The perinatal environment plays a crucial role in programming many aspects of adult physiology. Myriad stressors during pregnancy, from maternal immune challenge to nutritional deficiency, can alter long-term body weight set points of the offspring. In light of the increasing concern over body weight issues, such as obesity and anorexia, in modern societies and accumulating evidence that develo...

The usefulness of supplementary dietary L-carnitine as an immunomodulator to increase antigen-specific antibody levels was analysed in 2-6-week-old broilers. The chickens received commercial feeds either unsupplemented (starter feed 17.8 mg carnitine/kg, finisher diet 22.9 mg carnitine/kg) or supplemented with L-carnitine (100 mg carnitine/kg added to feed). At 14 d of age, both groups were dis...

normal 0 false false false en-us x-none ar-sa background: abnormal weight gain during pregnancy increases the adverse health outcomes during the pregnancy, delivery, and the postpartum period. most of the pregnant women develop weight gain more than the recommended limits; therefore, interventions to manage such disproportionate weight gain are needed. in this paper, the design of the maternal ...

the present study was aimed to improve the reproductive performance of corriedale ewes by nutritional flushing. forty corriedale ewes were divided into four treatment groups (tc, t1, t2 and t3) with 10 ewes in each group (n=10). at the beginning of the breeding season extra feeding (flushing regime) was started for approximately 34 days such that two estrus cycles were covered. first group i.e....

an experiment was conducted in order to assess the effects of different levels of dietary canola meal (cm; 0, 10 and 20 %) and copper (0, 125 and 250 mg/kg) on performance, susceptibility to ascites syndrome and some blood metabolites of broiler chickens. during a six week period of experiment, a total of 495 male broilers (ross 308) were used in completely randomized design with a 3×3 factoria...

Effect of propylthiouracil (PTU)-induced hypothyroidism during the prepubertal period, at a dose of oneg per kg of the diet, on serum testosterone level and seminal characteristics of Fars indigenous chickens wasstudied. PTU was fed between 7th to 13th weeks of age and semen was collected at weekly intervals, starting at 21st week of age and continued for seven weeks. The effect of PTU treatmen...
