Use of alternative diluent ACP-Lact® and coconut water powder (ACP) in cryopreservation of goat semen and fixed-time artificial insemination (FTAI) in half-breed goats.

The aim of the present study was to evaluate semen cryopreservation with ACP-Lact® diluent, which consists of coconut water powder (ACP) added to goat milk powder. After thawing, the samples were evaluated for sperm kinetics, membrane evaluation and insemination. For cryopreservation, a pool was made with the ejaculate of six goats, diluted in four equal aliquots for the respective treatments: T1 (ACP-Lact®); T2 (ACP-Lact® 50%); T3 (ACP + 2.

Effectiveness of near-infrared spectroscopy as a non-invasive tool to discriminate spectral profiles of cultured oocytes from goats.

Here, we aimed to discriminate between the spectral profiles of spent culture media after oocyte maturation (IVM) and culture (IVC) from goats of different ages subjected to repeated hormonal treatments. The profiles were discriminated using near infrared (NIR) spectroscopy combined with multivariate methods. A total of 19 goats (young = 10; old = 9) were subjected to serial hormonal stimulation (HS) with gonadotropins.

Impact of donor nutritional balance on the growth and development of mesenchymal stem cells from caprine umbilical cord Wharton´s jelly.

Mesenchymal stem cells (MSCs) from the umbilical cord (UC) have aroused considerable interest. However, little is known about the maternal effect on these cells. The aim of this study was to verify the impact of the nutritional status of donor goats on the growth and differentiation of MSCs from the UC.
