Tetraclinis articulata is an endemic, medicinal and aromatic species of the cupressaceae family with an economic importance. The objective of our study is based on the morpho-metric characterization of a 210 individual sample from seven populations distributed in five regions in western Algeria: Tlemcen (Ain fezza (Yfri forest), Ain Ghraba (Ahfire forest), Beni Snous (Zarifate forest)), Ain Temouchent ( Madagh 2 forest) , Oran (the Virgin forest) , Relizane ( Zemmora forest) and finely Sidi Bel Abbes (Tenira forest) using eight morphological traits :Circumference of the tree (CRF),The tree height (TH),The tree crown (TCR), The length of primary branch (LgB1),The length of secondary branch (Lg B2),The length of the needles(LgNd) which were statistically studied using the R software. Phenotypic diversity was determined by the Shannon-Weaver diversity index (H') at different levels. The estimated H' showed a large phenotypic variability for different traits with a mean of 0.90. The results of the multiple correspondence analysis (MCA) and hierarchical clustering (HCA) showed a clear distinction between the populations. The extraction of essential oils was done for all populations; the yield of essential oils from the trees of the Beni Snouss population was higher than the other populations which is very important for future economic perspectives and we all so found that there is a negative correlation between the yield of essential oils and The length of the needles (LgNd) which can be used to identify the subjects with the best performance.

The common pomegranate (Punica granatum) is a perennial tree, drought tolerant, able to growin poor and alkaline soils. It has beenconsidered as one of the oldest and most famous tree. Because of its richness in nutrients andversatile uses, it gained a huge economic interest. This fruit tree has been the subject of significantgenetic improvement globally. However, in Algeria no such improvement program has been undertaken. In order to developnew varieties that match the needed criteria, and to preserve, restore and enhance the diversity of existing genetic material, this study was conducted for morphometric analysis for the identification and characterization of the common pomegranate in the wilaya of Tlemcen.

Duck keeping is a very important sector in resource-constrained families as it provides for family proteins and income and other social needs. The present study was carried out to determine the influence of gender on livestock breeding practices of duck farmers in Nasarawa State, Nigeria. A total of 100 duck keepers (36 males and 64 females) were randomly sampled. Primary data were collected through individual structured questionnaire administration. Chi-square (χ2) statistics were used to compare categorical variables based on gender. Arithmetic means of continuous variables between gender were tested using the T-Test. Rank means were also calculated for between-gender comparisons of the continuous variables. On the choice of traits of preference (body size, body conformation, mothering ability, survival, heat tolerance, disease resistance, birth interval, plumage color, fertility, hatchability, egg number and size, meat taste, ease of sale, and cultural significance) for breeding, the non-parametric Kruskal–Wallis test followed by Mann–Whitney U tests (P ≤ 0.05) was used for comparison between gender. Age of respondents, household size, and personal savings were significantly (P<0.05) higher among the male than female farmers. Flock size was also higher (40.33±7.06 vs. 22.70±2.55; P<0.05) in farms owned by males compared to their female counterparts. However, both sexes ranked income, meat, egg, and cultural/religious significance the same as reasons for keeping ducks. The number of foundation stock and feed quantity per day (kg) were higher (P<0.05) in male flocks. Productivity measure in terms of the number of death of ducks was significantly (P<0.05) in the direction of male farmers (0.03±0.03 vs. 0.23±0.08). The ranking of the traits preferred in the choice of breeding stock of ducks was the same for both sexes except for cultural/religious significance which the female farmers rated lower (1.14 vs. 1.56; P=0.030). Breeding programs and development interventions targeting the improvement of indigenous ducks should focus on gender equality to boost production and stimulate sustainability.
在资源有限的家庭中，养鸭是一个非常重要的部门，因为它为家庭提供蛋白质、收入和其他社会需求。本研究的目的是确定性别对尼日利亚纳萨拉瓦州养鸭农民饲养牲畜方式的影响。随机抽取100名养鸭人，其中公鸭36名，母鸭64名。通过个人结构化问卷调查收集原始数据。基于性别的分类变量比较采用χ2统计。性别间连续变量的算术平均值采用t检验。对连续变量的性别间比较也计算秩均值。在繁殖偏好性状(体型、体型、育母能力、成活率、耐热性、抗病性、出生间隔、羽色、育性、孵化率、蛋数和大小、肉味、易售性、文化显著性)的选择上，性别间比较采用非参数Kruskal-Wallis检验和Mann-Whitney U检验(P≤0.05)。男性农民的年龄、家庭规模、个人储蓄显著高于女性农民(P<0.05)。鸡群大小(40.33±7.06 vs. 22.70±2.55)较高;P<0.05)。然而，男女都把收入、肉、蛋和文化/宗教意义列为养鸭的原因。公鸡基础存栏数和日饲料量(kg)较高(P<0.05)。以死亡鸭数衡量的生产力指标在雄性农户方向上显著(P<0.05)(0.03±0.03∶0.23±0.08)。在选择种鸭时，除文化/宗教意义上女性农民的评分较低(1.14比1.56;P = 0.030)。以改良本地鸭为目标的育种计划和发展干预措施应注重性别平等，以提高产量和促进可持续性。

