This study was conducted to investigate effects of leaves of mulberry tree (Morus alba) as a protein supplement to isonitrogenously replace rapeseed meal (RSM) on performance of growing lambs offered ammoniated rice straw (ABRS) (Trial 1), and to evaluate the digestive characteristics of the ABRS supplemented with different ratios of RSM and mulberry leaves in terms of in vitro gas production (Trial 2). In Trial 1, 45 Huzhou lambs were divided into

In vitro gas production was measured to investigate associative effects of untreated and chemically treated rice straw (RS) and of RS and grass hay or mulberry leaves (ML). The RS was treated with NaOH, urea, or (NH4)HCO3. Cumulative gas production was recorded at 2, 4, 6, 8, 12, 16, 24, 36, 48, 60, 72, and 96h of incubation, and the Gompertz function was used to describe the kinetics of gas production. Treatment with NaOH, urea, and NH4HCO3 increased (P<0.05) gas production at 48h by 55, 52, and 37% and the maximum rate of gas production of RS from 0.64 to 1.51, 1.27, and 1.13mL/h, respectively. The inclusion of treated straws, hay, and ML in a mixture with RS at increasing proportions (25, 50, 75, 100%) elevated cumulative gas production and its rate. Maximum gas production was not different between the RS and its mixtures with the treated straws, but inclusion of hayinto RS or NH4HCO3-treated RS increased the maxi-mum gas production. Associative effects were defined as the difference between the observed gas production for the mixtures and the sum of the individual component feeds. The NaOH-treated RS, included at higher proportions, had positive associative effects at all times of incubation <96h; effects were negative or absent at 96h. No effects were observed with mixtures of RS with urea-treated RS. The NH4HCO3-treated RS mixture tended to have negative associative effects at all three levels. Positive associative effects (P<0.05) were observed for both RS and NH4HCO3-treated RS at almost all inclusion levels of hay or ML after 12 to 96 h of incubation. The response was more pronounced with ML than with hay. Associative effects generally declined with duration of incubation. We conclude that positive associative effects on in vitro gas production occurred more consistently when RS was incubated in mixtures with hay or ML than when incubated in mixtures with chemically treated RS.

A series of nitrogen (N) balance trials were carried out to investigate the requirement of crude protein (CP) for maintenance in Shaoxing Ducks. The N balance was determined for five periods from the age of 1 day to 28 weeks (0-4 weeks, 5-8 weeks, 9-16 weeks, 17-20 weeks, 20-28 weeks). Fifteen ducks were used in each period. The birds were divided into three equal groups and fed on the diets with equal metabolizable energy (ME) and different contents of CP (low, medium and high). The N requirements for maintenance were estimated from the relationship between the N retention and N intake (NI). Following the above series of N balance test, 25 ducks at the age of 10 weeks were used in an N balance test with N-free ration. The birds were divided into five groups and offered N-free ration at levels of 100, 75, 50, 25 and 0g per day, respectively. The net protein utilization (NPU) ranged from 0.45 to 0.53 and increased with the advancing age of ducks, but no significant difference was found among different contents of the dietary CP. The estimated N requirement for maintenance was, on an average, 455mg/kg BW0.75 per day, which was equal to 2.8g CP/kg BW0.75 per day. The result from the trial in the Nfree ration showed that the value of N requirement for maintenance was 467mg/kg BW0.75 per day, conforming the results in the series of N balance test. The lower intake of N-free ration resulted in more N excretion suggesting that protein catabolism may occur in the body of birds to meet maintenance requirements forNwhen the dietary NI was very low.

This study investigated the quality of bamboo shoot shell silage prepared with or without rice straw (RS) or/and wheat bran (WB), and to evaluate their nutritive value in terms of chemical composition, ruminal degradation characteristics, and voluntary intake by lambs. The bamboo shoot shells silages were prepared in experimental silos to create four treatments: (1) 100% (fresh basis) bamboo shoot shells (control); (2) 90% bamboo shoot shells+10% RS (RS10); (3) 90% bamboo shoot shells+5% RS and 5% WB (RS5WB5), and (4) 90% bamboo shoot shells+10% WB (WB 10). Voluntary intakes of the silages were determined in a 4

This study was conducted to evaluate the cellulase treatment of the untreated (URS) and steam pre-treated rice straw (STRS) in terms of dry matter loss, sugar composition and in vitro gas production (GP). The STRS was prepared at 15 bar for 5min with a water-to-straw ratio of 30:70 (w/w). Enzymic hydrolysis of straws was accomplished in a 378C incubator. Wet samples of the URS and STRS were sacchari

The objective of the present study was to study the effects of different conditions of steam treatment on nutritional value of rice straw (RS). The steam treatment was accomplished in a high pressure vessel at pressures 15, 17 and 19kg/cm2 for a range of treatment time (0, 5 and 10min) at a water-to-straw ratio of 1:1. The effect was also studied of the amount of water added (0:100

Thirty-two Holstein heifers were allocated to four groups and used to investigate the response in growth rate to supplementing ammonia bicarbonate-treated rice straw (ABRS) with Chinese milk vetch (Astragalus sinicus L.) silage (MVS). All groups were offered ABRS ad libitum with 1 kg of a concentrate mixture per head per day, and the MVS was supplemented at levels of 0, 10, 20 or 30% of the calculated dietary dry matter intake. Intake of ABRS was not affected by a 10% inclusion rate of MVS but inclusion at each of the higher levels reduced ABRS intake. Dry matter intakes were higher in all three supplemented groups, and daily liveweight gains were 588g, 692g, 800g and 777 g in the groups supplemented with MVS at levels of 0%, 10%, 20% and 30%, respectively. When MVS accounted for 20 or 30% of the diet, the liveweight gains were significantly higher than in the non-MVS group (P<0.05). Concentrate consumption per kilogram liveweight gain was 1.70kg, 1.45kg, 1.25kg and 1.30kg for the 0%, 10%, 20% and 30% levels, respectively. It is concluded that supplementation of an ABRS-based diet with MVS may improve the growth rate of ruminants and save concentrate consumption. The results of orthogonal contrasts indicate that the optimal level of supplementary MVS in this study was 23% of the dietary dry matter intake.

Three sheep were used to study the effects of ammonia bicarbonate (AB) treatment on ruminal fiber digestion kinetics, nutrient digestibility and nitrogen (N) utilization of rice straw (RS). The results for RS and AB-treated RS (ABRS) were compared with those for hay which is commonly used in our region. The AB treatment significantly increased dry matter intake and nutrient digestibility of RS (P<0.05). The digestibility of nutrients of ABRS were higher than those of hay. Nitrogen retention was highest in animals fed ABRS (P<0.05), followed by hay and the lowest in RS. The AB treatment had little effect on the potential degradability of protein in the rumen, but the degradation rate of the slowly degraded fraction was greatly increased by treatment with AB. Effective protein degradability was 64.4%, 48.7% and 46.2% for ABRS, hay and RS, respectively. Higher N content and rumen degradation in ABRS resulted in a more synchronized supply of nutrients to the rumen microbes than in RS and hay. The RS and hay had similar potential extent of digestion (PED) and a similar rate ofPED (kd) of fibrous materials. The RS had a shorter discrete lag time of digestion than hay. The AB significantly increased the PED (P<0.05), kd (P<0.01) and rate of ruminal passage of digesta of RS, but had little effect on lag time. These results indicate that treatment of RS with AB can increase N content, improve ruminal fiber digestion and protein status in lambs, and in turn increase the intake and digestibility, suggesting that AB can be utilized as an effective source of ammonia for upgrading RS.
