Growth Performance, Carcass Characteristics and Meat Yield of Boer Goats Fed Diets Containing Leaves or Whole Parts of <italic>Andrographis paniculata</italic>

Abstract

The study was conducted to determine the effect of feeding diets containing Andrographis paniculata leaves (APL), whole Andrographis paniculata plant (APWP) and a control without Andrographis paniculata (AP0), on growth performance, carcass characteristics and meat yield of 24 intact Boer bucks. The results obtained indicated that inclusion of Andrographis paniculata significantly improved feed intake, weight gain, feed efficiency and live weight. The ratios of carcass to fat, lean to bone, lean to fat, and composition of meat were also improved. In addition, there were significant differences (p<0.05) between the dietary treatments in dressing percentage and chilling loss. Goats fed on AP0 (control) had significantly higher proportions of fat and bone, as well as thicker back fat than the supplemented animals (APL and APWP). Higher gut fill in animals fed Andrographis paniculata suggested slow rate of digestion, which could have improved utilization and absorption of nutrients by the animals. Goats fed Andrographis paniculata also produced higher meat yield and relatively lower fat contents (p<0.05).

Effects of rations containing formaldehyde-protected soybean meal on meat production in Kacang goats

“…[38] (44.7-47.6%), Yusuf et al . [35] (40.3-48.1%), and Akbaş and Saatci [39] (43.9-46.1%), while they were higher than those reported by Sumardianto et al . [40] (40.9%) and Adiwinarti et al .…”

“…In addition, Yusuf et al . [35] reported that a heavier carcass was due to higher feed intake and better weight gain. Kacang goats are a local Indonesian goat that has a small body size (Kacang means that the goat is as small as a peanut); therefore, the carcass weight is also low.…”

Effects of dietary supplementation of leaves and whole plant of Andrographis paniculata on rumen fermentation, fatty acid composition and microbiota in goats

“…Andrographis paniculata (AP), called ‘king of bitters’ is a medicinal plant that is native to Asia [ 7 ]. The PSMs in different parts of AP [ 7 – 9 ] and the effects of AP on in vitro rumen metabolism [ 9 ] and growth performance in goats [ 10 ] have been documented. However, information regarding the effects of AP on in vivo rumen metabolism and nutrient digestibility in ruminants is very scarce.…”

“…Results of other studies showed that the loin eye area on lamb varied from 4.22-7.69 cm 2 (Duldjaman, 2005). Wider variation was reported by Yusuf et al (2014) from 4.79±0.10 to 9.08±0.64 cm 2 . The results of Brady et al (2003) research showed that the loin eye area ranged from 11.61-25.60 cm 2 , this variation was due to the differences in breed and final body weight.…”