To further understand productive characteristics and explore economically valuable signs of the wool’s camels in Algeria, we studied the wool’s fineness of a population of 27 adults female camels. The studied breeds are Ouled sidi cheikh, Targui and Reguibi at the level of the Wilaya of El Bayadh in El Keither commune and the Wilaya of Naama in Naama commune. We took wool samples from different parts of the she-camel’s body: the head, the hump and the tail. The measurement of each wool fiber have been done with a binocular loupe glass equipped with an acquisition software, the collected data have been then analyzed using Rstudio software. The results showed how the diameter of the studied she-camels can vary according to different breeds going from super fine for Ouled sidi cheikh and Reguibi she-camels (9.03-11.7 µm and 9.5-10.2 µm, respectively) to fine for Targui she-camels (21-22.8 µm). This study can suggest the application of Ouled sidi cheikh and Reguibi’s wool in the textile industries for the production of sweaters and baby clothes, and the application oh Targui’s wool in shawls and rugs

The consumer necessity for a good quality of olive oil in terms of its lipid and phenolic profiles is demanded to preserve a good health and to combat illnesses. The conformity of olive oil with the International Olive Council standards requires the determination of certain chemical parameters including free acidity, saponification and peroxide indices. Our study was based on a comparative evaluation of chemical quality indices and extraction of phenolic compounds from different samples of olive oil of different durations of storage, from different regions of Algeria and with different preparations. The most recent olive oil sample presented the least acidity (1.88%) and saponification index (185.32 mg of KOH/g of oil). However, the sample conserved for five years revealed the highest quantities of total phenolics (0.56 ± 0.02 mg GAE/g oil) and flavonoids (0.174 ± 0.019 mg CE/g oil). Different results were collected comparing samples of olive oil from different regions from Algeria. Acidity percentages were ranged from 0.7 to 3.1%, peroxide index from 8 to 53meqO2/Kg of oil and saponification number from 166.61 to 201.11 mg KOH/g of oil. Yields of phenolic extraction results revealed percentages from 0.11 to 0.24%. The traditionally prepared olive oil presented the best quality with an acidity of 1.01% and a saponification number of 187.10 ± 13.68 mg KOH/g oil. Whereas, the industrially prepared one exhibited the lower number of peroxide with 8.30 ± 2.88 meqO2/ kg oil. The quality of olive oil was influenced by time, geographical region and mode of extraction. Conserved olive oils may be destined for the manufacture of soaps or the extraction of phenolic compounds

Polydactyly is one of the most co mmon congenital limb dysplasia frequently observed in fa rm anima ls and varies in e xpressivity. He rein, a preliminary investigation on inheritance and types of polydactylyin one hundred and four (104) ducklings produced by seven (7) mating g roups (MGs) of different genotypes werereported. These ducklings were produced from non descript random bred population of Muscovy ducks in the Netherlands and data generated were ana lysed with descriptive (percentage and bar chart) and infe rential statistics{Chi-square (χ2)}. The resultsindicated that irrespective of the genotypes of the parents, polydactyl gene (Po) had inco mplete do minance and penetrance in the ducklings; however, the observed frequencies of polydactyly was not significantly (P>0.05) d ifferent fro m the e xpected proportions in all M Gs. Fu rther analysis of expressivity of the gene revealed prevalence of bilateral e xpression (97.18% ) co mpared to the unilatera l inc idence (2.82% ).The phenotypic e xpression of the mutant gene was classified into sixteen (16) distinct types and about one-third (31.82%) of polydactyl ducklings exp ressed type 5 polydactyly. In addition, dosage effect of Poand twin polyphalangeal(PoTP) genes exerted influence on incidence of polydactylism and observed polydactyly types. The highest number of polydactyly type was e xpressed by progenies of homozygous polydactyl parents. Conversely, PoTPgene was antagonistic to the expression of polydactylyand the incidence of polydactylysim was highest among ducklings of non-twin polyphalangeal parents.

