A protocol of callus induction in fenugreek (Trigonellafoenum-graecumL.) from 8 20 days old in vitro grown cotyledons node explants cultured on Murashige and Skoog (MS) and B5((Gamborget al., 1958) media supplemented with different types and concentrations of growth regulators were tested in order to obtain the best callus formation. Two auxin types, αnaphthalene acetic acid (NAA), and 2,4-dichloro-phenoxyacetic acid (2,4-D) at four concentrations(0.5, 0.1, 1.5, and 2.0 mgL-1) with (0,0) as control in the two media were used in this study .The objective of this study was to determine the effect of different concentration of two types of auxins 2,4-D (2,4Dichlorophenoxy acetic acid) and NAA (Naphthalene acetic acid), on callus induction using cotyledons and hypocotyls explants of T.foenum –graecum. 100 percentage of primary callus induction rate and 2.5 callusing index were achieved on MS medium containing 2mg/l ,2,4-D hormone hypocotyls explants .The maximum value of callusing index (2.8) was obtained from MS medium containing 1.5 mg/l ,2,4D using hypocotyls and cotyledons explants. The maximum callus formation observed in the MS media containing 2.0mg/l NAA was 3.9±o.o8 in hypocotyls segment. The callus was compact in cotyledons and variable in hypocotyls segments and the colour is creamy.

A total of twenty four rabbits of mixed breeds aged 10 12 weeks and weighed between 900 – 1000g, were used in an experiment to determine the effect of feeding varying dietary levels of water spinach (Ipomoea aquatica) leaf meal on reproductive parameters and organ weights of male rabbits. The rabbits were randomly allocated into four dietary treatments, T1, T2 T3 and T4 containing 0%, 5%, 10% and 15% of water spinach leaf meal respectively. Feed and water were served ad libitum throughout the 8 weeks experimental period. At the end of the feeding trial, 3 rabbits per treatment were slaughtered and their reproductive organs were carefully dissected out and separated into different components. The testicular morphometry and cauda epididymal sperm characteristics were evaluated. The result showed no significant (P> 0.05) effect of diet on testicular morphometry and sperm characteristics. No significant (P>0.05) effect of diet was also observed on the internal organ weights of the male rabbits. This result shows that water spinach meal can be included up to 15% in rabbit diets without adverse effect on testicular morphometry and sperm quality of male rabbits.

The aim of this study is to evaluate the prevalence of respiratory infections of viral origin in equines .In this perspective we have researched ant viruses antibodies in equine’s arteritis in 95 horses of different breeds, Arab-Barb and Barb, all stationed in the region of Khenchela (Kais),located in the north east of Constantine. The animals are prealably recognized, upon a clinical exam, in a good health. They have received a diet containing barley and hay. They are of different sexes and their age is varying between 2 and 10 years old. The equines play an important socioeconomic role. In several rural areas, equines are regularly used as a tensile force for the animal traction cultivation and transport of persons and goods. They thus contribute widely to the increase of agricultural production and the improvement of socio economic conditions of rural populations. The results demonstrate that among the 95 serums tested, 25 were positive (33, 33 percent).to the reaction serum seroneutralization. These results are discussed in relation whith those observed by other authors. Key-words: Horse, arterits virus, serum neutralization, epidemiology.

The present study is a part of the helminthological study conducted on ruminants of Ladakh for the time period of one year. In the present study impact of diet of the host and intensity of the parasite on Morphology of a Cestode (Moniezia expansa) was taken into consideration for which postmortem examination of slaughtered host animals belonging to different age groups and of either sex feeding on different diets were carried out and the parasite/s recovered were processed and were subjected for the study of morphology and morphometry. It was observed that diet and intensity was having a relation with morphology and morphometry of the parasite. In case of higher intensity the size of parasite was comparatively small as compared to the specimens with low intensity, so was the case with respect to diet of the host it was observed that the parasites recovered from the host animals which feed on highly nutritive food were larger in size as compared to those specimens recovered from the hosts which feed on average or below average food. The parasite being reported for the first time from this region has been briefly redescribed with some intraspecific variations.

