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,...

The use of genome-wide association results combined with other genomic approaches may uncover genes and metabolic pathways related to complex traits. In this study, the phenotypic and genotypic data of 1475 Nellore (Bos indicus) cattle and 941,033 single nucleotide polymorphisms (SNPs) were used for genome-wide association study (GWAS) and copy number variations (CNVs) analysis in order to identify candidate genes and putative pathways involved with the feed conversion ratio (FCR). The GWAS was based on the Bayes B approach analyzing genomic windows with multiple regression models to estimate the proportion of genetic variance explained by each window. The CNVs were detected with PennCNV software using the log R ratio and B allele frequency data. CNV...

The present study assessed the effect of adding water and phytase to middling diets on digestibility, metabolism, performance, carcass characteristics, and the bone mineralization of growing and finishing pigs. For the digestibility trial, 16 pigs were distributed in randomized blocks, placed in digestibility cages following a 2 x 2 factorial design (dry and wet diets, with and without phytase). For the performance trial, 48 piglets were distributed into a complete randomized design. During the growing period, wet diets presented higher values for digestibility and energy metabolism. In the finishing stage, the addition of water to the feed caused a greater weight gain and interfered with the carcass length. The balance of the mineral matter and the...

Effects of varying levels of distillers dried grains with solubles on growth performance of broiler chicks Rev. Bras. Ciênc. Avic.
Loar II,RE; Corzo,A.
There is no formal recommendation, regarding dietary concentration, when it comes to feeding distillers dried grains with solubles (DDGS) to young broilers. This study evaluated the effects of varying levels of DDGS in a diet to young broilers from 0 to 14d of age. Diets ranged from 0 to 32% DDGS concentration, with 8% increments. Increasing inclusion rate of DDGS led to decreased body weight gain (BWG), whereas mortality seemed to be linearly increased. However, there was an increase seen in feed conversion (FCR) in conjunction with the increase in DDGS in the diet. An inclusion level of 8% DDGS or less is recommended for starter diets for broiler chicks.

Evaluation of covering materials in individual shelters and its effects on physiological responses and performance of dairy calves REA
Fonseca,Patrícia C. de F; Almeida,Eduardo A. de; Passini,Roberta.
In Tropical regions, the animal performance is often affected by climate conditions. This study aimed to evaluate covering materials in individual shelters, normally used to house dairy calves, and its influence on the calves physiology and performance. The design used was completely randomized, with a 2x3 factorial arrangement to compare the averages of 5% through the Tukey's test, i.e., both genders- and three types of covering in the shelters (Z - zinc; AC - asbestos cement; and WPAC - white-painted asbestos cement). Parameters evaluated included daily weight gain (DWG), dry matter intake (DMI), feed conversion (FC), rectal temperature (RT), and respiratory frequency (RF). Results showed significant differences (P < 0.05) among males (1.04kg/day) and...

FREITAS, E.R.; FUENTES, M. de F.F.; SANTOS JÚNIOR, A. dos; GUERREIRO, M.E.F.; ESPÍNDOLA, G.B..
O objetivo deste trabalho foi avaliar o desempenho de frangos de corte alimentados com ração com farelo de castanha de caju (FCC). O delineamento experimental foi inteiramente casualizado, com seis tratamentos e oito repetições de 15 aves cada. Os tratamentos consistiram em seis rações isonutrientes com inclusão de 0, 5, 10, 15, 20 e 25% de ração com farelo de castanha de caju. O consumo de ração não foi influenciado pelos tratamentos. Entretanto, o aumento do FCC na ração promoveu aumento linear no ganho de peso, em todas as fases, e melhora linear na conversão alimentar, na fase inicial e no período total. Em relação ao controle, observou-se que, na fase inicial, as aves alimentadas com a ração com 25% de FCC apresentaram maior ganho de peso e melhor...

Five hundred and seventy-five Nellore steerswere evaluated for residual feed intake and residual feed intake and gain and their relationships between carcass, non-carcass and meat quality traits. RFI was measured by the difference between observed and predicted dry matter intake and RIG was obtained by the sum of ?1*RFI and residual gain. Efficient and inefficient animals were classified adopting ±0.5 standard deviations from RFI and RIG mean. A mixed model was used including RFI or RIG and contemporary group as fixed effects, initial age as covariate and sire and experimental period as random effects, testing the significance of the regression slope for each evaluated trait. RIG was positively related to longissimus muscle area. Efficient-RFI animals had...

Castilhos,André Michel de; Branco,Renata Helena; Corvino,Tatiana Lucila Sobrinho; Razook,Alexander George; Bonilha,Sarah Figueiredo Martins; Figueiredo,Leopoldo Andrade de.
Two Nellore herds were compared, one selected for greater postweaning weight and the other, control, selected for average postweaning weight, to evaluate the effects of 29 years of selection on feed efficiency. Sixty Nellore males (41 selected and 19 control) averaging 205 kg and 267 days of age were evaluated in individual pens during performance test. Performance and dry matter intake were used to determine the following feed efficiency traits: feed conversion; residual feed intake; residual gain; partial growth efficiency; relative growth rate and Kleiber ratio. After the 112-day experimental period, control animals showed lower body weight when compared to selected animals, however, they did not differ for dry matter intake (% of body weight), rib-eye...
