The aim of the research was to improve the relative weight, relative length and dietary of the broilers’ small intestine (duodenum, jejunum, ileum) with the slight squeeze of the lime as acidifier. The research was conducted according to completely randomized design with 3 treatments and 6 replications (each experimental unit consisted of 5-6 broilers). Treatments were T0 (normal), T1 (5mL lime + 1000mL water), and T2 (10mL + 1000 mL water). Relative weight and relative length of the small intestine were not affected by the addiction of the lime, either dietary was not significantly affected by the addiction of the lime on the water as acidifier. The lime could not improve the dietary of the broiler. Keywords: Broiler, Lime, Acidifier, Small Intestine, Dietary.

The aim of this study was to evaluate the effects of different levels of bee pollen in the diet of growing Japanese quails on productive performance, relative weight of the gastrointestinal organs and length of small and large intestines. A total of 650 one-day-old female Japanese quails were distributed in a completely randomized design with five treatments according to the dietary levels of bee pollen (0.0, 0.4, 0.8, 1.2, and 1.6%), five replicates, and 26 birds per experimental unit. At the end of the experimental period (35 days of age), the performance and relative weight of the gastrointestinal organs and length of small and large intestines were evaluated. The dietary inclusion of bee pollen did not influence (P > 0.05) performance, relative weight of proventriculus, gizzard, pancreas, liver, and large intestine, as well as the length of small and large intestines. However, a linear reduction (P < 0.05) was observed in the relative weight of small intestine as dietary bee pollen levels increased. The inclusion of bee pollen from 0.4 to 1.6% in the diet of growing Japanese quails did neither improve productive performance nor alter the biometry of digestive organs.

An experiment was conducted to investigate the development of the digestive system in slow-growing broilers of different strains. The experiment involved a total of 544 one-day-old chicks, 136 of each of four genotypes, namely, Label Rouge Pesadão, Label Rouge Pescoço Pelado, Carijó and Carijó Pescoço Pelado. The birds were distributed in a completely randomized design with four treatments (genotypes) and eight replicates of 17 animals each. Live weight, digestive tract development and intestinal histomorphometric measurements were evaluated at different ages. Significant differences (p < 0.05) were observed between the strains for live weight, relative weight and length of digestive tract organs and intestinal histomorphometric measurements at one, seven and 28 days of age. The Carijó strain showed greater weight and development of digestive organs than the Carijó Pescoço Pelado strain. There was a difference (p < 0.05) for histomorphometric measurements of the small intestine between the strains at the evaluated ages. The Carijó Pescoço Pelado and Label Rouge Pescoço Pelado strains showed higher villi and higher villus:crypt ratios in the duodenum, jejunum and ileum. The slow-growing strains differ in performance regarding the relative weights and lengths of digestive tract organs and intestinal histomorphometric measurements.

The study aimed to examine the effect of using pollard in rations on the growth of proventricular, ventricular, duodenal, jejunal and ileal organs in 7-week-old broiler chickens. The research material used 200 broiler chickens aged 7 weeks with an average weight of 859 ± 59 g with each experimental unit consisting of 8 - 9 tails. The design used was a completely randomized design with 5 treatments and 3 replications. Treatment is given (T0 = Comersial feeds, T1 = Feed with pollard without processing, T2 = Feed with pollard treated physically, T3 = Feed with pollard treated physically and biologically, and T4 = Feed with pollard treated physically and biology 60%) and 3 replications. Based on the results of the study it can be concluded that the administration of pollard treated physically and biologically has not been able to increase all the relative weights of the digestive organs of broiler chickens aged 7 weeks. In the proventriculus organ, the treatment can increase the relative weight of broiler digestive organs, but the relative weight of the proventriculus produced is still relatively normal. Measurement of broiler chicken organ weight needs to be done per week to determine the rate of increase in the relative weight of the optimal digestive organs, so that the maximum data on the growth of broiler organs are obtained optimally