The goal of this study is to characterize the diversity of the Algerian south donkey population, characterize its biometric variability, and determine the evolutionary relationships of this animal with its congeners at various latitudes. A total of sixty-six adult asses, distributed on the level of three wilayas from where eleven body measurements, six body indexes developed in horses and adapted to donkeys were calculated, and seven phenotypical characters were retained for this study. Measurements Lsi, HG, TP, LH, LE, Pc, LT, LO, LQ, LaT, Tm, Pv1, Pv2 are respectively: 98.05±10.46; 105.31±6.59; 188.88 ±8.61; 32.62±4.61; 27,17±4.41; 15.52±2.42; 50.92±3.82; 24.07±3.59; 39.24±14.30; 23.174±3.09; 41.82±3.52; 171.83±32.76; 145.83±27.62. Those information are used to compute 6 body indexes. According to body and profile indexes we deduce that our animals were medial linear and small (PI ≈ 1,08 and BI ≈ 0,82), they could not even bear their own weight loads (CI > 1), their heads were long (HI ≈ 0,45< 1) with a square body shape (LI ≈ 0,93< 1,10). Donkeys’ thoracic development was average according to (CD≈ 1,13). All parameters except the LE, PC, TM for the regions showed a significant difference on examined body measurements (p>0,05). On the phenotypical characteristics, a factorial analysis of the multiple correspondences revealed two main components that account for 48,90 and 44,26 % of total inertia, or 93,2 %. These percentages are related to the dress color, the head, the members, the hairs, the muzzle, and the belly. This research revealed significant phenotypic differences that should be included in the specie’s characterization and conservation efforts.

The study assessed genetic diversity of four Nigerian sheep populations namely; Balami, Yankasa, Ouda and West African Dwarf (WAD) making use of blood sample. Extracted DNAs were used to study polymorphism at the β-lactoglobulin gene locus using RLFP-PCR process. Results revealed the percentage polymorphic locus was 100% while Shannon’s information index, observed homozygosity, expected heterozygosity, unbiased expected heterozygosity and fixation index were 0.656, 0.516, 0.464, 0.477 and -0.075, respectively. The gene flow (Nm) for all the population was estimated to be 7.65. The pairwise Fst was low and within the range of 0.0004(between Balami and WAD) to 0.0520 (between Balami and Yankasa). Variation within and between the populations of sheep shows that a large proportion of the observed variance (98% at p < 0.01) occurred within the breeds while only 2 % of the variance (p < 0.01) was contributed due to differences among the breeds. The nearest genetic distance was between the Balami and WAD (0.001) and between Ouda and the WAD (0.001). Phylogenetic analysis revealed three clusters. The present study showed that effort should be made to prevent the wearing away of the genetic make-up of the sheep populations considering the negative fixation index.

Animal genetic resources (AnGR) are important to all future developments and adaptations. The concept has an international obligation to conserve certain characteristics of domestic animals for sustainable and future use. Characterization of indigenous Muscovy duck (Cairina moschata) would provide information for AnGR and also aid in conservation of ducks for future use. Two hundred (200) Muscovy ducks obtained from five (5) geographical locations in North central Nigeria were characterised using qualitative traits, physiological parameters, blood profile and quantitative traits. The results showed that 52.50, 54.00, 51.50, 50.00, 45.00 and 35.50% of the Muscovy ducks in the study area had black colour with respect to their general body plumage, shank, bill, web, eye, and bean, respectively. 50.00% were of horizontal body carriage, 90.50% had palmate web type, and 95.00% had no crest while 62.50% had caruncles. Sexual dimorphism existed between male and female with drakes having significantly (p<0.05) higher values compared to ducks in all the quantitative traits measured. Physiological parameters were not significantly (p>0.05) different according to sex and origin of the Muscovy duck studied. Comparison of the ducks by origin showed significant (p>0.05) differences in body weight, shank diameter, keel and wing length, and also in white blood cells, lymphocytes, red blood cells and mean corpuscular haemoglobin concentration, platelets and glucose. The information obtained here can serve as a guide on decisions concerning the conservation and development of selective breeding strategies for improvement of Muscovy ducks in the studied area.
