This study examined the lipid content and short chain fatty acid composition of fleece samples collected from Cashmere goat (Capra hircus laniger) bucks at various times throughout the year. Fleece samples from does and gonadectomised goats were also analysed at one time during the breeding season for comparison. Lipid was extracted with chloroform/methanol azeotrope, saponified, and analysed for short chain fatty acids (C2-Clo) by gas chromatography and gas chromatography/mass spectrometry. Bucks had increased amounts of lipid and ethyl-branched fatty acids in fleece samples shorn from March to September, compared with fleece samples shorn in November and January. The increases in the amounts of lipid and ethyl-branched fatty acids corresponded with the breeding season and the period when the buck odour was increased. This supports the assumption that ethyl-branched fatty acids may be a pheromone in goats.

LTA regulates SCFA metabolism and improves intestinal mucosal immunity by improving cholesterol synthesis in the liver and inhibiting gluconeogenesis in the colon.

Cecropin A

We hypothesised that the dietary addition of the bioactive antimicrobial protein lactoferrin (LF) and peptides melittin (MT) or cecropin A (CR) at a dosage of 100 mg/kg to the diet of Wistar rats would result in strong modulatory effects on faecal microbial enzymatic activity, short-chain fatty acid and ammonia concentrations. To date, the changes in bacterial extracellular and intracellular enzymatic activities upon addition of dietary AMPs have not yet been studied. This experiment lasted 15 days; during the first 5 day period, the rats were fed the control diet (S) and diets supplemented with LF, MT or CR. On days 6–15, all rats were fed the control S diet. The faecal fermentation processes were substantially stopped after two days of treatment, on average, in all rats receiving LF and two AMPs. The deepest suppression effect was observed on the last day of treatment (day 5) and persisted through days 5–8. The highest decreases in faecal bacterial β-glucosidase and β-glucuronidase activities as well as in SCFA and ammonia concentrations were observed in the rats fed the CR diet. Only in the CR animals did the mechanism of suppressed microbial fermentation involve diminished enzyme release from bacterial cells to the digesta.
