Effects of feeding level and diet composition on mammary growth in prepubertal lambs and mice
… percentage of total fatty acids in group S. Feeding the protected fat supplement resulted in increased unsaturated fatty acid, especially linoleic acid, percentage in mammary fat. This effect was associated with increased mammary growth compared to lambs fed a standard ration. Lambs treated …

Adipogenesis and fibrogenesis in muscle and effects of pregnancy and feeding level on carcass meat quality and development of cattle fetus
O presente trabalho foi desenvolvido a partir de três experimentos.O Objetivo do primeiro estudo foi de avaliar a deposição de tecido adiposo intramuscular e colágeno em músculo esquelético de animais da raça Wagyu em comparação com animais da raça Angus. Os animais foram manejados sob mesmas …

The Role of Insulin-like Growth Factor-I and IGF-binding Proteins in Mammary Gland Development
… strongly inhibited this growth response. High feeding level tended to increase IGFBP-3 levels in mammary tissue and reduced by 30% the growth response to mammary tissue extracts. Somatotropin increased the mitogenic response to mammary extracts at high feeding level and increased the tissue …

Differential gestation feeding levels on sow and litter performance, nutrient digestibility and energy homeostasis
… to determine the effects of differential feeding levels during gestation on sow and litter performance, nutrient digestibility and energy homeostasis. In Exp. 1, a total of 160 multiparous sows were allotted to 1 of 4 dietary treatments using a randomized complete block design with BW (BW) …

An investigation of the pathway of nitrogen incorporation into the leaf and root metabolism of Helianthus annuus L
… annuus fed at 50 µg N cm and 300 ~g N cm feeding level was analysed for nitrate, ammonia, and amino compounds. Nitrate accounted for 771to 94% of the total nitrogen transported via the xylem stream. The pathway of nitrate-N assimilation into amino compounds by the leaves and roots of …

Effects of pasture silage on yield and composition of milk from dairy cows
… were reviewed and it was concluded that feeding level and diet type (notably unwilted pasture silage) may have independent effects on yield and composition of milk. The objective of this research was to investigate the separate effects of forage type and feeding level on milk yield and …

The pathway of nitrogen assimilation in Datura stramonium L
… roots of Datura stramonium at different nitrate feeding levels has been investigated using 15N tracer experimentation, enzyme inhibitor studies and enzymological assays. Leaves were fed via their xylem stream with potassium nitrate at -1 -1 two concentration levels: 200 pg. N. ml and 25 JJ8 N. ml …

Effects of varying energy intakes on mammary growth and development in prepubertal heifers
… to 1 of 4 treatments (HH, HL, LH, and LL) with 2 levels of energy intake (High or Low) and 2 periods of growth (2 to 8 and 8 to 14 wk of age). At 14 wk, parenchyma at the stromal interface, mid-gland, and above the cistern were collected, fixed, and embedded in paraffin. Digital images of stained …

Effects of restricted feeding schedule during development and gestation on gilt and sow performance
… these experiments was to develop management and feeding programs to increase sow longevity and productivity by improving welfare conditions. In Exp. 1, 208 gestating sows and 288 gestating gilts were utilized to determine the effect of feeding frequency (2 vs. 6) on performance and welfare …

Investigating the influence of dietary fiber source and multicarbohydrase supplementation on digestibility, energy, systemic health, water balance, and gut motility in gestating sows
… were fed from d 28 to 109 of gestation at a feeding level of 2.1 kg (SID-Lys 11 g/d and 4.5 NE-Mcal/d). Two separate 9-d metabolism periods were conducted on d 50 to 59 (mid) and 99 to 108 (late) of gestation where serum and plasma were collected via jugular venipuncture. During each period, …

Effects of maturation, polyploidy, and nutrition on growth, composition, and gene expression within fatty acid metabolism in rainbow trout
… these variables. In the first study, effects of feeding level and polyploidy on fatty acid composition and metabolism of energy stores were considered. This study showed that ploidy had greater impact on fatty acid metabolism and composition of energy stores than moderately restricted diets at …
