Copper Supplementation

The digestive utilization of minerals in Cu- and phytase-supplemented diets by weanling pigs was investigated in an experiment with a 3 × 2 factorial arrangement of treatments. Three levels of Cu (0, 60 and 120 mg kg−1 as CuSO4∙5H2O) and two levels of phytase activity (0 and 1500 units kg−1) were added to a corn-soybean meal basal diet. Seventy-two pigs (gilts:bar-rows, 1:1) with an average initial weight of 9.7 kg received the six diets for 21 d, after which 36 of the pigs were used in an 8-d mineral balance study. Phytase supplementation of diets increased serum P, Zn and Mg concentrations but reduced serum Cu concentration. The addition of Cu to the diets produced serum concentrations of minerals similar to Cu-unsupplemented diets. Absorption and retention of Ca and P were both slightly increased in pigs fed the phytase-supplemented diets compared with pigs fed diets that did not contain phytase. Addition of phytase to the diet that was not supplemented with Cu doubled (P < 0.1) Cu retention. Copper supplementation of diets did not affect absorption and retention of Ca, P, Zn, and Mg but increased absorption and retention of Cu and Mn. Results indicate that addition of phytase to P-supplemented and Cu-unsupplemented diets improves digestive utilization of P and Cu. Key words: Pigs, phytate, copper, phytase, minerals

Three groups, each of five pigs, of initial age 5–6 weeks and initial weight 12 kg, were placed on each of three wheat-soybean-meal-based diets of 18% crude protein content. The diets contained either (a) no antibiotic, (b) 110 mg/kg chlortetracycline hydrochloride, 110 mg/kg sulfamethazine and 55 mg/kg penicillin, or (c) diet (b) minus penicillin. Both antibiotic treatments produced a similar growth response of approximately 12%, which resulted partly from an increased feed intake and partly from an improved efficiency of feed utilization.

Nutrient Digestion

An experiment was carried out to examine the effects of supplementing diets for weanling pigs with oligosaccharides and LAC on nutrient digestion and bacterial populations and metabolites in the small intestine. Twelve barrows, weaned at 28 d, were fitted with a simple T-cannula at the distal ileum. The BW of the pigs at weaning and at the conclusion of the experiment were 9.1 and 13.8 kg, respectively. The pigs were fed four diets based on barley, wheat and soybean meal according to a two-period change-over design. The diets were formulated to contain 18% CP. Transgalactosylated oligosaccharides (0.2%), GUO (0.2%) and LAC (1%, 4-O-β-D-galactopyranosyl-D-sorbitol) were included at the expense of corn starch. Supplementation with oligosaccharides or LAC had little effect on the apparent ileal digestibilities of AA and monosaccharides. Supplementation of diets with oligosaccharides or LAC did not affect (P > 0.05) the monosaccharide concentrations in ileal digesta except for galactose which was higher (P < 0.05) in digesta from pigs fed the diet supplemented with LAC. The daily ileal output of monosaccharides, pH, ammonia and VFA concentrations, bacterial populations in ileal digesta and incidence of diarrhea were not affected (P > 0.05). Therefore, the supplementation of diets for weanling pigs (9.1–13.8 kg) with oligosaccharides or LAC at these levels does not affect nutrient digestibilities and bacterial populations in the small intestine.

Diets containing canola and soybean meal as the only source of protein and containing no supplemental niacin, choline or thiamine were fed to male broiler chickens from 1 wk to 6 wk of age. Supplementation of the basal diet with various levels of the vitamins failed to significantly alter weight gain, gain:feed ratio or percent bone ash values. Examination of the birds for leg deformities and difficulty in walking showed no difference between the basal and the vitamin-supplemented diets. It was concluded that the three vitamins investigated would not be factors in problems arising from the substitution of canola for soybean meal in practical type broiler diets.

An α-tocopherol supplementation study was conducted with 12 Holstein cows, assigned to one of three dietary α-tocopherol levels, 0, 700, and 3000 IU cow−1 d−1, as dl-α-tocopheryl acetate. Cows were fed a basal diet of alfalfa silage and a barley-corn-soybean meal grain mix. The study consisted of a pretreatment (wk 0), a treatment (wk 1 to 5) and a posttreatment phase (wk 6 and 7). Peak milk α-tocopherol levels were observed at wk 1 for the 700 IU group and at wk 2 (P < 0.05) for the 3000 IU group. During wk 2 to 5 milk α-tocopherol concentrations were highest for the 3000 IU group and peaked at 22.0 μg g−1 lipid; plasma α-tocopherol levels increased by 0.7 and 1.3 μg mL−1 for the 700 and 3000 IU groups. By the end of the posttreatment phase, milk α-tocopherol concentrations had returned to wk 0 levels. A field study was conducted of four herds (142 cows) with a chronic spontaneous oxidized flavor (SOF) milk problem. The herds were fed α-tocopherol at 0, 700 and 3000 IU cow−1 d−1 in a changeover design of 2-wk periods followed by access to spring pasture for 4-wk. Milk flavor improved when higher levels of α-tocopherol were fed and SOF was minimal when pasture was grazed. The percentage of cows in the herds producing SOF milk was 68, 61, 56, and 8 for the 0, 700 and 3000 IU d−1 treatments and pasture, respectively. α-Tocopherol levels were highest (P < 0.05) in milk for the 700 IU d−1 level of feeding and in plasma (P < 0.05) when pasture was consumed. Milk and plasma α-tocopherol levels did not correlate well with improved flavor scores. Key words: Spontaneous oxidation, milk, α-tocopherol, dairy cow, flavor, vitamin E

