Effect of quantitative feed restriction and sex class on sheep skin quality.

The aim was to evaluate the quality of the sheep skin of different sex classes submitted to different levels of feed restriction. Sheep without defined racial pattern of different sex classes (15 non-castrated males, 15 castrated males and 15 females), with initial body weight of 18.1 ± 0.4kg and mean age of 90days were distributed in a factorial 3 × 3, with three sex classes and 3 levels of feed restriction (ad libitum intake and restricted intake at 70 and 80%), with 5 repetitions. After slaughter, the skins were collected for physical-mechanical tests. The effect of the sex classes x levels of dietary restriction interaction was observed for transverse thickness and longitudinal rupture elongation (p < 0.05). Animals fed ad libitum had greater longitudinal transverse thickness (p < 0.05). Animals fed ad libitum and 70% feed restriction showed greater transverse elongation at break (p < 0.05). As for the difference between sex classes in the transverse thickness variable for tearing strength, the interaction sex classes x levels of feed restriction for transverse thickness, longitudinal thickness, transverse tearing strength and longitudinal tearing strength occurred (p < 0.05). Feed restriction reduces the physical quality of the skin of sheep of different sex classes, and the use of castrated male sheep in positive energy balance is recommended to obtain leather with greater thickness, longitudinal rupture elongation and transverse tear strength.

Using multivariate analysis to predict carcass characteristics of lambs in grazing and supplemented with different levels of non-protein nitrogen

Abstract The aim of this study is to assess the effects of substituting soybean meal with extruded urea in the diet of crossbred Texel x no defined racial pattern lambs under continuous grazing on Brachiaria ssp., focusing on both their productive and nutritional performance. 60 Texel crossbred lambs (12 animals for each treatment) were used, with an average initial weight of 20.7 ± 0.87 kg and an average age of 2.5 ± 0.70 months, fed treatments with increasing levels of UE (Urea extruded Amireia® 200S): 0; 6; 12; 18 and 24 grams of EU 100/kg of body weight, with trial period was 5 months, using the multivariate technique. The data were subjected to principal component and canonical discriminant analysis to check possible differences between the evaluated treatments and identify the variables that best discriminate and use these variables to create a discriminant function that represents the differences between treatments. Of the 12 variables initially used, we observed that 9 were used by the main components, but 6 were those that presented the greatest discriminatory power for the study. Main component 1 was characterized by biometric measurements and showed the greatest power of variation in the study (60%), followed by main component 2, represented by slaughter weight and empty body weight (13%). These correlations indicate that biometric measurements can serve as reliable indirect indicators for estimating carcass traits in sheep, offering a practical alternative to visual assessments.

Evaluation of internal markers in digestibility estimation for sheep and goats.

The objective of this study was to compare the indirect methods of obtaining digestibility with the direct method of total fecal collection to estimate the apparent digestibility of nutrients in sheep and goats supplemented with non-protein nitrogen. Five goats and five sheep with no defined racial pattern were used, distributed in two 5 × 5 Latin squares, with split plots, considering the diets as plots and the apparent digestibility determination methodologies as subplots. The diets were composed of buffelgrass hay and the addition, via ruminal infusion, of increasing amounts of nitrogen supplementation in order to gradually raise the CP level of the basal diet in intervals of 2% points, that is, + 2, +4, + 6 and + 8%. Samples of the feeds offered, and the leftovers were collected daily during the five days of collection to determine the nutrient intake, as well as the total collection of feces to determine the apparent digestibility of the nutrients. The amount of fecal dry matter excreted was estimated by the concentration of Indigestible Acid Detergent Fiber (ADFi), Indigestible Neutral Detergent Fiber (NDFi), Indigestible Dry Matter at 244h (DMi 244h) and Indigestible Dry Matter at 264h (DMi 264h). Among the evaluated markers, DMi 264h had the lowest accuracy in estimating fecal excretion and nutrient digestibility. For the goat species, the markers ADFi and DMi 244h proved to be able to adequately predict fecal excretion and digestibility indices, while NDFi stood out for both species. Among the evaluated markers, NDFi is the one that most accurately estimates the nutrient digestibility of the diet for goats and sheep.

