title: A by-product of pinto beans in diets for quail in the laying phase

description: ABSTRACT. The aim of this study was to evaluate levels of inclusion of pinto beans in diets for quail in the laying phase on their performance and egg quality. A total of 280 Japanese quail in the laying phase were distributed into five treatments in a completely randomized design with eight replicates and seven birds per plot. Treatments consisted of five levels (0, 2, 4, 6, and 8%) of inclusion of pinto beans in the diets, which remained isoenergetic and isoproteic. The experiment began with the quail at 70 days of age and lasted 63 days, with their performance assessed every 21 days and egg-quality parameters on the last two days of each cycle. The following parameters were evaluated: final weight, feed intake, egg-laying rate, feed conversion (per dozen eggs and per egg mass), egg weight, eggshell thickness, specific gravity, yolk color, and weights of shell, yolk, and albumen. No difference was detected between the bean inclusion levels for any of the performance and egg-quality traits assessed or the birds' final weight. In conclusion, up to 8% raw pinto beans may be added in diets for Japanese quail in the laying phase without compromising their performance or internal-external egg quality.

title: Digestible methionine levels for white-egg layer pullets from 7 to 12 weeks of age

description: ABSTRACT. An experiment was carried out to evaluate the requirement of digestible methionine for growing pullets at growth phase (7 to 12 weeks of age). A completely randomized design was distributed in five treatments, six replicates, and 15 pullets per experimental unit. 450 Dekalb White pullets from the 7th weeks of age, with an average initial weight of 313.14 ± 12.49 g were used. Dietary treatments consisted in five diets supplemented with DL-Methionine which resulted in five levels of digestible methionine (0.266, 0.294, 0.322, 0.350, and 0.378 %). Performance, serological blood, histopathology and histomorphometry data were evaluated. Quadratic responses were observed for final live weight (p &lt; 0.0143), weight gain (p &lt; 0.0073), feed conversion ratio (p &lt; 0.0058), glycogen deposition in the liver (p &lt; 0.0001), gamma-glutamyl transferase enzyme activity (p &lt; 0.0008), and villus height (p &lt; 0.0024) with digestible dMet levels. In conclusion, the use of 0.343 % dMet, corresponding to a dMet:dLys ratio 55, is recommended for white-egg pullets from 7 to 12 weeks of age.

title: Effect of using inoculant on elephant grass silage with additives

description: ABSTRACT. This study aimed to evaluate the use of inoculant on silage of elephant grass, wet brewery waste and buriti meal at different silo opening times. The experimental silage tested was composed of 50% elephant grass, 30% wet brewery waste, and 20% buriti meal. The experimental design was randomized block in a factorial arrangement (2 x 4), where the treatments consisted of the use or not of inoculant during silage processing, and four silo opening times (7, 14, 21, and 28 days). Data collected were firstly subjected to ANOVA and subsequent Tukey’s test. Results were considered significant at p ≤ 0.05. The use of inoculant in silage production provided more acidic pH (p &lt; 0.05) and higher (p &lt; 0.05) effluent losses. Longer silo opening times resulted in more alkaline pH (p &lt; 0.05) and higher (p &lt; 0.05) effluent losses. The use of inoculant in silage production and longer silo opening times provided higher (p &lt; 0.05) content of ash, crude protein, and fats, and lower (p &lt; 0.05) content of dry matter and fiber (neutral and acid detergent). However, there was no interaction between the factors evaluated in this study. It was concluded that the inoculant may be used in the production of elephant grass silages, wet brewery waste, and buriti meal, providing a more acidic pH, higher effluent losses, lower contents of dry matter and fiber, and higher nutritional content. As the opening time was extended up to 28 days, there was more alkaline pH, higher effluent losses, lower dry matter and fiber content, and higher nutritional content.

