During lactation, sows need to eat a sufficient amount of feed to meet the requirements of milk production to nurture their litter and to sustain their body condition. Overall, information about feed intake of lactating sows is limited. In addition, information about other factors influencing feed intake of the sow may be incomplete. These factors include feeding strategy, lactation length, lit...

Sow performance is a key component of the productivity of commercial pig farms. Reproductive failure in the sow is common in pig production. For every 100 sows served, 89 should farrow. In absence of specific diseases such as porcine parvovirus, pseudo-rabies, swine fever, leptospirosis and brucellosis, management failures are the most important causes of loss. A syndrome associated with reprod...

this research was carried out to evaluate the effect of super-absorbent and manure on growth, yield, physiological and biochemical characteristics of geranium under deficit irrigation at research greenhouse of faculty of agriculture, lorestan university, iran, in 2014. the experiment was arranged factorially based on a completely randomized design with six replications. factor a was substrate c...

Mycobacterium (M.) bovis causes tuberculosis and has a broad host range, including humans, livestock, and wild animals. M. bovis infection of wild boar has been reported in several European countries. We report here the first case of M. bovis infection in a domesticated wild sow in Korea. Granulomatous and necrotizing lesions with small numbers of acid-fast bacilli were observed in nodules of t...

Quantum-chemical calculations were performed for all possible nine neutral tautomers of purine and their oxidized and reduced forms in water {PCM//DFT(B3LYP)/6-311+G(d,p)} and compared to those in the gas phase {DFT(B3LYP)/6-311+G(d,p)}. PCM hydration influences geometries, π-electron delocalization, and relative energies of purine tautomers in different ways. Generally, the harmonic oscillator...

For many breeding companies, performance testing in maternal lines is generally confined to traits such as average daily gain (ADG), back fat (BF) and perhaps loin muscle depth or area (LMD or LMA), along with litter size traits such as number born alive (NBA) or total born (TB). More sophisticated breeding programs will also accommodate traits associated with sow performance, longevity or pigl...

The way that sows are housed during gestation and lactation has moved towards more intensive systems so that sows can be more easily managed and production maximized. At a minimum, some of these factors have contributed to a decline in the productive life of sows in commercial pork production systems. A sow remaining in the breeding herd for fewer parities is likely to produce fewer pigs in her...

Abstract The optimum formulation in a surfactant–oil–water (SOW) system is defined as the physicochemical situation at which surfactant adsorbed interface exhibits exactly equal interactions for both oil and water. Identifying of SOW systems crucial various industrial applications, ranging from pharmaceuticals to cosmetics petroleum issues like dehydration enhanced recovery. Multiple techniques...

The objectives of this study were to characterize sows having high lifetime efficiency and high longevity (HE–HL), to examine the relationship between lifetime measurements, and to determine the association between the sows and herd productivity. This study was conducted by obtaining sow data with 66,262 parity records of 13,786 sows born during 1999 and herd data with mean measurements of 4-ye...

The objectives were to evaluate quantitative animal-based measures of sow welfare (lameness, oral stereotypies and reactivity to humans) under commercial farm conditions, and to estimate the influence of housing, sow parity and stage of gestation on the outcome of these measures. Across 10 farms, 311 sows were used. Farms differed in terms of housing design (pen v. stall), space allowance, floo...
