Organic zinc supplementation in hens has been reported to improve fertility. The current study
evaluated the effect of organic zinc supplementation in hens on fertility after insemination with
cryopreserved semen. White Leghorn rooster semen was cryopreserved using 4%
dimethylsulfoxide (DMSO) in 0.5ml French straws. Different semen parameters and fertility were
assessed in post-thawed samples. White Leghorn hens were divided into 5 groups with 30 birds in
each group. Each group was further divided into six replicates of five birds each. The control group
was fed a basal diet, other groups were fed with a basal diet supplemented with 40, 60, 120 and
160 mg/kg organic zinc (zinc proteinate). After two weeks of feeding, insemination was done in
hens per vagina using thawed semen (200 million sperm/0.1 ml). Basal group hens were
inseminated with fresh or cryopreserved semen and served as control groups. Sperm motility, live
sperm, and acrosome intact sperm parameters were significantly (P < 0.05) lower in post-thaw
semen samples. Fertility from cryopreserved semen was significantly (P < 0.05) lower and organic
zinc supplemented hens had fertility similar to that of cryopreserved semen inseminated into basal
diet group hens. In conclusion, organic zinc supplementation in hens does not improve fertility
after insemination with 4% DMSO cryopreserved semen.
