Resumo:
Maternal nutrition is crucial for the development of metabolic patterns
and for the somatic growth of the conceptus. The consumption of lipid sources interferes
in the composition of fatty acids in breast milk, which affect development
in short and long term. The lipid fraction of breast milk represents the largest
source of energy and has an important role in the regulation of various processes
metabolic. The lack of this nutrient may be related to changes in the
growth, in the skin, in the immune and neurological systems. A lipid source
rich in essential fatty acids is chia ( Hispanic Salvia L.). Aimed with
this work analyze the influence of chia oil in rats, during the lactation period,
and its effects on the physical development of offspring. Females were used
primiparae, to obtain the offspring. The animals were divided into three groups:
Control group (CG) (n=15) - received oil-based laboratory standard
of soybeans, Group chia (GCH) (n=14) - received 95% of standard diet + 5% of oil.
chia, Lard group (GB) - received 95% standard diet + 5% lard.
The weight and length of the tail were recorded daily. the parameters
somatic measurements were: Auricular Pavilion Opening (APA), Opening of the
Auditory Conduit (ACA), Eye Opening (AO), Incisor Teeth Eruption
Upper Incisor Teeth (EIS), Eruption of Lower Incisor Teeth (EII) and Appearance of
By Epidermal (EPA). The results were analyzed through the program
Sigma Stat Software (3.1). For the analysis of the biological test data was applied
analysis of variance (ANOVA). Body weight was higher in the GB group compared to
to the GCH and GC groups from the r day and persisted until the end of lactation. Regarding
to the growth of the neonates' tail, on the 1st day, the lard group (GB) presented
greater evolution when compared to the group (GCH) and the group (CG) (P < 0.05), no
there was a statistical difference between the groups on the r, 14th and 21st day. As for the
indicators of somatic maturation, the results found showed difference
significant between the HCG group compared to the GB group for the anticipation of
Opening of the Ear Pavilion (APA) and in relation to Incisor Teeth Eruption
Inferiors (EII). Considering the results obtained, it is possible to conclude that the
chia oil supplementation in the lactation period contributed to acceleration
of some somatic parameters (APA and Ell). However, even having interfered with
positively in the aforementioned parameters, it was not able to promote acceleration in the
other physical parameters of the offspring.
