PSIV-13 Supplemental phytase increases phosphorus digestibility in pigs regardless of phytase source or feed pelleting

Abstract Two experiments were conducted to investigate the effects of phytase source and feed pelleting on digestibility of dry matter (DM), crude protein, organic matter (OM), and phosphorus (P) with different doses of phytase in pigs. In Exp. 1, ten barrows (31.4 ± 3.5 kg of BW) were individually housed in metabolic crates and allotted to a replicated 5 × 6 Latin square design with 5 diets and 6 periods. In Exp. 2, ten barrows (28.2 ± 3.2 kg of BW) were individually housed in metabolic crates and allotted to a replicated 5 × 5 Latin square design with 5 diets and 5 periods. Each period lasted 10 d consisted of a 5-d adaptation and a 5-d collection periods and the marker to marker method was used for fecal collection. In both experiments, a basal diet was prepared based on corn and soybean meal without phytase or inorganic P. Four additional diets were prepared in a 2 × 2 factorial treatment arrangement with 2 phytase sources (Buttiauxella spp. or Escherichia coli) and 2 feed forms (mash or pellet). Both experiments employed the same treatments but had different supplemental phytase doses (500 and 1,500 FTU/kg in Exp. 1 and 2, respectively). In Exp. 1, supplemental phytase increased standardized total tract digestibility of P (66.1 vs. 51.7%; P < 0.001) with no effects of phytase source or feed pelleting. Feed pelleting increased digestibility of DM, crude protein, and OM (P < 0.001). In Exp. 2, supplemental phytase increased standardized total tract digestibility of P (72.8 vs. 44.8%; P < 0.001) with no effects of phytase source or feed pelleting. Feed pelleting increased digestibility of DM and OM (P < 0.001). Taken together, supplemental phytase at 500 and 1,500 FTU/kg increases P digestibility regardless of phytase source or feed pelleting.

Since rice straw is seasonal and low quality roughage, thus, a supplementation for it is needed. Lamtoro leaf meal (LLM) and soybean meal (SBM), have both soluble and bypass protein, so it enough potential to supply nutrients to optimize of rumen microbes and improve animal performance. Supplementation with LLM or SBM significantly increased dry matter, organic matter, crude protein and crude fiber intake (P<0.05). This fact showed that LLM or SBM supplementation made an improvement of rumen fermentation by microbes. Comparison between LLM and SBM to basal diet clearly showed that basal diet was the lowest (P<0.05) nutrient intake and nutrient digestibility, however, the animal fed basal diet degraded crude fiber was not affected. It has been shown that supplementation with lamtoro leaf meal or soybean meal were palatable, fermentable and reasonably digestible. Therefore, the use of these feedstuffs as supplement to rice straw are strongly recommended. Key words : concentrate, PO beef cattle, performance, digestibility

Sunflower Cake

The objective of this study was to evaluate the effect of the inclusion of sunflower cake replacing soybean meal in beef cattle diets on the in vitro digestibility of dry matter (IVDDM), organic matter (IVDOM), crude protein (IVDCP) and the ruminal fermentation kinetics and parameters. The experiment was analyzed according to a completely randomized design. The treatments consisted of four levels of sunflower cake, 0, 200, 400, 600 g kg-1, replacing soybean meal in the concentrate of beef cattle diets. The coefficients of IVDDM, IVDOM and IVDCP presented a quadratic effect with the addition of sunflower cake. The soluble fraction (fraction B) degradation rate and total gas production decreased linearly with the inclusion of sunflower cake. Values of pH in ruminal fluid were higher for levels 0, 200 and 600 g kg-1 sunflower cake. Sunflower cake can replace soybean meal by up to 280 g kg-1 in the concentrate of beef cattle diets, improving the in vitro digestibility of dry matter organic, matter and crude protein. Levels above 400 g kg-1 reduce ruminal digestion rate, digestibility and release of final fermentation products.

