There are two main sources of water that is used for water supply such as ground water and surface water. Both of them are fed by precipitation water in order to stay stable for providing consumption requirements. Thus, only one drop of precipitation water should not be wasted so storm water management practices come to light. Two of the mostly known storm water management practices are low impact development (LID) which works with nature to manage stormwater at place closer to its source and green infrastructure which uses natural processes to provide infiltration and evapotranspiration or reuses runoff on the generation area. There are many LID practices that have been used to adhere to these principles such as bio retention facilities, rain gardens, vegetated rooftops, rain barrels and permeable pavements. Green infrastructure can be used in wide range of landscapes in addition to more traditional stormwater control systems to support the principles of LID. In this research, definition and main features of LID and green infrastructure was investigated, main practices used for implementation of these methods were reviewed and two methods were compared according to their benefits.","PeriodicalId":17430,"journal":{"name":"Journal of Veterinary Advances","volume":"253 1","pages":"251-257"},"PeriodicalIF":0.0,"publicationDate":"2016-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77613044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both benign and malignant tumors may occur in the dog, and according to histological criteria, approximately 50% of the tumors are malignant. Mammary gland tumors tend to be heterogeneous in their pathological characteristics and clinical behavior. Different hormones and growth factors play a key role in the development of this neoplasm, however, the mechanism by which they influence tumor growth and their possible prognostic value are still under study.

In order to assess the level of adaptation of these animals after a decade of breeding, this study aimed to evaluate the production of milk and resilience of these cattle in breeding farm of Kpinnou in Benin. Data were collected on 107 Girolando cattle including 34 cows. These animals were reared in a semi-improved breeding system based on the use of natural and cultivated pastures as well as an intake of food supplements. The Girolando cows produced 1485.19 liters of milk over 11-month collection period resulting in 4.82 liters of daily milk which represents 49.91% of the total daily production. During this period, the lactation increased depending on weeks with a peak (5.92 liters/day) in the 20th week. The effect of calving season was observed on the daily milk production (p < 0.05). The average milk collected was 5.32 liters/day for cows that calved during the big rainy season, 4.72 liters/day for cows that had parturition in the long dry season and 4.31 liters/day for those calved in short rainy season. Moreover, Kpinnou’s breeding farm is facing various diseases and particularly the permanent cattle infestation by ticks, which limit the milk production. Faced this situation, commercial dust mite killers are used against ticks. Antibiotics (Oxytetracycline, Peni-procaine) are administered to cattle in cases of mastitis or lumpy skin etc. Due to the high cost and the dubious efficacy of these veterinary products in addition to the probable deposits of drug residues in milk, the use of medicinal plants would be an alternative to explore. In addition, knowledge of the effect of the season will help to partially improve milk production of Girolando cow in breeding farm of Kpinnou.","PeriodicalId":17430,"journal":{"name":"Journal of Veterinary Advances","volume":"64 1","pages":"1269-1281"},"PeriodicalIF":0.0,"publicationDate":"2016-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80629550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Information on the prevalence of haemoparasites in small ruminants in Lafia, Guinea Savannah zone of Nigeria is scarce. Our study therefore aimed at determining the prevalence of haemoparasites of small ruminants in this area based on the parasite species, sex, age and breed. Seventy Two and 32 blood samples were collected over a time from goats (69.2%) and sheep (30.8%) respectively at the abattoir and examined for haemoparasites, using standard parasitological techniques. Overall, 21 (20.2%) of the small ruminants were infected with haemoparasites. Of these, haemoparasitic infections occurred in 23.61% and 12.5% of the goats and sheep examined. Anaplasma (13.5%), Babesia (4.8%) and Trypanosoma (1.9%) species were the commonest genera of haemoparasites observed in both goats and sheep. In the goats, 27.7% of the males were infected, while the haemoparasite infections occurred in 16% of the females. One (5.6%) and 3 (21.4%) of the male and female sheep respectively were infected. The prevalence of haemoparasites occurred more in the older goats and sheep, with the infection being higher in the adult goats (30.4%) than in the younger (11.5%) ones. Similarly, the infection was higher in the adult (18.2%) than in the younger sheep from which no infection was observed. According to the breeds of the goats, infections were more prevalent (26.2%) in the West African Dwarf (WAD), followed by the Kano Brown (21.7%) and Sahel (14.3%), while the prevalence rates were 40%, 9.1% and 6.3% in the Uda, Yankasa and Balami breeds of sheep respectively. The moderately high prevalence of haemoparasites recorded among small ruminants slaughtered for meat in Lafia, may suggest a preponderance of their vectors and therefore, calls for increased sustainable strategic measures of control.","PeriodicalId":17430,"journal":{"name":"Journal of Veterinary Advances","volume":"13 1","pages":"1251-1257"},"PeriodicalIF":0.0,"publicationDate":"2016-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75379995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Radiography is the most accurate diagnostic tool to evaluate limb deformities. However, despite the accuracy, availability, and cost-effectiveness of this tool only a few conformational studies evaluating the equine carpal morphology have been published. Consequently, the established parameters are insufficient to represent this complex joint. Dorsopalmar view (DP) is the most relevant radiographic view to assess carpal deformity. This study identified a consistent equine carpal DP view and developed reliable and repeatable carpal parameters. Twenty forelimbs from 11 adult horses of different breeds and ages were used. Forelimbs were cut at the distal radius and mounted in an extended position, then radiographed using digital radiography. The DP for the carpus at zero° (ZDP) was defined and established using two landmarks. Specific radiographic features were selected as landmarks for developing carpal parameters. Establishing any parameter was based on an ability to identify its landmarks consistently. Repeatability of identified parameters was tested with each radiograph measured twice with an interval of at least one month. Ten carpal morphometrical parameters were developed. The study provided a base for measuring carpal conformation using radiographs.","PeriodicalId":17430,"journal":{"name":"Journal of Veterinary Advances","volume":"115 1","pages":"1258-1268"},"PeriodicalIF":0.0,"publicationDate":"2016-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80580816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several phenotypic characteristics along with egg quality traits Hisex brown were studied. Three hundred cage and Three hundred litter reared hens were randomly selected. Feed and water were available ad libitum. Eggs were sampled in three age periods, from 20 to 26 weeks, 37 to 43 weeks and 54 to 60 weeks of age. No observable difference was found in plumage color, beak color, shank color, comb color, comb type and egg color in both rearing system. Significant (P<0.05) difference was found in shank length, egg weight and body weight and in cage rearing system it was 3.32±0.16, 59.44±0.42 and 1851.60±11.93, respectively where  in case of litter system it was 3.19±0.01, 61.14±0.45 and 1849.10±33.90, respectively. Egg quality characteristics were affected by rearing system and age. Egg weight, yolk weight and percentage increased with the hens’ age in both systems, but Egg shape Index decreased with age. The highest egg weight (61.14±0.45g) was found in litter rearing whereas highest yolk percentage (28.12±0.17%) was found in cage system at the final observation.
