Crossbred Pigs

Two experiments of a factorial design (sex × treatment) were conducted to determine the effects of enzyme and salinomycin supplementation on the nutritive value of barley or rye-based diets for growing pigs fed from approximately 20 to 85 kg. For exp. 1, 72 crossbred pigs were fed either a barley-based control diet or a similar diet supplemented with enzyme (Aspergillus niger; 750 units g−1 beta-glucanase and 650 units g−1 pentosanase), salinomycin (25 ppm) or both additives in combination. For exp. 2, two replicates of 48 pigs were fed either a barley-based diet, an unsupplemented rye-based diet or a rye-based diet supplemented with enzyme, salinomycin or both additives. During both experiments, chromic oxide (0.5%) was added to the diet of four to six pigs/treatment to act as a digestibility indicator starting when the pigs reached 42 kg. Neither enzyme nor salinomycin, alone or in combination, significantly improved the growth rate or feed efficiency of pigs fed barley or rye. Supplementation of barley with the combination of additives significantly (P < 0.05) improved protein digestibility while neither enzyme nor salinomycin had any effect on nutrient digestibility when fed alone. In rye-based diets, salinomycin, both alone and in combination, significantly (P < 0.05) improved the digestibility of crude protein and energy. Dry matter digestibility of the rye-based diets was unaffected by treatment. Key words: Swine, rye, barley, beta-glucanase, pentosanase, salinomycin

Randomized Block Design

Sixteen crossbred growing pigs Duroc x Landrace, (10 weeks of age; initial body weight 27 ± 3.92 kg) were allotted into four treatments in a randomized block design to evaluate the effects of inclusion of fermented kepok banana corm (FKBC) in the diet on the nutrient digestibility of growing pigs. There were four treatments diets offered:  basal diets without FKBC (RO); basal diets + 7% FKCB (R1); basal diets + 14% FKCB (R2); basal diets + 21% FKCB (R3). Inclusion of 21% FKBC in the diet of pigs significantly reduced (P <0.01) dry matter intake and organic matter compared to the control diet. There were no significant different between 14% and 21% FKCB on the intake and digestibility of dry matter and organic matter of the pigs. However, inclusion of FKCB at the level of 7% showed the optimum digestibility of dry matter, organic matter, crude protein, and energy with the average value of 66.57%, 70.48%, 83,43% and 70,76%, respectively. In addition, mineral consumption and retention of Ca and P were 14.3 and 9.1 g/h, respectively with the value of mineral retention both Ca and P were 11.9 and 7.5 g/h, respectively. It can be concluded that inclusion of FKCB at the level of 7% increased dry matter digestibility and organic matter.

Cassava Peels

The nutritive value ,voluntary dry matter intake, and the nutrient digestibility of graded levels of Gmelina arborea and cassava peels concentrates in WAD sheep was investigated. Twelve WAD sheep aged 1-2 years old and weighting 14.00± 0.45 kg were used in a complete randomized design. Diets were formulated such that cassava peels was replaced with Gmelina arborea leaf meal at 0, 33.33, 66.67, 100% levels, designated as diets A, B, C, and D respectively. Diet without Gmelina arborea leaf meal was tagged the control diet. The concentrate feed was compounded to contain 16% CP. Diets with 33.33% inclusion level of Gmelina arborea had significantly (P<0.05) higher dry matter intake (DMI) 598.80g day-1, while the lowest DMI 425.00g day-1 was obtained in animals fed 100% inclusion level of Gmelina arborea. Crude protein intake (CPI) of animals fed diets with 33.33% inclusion levels of Gmelina arborea were significantly (P<0.05) highest, followed by 66.67% inclusion level and the least was observed in 0% inclusion level of Gmelina arborea. Dry matter digestibility (DMD) was significantly (P<0.05) different across the dietary treatments, animals placed on diets with 33.33% inclusion level had the highest DMD, followed by animals on diets with 66.67, 100 and 0% inclusion levels. CP digestibility (P<0.05) increased from 33.33% to 100% inclusion levels of Gmelina arborea leaf meal, the lowest CP digestibility was observed at 0% inclusion level. CF digestibility (P<0.05) increased from 33.33% to 100% inclusion levels of Gmelina arborea leaf meal, while the lowest CF digestibility was observed at 0% inclusion level. N intake increased significantly (P<0.05) with increase in the level of Gmelina arborea inclusion from 33.33% to 100%. N retention was significantly (P<0.05) different, diets with 33.33% Gmelina arborea inclusion had the highest value (64.36g day-1) followed by 66.67%, 100% and the least (52.64g day-1) was at 0% inclusion level of Gmelina arborea.  N balance values also followed the same trend. From the results of this study, it can be concluded that the inclusion of Gmelina arborea leaf meal in WAD rams diet was well tolerated without adverse effect on acceptability, intake and nutrient digestibility, and inclusion level of 33.33% is hereby recommended in ruminants diet for optimum performance and productivity.

