  • The nutritive value of lentil straw (Lens culinaris) relative to 4% urea treated wheat straw (w/w) was assessed in adult bucks and milking buffaloes on-station and on-farm, respectively. A digestion-cum-nitrogen balance experiment was conducted with three bucks (24.35 kg) fed ad libitum lentil straw (LS), urea treated wheat straw (UTS) and a 1:1 (w/w DM basis) mixture of LS and UTS (LS:UTS) in a 3$\times$3 Latin square design. Though daily dry matter intake (g kg $W^{0.75}$ or % LW) of bucks fed LS and UTS did not differ significantly, that of LS:UTS was significantly (p<0.05) low. Similarly, digestibility of nutrients (DM, OM and CP) and nitrogen balance (g/day) did not differ significantly for bucks given LS or UTS although a significant positive improvement was evident in these parameters for LS:UTS. The digestibility of fibre fractions (NDF and ADF) was significantly (p<0.05) lower in LS as compared to UTS or LS:UTS. Except for the significantly (p<0.05) lower intake of DCP (g kg$W^{0.75}$), the bucks fed LS had statistically similar nutrient intake as compared to UTS. Feeding of LS:UTS resulted in significantly higher nutrient (DCP, TDN) intake by bucks. The important blood-biochemical parameters (haemoglobin,packed cell volume, glucose, urea nitrogen, total protein) and activity of serum enzymes (alanine aminotransferase and aspartate aminotransferase) did not differ significantly in goats irrespective of dietary treatment. In the onfarm study, eighteen multiparous milking buffaloes were randomly assigned into three equal groups to assess the relative effect of feeding untreated wheat straw (WS), UTS and LS:UTS ad libitum as basal feed with a supplement. The study continued for 3 months and revealed that daily dry matter intake and average milk production (liters/day) by buffaloes offered LS:UTS and UTS was statistically similar but it was significantly higher compare to WS. However, milk composition did not differ significantly among the dietary treatments. It may be concluded that the nutritive value of lentil straw appeared to be no different to UTS, however, a positive synergistic effect was evident by feeding a mixture of LS and UTS on performance of goats and lactating buffaloes.

  • The effects of Saccharomyces cerevisiae supplementation ($6.6{\times}10^8cfu$) and anhydrous ammonia treatment (3%) of wheat straw (WS) were investigated on in-situ dry matter (DM) degradability, and on rumen fermentation and growth performance of lambs. Rumen-fistulated Menemen sheep fed a diet with and without live yeast were used to assess the DM degradability characteristics of WS and ammonia-treated wheat straw ($WS_{NH3}$). Twenty-six yearling Menemen male lambs were fed in four groups. Lambs of control group (WS) received untreated WS without supplemental yeast, whereas other three groups were fed WS treated with anhydrous ammonia ($WS_{NH3}$ group), untreated WS and yeast (WS+YEAST group) or WS treated with anhydrous ammonia and yeast ($WS_{NH3}$+YEAST group). Supplemented live yeast (4 g/d) was added in the diet. Lambs were offered untreated or ammonia treated WS ad-libitum and concentrate was fed at 1% of live body weight. The degradability of the water-insoluble (fraction B) was significantly increased by all of the treatment groups. Potential degradability (A+B), effective DM degradability's (pe2, pe5, and pe8) and average daily weight gain increased only in $WS_{NH3}$+YEAST group (p<0.05). Voluntary DM intake was not increased by the treatments (p>0.05), but voluntary metabolizable energy and crude protein intake were increased by $WS_{NH3}$ and by $WS_{NH3}$+YEAST (p<0.05). Average daily rumen pH was not affected by any of the treatments, but average daily $NH_3$-N was significantly higher in the $WS_{NH3}$ and $WS_{NH3}$+YEAST groups, and total volatile fatty acids were significantly higher in the WS+YEAST and $WS_{NH3}$+YEAST groups. In conclusion, the improvement of feed value of WS was better by the combination of ammonia-treatment and yeast supplementation compared to either treatment alone.

  • Sixteen adult male buffaloes (average body weight $443{\pm}14kg$) were equally distributed into four groups in an experiment to study the effect of supplementary protein sources on energy utilization efficiency in buffaloes fed a wheat straw-based diet. The animals in the control group were offered a basal diet composed of 700 g deoiled ground nut cake and ad libitum wheat straw. Animals of other groups were offered 1.8 kg of soyabean meal (SBM), linseed meal (LSM) or mustard cake (MC) along with the basal diet. Protein supplementation increased the digestibility of DM (p<0.01), OM (p<0.01) CP (p<0.01) and CF (p<0.05). Maximum CP digestibility was observed on SBM, followed by LSM and MC when compared to the control. Total DMI and DOMI was significantly (p<0.01) higher in protein supplemented groups with no differences between treatment groups. Digestible crude protein (DCP) intake and N balance were significantly (p<0.01) different between the groups; maximum response was obtained with SBM supplementation, followed by LSM and MC. Faecal energy was significantly (p<0.01) lower in SBM and LSM groups in comparison to other groups. Methane production (% DEI) was significantly (p<0.05) lower on the SBM treatment. Metabolizable energy (ME) intake increased significantly due to protein supplementation. Metabolizable energy intake (MEI) of animals in the MC group was less than LSM and SBM. Energy balance was increased significantly (p<0.01) due to protein supplementation and within supplement variation was also significant with maximum balance in SBM followed by LSM and MC groups. Protein supplementation significantly (p<0.05) increased the digestibility and metabolizability of energy from whole ration. Metabolizable energy (ME) content (Mcal/kg DM) of SBM, LSM and MC was 4.49, 3.56 and 2.56, respectively. It was concluded that protein supplementation of wheat straw increased intake, digestibility and metabolizability of energy and maximum response could be obtained when soybean meal was used as a supplement.

