Female ornaments are expected to evolve through sexual selection when male parental investment is high. Blue-footed boobies are socially monogamous seabirds with a long period of biparental care. Males and females have colourful feet that are displayed ostentatiously during courtship, both before and after pairing, and extrapair copulations are frequent. We manipulated the foot colour of paired...

BACKGROUND: Cardiac Troponin I (cTnI) is known as a cardiac biomarker in determining the myocardial damage of diseases which affect the heart muscle. OBJECTIVES: This study aims to evaluate the serum cTnI concentration in Markhoz Breed goats suffering selenium (Se) deficiency and its correlation with electrocardiographic parameters, and activity of creatine kinase (CK) and aspartate aminotransf...

Morphometric, metabolic, and behavioral modifications were studied in goat kids after maternal feed restriction during the last one-third of pregnancy. At birth, only kids from twin and triplet litters were studied [n=40 kids born to control dams (CONT) and n=38 born to restricted dams (REST)] and only males thereafter (n=13 CONT and 15 REST kids) until slaughter at 6 wk of age. Kids born to re...

On farm monitoring of central highland goats were conducted in Sekota district of the Amhara regional state, Ethiopia to evaluate the growth performances under the traditional management practices. On farm feeding trial was also conducted to see the feeding performances and carcass characteristics of Central Highland goat types. Data used for the study was collected from randomly selected on-fa...

The aim of the study was to determine the effect of the type of birth, the sex of the kids, the duration of the birth (categorized as short, medium, or long), and the level of maternal care (categorized as low, medium, or high) on the behavioral variables of kids during the first hour after birth. The parturitions of 78 primiparous goats of Murciano-Granadina breed (46 single-birth and 32 twin-...

searching the content for the kids is different from searching for adults. The needs of the kids are different and the way they search the content on the web is also different. There are a lot of issues that needs to be taken care of while searching for the kids. Our aim in this paper is to develop an interface that can help parents, teachers and kids to search the web in a secure way and make ...

Investigations were conducted on one group of White Improved (WI) kids and three groups of WI crossbred kids with various share of the Boer (B) genes: 1/4B3/4WI, 1/2B1/2WI and 3/4B1/4WI. Eighteen male kids were included in each group. Up to 20 kg life weight the kids of all groups had free access to their dams’ milk and to solid feed from day 14 of life. Crossbreds with 25, 50 and 75% of the B ...

The growing interest in reducing methane (CH4) emissions from ruminants by dietary means is constrained by the complexity of the microbial community in the rumen of the adult animal. The aim of this work was to study whether intervention in early life of goat kids has an impact on methane emissions and the microbial ecosystem in the rumen and whether the effects persist postweaning. Sixteen doe...

The effect of maize grain supplementation on the resilience and resistance of browsing Criollo goat kids against gastrointestinal nematodes was evaluated. Five-month-old kids (n = 42), raised worm-free, were allocated to five groups: infected + not supplemented (I-NS; n = 10), infected + maize supplement at 108 g/d (I-S108; n = 8), maize supplement at 1% of body weight (BW) (I-S1%; n = 8), maiz...
