Abstract

In order to evaluate the effect of diet supplementation with Moringa oleifera leaf meal (MOLM) on growth and laying performances of quail in soudano-guinean zone of Cameroon, a study has been conducted in Ngaoundéré from May to September 2018. For this purpose, a total of 168 seven weeks old quails were divided into 12 comparable batches of 10 females and 4 males. Each of the four experimental diets (T0, T1, T2 and T3), formulated on the basis of the level (0, 1, 2, and 3% respectively) of diet supplementation with MOLM was randomly assigned to 03 batches in a completely randomized. Data were collected during the 16 weeks of the study on feed intake (FI), body weight (BW), body weight gain and feed conversion ratio. Weekly, after total laid eggs evaluation, 40 eggs per treatment was randomly chosen, weighed and measured. Main findings revealed that FI was not significantly affected by the diet supplementation with MOLM. Significantly higher BW and BW gain was recorded in T1 treatment compared to others treatments while they remains similar between them. The relatively heavier eggs were noted in T2 treatment while the highest (88.57 ± 2.85%) weekly laying rate was recorded with 1% supplementation. It has then been concluded that MOLM could be used as diet supplement during laying phase up to 3% for egg production and 1% of substitution seem to be the most appropriate to increase eggs laying rate while 2% is suitable to obtain heavy eggs in the soudano-guinean agro ecological zone of Cameroon.

Abstract

This study was carried out to determine the effect of dietary supplementation of Dennettia tripetala on some biochemical parameters of rats. Twenty-five rats were used and were divided in to five groups of 5 rats. Group 1 served as control while group 2-5 were fed dietary inclusion of Dennettia tripetala fruits for 28 days. After the feeding trials, the rats were sacrificed and blood was collected for biochemical analyses. The serum concentration triglyceride and glucose were significantly lowered (p<0.05) while total protein, catalase and high-density lipoprotein were significantly higher (p<0.05) in rats fed with the formulated diet. There was no significant difference (p<0.05) in the serum level of superoxide dismutase, albumin, cholesterol and low-density lipoprotein of rats fed with the formulated diet. In conclusion, the study has shown that dietary inclusion of Dennettia tripetala fruits has hypoglycaemic, antioxidant and hypolipidemic effect. Therefore, it may help in the prevention of coronary heart disease, diabetes mellitus and cancer.

Abstract

Today the aromatic and medicinal plants have gained more recognition as dietary supplements because they are characterized as natural, safe, eco-friendly, and possess many health-promoting properties, making their ongoing usage part of an emerging field at the cutting edge of science. Rosehip (Rosa canina), a medicinal plant, is widely known as a valuable source of various nutrients and biologically active substances, mostly polyphenols and vitamin C. The chemical composition differs depending on the climate, growing region, cultivation practice, maturity, soil type, harvesting and storage conditions. Over the years, significant variations in vitamins (106-967 mg/100 g), minerals (Fe 59.40-72.90 ppm; Zn 3.69-4.51 ppm; Ca 133.30-146.70 ppm), essential fatty acids (33.8% - 49.7% α-linolenic), phenols (9982 GAE - mg/100 g), antioxidants (lutein, zeaxanthin) among other bioactive components and nutrients have been reported by various researchers. Both in vivo and in vitro studies have shown that rosehip used at an appropriate dose in broilers and laying hens dietary feed, could have some beneficial effects.

Abstract

The increase search for easily available and cheaper alternative sources of proteins to meet up the increase protein demand necessitated the present study which was design to assess the effects of graded levels of jujube (Ziziphus mauritiana) seed inclusion in the diets of weaners rats. Twenty-five weaner rats were allocated into five groups of formulated diet consisting of treatment 1 - 5 in which soya bean was replaced with Ziziphus mauritiana seed at 0% (control), 25%, 50%, 75%, and 100% respectively for 3 weeks. Effects of the diets on lipid profile, haematology and serum chemistry were evaluated. Rats fed 25%, 50% and 100% Z. mauritiana had significantly higher feed intake and weight gain when compared with the normal control. All levels of inclusion tested increases the concentrations of serum total proteins and bilirubin but decreases the cholesterol and platelet counts when compared with the control. No diet related alterations were recorded for the relative organ’s ratio, aspartate transaminase, alanine transaminase, albumins, urea, creatinine, sodium, chloride, high- and low-density lipoprotein, triglyceride and hematological indices analyzed. However, seed inclusion only at 100% significantly (p<0.05) increases the total white blood cell count and relative liver weight ratio. Ziziphus mauritiana seed possess good dietary protein quality for optimal growth of rats and does not elicit any adverse effect on haematological and serum biochemical indices of organs integrity.

