  • The effect of feeding concentrate mixture devoid of grain on the performance of crossbred dairy cows was studied. Twelve crossbred cows of first/second lactation were randomly distributed into two equal groups. The animals of group 1 were fed on a concentrate mixture containing 30% maize grain whereas, the cows of group 2 were offered a concentrate mixture where grain was completely replaced with deoiled rice bran (DORB) and molasses. Wheat straw was given ad libitum to the cows of both the groups. The feeding was continued for 112 days. The intake of dry matter, CP and TDN were similar in both the groups. Digestibility of DM, OM, EE, NDF and ADF were also comparable between the groups. The average daily fat corrected milk (FCM) yield was 7.70 kg and 7.43 kg in group 1 and 2, respectively. The chemical composition of milk (protein, fat and total solids) also remained unaffected. The animals of both the groups gained 9-10 kg body weight which indicates that both the diets were nutritionally adequate and grain can be successfully replaced with DORB and molasses from the diet to sustain about 6-7 kg FCM production.

  • The experiment was conducted to determine the effect of different fiber levels on milk production of crossbred Holstein milking cows fed urea-treated rice straw (UTS) as a roughage. Eight cows were allotted into 2 squares of 4 cows each with 4 treatments by a balanced design. The treatments were 17%, 22%, and 24% crude fiber (CF) diets and Thai feeding system (free choice of roughage and 1 kg of concentrates/2 kg of milk) as a control. Body weight change was not significantly different among the treatments during the experiment. Milk production (4% FCM) and milk protein content wee not different among the treatments, but milk fat content was low in the 17% CF group and high in the control group. Cows fed the 17% CF diet consumed less UTS and more concentrates than the others, and consequently total DM intake was not different among the treatments. The feed conversion ratio was significantly higher in the control. Feed cost per kg milk was lowest in the control and highest in the 17% CF diet. The fiber content of the diet would be more than 17%, preferably 22-24% for normally producing Thai crossbred Holstein cows when the UTS was fed as a main roughage source.

  • Early weaning is a means of breaking the disease cycle from sow to piglet as well as capitalising on the enormous growth potential of the pig. However, the transition from milk to dry diets results in a growth check. Feeding of supplemental milk, fermented to reduce pH and enterotoxigenic bactetial proliferation, may be a means of gradually weaning pigs on to solid feed. This study involved 216 pigs weaned from the sow at 12 days of age, allocated to groups of 6 males and 6 females per weaner pen and allowed ad libitum access to a pelleted diet. In addition, half the pigs were given supplemental fermented skim milk for the first 8 days after weaning. Feeding supplemental fermented milk increased feed intake (104 vs. 157 g DM/d, p=0.011), average daily gain (-3 vs. 112 g/d, p<0.001) and feed conversion efficiency (0.01 vs. 0.81, p=0.003) over the first 8 days after weaning. The improvements observed in the supplemented pigs continued to be augmented such that, by 42 days of age, the pigs that had received supplemental fermented milk were heavier (9.6 vs. 11.5 kg, p=0.003) than their unsupplemented counterparts. Feeding fermented supplemental milk to early-weaned pigs can improve growth performance in the immediate and subsequent post-weaning period.

  • An experiment was conducted for 56 days using nine castrated male Black Bengal goats (initial live weight 9.0 kg) aged about 5 months to study the effects of feeding Sesbania leaves as a sole feed on growth performance and nutrient utilization. The animals were fed ad libitum on either road-side grass, Sesbania aculeata leaves or Sesbania rostrata leaves. Average dry matter (DM) intake was 179, 229 and 259 g/d for goats fed road-side grass, Sesbania aculeata and Sesbania rostrata, respectively. Corresponding mean values for average daily live weight change were -6.6, 9.5 and 38.1 g, respectively. These values were higher (p<0.05) for goats fed Sesbania leaves than those given road-side grass. The apparent digestibility of all the proximate components except CF and the concentrations of DCP, TDN, DOM and ME of Sesbania leaves were higher (p<0.05) than those of road-side grass. Sesbania rostrata was superior (p<0.05) to Sesbania aculeata for nutrient digestibilities (except for NFE) and also for DOM, DCP and ME concentrations. Therefore, it may be concluded that the production of Sesbania rostrata, a legume fodder, should be encouraged for feeding goats.

  • In order to investigate the effects of dietary cellulose and protein levels on chick performance, four semi-purified diets were formulated so as to contain cellulose at levels of 5% (LC) and 20% (HC) in combination with 10% (LP) and 20% (HP) protein, and fed ad libitum to 1-week-old White Leghorn male chicks for 3 weeks. There were no significant differences in feed intake, body weight gain and feed efficiency between the LC-HP and HC-HP groups. All parameters were lower in the LP groups; the HC-LP group consumed very small amount of feed and lost body weight during the experiment. The retention rates of DM, ash, nitrogen and energy were higher in the HP than the LP groups. The triglyceride concentration of carcass was lower in the HC-LP group and that of liver was higher in the LC-LP group. The carcass total cholesterol level was higher in the HC-HP group. The relative weight of most digestive organs was higher in the HP group irrespective of the cellulose level. In conclusion, the chick performance was primarily influenced by dietary protein level, and when the chicks were fed inadequate levels of protein, the low cellulose level gave a better performance than the high cellulose level.