title: Production and quality of sunflower and Paiaguas palisadegrass silage in monocropped and intercropping in different forage systems

description: ABSTRACT. The objective of this study was to evaluate dry mass production, fermentative parameters and chemical and bromatological composition of sunflower silage and Paiaguas palisadegrass silage in monocropped and intercropping in different forage systems. The experimental design consisted of randomized blocks, with four replicates. The treatments consisted of silage forage systems: sunflower monocropped; Paiaguas palisadegrass monocropped; sunflower row-intercropped with Paiaguas palisadegrass; sunflower inter-row intercropped with Paiaguas palisadegrass; and sunflower oversown and intercropped with Paiaguas palisadegrass, totalizing 20 experimental silos. Sunflower and Paiaguas palisadegrass were harvested at 110 days after planting at 20 cm from the soil for silage, using brush cutter. The silos were opened after 53 days of fermentation. The rows and inter-row intercropped systems contributed to increase the mass production of the ensiled material. The monocropped sunflower silage had higher values of pH, ethereal extract and acid detergent fiber and lower values of titratable acidity and dry matter, crude protein, neutral detergent fiber and in vitro dry matter digestibility values. The silages of the sunflower intercropped with Paiaguas palisadegrass in forage systems of crop-livestock integration presented better fermentative and bromatological characteristics, guaranteeing an adequate fermentative process and nutritional quality. In this way, the intercropping of these two forages potentiates the production of silage for feeding of ruminants during the period of forage shortage.

title: Indicators of land use by cattle: associations among methods and role of environmental factors

description: ABSTRACT. The objectives of this study were to investigate the associations among direct and indirect indicators of land use by cattle and to understand the role of some environmental factors on the definition of these indicators. The study was carried out in two areas, Nature Reserve (63.6 ha) and Private Area (30.4 ha), with 53 Hereford animals in each area. Daytime observations of animals’ location were used as direct indicator of land use; while cattle track and dung pat distributions throughout the areas were used as indirect indicators. Environmental characteristics recorded were: terrain slope, prevalence of woody vegetation cover (forests, isolated tress and open grasslands), as well as the position of fences, water sources and salt blocks. Spatial correlations among the three indicators of land use were low (r &lt; 0.30). The environmental factors had lower predictive power of animals’ sightings distribution, followed by cattle tracks, and the highest predictive power occurred for dung pat distribution. We concluded that each one of the methods evaluated in this study addresses a different aspect of land use by cattle. The environmental factors assessed were useful to predict the dung pat distribution, but less valuable to predict the cattle tracks and animals’ sightings distributions.

title: Genetic analysis of fertility traits of Holstein dairy cattle in warm and temperate climate

description: ABSTRACT The edited data set for the estimation of heritability, genetic and phenotypic correlations of fertility traits contained up to 23,402 records from 10,894 cows calved between 2001 and 2015. Heritability estimates for success in first service (FS), gestation length (GL), number of inseminations (NI), insemination outcome (IO), calving interval (CI), calving birth weight (CBW) and days open (DO) were low and ranged between 0.016 (DO) and 0.123 (GL). Repeatability of fertility traits was estimated to vary from 0.021 (FS) to 0.411 (IO). The genetic correlations between DO × CI, DO × NI and CI × NI were positive and nearly perfect (0.98, 0.88 and 0.88, respectively), while those between DO × IO and CI × IO were negative (-0.98 and -1, respectively). Further, the phenotypic correlations between DO × CI, DO × NI, CI × NI, CBW × IO and SF × IO were 0.99, 0.83, 0.83, 0.99 and 1, respectively, while those between DO × IO, CI × IO, GL × IO and NI × IO were -0.99, -0.99, -0.99 and -1, respectively. Overall genetic parameters imply a good practical management in heat stress conditions will be essential for improving fertility efficiency.

