groups was accounted as nonsignificant (8.12) of the overall variation. According to our expectation the wild Iranian birds showed higher genetic diversity value than the Azerbaijan captive birds. As general conclusion, two pheasant populations have almost same genetic origin and probably are subpopulations of one population. The data reported herein could open the opportunity to search for suitable conservation strategy to improve richness of Iran biodiversity and present study here was the first report that might have significant impact on the breeding and conservation program of Iranian pheasant gene pool. Analyses using more regions, more birds, and more DNA markers will be useful to confirm or to reject these findings. Copyright © 2012 Ghorban Elyasi Zarringhabaie et al.

The work aimed to study the digestive capacity and nitrogen balance of Cinta Senese pig fed diets with different crude protein (CP) content. Twelve castrated male pigs (6 Cinta Senese and 6 Large White), of the same body weight (on average 62.7. kg), were submitted to 8 subsequent trials of total tract digestibility and nitrogen balance. The pigs were kept in metabolism cages allowing collection of faeces samples and total urine. The diets, of exclusive vegetal origin, were formulated to contain four protein levels 70, 100, 130 and 160. g/kg as fed (named CP7, CP10, CP13 and CP16, respectively) assured mainly by soybean meal. Total tract nutrient apparent digestibility did not differ (P>0.05) between breeds. Apparent digestibility of CP increased (P<0.01) with increasing dietary CP (from 0.756 to 0.874 for Cinta Senese and from 0.742 to 0.868 for Large White), as consequence of faecal endogenous nitrogen which underestimates the digestibility of protein in inverse proportion with its amount in the diet. Nitrogen balance showed that breed differences (P<0.01) emerged for the urinary N and the total excreted N, with higher emission in Cinta Senese than in Large White breed. The difference was not significant at CP7 diet (excreted N: 19.4 vs. 17.1. g/d for Cinta Senese and Large White) but became progressively more important (P<0.01) in the diets with higher CP content (excreted N at CP16 diet: 39 vs. 35.4. g/d for Cinta Senese and Large White). Consequently, Large White retained more nitrogen than Cinta Senese (about +2.6; +3.0; +3.4; +3.8. g/d with CP7; CP10; CP13; CP16 diet, respectively; P<0.01). So, the efficiency of N utilization (retained N/absorbed N), favoured the Large White in all the tested diets (P<0.01). These results suggest to limit the CP content in diets for Cinta Senese breed, to reduce nitrogen pollution in the environment. © 2011 Elsevier B.V.

The opinions of students at the Faculty of Agriculture (Seville University, Spain) concerning the educational usefulness and the affectation of the rabbits welfare of a university farm for teaching Rabbit Farming were analyzed. Both prior to beginning the course as well as upon completion, the majority of students supported the use of the farm for conducting the practicals (97.9% before the course; 100.0% after) they prefenedto learn on the university farm rather than visiting commercial farms (90.7% before; 95.3% after) and they believed the welfare of the rabbits was not harmed (63.8% before; 54.7% after), or if it was harmed that it was not reason enough to discontinue the use of the rabbits for the practicals (36.2% before; 40.4% after). The students' expectations prior to participating in the practicals and their opinions upon completion revealed that they though that with the university farm they learned 60% more than without its help. The majority of Agricultural Engineering students agreed that the establishment of a teaching farm in the university for the purpose of Rabbit Farming practicals significantly improved the teaching learning process and the majority of students perceived the welfare of the rabbits was not negatively affected. © Medwell Journals, 2010.
