| In this study, the Von Bertalanffy, Richards, Gompertz, Brody, and Logistics non-linear mixed regression models were compared for their ability to estimate the growth curve in commercial laying hens. Data were obtained from 100 Lohmann LSL layers. The animals were identified and then weighed weekly from day 20 after hatch until they were 553 days of age. All the nonlinear models used were transformed into mixed models by the inclusion of random parameters. Accuracy of the models was determined by the Akaike and Bayesian information criteria (AIC and BIC, respectively), and the correlation values. According to AIC, BIC, and correlation values, the best fit for modeling the growth curve of the birds was obtained with Gompertz, followed by Richards, and then... |

| Abstract: The objective of this work was to evaluate the effect of the inclusion of vegetable and mixed glycerin in the diet of broiler quail (Coturnix coturnix coturnix) on animal performance, yield of carcass and organs, and physical and sensory characteristics of the meat. A total of 432 quails aged 1-42 days were used in a completely randomized design with a 4×2+1 factorial arrangement (5, 10, 15, and 20% inclusion of vegetable or mixed glycerin, besides one treatment without glycerin) with 4 replicates of 12 birds each. Feed intake, weight gain, feed conversion, yield (carcass, breast, thigh+drumstick, heart, liver, gizzard, and abdominal fat), and physical and sensory characteristics of the meat. The diet containing mixed glycerin resulted in higher... |

| Three short tandem repeats (STRs), BMS1074, BM1500, IDVGA-51, and three single nucleotide polymorphisms (SNPs), LEPSau3AI (A/B), LEPSau3AI (+/-) and LEPKpn2I linked to the LEP gene were investigated to verify associations with productive performance in postpartum cows of two beef cattle breeds, Aberdeen Angus (AA, n=98) and Charolais (C, n=83). After polymerase chain reaction, STRs were analyzed by vertical electrophoresis and SNPs in agarose gel after endonucleases cleavage. In AA herd 79% of BMS1074*151 carriers had a lower average daily weight gain (ADG) when compared with the population mean daily weight gain (103g), while 62% of BMS1074*151 non-carriers presented a higher ADG (P<0.01); AA animals with at least one BMS1074*151 allele showed a ADG... |

| O objetivo do presente trabalho foi avaliar se a seleção para conversão alimentar (CA) e ganho de peso (GP), com base no desempenho individual e ou coletivo dos láparos, pode produzir ganhos genéticos em progênies criadas coletivamente, e animais submetidos à avaliação no período de 50 a 70 dias de idade, utilizando inferência Bayesiana. Realizaram-se seis análises bicaráter. No teste de desempenho foi observado que as características ganho de peso e conversão alimentar em ambos os ambientes tiveram valores para herdabilidade que variam de 0,42 a 0,60. Tanto a correlação genética 0,44 a 0,68 (GP) e 0,23 a 0,56 (CA) como a fenotípica 0,30 (GP) e 0,17 (CA) foram positivas para a mesma característica quando avaliada nos dois ambientes, coletivo ou individual,... |

| Empty body and carcass chemical composition were determined in 67 Nellore bulls from Selection Nellore (NeS) and Control Nellore (NeC) herds of an animal breeding program for growth, slaughtered at 570 days of average age, after 100 days of feedlot. Selection Nellore animals had, respectively, 360 and 430 kg of initial and slaughter body weight, and NeC animals had 318 and 373 kg for the same traits. Animals were slaughtered and empty body composition was determined by chemical analysis of the components blood, hide, head and feet, viscera and carcass. Tissue deposition rates and gain chemical composition were also determined based on gains estimated by comparative slaughter technique. Significant differences were detected between NeS and NeC animals for... |

| Our objective was to compare the use of calories from ethanol by well-nourished and malnourished rats in terms of body weight. Female Wistar rats weighing 170-180 g at the beginning of the study were used. The animals were divided into two groups (N = 12 each): group W received water ad libitum and group E an ethanol solution ad libitum as the only source of liquid throughout the experiment. The concentration of ethanol was increased weekly from 0 to 5, 10, 20 and 40% (v/v). In the well-nourished phase (A), all rats received food ad libitum (AW and AE). Ethanol treatment (AE) was then interrupted and water was offered to both groups. After 2 weeks both AW and AE rats were submitted to food restriction (50% of group AW food consumption), thus initiating the... |

| Analisaram-se as características de crescimento de 303 crias ovinas referentes aos grupos genéticos ½ sangue Somalis Brasileira x Sem Raça definida (SRD) e ½ sangue Santa Inês x SRD, do nascimento aos 140 dias de idade. Durante a época chuvosa, as crias foram mantidas em pastagem nativa e receberam suplementação mineral. Na época seca, foram submetidas a amamentação controlada e creep feeding com forragem e concentrado dos 15 dias de idade até o desmame, o qual ocorreu entre 70 e 84 dias de idade. Os resultados demonstraram que o grupo genético e o ano de nascimento das crias não influenciaram (P>O,05) nenhuma das características estudadas. O mês de nascimento influenciou (P<0,05) os pesos ao nascer, aos 56 dias de idade e ao desmame, bem como, o... |

| ABSTRACT The objective of this study was to evaluate the oxidative stability of cashew nut meal (CNM) at 180 days of storage and the effects of its use in the feed of meat quails. A total of 280 animals at seven days of age, of both sexes, were distributed in a completely randomized design with five treatments, in a 2 × 2 + 1 factorial arrangement, and seven replicates of eight birds each. The treatments were a control diet without CNM and diets containing levels of 12.5 or 25% of new CNM (NCNM) or stored for 180 days (SCNM). The lipid oxidation of the brans was evaluated by determining the acidity index and peroxide index. The parameters evaluated were the quail performance, metabolizable coefficients and energy of diets, carcass characteristics, relative... |

| Short stature, a marker for undernutrition early in life, has been associated with obesity in Brazilian women, but not in men. We tested the hypothesis that weight gain during the reproductive years could explain this gender difference. A national two-stage household survey of mothers with one or more children under five years of age was conducted in Brazil in 1996. The subjects were women aged 20 to 45 years (N = 2297), with last delivery seven months or more prior to the interview. The regions of the country were divided into rural, North/Northeast (urban underdeveloped) and South/Southeast/Midwest (urban developed). The dependent variables were current body mass index (BMI) measured, BMI prior to childbearing (reported), and BMI change. Socioeconomic... |

| ABSTRACT: This research aimed to assess Girolando calves’ concentrate intake and performance when placed in shelters with distinct roofing materials and programs of supplementary lighting during the milk-feeding stage. In order to so, we used a completely randomized design with a 3×3 factorial arrangement, with three replications. Females Girolando calves (n=27) were assigned in individual shelters at random with 3 different roofing materials (fiber cement tile, recycled tile and thatched roofs) and subjected to three lighting programs (12, 16 and 20 hours). No interaction was observed between roofing material and lighting programs, whilst no significant effect (P>0.05) was observed among the roofing materials. The supplementary lighting, by providing... |