title: Cuts of dairy-origin cattle fed mesquite pod meal in replacement of corn

description: ABSTRACT. This study was carried out in order to assess commercial front and rear cuts of dairy-origin cattle fed mesquite pod meal. Twenty-five non-castrated male bovines (Holstein-Zebu), distributed according to a completely randomized design, with five animals per treatment, were used. The feed contained about 121.2 and 544.98 g kg-1 of crude protein and total digestible nutrients, respectively, and was composed of tifton grass hay, cornmeal, soybean meal, mesquite pod meal and mineral salt. The right half carcass of each animal was separated between the 5th and 6th ribs, in front and rear quarters, from which commercial cuts were obtained. There was no effect (p &gt; 0.05) as to the replacement of corn for mesquite pod meal on the weights and yields of front cuts (shoulder, brisket, chuck, hump and flanks) and rear cuts (tenderloin, shank, knuckle, thin flank, flat, eye round, rump tail, top side, cap of rump, rump, cut of rump, striploin, cap of cube roll). Mesquite pod meal can substitute cornmeal in 100% in the concentrate without changes in weight and yield of the commercial front and rear cuts of male bovines of dairy origin.

title: Carcass yield and proximate composition of bullfrog (Lithobates catesbeianus)

description: ABSTRACT. This work evaluated five classes of weight of bullfrog (Lithobates catesbeianus) seeking to define the ideal slaughter weight for the species. We used 79 bullfrogs, distributed in a completely randomized design (class 1 &lt; 100 g (n = 10); class 2 from 101 to 150 g (n = 17); class 3 from 151 to 200 g (n = 24); class 4 from 201 to 250 g (n = 14); and class 5 &gt;251 g (n = 14)), which were euthanized, weighted and gutted. For the carcass yield, we weighed the clean torso, thighs, liver, skin and head. The clean torso was subjected to chemical composition analysis. The carcass yield was, on average, 49% with no difference between weight classes (p &gt; 0.05). The yield of posterior thighs was significantly higher for the lower weight class, which also presented higher percentage of paws (28.37 ± 0.63 and 9.33 ± 0.21, respectively) (p &lt; 0.05). The percentages of visceral fat and skin showed a progressive increase along with the weight of the animals; the class with individuals weighing 201-250 grams showed the higher values (p &lt; 0.05). The chemical composition indicated that individuals above 251 grams showed lower values of ether extract and higher values of crude protein (0.99 ± 0.14 and 15.80 ± 0.64, respectively) (p &lt; 0.05). So, it is recommended the slaughter of bullfrogs weighing more than 201 grams, because of better yield and meat quality.

title: Effects of supplementing broiler diets with a combination of fermented red ginseng marc powder and red-koji on thigh meat quality of broiler chick during storage

description: ABSTRACT We assessed the effects of supplementing broiler diets with a combination of fermented red ginseng marc powder and red-koji on thigh meat quality of broiler chick during storage. Broilers (n = 120) were randomly assigned to one of two groups: control or treatment with 1% fermented red ginseng marc combined with red-koji. There were four replicates per group, each comprising 15 birds (10 male and 5 female). Neither the dietary supplementation group nor the number of storage days had a significant (p &gt; 0.05) effect on meat pH. However, TBARS, a measure of lipid oxidation, was significantly affected (p &lt; 0.05) by both the number of storage days and the dietary supplementation, with reduced TBARS activity noted in the treatment group after 7 days of storage. There was no significant impact (p &gt; 0.05) on the lightness (L*) of meat in group after 1 and 7 day of storage (included T1 group), or redness (a*) of meat in group at 1 through 7 days of storage, whereas the yellowness (b*) of meat in both groups increased significantly (p &lt; 0.05) with an increase in storage duration. Our results suggest that supplementing broiler diets with fermented red ginseng marc combined red-koji powder does not affect meat color, even after storage. We conclude that dietary supplementation with 1% fermented red ginseng powder combined with red-koji can reduce lipid oxidation in broiler thigh meat after 7 days of storage.

