“…Moreover, the Chinese herbal medicine might also produce impact to enhance plasma glucose kinetics due to its bioactive properties on hematopoiesis. Previous findings (Al‐Mamun, Sako, & Sano, ; Sano et al., ) reported an increased plasma GluTR in sheep during the cold exposure period, which is in accordance with our present result. When the animals are exposed to cold, the oxidation of nutritive substances in the body should increase to meet the increased heat requirement.…”

An experiment was carried out to assess the feeding effect of Chinese herbal medicine on N balance, ruminal fermentation characteristics, kinetics of plasma glucose, leucine and energy metabolism in sheep kept at thermoneutral environment (23°C) or exposed to cold (2-4°C). Four sheep were subjected to either mixed hay (MH-diet) or hay supplemented with 2% of a traditional nourishing Chinese herbal medicine mixture (Astragalus root, Angelica root and Atractylodes rhizome; CHM-diet) over two 23-day periods using a crossover design. Cold exposure was conducted for 5 days. The isotope dilution of [U- C]glucose with open circuit calorimetry was used to determine the turnover and oxidation rates of plasma glucose and metabolic heat production. The rate of plasma leucine turnover was measured with an isotope dilution method using [1- C]leucine. N intake was higher, N excretion through faeces was lower and N digestibility was higher for the CHM-diet than the MH-diet. Rumen pH was lower, concentration of rumen NH was higher, concentrations of rumen total VFA and acetate tended to be higher and propionate was higher for the CHM-diet compared with the MH-diet. Turnover rate of plasma glucose was higher for the CHM-diet than the MH-diet and increased during cold exposure. Oxidation rate of plasma glucose did not differ between diets and also between environments. Turnover rate of plasma leucine was higher for the CHM-diet compared with the MH-diet but remained similar between environments. Heat production was greater for the CHM-diet than the MH-diet and increased during cold exposure. No significant diet × environment interaction was detected. The present results demonstrated that plasma glucose and energy metabolism were enhanced by both Chinese herbal medicine and cold exposure; plasma leucine metabolism was enhanced by Chinese herbal medicine but with lack of change in response to cold exposure in sheep under the conditions of the current experiment.

“…With its assumed low tannin content [66], the 100% MSM diet would have protected these amino acids from ruminal microbial degradation [98]. Indeed, an increase in glucose concentration may be due to more by-pass protein and increased availability of glucogenic amino acids for glucose synthesis [99]. Increased post-ruminal flow of glucogenic amino acids and lipogenic moieties results in improved muscle mass accretion [100].…”

23The productivity of indigenous goats in Africa is constrained by shortage of protein-24 rich feed especially in winter. This study investigated the nutritional value of mucuna 25 forage (MF) and seed meal (MSM) as alternative protein sources for indigenous 26 goats. Mucuna was planted in 3 parallel and adjacent fields and its foliage nutritional 27 composition determined at 4, 8, 12 and 16 weeks after planting (WAP). MF was 28 harvested at 14 WAP whilst mucuna pods were harvested at 28 -30 WAP, shelled 29 and the MSM chemically analysed. In a completely randomised design (CRD), 20 30 indigenous goats were randomly offered 5 treatment diets with, respectively, 0%, 31 25%, 50% and 100% MF and 100% MSM replacing broiler litter (BL), each with 4 32 replicates, for 82 days. Both mucuna foliage DM and CF contents increased (P < 33 0.001) whilst foliage CP, EE and ash contents decreased (P<0.001) with maturity. 34On the other hand, MSM contained high DM (90.7%), EE (3.7% DM) and CP (26.0% 35 DM) but low CF (9.7% DM) and ash (5.5% DM) contents. Both body weight gain 36 (BWG) and feed conversion efficiency (FCE) were not influenced by dietary mucuna 37 incorporation (P > 0.05). However, dietary MF, particularly at the 100% level, 38 decreased goat feed intake (FI) (P < 0.001) whilst 100% MSM increased (P < 0.001) 39 this parameter. Mucuna had no effect on all carcass characteristics (P > 0.05) but 40 increased (P < 0.05), particularly at the 100% MSM level, hot carcass weight and 41 dressing percentage. There were no effects of mucuna on all biochemical and 42 haematological indices (P > 0.05), except for the increase in serum glucose (P < 43 0.05). In conclusion, the optimal stage for harvesting and utilisation of MF is between 44 12 and 16 WAP and both MF and MSM, particularly the latter, are rich alternative 45 protein sources for indigenous goats. 46 3 47 Keywords: Mucuna pruriens forage and seed meal, nutritional composition, 48 performance, biochemical and physiological indices, indigenous goats.49 50 Introduction 51 The world goat population is ~921 million, >90% of which are found in developing 52 countries [1]. Of these, ~352 million goats are in Africa [2], >90% of which are owned 53 by smallholder farmers [3]. The major concentration of goats in Africa is in the sub-54 Saharan region with 60% of the total goat population representing ~80 indigenous 55 breeds raised under various production systems [3]. Indigenous goats (Capra hircus) 56 play important roles mainly in terms of food and nutrition security, poverty alleviation, 57 and cultural life of smallholder rural-based farmers and societies in Africa [4, 5, 6]. 58They provide immediate benefits in the form of meat, milk, leather, cash income, 59 manure and other miscellaneous products to the poor in communal areas [5, 7] and 60 also play a pivotal role in traditional ceremonies [6, 8]. They generally have small to 61 medium frame with short horns and a variety of coat colours [4, 9]. Unlike the Boer 62 and dairy goats, indigenous goats remain rather un...

“…Similar results [26] noticed that there was an increasing in concentration of blood glucose due to more glucogenic amino acids available for gluconeogenesis, when the protein from leguminouse leaves was added in the diet. An increasing in glucose concentration occured due to more by-pass protein and increased availability of glucogenic amino acids for glucose synthesis [27]. When sheep fed Gliricidia sepium as protein sources feed was increased [28].…”

The limiting factor on improving ruminant production for most of the available feed in developing countries are low in quality. Therefore high fibre diet must be supplemented by high nutritive feed such as leguminous trees that much available in those regions. Gliricidia sepium was one of very potential candidates. Glucose as a major energy source in fed animals required precursor in form of propionat and amino acids from diet. Those precursors might be supplied by these legume leaves. The aim of this research was to investigate the glucose metabolism in the sheep fed grass supplemented by Gliricidia sepium. Fifteen sheeps (18 months old) were used in the experiment. These are were divided into three groups that fed by experimental diet of Mitchell grass (MG group), Gliricidia (GS group), and MG supplemented with GS (MGGS group). D-[U-14 C]glucose infusate was infused continuously through the left jugular venous catheter of each animal to measure glucose metabolism in those sheeps. The measurements were done on feed utilisation and glucose metabolism. The results indicated that there was an improvement in efficiency of feed utilisation in the MGGS group as reflected by lower feed conversion ratio by the group. Plasma glucose concentration profile per unit of OM intake were similar for GS and MGGS groups, but higher than that in the MG group (P<0.01). Glucose entry rate (GER) increased in MG group through GS to the MGGS group, while N retention accordingly was increased. It can be concluded that the utilization of GS by the ruminant animal could be improved by feeding it with a low quality feed at a ratio of 40:60 (GS:Low quality feed) to achieve an NI:DOMI ratio of 0.03 -0.04. This improvement would be manifested in increasing DOMI, with subsequent increase in GER or net protein deposition as might be expressed in positive N retention.
