Crossbred Hampshire–Duroc boars were compared to purebred Hampshire, Duroc and Landrace boars for seven semen characteristics and for reproductive performance under competitive double mating. A total of 14 boars were represented: three Hampshire–Duroc, three Hampshire, three Duroc and five Landrace. Significant breed of boar effects were observed on semen volume (P <.01), sperm concentration (P <.10), concentration score (P <.05), morphology score (P <.10), live–dead rate score (P <.05) and total semen score (P <.01). Landrace and Hampshire–Duroc boars produced more than twice the volume of semen produced by purebred Hampshires and Durocs. Hampshire, Duroc and Hampshire–Duroc boars had greater sperm concentrations and concentration scores than Landrace. Hampshire–Duroc boars ranked highest for morphology and total semen scores, but lowest for live–dead rate score. When double-mated to Landrace sows, breed of boar had no significant effect on conception rate but significantly affected (P <.05) percent of litter sired. Hampshire, Duroc and Hampshire–Duroc boars sired almost twice as many pigs as the Landrace.

Abstract. Hafizuddin, Karja NWK, Praharani L, Setiadi MA. 2021. Breed and age effects on concentration of adiponectin and reproductive performance in Anglo Nubian, Etawah grade and its crossbred bucks. Biodiversitas 22: 1112-1119. The purpose of this study was to evaluate the effect of differences in breed and age on reproductive performance and adiponectin and testosterone production in Anglo Nubian, Etawah grade, and crossbred (Anpera) bucks. A total of 12 bucks with four individuals of each breed were used. This study collected five data points from each buck regarding adiponectin, testosterone, and reproductive performance (libido and semen characteristics). Data were analyzed with factorial analysis of variance and Duncan's test. The result shows that adiponectin concentration between breeds was significantly different (P <0.01). There were also significant differences (P<0.05) in adiponectin concentrations based on buck age. There were also significant interactions with adiponectin concentrations (P <0.01). Furthermore, testosterone concentrations showed significant differences based on breed (P <0.05) and age (P <0.05). There were also significant age-breed interactions affecting testosterone concentrations (P <0.01). Libido and semen characteristics had no significant differences based on breed and age group, and no significant age-breed interactions (P> 0.05). The heterosis effect on adiponectin concentration (48.05%), testosterone concentration (27.68%), libido (-0.61%), semen volume (-1.93%), sperm motility (0.49%), sperm normal morphology (0.18%), and sperm concentration (0.00%) was measured. In conclusion, there is a significant effect of breed, age, and age-breed interactions on the concentration of adiponectin and testosterone in bucks, and both of these variables have a high heterosis effect on crossbred bucks.

The aim of this work was to evaluate the efficiency of the intrauterine insemination (IUI) in swine, considering the conception rate, farrowing rate, litter size (alive born pigs). For the IUI, the females had been insemination at 24 and 48 hours after the estrus detection, and the inseminating doses of 500 million, 1 billion, 1.5 billion and 2 billion spermatozoa in 20 mL extender had been used. The procedure of catheter insertion through the cervical canal was successfully performed in 97.9% of the females. The conception rate was 6.3% in the IUI. The farrowing rate in IUI was 87.2% but the farrowing rate was 100% for the sperm concentration of 500 million. Regarding the number of born pigs and alive born pigs observed in females inseminated with IUI, no significant difference was observed (p > 0.05). The concentration of 500 x 10(6) spermatozoa in 20 mL extender in the intrauterine insemination resulted in an optimal reproductive performance.

The aim of the study was to investigate the effect of dietary supplementation of vitamin E on the semen characteristics of the Markhoz goats. Eighth bucks were randomly allocated into two groups, and received two different diets: unsupplemented diet (control) and supplemented diet with vitamin E (0.30 g/Kg DM). All experimental diets were formulated according to AFRC 1998. Semen was collected at 14-days intervals from June 17, 2006 to September 2, 2006 (non-breeding season) using artificial vagina. Semen characteristics were evaluated including semen volume, sperm concentration, live sperm percentage, percentage of motility and progressive motility. This characteristics were evaluated at two weeks intervals the trial. The total number of spermatozoa per ejaculation was calculated by multiplication of the semen volume with sperm concentration. Sperm motility was also analyzed by placing a sample on pre-warmed (37 º C) microscope slide covered with a cover slip, and examined under a high power microscope at a magnification × 200. Data was analyzed using proc MIXED in SAS program. Significant effect (P≤0.05) of the week (sampling time) was observed for all the parameters except for semen volume. Vitamin E supplementation significantly improved (P≤0.05) total number (Control: 263.7 ×107±17.506 vs. Vit E: 320.95 ×107±17.506) and sperm concentration (Control: 301.79 ×107±13.657 vs. Vit E: 386.57 ×107± 13.657), motility (Control: 77.27% ±0.89 vs. Vit E: 82.6% ±0.89) and progressive motility (Control: 4.208 ±0.138 vs. Vit E: 4.229 ±0.138), percentage of viability (Control: 80.57% ±0.89 vs. Vit E: 85.9% ±0.89). The results suggested that the supplemental Vitamin E may improve the semen quality and fertility in the Markhoz goats.