In an experiment of 3 x 3 Latin Square design, 3 heifers each fitted with rumen and simple T-piece duodenal cannulae were used to determine the effects of method of processing soyabean meal (SBM), and low (LRSM) and high (HRSM) glucosinolate rapeseed meals on rumen degradabilities (RD) and intestinal digestibilities of dry matter (DM), nitrogen (N) and organic matter (0M) using a mobile nylon bag technique.Heifers were given a basal diet of hay (0.55 of DM intake) and mineralized barley with LRSM (0.45 of DM intake) to provide a ME intake of > 2 x maintenance. The diet was offered twice a day and a period of four weeks was allowed before the experiment. Methods of processing were formaldehyde (FT, 0.8 HCH0/l6g N), heat (HT, 110°C for 2 h) and untreated (UT). After processing the feedstuffs were ground and 1g samples were placed in sealed nylon bags (3-5 x 5.5 cm). The bags were placed in a plastic mesh cylinder and incubated in the rumen for 0, 12, and 24 hours.

Alfalfa Meal

Eight sheep were used in two 4 × 4 latin square digestion trials substituting alfalfa meal with unsteamed or steamed muka (foliage) at levels of 20, 40 or 60%. Including muka at all levels depressed (P < 0.05) the digestibility of dry matter, organic matter, crude protein and acid detergent fiber compared with the control alfalfa meal diet. When calculated by difference, the digestibility of muka dry matter and organic matter was not affected (P < 0.05) by either the level of its inclusion in the diets or by steaming. The mean dry matter and organic matter digestibilities of muka were 29.2 and 30.4%, respectively. The protein content of muka was 5.0% and the estimated protein digestibility at the 60% level of inclusion was only 6.6%. With unsteamed muka, the digestibility of acid detergent fiber calculated by difference averaged −11.9%, suggesting the presence of factors which depressed the digestibility of fiber in the basal diet. Steaming appeared to reduce this depression. A growth trial was conducted with lambs where alfalfa meal, as the sole roughage source, was compared to the same diet with 20% of the alfalfa replaced by steamed muka. Growth rates were not different (P > 0.05) being 142 and 138 g/day, respectively. A taste panel evaluation of the carcasses found no adverse effects on flavor due to the inclusion of steamed muka in the diet. Key words: Lodgepole pine muka, nutritive value, sheep

The current study evaluated the influence of a multi-carbohydrase and phytase complex (MCPC) on the ileal and total tract digestibility of nutrients in growing pigs. A total of eight barrows (initial BW = 30.7 ± 1.1 kg) were surgically fitted with a T-cannula at the distal ileum and randomly allotted to four groups. The experiment was conducted according to a 4 × 4 Latin square design, each period lasting 10 days. Pigs were fed four experimental diets, which consisted of two basal diets (BD1, low phytate; BD2, high phytate) with or without MCPC containing at least 1800 U xylanase, 6600 U α-arabinofuranosidase, 1244 U β-glucanase, and 1000 U phytase per/kg corn–soybean meal with 15% corn distillers based diet. The high phytate diet reduced (p < 0.05) the apparent ileal digestibility (AID) of crude protein by 1.4% and the apparent total tract digestibility (ATTD) of organic matter, crude protein, and gross energy by 1.7, 2.3, and 1.9%, respectively, and tended to decrease (p = 0.10) the ATTD of Ca by 17.3%, relative to the low phytate diet. The dietary supplementation of the MCPC increased (p < 0.05) the AID of phosphorus (P) and calcium (Ca) by 34.2% and 31.1% for BD1 and 26.7% and 41.3% for BD2, respectively, and increased (p < 0.05) ATTD of crude fat, P, and Ca by 1.4%, 45.6%, and 9.6% for BD1 and 3.1%, 66.0%, and 52.7% for BD2, respectively. The MCPC supplementation did not significantly increase the AID and (or) ATTD of crude protein, organic matter, and starch. In conclusion, the dietary supplementation of the MCPC could improve the AID of P and Ca and the ATTD of crude fat, P, and Ca.

