AbstractEighteen 4-month-old lambs, with a mean live weight (LW) of 19.47 ± 0.20 kg, were used to evaluate the nutritive value of date palm leaves (DPL) ensiled with different additives in a completely randomized design. Lambs were stratified into three groups of 6 lambs each and fed a control diet comprising 60% concentrate feed mixture (CFM) and 40% DPL silage (T1). In other treatments, the DPL silage (DPLS) of the control treatment was replaced with EM1 additive-treated DPLS (T2) or El-Mofeed additive-treated DPLS (T3). Apparent digestibility, total digestible nutrient, digestible crude protein, dry matter intake, daily weight gain (DWG), price of DWG, daily profit, and economics of feed efficiency were higher (P < 0.05) for the additives-treated DPLS relative to the control, with T2 enhancing these parameters compared with T3. With exception of ruminal pH, which was reduced, concentrations of ruminal NH3-N and total volatile fatty acids (VFA) increased 4 h post feeding. However, ruminal NH3-N and total VFA were greater (P < 0.05) for the additives-treated DPLS, with T2 producing higher values than T3. Ruminal pH and feed cost/kg LW gain were lower for T2 relative to other treatments. Blood constituents were within the normal ranges for lambs, though slightly altered by treatments. Whereas serum total protein, albumin, and globulin were affected (P < 0.05) in this rank order, T1 < T3 < T2, other serum parameters were not affected. Relative feed cost and relative daily profit were lower and higher respectively for T2 than for T3. It is concluded that additives-treated DPLS is nutritionally superior to untreated DPLS as a roughage source in total mixed rations fed to growing lambs. However, for improved performance of the lambs and economic benefits, EM1-treated DPLS is recommended.

A 4 week experiment involving 45 growing albino rats was carried out to assess the nutritional utilization of cooked full-fat soybean (CFFS) as a major source of dietary protein relative to that of the protein concentrates fishmeal-groundnut cake mixture and the response to supplementation of the cooked soybeans with 2g DL-methionine/kg diet and/or 2g L-lysine/kg diet. Feed intake (FI), average daily weight gain (DLG),. feed conversion ratio (FCR), protein efficiency ratio (PER) and feed cost (FC) per unit live-weight gain, (FC/WG) were measured, No significant effect of the various dietary treatments was observed on PER and FCIWG. However, the incorporation of CFFS either alone or in conjunction with either of both lysine and methionine significantly improved Fl and FCR (P< 0.05) and also DLG (P< 0.01) over the control fish-groundnut meal ration. Supplementation of CFFS with lysine either alone or along with methionine appeared unwarranted as methionine supplementation alone resulted in similar or slightly better efficiency of protein (0.247) and overall feed (0.596) utilization. From the results obtained, it appears that maize-based CFFS diet supplemented with 2 g/kg DL-methionine may be applicable for lion- ruminant feeding. However, since this level of methionine supplementation only provides for 67% of rat requirement, it is suggested that further studies with higher methionine levels be conducted.

A 42-day feeding trial was conducted to investigate the performance characteristics and cost benefit of feeding weaner rabbits cashew nut residue (CNR) based diets. Three dietary treatments containing: 0.10 and 20% CNR at the expense of maize on a weight for weight basis were used. Eighteen weaner rabbits (mixed breeds and sexes) were randomly divided into three groups of six rabbits each in a completely randomized design (CRD). The average daily weight gain, average daily feed intake and feed conversion ratio were not significantly influenced (P>0.05) by the dietary treatments. But rabbits fed 10% CNR based diet had the highest values for average daily weight gain and average daily feed intake while rabbits fed the control diet (0% CNR) had the least value for feed conversion ratio. No mortality was recorded for all the dietary treatments. The feed cost/kg diet (₦), feed cost/kg live weight gain (₦/kg) and cost of feed consumed/day (₦) decreased steadily with increasing level of cashew nut residue meal. The saving on feed cost (%) was not significantly affected (P>0.05) by the dietary treatments, but increased across the groups. However, the saving on feed to produce 1kg live weight was significantly (P<0.05) influenced by the CNR based diets. Rabbits fed 10% CNR based diet had the highest value of 9.66% than their counterparts fed other diets. It is concluded that cashew nut residue could be incorporated into rabbit diet at 10% without compromising the performance

