Objective: Diacylglycerol acyltransferase 1 is a microsomal enzyme that catalyzes the final step of triglyceride synthesis. The objective of this project is to check out the polymorphism at the exon 8 region of DGAT1 gene using PCR-SSCP technique in Iranian water buffaloes (Bubalus bubalis). Recent activities have shown that a significant association between lysine at amino acid positi...

Promotion and protection of breastfeeding is an important strategy in prevention of Vitamin A (Retinol) deficiency in childhood. Breast milk retinol’s allows us the chance to reach the maternal nutritional status and go over infant status. This study aimed to know the retinol and fat content in mature breast milk from Novo Cruzeiro’s population, Brazil. It was analyzes 63 samples of breast milk...

This work presented economic weights (EWs) calculated for Holstein cattle raised in Slovak dairy productions using a bio-economic approach. EWs are calculated for alternatives with (A) and without (B) market quota. Both alternatives included three market payment systems of milk (base price per milk value was corrected according to content of fat, protein and somatic cells). Marginal EWs for mil...

The present study investigated the effects of supplementing soybean oil (SBO) and sunflower oil (SFO) on the performance of early lactating Awassi ewes, growth of their sucking lambs and on the concentration of total fatty acids in milk and blood of suckling lambs. One hundred and twenty five ewes were randomly assigned into five equal sized treatment groups involved; a control total mixed rati...

The aim of this study is to show the importance and significance of goat milk . Goat is known as poor man’s cow .It play a vital role in the socio-economic structure of rural poor. Goat milk contains higher amount of Ca, Mg and P than cow and human milk but vitamin D, vitamin B12 and folate contents are less. Although fat and protein is somewhat low in goat milk than cow milk, but there is a no...

BACKGROUND Gyr cows are well adapted to tropical conditions, resistant to some tropical diseases and have satisfactory milk production. However, Gyr dairy herds have a high prevalence of subclinical mastitis, which negatively affects their milk yield and composition. The objectives of this study were (i) to evaluate the effects of seasonality, mammary quarter location (rear x front), mastitis-c...

High-fat diet (HFD) during lactation alters milk composition and is associated with development of metabolic diseases in the offspring. We hypothesized that HFD affects milk microRNA (miRNA) and mRNA content, which potentially impact offspring development. Our objective was to determine the effect of maternal HFD on secreted milk transcriptome. To meet this objective, 4 wk old female ICR mice w...

Milk produced at organic farms was studied to determine the β-carotene content and if an extended grazing period and organic fodder had any influence on the concentration of this antioxidant. Milk samples from 31 organic farms collected during April, June, August, November (1999) and February (2000) were analysed for the content of β-carotene by HPLC after lipid extraction and fat saponificatio...

Six groups of Sahiwal-Friesian crossbred cows, namely M50-1, M50-2, M50-3, M56, M63 and M75-1 were evaluated. In total 180 cows were used and milk collected was evaluated for composition and quality. The effect of genotypes was significant (P≤0.05) only for titrable acidity (TA) and milk yield (MY). The M50-1 had the highest milk yield per day (8.73 ± 1.65 kg) but this was not significantly dif...