  • A nutrition study on weaned pigs using fermented soybean meal was done to determine the effect on growth performance, nutrients digestibility, blood profile and fecal microflora. A total of 100 weaning pigs with an initial average body weight (BW) of 8.27 ± 1.10 kg were randomly allotted into 1 of 2 dietary treatments in a 6-week feeding trial. There were 10 replicate pens in each treatment with 5 pigs per pen. The dietary treatments included: 1) control: Basal diet (CON); 2) fermented soybean meal (FSBM): Basal diet supplemented with 5% fermented soybean meal. The average daily feed intake (ADFI) was significantly improved (p < 0.05) with the dietary supplementation of the FSBM compared with the control meal during phase 2. The dietary supplementation with 5% FSBM had a significant effect (p < 0.05) on gain to feed ratio (G : F) during the overall experiment period. Collectively, the results of this study indicate that dietary supplementation of 5% fermented soybean meal improved the body weight and average daily gain (ADG), ADFI, and feed efficiency of the weaning pigs; however, there were no supplementation effects on total tract digestibility of dry matter (DM), nitrogen, energy, blood profile and fecal microflora.

  • The frequency of obesity has risen dramatically in recent years but only few safe and effective drugs are currently available. In addition, obesity can induce type 2 diabetes (T2DM), hyperlipidemia and fatty liver disease. Recently, protective effect of purslane extract (PE) on obesity has been reported, but little is known about the role and mechanism of PE in obesity. This study aimed to evaluate the effect of PE on obesity and diabetes in obese mice. In addition, the effect of PE was compared with anti-obesity and diabetes drugs. High-fat diet (HFD)-induced obese mice were treated for 8 weeks with drugs as follows: PE, orlistat, metformin, voglibose or pioglitazone. While PE mixed with normal diet did not have any effects on BW in non-obese mice, PE mixed with HFD significantly reduced BW gain, insulin resistance, and glucose intolerance, without affecting food intake and appetite in obese mice. The effect was comparable to the effects of anti-obesity and diabetes drugs. Furthermore, PE significantly increased the activity of hepatocellular anti-oxidant enzymes, leading to protection of liver from oxidative stress in obese mice. These results suggest that PE treatment may be a useful tool for preventing obesity and complication of obesity.

  • Dietary levels of fermented poultry manure(FPM) 0%, 5%, 10% and 20% were included in experimental diets. It is to examine the effects of diets containing different levels of FPM on the performance of broiler chicks, including the nutrient availabilities, compared with that of the commercial diet. In order to evaluate the nutritive value of FPM, feeding and metabolism trials were conducted with a total of 160 broiler chicks for a period of 4 weeks. Contents of CP, crude fat, crude ash, crude fiber and NFE of FPM were 19.43, 2.43, 15.44, 16.57 and 38.31 %, respectively. Although there were no statistical difference in the body weight gain among treatments, weight gain achieved by the group fed diets of 5% substitution of FPM was slightly better than others. The amount of feed intake was significantly higher for FPM included groups than for control group, especially in the group fed diets of 10% substitution of FPM. The feed efficiency tended to be better for the control group than the FPM groups. The feed efficiency tended to get worse as the levels of FPM increased. The digestibility of DM, CP and NFE tended to be similar among treatments, especially it was lower for the group fed diets of 20% substitution of FPM compared with that of another groups. In conclusion, up to 10% substitution of FPM to the diet can be utilized effectively as a broiler feed ingredient, without adversely affecting growth performance.

  • Four, mature rumen fistulated male swamp buffaloes with an average initial weight of $426{\pm}25kg$ were randomly allocated to receive dietary treatments according to a $4{\times}4$Latin square design. Four dietary treatments with varying proportions of ureatreated rice straw (UTRS) and cassava hay (CH) were offered (100:0, 75:25, 50:50, 0:100). Each feeding period lasted 21 days, the first 14 days for feed adjustment and intake measurement and the final 7 days for rumen fluid and faecal collections. The results demonstrated the potential use of both UTRS and CH as roughage sources. As levels of CH increased in the diets pH values were maintained (6.5-7.0). Ruminal $NH_3-N$ concentrations were significantly (p<0.05) raised as higher levels of CH were incorporated into the diets. Moreover, cellulolytic and proteolytic bacterial populations were enhanced while total protozoal counts were decreased (p<0.05). In addition, DM, OM and CP digestibilities and their digestible intakes as well as estimated energy increased with increasing levels of CH in the diets. The results suggest a favorable effect of CH substituting for UTRS.

  • An experiment was conducted to study the performance and carcass characteristics of Hanwoo steers fed whole crop corn silage ensiled with poultry manure (PM) for 18 months. The experiment was designed as a randomized block design with three phases. Steers were allotted in one of three dietary treatments, which were ammonia-treated rice straw (AS), whole crop corn silage (CS) and whole crop corn+30% PM silage (based on DM; MS). All diets were supplemented with concentrate. Total body weight gain and average daily gain (ADG) in MS group were increased (p<0.05) by 6% over AS group. The MS treatment enhanced (p<0.05) total and daily intakes of forage compared with the AS and CS treatments while there was compensatory effect on concentrate intake by AS group. Carcass characteristics were improved by feeding MS. MS increased (p<0.05) carcass weight and marbling score (7.5 and 22.5% of AS, respectively), and reduced (p<0.05) backfat thickness (13.2 of AS and 16.6% CS). Carcass grade and meat quality grade were also improved by MS compared with AS and CS. Under the conditions of this study, MS was an efficacious replacement for corn silage for steers.
