Evaluation of Some Litter Traits and Heritability Estimates of Nigerian Indigenous Pigs [PDF]
Cumulative litter records of 1494 progeny from 257 litters produced by 30 sires and 87 sows of Nigerian indigenous pigs (NIP) from the Swine Unit of Obafemi Awolowo University Teaching and Research Farm for a period of fourteen years (1977-1990) were ...

PSMA8‐Containing 20S Proteasome Regulates Spermiogenesis and Male Fertility
PSMA8 assembles s20S proteasome that degrades specific substrates in elongating spermatids. Degradation of s20S‐substrates activates translation of FXR1‐target mRNAs, which are essential for mitochondrial sheath formation and sperm morphogenesis.

No evidence for a trade-off between reproductive investment and immunity in a rodent. [PDF]
Life history theory assumes there are trade-offs between competing functions such as reproduction and immunity. Although well studied in birds, studies of the trade-offs between reproduction and immunity in small mammals are scarce.

Development of a new grading system to assess the foster performance of lactating sows
Increasing litter size has created the need for more sophisticated, accurate, and welfare-oriented systems for assessing the foster performance of lactating sows.

An evaluation of two grassland-based systems of mid-season prime lamb production using prolific ewes of two genotypes [PDF]
peer-reviewedA 4-year study was undertaken to evaluate the effects of two contrasting management systems [year-round grazing (YRG) and normal seasonal grazing followed by indoor feeding during winter (GWF)] on performance of mid-season lambing ewes. On

Impaired endometrial receptivity contributes to the poor pregnancy outcomes in women with PCOS. The authors found that decreased endometrial IL‐22 levels and disrupted STAT3‐IGFBP5 signaling pathway contributed to impaired endometrial receptivity. Supplementation with IL‐22 or IGFBP5 exerts a protective effect on implantation failure in PCOS‐like mice,

Epidemics on random intersection graphs [PDF]
In this paper we consider a model for the spread of a stochastic SIR (Susceptible $\to$ Infectious $\to$ Recovered) epidemic on a network of individuals described by a random intersection graph.

An activity‐dependent pathway links prefrontal circuit hypoactivity to cognitive impairment. Reduced PVA–mPFC activity upregulates NEPAS, which suppresses PTX3 secretion, leading to impaired angiogenesis, myelin deficits, and memory decline. Rescue is achieved by NEPAS knockdown or chemogenetic circuit activation.

Piglet mortality in organic herds [PDF]
Productive performance of organic pig farms is lower compared to conventional farms, but only very few data exist. Better knowledge of the productivity of organic herds regarding litter size at birth, piglet losses around birth and during lactation, as ...
