title: Technological Advances in Cattle Welfare: An Analysis of Patent Families

description: ABSTRACT The research carried out intended to analyze the panorama of patents related to welfare in cattle. To this end, a search was carried out on the worldwide Questel Orbit patent registration database oriented toward the existence of terms associated with welfare in cattle in the documents of patent families. The investigation corresponded to the period from the beginning of the registrations in 1967 until August 2019. In this way, an initial portfolio was created of 272 registrations. Of these, 77 documents were related to cattle, with direct or indirect interventions in the optimization of the welfare. Data analysis took place in a quantitative way and through the classification of patent families in seven categories: nutrition, health, management, genetics, infrastructure/facilities, physiological and behavioral indicators, and traceability/certification. The largest number of patent families corresponded to the areas of rural facilities, animal nutrition, health, and new physiological and behavioral indicators, totaling 73%. The temporal distribution of these records shows that the interest of researchers in promoting technological innovations focused on well-being began in 1995, with expressiveness from 2013. It should also be noted that the largest registration of patent families comes from China (51%), followed by European countries, which account for 23%, and the United States (19%), while Brazil represents only 6% of the total documents. Despite the recent patent registrations related to cattle, there has been an increase in recent years, denoting the growth of efforts for technological innovation of this productive chain regarding animal welfare.

title: Effectiveness of flor-de-seda and pomegranate aqueous extracts on eggs of the Heterakoidea Superfamily isolated from naturally infected japanese quails

description: ABSTRACT The present study aimed to evaluate the in vitro anthelmintic efficacy of flor-de-seda (Calotropis procera S.W.) and pomegranate (Punica granatum L.) extracts on gastrointestinal nematode eggs of Japanese quails. Stool samples were collected from a herd of 5,000 adult birds raised on the floor at a commercial farm in the state of Ceará, Brazil. The samples were packed in plastic bags, kept refrigerated and transported for laboratory analysis. The eggs were placed in 2.5 ml of the suspension and 2.5 ml of flor-de-seda and pomegranate extracts in concentrations of 50; 25; 12.5; 6.25 and 3.12%. Readings were subsequently taken at 24, 48 and 72 hours. The aqueous pomegranate extract at 25 and 50% was more efficient on the larvae hatching. The flor-de-seda aqueous extract in both concentrations and evaluation periods showed similar action to that of the positive control treatment (Albendazole 10%). The pomegranate and flor-de-seda aqueous extracts have anthelmintic activity on the development of larvae in eggs of the Heterakoidea Superfamily and are therefore presented as an alternative to replace the drugs commonly used to control helminths in Japanese quails.

title: Production and composition of milk per Holstein and Jersey cow from two farms in northwest Rio Grande do Sul

description: ABSTRACT The aim of the present study was to monitor cow milk quality and composition in two farms in the Noroeste Rio-grandense mesoregion, located in the municipalities of Palmeira das Missões and Pinhal - RS. Both herds were mixed, with animals of the Holstein (70%) and Jersey (30%) breeds. The following overall parameters were evaluated: body condition score (BCS), udder dirtiness, and calving order, and the following milk composition factors were measured: total dry extract (TDE), defatted dry extract (DDE), milk lactose, fat, and protein contents, casein, milk urea nitrogen (MUN), and somatic cell count (SCC). Multivariate statistical analysis was performed, and four factors were identified representing combinations of the measured variables. The first factor comprised negative relationships between milk production and cow breed, milk fat content, and milk protein content. The second factor comprised the positive relationships between lactation days and body condition score and milk protein content. The third factor represented the negative relationships between milk lactose content and SCC score, calving order, and BCS. The fourth factor was composed of the positive relationship between delivery order and udder dirtiness. Cluster analysis revealed that individual cows could be categorized into three groups. Monitoring the breed, calving order, body condition score, lactation days, milk production, fat, protein, and lactose contents, somatic cell counts, and udder dirtiness in cows allows greater control of the herd, allowing potential shortcomings to be rectified quickly and economic losses to production to be minimized.