The Importance of Zero-Deficiency Complaints in Nursing Homes: A Mere Consequence or Serious Concern?

Complaints represent an important metric for assessing the quality of nursing home (NH) care. Using the Automated Survey Processing Environment (ASPEN) Complaints/Incidents Tracking System dataset (2017), we examined the relationships between zero-deficiency complaints (ZDCs) and zero-deficiency substantiated complaints (ZDSCs) and the proportion of residents with dementia. NHs (N = 15,339) were separated into three groups-proportion of residents with dementia in the top, two middle, and the bottom quartiles. Negative binomial regressions assessed zero-deficiency complaint patterns in relation to NHs' proportion of residents with dementia, controlling for facility characteristics, staffing, and racial pattern. We reported average marginal effects (AMEs) and 95% confidence intervals (CIs). NHs in the top quartile yielded higher numbers of both ZDC (AME = .189, 95% CI: .102-.276, p < .001) and ZDSC (AME = .236, 95% CI: .094-.378, p = .001), than NHs in the bottom quartile. Results suggest a need for more uniform investigation processes and staff training to promote a more valid complaint process for residents with dementia.

“What's your accent, where are you from?”: Language and belonging among older immigrants

Researchers have identified immigration and marginalization as two processes that impact older immigrants' experience of aging in the U.S. Our paper draws on 42 interviews with a diverse group of older American immigrants to center issues of language, accent, and Othering. We argue that the importance of language extends beyond communication for older immigrants, as English proficiency and accent are important boundaries determining inclusion and recognition as an American. Accents are a racialized characteristic that can prompt microaggressions and exclusion. We identified a racial pattern in reported reactions to accents among the participants in our study. White immigrants generally described positive appraisals of their accent, and typically had a choice whether to emphasize their national origins. While white immigrants were viewed as “Acceptable Outsiders,” many immigrants of color described microaggressions, ridicule, and discrimination related to their accented speech. We contend that these experiences of Othering can have a profound impact on sense of belonging, as many of the older immigrants of color in our study expressed a persistent sense of exclusion and even alienation. We advance the concept of “aging off center” to describe how repeated experiences of Othering and exclusion shape aging experiences for immigrants of color who are long-term residents of the United States.

Blood biochemical, hormonal, and hematological responses of native sheep submitted to different environmental conditions

The aim of this study was to evaluate the biochemical, hormonal, and hematological blood responses of native sheep subjected to five temperatures (20°, 24°, 28°, 32°, and 36 °C), using 24 sheep of the following breeds: Santa Inês (SI), Morada Nova (MN), Soinga (SO) and no defined racial pattern (NDRP), kept in collective pens inside the climatic chamber. The experimental design was completely randomized, in a 5 × 4 factorial scheme (5 temperatures and 4 breeds) with 6 animals of each breed at each temperature. There was interaction for urea (P < .0001), glucose (P < .0001), cholesterol (P < .0001), and magnesium (P < .0001) as a function of breed and air temperature. Urea (P = .001), glucose (P < .0001), triglycerides (P = .033), cholesterol (P = .004), and magnesium (P < .0001) showed differences according to breed. It was observed that T4 (P < .0001) and cortisol (P < .0001) showed an interaction between breed and temperature, while T4 (P = .001) and cortisol (P = .001) an effect of breed. The highest magnesium concentration was observed in MN, and the lowest was in NDRP, SO, and SI, which are statistically similar, and SI and NDRP are statistically similar. The hormones showed a significant effect (P < .0001) for temperature, where cortisol increased, and thyroid hormones decreased with increasing temperature. Temperatures of 32° and 36 °C contribute to changes in blood, hormone, and hematological biochemical responses of native sheep.

Orange molasses as a new energy ingredient for feedlot lambs in Brazil.

