Protein metabolism in the lactating sow
… intake and protein metabolism in the lactating sow. The primiparous sow exhibits poor appetite during the initial phase of lactation in relation to her requirements for production. The early phase of lactation is associated with a high plasma tryptophan to branched-chain amino acid (BCAA) ratio. …

Sow and piglet blood glucose levels over the farrowing period and relationships with sow and litter parameters
Low blood glucose levels in sows at the start of farrowing have been associated with increased farrowing duration and higher stillbirth rates and low blood glucose levels in piglets at birth have been linked to increased pre-weaning mortality. This study used 32 sows and gilts and 443 piglets in a …

Managing the lactating sow to stimulate lactation ovulation
In lactation, sows are typically anoestrus, with ovulation occurring three to seven days after weaning at approximately 24 days post-partum. Increasing piglet age to greater than 28 days improves piglet performance and welfare; however, it also results in reduced sow farrowing frequencies, making …

Design of the sow feeder: A systems approach
… was used to study the design of feeders for sows. This included: (1) the evaluation of commercially available feeder designs; (2) a survey of sows' head, front torso, and gross body dimensions; (3) a description of the kinematics of eating in sows; and (4) the design and evaluation of …

The Effect of Exercise on Lactating Sow Performance
… weaning wt (WW), and back fat (BF) of lactating sows housed in farrowing crates. A total of 24 sows were used in four trials. Body weight (BW), BF, BCS, SS, IS, and LS were recorded at placement into the farrowing barn and again at weaning. A scale of 1 (poor) to 5 (excellent) was used for BCS, …

Burn and Sow: The Ethical Implications of Ecological Restoration
Ecological restoration is quickly becoming a major approach to how humans interact with the natural world. Some view restoration as another land management technique on par with conservation and preservation. Others view it as a way to make reparations for our misdeeds and to reincorporate humans …

INVESTIGATING PIGLET CRUSHING BY THE SOW: A DATA MINING APPROACH
… crates provide a little more flexibility to the sows to communicate better with their litters, as well as to perform more exercise, posture changes, and more natural behaviors during lactation. A major concern with the alternative farrowing systems is the higher pre-wean mortality, especially due …

Influence of Nutritional Modifications on Sow, Litter, and Nursery Performance
… immune parameters.</p> <p>In the first study 99 sows were provided a control diet, or the control diet supplemented with 1% L-arginine from gestation d 93 to 110. Compared to control-fed sows, no differences were observed in reproductive parameters, however a tendency for increased gestational …

Environmental and Physiological Aspects of Prepartum Behavior in the Sow
… factors involved in the prepartum behavior of sows. Eight of 12 penned sows offered 3 kg straw from a wire basket took substantial amounts of straw and used it to construct farrowing nests during the 24 hours preceding birth of first piglet. Most activity was directed at straw and was much the …

Dynamics of energy and protein metabolism in the reproducing sow
… energy and protein stores after weaning. Sows with inadequate energy intakes during lactation exhibited greater weight loss, lower P$\sb2$ backfat depth and leaf fat weight at the end of a 28 d lactation. In the subsequent 35 d postweaning period, the low-energy fed sows retained only …

Reaping What You Sow: Southern Cultures, Black Traditions, and Black Women
This is an inquiry into Southern cultures, Black traditions, and Black women with a focus on the life of one Black woman educator. Drawing upon the works of Nobel Prize and Pulitzer Prize-winning African American woman, novelist, and master storyteller, Toni Morrison (1970, 1973, 1976, 1987, 1988, …

The Effects of Dry Sow Housing Conditions on Welfare at Farrowing
… to assess the effects of confined and loose dry sow and farrowing housing systems on the welfare of the sow and her litter. Litter size decreased and piglet mortality increased greatly after the sixth parity, regardless of housing system, resulting in a sharp decline in the number of piglets …

Investigating the effects of free lactation crates on sow and piglet welfare

This study compared the welfare of sows and piglets housed in two types of farrowing accommodation, free lactation …
