In October 2004, 41 goats > 2 years old from a Saanen dairy goat herd located in Purranque County, 10th Region, Chile, were sampled and tested for paratuberculosis. While collecting samples it was observed that several goats were thin and emaciated. One goat was sufficiently debilitated to warrant humane euthanasia. This animal was brought to the Veterinary School at the Universidad Austral de ...

In this study, 15 polymorphic microsatellite markers were used to analyze the genetic structure and phylogenetic relationships of 6 dairy goat breeds in China, including 4 native developed breeds and 2 introduced breeds. The results showed that a total of 172 alleles were detected in 347 samples of the dairy goat breeds included in this study. The mean number of effective alleles per locus was ...

Thirteen Saanen and Saanen crossbred female goats, between the ages of 6 months and 7, years were presented to the clinic, College of Veterinary Medicine, Sudan University of Science and Technology, for sonographic pregnancy diagnosis. Transabdominal ultrasound was performed using 3.5 MHz probe which revealed non-viable fetuses as judged by absence of heart beats and movements. Twelve goats wer...

Caseous lymphadenitis (CLA) is an acute, pyogenic, and contagious disease of goat that imposes considerable economic losses for farmers, and it is caused by Corynebacterium pseudotuberculosis Herein, we introduce the genome sequencing of C. pseudotuberculosis strain KM01, isolated from an abscess of a Saanen goat from Kunming, China. The genome contains 2,198 genes, the total length of the gene...

The purpose of this study was to evaluate the effectivity of melatonin in addition to light treatment (exposure to 2 hours of light during the night = a long-day photoperiod) to modify the breeding season of Saanen and cross-bred milk goats and to compare the difference between the breeds. Twenty-two Saanen and 22 cross-bred does were randomly divided into 3 treatment groups. Group 1 (controls)...

Casein genes directly control milk protein of animals. CSN1S1 (αS1-Casein) and CSN2 (β-Casein) influence on fractions. Genetic polymorphisms gene at g.12164G>A locus g.8913C>A were identified by PCR-RFLP technique. Animal samples pure dairy goats providing PE (5 hds.), Saanen (8 hds.) their crosses Sapera (50% Saanen, 50% PE) (51 SaanPE (75% 25% (3 from IRIAP goat station. Allele frequenc...

The objective of this study was to examine the effect of donor breed on pronuclear-stage embryo yield to be used for DNA microinjection in a transgenesis goat program. Twelve Canindé and twelve Saanen goats were heat synchronized using a progestagen-cloprostenol treatment. Forty-eight hours before the sponge removal, superovulation was induced with a total administration of 4.4 mg/kg bodyweight...

Kisspeptins, the product of the KISS1 gene, play an essential role in the regulation of reproductive functions, acting primarily at the hypothalamic level of the gonadotropic axis. We detected polymorphisms of the goat KISS1 gene in 723 individuals from three goat breeds (Xinong Saanen, Guanzhong, and Boer) by DNA pooling, PCR-RFLP, and DNA sequencing methods. We cloned the promoter sequence of...
