Forty-nine male calves were allotted in a randomized design, initially seven replicates per treatment at the end of the experiment were slaughtered four animals per treatment. Treatments CONT: control diet; FBC120: Dicalcium Phosphate 120:1 ratio P: F; MBC60: Monodicalcium phosphate 60:1 ratio P:F; FBC30: Dicalcium Phosphate 30:1 ratio P:F; SFT30: Super triple phosphate 30:1 ratio P:F; FBC10: Dicalcium Phosphate 10:1 ratio P:F; CAR10: concentrated ratio of 10:1 rock Q:F. Phosphates less elaborate showed higher amounts of heavy metals. In bones, iron, aluminum and lead were higher in FBC10 diet, the copper content was higher in animals fed the diet MBC60. Magnesium in liver was higher in animals fed diet FBC30, aluminum was higher for treatments SFT30 and FBC10, FBC120 and the cadmium and lead levels were higher in animals that received STF30. Treatments did not affect phosphorus and fluorine in muscle and heart, being that chromium was higher in the muscle of animals fed diets CAR10 and STF30 while cadmium in heart was greater in diet CAR10. Kidney phosphorus was higher in the animals fed the diet CAR10 and lower dietary FBC10, while aluminum was higher in the animals fed with the diet FBC10 and lower dietary FBC120 and levels of chromium and lead were higher in animals CAR10 diet and lowest in diet MBC60. Alternative sources of phosphorus and low ratios P:F increased the deposition of minerals in bones and liver, and this mineral deposition was lower in the muscles.

<p>Forty-nine male calves were allotted in a randomized design, being that initially were performed seven replicates per treatment. At the end of the experiment were slaughtered four animals per treatment. The treatments were designed as following: CONT: control diet; DC120: Dicalcium Phosphate 120:1 ratio P: F; MDCP60: Monodicalcium Phosphate 60:1 ratio P: F; DC30: Dicalcium Phosphate 30:1 ratio P: F; TSP30: Triple Superphosphate 30:1 ratio P: F; DC10: Dicalcium Phosphate 10:1 ratio P: F; PRC10: phosphate rock concentrate of 10:1 of relation P: F. Alkaline phosphatase (ALP) of animals who consumed PRC10 diet was greater than the ALP of animals that consumed TSP30, DC10 and DC120. This result was obtained with animals with 650 days of confinement. The ALP of the animals that consumed PRC10 was greater at 866 days than in the animals consuming TSP30 and DC120 diets. The ash content was greater in the DC10 diet and the diets CAR10 and DC120 achieved the lowest value. The fluorine content in bone was higher in diet DC10, while the diets DC120, PRC10 and MDCP60 obtained the lower values. The area of Haversian canals and the relation Havers/Osteon area were higher in the diet DC30 and the lowest value was encountered in DC10. The mottled teeth were more intensely observed in the treatments DC10 and PRC10. It was concluded that high fluorine content in the diet increases the deposition of fluorine in bones, which negatively affects in the histological parameters of teeth and bones of beef cattle.</p>

