Ultrasonographic Imaging of Reproductive Organ in Indonesian Native Chicken Hen (Gallus Domesticus)
Hen’s native chicken reproductive organ health status evaluation is important for raising Indonesian native chicken in order to support protein supply for people demand. This study aimed to discover the images of Indonesian hen’s native chicken reproductive organ using ultrasonography. There were 18 hens that used in this study and divided into two groups, 15 hens for brightnessmode ultrasonogr...
متن کاملReproductive Efficiency of Cows of Different Sizes
The effect of cow size on reproduction has become of in, respectively. The hip heights of the small, medium greater concern in recent years as a result of marked and large frame-size bulls used were 53, 55 and 57.5 in, increases in cow size in both purebred and commercial respectively, at 2 yr of age. The bulls were selected from herds and the extremely large effect of fertility on the within t...
متن کاملBayesian inference of genetic parameters for reproductive traits in Sistani native cows using Gibbs sampling
This study was undertaken to estimate the genetic parameters for some reproduction traits in Sistani beef cattle. The data set consisted of 1489 records of number of insemination, calving, and insemination dates in different calving was used. Reproduction traits including calving interval (CI), gestation length (GL), days open (DO), calving to first service (CTFS), first service to conception (...
متن کاملApproaches to increase reproductive efficiency in artificially inseminated dairy cows
Infertility has been linked to numerous factors in high producing dairy cattle in the last decades. The detection of estrus continues to present difficulties and, although progress has been made in regards to estrus synchronization and artificial insemination, the reproductive performance of dairy cows has not improved substantially. Moreover, in warm countries, summer heat stress is a major fa...
متن کاملGenetic potential and reproductive performance of Whitebacks – Polish native breed of cows
The investigations covered all the cows included in the genetic resources conservation programme and in the registers of the Whiteback breed. The animals are predominantly maintained in small farms in the eastern part of Poland. The genetic variation of these cows was characterized on the grounds of the studies of 11 loci of the DNA microsatellites. In the 11 analysed loci, total 93 alleles wer...
