2018
Rouabhi, Amar | Laouar, Abdelmalek | Mekhlouf, Abdelhamid | Dhehibi, Boubaker
Conservation agriculture is a concept which defines different farming systems. Its implementation depends on soil properties, climate and socio-economic considerations. Since two thousands, no-till technology; which is one facet of the conservation agriculture has begun to take place in the high plains of Sétif province-Algeria. Its adoption is facing several problems of socio-economic and technical issues. This work monitored the track of no-till adoption within a sample of 28 farmers during two years 2014 and 2016. During 2014 farmers were supported financially and technically through a subsidy program that aimed at the support of conservation agriculture via no-till technique. In 2016, the subsidy program has ended; hence, farmers have no longer incentives. Multivariate statistical analyses were performed to diagnose the evolution of no-till adoption and behavior’s farmers between the two periods. In 2016, results showed an increase of no-till area, even though, the drop of the number of adoptive farmers by 71%. The main reasons for adopting no-till according to the adoptive farmers were the minimization of farming operation costs and saving time. However, the major impediments facing no-till adoption; were the rise of weeding charges and the concern of weed infestation especially by bromus.sp, which is a vigorous prevalent weed, which locally developed some pesticide’s resistance. Also, the excessive use of pesticides may be considered as an environmental reason for no adopting no-till.
Afficher plus [+] Moins [-]Examination of Relationships Between Some Biochemical and Oxidative Stress Traits by Canonical Correlation Analysis in Broiler Chickens
2018
Sıddık Keskin | Emine Berberoğlu | Şenay Sarıca
Canonical correlation analysis is a multivariate method to examine the relationships between two (X and Y) sets of variables when all measurements are obtained from same broilers. Canonical correlation analysis aims to obtain new variables called as canonical variates formed by linear combinations of the original variables for each set and by maximizing the relationships between two set. The purpose of this study is to examine the relationships between 8 biochemical traits (Aspartate Aminotransferase (AST), Albumin, Triglyceride, Total Cholesterol, Low Density Lipoprotein (LDL) cholesterol, Glucose, Total Protein and Alanine Aminotransferase (ALT)) and 4 oxidative stress traits (total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI), lipid peroxide (LPO)) in broiler chickens. As a result, the correlation between the first canonical variable pair was found 0.594.

Oils constitute a major source of plant-based protein. A major limitation to optimal oil consumption in sub-tropical region is fungal infestation and consequent mycotoxin contamination. Ten refined and eight unrefined vegetable oils were randomly purchase from open markets and screened for microbial contamination using standard microbial procedures. Twenty six fungi isolates were obtained from the vegetable oil samples, the isolates were identified as Aspergillus fumigatus (43.0%), Mucor (17.9%), Saccharomyces cerevisiae (10.7%), Aspergillus niger (7.1%), Aspergillus flavus (7.1%), Penicillium spp (7.1%), Aspergillus oryzae (3.6%), Mucor (17.9%) and Rhizopus spp (3.6%). Five out of the ten refined vegetable oil samples had no fungal contamination. A. flavus and A. oryzae were absent in all the refined oil samples while A. niger was absent in all the unrefined oil samples. Isolation of mycotoxigenic fungi such as Aspergillus spp. is of vital importance in the food industry. Education and training of processors and consumers is recommended.

Bu çalışmanın amacı ülkemizde yetiştirilen kültür ırkı süt sığırları ile bazı yerli sığır ırklarında Büyüme Hormonu Reseptörü (GHR) gen çeşitliliğinin belirlenmesidir. Çalışmada hayvan materyali olarak 468 Siyah Alaca (SA), 280 Jersey, 93 Boz Irk, 86 Yerli Kara (YK), 64 Doğu Anadolu Kırmızısı (DAK) kullanılmıştır. Popülasyonların GHR geni için FIS değerinin negatif bulunduğu Jersey, SA (Samsun), SA (Bursa) ve DAK’larda heterozigot bireylerin fazlalığı görülmüştür. Bu değerin pozitif bulunduğu Boz ırk ve YK’da ise homozigot bireyler daha fazladır. GHR lokusu bakımından Hardy-Weinberg oranından beklenen sapmalar YK hariç diğer popülasyonlarda önemli bulunmuştur. Genel popülasyon bazında ise %14 oranında heterozigot bireylerin fazlalığı ve Hardy-Weinberg oranından sapmalar önemli bulunmuştur. Popülasyonlar arasında genetik uzaklık değerleri ise 0,0004 ile 0,1881 arasında belirlenmiştir. Kümeleme analizi sonucunda iki temel kümenin şekillendiği görülmüştür. Bu kümelerin ilkinde Jersey ile YK bir alt kümede Boz ırkla genetik olarak yakın bir şekilde gözlenmiştir. Diğer ana kümede ise SA (Samsun) ve DAK bir kümede ve bu kümeye ise SA (Bursa) daha yakın bulunmuştur. Sonuç olarak ülkemizde yetiştirilen beş farklı sığır ırkında genetik olarak kümeleme analizi ile sınıflandırmaları yapılırken bu ırkların GHR geni açısından göstermiş oldukları genetik varyasyon da belirlenmiştir. Dolayısıyla bu ırklar açısından verim özelliklerinin artırılmasına yönelik bir genetik ilerlemenin mümkün olduğu söylenebilir.