  • Eight primiparous Holstein cows, in late lactation (255$\pm$10 days in milk) and yielding 10.3$\pm$1.3 kg/d of 4% fat corrected milk (FCM) were allocated into two groups randomly. Two diets containing 30% wheat straw either untreated (UWS) or treated with Pleurotus ostreatus (FTWS) were offered as total mixed ration (TMR). In vivo digestibility of the diets was determined, using acid insoluble ash as a marker. Daily milk production was recorded and milk samples were collected and analysed. Diet FTWS resulted in significantly (p<0.05) higher dry matter intake (DMI) (12.2$\pm$0.86 vs. 10.6$\pm$1.3), DM digestibility (58.8 vs. 52.3) and milk yield (9 vs. 7.5 kg). Milk fat contents were 34.2 and 35.6 g/liter that did not differ between cows fed treated or untreated straw. However, the concentrations of lactose, solid non fat, total solids and milk protein for diets UWS and FTWS were 57.3 and 54.9, 98.9 and 93.2, 134.5 and 127.4, 35.7 and 32.3 g/l, respectively, which differed significantly (p<0.05). The average body weights gain (BWG) for UWS and FTWS were 272 and 743 g/d, respectively (p<0.05). The FCM yield per kg of DMI was similar (0.68 and 0.67 liter) for the two groups, but BWG/kgDMI was higher in the FTWS diet.

  • Eight feeds and their residues left after washing with tap water (water residue) or incubation in the rumen (rumen residues) were treated with hydrochloric acid, neutral detergent solution without EDTA (NDS) or both, and the release or sorption of minerals (Ca, Mg, P, Na, K, Cu and Zn) assessed. Six of the feeds were from Sri Lanka (Panicum maximum ecotype Guinea A, Glyricidia maculate, Artocarpus heterophyllus (jak leaves), untreated and urea-treated rice straw, and rice bran) and two from the Netherlands (maize silage and wheat straw). The initial concentration of mineral elements, the concentration of neutral detergent fibre (NDF) and the type of feed significantly influenced (p<0.01). The proportion of the mineral elements released or sorbed. In general, feeds with high NDF content (straws and guinea grass) sorbed Ca from tap water, or released less in the rumen, and within these feeds the extent of sorption varied with source of fibre. Acid or NDS treatment removed little of the sorbed Ca, but they removed much of the Mg from both water and rumen residues. Fibres of wheat straw and jak leaves showed an affinity for Mg in the rumen. All feeds and their water and rumen residues sorbed P and Na from NDS, and the extent of sorption varied with the initial concentrations of these elements and with the type of fibre. Acid treatment removed part of the sorbed Na, but not the P. The solubility of K was not affected by the content of NDF, the type of fibre or the initial concentration of K. All feeds and their residues, except for the rumen residues of rice bran sorbed Cu from tap water and in the rumen. The recovery of Cu in rumen residues declined from 353% to 147% after NDS treatment, and with some feeds (glyricidia and jak leaves) the recovery was below 100%. Acid treatment removed part of the Zn sorbed by the water and rumen residues, but the capacity of residues to retain Zn varied with the type of feed.

  • The objective of the research was to investigate the effect of polyethylene glycol (PEG) or urea supplementation in sheep and goats fed a basal diet of Acacia saligna and wheat straw. The 3 dietary treatments were: (1) Control: ad libitum A. saligna+ 400 g/d wheat straw (95% DM) (basal diet); (2) Basal diet+50 g/d PEG 4000; and (3) Basal diet+1% (on a DM basis) urea sprayed onto the straw and A. saligna 30 min prior to feeding. All animals maintained live weight, regardless of the dietary treatment. All sheep readily consumed the A. saligna in preference to straw. In sheep both DMD and OMD were higher (p<0.05) where PEG was included in the diet compared to the other two treatments. Contrary to findings by other researchers there was no significant difference in DMI, DMD or OMD between sheep and goats in corresponding treatment groups. All animals were in positive N balance. For both sheep and goats, rumen ammonia concentrations were increased with the use of either urea or PEG. In these groups the maximum ammonia concentrations exceeded 50 mg/L, considered the minimum required to maximise microbial growth. This threshold, however, was exceeded only for a period of 8-11 h. Of those measured, rumen ammonia levels were generally the highest at 4 h post feeding. None of the measurements of rumen ammonia for the control group approached 50 mg/L. It is unclear how and why feed intake and live weight were maintained when rumen ammonia levels were often sub-optimal.

