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 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...

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...

Genetic parameters for performance and carcass traits in a paternal 1 lineage of broiler Anais da ABC (AABC)
CRUZ,VALDECY A.R.; GRUPIONI,NATALIA V.; MENDONÇA,GABRIELA G.; VENTURINI,GUILHERME C.; LEDUR,MONICA C.; PEIXOTO,JANE O.; MUNARI,DANISIO P..
Abstract The objective of this study was to estimate variance components for performance and carcass traits in a paternal broiler line. The (co)variance components were estimated by the restricted maximum likelihood method applied to the animal model, including the fixed effect of group (sex and hatch) and additive genetic and residual as random effects. Estimated heritability for performance traits ranged from 0.09 to 0.42. The genetic correlations between traits ranged from -0.50 to 0.97. The heritability estimates of feed intake, weight gain, and feed conversion from 35 to 41 days of age were of low magnitude. The genetic correlations among them were favorable to genetic selection. These results suggest that moderate genetic gain can be obtained to the...

In the search for low-cost year-round feeds: Pen-level growth performance of local and crossbred Ugandan pigs fed forage- or silage-based diets versus commercial diet JARTS
Carter, Natalie Ann; Dewey, Catherine Elizabeth; Grace, Delia; Lukuyu, Ben; Smith, Eliza; de Lange, Cornelis.
Smallholder pig farmers in East Africa report that lack of feed, seasonal feed shortages, quality and cost are key constraints to pig rearing. Commercially prepared pig diets are too expensive and people and pigs compete for food. Smallholder farmers typically feed nutritionally unbalanced diets, resulting in low average daily gain (ADG) and poor farmer profits. Our objective was to compare the ADG of Ugandan pigs fed forage- or silage-based or commercial diets. Ugandan weaner-grower pigs were randomly assigned to forage- or silage-based diets or commercial diet. Pigs were weighed every 3 weeks from 9 to 32 weeks of age. Pen-level ADG and feed conversion were compared across diets using multiple linear regression. The ADG of pigs fed forage- or...

Milk production and economic assessment of cassava bagasse in the feed of dairy cows Animal Sciences
Lima, Leandro Pereira; Veloso, Cristina Mattos; Silva, Fabiano Ferreira da; Pires, Aureliano José Vieira; Teixeira, Fábio Andrade; Nascimento, Paulo Válter Nunes.
The addition of 0; 5; 10 and 15% cassava bagasse, based on the dry matter of the total diet of crossbred Holstein v. Zebu cows, was evaluated on milk production and composition and on the impacts of diet costs. The animals, weighing an average of 478.5 kg, were in the middle third lactation period. Diet with 15% cassava bagasse provided a 13.2% increase in production when compared to control. Feed conversion had a quadratic effect with minimum point at 4.2% of cassava bagasse inclusion. Crude protein, the only milk component that changed, increased linearly with the inclusion of cassava bagasse levels. Treatment with 15% cassava bagasse caused a more effective operational cost (42.8% higher when compared to control) and the highest leveling point for milk...
