This is the first report about natural Dermatophilus congolensis infection in Turkey. Presumptive and confirmatory diagnoses were made based on clinical signs and the demonstration of the bacteria frorn scab material by direct microscopic examination and by culturing the organism on bacteriological media and identifying it by conventional methods such as biochemical reactions. The study was car...

∗ E-mail: [email protected] ABSTRACT This study was applied on a total number of 40 native breed lambs from Dakahlia governorate, their ages being ranged from 5 to 26 days, in order to declare the effects of nutritional muscular dystrophy as an oxidative stress in lambs and the effect of vitamin C administration in enhancing the treatment of Nutritional Muscular Dystrophy (NMD), decreasing...

Prematurely delivered lambs were treated with radiolabeled natural surfactant by either tracheal instillation at birth and before the onset of mechanical ventilation, or after 23±1 (±SE) min of mechanical ventilation. Right ventricular blood flow distributions, left ventricular outputs, and left-to-right ductal shunts were measured with radiolabeled microspheres. After sacrifice, the lungs of l...

A study was carried out to assess the bioavailabilities of several forms of vitamin E in lambs. A total of 40 lambs was allotted to eight dietary groups of five each and supplemented or not daily for 60 d with equimolar amounts of different vitamin E compounds as follows: 1) control, no supplemental vitamin E, 2) DL-alpha-tocopheryl acetate, 3) D-alpha-tocopheryl acetate, 4), D-alpha-tocopheryl...

On studying the enzymatic pro®le of serum muscle speci®c enzymes (ALT, AST, LDH and CPK) in two sheep ̄ocks one free while the other was endemic with stiff lamb disease it was found that: (1) Serum muscle speci®c enzymes levels were signi®cantly increased in lambs of the endemic ̄ock when compared with those from the non-endemic one. (2) Vitamin E and selenium administration was followed by sig...

Gastrointestinal parasitism is one of the most important challenges facing low chemical or organic livestock production systems but also conventional farmers as resistance to anthelmintics becomes more widespread. Young twin-born and reared lambs were challenged for 5 days (Experiment 1) or trickle infected with parasites (Experiment 2) and not weaned (Expt. 1. only) or early (8 and 7 weeks) or...

Thirty six male Chall lambs (four-month old and 26  ±1.5 kg body weight) were randomly assigned into four treatments (nine lambs per treatment) to study the effect of Powerfeed® (a commercial mixture made from wheat processing by-product and wheat bran) on weight gain, feed intake, feed conversion ratio, serum sodium and potassium concentration and urine pH. Lambs in control group were fed with...

RATIONALE Respiratory syncytial virus (RSV) infection in preterm and newborn infants can result in severe bronchiolitis and hospitalization. The lamb lung has several key features conducive to modeling RSV infection in human infants, including susceptibility to human strains of RSV such as the A2, Long, and Memphis Strain 37 (M37). In this study, the kinetics of M37 infection was investigated i...

background: the role of thyroid hormones has been recognized in normal embryo development many years ago. these hormones also affected the development of reproductive organs and their activity. objectives: this study was conducted to investigate the effect of inducing hypothyroidism by propyl-2-thiouracyl (ptu) on lambs testicular histomorpho-logy and plasma testosterone concentration. methods:...

Abnormalities of the lymphatic circulation are well recognized in patients with congenital heart defects. However, it is not known how the associated abnormal blood flow patterns, such as increased pulmonary blood flow (PBF), might affect pulmonary lymphatic function and structure. Using well-established ovine models of acute and chronic increases in PBF, we cannulated the efferent lymphatic du...
