This study aimed to identify the expression levels of some candidate genes for mastitis resistance (LTF and BRCA1), milk yield (POU1F1 and IGF-1), and milk quality (PPARγ and CSN2) in different feeding systems (pen- and pasture-based) used for Damascus goats. Milk samples were taken from all goats in both pen and pasture groups at 4 times, at the 1st, 3rd, 5th, and 7th months of the study. It was found that, compared to the pen group, the LTF and CSN2 genes in the pasture group had significant levels of upregulation in the 7th month of lactation (3.538- and 5.436-fold, respectively), …

Thyroid hormones are known for their stimulation of feed efficiency and growth performance in different farm animals. More interestingly, the level of thyroid hormones is influenced by selection for growth in some animal species. Therefore, it was the aim of the current study to investigate whether a correlation exists between the blood triiodothyronine (T 3 ) level and some production traits (daily feed intake, average daily gain, and feed conversion ratio). To test this hypothesis, six male goat kids (21.9 ± 2.4 kg; 5 months old) belonging to Aardi, Damascus, and their cross breed (two kids from each genotype) were …