The objectives of this experiment were to evaluate the effects of increasing levels of orange molasses in replacement of flint corn grain in high-concentrate diets on dry matter intake (DMI), average daily gain (ADG), and feed efficiency (FE) of feedlot lambs. Thirty male lambs without defined racial pattern (30.3 ± 5.3 kg of initial BW; mean ± SD) were used in a randomized complete block design with 10 blocks and 3 treatments. The treatments were defined by partial replacement of flint corn by orange molasses in the diet with 90% of concentrate and 10% of Cynodon spp. hay, as follows: 0OM-control diet without orange molasses; 20OM-20% of orange molasses replacing flint corn; and 40OM-40% of orange molasses replacing flint corn (DM basis). The experiment lasted 72 days divided into 3 subperiods, with 1 subperiod of 16 days and 2 subperiods of 28 days. Animals were weighed after a 16-h fast on days 1, 16, 44, and 72 of the experimental periods to determine the ADG and FE. The DMI, ADG, and FE showed an interaction between treatments and experimental periods. The DMI in the first period decreased linearly (P < 0.01); in the third period, there was no effect of treatments (P > 0.05) on DMI. The ADG decreased linearly (P < 0.01) in the first period as the orange molasses increased. Otherwise, in the third period, ADG increased linearly (P = 0.05) as flint corn was replacement by orange molasses. The FE showed an interaction between treatment and period (P = 0.09). The first period had a decreased linear effect; in the third period, there was a trend (P = 0.07) of increased linear effect. There was no difference between the diets regarding the final BW of the lambs. In conclusion, the orange molasses can replace up to 40% of flint corn in diets for feedlot lambs without affecting final BW. However, it is important to consider the adaptation time proved to be very important for better use of orange molasses as a source of energy in diets for lambs.

Carcass characteristics and meat quality of goats fed increasing levels of crude glycerin.

Crude glycerin is a byproduct of the biodiesel industry and has been widely used in ruminant diets as a source of energy, usually in place of corn, primarily during periods of drought in tropical regions. The objective of this study was to evaluate the effect of including levels of the crude glycerin of low purity (0, 6, 12 and 18%) replacing corn in the diets of goats on the carcass characteristics, tissue composition, meat cuts yield and physicochemical parameters of meat. Forty males castrated without defined racial pattern goats an initial average weight of 19.70 ± 2.30 kg were slaughtered after 86 days. Diets content 0 and 6% crude glycerin promoted similar responses to the analyzed variables, except for pH and breast weight. No differences were observed to total digestible nutrients, slaughter body weight, commercial cut yield leg tissue composition and physicochemical parameters of meat. Crude glycerin can be included up to 12% without losses on carcass weight and meat cuts, leg composition, and meat quality. The inclusion of crude glycerin containing 63.06% glycerol and 45.57% lipids could be effective in partial replacement of corn in diets for confined goats in tropical areas.

Fine-scale genetic diversity of the Brazilian Pantaneiro horse breed adapted to flooded regions.

Among the animal species first introduced in Brazil during the country's discovery, horses (Equus caballus) stand out because of their evolutionary history and relationship with humans. Among the Brazilian horse breeds, the Pantaneiro draws attention due to its adaptative traits. Blood samples of 116 Pantaneiro horses were divided into six populations based on their sampling location, aiming to identify the existence of genetic structure and quantify genetic diversity within and between them. Populations were compared to elucidate genetic variability and differentiation better and assess the impact of Pantanal's natural geographic barriers on gene flow between populations. Data from the GGP Equine BeadChip (Geneseek-Neogen, 65.157 SNPs) was used to assess basic diversity parameters, genetic distance (FST), principal component analysis (PCA), and population structure (ADMIXTURE) for the sampled animals. Mantel test was also performed to investigate the correlation between the populations' genetic and geographic distances. Results showed high genetic variability in all populations, with elevated levels of admixture in their structure. High levels of admixture make it challenging to establish a racial pattern and, consequently, populations within the breed, being that only one of the populations differentiated itself from the others. No significant correlations between genetic and geographic distances were observed, indicating that environmental barriers did not hinder gene flow between populations, and neither farmers' selection practices might have change breed genetic composition significantly. Low genetic distance and similar heterozygosity values were observed among populations, suggesting strong genetic proximity and low differentiation. Thereby, the Pantaneiro breed does not exhibit genetic subpopulations and could be considered, for conservation purposes, a single big population in the Panatnal region. This study will support sampling strategies for National genebank.