Abstract Yeast cell wall products are common functional ingredients capable of “priming” the immune system, specifically in reference to vaccine efficacy. Twenty-four adult, female Beagles were used in a completely randomized design. Three retorted diets were used: control diet (CON), CON plus β-glucan top-dressed daily upon time of feeding (C+B), and CON plus retorted β-glucan included in diet formulation (BG). Following a 7 d adaptation to CON, dogs were fed their respective treatment diets for 42 d and were challenged with an oral Bordetella bronchiseptica vaccine on d 14 with blood collections on d 0, 21, 28, and 42. The objectives of the present study were 1) to evaluate the effects of dietary inclusion of a yeast β-1,3/1,6 glucan (150 ppm) on apparent total tract digestibility (ATTD) of macronutrients, fecal microbiota, and peripheral blood mononuclear cells (PBMC; T-cells, B-cells, and monocytes) of adult dogs and, 2) to test the effects of retorting on the efficacy of these β-glucans. All diets were well-accepted by all dogs. ATTD of both dry matter and crude protein were greater (P &lt; 0.05) for BG than CON and with greater (P &lt; 0.05) energy digestibility for BG than both B+G and CON. Additionally, fecal short-chain and branched-chain fatty acids, ammonia, indole and phenol concentrations did not differ among treatments. No significant treatment by time interactions among treatment groups were observed for any analyzed PBMC. These data suggest that a 150 ppm inclusion of this yeast-derived β-glucan had no detrimental effects on ATTD, fecal characteristics and metabolites, nor any analyzed PBMC; however, due to the absence of differences in immune parameters among treatments, the effect of retorting on the efficacy of this product cannot confidently be assessed with these findings. Higher doses of yeast-derived β-glucan might be needed to elicit an immunological modulation in healthy adult dogs.

Abstract Red osier dogwood (ROD) is a native shrub plant rich in phenolic compounds with antimicrobial properties. The objective of this study was to evaluate the effects of substituting barley silage with either raw ROD or ROD extract (RODE) in high-grain (HG) diet under a low media pH (5.8) on gas production (GP), dry matter (DM) disappearance (DMD) and fermentation characteristics in batch cultures. The study was a completely randomized design with 4 treatments: 1) control diet (10% barley silage and 90% barley concentrate, DM basis), control diet supplemented with 2) monensin (30 mg/kg diet DM; positive control), 3) substitution of 3% ROD or 4) 3% RODE for an equal portion of silage. Inoculum was obtained from 2 ruminally fistulated beef heifers offered the HG diet. Substrate ground (1 mm) was incubated for 24 h and the experiment repeated twice. The GP did not differ among treatments (147 ml/g DM), but the DMD differed (P &lt; 0.02) at highest for control (69.4%), lowest for ROD (58.4%) and intermediate for other treatments (64.1%). Total volatile fatty acid (VFA) concentration (mM) tended (P&lt; 0.08) to be lower with ROD (80.5) and monensin (80.1) than control (83.9). Acetate proportion was greater (P = 0.02) with ROD (46.2%) and RODE (46.9%) than control (42.4%) and monensin (42.3%). However, the propionate proportion was greater (P = 0.05) with monensin (32.1%) than other treatments (averaged 30.1%). Consequently, acetate to propionate ratio (A:P) of ROD (1.52) and RODE (1.56) was higher than monensin (1.32; P &lt; 0.01) and control (1.44; P &lt; 0.08). Differences in variables measured between ROD and RODE were minimal. These results indicated that the decreased DMD along with increased A:P with addition of ROD or RODE suggests that both ROD and RODE may be beneficial to HG fed cattle for reducing risk of rumen acidosis without negatively impacting fibre digestion.

This work aimed to determine the nutrient intake and quantitative aspects of sheep carcass from three different genetic groups. Eighteen animals with initial average body weight of 20.1kg were used in a completely randomized design, in a factorial 3x2 scheme (three different crossbreeds - 6 F1Dorper x non defined breed, 6 F1Somalis x non defined breed and 6 F1Santa Inês x non defined breed versus two diets). The diets fed to the animals were formulated with or without cashew nuts. The inclusion of cashew nut meal in the diet influenced nutrient intake. Differences of intake among the animal groups were observed as higher intake for F1Dorper x non defined breed (NDB), followed by F1Somalis x NDB and for F1Santa Inês x NDB. However, the control diet produced no difference among these genotypes. The average daily gain was lower for both crossbreeds when cashew nut meal was added in the diets. The evaluated crossbreeds and diets did not affect the feed:gain ratio. The carcasses analyses showed that the inclusion of cashew nut meal in the diets reduced the cold carcass weight and the rib weight. The addition of cashew nut meal in the diets for lambs reduces food intake and carcass yield. The crossbreed F1Dorper x NDB presented the higher rate of average daily gain.

