Energy Balances of Lactating Sows in Relation to Feeding Level and Stage of Lactation

Journal of Animal Science, 1985
Twelve crossbred sows were used in an energy balance study to estimate energetic efficiency of milk production from feed. Balances were made from 7 to 14 d and from 18 to 25 d of lactation. Two feeding levels were applied (high and low). The low level (L) was meant to supply energy slightly above maintenance, with energy needed for milk to be derived ...

Yield and composition of milk from lactating mares: effect of lactation stage and individual differences

Journal of Dairy Research, 1990
SummaryThe yields and composition of milk from nursing mares were studied during the first two months of lactation in 11 mares of heavy breeds (784 kg). Daily yield increased from 21·7 to 24·6 kg between weeks 1 and 8 of lactation. Fat, protein, gross energy and Ca concentrations significantly decreased when lactose content increased during this period.

Intermittent suckling enables estrus and pregnancy during lactation in sows: Effects of stage of lactation and lactation during early pregnancy

Theriogenology, 2009
Previously we demonstrated that pre-ovulatory LH and post-ovulatory progesterone (P4) concentrations in plasma were low and embryo development was retarded when sows were induced to ovulate during lactation by submitting them to intermittent suckling (IS).

Triacylglycerol Composition of Breast Milk during Different Lactation Stages

Journal of Agricultural and Food Chemistry, 2019
Triacylglycerol (TAG) composition of breast milk plays an important role in improving digestion, absorption, and metabolism when consumed by infants. This study characterized the TAG profile of human colostrum, transitional, and mature milk samples from 103 women.

Behaviour of lactating sows: Influence of stage of lactation and husbandry practices at weaning

Applied Animal Behaviour Science, 1989
Abstract The effects of stage of lactation, withholding of feed and weaning method on the behaviour of 12 primiparous sows, housed in farrowing crates, were studied. The sows were observed for 24 h on Days 17 and 27 of lactation as well as on the day of weaning (Day 28). Sows spent a greater proportion of time lying down during dark than during light

Effect of stage of lactation and gestation on milking-induced hormone release in lactating dairy cows

Domestic Animal Endocrinology, 2019
Three experiments were conducted to better understand why milking-induced prolactin (PRL) release decreases as lactation advances. Experiment 1 compared the effects of milking, 2-min manual stimulation of the mammary gland (without milking), or injection of 1 IU of oxytocin (without milking) on hormonal release in early lactation cows, late-lactation ...

Cheese-making capacity of goat's milk during lactation: influence of stage and number of lactations

Journal of the Science of Food and Agriculture, 1999
The effect of the stage and number of lactations on the technological properties and cheese-making capacity was studied in Murciano-Granadina goat's milk. Controls were done every month to evaluate the evolution of chemical composition and the values of the clotting properties which define the milk quality with regards to rennet curdling. The influence

Maximal Lactate Steady-State Prediction Through Quadratic Modeling of Selected Stages of the Lactate Minimum Test

Journal of Strength and Conditioning Research, 2008
In this study, we compared the maximal lactate steady state (MLSS) with lactate minimal (LM) intensities determined visually and through a quadratic polynomial function of selected stages of LM test. Eleven male recreational cyclists (27.7 +/- 4.5 years, 175.7 +/- 5.6 cm, 69.5 +/- 10.8 kg, and 12.0 +/- 5.5% body fat) performed one LM test under ...

Influence of Lactation Order and Lactation Stage on Physico-Chemical Properties of Pantja Goat Milk

Indian Journal of Animal Research, 2020
Goat is a versatile animal having short generation interval with lower investment cost and higher prolificacy. The present study was carried out at Goat farm, LPM, GBPUAT, Pantnagar. During the entire study the fresh milk samples of Pantja goats were taken according to lactation order and stage viz., 1st (Upto 30 days), 2nd (31 to 60 days) and 3rd ...

Total potentially available nucleosides of human milk by stage of lactation

The American Journal of Clinical Nutrition, 1995
Human milk-borne ribonucleotides reportedly have important physiological roles in breast-fed infants. Previous studies measured the free nucleotide content of human milk. To more fully evaluate the physiological capacity of nucleotides in human milk, we determined the monomeric and polymeric ribonucleotide and ribonucleoside content of milk pooled from