Soybeans in natura can be used in the feed of confined animals as a source of protein and energy. We measured consumption, performance, in vivo biometry, and metabolic profiles lambs fed whole grain soybean in natura. We used Ile de France breed lambs, weaned and confined in a completely randomized design with six repetitions and three treatments: Control, soybean grain (SG) 6.25%, and SG 14% (based on dry matter) in feed. The control and SG 6.25% groups showed higher average daily gain (0.296 kg/day) and total weight gain (17.57 kg) than did the SG 14% group. There were no differences among groups in terms of consumption of dry matter, protein, neutral detergent fiber, acidic detergent fiber, or feed conversion. The inclusion of soybean grain was associated with linear increases in consumption of ethereal extract, and in percentage of live weight. There were no differences among groups in terms of concentrations of studied metabolites. Regarding in vivo biometrics, the control treatment and SG 6.25% groups were superior in terms of conformation and body conditions. Inclusion of soybean whole grain in natura in the feed of confined lambs may be reduced consumption of dry matter and average daily weight gain.

Dried plantain (Musa paradisiaca) peels (DPP), either ripe or unripe (green), were given to Weaned rabbits to replace maize at O, 10, 20 and 30% levels in isonitrogenous (18% crude protein) diets for 56 days in a 2 x 4 factorial experiment. The 30% inclusion level of DPP depressed (P < 0.05) the final weight gain, daily weight gains, and feed conversion efficiency. Ripe or unripe DPP had no significant (P < 0.05) effect on the performance parameters except feed intake, which was improved (P < 0.05). The interaction between ripe or unripe DPP and inclusion levels significantly (P < 0.05) affected weight gain and feed conversion efficiency. Inclusion of DPP depressed (P < 0.05) dressing percentage and lumbar and limbs weights while the viscera weight was increased Ripeness the plantain peels had no significant effect (P < 0.05) on the carcass yield. There was also increase in profit margin expressed in terms of feed cost/ kg live weight gain with inclusion of plantain peel in the diet. The results of this study showed that ripeness slightly improved the nutritive value of DPP which can be included al 20% in weaned rabbits ' diet to replace maize.

An experiment was conducted for a period of 60 days with twelve bull calves with an average live weight of 77.78 ± 10.96 kg to determine the effect of treatment of rice straw with Wood Ash Extract (WAE) on feed intake, nutritive value, growth rate and economic benefits. The experimental animals were divided into three groups A, B and C having four animals in each. They were supplied randomly with three rations following randomized complete block design. All rations were made iso-nitrogenous by using urea as a source of nitrogen. Animals of group A were fed untreated rice straw, whereas, group B and C were fed urea-treated and WAE treated rice straw, respectively. The chemical analysis showed that treatment of rice straw with WAE increased ash content of straw from 13.93% to 16.45% and decreased the NDF content from 67.39% to 63.00%. The daily DM intake per 100 kg live weight of diet B was significantly (P<0.01) higher than that of diet A and C. The daily CP intake per 100 kg body weight of diet B (553.3g) was significantly (P<0.05) higher than that of diet A (449.5g). Similarly, the organic matter (OM) intake in bull calves fed diet B was significantly (P<0.05) higher than those fed diet A and C. The average daily live weight gain with diet B and C was significantly (P<0.01) higher than diet A. The animals fed diet B and C were more efficient in converting feed into live weight than animals fed diet A. Treating rice straw with wood ash extract improved the nutritive value, it significantly (P<0.01) increased the apparent digestibility of DM, OM, CP, ADF and NDF. It also increased the DCP, DOM, DNDF and DADF contents of rice straw compared with untreated straw. Although the total feed cost of untreated group is lower than those of WAE and urea-treated groups, the feed cost per kg live weight gain as well as the feed cost per kg meat production of WAE and urea-treated groups were significantly (P<0.01) lower than that of untreated rice straw. It may be concluded that nutrient composition and digestibility of rice straw and live weight gain of animals can be improved by treating rice straw with wood ash extract.

