Strains of coagulase negative staphylococci (CNS) are the main bacteria species causing infection of the mammary gland in dairy cows, goats and sheep (Silanikove et al., 2014a). Recently, Tomazi et al. (2015) published a paper showing that apart from a modest increase in somatic cell count, infection with CNS had no effect on milk yield and milk composition of the infected glands in comparison ...

Dairy goat production is an emerging enterprise, which has a lot of potential for poverty alleviation, improved nutrition, and increased income for the poor and can play a role in contribution towards Kenya’s development plan. Inadequate information on prevalence of subclinical mastitis and antibiotic sensitivity are some of the challenges facing this industry. This study was carried out in dai...

Under tropical condition the BCS may influence the feed intake and metabolism leading to variation in economic parameters. This study investigated the BCS as a regulator of milk yield (MY) and composition (MC) in dairy animals. A total of 154 animals, comprising Azakheli (AZ) and Nili-Ravi (NR) buffaloes, Holstein Friesian (HF), Jersey (JC), Sahiwal (SW), Achai (AC) and crossbreds (XB) cattle a...

Dairy goats are one of the most utilized domesticated animals in China. Here, we selected extreme populations based on differential fecundity in two Laoshan dairy goat populations. Utilizing deep sequencing we have generated 68.7 and 57.8 giga base of sequencing data, and identified 12,458,711 and 12,423,128 SNPs in the low fecundity and high fecundity groups, respectively. Following selective ...

A cross-sectional study based on planned sampling was carried out to determine flock-level risk factors associated with Toxoplasma gondii antibody prevalence in dairy goat flocks in a semiarid region of northeastern Brazil. Serum samples from 975 adult dairy goats from 110 flocks were examined by indirect immonufluorescent antibody test (IFAT), using cut-off point at 1:64 dilution. From the 110...

This study aims to determine the effect of litter size and mother weight on dairy goat milk production. The research method uses survey method, data collection is carried out by purposive sampling with criteria Kaligesing goats that have been lactation as many 100 tail. variables analyzed were identity farmer, size, production weight. Data analysis was descriptive simple correlation analysis. r...

Genetic evaluations of US dairy goats are calculated annually by USDA from records that are available through Dairy Herd Improvement programs and the American Dairy Goat Association (ADGA). The number of does in test plans used in genetic evaluations was 11,273 during 1999; participation in linear appraisal programs during 1999 was 3784 does, a decrease from the mean of 4285 does over the last ...

The influence of caprine arthritis-encephalitis (CAE) virus infection on the population of peripheral blood leukocytes in goats was evaluated. For this purpose two groups of adult dairy female goats were formed. The experimental group consisted of 17 goats, which had been naturally infected for many years. The control group comprised 29 non-infected goats, which originated from CAE-free herd. A...
