This experiment was conducted to investigate the effect of pre-pubertal plane of nutrition on the skeletal growth, lamb mortality, insulin-like growth factor 1 (IGF-1) concentrations, quantity and quality of colostrum produced in ewe lambs. A total of 40 clinically health Kurdish female lambs (30±8.6 d and weighing 10.2±3.4 kg) were randomly allocated to one of two experimental diets in pre-wea...

To determine the value of pre-pubertal plan of nutrition on reproductive performance, hormonal concentrations and milk production in ewe lambs, a total of 40 clinically health Kurdish female lambs (30±8.6 d and weighing 10.2±3.4 kg) were randomly allocated to one of two experimental diets in pre-weaning period: high quality diet (HQD) (HQD, 2.50 Mcal ME/kg dry matter (DM) and 148 g CP/kg DM) or...

BACKGROUND: Pre-pubertal nutrition managements are considered essential for animal health, optimizing production and reproductive performance in livestock. OBJECTIVES: In this study, the effects of dietary low and high energy and protein provisions on body growth, blood metabolites and inherent safety index were investigated in pre-pubertal Kurdish female lambs. METHODS: We fed 40 healthy Kurdi...

this study was carried out to assess the effects of alfalfa hay level and replacing corn grain by other grains in starter on daily feed intake, average daily gain (adg) and feed efficiency (fe) of pre and post-weaning dairy calves during the pre and post-weaning periods. for this purpose, a database meta-analysis used in the present study. statistical analyses were performed using proc mixed in...

A study was conducted to evaluate effects of age at weaning on various growth characteristics and stress measures of Zandi lambs. The lambs were weaned at 45 and 90 days of age. The body weights and average daily gain (ADG) were monitored during the experimental period and 5 months of age. Cortisol, glucose, blood urea nitrogen (BUN) and lamb behavior (agitation, vocalization) were recorded bef...

Introduction  Mechanical ventilation may be lifesaving intervention,It can be associated with complications,Thus,successful weaning is constitutive.One of the factors which is  important in successful weaning is  method of weaning. It is shown that  weaning is conducted successfully by using Spontaneous Breathing Trial (SBT) through T-piece and pressure support (PS) ventilation.But few studies ...

BACKGROUND In recent years non-invasive ventilation (NIV) as become a valuable therapeutic option in exacerbations of patients with chronic pulmonary obstructive disease. Although widely used there is a paucity of information on weaning from NIV. OBJECTIVES We aimed to describe the performance of a weaning protocol based on progressive periods of NIV withdraw. METHODS During a one year peri...

We determined the impact of creep feed provision and type on pre- post-weaning growth performance piglets. At 2 wk post farrow, litters (n = 50) were given no or provided a simple feed, complex both until weaning at ∼28 d. Creep regardless type, resulted in increased (P < 0.05) piglets final week pre-weaning immediate post-weaning, which was not maintained end nursery period. Piglets showed ...
