ORIGINAL ARTICLE: Effects of dietary glucose inclusion on reproductive performance, milk compositions and blood profiles in lactating sows

Abstract

Twenty-four multiparous sows were used to investigate the effects of dietary glucose inclusion on reproductive performance, milk compositions, blood metabolites and hormones during lactation. The sows were randomly assigned to four treatments and each treatment had six replicates (sows). The diets were added with 0%, 1%, 3% or 5% glucose at the expense of corn and fed to sows for 24 days. The loss of backfat thickness during lactation was quadratically decreased (p = 0.008) and the wean-to-oestrus interval was shortened (linear, p = 0.013; quadratic, p = 0.009) with increasing levels of dietary glucose supplementation. The reproductive performance was not affected (p > 0.05) by different dietary glucose contents. Increased concentrations of total solid and fat in milk were noted (p < 0.05), whereas there was no difference on colostrum compositions. With increasing levels of dietary glucose inclusion, the concentrations of blood urea nitrogen (p = 0.004) and glucose (p = 0.029) were linearly increased at weaning. The concentrations of insulin were increased at post-farrowing (linear, p = 0.027; quadratic p = 0.013) and weaning (linear, p = 0.029; quadratic, p = 0.017), respectively. Furthermore, the pulses of insulin and FSH at weaning were linearly (p = 0.049) and quadratically (p = 0.015) increased with the increasing levels of dietary glucose inclusion. In conclusion, this study indicated that inclusion of 3% glucose in lactating diet could reduce backfat loss, increase milk fat and have no negative effect on reproductive performance in multiparous sows.

Effects of dietary resistant starch content on metabolic status, milk composition, and microbial profiling in lactating sows and on offspring performance

“…Milk samples (50 ml) were obtained from each sow on day 10 after farrowing by manually milking the third and fourth anterior mammary glands on 1 side of the sow as previously described (Park et al., ). All sows were milked at the same time in the morning, 2 h after feeding, (Park et al., ) and at the initiation of a suckling period by pigs (Rincker et al., ). Samples were immediately frozen at −20 °C for subsequent analyses.…”

Comparison of serum leptin, glucose, total cholesterol and total protein levels in fertile and repeat breeder cows

“…Blood glucose, cholesterol and protein appear to be some of the R. Bras. Zootec., 43(12):643-647, 2014 key nutrients affecting fertility and cyclicity in farm animals (Qureshi, 1998;Park et al, 2010). Therefore, the present study was designed, firstly, to compare circulatory levels of leptin, glucose, total cholesterol and total protein in repeat breeder and fertile cows.…”

Histomorphology of seminal vesicle and testicular tissue of Wistar rats following administration of Carica Papaya

“…Different types of serum and testis specific proteins (somatomedin C, sulfated glycoproteins 1 and 2, ceruloplasmin, transferrin, androgenbinding protein, Sertoli-derived growth factors, Müllerian-inhibiting substance, cyclic proteins-2 and inhibin) are secreted by Sertoli cells, although the functions of some of these proteins are poorly understood (National Cancer Council, 1989). Proteins appear to be one of the key nutrients affecting productive cycle and fertility in animals (Park et al, 2010). Studies have used proteins in plasma or serum in predicting endometrial function (Joshin, 1986).…”