Quantitative analysis of echotexture and testicular biometry in asinines used in animal-drawn vehicles

Testicular ultrasound analysis is a non-invasive diagnostic method and an important step in andrological examination, which enables the early assessment of fertility disorders. Given the importance that asinines have for low-income families, and the need for experiments to establish these patterns of andrological evaluation for donkeys, this study aims to quantitatively determine the testicular echogenicity without a defined racial pattern, as well as to evaluate the testicular biometry and ultrasound changes observed in the testicles of these animals. 30 asinines without a defined racial pattern were used, divided into two groups according to age group (AG1 - 15 animals from 16 to 50 months of age and AG2 - 15 animals over 50 months of age and maximum 130 months). Ultrasound scanning was performed in longitudinal and transverse sections of the testicles. The images obtained were analyzed using GIMP 2.8 software (2012) and a standard gray scale graph (histogram) was generated. The AG2 group showed a significant difference in testicular length, width, and height (P 0.05) between echogenicity (gray scale histogram) of the parenchyma and left testicular mediastinum, between the studied age groups. There was a significant difference (P < 0.05) between the echogenicity of the mediastinum of the right testicle between the age groups. Key words: Diagnostic imaging, reproduction, ultrasound, asinines.

Avaliação de sistemas de produção e análise econômica de cabritos lactentes criados na região semiárida da Paraíba

The objective of this study was to evaluate the performance and economic indicators of baby goats region submitted to different feeding systems in the Semiarid. A total of 30 baby goats of breed Parda Alpina × without defined racial pattern (SPRD) with initial weight of 3.35 kg ± 0.65 kg and final weight of 12.3 kg ± 0.5 kg were used, distributed in a completely randomized design in three breastfeeding systems with ten replicates each: traditional system (with natural breastfeeding), intensive breastfeeding system without concentrated supplementation, and intensive breastfeeding with concentrated supplementation. Goats submitted to the intensive artificial feeding system without concentrated supplementation showed a similar weight gain (121 g/day) when compared to the goats submitted to the system of suckling with concentrated supplementation (126 g/day). The highest income was provided by the animals submitted to the intensive system of suckling with concentrate. The gross margin for the two centenarians was positive, that is, revenues are higher than the effective operating cost, allowing us to conclude that the activity is paying off and will survive, at least in the short term. The diet of kids using concentrate provided better dry matter intake, greater weight gain and consequently presented better economic indicators.

Racial Capitalism and COVID-19

The COVID-19 pandemic has brought into sharp relief the deep structural problems affecting nonwhite racialized workers in the core and periphery. Yet, many social scientific analyses of the global political economy, at least in the pre-COVID era, are race neutral or willfully indifferent to the persistent racial pattern of global inequalities. Even if they do address legacies of colonialism, they ignore the ongoing racial logics of oppression embedded therein.

Analysis of added value in bovines sold for the angus meat program in the south of Brazil

The objective of this work was to analyze price aggregation and disaggregation in commercialized animals searching for "Programa Carne Angus" benefits in the state of Rio Grande do Sul, Brazil. Data from 40,698 carcasses with Angus cattle racial pattern, slaughtered in a meat industry that performs the "Programa Carne Angus "certification, during the 2014 year were analyzed. The aggregated value was calculated by the difference between the negotiated base price for the lot and the final price obtained by animal after the certification process. The disaggregation was calculated based on the factors preventing the animals from being included in the certification program. The results show that the major disqualifying factor in males with the racial pattern was carcass fatness, and for females was the dentition, which disqualified 34.3 and 12.7% respectively. Value breakdown from 7,177 disqualified animals due to lack of finishing, or advanced dentition, reached R$ 1,213,528.00, or US$ 369,077.86 (US$ 51.43 per head), an amount that is no paid on from the industry to rural producers.Keywords: Aberdeen Angus, beef cattle dentition, beef cattle meat chain, fatness carcass, quality meat.

