Ergot contains numerous poisonous substances (alkaloids), which upon ingestion by animals may lead to poor growth rate, decreased feed consumption and poor feed efficiency. The effect will depend on the age or physiological stage of the animal, and the amount consumed. Results obtained in this study indicate that the consumption of diets containing more than 0.10% high alkaloid ergot by weanlin...

Development of gilts that conceive early and continue to produce offspring is an objective of swine production. We investigated different patterns of growth on reproductive development and performance of gilts through the first farrowing. At 13 wk of age and 43 kg BW, 286 white crossbred gilts were penned individually and assigned to treatments: Ad lib, ad libitum intake from 13 to 25 wk of age...

Artificial illumination, including light quality, is crucial in modem broiler management. In the present study, a new, highly efficient, monochromatic light system has been developed for broilers. One hundred and eighty male broiler chicks (Anak) were divided into four light treatment groups (n = 45) in three replicates each. All birds were housed in a single room previously divided by wooden b...

the experiment was carried out in poultry experimental station belonging to nrc, cairo, egypt. a total of 120 fayoumi layers, 45 weeks old, were randomly divided into four equal groups. each group included three replicates (10 hens in each). the first group was fed the control diet containing 3.3% gram ca, whereas, the other three received diets containing 2.8, 2.6 and 2.4% gram ca, respectivel...

The objective of this study was to evaluate the effect of herbage allowance on pasture DM consumption by growing European wild boar. An additional objective was to evaluate the influence of pasture consumption on supplemental diet intake and BW gain. A previously sown grass-clover pasture was managed by cutting to obtain an herbage mass equivalent to 1,500 kg/ha DM. Areas of pasture were limite...

the effects of different dietary levels of soybean oil (2, 4 and 6%) and probiotic primalac (0, 0.1 and 0.15 %) were investigated on performance and immune system of broiler chickens from day one to day 42 of age. for this purpose, five hundred and forty day-old male broiler chicks (cobb) in 9 groups of 60 each were used. the birds of each group were divided into 6 pens of 10 birds. the experim...

this study was conducted to investigate the effect of aflatoxin b1 (afb1) on performance and egg quality in broiler breeders and the abatement of its deteriorative effect through its counteraction with herbal mycotoxin binder (hmb). thirty-six, 28-wk-old broiler breeder hens were allotted to one of the three treatments of: (1) basal diet (control),(2) control plus 500 μg kg-1 afb1 and (3) contr...

An experiment was conducted to evaluate the effect of form and particle size of feed supplemented with L- threonine on growth performance, carcass characteristic and blood biochemical parameters of broiler chickens. The experimental design was a 2 × 2 × 2 factorial arrangement of treatments evaluating two feed forms (pellet or mash), two feed particle sizes (fine or course), and two inclusion r...

Five hundred ten duck eggs of Pekin and each of Muscovy duck eggs were incubated to determine fertility and hatchability. The eggs were cleaned and stored at 18-21oC for 6 days prior to setting in the incubator. The eggs were incubated in a forced-draft electric incubator and the hatching performances were recorded. Ninety Pekin and ninety Muscovy day-old ducklings were randomly selected from t...