title: Effect of natural feed additives on meat quality and caecotrophic fatty acid profile of New Zealand rabbits

description: ABSTRACT The objectives of this research were to evaluate the effects of commercial probiotic and chitosan as food additives on the quality and meat composition of 36 New Zealand White rabbits (57 ± 8 days old and 1,648 ± 0.194 kg) and on the fatty acid profile of caecotrophs. The treatments were CT (diets without inclusion of additives), PRO (inclusion of 4 g / kg of commercial probiotic) and CHI (inclusion of 4 g / kg of chitosan). The additives increased triglycerides and decreased urea compared to the control group, as well as increased oleic and linoleic acids, Ʃ unsaturated, Ʃ monounsaturated and Ʃ polyunsaturated in caecotrophs. CHI animals showed a decrease in myristic and palmitic acids compared to PRO. CHI decreased the meat's crude protein and the meat's fat. In addition, there was a decrease in omega-3, omega-6 and the relationship unsaturated and saturated fatty acids for the CHI group and an increase in erucic acid and a decrease in the rate of hypocholesterolemic acids. As a conclusion, the data showed that the animals that ingested probiotic had better meat quality, for having better fatty acid profile and hypocholesterolemic index, compared to the treatment with chitosan. The additives improved the caecotrophs fatty acid profile.

title: Ruminal fermentation kinetics of by-products using the semi-automatic technique of in-vitro gas production

description: ABSTRACT The objective of this study was to develop a specific equation for the conversion of pressure values (psi) to volume (ml) for the Laboratory of Bromatology of the Federal University of Western Pará. To this end, the ruminal fermentation kinetics of regional feedstuffs were evaluated using the semi-automatic technique of in-vitro gas production. To set up the targeted equation, samples of ground corn, soybean meal, rice bran, Mombasa grass, cupuassu pie, cassava residues, and banana leaves were incubated and the pressure and volumes of the gases produced during the fermentation process were measured at predetermined times and related. These data on the volume of produced gases were used to determine, by applying the bi-compartmental logistic model, the ruminal fermentation kinetics parameters. The equation found for the laboratory was V = 0.3757P2 + 1.5972P + 0.2189. Ground corn and cassava residue showed a higher degradation rate of non-fibrous carbohydrates (0.120 and 0.163 %/h respectively) and higher final gas volume (228.91 and 273.17 ml/g of DM, respectively). As for the degradation rate of fibrous carbohydrates, ground corn (0.023 %/h), rice bran (0.023 %/h), and cassava residue (0.021 %/h) presented the highest degradation rate. Thus, a specific equation to be used at the Laboratory of Bromatology of the Federal University of Western Pará was identified, according to the method applied and the altitude of the premises. Ruminal fermentation kinetics of cassava residue and rice bran showed the same parameters as corn, which may suggest the possibility of replacing corn in the diet of ruminant animals.

title: Mineral supplementation of dairy heifers in Marandu-Grass pasture in spring and summer seasons

