“…Reproductive traits are known to play an important role in the productive performance of pigs (Li et al 2017b;Bovula et al 2021;Ma et al 2022). Published literature indicates that FSHβ is directly linked to reproductive performance (Zhao et al 1998;Li et al 2017a;Ye et al 2018;Petrovas et al 2020;Morton et al 2023).…”

FSHβ plays an important role in the reproductive performance of pigs, but there are no studies on its protein structure and function. In this study, bioinformatics tools were used to predict the physicochemical properties, secondary and tertiary structure, hydrophobicity/hydrophilicity, transmembrane domain, and sites of phosphorylation and glycosylation of signal peptide FSHβ protein of sows. The results showed that the number of amino acids of FSHβ was 185, that is, the theoretical isoelectric amino acid point was 53.8, the instability index was 46.23, and the average hydrophilicity coefficient was 0.732. FSHβ protein was found to be a hydrophobic protein without a transmembrane domain, with 33 phosphorylation sites. None of the signal peptides was found to be distributed in the inner complete sequence. The secondary structure was mainly composed of α-helix, extended strand, β-turn, and random coil, with values of 29.97, 27.53, 10.10 and 32.40%, respectively. In summary, this study suggests that the amino acid sequence (988~1146aa) of FSHβ can be used to express antigens. It provides a reliable basis for further study of FSHβ protein function, purification of FSHβ protein, preparation of FSHβ antibody, and drug screening to improve reproductive performance of pigs.

“…Amao and Showunmi [27] reported that bucks fed on raw cottonseed cake -based diet had significantly higher values for left, right and mean epididymal weights than for bucks on other fermented cottonseed cake. Epididymis stores and transports spermatozoa that are produced in the testis of boars [50].…”

“…Testicular testosterone output is primarily regulated by the pulsatile pattern of pituitary LH secretion [51]. These androgenic properties enhance concentration of luteinizing hormone, which is responsible for testicular development such as epididymis and testicular weight [50]. An increase in epididymis weight could be is associated with quadratic increase in semen volume.…”

The study aimed to evaluate testicular size, weight and epididymal semen quality of Large White × Landrace (LW × LR) boars fed fermented liquid potato hash. Diets containing either 200 (LFLPH) g/kg potato hash; 400 (HFLPH) g/kg potato hash or no fermented potato hash (control). Forty-two crossbred boars (LW × LR) weighing (25 ± 2.3 kg) were individually housed and fed ad-lib one of the seven dietary treatments for three months. Pigs were allocated to diets in complete randomized design. After 3 months and 600 ± 4 kg average body weight boars were slaughtered and epididymal semen was collected from head of epididymis. Boars that were fed control had higher (P < 0.05) live spermatozoa concentration than LLFPH and HFLPH diets. However, HLFPH had higher (P < 0.05) proximal droplet, distal droplet and dead spermatozoa concentration than control and LLFLPH. In addition, boars that were fed control and LLFPH had higher (P < 0.05) total, progressive, rapid motility, and lower non-progressive, static, medium and slow motility than HLFPH. It is concluded that low liquid fermented potato hash diet could be used as an alternative feed source for pigs. The results indicated that diets contain LFLPH can be used in boar diets without any adverse effects on spermatozoa quality.

“…This breed present characteristics not found in more productive and selected commercial breeds, such as adaptation to environmental conditions, good maternal qualities, longevity, and disease resistance which is a great interest in a world facing environmental challenges (Hlongwane et al, 2020). Their unique characteristics make them important genetic resources, which can be conserved (in or ex-situ) during this current era of climate change (Marsoner et al, 2018;Bovula et al, 2021). Therefore, population of indigenous pigs is, considered stagnated due to the absence of a comprehensive improvement and conservation strategy (Roberts and Lamberson, 2015).…”

The domestic pig breeds are in danger of extinction whereas the erosion of their gene pool is a serious concern because they significantly contribute to the rich biodiversity. Overall aim of this study was to determine the protocol for preserving the semen of the Windsnyer boars for conservation. A total of 18 ejaculates (6 replications/boar) were collected from three Windsnyer boars of proven fertility with the use of hand-gloved approach method, twice per week. Boars semen were pooled and extended with Beltsville Thawing Solution [(BTS) IMV Technologies, France], held at 18°C for 3 hours and centrifuged. The sperm pellet was re-suspended with Fraction A (20% egg yolk + BTS) and cooled at 5°C for 1 hour. Following cooling, semen was divided and diluted into different cryoprotectants (ethylene glycol, glycerol, propanediol, ethylene glycol + glycerol + propanediol) at equal contribution to make the total concentrations [4, 8, 12 and 16% and the 0% (control; without cryoprotectant)] and loaded into 0.25 mL straws. Two cryopreservation methods (liquid nitrogen vapour and controlled rated) were used to cryopreserve the semen straws. Semen straws were thawed at different temperatures (5, 18, 37 and 40°C) and evaluated for sperm motility, viability, and morphology traits. Post-thawed sperm total motility (36.0±5.3) and live normal sperm (49.5±8.3) percentages were recorded to be higher in the treatment supplemented with 16% glycerol (P<0.05). The highest sperm total motility percentage was recorded at 40°C (26.8±3.2) thawing temperature for liquid nitrogen vapour treatment (P<0.05). In conclusion, 16% glycerol was found to be the suitable cryoprotectant concentration for semen cryopreserved with liquid nitrogen vapour method and thawed at 40°C.