The effects of treatment with 3.5% anhydrous ammonia on the nutritive value of straws from Neepawa wheat, Bonanza barley and Random oats were investigated with growing Hereford steers. Ambient temperatures during the 6-wk post-treatment period were 0.1 °C for wheat and barley straws and 15 °C for oat straw. The four treatments were untreated and ammoniated straw, fed with or without 4-kg supplements per day over four periods to four steers in a 4 × 4 latin square design. Crude protein was doubled in wheat and barley straws and trebled in oat straw following ammoniation. The consumption of all three straws without concentrates was increased significantly by ammoniation. Apparent digestibility of dry matter and crude fiber on straw rations were higher (P < 0.05) in ammoniated wheat and oat straw than in the corresponding untreated straws. Neither straw intake nor dry matter digestibility were improved (P > 0.05) by ammoniation when supplements were fed, though crude fiber digestibility was increased (P < 0.05) in wheat and oat straw rations. Straw treatment had no effect (P > 0.05) on ruminal pH, dehydrogenase activity, or total or molar proportions of volatile fatty acids. Ruminal ammonia concentrations were higher (P < 0.01) for ammoniated than for untreated straws fed alone and similar to those when concentrates were also fed. Plasma urea, measured 0, 0.5, 1, 2, 4 and 7 h post-prandial, was highest in steers fed ammoniated wheat and oat straw and lowest when untreated straw was fed alone.

AbstractTwo silages were made from a regrowth of perennial ryegr ass following a 24-h wilt using either 2·5 l/t (LF) or 5·5 l/t (HF) of Add Safe (an aqueous solution of ammonium tetraformate, Trouw Nutrition, Cheshire, UK). Composition of silages LF and HF respectively were for dry matter (DM, g/kg) 205, 217; crude protein (g/kg DM) 106, 104; digestible organic matter (g/kg DM) 665, 692, pH 3·8, 3·9; lactic acid (g/kg DM) 103, 84; neutralizing value (meq/kg DM) 1051, 892; acetic acid (g/kg DM) 18·4, 14·0. Experiment A measured the intakes of the two silages using 12 Scottish Blackface wether lambs (mean live weight 25 kg) using a cross-over design with periods of 21 days. Intakes (g DM per day) were significantly greater (P < 0·05) for silage HF (329) than for LF (268). Experiment B measured the voluntary intakes of dried silage residues following juice extraction using the same protocol as for experiment A, except that only six lambs were used. There were no significant differences in composition or intake (P > 0·05) of the dried residues from the two silages. Experiment C used a 5 × 5 Latin-square design to measure the effects on voluntary intake of adding juices from the two silages to unmolassed sugar-beet nuts (SBN) pre-feeding or administered directly into the rumen in two discrete doses per day. Sheep on treatments LED and HFD received juices added to SBN (1·5 l/kg) and water added into the rumen in equal volume to the juice consumed with the previous day’s SBN. Treatments LFR and HFR received water added to the SBN (1·5 l/kg) and juice into the rumen in equal volume to the water consumed with the previous day’s SBN. The control treatment (W) was water added both to the SBN and into the rumen. Total mean daily intakes (g/day) were 1930,1954,1296, 2034 and 1703 (s.e.d. 179) for treatments LED, HFD, LFR, HFR and W respectively. Treatment LFR gave significantly lower mean daily intakes (P < 0·05) than all other treatments. Values for pH, volatile fatty acids and ammonia in the rumen fluid were not significantly affected by treatment (P > 0·05). Differences in voluntary intake for the two silages made from the same crop using different ensilage methods were attributed to differences in the silage liquid and volatile phases and not to the non-volatile solid phase. The effects of juice composition on intake were greater when added directly to the rumen than when added to the diet suggesting that effects on taste or smell were relatively unimportant.