The objective of this study is to evaluate the influence of five feed restriction programs (FRP) on broiler performance and carcass yield. 425 Cobb 500® broilers were distributed in a completely randomized design with five FRPs and five replicates with 17 broilers. The FRPs were: Program 1 (P1): consumption ad libitum (AL) of control diet from 14 to 42 days; P2: quantitative restriction (QTR) of 10% of AL consumption from 14 to 28 days and AL consumption from 29 to 42 days; P3: AL consumption from 14 to 28 days and QTR from 29 to 42 days; P4: qualitative restriction (QLR) of 10% of the level of crude protein and essential amino acids from 14 to 28 days and AL consumption from 29 to 42 days; and P5: AL consumption from 14 to 28 days and QLR from 29 to 42 days. The broilers of the AL treatment gained more weight (p≤0.01), but had a similar FCR (P>0.05) compared to broilers submitted to QTR from 29 to 42 days. In addition, broilers fed QTR from 14 to 28 days presented a lower FI and a better FCR (p≤0.01) in relation to broilers fed QLR of 14 to 28 (P4) and 29 to 42 days (P5). The broilers fed QTR of 14 to 28 days diet presented a similar FCR as broilers fed AL. The 10% reduction in AL consumption of 14 to 28 d is a viable economical alternative to feed broilers up to 42 days of age.

Performance Results

Two experiments were carried out to determine the nutritional value and to evaluate the performance and carcass traits in the growing-finishing pigs fed on two types of semipurified glycerin, which were made from vegetable oil (SPGV) and mixed of animal + vegetable oil (SPGM). In the digestibility trial (experiment I) 32 crossbreed barrows were used with initial body weight of 45.08 ± 4.11kg. It were used three levels of inclusion (6, 12 e 18%) of semipurified glycerin (SPGV and SPGM) in the basal diet. The metabolizable energy (ME) value of glycerin were estimated by regression of ME (kcal/kg) intake associated with glycerin vs. glycerin intake (kg). The values of ME (kcal/kg) obtained were: 2,731 for SPGV and 2,210 for SPGM. In experiment II, 72 pigs (30.08 ± 1.65 to 60.58 ± 3.57) in growing and (60.83 ± 2.63 to 93.79 ± 5.72) in finishing phase, were allotted in a completely randomized design in a 2 x 4 + 1 factorial scheme, with two types of semipurified glycerin (SPGV and SPGA), four inclusion levels (4; 8; 12 and 16%), eight experimental unit and a control diet containing no glycerin (0%). All pigs were slaughtered to evaluate the carcass traits. The performance results suggest that it is feasible to use up to 16% of both semipurified glycerins on growing and finishing pigs feeding, without impairing performance and carcass traits.

This studywas carried out to determine the utilization and the optimumlevel of offer of bitter leaf (Vernonia amygdalina) meal (BLM) by West African Dwarf (WAD) goats. In a 20-week trial, twenty four WAD goats of both sexes, 5-7 months old, were randomly allotted to four treatments of graded levels of BLM(0% BLM(Control diet), 15% BLM, 30% BLMand 45% BLMdiets) in a completely randomized design to determine the utilization of bitter leafmeal as feed for goats. The dietswere used as supplements to a basal ration of Panicummaximum. Two digestibility trials were carried out. The digestible ether extract intake and digestible organic matter of goats on 0% BLM were significantly (P<0.05) higher than the values obtained for goats on bitter leaf meal diets. The average daily weight gain (g/day) for goats on 0% BML was significantly (P<0.05) higher than that of others. There were significant (P<0.05) differences in the percentage mortality of the goats fed experimental diets. The percentagemortality of goats on 30% and 45%BLMwere significantly (p<0.05) higher than that of others. It is concluded that bitter leafmeal can be included in the diets of (WAD) goats up to15%without any deleterious effect.