We investigated the supplementation effects of Acacia mearnsii tannin extract (TE) and encapsulated tannin extract (ETE) on reproductive performance and oxidative status of South African Mutton Merino rams. We also observed the season effect on the testicular measurements. Thirty rams were divided into five groups: 0.0 g TE (control), 1.5 g TE, 3 g TE, 1.5 g ETE, and 3 g ETE supplemented daily for 16 weeks transiting from autumn to winter. Bodyweight and testicular measurements were recorded biweekly. Semen and blood samples were collected weekly during the last five weeks of supplementation. Results showed that the increase in the ETE from 1.5 to 3 g increased the testicular length and sperm concentration, as well as decreased the percentages of low and non-progressive spermatozoa (p<0.05). Simultaneously,the increase in the TE from 1.5 to 3 g decreased semen volume and elevated the percentage of abnormal sperm (p<0.05). The results suggest that the encapsulation of TE affords the maximum benefit of the TE on the sperm quality. Treatments did not affect the hormonal and oxidative status. Testicular measurements were significantly higher in autumn compared to winter. The plasma level of cortisol significantly correlates negatively with sperm motility, viability, and acrosome integrity.

An experiment was undertaken to determine the conception rate of native sheep by using Artificial Insemination with liquid ram semen. The semen was collected from ram using artificial vagina and the was stored in a refrigerator (4°C) for three days. The volume of semen was extended with egg yolk citrate diluter. A total of 63 ewes were inseminated with stored liquid semen collected from 15 rams by AV method. The total number of spermatozoa, live-dead, normal-abnormal, sperm motility and the pH was observed regularly. The average semen volume per ejaculate was 0.76-1.00ml and the sperm concentration was 2.37x109 - 4.30x109 per ejaculate. The number of normal spermatozoa and the pH was almost similar irrespective of days of storage. Number of live spermatozoa and the sperm motility were reduced with the increasing age of semen. The average conception rate (%) was obtained as 63.61, 61.90, 52.38 and 47.61 with sperm in zero, 1st, 2nd and 3rd day storage respectively.

In poultry breeding program the success of artificial insemination (AI) is highly influenced by  the quality of semen. The aim of the present research was to evaluate the variations in semen characteristics of three phenotypes of chicken of the same specie raised in Akko, Nigeria. A total of 9 cocks from threedifferent phenotypes; Red feathered (n = 3), White feathered (n = 3) and Black feathered (n =3). The semen was evaluated for macroscopic (i.e. semen volume and colour) and microscopic (i.e. sperm concentration, motility and morphology) criteria after being collected by abdominal massage method. There were phenotypes variation (P > 0.05)effects on semen motility, number of live/dead sperm and sperm abnormalities. No differences(P>0.05) were observed on volume, colour, concentration, mass motility and pH of semen. The observed sperm progressive motility was ranged from 90.5 ±1.21% to 95.09±0.82%. The White feathered strain had the highest sperm progressive motility (P<0.05)and highest value for live and normal sperm (93.5±0.63% and 87.90±0.25%), while the black feathered had the least and (92.4±0.73% and 85.5±0.50%) respectively. The Red feathered strain had the highest value for both dead and sperm head defect (9.2±0.33%and 7.0±0.52%). Whilst, the Black feathered strain scored the highest percentage of both sperm tail and neck defects with values ranged from 11.4±0.43%to 14.2±1.08% and 19.4±0.53% to 23.6±0.69%, respectively. This study suggests that there are large variations present in semen characteristics of different phenotypes of cocks; White feathered strain is likely have better semen characteristics compared to Red and Black feathered strains. Therefore, White feathered strain can potentially be used in artificial insemination (AI) for chicken production and improvement.
