This experiment was conducted to examine the effect of various legume herbs supplementation on feed intake, digestibility and liveweight gain of fat-tailed lambs given Mulato (Brachiaria mulato) grass. Twenty four male fat-tailed lambs (8 months of age and 12.73± 0.56 kg (SE) of initial liveweight) were randomly allotted to four treatment groups based on unfasted liveweight.  Animals were housed in individual metabolism crates. The experiment was designed in a completely randomized block design, with four treatments and six replicates. The dietary treatment tested included Mulato grass ad libitum (M), M + Centrosema pascuorum  (MCP), M + Dolichos lab lab (MDL) and M+ Clitoria ternatea (MCT). All supplement was offered at 1.5% body weight (W) per day.  The experiment lasted for 10 weeks, with 2 and 8 weeks for adaptation and measurement period, respectively. The main parameter measured included feed intake, feed digestibility, and average daily liveweight gain (ADG).  Results showed that total DM intakes (DMI) were not affected (P>0.05) by legume herbs supplementation. Total DMI was 2.75, 2.79, 2.84 and 2.87 %W/d for lamb treated with M MCP, MDL and MCT respectively. In contrast, supplementation with various legume herbs significantly increased (P <0.05) DM digestibility (DMD) and ADG of lamb received Mulato grass, with no significant difference (P>0.05) between legume herbs.  Feed DMD was 58.17, 67.48, 64.91; 65.03% and ADG were 35.67; 58.39; 54.31 and 54.41 g/day, for lamb treated with M, MCP, MDL and MCT respectively. It was concluded that supplementation of legume herbs to fat-tailed lamb fed Mulato grass significantly increased DMD and ADG, but no significant differences across the legume herbs as feed supplements were observed.

ABSTRACT   EFFECT OF UTILIZATION OF VIRGIN COCONUT OIL (VCO) IN THE DIET ON PIG PERFORMANCE. Utilization of fats and oils in pig diets is of great importance due to their high energy value. VCO is obtained by cold press processing of the kernel from the coconut fruit. Utilization of virgin coconut oil (VCO) in the diets on pig performance.  The present study was designed to elaborate the effect of utilization of VCO in the diets on energy and protein digestibility of growing pigs. The experiment was conducted using 20 castrated male pigs aged 1.5 - 2.0 months weighing 12,0±2,0 kg. The data were analyzed according to the linear model procedure for ANOVA appropriate for Randomized Block Design with 5 treatments and 4 replications. Treatments were formulated as follow: R0 = 100% control diet + 0% VCO; R1 = 99.5% control diet + 1.0% VCO; R2 = 98.0% control diet + 2.0% VCO; R3 = 97.0% control diet + 3.0% VCO; and R4 = 96.0% control diet + 4.0% VCO. Parameters measured were: daily feed intake, daily gain, daily water consumption. The results showed that the utilization of VCO up to 4% in the diets had no significant effect (P > 0.05) on daily feed intake, daily gain, daily water consumption of pigs. It can be concluded that the addition of VCO up to 4.0% in the diets has no significant meaning on pig performance.   Key words: Virgin coconut oil (VCO), Performance, Growing pigs

Background: The red-crowned crane (Grus japonensis) is one of the most vulnerable bird species in the world. Mycotoxins are toxic secondary metabolites produced by fungi and considered naturally unavoidable contaminants in animal feed. Our recent survey indicated that the mycotoxins had the potential to contaminate redcrowned crane’s regular diets in China. Objective: This experiment was conducted to investigate the protective effects of mycotoxin binder montmorillonite (Mont) on growth performance, serum biochemistry and oxidative stress parameters of the red-crowned crane. Methods: 16 red-crowned cranes were divided into four groups and fed one of the following diets; a selected diet, regular diet, or the selected diet or regular diet with 0.5% montmorillonite added to the diets. The cranes' parameters of performance, hematology, serum biochemistry and serum oxidative stress were measured. Results: Consuming regular diets decreased the average daily feed intake (ADFI), levels of haemoglobin (Hb), platelet count (PLT), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and catalase (CAT), but increased the activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatine kinase (CK) and lactate dehydrogenase (LDH). The supplementation of 0.5% Mont provided protection for the red-crowned crane in terms of feed intake, serum biochemistry and oxidative stress. Moreover, Mont supplementation had no adverse effect on the health of red-crowned crane. Conclusions: Taken together, these findings suggested that the addition of dietary Mont is effective in improving the health of red-crowned crane.
