title: Addition of chlorogenic acid and caffeine during the processing of cooled boar semen

description: ABSTRACT A study was conducted to evaluate the effect of chlorogenic acid (ChA) added pre-cooling and its combination with caffeine added during warming on cooled-stored boar semen parameters. Ten ejaculates were diluted in commercial extender with or without 4.5mg/ml ChA and stored at 15°C. After 0, 24 and 72 hours of storage, aliquots of these doses were taken and incubated at 37°C in the presence or absence of 8.0mM caffeine. Semen quality was evaluated after 10 and 120 minutes of incubation. The ChA increased (P &lt;0.01) the sperm motility, viability, acrosomal integrity and the percentage of spermatozoa with high mitochondrial activity (PMHA), however, decreased (P &lt;0.01) the malondialdehyde (MDA) concentration. Caffeine increased (P&lt;0.05) the sperm motility, viability, PMHA and the MDA concentration and reduced (P &lt;0.05) the acrosome integrity. When associated (ChA+caffeine), there was an increase (P &lt;0.05) in sperm motility and viability, PMHA and acrosome integrity. The addition of ChA to the dilution medium improves the quality of the swine inseminating doses. The addition of caffeine during re-warming is only recommended when the semen is stored for prolonged periods (72h), and the inseminating dose should be used immediately after its addition.

title: Cutaneous ureterostomies in pigs: technical feasibility assessment

description: ABSTRACT Increased life expectancy of pets favors the occurrence of cancer, such as the urinary bladder ones. The aim of this study was to evaluate the feasibility of cutaneous ureterostomy technique in pigs after the total cystectomy compared to the technique of colonic ureterostomy, as well as detect and characterize possible intraoperative complications. For that, 20 pigs were used, divided into two groups. All patients underwent radical cystectomy and then the cutaneous or colonic ureterostomies. The technical feasibility was assessed during the procedures. The procedures compared were: the incision size, dieresis time, realization of urinary diversion and the synthesis time. Also, the estimated blood loss and the degree of difficulty in performing the preparation procedures of the ureters, ureteroanastomose site preparation and ureteroanastomose itself were compared. The results indicate that performing cutaneous ureterostomy was better than the colonic ureterostomy in relation to blood loss, incision size, and anastomosis performance. In contrast, ureterocolonostomy showed better results on the implementation of ureteral preparation. Thus, it was concluded that both techniques can be indicated as viable urinary diversions and the choice will depend on factors intrinsic to the surgeon and the patient.

title: Growth performance and carcass yield of broiler chickens in response to carbohydrases and its association with phytase

description: ABSTRACT An experiment was conducted to evaluate broiler chicken performance and carcass yield in response to carbohydrase supplementation (Xylanase and Betaglucanase; XB) and association of carbohydrase and phytase (PHY). A total of 1,920 day-old male broiler chicks (Cobb 500) were distributed in a completely randomized design with 8 treatments and 8 replicates each, allocated in 64 pens with 30 chicks each. The treatments were: Positive Control (PC); Negative Control (NC): reduced ME [-120kcal/kg (Starter) and -170kcal/kg (Finisher)]; NC + XB [50g/ton]; NC + XB [100g/ton]; NC + XB [150g/ton]; NC + XB [50g/ton] + PHY [100g/ton]; NC + XB [100g/ton] + PHY [100g/ton]; NC + XB [150g/ton] + PHY [100g/ton]. The inclusion of XB (150) and XB (50, 100, and 150) associated with phytase increased feed intake than positive control when considering the total rearing phase. The feed conversion ratio of all broilers fed diets with energy reduction were worse than positive control, even with the addition of enzymes, and did not differ between them. There was no significant effect of treatments on carcass parameters.

title: Enzyme complexes on metabolizable energy and nutrient digestibility of millet for broiler chickens

description: ABSTRACT The objective of this study was to evaluate the effect of enzymatic complexes on metabolizable energy and nutrient digestibility coefficient of millet for broilers chickens. 576 male chickens, were distributed in 36 cages with three treatments: T1 - millet composition without enzymatic complex; T2 - millet composition with enzymatic complex (ECS); and T3 - millet composition with enzymatic complex (ECV). The treatments were defined from six diets (3 reference diets and 3 test diets). The test diets were obtained from the substitution of 40% for reference diet by whole millet, and the enzyme addition consisted of two enzymatic complex, ECS constituted by phytase, protease, xylanase, β-glucanase, cellulase, amylase and pectinase enzymes, and ECV constituted by protease, cellulase and amylase enzymes. In the 11 to 20 days phase, a supplementation with the ECV reduced the AME, AMEn and CDPB values, a ECS supplementation improved the CDPB, and there was no significant effect for CDMS and CDEB. In the 21 to 30 days phase, there were less profit of the energy and nutrients with ECS and ECV supplements. In the 31 to 40 days phase as supplements reduced the values of AME, AMEn, and the ECV complex was effective in increasing the value of CDPB. The inclusion of ECS enzymatic complexes, (phytase, protease, xylanase, β-glucanase, cellulase, amylase and pectinase) and ECV (protease, cellulase and amylase), did not favor millet's energy utilization, however, favored the millet's protein digestibility coefficient on 11 to 20 and 31 to 40 periods.