Results: In this sample, we noted a diversity of signs and associated pathology, a variety of digestive symptoms represented mainly by abdominal pain (59%), chronic diarrhea (51%) and vomiting (48%). Extra-digestive symptoms represented mainly by palorous skin and mucosa, delayed status and weight and stagnation of the weight with the percentages: 69%, 53% and 51% respectively. In addition, we noted biological disorders and a series associated pathologies namely: anemia (29%) and mouth ulcers (6%).

Conclusion: Childhood Celiac Disease (CD) of eastern Algeria can be expressed by a variety of digestive symptoms and gastrointestinal disorders (GI) in addition to a series of associated conditions.

Abstract

C. (Morphocarabus) rothi comptus Dejean 1831, is a endemic species of the Romania, appearing localized to some mountainous massifs of Romanian Banat and their piedmont areas (Poiana Rusca Mountains, Țarcu Mountains). Its presence in the Apuseni Mountains is doubtful, due to the lack of recent captures and to the confusion with C. (Morphocarabus) hampei diffinis Csiki 1905, morphologically like. In Banat the species occurs in two forms: szorenyensis Csiki 1908 at higher altitude (1300-2000 m) and ulrichhoffmanni Lie 1982 in hilly areas, which is distinguished by a larger size. Whatever the altitude and the ecological conditions, the period of activity is brief, spread over a month with a maximum of over two weeks. Molecular biology studies: confirm the belonging of comptus to rothi as a subspecies of her (28SRNA5 marker); suggest (concatenation COI I / cyt b) a low infra-specific variability between provenances of the szorenyensis (Rusca, Muntele Mic) and between the origins of the ulrichhoffmanni.

Abstract

Jojoba cultivation and production face the challenge of establishing ways to identify the sex at early stage of plant growth. The present study was carried out to identify sex of jojoba at the seedling stage under Sudan condition. Two DNA markers, ISSR (UBC807) and RAPD (OPG-5), were used for sex identification of jojoba genotypes: two known male and females genotypes and four unknown genotypes. ISSR marker, UBC807 was successfully amplified a unique male-specific band at 1200 bp, while RAPD marker, OPG-5 could not amplify a unique band within jojoba sex. The result clearly indicates that ISSR-UBC807 marker can be used for sex identification of jojoba at seedlings stage, a finding that could make the commercial cultivation and production of jojoba possible in Sudan.

Abstract

Digenetic trematode infections including schistosomiasis and fascioliasis have highly neglected statuses but are a menace to people in the poorest countries of the tropics, causing high morbidity and mortality in humans as well as great global losses in livestock production. This has neccesitated the widespread search for better control options for the snail vectors of these diseases. Hence, a novel drug - curcumin and nisin poly lactic acid (PLA) entrapped nanoparticles (CurNisNp) was screened for molluscicidal activity against the adults (> 2 months old) of Biomphalaria pfeifferi, Bulinus globosus and Lymnaea natalensis vector snails. Mortality was determined after 96-h of exposure at varying concentrations. The snails of the species L. natalensis were found to be the most susceptible to the molluscicide (LC50 323.6 ppm). This finding further supports the desirability of curcumin-nisin polylactic acid (PLA) nanoparticles as a molluscicide and therefore shows that it could be a good alternative to conventional molluscicides with prospects in the selective control of fascioliasis. However, more optimization of the drug could ensure a greater molluscicidal potency.
