Feeding pasteurized waste milk to preweaned dairy calves changes fecal and upper respiratory tract microbiota
(Frontiers in Veterinary Science, 2019-06-06)
In the present study bacterial communities from both, the gastrointestinal and respiratory tract of pre-weaned dairy calves fed two different milk-feeding programs were characterized using 16S rRNA gene sequencing. Twenty ...
How far are we from providing pigs appropriate environmental enrichment?
In vivo safety evaluation of the Clostridium butyricum MIYAIRI 588 strain in broilers, piglets, and turkeys
(Toxicology Research and Application, 2019-02-11)
Clostridium butyricum MIYAIRI 588 (CBM 588) is a nonpathogenic, anaerobic, gram-positive bacillus characterized by the production of short-chain fatty acids, including butyrate. The safety and tolerance of CBM 588 was ...
Effect of environmental temperature, floor type and breed on skatole and indole concentrations in fat of females, immuno-castrated and entire males
(Livestock Science, 2018-11-29)
The present study was divided in two different trials. The aim of the first trial was to determine if the thresholds of detection of skatole and indole are achieved in females and in males vaccinated against the GnRF housed ...
Analysis of porcine IGF2 gene expression in adipose tissue and its effect on fatty acid composition
(Plos One, 2019-08-08)
IGF2:g.3072G>A polymorphism has been described as the causal mutation of a maternally imprinted QTL for muscle growth and fat deposition in pigs. The objective of the current work was to study the association between the ...
Whole rumen metagenome sequencing allows classifying and predicting feed efficiency and intake levels in cattle
(Scientific Reports, 2019-01-09)
The current research was carried out to determine the associations between the rumen microbiota and traits related with feed efficiency in a Holstein cattle population (n = 30) using whole metagenome sequencing. Improving ...
Citrus aurantium flavonoid extract improves concentrate efficiency, animal behavior, and reduces rumen inflammation of Holstein bulls fed high-concentrate diets
(Animal Feed Science and Technology, 2019-10-10)
One hundred fourty-four bulls (164.8 ± 5.91 kg BW and 135 ± 7.2 d of age) were randomly allocated to one of 8 pens and assigned to control (C) or citrus flavonoid (BF) treatments (Citrus aurantium, 0.4 kg per ton of ...
Genetic parameters of sow feed efficiency during lactation and its underlying traits in a Duroc population
As a result of the genetic selection for prolificacy and the improvements in the environment and farms management, litter size has increased in the last few years so that energy requirements of the lactating sow are greater. ...
Bayesian hierarchical model for comparison of different nonlinear function and genetic parameter estimates of meat quails
(Poultry Science, 2018-12-07)
This study aimed to compare different nonlinear functions to describe the growth curve of European quails and to estimate growth curve parameters, (co)variance components, and genetic and systematic effects that affected ...
Indirect genetic effects on the relationships between production and feeding behaviour traits in growing Duroc pigs
Performance and feeding behaviour traits in growing pigs could be affected by social interaction effects when animals are raised in group. So, properly knowing the genetic correlations between direct and social interaction ...
