The stillbirth rate in twins is a more sensitive indicator of environmental hazards than the stillbirth rate in singletons. Medical care or other socioeconomic factors may be more influential for perinatal survival in twin than in single deliveries. Studies have indicated that stillbirths among children in a set of multiple maternities are not independent. Models were considered assuming indepe...

Ongole cattle in smallholder farms on Java, Indonesia, have been crossed with Limousin, which is not controlled repeatedly. The character of estrus affects the success Artificial Insemination. This study aimed to determine relationship between characters before double dose artificial insemination using frozen semen sexing. research was conducted Senggreng Village, Sumber Pucung District, Malang...

Abstract Text: Genomic selection offers considerable flexibility to increase genetic trends in dairy cattle breeding, through a decrease in generation interval, an increase in selection intensity, and an increase in reliability for females and for low heritability traits. It is also an opportunity for more sustainable breeding, in terms of breeding goal and genetic variability. With a shorter g...

In the last century, agriculture has seen the introduction of innovating reproductive biotechnologies that have permitted this field to grow significantly. In the early 20th century, introduction of semen cryopreservation and artificial insemination has propelled animal agriculture worldwide with the possibility to import and export in a biosecure way genetics from different species. Then, with...

Sixty-five chromosomal preparations from bisected bovine embryos were examined and 43 embryos (66.2%) with metaphase plates were observed; however, only 25 embryos (38.5%) were sexed. Fifteen of the bisected embryos sexed by chromosomal analysis were transferred to each of the 15 recipients, and 5 recipients became pregnant. Female calves were born on December 28, 1985, August 2, 1986 and July ...

From 2012 to 2018, 223 180 Montbéliarde females were genotyped in France and the number of newly increased at a rate about 33% each year. With female genotyping information, farmers have access genomic estimated breeding values their herd carrier status for genetic defects or major genes segregating breed. This combined with coancestry, can be used when planning matings order maximize expected ...
