![]() ![]() Blood samples were collected at d-15, 28, and 56. Thirty non-pregnant three-year-old, non-lactating, healthy mixed-breed goats, ten animals per treatment (T0, T30, and T60), were adapted to diets and facilities for 14 days (d-14). recurvata on liveweight change, metabolic profile, and complete blood count of goats fed increasing levels (0, 30, and 60%, dry matter basis) of T. The objective of this study was to evaluate the effect of partial or complete substitution of sorghum stubble with T. Tillandsia recurvata is an epiphyte that grows on the canopy of many trees in tropical and subtropical areas of America. The male effect seems to be enough to induce oestrus during the late anoestrous season, irrespective of BCS and BW. 150% of the nutritional requirements), suggesting a high physiological plasticityīetween the groups, stabilising their metabolism according to the nutritional history female goats faced, and generating similar reproductive outcomes. Does demonstrated similar metabolic hormones and concentrations of blood metabolites between the two nutritional treatments (100 v. The increased nutritional level of the T-150 group during the anoestrous season did not result in an early onset of ovulatory activity. OnDay 12, all does exposed to males (16/16), irrespective of the nutritional treatment, depicted ovulatory activity, whereas only 3/16 (18.75%) T-WOM does did, indicating a significant (P < 0.001) difference between these treatment groups. To evaluate ovarian activity, blood samples were collected from all does on Days 2–4 during the 14-day period after the male exposure. Thereafter, in early August, half of the does in each diet treatment were randomly selected for determining the response to the ‘male effect’ (WM), forming the following two treatment groups: (1) T-100-WM (n = 8), or (2) T-150-WM (n = 8) the remaining does formed two groups without male exposure(WOM),as follows: (3)T-100-WOM(n = 8) and (4)T-150-WOM (n = 8). Final BW and BCS favoured (P 0.05) between the experimental groups. Blood samples were collected to analyse thyroxine (T4), triiodothyronine (T3), non-esterified fatty acids (NEFA), triglycerides (Tg) and progesterone (P4). Spanish, n = 32) were assigned to receive one of the following two experimental diets to fulfill different allowances of nutritional requirements: (1) 100% (n = 16 BW = 52.3 � 1.5 kg, BCS = 1.6 � 0.1 units T-100) or (2)150%(n =16 BW=60.9�2.4 kg,BCS= 1.6�0.1 units T-150) from February to August.The present study evaluated possible modulation of the buck effect by nutritional and metabolic cues during the transition to the breeding season in adult goats with divergent bodyweight (BW) and body condition (BCS) at 27�N. ![]()
