Lambs fed 21% of PBSWD had higher (P < 0.05) back fat depth than lambs fed control diet.
Average backfat, 10th rib fat depth, longissimus muscle area and percentage lean also were not affected by feeding CMH.
However, sows in treatment L had a negative balance in back fat depth (mm) (L: −1.3, M: 0.5 H: 3.6; P<0.05) during the same period.
On d-84, pigs were weighed and scanned using real-time ultrasound to obtain fat depth and longissimus dorsi muscle (LM) area.
Live weight (+0.24±0.09 kg per year) and muscle depth (+0.05±0.02 mm per year) increased and fat depth (−0.03±0.02 mm per year) decreased under selection.
Responses, adjusted for animal size were greatest in fat depth (−0.90±0.63% per year) and least in muscle depth (+0.18±0.06% per year) with live weight being intermediate (+0.45±0.12% per year).
The aims of this experiment were to estimate genetic and phenotypic parameters, and responses in vivo for selection index component traits, i.e. live weight, fat depth and muscle depth.
Fat supplementation in the DP of the mature cows increased maximum back fat depth (from 3.6 to 4.5 mm), milk yield (low F = 26.3, high F = 28.7 kg/d), and Pr yields (low F = 837, high F = 899 g/d).
Dry period diet supplementation with F increased maximum back fat depth and milk and CP yields in the mature cows, and led to more LD muscle mobilization during early lactation.
The phenotypic data for both IMCL and SFD measurements were previously adjusted for year of birth, sex, age (days), live weight (kilograms), or fat depth (inches), as appropriate.
Thus, we hypothesized that genetic polymorphisms of UCN3 and CRHR2 genes are associated with intramyocellular lipid accumulation (IMCL) and subcutaneous fat depth (SFD) in mammals.