Protein Concentrate

In two digestibility and balance trials with growing pigs, whey protein concentrate (WPC) was compared as a protein supplement with casein (CAS) and dried skim milk (DSM), and, 30 % lactose (40 % dried whey, DW) was compared as a sugar supplement with the same amounts of hydrolysed lactose (HYLA) and sucrose (SUC). The effects of these supplements on protein and mineral metabolism of the pigs were investigated, WPC contained 42.2 % crude protein and had a high content of lysine, 8.6 g, and sulphur containing amino acids: cystine 2.8 and methionine 2.2g/16 g N, These exceeded the values for DSM. The hydrolysing degree of the enzymatically treated lactose syrup was 73 %. WPC had high crude protein digestibility, 99.1 % as compared to 95.4 for CAS and 95.0 % for DSM. Dried whey had low crude protein digestibility, 72.5 %. The amino acids in the WPC diet were highly digestible, but low values were obtained for the DW diet. On the WPC diet, nitrogen retention was higher than with the other protein supplements (P > 0.05), urinary urea excretion was low and the biological value very high. On a combination of WPC and HYLA protein utilisation was higher than on dried whole whey. On the diets supplemented with different sugars, none of the blood parameters differed statistically significantly (P > 0.05) and all values lay within the reference range. Water intake was on average 49 % greater on diets with sugar supplements than without. Urinary excretion of reducing sugars averaged 40.2, 8.3 and 6.6 g/d on the HYLA, SUC and DW diets, while on the diets without sugar supplements the values were 0.8—1.2 g/d. The following mean daily mineral retention values were obtained: P 4.0 g, Ca 5,9 g. Mg 0,4 g, Na 1.9g, K 2.9 g, Fe 27 mg, Cu 6.4 mg, Zn 65 mg and Mn 4.0 mg. The surplus Na and K on the DW diet were excreted in the urine and the pigs did not have diarrhoea.

The study investigated gut ecology and morphology of the Indonesian indigenous crossbred chickens (IICC) supplemented with the combination of formic acid and Saccharomyces cerevisiae. Two hundreds day-old IICC were distributed to T0 (control diet), T1 (T0 + 0.2% formic acid), T2 (T0 + 0.3% S. cerevisiae), T3 (T0 + 0.2% formic acid and 0.3% S. cerevisiae). Excreta was collected at week 8, while intestinal ecology and morphology were determined at week 9. In duodenum, T3 chicks showed higher and wider (P<0.05) villi. The T2 and T3 chicks showed deeper (P<0.05) crypt than that of T0. The jejunal villi was higher (P<0.05) in T3 than in T0. The T3 chicks had deeper (P<0.05) crypt compared to other groups. In ileum, the villi height was lowest (P<0.05) in T0. The crypt was deeper (P<0.05) in T3 than in other. Crude protein digestibility coefficient was highest (P<0.05), while fecal protein was loswest (P<0.05) in T1 than in other groups. Compared to T0, the treated IICC showed higher (P<0.05) weight gain and feed intake with T3 had the highest gain and intake but gain:feed rasio was the lowest (P>0.05). IIn conclusion, the inclusion of formic acid and S. cerevisiae in diets improved intestinal ecology and morphology. The IICC chickens fed with formic acid and S. cerevisiae exhibited improved growth performance and nutrient digestibility.

Twenty growing pigs with an average initial weight of 53±0.5 kg (± SE) were randomly assigned to five dietary treatments in a completely randomized design with four replicates per treatment and one animal in each replicate. A total tract digestibility trial was carried out to determine the effect of partial replacement of maize with graded levels of high quality cassava peel (HQCP) mashon the nutrient digestibility and fibre fraction digestibility of growing pigs. The control diet T1 had 40% of maize, while the dietary treatments T2, T3, T4 and T5 had7.5, 15, 22.5 and 30% of HQCP corresponding to replacement of maize by 0, 19, 38, 56 and 75% respectively. There was no significant difference (P>0.05) in apparent nutrient digestibility coefficient of dry matter, nitrogen free extract, organic matter and energy. There were significant(P<0.05)variationsintheapparentdigestibilityofcrudeprotein,crudefibreand ether extract and the crude protein digestibility decreased as the level of HQCP increased from 7.5 to 30%. Also, there was a significant (P<0.05) increase in acid detergent fibre and acid detergent lignin digestibilities with the inclusion of HQCP compared to the control, whereas there was no significant (P>0.05) influence of HQCP inclusion on hemicellulose digestibility among the treatments. It can thus be concluded that the nutritional potential of high quality cassava peel can still be realised when fed up to 30% in growing pig diet

Voluntary Intake

SUMMARYTwenty-seven sheep feeding trials were carried out on freshly cut Andropogon gayanus, fed daily during three wet seasons, 1966–8.In each year, dry-matter voluntary intake and digestibility were highest during the first part of the growing season and declined with advancing maturity of the herbage. However, at the time of ear emergence in early October, there were small increases in voluntary intake of dry-matter and crude protein digestibility, although further decreases followed after mid-October.Determinations of in vitro digestibility indicated that elongating stems during early October were at least as digestible as leaves.Seasonal changes in crude protein digestibility were much greater than changes in dry-matter digestibility; seasonal changes in feed intake were intermediate. Voluntary feed intake was related to dry-matter digestibility.Voluntary feed intake and digestible crude protein were both closely related to the crude protein content of the forage. It was concluded that crude protein is a useful criterion for predicting nutritive value.