Abstract Piglets experience a decline in body temperature immediately after birth, and both drying and warming piglets at birth reduces this. However, these interventions may have less effective at higher farrowing room temperatures. This study was carried out at a commercial facility to compare the effect of drying and/or warming piglets at birth on postnatal rectal temperature (RT) under relatively warm farrowing room temperatures (26.6 ± 2.09°C). Forty-five sows/litters were used in a completely randomized design to compare three Intervention Treatments (applied at birth): Control (no treatment); Warming (piglets placed in a plastic box under a heat lamp for 30 min); Drying+Warming (piglets dried with desiccant and warmed as above). Temperatures in the warming boxes over the study period averaged 37.7 ± 2.75°C. At birth, piglets were weighed; RT temperature was measured at 0, 10, 20, 30, 45, 60, 120, and 1440 min after birth. Blood samples were collected at 24 h after birth from a subsample of one piglet from each birth weight quartile within each litter to measure plasma immunocrit concentration. Data were analyzed using PROC MIXED of SAS with litter as the experimental unit; and piglet a subsample of litter. The model for analysis of piglet rectal temperature included fixed effects of treatment, measurement time (repeated measure), the interaction, and the random effect of sow. Compared to the Control, piglet RT were higher (P ≤ 0.05) for the Warming treatment between 10 and 60 min, and higher (P ≤ 0.05) for the Drying+Warming treatment between 10 and 120 min after birth. Rectal temperatures were higher (P ≤ 0.05) for the Drying+Warming than the Warming treatment between 20 and 120 min. Responses to drying and/or warming were greater for low birth weight piglets (&lt; 1.0 kg) than heavier littermates, but were generally less than observed in previous experiments with similar treatments carried out under cooler temperatures. Piglet immunocrit values were lower (P ≤ 0.05) for the Drying+Warming treatment compared to the other treatments, which were similar (P &gt; 0.05). Immunocrit values tended (P = 0.10) to be lower for light (&lt; 1.0 kg) compared to heavier birth weight piglets. In conclusion, drying and warming piglets at birth was more effective for reducing piglet RT decline after birth than warming alone, though the effect was less than observed in previous studies carried out under cooler farrowing room temperatures.

Two experiments were carried out to determine the bioavailability of phosphorus in two spray-dried yeasts - sugarcane yeast (SCY), and sugarcane yeast + brewer's yeast (SCBY) - in starting pigs, by comparing different methods (Apparent Digestibility Coefficient of Phosphorus - ADCP; True Digestibility Coefficient of Phosphorus - TDCP; slope ratio; and standard curve). In experiment I, a digestibility assay were carried out using 30 cross breed pig with initial weigh of 22.69 ± 4.24kg, allotted in a completely randomized design. The mean ADCP and TDCP values were 62.68 and 64.15% for SCY and 77.01 and 79.33% for SCBY. ADCP and TDCP for SCBY were higher (P<0.05) than the values for SCY. In Experiment II, a growth test was conducted, 56 crossbred piglets, were utilized, with initial live weight of 15.11 ± 3.43kg, allotted in a completely randomized design, with seven treatments, four replications, and two pigs per experimental unit. The treatments consisted of a basal diet without supplementation with P and the same diet including supplementation with two levels of P (0.053% and 0.105%) from dicalcium phosphate, SCY and SCBY. The relative bioavailability mean value of 57.23% for SCY and 91.96% for SCBY, corresponding to 0.30% and 0.40% of available phosphorus, respectively.

<p>The objective of this study was to evaluate the effect of different nutritional plans on the body temperature and organ biometrics in male and female broilers, of two ages. Here, 1,700 birds were used (850 males and 850 females) in a completely randomized design composed of five treatments (- 3%, - 1.5%, reference, + 1.5% and + 3%), with 10 repetitions, totaling 50 experimental units; the reference treatment based on nutritional and energy levels indicated in previous studies was calculated from this. At 35 and 42 d, the temperatures of the wing, head, shin, back, and cloaca in males and females were measured separately, and the average surface and body temperature were calculated. At 42 d, relative weights of the gizzard, liver, heart, and small intestine were calculated. The temperatures of the wings, back, and cloaca, and consequently the average surface temperature and body temperatures, were not affected by nutritional plans. Effects of increasing the nutritional and energy levels were observed on liver weights, the gizzard, and the small intestine. We conclude that the nutritional plans did not affect body temperature. Males had higher body temperatures than females. Body temperature increased with increase in age, and the increase in the nutritional plans increased liver weight and reduced the gizzard weights.</p>

