The effectiveness of supplementation programs is affected by the ability to reduce intake variation and to meet target supplement consumption. A review was made of factors affecting variation in individual animal consumption of supplement by grazing cattle and sheep, including supplement type and feeding method, animal dominance and social interactions, and forage availability. The effects of p...

T-2 toxin has been reported to cause severe oral lesions and neural disturbances in young broiler chickens. T-2 toxin, when added at a level of 20 mug per g of feed, caused oral lesions but no abnormal neural disturbances in young broiler chickens. T-2 toxin, when added at a level of 20 mug per g of feed, caused oral lesions but no abnormal neural symptoms in laying hens. T-2 toxin had no effec...

The present research was aimed to evaluate an interactive effect of cage density and level of dietary black cumin (BC) on productive efficiency of broiler chickens. A total of 270 broiler chickens (initial body weight of 163.12 ± 8.10g) were allocated into a completely randomized design with a 3 x 3 factorial pattern. The first factor was the cage density (bird/m2) namely, D1 = 8; D2 = 10, and ...

A study was conducted to determine the growth performance of Cobb broilers supplemented with varying concentrations of Moringa oleifera Aqueous Leaf Extract (MoALE) via the drinking water. A total of four hundred day-old chicks were randomly distributed into four treatment groups, replicated four times with twenty-five broilers per replicate. The growth performance of broilers was evaluated bas...

Channel catfish from two strains, USDA-103 and Norris, were reared in circular 800-l tanks Ž . and injected once weekly with 2.5 mg recombinant bovine growth hormone rbGH per gram body weight, or the saline vehicle. In addition to the rbGH, and strain treatments, half the tanks were supplied with well water of 26.08C and the other half received water of 21.78C. Growth rate, Ž . plasma insulin-l...

The following study was conducted to investigate the antibacterial and feed additive potential of medicinal plants. Ethanol extracts of different medicinal plants including Curcuma longa (Turmeric), Zingiber officinale (Ginger), Piper nigrum (Black Pepper), Cinnamomum cassia (Cinnamon), Thymus vulgaris (Thyme), Laurus nobilis (Bay leaf), and Syzgium aromaticum (Clove) were tested using the disc...

INTRODUTION AND OBJECTIVE Increased fructose consumption is associated with various metabolic changes that favor the onset of obesity and related comorbidities. The objective of this study was to assess the effects of chronic fructose consumption on body weight and adipose tissue, as well as on serum glucose and triglyceride levels. METHODS Thirty-day-old Wistar rats were divided into two gro...

The energy requirement of ewes increases during pregnancy. In late pregnancy, approximately 40% of the increase in heat production can be attributed to increases in heat production by nonreproductive tissues. The objective of this study was to determine the pattern of oxygen consumption by the portal-drained viscera (PDV) and liver during pregnancy to allow for an estimation of the extent to wh...

Increasing efficiency in livestock production and reducing the share of animal products in human consumption are two strategies to curb the adverse environmental impacts of the livestock sector. Here, we explore the room for sustainable livestock production by modelling the impacts and constraints of a third strategy in which livestock feed components that compete with direct human food crop pr...

−− The aim of this work is to simulate and analyze an extractive distillation process (extractive distillation and recovery columns) for the separation of Tetrahydrofuran (THF)-Water azeotropic mixture using Aspen Plus® and Aspen Split simulators. Calculation of vapor liquid equilibrium of Tetrahydrofuran–Water–Entrainer system was done using the NRTL model, which binary interaction parameters ...
