2. Effect of Artemisia apiacea Hance on growth performance, cecal opportunistic bacteria, and microbicidal peptides in rabbits
ABSTRACT This study aimed to investigate the effect of Artemisia apiacea Hance supplementation on growth performance, cecal opportunistic bacteria, and antimicrobial defense using 120 rabbits. There were four experimental diets containing a control and A. apiacea Hance added at doses of 25, 50, and 75 g kg−1 of feed. The trial lasted for 70 days. The resul

3. Red clover silage: an alternative for mitigating the impact of nitrogen excretion in ovine production systems
ABSTRACT The objective was to quantify the flow of intestinal nutrients and nitrogen excretion and retention in sheep receiving isoproteic diets. Eight Texel x Lacaune wethers (average body weight = 25±2.5 kg) were fitted with duodenal cannula and housed in metabolic cages. Wethers were assigned to the treatments in a crossover design with two periods of 20

4. Evaluation of an herbal choline feed plant additive in lamb feedlot rations
ABSTRACT An experiment was carried out to evaluate the effect of an herbal choline feed plant additive on the productive parameters and blood metabolites of finishing lambs. Forty male Hampshire × Suffolk lambs (initial body weight of 30.36±3.75 kg) were assigned according to a completely randomized design. Treatments consisted of dietary inclusion of the

5. Effect of Feed Restriction and Photoperiod on Reproduction and LEPR, MELR mRNA Expression of Layers
ABSTRACT Photoperiod and nutrition are major factors that affect the reproductive efficiency particularly in female animals. In this study we examined the interaction of photoperiod and food restriction on growth, sexual maturation and receptor mRNA expressions of leptin, melatonin, and estrogen in abdominal fat and the ovary of pullets. There were no intera

6. Comportamento ingestivo de cordeiros Santa Inês alimentados com resíduo de cervejaria desidratado
RESUMO Objetivou-se avaliar o comportamento ingestivo de cordeiros Santa Inês alimentados com resíduo de cervejaria desidratado (RCD). Foram utilizados 35 cordeiros, machos, não castrados, com peso médio inicial de 16,00±1,69kg e, aproximadamente, 70 dias de idade. Adotou-se o delineamento inteiramente ao acaso, com cinco tratamentos e sete repetições

7. PHOSPHORUS REQUIREMENT OF TAMBAQUI FINGERLINGS
RESUMO Objetivou-se determinar a exigência de fósforo digestível em rações para alevinos de tambaqui (Colossoma macropomum). Utilizou-se 900 alevinos (0,51 ± 0,06 g), em delineamento inteiramente casualizado, com seis tratamentos, cinco repetições, e trinta peixes por unidade experimental. Os tratamentos constituíram-se de seis rações com diferent

8. Assessing the implications of mycotoxins on productive efficiency of broilers and growing pigs
ABSTRACT: The effects of mycotoxins on the productive performance of growing pigs and broilers were evaluated using meta-analytical approach. Two databases were constructed: (1) Broilers, with information collected from 51,497 birds and published in 158 scientific papers from 1980 to 2016; and (2) Pigs, with information collected from 7,743 animals and publi

9. Effects of Dietary Brewery Spent Grain Inclusion on Egg Laying Performance and Quality Parameters of Bovans Brown Chickens
ABSTRACT Poultry rations are composed mainly of conventional cereal grains and proteins. Using non-conventional agro-industrial by-products may reduce the cost of production and thereby improve productivity. A study was conducted to evaluate the effect of dietary brewery spent grain inclusion on egg laying performance, quality parameters of bovans brown and

11. Effect of feeding heat-treated and unheated colostrum on immunoglobulin G absorption, health and performance of neonatal Holstein dairy calves
ABSTRACT. First colostrum is an important source of nutrients and immune factors which are necessary for calves in the first weeks of life. Despite these benefits, colostrum can also represent one of the earliest potential exposures of dairy calves to infectious agents which these patogens can act directly on growth and cause diseases such as scours or septi

12. PERTINENCE CURVES IN FUZZY MODELING OF THE PRODUCTIVE RESPONSES OF BROILERS
ABSTRACT The selection of the type of fuzzy systems pertinence curve allows a better representation of the mathematical model and a smaller simulation error. We aimed to study the effect of pertinence curves in fuzzy modeling of broiler performance, created in different production systems. For the development and testing of fuzzy models, three commercial avi