Effects of High-Grain Diet on the Quality of Meat and Carcass of Lambs and Economic Indices of Various Diets

The Brazilian sheep farming sector suffers from low productivity, related to the extensive animal production system and low availability of native fodder during most of the year. An alternative to the systems would be the use of a diet without roughage, allowing greater weight gain and better quality carcasses. The aim of this study was to investigate the effects of diets containing different proportions of grains on the quality of carcass and meat of lambs as well as the economic indices of various diets. Three diets containing different proportions of concentrate and roughage (100:0, 80:20, and 60:40) were supplied. The concentrate comprised 85% whole-grain corn and 15% commercial pelletized supplement. Twenty-four male lambs (no racial pattern; average body weight, 20.9 &amp;plusmn; 1.0 kg; age, 6 months) were randomly allotted to three collective bays for 52 days. Subsequently, the animals were slaughtered, and further analyses were performed. The diet with 100% concentrate achieved overall higher carcass yield, lower weight loss on cooking, and greater lipid oxidation. However, no diet affected weight gain, slaughter weight, carcass length and thorax depth, pH, temperature, color, water-holding capacity, and meat shear force (P &amp;gt; 0.05). The best economic indices were obtained with the diet containing 100% concentrate. Therefore, based on the results obtained, the use of 100% concentrated diet for lambs is the most suitable practice to improve the sheep production from a productive and economic point of view.

Impacto do pré dipping, padrão racial e ordem dos jatos de leite sobre a atividade microbiológica e físico-química do leite cru bovino

ABSTRACT: Dairy cattle farming is one of the main economic activities in Brazil, playing an important role in the income of millions of families and in quality food. The objective was to study the influence of the racial pattern and the dare of pre dipping on the microbiological and physical-chemical compositions of raw bovine milk. The study was carried out in Santana do Ipanema, a municipality located in the Brazilian Semiarid Region. The treatments consisted of the evaluation of the order of the jets, racial pattern (Girolando and Holonesa) and the adoption of pre dipping, each group had ten animals. The order of the milk jets promoted a linear decreasing effect (P 0.05) the count of total bacteria, protein, added water, cryoscopic index and milk density, however the Girolando breed has lower fat content and pH (P <0.05) of milk higher in relation to Holstein animals. The use of pre dipping reduced (P <0.005) the total bacteria count in 0.80 CFU mL-1 of milk. The advancement of milking (milk jets) and the use of pre dipping promotes a decrease in the bacterial load of the roof, justifying the need to dispose of the first three milk jets. KEYWORDS: Milk Breeds; Semi-Arid; Quality.

Canal flare index evaluation for different dog breeds

ABSTRACT: This study determined the canal flare index (CFI) of four dog breeds using two distinct femoral regions as a reference. Thirty-five radiographs of the hip joints of Golden Retrievers (GRG), German Shepherds (GSG), Labrador Retrievers (LRG), and Rottweilers (RG) of both sexes were used. Seventy experimental units were submitted to CFI calculation. Objective (CFIob) and subjective (CFIsub) values of the CFI of each experimental unit were determined according to the anatomical reference used for the calculation. A significant difference in the CFIob between the Golden Retriever and German Shepherd breeds (1.68 ± 0.16 and 1.49 ± 0.08), and in the CFIsub between Golden Retriever, German Shepherd, and Rottweiler breeds (2.09 ± 0.31, 1.86 ± 0.11, and 1.84 ± 0.18) was reported. The subjective form of measurement showed higher values than the objective form (GRG: 2.09 ± 0.31; GSG: 1.86 ± 0.11; LRG: 2.07 ± 0.12; RG: 1.84 ± 0.18). The CFI values of each breed were similar, suggesting a certain racial pattern. A significant difference in the interobserver assessment for both CFIsub and CFIob, in all races was observed. The CFI analysis identified morphological patterns of the proximal femur in the different races. Results indicated the need for standardization of the anatomical references used to calculate the CFI because there were statistical differences among the measurements among the observers.