title: Silage quality of Urochloa brizantha cultivars with levels of campo grande Stylosanthes

description: ABSTRACT The seasonality of forage production represents a limiting factor in the production of ruminants. The use of silages has been a solution for periods of low forage production, providing high quality food. This study was conducted to evaluate the fermentative characteristics and the chemical composition of silage of Urochloa brizantha cultivars with different levels of Campo Grande Stylosanthes. It was used a complete randomized block design with three replications in a 2 x 4 factorial design, being two cultivars of Urochloa brizantha (BRS Piata palisadegrass and BRS Paiaguas palisadegrass) and four levels of Campo Grande Stylosanthes (0, 10, 20 and 30%). Silages of Urochloa brizantha with Campo Grande Stylosanthes exhibit satisfactory quality, on the basis of the characteristics evaluated, with no significant difference between cultivars. The mixed silage of Campo Grande Stylosanthes with grasses at 30% has proven to be an interesting option, thus promoting adequate fermentation and maintaining the nutritional quality of silage.

title: Induced reproduction of dourado ( Salminus brasiliensis ): fertilization with sperm cryopreserved in ACP (r) -104

description: ABSTRACT. Experiments were conducted to improve the fertilization rate of cryopreserved semen of dourado, Salminus brasiliensis. The experiment tested two cryoprotectant solutions at different semen: cryoprotectant ratios (1:5, 1:15, 1:25 and 1:50). The standard solution for the species (mixture of dimethyl sulfoxide, glucose, egg yolk and distilled water) was compared to a 350 mOsm ACP(r)-104 solution, which is composed of powdered coconut water diluted in distilled water and methylglycol. Differences between the dilutions tested were significant only for ACP(r). The fertilization potential by using the standard solution at the lowest dilution (1:5) is equated when the sperm is diluted in ACP(r) at 1:25 or 1:50. These results show that the standard solution is the most suitable for the cryopreservation of dourado sperm, since the dilution did not alter the fertilization rate, requiring smaller storage space.

title: Effect of feeding canola meal to laying Japanese quails

description: This study evaluated the effect of different levels of canola meal in the diet to laying Japanese quails on productive performance, egg quality and economic viability. A total of 120 80-day-old Japanese quails (Coturnix coturnix japonica) with average weight 146.54 ± 12 g were evaluated during 84 days. Dietary treatments consisted of the replacement of soybean meal with canola meal at 0, 10, 20, 30, 40 or 50%. We evaluated economic viability, productive performance, internal and external quality of eggs. Data were analyzed by polynomial regression at 5%. Body weight decreased linearly as the level of canola meal increased (p = 0.0055). Egg weight (p = 0.0032) and diameter (p = 0.0398) showed a quadratic response, increasing up to 30% substitution with subsequent reduction. Yolk color increased linearly as the level of canola meal increased (p = 0.0039). Canola meal can substitute soybean meal up to 30% without impairing productive performance, egg quality and diet cost.

title: Determining a model to estimate leaf area in Pornunça (Manihot sp.) using morphometric measures

description: ABSTRACT. Pornunça is a species of the genus Manihot that has been cultivated as an option for animal feeding in the Brazilian semi-arid. Leaf area (LA) is important to determine forage plant growth, whose evaluation model has to meet the following characteristics: practicality, precision and low cost. The objective of this study was to set a model to determine the leaf area in Pornunça (Manihot sp.) from morphometric measurements of the leaf. The experimental design was in randomized blocks with three methods for determination of leaf area, and three blocks, with 144 replicates (leaves). For the determination of LA, the direct method (FAReal), treadmill leaf area meter (Li-Color 3100©) and linear dimensions were used. Data were subjected to regression analysis. There was a relationship between the actual leaf area (FAReal) for small, medium, large and total leaves, and the leaf area determined by the treadmill leaf area meter (FALi-Cor©) with a high coefficient of determination for linear fit. The Pornunça leaf area obtained by the Li-Cor3100© meter is approximately 10% lower compared to the FAReal method. The model that best fit the Ponunça leaf area estimation was the potential.

