Effects of Parkia platycephala on feeding behavior, rumen health, blood markers, and physiological responses of lactating goats
ABSTRACT The objective of this study was to evaluate the effect of Parkia platycephala pod meal (PP) on feeding behavior, rumen health, blood markers, and physiological responses in lactating goats. Eight apparently healthy, adult, multiparous Anglo-Nubian goats, with an average body weight of 42.06±3.5 kg and approximately 52±4 days in lactation, were randomly assigned into two Latin squares (4×4) composed of four levels of PP (0, 33.3, 66.7, and 100% of dry matter) for four periods. Daily feed intake, feeding behavior, rumen health, blood markers (hemogram and biochemical parameters), and physiological responses (rectal temperature, respiratory rate, heart rate, and sweating rate) were assessed. Intake, feeding efficiency, and rumination efficiency were not affected by the replacement of ground corn with PP. At these replacement levels, the goats significantly spent more time feeding and ruminating. There was a significant decrease in the number of chews (number/day and number/min) with an increase in PP inclusion. Rectal temperature, respiratory rate, heart rate, and sweating rate were higher in the afternoon for the three periods measured. There were no negative changes in blood markers or rumen health with the use of PP. The current findings indicate that PP can be used to replace up to 100% of the corn in the diet of lactating goats without causing significant changes in animal health, feeding behavior, or physiological parameters.
