Serum glucose (GLU), total cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), and phospholipid (PL) were measured using commercially available kits (Nanjing Jiancheng Bioengineering Institute, Nanjing, China) and an automatic biochemical instrument (Biochemical Analytical Instrument, Beckman CX4; Beckman Coulter Inc., Brea, CA, USA), and the content of very low density lipoprotein (VLDL) was calculated based on the levels of TC, HDL and LDL (VLDL = TC−HDL−LDL). Furthermore, Serum insulin, glucagon, and leptin levels were assayed using commercially available ELISA kits (Beijing Chenglin Biotechnology Co., Ltd., Beijing, China) and an automatic biochemical instrument (Biochemical Analytical Instrument, Beckman CX4; Beckman Coulter Inc., USA). All measurements were conducted in triplicate at minimum according to the manufacturer’s instructions.

Serum biochemical parameters, including total protein (TP), albumin (ALB), alkaline phosphatase (ALP), alanine transaminase (ALT), aspartate aminotransferase (AST), blood urea nitrogen (BUN), glucose (GLU), and lactic dehydrogenase (LDH), were measured using Biochemical Analytical Instrument (Beckman CX4) and commercial kits (Sino-German Beijing Leadman Biotech Ltd, Beijing, China).
Serum samples were treated with sulfosalicylic acid, centrifuged, and filtered through a 0.45 μm filtration membrane. Then the amino acid concentrations were determined using an automatic amino acid analyzer (Model L-8900, Hitachi Ltd. Tokyo, Japan).
The serum concentrations of cholecystokinin (CCK), peptide YY (PYY), ghrelin, glucagon, and leptin were determined using the corresponding pig ELISA Kit (CUSABIO, Wuhan, China) in accordance with the manufacturer's instructions.

After overnight fasting, blood was collected via the jugular vein at 6 am on weeks 0, 4, and 8. Blood samples obtained from each goat were placed into a vacuette tube with lithium heparin (Greiner Bio-One GmbH, Kremsmünster, Austria) and then centrifuged at 3500× g for 5 min at 4 °C to collect serum, which was stored at −80 °C for further analysis. The levels of blood urea nitrogen (BUN), total cholesterol (TC), total triglyceride (TAG), and total protein (TP) were determined using a Biochemical Analytical Instrument (Beckman CX4). The following growth hormone (GH) and SIF commercial ELISA kits were used for hormone determination according to the manufacturer’s instructions: growth hormone (MB-4795A, Jiangsu Meibiao Biotechnology Co., Ltd., Nanjing, China) and SIFs (FT-P9S1826X, Jiangsu Meibiao Biotechnology Co., Ltd., Nanjing, China). All analyses were conducted on the same day and included a standard curve.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