title: Grazing criteria for perennial peanut (Arachis pintoi cv. Amarillo) consumed by sheep in rotational stocking

description: ABSTRACT The objective of work was to study the productive profile of perennial peanut in a rotational stocking environment under different criteria. The treatments corresponded to pre-grazing height of 14 and 18cm or 95% of light interception (LI) distributed in a completely randomized design. The studied variables were forage mass, percentage of structural components, forage mass and the structural components in the lower and upper canopy strata. The entrance criterion of 18cm in height, despite having higher forage mass, presented lower percentage of leaves and higher percentage of stems and forage losses. The criteria of 14cm and 95% light interception presented similar production between them and the highest rate of forage accumulation. In all criteria, in the upper strata of pasture a higher percentage of leaves were found. The criteria of 95% LI and 14cm in height presented the best productive performances. The entry criterion of 18cm presented a higher mass of pre-grazing forage with lower percentage of dead material, but with higher forage losses, resulting from senescent leaves. Due to changes in the structural components, as grazing cycles increase, the interception of 95% of the incident light by the perennial peanut occurs at lower heights.

title: Identification of a historic horse ecotype analyzing speech content in central Brazil

description: ABSTRACT This study represents a first attempt to rescue germplasm of a traditional domestic equine cited in early Iberian and South American literature as Curraleiro horse. As an effort to identify and possibly characterize this type of horse we accessed traditional knowledge in strategic rural areas. Most areas were configured by hinterland settlements founded by runaway slave communities from the sixteenth century. Twenty interviews were conducted and analyzed using classical Speech Content Analysis. As a result, five response categories were recognized: 1) Identification and location of Curraleiro horses; 2) Characterization of Curraleiro horses; 3) Historical aspects; 4) Curraleiro horse conservation prospects and 5) Sanitary and productive aspects of Curraleiro horse breeding. We concluded that although scarce, the Curraleiro horse, cited in literature, still exists and showed phenotypical features which allow fine discrimination from any officially recognized breed in Brazil. Our findings may open the door for the recognition of a genuine animal resource which could play a role in rural development for specific regions and traditional communities. Speech Content Analysis was effective for in loco identification and characterization of rare traditional livestock. Thus, we encourage the usage of this tool as an alternative to subsidize identification and genetic conservation programs worldwide.

title: Bioeconomic analysis of protein-energy supplementation periods in dry season for Nellore heifers in stockpiled pastures of Urochloa decumbens

description: ABSTRACT Protein-energy supplementation (SPE) is an adequate strategy for beef cattle during drought season of the year, although the wrong adoption might compromise its cost/benefit ratio. The aim of this study was to evaluate Nellore heifers’ performance under SPE periods and to draw economic analysis of production systems. The experiment was conducted under a completely randomized design, with two systems: 147 and 55 days of SPE (Systems 1 and 2), from 06/21/2016 to 11/15/2016, with 16 and 20 heifers to Systems 1 and 2, respectively. Performance data were analyzed by SAS® PROC MIXED and means compared by PDIFF (P&lt; 0.05). The weight means were similar between the production systems (P&gt; 0.05) at weighing of 06/21, 07/12, 08/02, 08/23 and 11/15/2016. The net present values were positive under annual discount rate of 4%, being financially viable. By presenting internal return rate higher than the minimum attractiveness rate, the systems were attractive for investment. Positive economic balance was obtained of R$ 25.26/animal to replace System 1 by 2. The reduction of 92 days in SPE provides similar performance between Nellore heifers and greater economic efficiency of the production system.

title: Adaptation period to diets with low or high fiber on digetibility and faecal characteristics in dogs

description: ABSTRACT This study aimed to evaluate three periods of adaptation, 5, 10 and 15 days, to diets with low or high fiber on digestibility and fecal characteristics. Two diets were used, one containing 0% (0% SH) and one containing 15% soybean hulls (15% SH). Diets were provided to 12 adult dogs. At the end of each period there was total collection of feces to evaluate the apparent digestibility coefficients (ADC), metabolizable energy (ME) and fecal characteristics. We also evaluated diet palatability. There was no effect of the adaptation period on digestibility of diets (P&gt; 0.05). The 15% SH diet reduced ADC of dry matter (DM) and ME, compared to the 0% SH diet (P&lt; 0.05). Fecal consistency of the dogs did not differ among diets and periods (P&gt; 0.05). There was a decrease in fecal pH and ammonia in dogs fed the diet with 15% SH (P&lt; 0.05) after 10 days of feeding (P&lt; 0.05). There was no difference in diet palatability (P&gt; 0.05). Diet adaptation longer than 5 days did not alter the digestibility and most fecal characteristics of dogs, except for fecal ammonia. The inclusion of 15% SH in diet reduces DM digestibility and fecal pH and ammonia in dogs.
