Abstract

Abstract:The purpose of this study was to evaluate, under field conditions, the efficacy of an european registered bovine concentrated lactoserum (Locatim) in 3 farms with neonatal diarrhoea in calves. A total of 117 healthy Belgian Blue (BB) calves were allocated in 2 groups. Two thirds of the calves received Locatim orally immediately after birth and maternal colostrum one hour later (treated group), while control calves only received maternal colostrum. Every day during 14 days, mental status, faeces consistency, suckling reflex and hydration status of each calf were monitored. Individual blood samples were assessed for passive transfer and specific Escherichia coli antibodies against strains F5, CS31A, F17 and F41. Faecal samples from diarrheic and non diarrheic calves were analysed for rotavirus, bovine coronavirus, Cryptosporidium parvum and Escherichia coli F5. Locatim had no significant effect on the onset, duration and incidence of diarrhoea. The mean serum IgG concentration of 23.1 ± 7.8 mg/ml indicates a good IgG transfer. Only the CS31A strain titer was significantly higher in the treated group. The major identified causative agent of diarrhoea was C. parvum. In conclusion, Locatim only has a slight effect when IgG transfer is optimal, but could be justified when specific antibodies lacking in colostrum are needed.

Prevalence and Antimicrobial Resistance Profile of Escherichia Coli and Salmonella Isolated from Diarrheic Calves

“…Diarrhea is one of the major cause of mortality in newborn calves, the incidence of diarrhea in calves less than one month ranges between 15 to 20%, signifying that the greatest risk occurs during the first two weeks of life (Vandeputte et al, 2010). Calf diarrhea is a major cause of economic loss with high morbidity and mortality in the cattle industry worldwide (Kelling et al, 2002;Uhde et al, 2008;Bartels et al, 2010).…”

Immune Response, Health Status, Blood Components and Growth Performance of Suckling Calves Treated with Thymus vulgaris Extract

“…Also, the essential oils enable to breakdown the lipids of the cell membrane of the bacteria because of their hydrophobicity characteristics and leading to cell structures disturbing and making them more permeable (Sikkema et al, 1994). Several researchers indicated that plant is one of drug sources because it have antibacterial, antiviral, antifungal, antioxidant and insecticidal properties which are due to their contents of essential oils that examined as alternatives animal production by improving growing performance and the quality of derived products (Burt, 2004;Simitzis and Deligeorgis, 2011).…”

“…The first week of calf age is the most critical period of their life because it is associated with several health problems which lead to about 10% mortality rate. Diarrhea is one of the major reasons of mortality in newborn calves ( Vandeputte et al, 2010;Cho and Yoon, 2014) that affects the livestock industry globally (Tajik et al, 2012). Different bacterial infections cause diarrhea (Radostits et al, 2010).…”

“…The overuse of antibiotics in order to reduce these pathogens has led to the phenomenon of multi-drug resistant bacteria (Boskovic et There are several types of plants which are consider as drug sources because they have antibacterial, antiviral, antifungal, antioxidant and insecticidal properties due to their contents of essential oils (EOs). These plants have been examined as alternatives in animal production for improving growing performance parameters and the quality characteristics of the derived products (Burt, 2004;Simitzis and Deligeorgis, 2011). Essential oils (Eos) have therapeutic potential properties as they employed in treatment a variety of animal diseases, they act through stimulation of blood circulation, they reduce pathogenic bacterial counts and improve the immunity response by increasing the nutrient digestion and raising essential nutrients availability from intestine (Zeng et al, 2015).…”
