Porcine necrotic ear syndrome (PNES) in pigs has been reported as an increasing health problem in many countries with intensive pig farming. The etiology of this disease is complex and the presumed triggering factors can be divided into infectious and non-infectious agents. The present report describes a case of Porcine Circovirus type 2 (PCV2), infection associated with lesions of PNES at the ...

Retrospective data corresponding to the period between 2002 and 2018 were used, belonging Cooperativa Agropecuaria Integral San Juan de Yapacaní, Santa Cruz, Bolivia. Data 663 male female calves born primiparous multiparous cows used. The had 13 individual weight controls. Variables used: Date of birth, Calf live at birth in kg, weaning Average daily gain Live cow Number calving cows...

The milk/solid feed intake pattern and digestive capacity were compared in two groups of young rabbits reared between 16 and 32 days in litters of four (L4 group, n = 18 litters) or ten pups (L10, n = 20) in order to modulate milk availability. Compared to the L4 group, rabbits in the L10 group presented a lower milk intake (22.3 versus 28.8 g x day(-1)) and a higher solid feed intake (12.9 ver...

In a previous study, we showed that follicle size at weaning affects the response of a sow to a short-term altrenogest treatment after weaning. In this study, an attempt was made to prevent the growth of follicles into larger size categories before weaning by using different altrenogest treatments before weaning to improve reproductive performance after postweaning altrenogest treatments. Sows ...

Experiments were conducted to determine the effect of fumaric acid supplementation and buffering capacity of the diet on ileal and fecal digestibilities of CP, GE, and amino acids in early-weaned pigs. In two experiments, 12 pigs each were weaned at 14 d of age and fitted with a simple T-cannula at the distal ileum between 15 and 17 d of age. In both experiments, the pigs were fed four diets, b...

Background: Continuous positive airway pressure (CPAP) is used as respiratory support in preterm neonates; however, the best weaning method has not yet been determined. In this study, we compared sudden complete and gradual weaning from nasal CPAP (NCPAP) in preterm newborns. Methods: This randomized controlled trial was conducted on 62 prete...

This experiment was conducted to determine the effects of interval feeding of whole sunflower seeds on the performance of beef cows and their progeny. During mid to late gestation, 144 multiparous, spring-calving beef cows (588 kg of initial BW; 5.6 initial BCS; 4 to 13 yr old) were individually fed 1 of 3 supplements 4 d/wk for a 76-d period. Supplements (DM basis) included: 1) 0.68 kg of soyb...

The study investigates the effects of a post-weaning water restriction on performance, nutrient digestibility, carcass traits and meat quality of 84-day-old rabbits. A total of 1388 weaned rabbits (35 days) were randomly divided into two groups on the basis of BW and sex. The two groups were fed the same diets ad libitum both in the post-weaning (35 to 60 days) and fattening (61 to 84 days) per...