A cross sectional investigation was conducted on the major causes of kids’ mortality in Adami Tulu Jiddo Kombolcha district from May 2009 to June 2010 to determine the mortality rate and to identify the potential causes of kids’ mortality in Arsi- Bale kids. A combination of multistage and purposive sampling techniques was used to select the study areas while simple random sampling was adopted to select experimental goats. The result revealed that from a total of 536 kids born over 12 months period about 22.4% (n=120) kids were died. Internal parasite assessment was conducted to see the infection level of parasites infection both on adult and kids of Arsi- Bale goats. Accordingly fecal sample was directly collected from the rectum of the experimental animal and its result showed that from a total of 39 adults and 158 kids fecal sample collected 59.6% ( n=118) was positive and 40.4% (n=80) was negative. The types of internal parasites mostly observed on goats of the study sites were identified as Strongly (90.5%), Monesia (23.3%), Coccidian (8.6%), Fasciola (1.7%) and Ascaris (0.9%). From the positive fecal samples, 51.5% (n=61) is highly infected, 19.5. %( n=23) moderately infected and 28.8 % (n= 34) had low infestation. Diarrhea, diseases and/or internal parasites were responsible for death of kids. Therefore, systematic control of internal parasites and diseases and periodic vaccination of goats against the identified diseases should be in place to improve productivity of goats for economic return.

The recovery of dates downgraded as a fermentation medium for the production of extracellular catalase by Aspergillus phoenicis K30 was studied. Analysis of the chemical composition of pulp and kernel flour of dates showed that the pulp had a considerably greater carbohydrate content compared to the kernel (84 vs 2.93% respectively). However, the kernel flour was richer in nitrogen (0.68% vs 0.34), mineral elements (3.63 vs 1.28%) and in essential fatty acids C18: 2 vs C18: 3 than the pulp flour. The soluble extract of the date flour showed that sugars solubilised at 90% consisted of sucrose, fructose and glucose. Therefore, this extract, being an important source of carbon and energy, was used in the current study as a fermentation medium (after supplementation with 20% of corn steep) for the production of extracellular catalase by A. Phoenicis K30. During the course of this fermentation, the biomass was estimated at 18.6 g / L after 72 h of culture, while the maximum concentration of extracellular catalase (47.5 U / ml) was reached at 96 h of fermentation. The mycelium obtained in pellet form is suitable for industrial exploitation of this process.
研究了凤凰曲霉K30生产胞外过氧化氢酶的发酵培养基中枣渣的回收。对大枣果肉和果仁粉的化学成分分析表明，果肉的碳水化合物含量明显高于果仁(分别为84%和2.93%)。籽粒粉的氮含量(0.68% vs 0.34)、矿质元素(3.63 vs 1.28%)和必需脂肪酸(C18: 2 vs C18: 3)均高于果肉粉。枣粉的可溶性提取物表明，90%的可溶性糖由蔗糖、果糖和葡萄糖组成。因此，作为碳和能量的重要来源，本研究将该提取物作为a .

Eggs are very nutritious and healthy, both egg white and egg yolk have high biological value. Egg albumen, also called egg white contains a viscous 10 % solution which consists of minerals, peptides and proteins in water. These proteins have high nutritional value for humans due to their specific amino acids composition. In addition, the egg white has specific functional properties in food processing like foaming and stability properties. Major functional properties of whole egg are stability, emulsification, foaming and gelling ability. Whole egg is also applied as colorants. These nutritional properties of egg are applicable in bakery foods, mayonnaise products, salad dressings, confections, ice cream, pastas and many convenience foods. Powdered egg can be used in several preparations during processing of food in place of using liquid egg. Egg powder from spray drying has a better structure as compared to the powder from foam mat drying. Hence, powder from spray drying process can be utilized as an essential ingredient in preparations of cakes, custards, noodles and some of the confectionery products.