The objective of this work was to evaluate the productive performance of broccoli under different top-dressing organic fertilizations. The experiment was conducted under protected cultivation, in a completely randomized design with four replications, with two plants per experimental unit. Broccoli seedlings were produced in a commercial substrate in styrofoam trays. The seedlings were transplanted to plastic pots containing 10.0 L of substrate made up of subsoil and organic compost at the ratio of 3:1 (v/v), respectively, which is equivalent to about 20.0 t ha-1 of organic compost at planting. After seedling establishment, the top-dressing fertilization treatments were applied: gliricidia biomass associated or not with liquid biofertilizer of cattle manure to the soil and bokashi. Two control treatments were established: one with mineral fertilization recommended for the crop and the other without top-dressing fertilization. The broccoli production was evaluated (commercial standard). Plants that received mineral fertilizer were more productive, however, they were not significantly different (p>0.05), by Dunnet test, from the plants fertilized with 2.5 t ha-1 gliricidiabiomass (dry mass) associated with liquid biofertilizer (2.0 L m-2) applied to soil. Top-dressing fertilizations with only gliricidia, at 2.5 and 5.0 t ha-1 of biomass (dry mass), resulted in no significant increase in production of broccoli inflorescence. The use of bokashi in addition to gliricidia biomass and liquid biofertilizer reduced the efficiency of the fertilization compared with plants that received only gliricidia and liquid biofertilizer.

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.

 A research was conducted to increase the virulence of Beauvaria bassiana to the rice bug, L.  acuta, by adding four different substances (materials) to the rice media to grow the fungus. The research was conducted from April to August 2011 at Polinela Laboratory, Bandar Lampung.  To do this a set of experimental unit consisting of five treatments and five replications were arranged in completely randomized design. The  four treatments were media made up of rice (rice based media) each given or added with four different materials such as rice skin powder, corn sugar, grasshopper powder and chitosan powder. The result showed that B. bassiana grown on rice media added with grasshopper powder or rice skin powder were able of causing mortality to the L. acuta as high as 78% and 71%, respectively, meaning that both mortalities were much higher than that of other replication. The virulence values of Beauveria bassiana  grown on those both powder were also higher than that of three others.

Abstract Two experiments were conducted to test the hypotheses that pentoses absorbed from the small intestine of pigs reduce energy utilization and that pentoses that reach the hindgut are fermented. In Exp. 1, 24 barrows (9.95 ± 0.51 kg) with a T-cannula in the distal ileum were allotted to a completely randomized design with 3 diets that contained 15% glucose, 15% xylose, or 15% arabinose. Ileal digesta, feces, and urine were collected from all pigs. Data were analyzed via ANOVA using the Proc Mixed Procedure of SAS. No differences among diets were observed for apparent total tract digestibility of GE or for DE, but ME in xylose and arabinose diets was reduced (P < 0.01) compared with the glucose diet (Table 1) indicating that xylose and arabinose that are absorbed from the small intestine are excreted in the urine. In Exp. 2, 21 barrows (18.02 ± 1.1 kg) were allotted to a completely randomized design with 3 treatments and 7 pigs per treatment. A diet based on corn starch, casein, and 15% glucose was fed for 11 d. On d 4 through 11, saline, xylose, or arabinose (3% of the daily feed) was infused into the cecum of pigs via an ileal cannula, and feces and urine were collected. Data were analyzed as in Exp. 1. Infused xylose or arabinose was not detected in feces of the pigs infused with pentoses indicating that pentoses are fully fermented in the hindgut (Table 1). In conclusion, dietary free pentoses are absorbed prior to the end of the small intestine, but partially excreted in the urine, and therefore may reduce energy utilization. If pentoses are liberated in the hindgut, they may contribute to the energy status of the pig by being fermented with a subsequent absorption of short chained fatty acids.