Factorial experiment was carried out to investigate the effect of two factors, molasses (M) and liquid whey (LW) on fermentation characteristics and nutritive value of date palm leaves (DPL). Fresh DPL was chopped into 1-2 cm and treated with treatment solutions prepared by addition of 5, 7.5 or 10% of M together with 3 levels of LW on basis of nitrogen content equivalent to 0, 1 or 1.5% of urea. Ground wheat straw was added to each sample at rate of 50 g. Materials were packed into double nylon sacs and ensiled for 60 days. Samples of DPL were appeared firmly connected and most of them acquired yellowish to light green color with emission of an apple-date vinegar smell. Results revealed that there was a significant (P˂0.01) decrease in dry matter and crude fiber contents with increasing M levels. In DPL silages prepared with 10% of M, these contents were 30.04 and 34.70% respectively. Crude protein content was significantly increased (P˂0.01) from 6.39 to 7.32 and 7.32% for 0, 1 and 1.5% levels of LW respectively. This was associated with a significant (P˂0.05) decrease in fat content. All samples of DPL silages were characterized with good quality as evidenced by fermentation characteristics. There was a significant (P˂0.01) decrease in pH accompanied with an increase (P˂0.01) in ammonia nitrogen concentration. Values ranged between 3.85 to 3.78 and 3.84 to 4.32% of total nitrogen for the 1st and 2nd parameters due to the addition of low and high levels of M respectively. Addition of LW at 1 and 1.5% levels decreased (P˂0.05) pH from 3.85 to 3.81 and 3.81, but concentrations of total volatile fatty acids were increased (P˂0.01) from 2.29 to 2.97 and 3.11% of DM. Results showed that increasing level of M to 7.5 and 10% increased (P˂0.01) DM loss from 12 to 17.78%, but it improved (P˂0.01) aerobic stability. Samples of DPL silages prepared with addition of 1.5% of LW resisted for longer (P˂0.01) period (55.58 hours) before signs of aerobic deterioration were appeared.

SUMMARYThe performance of Israeli-Friesian male calves on six rations, including two levels (15% and 30%) of ground wheat straw and oatvetch hay in pelleted mixtures, and the same two levels of ground straw in non-pelleted mixtures, was examined.Daily live-weight and carcass gain were higher on the lower level of both roughages. The differences in performance on hay and straw were insignificant. Feed intake was higher on the 15% level of both roughages when pelleted but the energy conversion ratio was higher on pelleted rations of both levels of straw.The dressing percentage was higher for animals on pelleted rations. There was no significant difference in percentage fat trim, percentage bone or percentage saleable meat in the carcasses. There was 20% more kidney, pelvic and cod fat on the lower level of roughage.The digestibility of organic matter was higher on rations with the lower level of roughage, and on the pelleted rations compared with the non-pelleted at equal level of roughage. This was not the case for the digestibility of crude fibre. Nitrogen retention was significantly higher on the lower levels of straw and on the pelleted rations of a similar level, and was higher on hay rations than on straw rations. Ration differences in the molar proportions of volatile fatty acids in the rumen liquor were detected.Pelleting appeared to improve the nutritive value of straw.

Fat supplementation affects the lactational performance of goats and dramatically changes milk nutritive value. In the present experiment, two levels of Nannochloropsis oculata microalgae, a natural source of rumen-protected eicosapentaenoic acid (EPA), were studied in the diet of Nubian goats. Using quintuplicated 3 × 3 Latin square design, fifteen lactating goats, (14 ± 2 months old and 33.0 ± 1.3 kg) after kidding, were randomly assigned into three treatments in an 84-d assay. Goats were offered a basal diet comprising berseem clover, wheat straw and concentrates in 3:2:5, respectively, (control treatment-no supplementation). The other two treatments were supplemented with N. oculata microalgae at 5 g (NOM5 treatment) or 10 g (NOM10 treatment)/doe/d. Without affecting intake, treatments improved (p < 0.01) nutrient digestibility. Supplementations had no effect on ruminal pH and ammonia-nitrogen, however, NOM5 and NOM10 linearly improved (p < 0.05) total volatile fatty acids and propionic acids. N. oculata supplementation linearly increased (p < 0.01) milk yield and lactose content. Supplementation reduced atherogenic index (p = 0.004) and enhanced the concentrations of unsaturated fatty acids and C20:5n3 (EPA). Conclusively, feeding Nubian goats on diet supplemented with N. oculata at 5 and 10 g improved milk production and the nutritive value. No improvements in the performance were observed when N. oculata dose was increased from 5 g to 10 g/doe; thus, 5 g dose is recommended for use.
