In this experiment six healthy adult dairy Jersey cattles and eight calves (aged 4-6 months) were selected to measure temperature of different body skin sites, rectal temperature, respiration and heart rates during summer and winter. Body sites maximum and minimum temperature in calves during summer belonged to the ear, forehead, right flank, abdomen (38.4-38.9 ˚C) and carpus (32 ˚C). This was ...

this study was done for identification of bacterial agents in calf pneumonia and determination of their antimicrobial susceptibility. bronchoalveolar lavage was done on fourteen pneumonic and seven normal holstein calves between 1-3 month old. in bacteriological examination on the fluid of bronchoalveolar lavage, mycoplasma spp. were isolated from 4 (28.6%) pneumonic calves and 1 (14.3%) health...

Animals- A total 76 ruminant calves and kids having congenital deformities were studied. Procedures- Surgical intervention for each case was carried out after proper diagnosis and post operative care with systemic an...

The objective of this study was to evaluate the effects of weaning age on dry matter intake (DMI), average daily gain (ADG), feed efficiency (FE), feed cost (FC) and benefit index (BI) of Holstein calves reared under organic farming system. Thirty two Holstein calves were divided into two treatments: early weaning (EW) vs. late weaning (LW). Calves in the both groups were provided with whole mi...

Four trials were conducted to explore possible advantages of weaning beef calves in two stages compared with the traditional method of weaning by abrupt separation. In the two-stage treatment, calves were prevented from nursing their dam for a period (Stage 1) before their separation (Stage 2). Control calves nursed from their dams until they were separated. Calf weights and behavior were recor...

AIM The present work was designed to study the incidence of obstructive urolithiasis and to apply comparative diagnosis to urine retention cases. MATERIALS AND METHODS A total of 78 non-castrated buffalo calves aging 3-11 months were included in this study, 68 calves were admitted to the Veterinary Teaching Hospital, Zagazig University, Egypt, during the study period with a history of anuria,...

Holstein calves were fed pelleted starter diets with crude protein (CP) concentrations of 18%, 22% and 24% per dry matter (DM) containing soybean meal (SBM) (SBM18, SBM20 and SBM24), respectively, for 10 weeks from 14 days of age. Another diet with a CP concentration of 18% per DM was tested using commercial xylose-soybean meal (XSB; Yasminomax) instead of SBM. Each diet was fed to 24 calves an...

Data for this linecrossing study were the postweaning growth and weight records of calves born from 1967 through 1975. The records consisted of 264 bull (M) and 263 heifer (F) straightline (SL) calves; 108 M and 100 F two-line rotational cross (2W) calves; 130 M and 102 F three-line rotational cross (3W) calves and 58 M and 51 F synthetic variety (SV) calves, all in the Hereford breed. Average ...

background: the purpose of dehorning in cattles is to decrease injuries and increase security in farms. besides breeding managements, different chemical and physical methods are used for dehorning of livestock, depending on their age, each of which has advantages and disadvantages. objectives: this study was performed to evaluate the effects of clove oil on disbudding new born calves following ...

During previous work Schistosoma antibodies and circulating antigens were detected at birth in the serum from some calves born to Schistosoma mattheei infected mothers. The objectives of the present survey were: (1) to investigate the proportion of calves, born to cows infected with S. mattheei, which have specific antibodies and circulating schistosome antigens present in their serum at birth ...