description: ABSTRACT Here in this study we assessed dairy heifers kept in tropical grasslands during spring and summer seasons to observe the effects of two supplementation strategies upon their performance. Sixteen dairy heifers (Holstein 5/8 x Gyr 3/4) with 135.25 kg of body mass were randomly assigned in two supplementation treatments (e.g., mineral salt and protein salt supplement) during spring and summer seasons, divided into two groups of eight animals that represented 4.29 animal unit ha. Initial and final fasted weights (i.e., feed and water withheld for 16h) were obtained before to start and at the end of each grazing cycle (28 days), and then the weight gain (kg animal-1) per grazing cycle was calculated by the difference between final and initial weights. There was no significant effect (P &lt;0.05) on the intake of dry matter, crude protein, ether extract, neutral detergent fiber, and dry matter digestibility, between treatments (P &lt;0.05). However, there was a significant effect (P &lt;0.05) between seasons; e.g., respective means of dry matter intake (kg day-1,% BW g / kg 0.75), intake of crude protein (g day-1 g / kg 0.75), ether extract (g day-1), neutral detergent fiber (g day-1 and% BW) were 3.95 and 2.88 kg, 2.54 and 1.65%, 89.27 and 59.56 g kg0.75, 429.89 and 298.43 g day-1, 9.72 and 6.18 g kg0.75, 118.79 and 84.07 g day-1, 2.90 and 2.05 kg day-1, 1.86 and 1.18%, for Spring and Summer seasons. Moreover, the dry matter intake (% BW and g kg 0.75 of DM) were higher (P &lt; 0.05) during the spring season (e.g., 2.53 vs 1.64 % BW; and 89.26 vs 59.56 g kg0.75 DM).

title: Etiology, symptoms and prevention of chalkbrood disease: a literature review

description: ABSTRACT The fungus Ascosphaera apis, responsible for causing the chalkbrood disease of honey bees, is widely present in temperate regions of the northern hemisphere, but has also spread to other regions of the world such as Brazil. Although it is not usually lethal for the colony, it can reduce its population, hampering its development. This study is a review on the disease that presents a broad overview of its development, identification methods as well as ways to control it. Research shows that chalkbrood is associated with several factors and is most frequently found in colonies of Apis bees during the spring, when there is excess humidity and sudden temperature changes in the hive. Other factors such as viral or bacterial infection, the presence of the ectoparasite Varroa destructor, pesticide poisoning and poor nutrition of nurse bees can also affect its incidence and severity. Field diagnosis is made based on the presence of hardened mummified brood in the pupal stage, of white or black color, in the cells and entrance. Affected cells show dead pupae covered with white mycelia, resembling cotton, or hardened, dry and brittle, resembling chalk pieces, which originated the name. To date, there are no efficient methods to reduce the damage caused by chalkbrood. Genetic selection of bees with higher hygienic behavior and disease resistance is recommended.

title: Substitution of limestone for eggshell powder in the diet of Japanese laying quails

description: ABSTRACT Were evaluated the effects of substituting limestone with quail eggshell powder on the zootechnical performance, egg quality, and economic efficiency of Japanese quails during peak egg production (11-20 weeks old). The experimental period was 63 days, divided into three 20-day periods. A completely randomized experimental design was used with five treatments (0, 25, 50, 75, and 100% substitution of limestone by eggshell powder), six repetitions, and seven birds per experimental unit, for a total of 210 quails. Feed intake, production of egg/bird/day, egg production per bird housed, marketable egg production, egg viability, feed conversion per egg mass, Seedor index, tibia calcium content, and percentage of calcium excreted were determined. The following variables for egg quality were analyzed: egg weight, specific weight, percentage of egg yolk, albumen and shell, and shell thickness. Economic efficiency was evaluated in fresh and industrialized eggs. Statistical analyses were performed using the SAS software, version 9.2 (2010). Substitution of limestone for eggshell powder had no significant effect on zootechnical performance, tibia calcium content, or egg quality. However, there were significant effects on the percentages of albumen and calcium excreted. The substitution of limestone by eggshell powder in quail feed resulted in higher economic efficiency indexes. These results indicate that the use of 100% eggshell powder in the feed of Japanese laying quails is viable.

