The effect of two dietary
levels of L-carnitine and vegetable fat powder on broiler breeder fertility,
hatchability, egg yolk and serum cholesterol and triglyceride was studied.
Two hundred fifty female and twenty five male (Classic Hubbard parent
stock) were distributed randomly in five groups of 50 with five replicate
of 10 females and one male. Two levels of L-carnitine 0, 60 ppm (for
females) and 0, 500 ppm (for males) and vegetable fat powder (0, 1.5%)
and a diet with high lysine and methionine (0.3%) fed for both of male
and female within one of treatment were used in a complete random design
of treatments. The parameters as hatchability, fertility, egg weight,
albumen height, Haugh unit, color of yolk, shell thickness, shell strength,
yolk weights, egg yolk and serum cholesterol and triglyceride were measured.
No significant differences were observed in external and internal egg
quality. Supplemented diet with L-carnitine had effect on hatchability
(P< 0.05) and fertility (P< 0.01). L-carnitine had no effect on egg production
except on fifth and sixth weeks (P< 0.01). None of experimental diet
had no effect on male serum cholesterol, serum triglyceride in both
sex and total yolk cholesterol but L- carnitine had effect on female
serum cholesterol (P< 0.05). L- carnitine had decreased egg yolk cholesterol
(mg/gr) (P< 0.05). Yolk weight increase in response to dietary supplementation
of L-carnitine(P< 0.05) and L-carnitine content of egg yolk increase
with L-carnitine supplementation (P< 0.05). |

To investigative the effect of dietary L-carnitine on ostrich sperm quality, a research was conducted in a completely randomized design consisting of 3 treatments and 4 replicates. The total numbers of birds used in this trail was 12 African black neck male ostrich. The experimental rations were prepared using the different levels (0, 250 and 500 ppm). The metabolizable energy, protein and the nutrient of these rations were similar. In order to study semen volume, sperm motility, live sperm percent, sperm count and abnormal sperm percent, after one month adaptation, semen collected at the beginning of every three month. The results of statistical analysis of data obtained indicated that there were significant effect of L-carnitine on semen volume (p<0.01), sperm motility, live sperm percent, sperm count (p<0.05) but L-carnitine had no significant effect on abnormal sperm percent. |