Four trials, involving a total of 426 Yorkshire pigs weaned at approximately 25 days of age, were conducted to measure the effect of including fish meal, dried skimmilk and copper, and of varying the protein level, in diets based on corn and soybean meal, on pig performance. The inclusion of 5% fish meal, 5% dried skimmilk or a combination of the two did not consistently alter pig performance when compared with a corn-soybean meal basal diet of a similar protein content. Levels of protein above 21.9% (dry matter basis) in the starter period did not alter pig performance. In the two trials in which 0.05% copper sulfate was added to the diets, it increased rate of gain. Seventeen pigs out of a total of 144 pigs in one trial died. Various of the following lesions were observed in the dead pigs: hepatosis dietetica, mulberry heart disease, exudative diathesis and ulcers. There was an apparent inverse relationship between the incidence of death and the protein or selenium content of the diet.

Abstract A 16-wk growth trial was conducted to examine the effects of dietary replacement of fish meal by defatted soybean meal (SBM) and fermented soybean meal (FSBM) with taurine supplementation on growth performance, nutrient apparent digestibility coefficient (ADC) and biological parameters of pompano fish. The FSBM was produced by fermenting SBM with Lactobacillus spp. Seven isonitrogenous and isoenergetic diets were formulated to replace 35% or 50% of fish meal by SBM or FSBM with taurine supplementation. The diets are denoted as follows: FM, SBM35, SBM35T, FSBM35T, SBM50, SBM50T, and FSBM50T. The FM (the basal diet) contained fish meal as a main source of dietary protein. Taurine was supplemented to SBM35T, FSBM35T, SBM50T, and FSBM50T at the level of 15 g/kg diet. Pompano juveniles with an initial body weight (BW) of 80 g reared in floating net cages were fed the experimental diets twice daily for 16 wk. Results showed that the final BW, weight gain, and feed conversion ratio of fish fed SBM35 and SBM50 were significantly lower than those of fish fed FM (P &lt; 0.05), indicating that the replacement of fish meal by SBM at the rate of 35% in the diet is excessive for pompano. Supplementation of taurine to the SBM-included diets significantly increased growth performance and feed utilization (P &lt; 0.05); however, these diets did not restore the performance back to a level equivalent to that of fish offered the basal diet. Meanwhile, fish fed FSBM35T had comparable growth and feed performances to those fed FM. Hematocrit values, total biliary bile acid levels, whole body lipid contents, and tissue taurine concentrations of fish fed SBM35 and SBM50 were the lowest among the treatments, but these parameters were improved by taurine supplementation and FSBM inclusion in the diet. Taurine supplementation increased lipid ADC, and SBM fermentation slightly enhanced both lipid and protein ADCs of the fish. These findings suggest that the combination of FSBM and taurine supplementation is an effective way to improve growth performance, nutrient digestibility, and biological parameters, and that FSBM with taurine supplementation can replace 35% of fish meal in pompano diets without any negative effects on growth and feed performances in a long-term feeding period.

Abstract Two experiments were conducted to evaluate the digestible energy (DE), metabolizable energy (ME), and standardized ileal digestibility (SID) of amino acids (AA) in dried yeast (DY) and soybean meal (SBM) fed to pigs. In Exp. 1, 30 barrows with an initial body weight (BW) of 20.7 ± 1.01 were assigned to 5 diets in a randomized complete block design with period and BW as blocking factors. A basal diet was prepared to contain corn, canola meal, and soybean oil as energy-contributing ingredients. Four additional diets were prepared by adding 5 or 10 g/kg DY or SBM at the expense of energy-contributing ingredients in the basal diet to estimate the DE and ME in test ingredients by regression analysis. On a dry matter basis, estimated DE and ME in DY were 4,022 and 3,352 kcal/kg, respectively, and those in SBM were 3,876 and 3,601kcal/kg, respectively. There was no difference in estimated DE or ME between DY and SBM. In Exp. 2, 21 barrows (initial BW = 20.0 ± 1.31 kg) surgically fitted with T-cannulas at the distal ileum were assigned to 3 diets in a randomized complete block design with BW as a blocking factor. Two diets were prepared to contain DY or SBM as the sole source of nitrogen, and a nitrogen-free diet was prepared to determine the basal ileal endogenous losses of AA. The SID of AA, except for Gly and Pro, in SBM were greater (P &lt; 0.05) than in DY. The SID of indispensable AA in DY ranged from 64.7% for Thr to 86.1% for Arg, whereas those in SBM ranged from 84.8% for Thr to 92.3% for Arg. In conclusion, energy values in DY was comparable with SBM, but the SID of most AA in DY were less than in SBM.

