Residual feed intake of nellore calves is not repeatable across pre and post weaning periodsConsumo alimentar residual de bezerros Nelore na pré e pós-desmama tem baixa repetibilidade
(2021-01-01)
This study measured milk and solid feed intake in pre- weaning period and feed intake in postweaning period of Nellore calves, and to correlated them with performance traits and ingestive behavior of animals classified as ...
Association among residual feed intake, residual body weight gain, residual intake and body weight gain and temperament of Nellore cattle
(2014)
A study was conducted to investigate association among residual feed intake (RFI), residual body weight gain (RG), residual intake and body weight gain (RIG) and temperament of Nellore (Bos indicus) young bulls (n = 44; ...
Prediction of maximum scaled feed intake in broiler chickens based on physical properties of bulky feeds
(Taylor & Francis Ltd, 2020-08-17)
1. A trial was conducted to investigate the capacity of broiler chickens to consume bulky feeds during three stages of growth. These phases were from 1 to 15 d, 16 to 30 d and from 31 to 45 d. 2. A basal feed was serially ...
Genome-wide association analysis of feed intake and residual feed intake in Nellore cattle
(Biomed Central Ltd., 2014-02-11)
Background: Feed intake plays an important economic role in beef cattle, and is related with feed efficiency, weight gain and carcass traits. However, the phenotypes collected for dry matter intake and feed efficiency are ...
Feeding behavior of growing-finishing pigs reared under precision feeding strategies
(Amer Soc Animal Science, 2016-07-01)
The feeding behavior of growing-finishing pigs reared under precision feeding strategies was studied in 35 barrows and 35 females (average initial BW of 30.4 +/- 2.2 kg) over 84 d. Five different feeding programs were ...
Feeding level and frequency for freshwater angelfish
(Sociedade Brasileira de Zootecnia, 2012-06-01)
The objective of this study was to determine the optimal feeding level and feeding frequency for the culture of freshwater angelfish (Pterophyllum scalare). A randomized block design in a factorial scheme (3 × 2) with three ...
Test post-weaning duration for performance, feed intake and feed efficiency in Nellore cattle
(Sociedade Brasileira de Zootecnia, 2011-02-01)
O objetivo neste estudo foi determinar o melhor período de avaliação para medidas de desempenho, consumo e eficiência alimentar. Durante 112 dias, 60 machos da raça Nelore, recém-desmamados, submetidos à prova de ganho de ...
Feeding behavior of growing and finishing pigs fed different dietary threonine levels in a group-phase feeding and individual precision feeding system
(Oxford Univ Press Inc, 2020-10-01)
Feeding behavior is an important aspect of pig husbandry as it can affect protein deposition (PD) in pigs. A decrease in plasma threonine (Thr) levels may influence feed intake (FI) due to amino acid imbalance. We set out ...
Genetic parameter estimates for feed efficiency and dry matter intake and their association with growth and carcass traits in Nellore cattle
(Elsevier B.V., 2014-09-01)
This study estimated genetic parameters and (co)variance components for dry matter intake (DMI), average daily gain (ADG), feed conversion rate (FCR), residual feed intake (RFI), residual body weight gain (RWG) and residual ...