  • Forty-five Najdi ram lambs were equally and randomly allotted to five dietary groups with three replications per diet to evaluate the effect of feeding olive cake in complete diet on nutrient digestibility, growth performance and carcass characteristics. The diets were: a whole-mixed control diet (C) containing 12% wheat straw and four diets; namely O, ON, OU and OUE, where crude olive cake, 3% NaOH-treated olive cake, 5% urea-treated olive cake (U) and ensiled U, respectively were incorporated to replace the wheat straw of C diet. The results showed that the digestibility of DM, CP, EE and NFE and TDN were higher (p<0.05) in OUE diet as compared to the control diet; there were no changes (p>0.05) in the corresponding values between O, ON and OU diets. The nutrient digestibilities, body weight gain, feed efficiency and Longissimus area were significantly (p<0.05) lower in ON diet as compared to other experimental diets. Average daily DM intake and weight gain were higher (p<0.05) in lambs fed O, OU and OUE diets than those fed C diet. The moisture and protein contents in the soft tissue from ON treatment were lower (p<0.05) than those tissues from C, O, OU and OUE treatments. In conclusion, these results indicated that crude olive cake is a better substitute of wheat straw when fed to growing lambs.

  • Twelve cross bred cows ($300{\pm}20kg$) were fed a basal ration consisting of 1 kg concentrate and untreated or urea treated rice with or without urea-molasses-wheat bran lick block supplementation. The lick blocks were prepared locally using cement as a binding agent. The experiment lasted for 48 days consisting of a preliminary period of 14 days and a measurement period of 34 days. Daily dry ma tter intake (DMI) of straw and lick block, and daily milk yield were recorded during the measurement period. Intake of lick block when fed with untreated straw (US) was significantly higher (p < 0.01) than with urea treated (TS) straw (397 vs 307g $100kg^{-1}$), but lick block supplementation did not significantly affect the in take of US (1.80 vs 1.83kg $100kg^{-1}day^{-1}$) or TS (2.27 vs 2.17kg $100kg^{-1}day^{-1}$). Both urea treatment and lick block supplementation significantly increased (p < 0.01) the milk yield of cows, and the increase due to urea treatment was higher than that due to lick block supplementation. Benefit/cost ratio obtained for feeding US or TS with 1 kg dairy concentrate was similar (5.4), but the marginal return favours TS (5.4:1.0). The benefit/cost ratio for US and TS supplemented with lick block was 3.4 and 3.7. respectively, but the marginal return with US was higher than with TS (1.6:1.0 and 0.9:1.0, respectively).

  • 여러 가지 종류의 사료 섬유질이 수탉의 수분 Na 대사에 미치는 영향을 조사하고자 약 1년 된 SCWL 수탉 15수를 공시하였다. 시험사료는 5가지로서, 밀기울, 셀루로스 및 볏짚들로서 대조구의 옥수수를 10% 수준으로 대체하였으며, 펙틴은 8%수준으로 사용하였다. 각 시험사료 처리당 3수의 수탉을 사용하여 3반복으로 하였다. 시험사료의 건물 대사율은 셀루로스구와 볏짚구가 제일 낮았으며 (P$\leq$.05), 대조구와 펙틴구가 제일 높았다. 밀기울사료의 건물 대사율은 이들의 중간 정도이었다. 수탉의 음수량은 사료 g당 음수량으로 표시할 경우 펙틴구가 타 사료구들에 비해 유의하게 (P$\leq$.05) 높았으며, 배설물의 수분 함량도 제일 많았다. 그러나 이러한 음수량의 차이는 수탉을 결장척출수술을 하였을 경우 사라져서 처리구간에 유의한 차이가 없었다. 또한 음수량은 수탉을 수술하기 전보다 수술한 후에 유의하게 증가하였다. 배설물의 water holding capacity와 bulk density data는 셀루로스>볏짚>밀기울의 순으로 섬유질성이 강함을 보여 주었다. 결장척출수술을 한 탉의 혈장과 요의 $Na^{+}$ 농도와 osmolality는 사료처리구별로 유의성이 없었으며, $C_{Na+}$, $C_{osm}$$C_{H_2O}$에 있어서도 각 처리구 사이에 5 % 수준에서 유의성이 없었다. 그러나 요 배설량과 osmolality 및 $C_{H_2O}$의 수치들을 종합하여 볼 때, 공시한 15수의 수탉 중에서 11수가 다요증상을 보였으며, 섬유질성이 높은 사료를 섭취하는 수탉일수록 그 증세가 심하였음을 알 수 있었다. 결론적으로 본 시험에서 공시된 4가지의 섬유질들을 섬유질성이 높은 순으로 나열해 보면 펙틴, 셀루로스, 볏짚 그리고 밀기울의 순서라고 하겠다.하겠다.