title: Nutritive value of pastures of Cynodon mixed with forage peanut in southwestern Paraná State

description: This study evaluated the nutritive value of pastures of Coastcross-1 and Tifton 85 mixed with increasing inclusion of forage peanut (0, 25, 50, 75% occupancy area), subjected to cuts, over two study years in Southwestern Paraná State. The experimental design was factorial (three factors) distributed in randomized block. The factors were cultivars (2), the occupancy area of forage peanut (4) and seasons of cuts (5), with three replications. It was evaluated the percentage of crude protein, neutral detergent fiber and in vitro digestibility of dry matter of leaf blades, stem + sheath of grasses and available forage mass of pastures. Values of crude protein ranged from 17.0 to 20.4% and from 16.8 to 19.3% for the forage mass available of Coastcross-1 and Tifton 85, respectively. Higher digestibility values were found at the beginning of evaluations. On average, the Coastcross-1 showed better nutritive value compared to Tifton 85, and, the inclusion of forage peanut increased crude protein content in leaf blades of grasses studied, in the second year after planted.

title: Aerobic stability in corn silage (Zea mays L.) ensiled with different microbial additives

description: ABSTRACT. This study aimed to assess different microbial additives, regarding the efficiency of aerobic stability in corn silages. The corn hybrid used for silages production was the DKB 310. The treatments consisted of: 1) control treatment without any microbial additive; 2) Treatment with LPPA composed of: Lactobacillus plantarum CCT 0580 3.1 x 1010 CFU g-1 and Propionibacterium acidipropionici CCT 4843 3.1 x 1010 CFU g-1; 3) Treatment with Inoculum, composed of Bacillus subtilis CCT 0089 3.0 x 109 CFU g-1, Lactobacillus plantarum CCT 0580 1.2 x 1010 CFU g-1 and Propionibacterium acidipropionici CCT 4843 1.5 x 1010 CFU g-1 and 4) Treatment LB, composed only of Lactobacillus buchneri CCT 3746 2.6 x 1010 CFU g-1. The experimental design was completely randomized with five replicates for each treatment. For the parameters evaluated daily, we used the split plot design, in which the different silages were assigned to the plots and the time of exposure to air was assigned to the subplots. There was no difference of additives on silage pH in any of the evaluation days. The control silage reached higher temperatures indicating greater vulnerability. All additives had no aerobic instability. Silages made with the use of microbial additives were effective in maintaining the aerobic stability.

title: Performance in preweaning pure and crossbred calves in the Mato Grosso do Sul Pantanal region, Aquidauana, Mato Grosso do Sul State, Brazil

description: ABSTRACT. Purebred and crossbred calves (n = 3,871) were selected that were born in the sub-region of the Pantanal of Aquidauana (Brazil), derived from Nellore, Brangus, Wagyu, and 1/2 Brangus + 1/2 Nellore cows, which were artificially inseminated by bulls of the Aberdeen Angus, Red Angus, Brangus, Nellore, and Wagyubreeds. Parameters such as weaning weight, daily gain from birth to weaning, and the number of days to gain 160 kg, were assessed inthese calves and phenotypic correlations between the traits were evaluated. Data were analyzed using two statistical models. The first model included sire breed effects, the genetic group of the cow, sex, year of birth (AN), birth season (EN), and the interaction AN * EN. The second model included the genetic group of the calf, sex, AN, EN, and the interaction AN * EN. The genetic group of the cow and calf and the interaction AN * EN did not significantly affect body weight (p &lt; 0.05). The average weaning weights of progeny were as follows: Aberdeen Angus bulls, 177.70 ± 3.28 kg; Red Angus, 180.31 ± 3.46 kg; Brangus, 181.48 ± 3.15 kg; Nellore, 175.43 ± 3.60 kg; and Wagyu, 173.16 ± 2.96 kg.