ABSTRACTThe effects of feeding monensin and amicloral at 33 and 1500 mg/kg of diet, respectively, were investigated in two experiments using 330-kg steers. Monensin and amicloral, either alone or in combination, increased the digestibility of organic matter and crude fibre compared with a control diet (P< 0·001). Crude protein digestibility was increased by monensin (P< 0·001). Use of monensin and amicloral, alone or in combination, increased molar proportions of propionic acid by 22% on average (P> 0·05), and monensin decreased butyric acid by 37% (P< 0·05).Ruminal ammonia concentrations were lower in steers fed monensin (P< 0·05). Steers fed monensin consumed 6 % less feed, gained 9 % more weight (P< 0·05) and utilized feed 14% more efficiently (P< 0·05) than control animals. Amicloral, either alone or with monensin, lowered feed intake by 11 % (P< 0·05), had no effect on average daily gain and improved feed efficiency by about 12% (P< 0·05). There were no treatment effects on any of the carcass parameters.

Protease Enzyme

The study evaluated supplementation of broiler diets with a protease enzyme. Six hundred Ross 308 female broiler chicks were acquired at one day of age and randomly distributed to three treatments with five replicates of 40 chicks each. The experimental treatements consisted of i) a positive control diet with normal levels of crude protein, digestible lysine and digestible sulphur containing amino acids (PC); ii) a negative diet with reduced levels of crude protein, digestible lysine and digestible sulphur containg amino acids (NC); and iii) the NC diet augmented with Ronozyme ProAct protease at 200 mg/kg (NC+ENZY). Compared to the other diets, feeding the PC produced the highest final bodyweight (BW), bodyweight gain (BWG), and feed intake (FI) and best feed conversion ratio (FCR) over 0 - 42 days. The PC diet also produced the highest hot and cold carcass yields, ileal protein digestibility and improved the serum biochemistry parameters. Relative to the NC, the NC+ENZY diet increased BW, BWG and FI, improved FCR, increased ileal protein digestibility, hot and cold carcass yields, and the crude protein content of meat. However, it decreased serum triglyceride and very low density lipoprotein (VLDL) cholesterol levels and the crude fat content of meat of broilers. As a result, protease supplementation at the level of 200 mg/kg may not remove the detrimental effects that are caused by a 6% reduction in crude protein and digestible amino acids on performance, hot and cold carcass yields and ileal digestibility of crude protein of broilers.

The current study was aimed to evaluate the ability of phenol content in cashew nutshell liquid (CNSL) in binding protein and its effect on in vitro nutrient digestibility. This research divided into three steps, there were determination of total phenol and tannins content in CNSL, optimalization binding of CNSL tannin to bovine serum albumin with the determination of protein-percipitable phenolics compound and protein content using Lowry method, after that amount of optimalization supplementation of CNSL was used for measuring on in vitro nutrient digestibility by Tilley and Terry method. The results showed that phenol and tannin content of CNSL were 148.69 g/100 ml and 28.3 g/100 ml. One gram tannin in CNSL could be bound by 65.83 g protein. Optimum tannin were used in this study was 5.85 g tannin or equivalent to 163.91 mg of CNSL. Amount of CNSL were used in various levels, there are 0, 50, 100, 150 dan 200 mg. CNSL supplementation reduced dry matter, organic matter crude protein digestibility in rumen, and didn’t reduce dry matter dan crude protein in vitro post rumen digestibility. Supplementation of CNSL increased feed efficiency on in vitro.

Growth Trial

The supplementation of Peace River barley was investigated in both a growth trial and a metabolism trial. The control diet consisted essentially of barley and soybean meal and provided 15.8% crude protein containing 0.75% total lysine. In the other diets, barley, as the sole source of protein, was supplemented with L-lysine HCl to provide 0.75 and 0.90% total lysine, with the former level also tested with 0.05% added L-threonine, alone or with 0.10% DL-methionine or with 0.10% DL-methionine plus 0.10% L-isoleucine. The growth trial incorporated three replicates, each with three gilts and three barrows group-fed on each diet, whereas in the metabolism trial, six observations per diet were made. The control diet produced greater daily gain, better feed utilization and leaner carcasses than any of the amino acid-supplemented diets. Gilts, but not barrows, grew more rapidly with the increase in lysine content from 0.75 to 0.90%. Addition of 0.05% L-threonine to the 0.75% lysine diet to provide 0.29% total threonine significantly improved daily gain and feed efficiency. Addition of methionine either with or without isoleucine to this latter diet had no effect on growth or feed utilization, but slightly improved nitrogen retention. Although nitrogen retained (expressed as a percentage of nitrogen absorbed) for all diets containing threonine was greater than the value for the control diet, values for nitrogen digestion and total nitrogen retention were less than for the latter diet.
