Effect of Replacing Sorghum Stubble with (L.) on Liveweight Change, Blood Metabolites, and Hematic Biometry of Goats.

Tillandsia recurvata is an epiphyte that grows on the canopy of many trees in tropical and subtropical areas of America. The objective of this study was to evaluate the effect of partial or complete substitution of sorghum stubble with T. recurvata on liveweight change, metabolic profile, and complete blood count of goats fed increasing levels (0, 30, and 60%, dry matter basis) of T.

Body condition and stage of seasonal anestrus interact to determine the ovulatory response after male biostimulation in anovulatory Criollo × Nubian goats.

The effect of goat nutritional condition on the response to biostimulation with sexually active males during different stages of anestrus was determined. Fifty-eight Criollo × Nubian females on high and low body mass index (BMI) diets were used. Each BMI group was divided into two for biostimulation with sexually active males during May (mid-anestrus) or July (transition period).

Vitamin E supplementation of undernourished ewes pre- and post-lambing reduces weight loss of ewes and increases weight of lambs.

The aim of this study was to test if vitamin E supplementation during late gestation and early lactation would affect the weight of ewes under nutritional restriction and the performance of their lambs. Mature Rambouillet ewes (n = 37) were fed a diet that supplied 70 % of the energy and 80 % of recommended protein requirements and randomly assigned to either vitamin E (vit E, n = 20, 4 IU of α-tocopherol kg(-1) of live weight) or control (n = 17, without vitamin E supplementation). During the experimental period, the mean weight of ewes decreased from 74.

Relative roles of photoperiodic and nutritional cues in modulating ovarian activity in goats.

The objective of the current study was to evaluate the influence of nutrition and its interaction with the photoperiod on the ovarian activity of Criollo goats. In early February (22 degrees NL, anestrous season) goats were randomly assigned to the two experimental groups: high (HN; n=10) and low (LN; n=10) nutrition goats. The HN group was fed in mixed prairies with grass and clover (17.

Nutritional status influences reproductive seasonality in Creole goats: 1. Ovarian activity during seasonal reproductive transitions.

The objective was to determine the effect of body energy stores, evaluated by a body mass index (BMI), and food intake (FI), on the length of the anovulatory period and ovarian activity during the seasonal reproductive transitions in Creole goats. Non-pregnant, non-lactating Creole goats (n=28) were fed to induce two different BMI conditions: Greater (GBMI; n=15), and Lesser (LBMI; n=13). Each BMI group was divided into two sub-groups, which were either feed restricted (FR) or non-feed restricted (NFR).
