Abstract

To estimate physiological changes due to added fat in bovine diet, whole cottonseed (19% lipids) was furnished to half-breed zebu cattle during 7 months. Thirty animals had increased its dietary lipidic charge in 2.6% (lot S), thirty were used as controls (lot C) and other two bovines were hyper-dosed with 7.9% added fat (lot H). Weight, clinical signs and plasmatic values of total cholesterol (TC), triglycerides (TG), lipoproteins (LP) and other biochemical parameters were monthly controlled. At the end of the assay the steers were sacrificed and the quality of meat and fat was evaluated. The initial levels of TC were statistically homogeneous in all groups (mean = 1.0 g/l); they remained without modifications in C (1.53 g/l), but they had increased progressively in supplemented animals. At the end of the work TC was greater in H (3.95 g/l) than in S (2.44 g/l). Latest TG (initial mean = 0.30 g/l) also were greater in H (0.74 g/l) than in S (0.71 g/l). The lipoproteinogram stayed inalterable in C, meanwhile alpha LP were increased and beta LP were decreased in animals on which the dietary lipidic charge had been increased. The weight's gain/animal/day (X) was 130 g (C), 290 g (S) and 88 g (H). The general physiological conditi...Continue Reading

ApoE, Lipids & Cholesterol

Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases. Here is the latest research.
