We investigated whether microalgae or linseed supply during the early postpartum period affects ovarian restimulation and supports the first postpartum ovulation in lactating anovulatory goats. Thirty-eight An-glo-Nubian-crossbred adult goats were allocated into three groups, one with a control diet ( = 12), fed a total mixed ration (TMR) comprising chopped elephant grass and concentrate; an algal diet ( = 13), fed TMR + green microalgae (1% dry matter); and a linseed diet ( = 13), TMR + linseed (12% dry matter). Supplements were furnished from the second to fifth week (time of weaning).

Monosodium glutamate (MSG), a widely used food additive, has been associated with various health concerns, including potential reproductive toxicity. This study investigated the protective effects of black garlic (BG) ethanol extract against MSG-induced ovarian damage in rats. Thirty-two female rats in estrus were randomly divided into four groups ( = 8 per group): control (saline), BG (250 mg/kg BW), MSG (4 mg/g BW), and BG+MSG (combined treatment).

This study compared the reproductive performance of three different programs using conventional fixed-time artificial insemination (FTAI), fixed-time embryo transfer (FTET), and their combined use, considering estrus intensity as a criterion for the reproductive program. Brangus multiparous cows (n = 1.100), 40-50 days postpartum, 4-8 years old, and body condition scores 2.

This study aims to explore the effects of Yin and Yang Double Supplement Compound Chinese Medicine Preparations (YYSBFF) on the reproductive performance, antioxidant levels, and immunity of dairy goats. For the experiment, 36 Alps milk goats were selected and randomly divided into an experimental group and a control group, with 18 goats in each group. The ewes in the experimental group were fed with YYSBFF for 14 d prior to breeding and farrowing.

In mice, naturally occurring and induced mutations in the suppressor of cytokine signaling-2 () gene are associated with a high growth phenotype characterized by rapid post-weaning weight gain and 30-50% heavier mature body weight. In this work, we demonstrate an electroporation-based method of producing knock-out (KO) sheep. Electroporation of dual-guide CRISPR-Cas9 ribonucleoprotein complexes targeting was performed 6 h post-fertilization in sheep zygotes.