Hemorrhagic Septic Thrombophlebitis in Horses

Background: Thrombophlebitis represents the main disease of the cardiovascular system of horses, its occurrence is strongly associated with the use of inappropriate materials and techniques. Its clinical presentation varies according to the degree of vessel obstruction and the appearance of complications, in the diagnosis it is essential to assess the extent of damage and the severity of the case. Establishing appropriate treatments, it should be noted that these are mostly clinical, reserving surgical interventions for severe cases, so the aim of the study is report a case of hemorrhagic septic thrombophlebitis treated by partial phlebectomy of the left jugular vein.Case: A 9-year-old male castrated equine, with no defined racial pattern, weighing 345 kg, used in the practice of vaquejada was attended at the Veterinary Hospital (HV) of the Federal University of Campina Grande (UFCG), Campus Patos (PB). During the anamnesis, it was reported that the animal presented colic a month ago, it was treated, recovered and since then, it started presenting an area with increase in volume in the neck region that ruptured the day before the HV attendance, where blood and pus came from. On physical exam, slight edema was noted in the left masseteric region, a volume rise involving the middle and cranial third of the neck with firm consistency in the left jugular sulcus, sensitivity to palpation and little drainage of purulent bloody secretion was observed. Additionally, tachycardia, tachypnea and intestinal hypomotility were found. In turn, in the ultrasound exam, a hypoechoic structure was seen, causing partial obstruction of the vessel, proximal to the fistulated region and total obstruction distal to it. With this information, antibiotic therapy was prescribed, a warm compress followed by the use of anti-inflammatory gel every 8 hours. By choice of the owner, the animal returned to the farm, in the next day returned to the Veterinary Hospital, due to extensive bleeding observed on the estate, immediately tried to stanch the bleeding by compressive banding, without success, we opted for the surgical intervention aiming to perform ligation and partial resection of the jugular vein. Pre-anesthetic medication was performed and under general anesthesia a rectilinear incision was made over the left jugular vein of the neck caudal region to bifurcation of lingual and facial veins, blunt dissection aiming to loosen the vessel and hemostasis of the installed neovascularization, transfixing proximal ligation with 1-0 nylon thread, diaeresis, removal of the vessel, reduction of the subcutaneous space, application of drain, dermorrhaphy in simple continuous pattern and use of compressive curative. For the postoperative period, maintenance of the initial antibiotic therapy was prescribed, adding flunixin meglumine 1.1 mg/kg, i.m, SID, 4 applications, tetanus serum 5000 UI/IM, antiphlogistic massage in the masseter region and wound treatment by washing with hypersaturated solution, use of sugar, healing pomade and repellent. One month after surgery, the animal received medical release with satisfactory healing, recovery from anemic and infectious condition, without circulatory complications.Discussion: The present report shows the feasibility of unilateral partial phlebectomy of the jugular vein as a therapeutic option in complicated cases of thrombophlebitis. In which thrombectomy techniques are contraindicated and ineffective clinical treatments, another alternative is vascular transplantation, which encounters many logistical difficulties in the routine. Despite the interruption of blood flow being pointed out as an aggravating factor, it should be noted that often thrombophlebitis itself leads to this condition, and the development of collateral circulation secondary to venous flow obstruction has been observed.

Identification of Races of Fusarium oxysporum f.sp. ciceris, Inciting Wilt of Chickpea in Andhra Pradesh and Parts of Telangana