title: Supplementation of growing bulls grazing Panicum maximum cv. Coloniao increases average daily gain and does not impact subsequent performance in feedlot phase

description: ABSTRACT To evaluate the influence of supplementation strategies on the average daily gain (ADG) of cattle in a rotational grazing system of Guinea grass (Panicum maximum cv. Coloniao) pastures during the rainy season. It was further evaluated the residual effects in the feedlot finishing phase. Seventy-five 8 month-old crossbred bull calves averaging 200.1 ± 2.5 kg of body weight (BW) were stratified and grouped in three into 25 blocks according to BW, and then randomly assigned to one of three supplementation treatments: control (no supplement), energy supplement [65 g crude protein (CP)/kg dry matter (DM)] or protein supplement (200 g CP/kg DM) both fed as 6 g/kg BW. All animals composed a single herd and were separated daily according to treatment groups for supplementation. After the grazing phase, all animals were moved to a feedlot and received the same diet up until slaughter. Guinea grass was subjected to rotational stocking with pre- and post-grazing heights of 76 and 43 cm, respectively. Energy and protein supplements provided similar ADG (P &gt; 0.05; 0.94 kg/day) which was greater than for non-supplemented animals during the grazing phase (P ≤ 0.05; 0.74 kg/day), but there was no difference in the subsequent feedlot phase (P &gt; 0.05; 1.45 kg/day). The protein supplement had no incremental effects over the energy supplement on ADG and carcass traits of growing crossbreed bulls during the grazing phase, indicating that either source could be used, and that an energy supplement would lead to more efficient nutrient use coming from the grass.

title: Bee pollen improves productivity of laying Japanese quails

description: SUMMARY This study aimed to evaluate the effects of bee pollen (BP) on the performance of laying Japanese quails and egg quality. A total of 60 quails were used in a completely randomized experimental design with four treatments (0%, 0.5%, 1%, and 1.5% BP inclusion in diets) and five replicates. At the end of the study, productive performance and egg quality were evaluated; 160 eggs were maintained at different temperatures based on a completely randomized design and factorial arrangement (4 × 2), with four BP levels (cited above) and two storage temperatures (room temperature and refrigeration) for 14 days, totaling eight treatments with four replicates. BP levels did not influence (P&gt; 0.05) feed conversion; however, daily feed intake, laying rate, egg mass, and weight and percentage of albumen increased. Yolk percentage decreased due to the augmentation of BP in diets. There was no effect (P&gt; 0.05) of interaction of storage temperature × BP levels on egg quality, except with regard to the Haugh unit. BP supplementation resulted in higher egg weight and index of yolk and albumen. Refrigerated eggs had better internal quality than normal eggs. BP inclusion in diets of Japanese quails improved bird performance and the quality of fresh and stored eggs.

title: Thermal stress alters the basal value of serum proteins in laying hens

description: ABSTRACT This study aimed to evaluate the effect of thermal stress on the physiological and metabolic parameters in laying hens and the microbiological quality of eggs. The experiment was performed with 50 Rhode Island Red hens in the initial laying phase, under standard diet, lodged in 20 m² stalls under controlled temperature, for 30 days. The laying hens were randomly divided into two groups: G1 - the control group, which contained 10 hens exposed to the temperature of 17 ºC; G2 - the treatment group, which contained 40 hens exposed to the temperature of 30 ºC. The physiological parameters evaluated were: cloacal temperature, body surface temperature, heart rate, respiratory rate, and weight. Biochemical tests included total protein, albumin, globulin, and glucose. The group subjected to thermal stress showed lower body weight, increased heart rate, a slight increase in the respiratory rate, and increase in body surface temperature when compared with the control group (P &lt; 0.05), although no significant differences were observed regarding cloacal temperature. As for the metabolic parameters, the treated group showed an increase in total proteins and globulins compared with the control group (P &lt; 0.05), while albumin remained at basal levels. Additionally, hypoglycemia was observed in the treated group. Samples from egg shells and yolk were subjected to the analyses for the detection of Salmonella spp. These microorganisms were not detected amongst the egg samples.

