In order to compare the main locomotive problems in broilers of Cobb and Ross strains, two pens from a commercial farm in Veracruz, Mexico were used. The first pen housed 16,500 males and 16,500 females of Cobb strain and the second one 16,500 males and 16,500 females of Ross strain. Chicks were checked for locomotion problems from day one until their sale. Animals with problems were recorded and necropsies were performed to identify the pathology. Out of 1406 animals with locomotive problems (2.13% of the total), 58.9% were Cobb and 41.1% Ross (P <0.05). The frequency of locomotive problems was 2.51% for Cobb and 1.75% for Ross. Most common individual lesions were osteochondrosis (38.61%), inflamed joints with purulent contents (37.13%), and valgus (19.65%). Locomotive problems appeared since the first week, but its number increased as birds gained weight, particularly from the fourth week on. Problems occurred more in males than in females and in Cobb birds than in the Ross strain. Economic loss due to locomotion problems was higher for the Cobb strain.","PeriodicalId":17588,"journal":{"name":"Journal of Veterinary Science and Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86431900","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}

Bovine mastitis is a disorder that affects dairy farms and has a major economic impact. Most of the economic losses are the result of mastitis. Mastitis is an invasive infection that is among the most numerous and highly complicated infections in the dairy sector. Mastitis is one of the most expensive diseases in terms of production losses among animal diseases. Mastitis reduces milk production, changes milk composition, and shortens the productive life of infected cows. Farmers must concentrate on avoiding mastitis infection whilst putting in place and following a mastitis control programed. Bovine mastitis, the most significant disease of dairy herds, has huge effects on farm economics. Mastitis losses are due to reduced milk production, the cost of treatments, and culling. Major factors related to low milk yield could be low genetic potential as well as poor nutritional and managerial approaches. Most of the losses are related to somatic cell count (SCC), which is characterised by an increase in the percentage of milk. Culling costs are the costs of rearing or buying a replacement animal, mostly heifers. Overhead impacts include the replacement animals' lower milk supply effectiveness. The expense of replacing animals prematurely due to mastitis is one of the most significant areas of economic loss.","PeriodicalId":17588,"journal":{"name":"Journal of Veterinary Science and Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86656901","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}

The study was carried out at Livestock Farm Complex, College of Veterinary Science and Animal Husbandry, ANDUAT, Kumarganj, Ayodhya and nearby villages. Twenty four cattle calves were utilized to study haematological parameters that are Haemoglobin (Hb (gm/dl), Neutrophil (%), Basophil (%), PCV (%), Lymphocyte (%), Monocyte (%), TLC (103/ µl), Eosinophil (%), N/L ratio) and oxidative stress before and after disbudding in to four groups viz. control (T0), lignocaine (TL), tremadol (TT) and lignocaine+tremadol (TL-T). After medication calves were disbudded by hot iron method. The blood samples were collected for haematological parameters & for estimation of LPO (lipid peroxides) as per method described by [1] just before (0h) and after disbudding on 6h, 24h and 72h. The results showed that, at 24h, T0 group showed significantly lowest Hb (10.66±0.49%) which was statistically similar to TT and TL-T groups. At 0h, 6h and 72h means of PCV% were significantly different among treatment groups. The lowest lymphocytes (64.00±1.00) was observed in TT group at 6h. The T0 group showed significantly lowest basophil (0.00±0.00) which was statistically similar to TT and TL-T groups but significantly different from TL group at 6h. At the same interval, T0 group showed significantly lowest monocytes (4.66±0.61) which was significantly different with TL, TT and TL-T groups. At 6h, T0 group showed significantly lowest N/ L ratio (0.15±0.01) which was statistically similar to TT and TL-T groups but significantly different from TL group. At 0h, 6h and 24h LPO was significantly different among groups. At 0h, T0 group showed significantly highest (106.59±0.63) which was significantly different from TL, TT and TL-T groups. It may be concluded that no significant difference was observed in eosinophil%, TLC, neutrophil% and monocyte% counts between control and treatment groups. However, Hb%, basophil%, PCV% and lymphocyte% were significantly different between control and treatment groups. N/L ratio was significant only at 6h. Most of the cases TL-T group showed comparatively better performance. At 0h, 6h and 24h LPO was significantly different among groups.

This study is based on the first documentation of ethnoveterinary knowledge for indigestion or diarrhoea treatment in cattle on the Bilogora hills in northwestern Croatia. Data collection was conducted from 2008 until 2018, in eighteen villages of four municipalities in the Koprivni?ko-križeva?ka county, Croatia. Plant specimens were well known, in addition they were confirmed and identified by the skilled botanist. Nine plant species: flax (Linum usitatissimum L.), chamomile (Matricaria recutita L.), hazelwort (Asarum europaeum L.), broad-leaved dock (Rumex obtusifolius L.), sweet chestnut (Castanea sativa Mill.), common oak (Quercus robur L.), white willow (Salix alba L.), common mallow (Malva sylvestris L.), yarrow (Achillea millefolium L.) from 7 botanical families were documented. Decoction and herbal tea were the most common preparation methods. The most often used plants to treat mild diarrhea in cattle were chamomile and broad-leaved dock, and for hard, watery diarrhoea bark of sweet chestnut and sessile oak. The most often used plants to treat indigestion in cattle were hazelwort, chamomille, and flaxseed. Farmers used mostly leaves (about 57%), flowers and stems (more than 25%), bark (about 13%), branches, and seeds (5%) for herbal preparations.

A successful dairy farm operation requires that a large percentage of cows wean a live healthy calf every year. However, in many developing countries, a large number of calves die during the early neonatal life, this causing heavy economic loss. This is due to several infectious (bacterial, viral, and protozoal) and non-infectious factors (management around birth, colostrum management, calf housing, feeding system, hygiene, and pathogens) play an important role in calf rearing. This paper aims to review major infectious causes of neonatal calf mortality. Numerous studies have been conducted in the past from many parts of the world using both retrospective and prospective data sources to document the major causes of calf mortality. Of the infectious diseases of calves, neonatal diarrhea is a matter of major concern, and multiple etiological agents from viruses (Bovine rotavirus, Bovine coronavirus, Bovine viral diarrhea virus) from bacteria (Salmonella spp, Escherichia-coli, and Clostridium perfringens) from protozoal (Cryptosporidium-parvum) have been identified as major causes of neonatal calf mortality. Among the infectious agents, rotavirus and E. coli are mainly involved in the causation of neonatal calf diarrhea which leads to high mortality and morbidity in young calves. E. coli mainly plays its role up to the second week of life whereas, rotavirus up to the third week. Generally, early calf mortality leading to economic losses due to the cost of treatment, prophylaxis, increased susceptibility to other infections, reduced growth rates, and death of calves.\u0000\u0000Keywords: Calf Mortality; Infectious Diseases; Diarrhea","PeriodicalId":17588,"journal":{"name":"Journal of Veterinary Science and Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87420147","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}