Background: Fusarium oxysporum f.sp. ciceris (Foc) is one of the most important pathogen, causing wilt of chickpea. It is soil and seed borne pathogen. A serious threat in Foc is the evolution of new races, which reduces exploitation of wilt resistance in the crop in a particular area. Eight races (race 0, 1A, 1B/C, 2, 3, 4, 5 and 6) were reported in the world and among them four races (race 1, 2, 3, 4) were from India. Race 1 was reported from Andhra Pradesh. It is very important to monitor the variation regularly in new isolates collected from different varieties or genotypes and different geographical regions to identify the racial pattern. Development of SCAR markers for identification of Foc isolates is also important as they are highly reliable. Methods: Twenty isolates of Fusarium oxysporum f.sp. ciceris were obtained from wilt infected plants of chickpea covering different places of Andhra Pradesh including two isolates from Telangana and confirmed the pathogen based on pathogenicity test. They were tested on host differentials of chickpea for races identification. Among these twenty isolates five most virulent isolates (Foc-6, Foc-10, Foc-12, Foc-17 and Foc-24) were selected for RAPD based on pathogenicity test and SCAR marker was developed based on DNA banding pattern during RAPD for one isolate.Result: Based on the disease reaction on differentials, concluded that 17 of them out of 20 were matched with race-1 reaction. Two isolates were matched with race-6 reaction and one is not matched with none of the races. An amplified product of polymorphic band of approximately 700 bp in the isolate Foc-12, obtained during RAPD analysis was selected for SCAR marker development and two SCAR markers were developed and validated. Identification of races mainly helps in development of resistant cultivars to specific races and might be contributed to development of integrated disease management practices for Fusarium wilt.

Desempenho e comportamento ingestivo de cordeiros alimentados com dieta de alto grão

Neste estudo investiga-se o efeito de diferentes composições de dietas de alto grão na terminação de cordeiros sobre o desempenho e alterações no comportamento ingestivo e fisiológico. Foram utilizados 24 cordeiros machos, sem padrão racial definido com peso inicial médio de 20,9 kg, com 6 meses de idade. Foram elaboradas três dietas com diferentes proporções de concentrado e volumoso (100:0, 80:20 e 60:40), sendo a porção concentrada das dietas compostas por grão de milho inteiro associando ao suplemento protéico-mineral-vitamínico. Não houve efeito (P &gt; 0,05) das dietas teste para os consumos de matéria seca (MS), matéria mineral (MM), fibra em detergente neutro (FDN), carboidratos totais (CT) e nutrientes digestíveis totais (NDT), expressos em g/dia e % de peso vivo. As médias de ganho de peso total e diário e peso de abate foram semelhantes (P &gt; 0,05) entre as dietas, registrando-se ganho de peso diário de 0,302, 0,254 e 0,259 g/dia com 100, 80 e 60% de concentrado, respectivamente. Os cordeiros alimentados exclusivamente com concentrado diminuíram o tempo dedicado a ruminação (P ≤ 0,05), e apresentaram maior eficiência na alimentação (EAL) e ruminação (ERU). Os animais da dieta sem volumoso apresentaram acentuada variação de temperatura na região do rúmen, enquanto que cordeiros das dietas com 80 e 60% de concentrado apresentaram alterações de temperaturas próximas no mesmo período de avaliação. Todas as dietas avaliadas apresentaram desempenho satisfatório, e apesar das alterações observadas no comportamento ingestivo dos animais, essas não foram suficientes para prejudicar os índices de desempenho dos cordeiros.

Avaliação da distância intercaninos e sua correlação com as más oclusões

O objetivo deste trabalho é avaliar a correlação entre a distância intercaninos e as más oclusões. Tratou-se de um estudo observacional e prospectivo, cujos dados foram coletados de 110 documentações ortodônticas e modelos de estudo, de pacientes entre 12 e 35 anos. As variáveis estudadas foram: idade, sexo, padrão racial, relação molar de Angle, más oclusões e distância intercaninos. Os dados foram anotados em formulário específico e distribuídos em tabelas, onde aplicou-se a estatística analítica através dos testes t Student e ANOVA (p&lt;0,05). Os resultados foram os seguintes: a média de idade foi de 17,7 anos; a maioria da amostra foi do sexo feminino (58,7%) e de feodermas (43,6%). A relação de Classe I apresentou maior frequência (46,4% direita; 49,1% esquerda) e a má oclusão mais prevalente foi o apinhamento dentário (67,7%). As médias das distâncias intecaninos foram: 33,98mm, para a arcada superior e 26,11mm para a interior. A distância intercaninos na arcada superior de homens, foi estatisticamente maior que nas mulheres; assim como os arcos inferiores de jovens de 12 a 20 anos, foram maiores do que os de adultos de 21 a 35 anos. Concluiu-se que não houve correlação significativa entre a distância intercaninos e as más oclusões.