title: Intake, digestibility and recovery of grains from feces of steers fed different oilseeds

description: ABSTRACT Oilseed grains are used as a protein and energy source, increasing the energy density of the feed. The goal of the present study was to determine the nutritional profile of canola, crambe and soybean grains recovered from feces, and to evaluate the intake and digestibility of nutrients, rumen fermentation parameters of beef cattle receiving whole grains of oilseeds. Three steers, 350 ± 23.5 kg body weight were distributed in a not contemporary, 3 × 3 double Latin square, and fed oilseed grains. Inclusion of crambe grain reduced dry matter intake by 21.02%, with a higher digestibility coefficient for EE and NDF. The crude protein content of canola and crambe grains recovered were similar, but the EE content was higher for the crambe grain (26.46%). Soybean showed the lowest values of chemical composition for grains recovered from feces. The highest dry matter intake (7.86 kg/day), and the lowest NDF digestibility (0.203g/kg), were found for animals fed soybean. The inclusion of crambe grains reduced the rumen ammonia content (10.97 mg/dL); however, the ruminal pH was not altered by the inclusion of grains in the diet. Canola and soybean grains can be included in the cattle diet without altering dry matter intake; while the inclusion of crambe grains reduces the dry matter intake and the ruminal ammonia content of the animals. Crambe grain showed the highest recovery of dry matter and ether extract from feces.

title: Occurrence of vaccine abscesses in bovines after the administration of bivalent foot-and-mouth disease vaccine

description: ABSTRACT The aim of the present study is to identify the occurrence of abscesses in cattle after the administration of bivalent foot-and-mouth disease vaccine as adverse reaction to components in the new commercial vaccine formulation. Thirty bovines were divided into three groups composed of 10 animals, each. Groups 1 and 2 were vaccinated by researchers based on good vaccination practices criteria. Group 1 was intramuscularly administered with the vaccine, Group 2 received it through subcutaneous route and Group 3 was vaccinated by breeders through subcutaneous route. Animals were selected and observed in vivo in three different moments (7, 28 and 45 days after vaccination). Subsequently, they were observed during post mortem inspection in order to assess the occurrence of vaccine abscesses. Vaccine abscesses were recorded in 40% of bovines in Group 1, in 50% of the ones in Group 2 and in 60% of those in Group 3. There was no significant difference between experimental groups based on the Chi-square test and on Cramer's V analysis; there was no significant difference among experimental groups. Excess of carcass parts presenting vaccine abscesses during post mortem inspection resulted in the meat loss of 1.775 kg in Group 1, of 2.303 kg in Group 2 and of 3.268 kg in Group 3. In conclusion, despite changes in bivalent foot-and-mouth disease vaccine formulation, care should be taken at vaccination time to minimize the occurrence of vaccine abscesses and, consequently, meat losses at slaughter, as well as to reduce losses in beef production chain.

title: Visceral composition, carcass yield and meat quality parameters of free-range broilers with diets containing different levels of crushed sugarcane

description: ABSTRACT The aim of this study was to evaluate the visceral composition, cuts, and meat quality of two strains of free-range chickens fed diets containing crushed sugar cane. 448 chickens were distributed at 35 days of age, in two randomized blocks design, in 4x2 factorial, with four levels of replacement in the feed (0; 15; 30 and 45%) by sugarcane and two strains (Pesadão and Label Rouge), in two repetitions per block of fourteen birds per experimental unit. In 30 minutes after slaughter, the parameter a* was higher for animals of the Pesadão strain relation to the Label Rouge lineage. A quadratic effect was observed with increasing levels of sugarcane on the L* parameter of breast meat; and linear effect on parameter b* of the breast skin. Within 24 hours after slaughter, a quadratic effect of sugarcane levels was observed on the b* parameter of the breast meat. The increase in sugarcane levels linearly reduced the weight of heart, liver, chest, thigh plus drumstick, wing, carcass yield and relative heart weight of the animals. A quadratic effect was observed with increase in sugarcane levels over the relative weight of abdominal fat, the lowest fat content was observed in animals that consumed up to 30% of sugarcane in the feed. The use of sugarcane as an alternative feedstuff in up to 45% in the diet maintains the quality of meat and reduces the abdominal fat content, however, decreases the carcass yield.
