1. Screening, diagnosis and management of hypothyroidism in pregnancy: Number 10 – October 2022
Key points Pregnancy places a metabolic overload on the maternal thyroid, especially in the first trimester, mainly because of the demand imposed by the conceptus. The fetal thyroid becomes functionally mature only around pregnancy week 20. Until then, the fetus depends on the transfer of maternal thyroid hormones (THs). Thyroid hormones are essential for

3. Effect of Different Dietary Threonine Levels on Optimal Growth Performance and Intestinal Morphology in 1-14 Days Old Ross 308 Broilers
SUMMARY This experiment was carried out to evaluate the effects of four levels of dietary threonine (Thr) supplementations on growth performance, gut size and histomorphometric alterations of small intestines in broiler chicks in 1-14 days. Two hundred eighty-eight Ross 308 one-day-old male broiler chicks were randomly assigned to four treatments with six re

4. EFFECTS OF DIETARY FERMENTED GARLIC ON THE GROWTH PERFORMANCE, RELATIVE ORGAN WEIGHTS, INTESTINAL MORPHOLOGY, CECAL MICROFLORA AND SERUM CHARACTERISTICS OF BROILER CHICKENS
ABSTRACT The present study was conducted to evaluate the effects of feeding broilers with garlic fermented by Leuconostoc citreum SK2556. A total of 250 male broiler chicks was randomly housed into 25 floor pens. Five dietary treatments with five replicates of 10 chicks each (n=50 chicks/treatment). A corn and soybean meal based diet was used as the control

5. Growth performance, intestinal morphology, and meat quality in relation to alpha-lipoic acid associated with vitamin C and E in broiler chickens under tropical conditions
ABSTRACT This study was conducted to examine the effect of alpha-lipoic acid with vitamin C and E on growth performance, intestinal morphology, and meat quality in broiler chickens under tropical conditions. A total of 288 one-day-old male ROSS 308 chicks (40±0.1 g) were used in a completely randomized design and allotted to one of six dietary treatments to

6. Slow-release urea in diets for lactating crossbred cows
The objective of this study was to evaluate the performance of F1 (Holstein × Zebu) cows in lactation according to different levels of substitution of soybean meal for a protein equivalent non-protein nitrogen originated from slow-release urea (SRU). Eight F1 (Holstein × Zebu) cows in the first third of lactation, with an average milk yield of 12.7 kg (±3

7. Effects of dietary clinoptilolite and calcium levels on uric acid and calcium blood concentrations and bone quality of commercial layers
The objective of the present study was to evaluate the effect of clinoptilolite and calcium levels on uric acid and calcium blood profile and bone quality of commercial layers. A total of 576 birds were distributed according to a completely randomized experimental design in a 3x4 factorial arrangement (calcium levels of 2.5, 3.1, or 3.7% and clinoptilolite l

8. Perimicrovillar membrane assembly: the fate of phospholipids synthesised by the midgut of Rhodnius prolixus
In this study, we describe the fate of fatty acids that are incorporated from the lumen by the posterior midgut epithelium of Rhodnius prolixus and the biosynthesis of lipids. We also demonstrate that neutral lipids (NL) are transferred to the haemolymphatic lipophorin (Lp) and that phospholipids remain in the tissue in which they are organised into perimicr

9. Effect of tanniniferous plants and essential oils on methane emission in ruminants / Efeito de plantas taniníferas e óleos essenciais sobre a emissão de metano em ruminantes
Tannins and essential oils are secondary metabolites that may be used as natural modifiers of rumen fermentation to reduce the ruminants\ methane (CH4) emission. To study the application of tannin-rich plants from Egypt and Brazil, as well as essential oils that are available in international trade, three studies were conducted at Animal Nutrition Laboratory

12. Poultry viscera and bone meal in broiler pre-starter and starter diets
The use of viscera and bone meal in poultry pre-starter and starter diets and its effects on performance, digestive organ development and digestibility and nutrient retention were evaluated. In the first assay, 280-day-old Avian Cobb® chicks were allotted in four experimental groups with five replicates of 14 birds each, in the pre-starter phase; in the sec
