A 42-day study was conducted to evaluate the effect of genotype: terminal sire line Duroc × F1 (DC×F1); Embrapa MS-115 (MS-115×F1); and Moura (MS-115×MO) three dietary oil sources: soybean; canola; canola + flax, on performance, carcass traits, pork quality, fatty acid composition. Genotype affected technological quality profile. MS-115-sired pigs had better meat color Duroc-sired higher intramuscular fat content, more saturated omega-6/omega-3 ratio. breed influenced positively tenderness...
Genomic regions under high selective pressure present specific runs of homozygosity (ROH), which provide valuable information on the genetic mechanisms underlying adaptation to environment imposed challenges. In broiler chickens, conventional production systems in tropical environments lead animals with favorable genotypes be naturally selected, increasing frequency these alleles next generations. this study, ~1400 chickens from a paternal line were genotyped 600 K Affymetrix® Axiom®...
The performance of three hair sheep breeds (Brazilian Somali, Morada Nova, and Santa Ines) was evaluated in the production environment northeastern Brazil. Data from a total 524 lambs sired by 21 rams out 190 ewes were analyzed. These data collected 1980 to 1983 at Sobral, Brazil an experiment designed compare breeds. traits included weights birth, weaning, 8 mo, 10 yearling ages ewe characters weight lambing (EWT), lamb born (LWB), weaned (LWW), prolificacy rate (PR). Differences (P < .01)...
Com o objetivo de testar materiais alternativos para cama aviário na criação frangos corte, foram alojados seis lotes consecutivos, cada um contendo 5.600 aves, apenas fêmeas, distribuídas em 35 boxes. Os tratamentos consistiram sete tipos material (maravalha; casca arroz; sabugo milho triturado; capim-cameron picado; palhada soja picada; resto da cultura do e serragem), com cinco repetições. Avaliaram-se nas aves peso corporal médio consumo ração e, camas, os teores N, Ca, P pH....
ABSTRACT: The objective of this study was to assess the effects including grape pomace in diet pigs on pork quality and oxidative stability body fat enriched with omega-3 fatty acids. Four treatments were compared: T1) Control based corn soybean meal; T2) Diet inclusion 3% a canola (50%) flaxseed oil blend; T3) blend sequential levels 3 5% pomace; T4) 6 10% pomace. Inclusion led an increase (P<0.10) a* value color saturation index meat. polyunsaturated acids (PUFA) content backfat...
Reproductive traits as number of piglets born (NPB) and weaned (NWP) are directly related to the economic efficiency swine production systems. Pig breeding programs seek increase per sow year, NPB is among factors that indirectly influence NWP. Thus, multi-trait evaluations essential estimate heritabilities mainly genetic correlations between these over different farrowing orders. In general, Gaussian linear mixed models have been used evaluation litter traits; however since characterized...
We aimed to estimate litter size and uniformity genetic parameters trends of Landrace pigs at birth three weeks by using multitrait analyses for 2,787 litters. The following traits were evaluated: number piglets born alive (NBA), within-litter weight mean (MBW), standard deviation (SDB), coefficient variation (CVB), (NT), (MT), [...]
Estipulou-se como objetivos experimentais avaliar os parâmetros produtivos das linhagens da EMBRAPA e compará-los a duas marcas comerciais no período de 1-56 dias, o trabalho experimental foi realizado Centro Nacional Pesquisas em Suínos Aves, EMBRAPA, localizado na cidade Concórdia, Santa Catarina, 06 julho 2001 30 agosto 2001, totalizando 56 dias experimento. Cada box possuía 1,65m X 1,75m, lotação inicial era 40 animais por (13,88 frangos m-2), separados sexo linhagem. Foram utilizados 48...
O objetivo deste trabalho foi avaliar a influência do genótipo e de teores aminoácidos na dieta sobre o desempenho suínos, retorno econômico qualidade da carcaça carne. Os genótipos avaliados foram: MS115 x F1; Duroc F1 (DCxF1); Moura (MS115xMO); 25% Duroc, 50% Large White, (DCxMO3). nas dietas foram os recomendados para alto ou médio machos castrados com potencial genético. escore marmoreio mais elevado nos animais alimentados médios aminoácidos. DCxF1 DCxMO3 tiveram maior ganho peso diário...
Estimativas dos parâmetros genéticos e fenotípicos de algumas características produtivas em linhagem paterna matrizes frango corte foram obtidas utilizando-se a metodologia modelos mistos. Utilizaram-se dados aproximadamente 46.000 aves, originados 12 gerações no período 1992 2003, fornecidos pela EMBRAPA Suínos aves. Nos machos avaliadas as peso corporal aos 42 dias idade (P42), comprimento peito (CPeito), largura maior do (Larg1) menor (Larg2) idade. Os componentes variância co-variância...
O objetivo deste trabalho foi avaliar o efeito do sistema de alojamento sobre desempenho zootécnico, as características da carcaça, a qualidade carne e condição sanitária suínos criados em seis diferentes sistemas. Foram usados 803 mestiços MS58 x (Landrace Large White) sete lotes seqüenciais no tempo, avaliando fases creche crescimento-terminação. Na creche, foram avaliados três tipos alojamento: confinado convencional (CO); cama sobreposta-(CS); intensivo ao ar livre (SISCAL). No...
SUMMARY We aimed to compare multi-trait and repeatability models estimate genetic parameters for the traits number of piglets born alive (NBA) at 3 week age (NP3), litter weight birth (LW0) (LW3), mean piglet (MW0) (MW3), considering first three farrowings Landrace sows. Heritability (h2) estimates showed an increasing pattern up third farrowing LW0 MW3. For NBA, NP3, LW3, MW0 h2 increased from second decreased farrowing. In general, heritability estimated in model was lower than model. The...
This study aimed to estimate genetic parameters for five traits related performance and carcass in a terminal pig sire line using multitrait (MUV) reduced rank animal models, analyze the relationship between breeding values (EBVs) of principal component analysis (PCA) applied directly on mixed model equations (one-step PCA) EBVs obtained MUV (two-step PCA). The heritabilities were very similar both procedures ranged from 0.032 ± 0.014 feed conversion 0.102 0.029 lean meat. Except some...
An alternative procedure was developed to preserve White Leghorn spent hen meat using a drying process after heavy salting with NaCl, technique similar the familiar preparation method used for South American beef charqui meats. With breast and thigh samples, following hurdle measures were applied inhibit microorganism growth: plus antioxidants, drying, vacuum packaging. The products obtained classified as being intermediate in moisture, having relative long shelf life at room temperature...
