We conducted two studies to determine the effect of gender, gonadectomy (GDX) on growth and plasma cholesterol levels in pigs. In experiment 1, five sham-operated and five GDX female Landrace pigs (26 kg) were allowed to have free access to water and feed up to market weight (approximately 100 kg). Body weight and feed consumption were recorded biweekly, and daily body weight gain, daily feed i...

A correlation between the exocrine pancreatic function and growth has been previously demonstrated in growing pigs but the data are inconsistent. This was investigated by studying the growth performance of pigs with exocrine pancreatic insufficiency (EPI) at different ages and maintained under similar conditions. Twelve 7 week old (10.5+/-1.3 kg) weaners, and twelve 16 week old (43+/-5 kg) grow...

Data were recorded on 7,434 Norwegian Landrace boars born from 2008 to 2013. Data was provided from the boar test station of the Norwegian Pig Breeders’ Association. Feed consumption in the test period was registered together with carcass traits assessed by computer tomography. The data were analyzed with an animal model with lean meat (kg) and fat (kg) included as covariates through fixed and ...

F-strain Mycoplasma gallisepticum (FMG) may alter reproductive performance in layers through its effects on lipid metabolism. Therefore, the influences of 1.5% supplemental dietary poultry fat (PF) and FMG infection on the early performance of commercial egg-laying hens were determined. Birds were either sham- or FMG-inoculated at 12 wk, and experimental diets were initiated at 20 wk of age. Bo...

This experiment was carried out at the College of Agriculture University of Salahaddin Erbil. To study the effect of water supplementation with propolis on local quail performance, some physiological and immunological characteristics at 42 days old. A total of one thousand fifty (1050) hatched local quail eggs that obtained from the project of Al-Rashedia for Agriculture Researches Center in Mo...

To assess the effects of creep feed consumption on individual feed intake characteristics and performance of group-housed weaned pigs, 16 litters (149 piglets) were fed a commercial creep feed (3,040 kcal NE/kg, 15.2 g lysine/kg) supplemented with 1% chromic oxide. Another five litters (48 piglets) were not given access to creep feed (no-feed). Piglets were weaned at 28 d after birth. On d 18, ...

This field study assessed the efficacy of a probiotic based on viable spores of Bacillus subtilis C-3102 (Calsporin; Calpis Co. Ltd., Japan) on the health status and productivity of sows and their litters through 2 full, sequential reproductive cycles from service of the first cycle to weaning of the second cycle. Fifty-six sows were allocated to 2 experimental groups, an untreated control (T1)...

A study was conducted to evaluate the effects of an artichoke extract on broiler production performance traits by comparing the results of two inclusion rates in broiler diets from 0 to 21 days of age. A total of 2880 day-old male broiler chicks was randomly assigned to 36 floor-pens and raised from 1 to 42 days of age. The CONTROL group received a comsoya meal basal diet. In the treatment diet...

The control of mycotoxins is a global challenge not only in human consumption but also in nutrition of farm animals including aquatic species. Fusarium toxins, such as deoxynivalenol (DON) and zearalenone (ZEN), are common contaminants of animal feed but no study reported the occurrence of both mycotoxins in fish feed so far. Here, we report for the first time the occurrence of DON and ZEN in s...