Feeding trials involving a total of 78 Holstein steers and utilizing barley diets were conducted to determine the effects of vitamin E and trace minerals, hay, diethylstilbestrol, and physical form of the barley on rate of gain, feed efficiency and carcass characteristics.In the first trial, a basal diet containing 13.2% crude protein was used. Inclusion of a vitamin E, manganese, zinc, copper and sulfur supplement, 10% hay, or urea in the pelleted diets, or implantation with 9 mg of diethylstilbestrol at the initial weight of 92 kg did not improve rate of gain or dressing percent (P < 0.05). The inclusion of 10% hay reduced feed efficiency (P < 0.05).In the second trial in which dry-rolled, steam-rolled, dry-rolled and pelleted, and steam-rolled and pelleted barley diets were fed, the dry-rolled diet gave slower gains than the diets containing steam-rolled barley or steam-rolled, pelleted barley (P < 0.05). Implanting steers fed the steam-rolled, pelleted diet with 24 mg of diethylstilbestrol at 240 kg liveweight increased rate of gain over other treatments (P < 0.05). Treatments did not affect feed efficiency. Dressing percent was increased in steers fed steam-rolled barley in comparison with those fed dry-rolled barley.

Abstract The objectives were to determine the digestible energy and standardized ileal digestibility of amino acids (AA; Exp. 1) and to determine growth performance (Exp. 2) of 2 sources of dietary spray-dried plasma protein (SDPP) in nursery pigs. In Exp. 1, twelve nursery barrows (9.8 ± 0.9 kg) were assigned to a quadruplicated 3 × 2 Latin square design with 3 diets and 2 periods. Each period consisted of 5 days of adaptation, 2 days of fecal sampling, and 2 days of ileal collection. A basal diet was composed of corn, soybean meal, whey, and sucrose as the sole energy and AA sources. Experimental diets were prepared by replacing 15% of the energy and AA sources in the basal diet with SDPP 1 (manufactured in the USA; 78.2% crude protein and 4,862 kcal gross energy/kg as-is) or SDPP 2 (manufactured in Korea; 74.3% crude protein and 4,636 kcal gross energy/kg as-is). Spray-dried plasma protein 1 had greater digestible energy (P &lt; 0.05), but less (P &lt; 0.05) standardized ileal digestibility of Lys, Met, Trp, and Thr compared with SDPP 2. In Exp. 2, eighty-four nursery pigs (7.9 ± 0.7 kg) were allotted to 3 dietary treatments in a randomized complete block design with 7 replicate pens and 4 pigs per pen. Three corn-soybean meal-whey-based diets contained fish meal (6% and 3.5% for d 0 to 14 and d 14 to 28, respectively), SDPP 1 (4.5% and 2.7%), or SDPP 2 (5.0% and 3.0%) to maintain same energy and nutrient concentrations. During d 0 to 14 and overall period, pigs fed the diets containing SDPP gained more weight (P &lt; 0.05) than those fed the fish meal diet with no difference between 2 SDPP sources. In conclusion, SDPP 1 contains greater digestible energy but less AA digestibility compared with SDPP 2. Growth-promoting effects of both SDPP sources in nursery diets have been clearly demonstrated in this work.

Abstract An experiment was conducted on 240 one-day old male (Ross308) chicken to the effect of substitution of dried mealworm (Tenebrio molitor) with soybean meal on growth performance and carcass characteristics broiler chicks. Chicks fed in a completely randomized design with 4 replicate cages (12 birds per cage). Five dietary treatments used: 1- Control treatment: Basal diet based on corn-soybean meal without adding dried mealworm, 2- Replacement of 5% dried mealworm with soybean meal in the base diet, 3- Replacement of 10% dried mealworm with soybean meal in the base diet, 4- Replacement of 15% dried mealworm with soybean meal in the base diet and 5- Replacement of 20% dried mealworm with soybean meal in the base diet. The results of the experiment showed that 3rd and 4th treatments with a substitution of 10 and 15 percent showed a higher mean weight gain and a daily gain, but their feed intake was lower comparing other treatments, and finally, the feed conversion ratio showed a significant decrease with respect to control treatment using these replacement levels. At 21 and 42 days of age, carcass yield and relative weight of the breasts showed significant increases in treatments 3 and 4, and other characteristics of chicken carcasses were not affected by the test treatments. The experiment showed that replacing soybean meal with 10% and 15% worm powder significantly improved the performance of broiler chickens, but no significant difference was found between the two levels.
