“…Contrary to results for goats published by Kominakis et al (2000), lambing month and birth type were not found to be statistically significant for total milk yield. The effects of age on the milk production of goats were similar to data recorded by Mavrogenis et al (1984).…”

The aim of the study was to determine the frequencies of B1, B2, B3 and E alleles of the CSN1S1 gene and their effects on milk yield and composition in the Saanen goat breed. Milk samples were collected to identify milk composition with Fourier transform ınfrared (FTIR) spectroscopy. The polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method was used to characterize the alleles of CSN1S1 gene. The allelic frequencies of the B1, B2, B3 and E alleles were 0.927, 0.073, 0.390, and 0.272, respectively. B1 and B2 alleles did not affect milk yield and composition. B3 allele had significant effects on protein, fat, total solid (TS), solid not fat (SNF), casein and lactose percentages, but not on lactose yield. E allele significantly influenced fat and TS percentages of milk in the Saanen goat breed. The protein (3.58%), fat (3.83%), TS (12.06%), SNF (8.60%) and casein percentages (2.80%) were higher in B3/B3 goats than in B3/NB3 (NB3: non-B3) and NB3/NB3 goats. For E allele, NE/NE (NE: non-E) goats displayed higher fat (4.06%) and TS (12.42%) percentages of milk than their E/E and E/NE counterparts. As a result, the potential for improving milk composition by selecting for B3 and E allele may be significant in Saanen goats. ______________________________________________________________________________________

An investigation of ribosomal protein L10 gene in autism spectrum disorders

et al. 2009

Background: Autism spectrum disorders (ASD) are severe neurodevelopmental disorders with the male:female ratio of 4:1, implying the contribution of X chromosome genetic factors to the susceptibility of ASD. The ribosomal protein L10 (RPL10) gene, located on chromosome Xq28, codes for a key protein in assembling large ribosomal subunit and protein synthesis. Two non-synonymous mutations of RPL10, L206M and H213Q, were identified in four boys with ASD. Moreover, functional studies of mutant RPL10 in yeast exhibited aberrant ribosomal profiles. These results provided a novel aspect of disease mechanisms for autism -aberrant processes of ribosome biosynthesis and translation. To confirm these initial findings, we re-sequenced RPL10 exons and quantified mRNA transcript level of RPL10 in our samples.

“…In contrast, other authors have indicated that there was no signifi cant effect of breed on cheese composition, sensory scores, and fatty acid concentrations except for that of oleic acid (Soryal et al, 2005). The number of lactations had a signifi cant effect on the volume of goat milk production and composition (Browning et al, 1995;Crepaldi et al, 1999;Goonewardene et al, 1999;Kominakis et al, 2000;Prasad and Sengar, 2002), the same effect being found for the stage of lactation (Zeng and Escobar, 1995;Prasad and Sengar, 2002). The yield in cheese making was higher when milk from the last stage of lactation was used in comparison with production levels for cheeses produced from midlactation milk (Soryal et al, 2005).…”

Milk yield in goats was infl uenced by environmental conditions connected with the calendar year. Daily milk production was observed to decrease with progressing lactation, while an increase was observed in SCC, as well as percentage fat and protein contents, while the lactose content in milk decreased. No signifi cant infl uence was found of birth type, number of kids born or reared on the qualitative and quantitative parameters of milk yield and lactation duration. Goats in their fi fth and further lactations produced over 15% milk less compared with fi gures recorded in a mediumsized fl ock (248.9 and 2942.3 ml, respectively). Goat milk contained almost 67% more somatic cells (log 6.099 and log 5.877, i.e. 1260 × 10 3 and 755 × 10 3 cells/ml).
