Semen collection and artificial insemination have not yet been fully developed in the alpaca. Thus, we collected semen from 7 males using a modified artificial vagina placed inside a dummy. Forty adult female alpacas, previously induced to ovulate with hCG, were artificially inseminated with fresh undiluted semen by laparoscopy or by cervix. The Chisquare(More)
Degelification of highly viscous alpaca semen was attempted using two enzymes: trypsin and collagenase. Dilution effect on artificial insemination was determined in alpacas. Semen from 4 male alpacas was collected, degelified, diluted, and inseminated into 80 female alpacas. Degelification was achieved adding trypsin and collagenase enzymes to fresh semen(More)
Semen characteristics of alpacas were studied after repeated collections. Twelve adult males were divided into three groups of four each for semen collection once, twice, or three times every other day. The duration of copulation; volume of ejaculate; pH; motility; sperm concentration (number of sperm/milliliter semen); total number of sperm per ejaculate;(More)

OBJECTIVE To determine concentrations of estrone sulfate in serum, estrone sulfate in urine, relaxin in serum, and progesterone in serum in pregnant llamas and alpacas and to assess the potential of these hormones as pregnancy indicators. DESIGN Prospective study. ANIMALS 19 parous pregnant camelids (8 llamas and 11 alpacas). PROCEDURE Estrone sulfate(More)
OBJECTIVE To evaluate use of fluprostenol, dexamethasone, and oxytocin for induction of parturition in alpacas, and to determine viability of the newborn crias. DESIGN Prospective, randomized, controlled trial. ANIMALS 36 pregnant alpacas within 10 days of parturition. PROCEDURE Animals were randomly assigned to treatment groups. Plasma progesterone(More)
The fertility of the male alpaca under different frequencies of daily consecutive matings was evaluated. Fifteen adult male Huacaya alpacas were divided randomly into three groups of five each to breed lactating female alpacas. The schedule of daily matings was two, four and six consecutive breeding per group and for nine consecutive days. Ovulation was(More)

In December 2010, 58 people from 18 countries attended a Salzburg Global Seminar to consider the role patients can and should play in healthcare decisions. Those listed below have agreed a statement that calls on patients and clinicians to work together to be co-producers of health. We call on clinicians to: · Recognise that they have an ethical imperative(More)
BACKGROUND Increasing patient engagement in healthcare has become a health policy priority. However, there has been concern that promoting supported shared decision-making could increase health inequalities. OBJECTIVE To evaluate the impact of SDM interventions on disadvantaged groups and health inequalities. DESIGN Systematic review and meta-analysis(More)
