Genetic association among feeding behavior, feed efficiency, and growth traits in growing indicine cattle
(2020-01-01)
This study aimed to estimate genetic parameters, including genomic data, for feeding behavior, feed efficiency, and growth traits in Nellore cattle. The following feeding behavior traits were studied (861 animals with ...
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 ...
Preference for heights of feeding troughs in mares: a pilot study
(Univ Federation Animal Welfare, 2019-05-01)
Preferences for the height of feeding troughs of seven mares were evaluated and, as awareness of surroundings when feeding is adaptive for horses, the relationship between preference responses and attention behaviours was ...
Utilização de NaCl no suplemento como alternativa para viabilizar o sistema de alimentação de bezerros em creep-feeding
(2002-01-01)
Thirty two Canchim suckling calves, maintained on rotational grazing system of Brachiaria brizantha cv. Marandu, were divided in three groups corresponding to three evaluated treatments: control (without creep-feeding); ...
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 ...
Red Light Stimulates Feeding Motivation in Fish but Does Not Improve Growth
(2013-03-14)
Nile tilapia fish were individually reared under similar light levels for 8 weeks under five colored light spectra (maximum wavelength absorbance): white (full light spectrum), blue (~452 nm), green (~516 nm), yellow (~520 ...
Chemical and energy composition of broiler feeds
(Univ Federal Ceara, Dept Geol, 2016-10-01)
The aim of this work was to determine the chemical composition and values for apparent metabolisable energy (AME), and apparent metabolizable energy corrected for nitrogen (AMEn), in broiler feeds. In the experiment, 432 ...
Unravelling a vicious circle: animal feed marketed in Costa Rica contains irregular concentrations of tetracyclines and abundant oxytetracycline-resistant Gram-positive bacteria
(2014-04)
Diverse tetracyclines are used to prevent and control bacterial infections in livestock and farmed fish. These drugs are administered through the diet, but farmers seldom check whether feed contains antibiotic-resistant ...
Mudanças ontogenéticas na dieta de Oreochromis niloticus and Tilapia rendalli da represa de Barra Bonita (rio Tietê, Estado de São Paulo, Brasil)
(2012-07-11)
The Nile Tilapia, Oreochromis niloticus, and the Congo Tilapia, Tilapia rendalli, are important members of the African cichlids, and have been introduced to many Brazilian lakes and reservoirs. These species exhibit a large ...
Growth and gliotoxin production by feed-borne Aspergillus fumigatus sensu stricto strains under different interacting environmental conditions
(Wageningen Academic Publishers, 2015-01-22)
In this study the effects of temperature, oxygen tension, water activity (aW), pH, incubation time and their interactions on (1) the lag phase prior to growth, (2) growth rate and (3) gliotoxin production of two feed-borne ...
