In the first trial, 30 ewe lambs of the Sarda breed (initial mean live weight 16.4±1.3kg) were divided into three groups of 10 animals each and maintained

I dati della produzione giornaliera di latte di 4183 bufale sono stati analizzati con quattro modelli lineari della curva di lattazione tra i più comunemente utilizzati per i bovini da latte. L'adattamento di tutti i modelli alle curve medie di gruppi omogenei di animali è risultato

The coding region of the acetyl-CoA carboxylase alpha (ACACA) gene, which plays an important role in de novo fatty acid synthesis, had been investigated, but no non-synonymous mutations have been reported. In this study, the genomic regions encoding the three promoters of the ACACA gene were directly sequenced in 264 sheep of three different breeds, and 10 SNPs were identified. Allele frequencies of most SNPs significantly differed (P = 0.05-0.0001) between breeds. The SNPs that potentially altered either gene regulatory elements or putative binding sites of transcription factors were made evident through in silico analysis. The association analysis with milk traits, performed for one SNP of PIII (GenBank AJ292286, g.1330G>T), showed a significant allelic substitution effect (+0.33%, P < 0.0001 and +0.35%, P < 0.01) in the Altamurana and Gentile breeds respectively. Because this SNP was located in the binding site of the paired box protein transcription factors, which was shown to function as an efficient promoter element, and because PIII transcripts are expressed in the mammary gland, the SNP in PIII of the ACACA gene might affect the variation of fat content in sheep milk.

The allelic substitution effect, upon these FA, was estimated for a number of polymorphisms, that are located within 9 candidate genes known to

The hematological profile of 67 Holstein cows was assessed for 6 wk around calving. The DNA of the cows was genotyped at 6 polymorphic loci within the leptin gene, and 7 haplotypes were reconstructed. Significant haplotype substitution effects were found, for haplotype 1, on total white blood cell count for 2 wk around calving (+0.70 10(3)/μL, P = 0.05; +1.38 10(3)/μL, P = 0.0001); on neutrophil cell count in the first week after calving (+0.94 10(3)/μL, P = 0.001); on lymphocyte count during the 3 wk before and the first week after calving (+0.32 10(3)/μL, P = 0.05; +0.27 10(3)/μL, P = 0.03; +0.26 10(3)/μL, P = 0.04; +0.34 10(3)/μL, P = 0.01); on red blood cell count during the last week before calving and wk 1 and 2 after calving (+0.21 10(6)/μL, P = 0.02; +0.23 10(6)/μL, P = 0.01; +0.20 10(6)/μL, P = 0.03); on mean corpuscular volume (-1.35 fL, P = 0.01; -1.29 fL, P = 0.002; -1.18 fL, P = 0.004; -1.09 fL, P = 0.008; -1.23 fL, P = 0.003; -1.31 fL, P = 0.003); and on mean corpuscular hemoglobin (-0.37 pg, P = 0.05; -0.38 pg, P = 0.02; -0.39 pg, P = 0.01; -0.34 pg, P = 0.03; -0.40 pg, P = 0.01; -0.40 pg, P = 0.01) during all 6 wk analyzed. Significant haplotype substitution effects, but opposite those of haplotype-1, were found for haplotype-2 on white blood cell count (-1.10 10(3)/μL, P = 0.01; -1.30 10(3)/μL, P = 0.002; -1.09 10(3)/μL, P = 0.01) and neutrophil count (-0.82 10(3)/μL, P = 0.02; -0.95 10(3)/μL, P = 0.005; -0.92 10(3)/μL, P = 0.01). Haplotype-3 influenced red blood cell count (-0.23 10(6)/μL, P = 0.03; -0.28 10(6)/μL, P = 0.01; -0.34 10(6)/μL, P = 0.002) during the last 2 wk before and the first week after calving, and also, with effects evident only in wk 3 and 2 before calving, mean corpuscular volume (+1.38 fL, P = 0.03; +0.97 fL, P = 0.05; +1.08 fL, P = 0.05), mean corpuscular hemoglobin (+0.58 pg, P = 0.02; +0.38 pg, P = 0.04; 0.51 pg, P = 0.01), and red blood cell distribution width (-0.56% P = 0.02; -0.47%, P = 0.05). The current study provided evidence that several polymorphisms in the leptin gene play a role in the variability of hematological variables during the peripartum period, and might be used as genetic markers for improving the immunological conditions of dairy cows in critical productive periods.

Variant alleles are: G/T at 1330 bp, C/G at 1338 bp and C/T at 1430 bp. Frequencies of the variant alleles were calculated and chi-squared analysis of the differences in allele frequency between breed pairs was performed. Allele frequencies of the Sarda breed differ significantly from the other considered breeds.