Objectives The aim of the study was to evaluate overall dry matter, organic matter, crude protein, crude fat and gross energy digestibility of a feline commercial raw diet and a homemade raw diet compared with a canned, heat-processed diet. Methods Six domestic shorthair kittens (20–28 weeks old) were fed three different diets in a Latin square crossover design. Diet A was a commercially available, canned, heat-processed diet. Diet B was a complete commercial, prefrozen, raw diet (commercial raw), and diet C was a raw diet supplement mixed with ground raw meat obtained locally (homemade raw). Both diets A and B were formulated to meet nutritional profile levels for cats at all life stages. Kittens were given specific diet amounts to maintain a 2–4% weight increase per week. Food was measured before and after feedings to determine the amount eaten, and all feces were collected, weighed and frozen prior to submission. Composite food samples and all feces were submitted to a national laboratory for proximate analysis of crude protein, crude fiber, ash, crude fat, moisture and caloric density. Results Significantly higher digestibility of dry matter ( P <0.001), organic matter ( P <0.001), crude protein ( P <0.001) and gross energy ( P <0.001) was seen in the raw diets compared with the heat-processed diets. This difference resulted in significantly less fecal matter ( P <0.001) despite similar levels of intake and kcal ingested, and evidence of no difference in fecal scores. Conclusions and relevance Higher dry matter, organic matter and protein digestibility was seen in two commercial raw diets compared with a heat-processed diet. Digestibility differences could have been due to variance in dietary protein, fat and carbohydrate concentrations between the diets, variance in dietary ingredients or quality, alterations in protein structure secondary to heat processing, as well as alterations in gastrointestinal flora. Future research examining digestibility in diets with the same macronutrient proportions and ingredients, and mechanisms for any differences, is warranted.

Forage Harvester

Corn stover stacks were harvested and a portion of these were treated with anhydrous ammonia at a level of 3% of dry matter (DM) and left covered with plastic for at least 30 days during the fall of 1977. In the spring, both treated and untreated corn were chopped through a forage harvester. A portion of each was then ground through a 1.3-cm screen. Treatments were: untreated chopped, untreated ground, ammoniated chopped, ammoniated ground. Treatments were evaluated with eight Hereford-Angus yearling steers in a double 4 × 4 latin square design. In addition to the stover, rations contained 10% molasses, 6% soybean meal, and 2.3% mineral mix. Urea was added to the untreated rations at the level of 1.6% to make rations isonitrogenous. Steers were injected with vitamins A, D and E at 90-day intervals. With both control and ammoniated rations, grinding increased (P < 0.001) intake on a body weight raised to the 0.75 power basis (MBW) of DM, digestible energy (DE) and digestible DM by 47%, 39%) and 39%), respectively. With both chopped and ground stover rations, ammoniation increased (P < 0.001) intake of digestible DM and DE and increased (P < 0.01) intake of DM all on a MBW basis by 22%, 31% and 12%), respectively. However, grinding decreased digestibilities of DM and neutral detergent fibre (NDF) (P < 0.001) and of organic matter (OM) (P < 0.01) by 5%, 10% and 5%, respectively. With both chopped and ground stover rations, ammoniation increased (P < 0.001) digestibility of DM, OM, and NDF by 9%, 9% and 14%, respectively. Ammoniation plus grinding increased (P < 0.01) intake (MBW) of DM, digestible DM and DE by 64%), 71% and 85%), respectively, over untreated chopped rations. Grinding increased (P < 0.01) rumen acetate 0.5 h preprandially but did not significantly affect other rumen parameters measured preprandially or 2 h postprandially. Ammoniation increased (P < 0.01) rumen propionate 0.5 h preprandially but did not significantly affect the remaining rumen parameters. Before versus after feeding levels of rumen metabolites did not differ except for an increase (P < 0.01) in ammonia-N and total VFA postprandially. No significant treatment interactions were present.

A trial involving a 2x2 factorial design was conducted to evaluate the effect of corn silage hybrids and concentrate levels (25 and 50%) on intake and digestibility of nutrients, ruminal characteristics and microbial efficiency in steers. Four ruminal and abomasal cannulated steers (512±25kg of birth weight), were used in a 4×4 Latin square design. Treatments consisted of 75% silage A + 25% concentrate; 50% silage A + 50% concentrate; 75% silage B + 25% concentrate; and 50% silage B + 50% concentrate on dry matter (DM) basis. There were no differences in the intakes of DM, organic matter (OM), crude protein, and ether extract. The intake of non fiber carbohydrates and total digestible nutrients were positively affected by concentrate levels. The digestibility of DM and OM were also positively affected by concentrate levels. There were no effects of treatments on ruminal pH values, ruminal ammonia-N, and microbial efficiency.
