Abstract: This study aimed to verify the reproductive seasonality in Saanen goats from distinct parity orders (nulliparous, primiparous, and pluriparous) throughout an entire year in the Southeast Region of Brazil. In addition, it was also verified the influence of environmental indexes, metabolic profile, body weight, and social interactions on the reproductive seasonality of these animals. Forty Saanen goats kept under intensive system at latitude 22° 52' 30? s and tropical photoperiod (11-13 h of light per day) were used. Every 15 days, blood from 24 animals (8 animals per group) was collected for assessment of serum progesterone levels. Monthly, environmental data (rainfall index, maximum and minimum temperature, and time of natural daylight) and blood were collected to evaluate the metabolic profile. Weighting and body condition score measurement were also carried out every 2 months. There was no difference in body weight and body condition score in primiparous and pluriparous goats. Nulliparous goats showed natural breeding season in the winter season while the primiparous and pluriparous goats remained cyclical in autumn and winter season. Regardless of the parity order, all goats showed a seasonal anestrus in the spring season. From December, social interactions were able to reestablish, in distinct degrees, the cyclical state in the goats. Likewise, environmental and weight indexes had low and moderate influence, respectively, on the reproductive seasonality in the Saanen goats kept under tropical conditions.

Free bioactive amines were quantified during germination of tannin and tannin-free sorghum seeds (8 genotypes) and seedlings (2 genotypes). Among the ten amines investigated, three (putrescine, spermidine and spermine) were found. Tannin-free sorghum seeds had higher levels of spermidine, spermine, putrescine and total amines (1.28, 1.27, 0.35, 2.91 mg/100 g dwb, respectively), compared to tannin sorghum (0.91, 1.13, 0.06, 2.09 mg/100 g dwb, respectively). Throughout germination, in all seedling parts, putrescine was prevalent followed by spermidine. Spermine was only detected in the 7th germination day in the cotyledon and radicle of tannin sorghum. In the cotyledon, putrescine levels increased (24- and 30- fold for tannin and tannin-free sorghum, respectively). Spermine decreased, but it increased reaching initial levels (~1 mg/100 g dwb) in two tannin-free genotypes. Spermidine changes were not significant. Germinated sorghum was characterized by high putrescine and low spermidine levels, with higher levels for tannin-free (29.55 mg/100 g putrescine; 2.79 mg/100 g spermidine) compared to tannin (24.41 mg/100 g putrescine, 1.40 mg/100 g spermidine) sorghums. Different from other seeds, germinated sorghum is rich in putrescine. By selecting the proper genotype one can modulate polyamine contents in germinated sorghum, thereby obtaining different profile of amines for specific food application. |
