Efeitos do tipo de ração inicial sobre a morfologia intestinal e digestibiliade dos nutrientes em leitões
(1996-09-01)
Thirty piglets, weaned at an average age of 28 days, were used in experiment one. After weaning, 24 animals were transferred to the nursery in groups of two to each pen and fed simple or semi-complex diets ad libitum. On ...

Effect of breast feeding time on physiological, immunological and microbial parameters of weaned piglets in an intensive breeding farm
(Elsevier Science, 2016-08)
The aim of this work was to study the long-lasting consequences of different weaning age on physiological, immunological and microbiological parameters of weaned piglets. Piglets were weaned at 14 days (14W) or 21 days ...
Fatores de Correção para Ganho de Peso Médio Diário no Período do Nascimento ao Desmame em Bovinos da Raça Nelore
(1999-01-01)
The objective of this work was to calculate correction factors for the effects of age of the dam (AOD), age of the calf (AOC) and Julian birth date (DOB) on the average daily gain (ADG) from birth to weaning period of ...
Comparison of selection criteria for pre-weaning growth traits of Nelore cattle
(Elsevier B.V., 2004-03-01)
Genetic parameters were estimated for pre-weaning average daily gain (ADG) and number of days to gain 160 kg from birth to weaning (D 160) of Nelore cattle. Ranks of animals were compared for these traits. Heritability ...
Growth performance and intestinal replacement time of 13C in newly weaned piglets supplemented with nucleotides or glutamic acid
(2019-09-01)
Dietary supplementation of nucleotides (NU) and glutamic acid (GA) have been suggested for post-weaned pigs because of their potential role as performance enhancers. During this phase, both additives may become essential ...
Fiber sources in diets for newly weaned piglets
(Sociedade Brasileira de Zootecnia, 2012-03-01)
