1. 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

2. Blood parameters of Angus and Nellore young bulls fed diets with or without forage.
ABSTRACT We evaluated blood parameters of Angus and Nellore bulls fed diets with and without forage. Forty animals with initial body weight (BW) of 380±16.2 kg were housed in individual stalls. Eight bulls of each breed were fed a whole shelled corn (WSC) diet [850 g kg−1 of WCS and 150 g kg−1 of a pellet based on soybean meal, dry mater (DM) basis] or

3. Feed restriction of F1 Holstein × Zebu cows in the final third of lactation modifies intake, nutrient digestibility, feeding behavior, and performance
ABSTRACT The objective of this study was to evaluate the effect of quantitative feed restriction level on nutrient intake and digestibility, nitrogen balance, efficiency and feeding behavior, and productive performance of F1 Holstein × Zebu cows in late lactation. Sixty F1 Holstein × Zebu cows were used at the stage of late lactation (183.0±17.5 days of l

4. Meat properties and fatty acid profile of swine fed cashew bagasse bran in qualitative food restriction program
ABSTRACT The purpose of this study was to evaluate the effects of qualitative dietary restriction diet on carcass characteristics, meat quality, fatty acid profile, and performance of finishing pigs fed diets containing cashew bagasse bran. Forty pigs (20 females and 20 males) with initial weight of 60.00±5.24 kg of body weight (BW) were used. The diets wer

5. Effects of feed restriction and forage:concentrate ratio on digestibility, methane emission, and energy utilization by goats
ABSTRACT This study was carried out to to evaluate how feed restriction and different forage:concentrate ratios affect digestibility, methane emission (using the SF6 technique), and energy utilization of Anglo-Nubian goats. Fifteen (15) dry and non-pregnant Anglo Nubian goats, averaging 30±2.9 kg body weight, were used. The experiment was divided into two t

6. Effects of the Addition of Pure Glycerin Supplementation in the Drinking Water on the Performance of Broilers Submitted to Heat Stress and Feed Restriction
ABSTRACT The experiment was conducted to study the effect of pure glycerin supplementation (GLYC) in the drinking water of broilers subjected to heat stress and feed restriction. Water with 0, 1, or 2% glycerin was provided ad libitum to broilers in six hours of feed restriction. The birds were housed in two environments: thermoneutral (TN) - 25 ° C, and cy

7. Effect of different feed restriction regimens on lamb performance and carcass traits
Fifty Najdi ram lambs weighing an average of 38.1±0.5 kg were utilized in this study to determine the effects of feed restriction level with or without subsequent realimentation on lamb performance and carcass composition. Lambs were allotted randomly and equally into five groups. The groups were fed a control diet ad libitum; two groups fed 0.90 and 0.80 o

8. Effect of restricted feeding and realimentation on feed performance and carcass characteristics of growing lambs
Forty Najdi ram lambs weighing 26.6±0.3 kg were utilized in this experiment to determine the effects of feed restriction followed by realimentation and body weight at the onset of feed restriction (30 and 36 kg body weights) on performance and carcass characteristics; feeding and restriction levels were ad libitum, 0.75 and 0.60 of the ad libitum intake. Al

9. Estimation of endogenous contribution and urinary excretion of purine derivatives from the total digestible nutrient intake in Nellore heifers
The objectives of this experiment were to estimate the endogenous excretion of purine derivatives (PD), the intake and digestibility of nutrients, the urinary excretion of PD from the intake of total digestible nutrients (TDN) and digestible organic matter (DOM) in Nellore heifers. Eight heifers, 267±17 kg body weight (BW), were assigned to two 4 × 4 latin

10. Exigências e eficiência energética e protéica de ovinos Dorper x Santa Inês alimentados com dietas contendo volumosos de valor nutricional distinto. / Requirements and efficiency of energy and protein use for Dorper × Santa Inês sheep fed diets containing roughages with different nutritive value
The objective of this study was to evaluate the effect of using roughages with different nutritive value on requirements and efficiency of energy and protein use of growing ½ Dorper × ½ Santa Inês sheep. For this purpose, eighty four non-castrated male lambs were weaned at 56 days of age (initial BW = 18.0 ± 3.3 kg) and penned in individual stalls, bein

11. Estimativa da excreção urinária de derivados de purinas a partir do consumo de NDT e determinação da contribuição endógena em bovinos de corte / Estimation of urinary excretion of purines derivatives from TDN intake and determination of the endogenous contribution in beef cattle
Two experiments were conducted with eight Nelore heifers (BW 267 17 kg ) to assess the excretion of purine derivatives (PD) from intake of TND, the intake and digestibilities of nutrients and the endogenous fraction of PD and nitrogen losses using the technique of fasting. In Exp.I the animal were fed a diet based on corn silage and concentrate in the propor

12. Performance and hormonal profile in broiler chickens fed with different energy levels during post restriction period.
The aim of this work was to investigate the influence of diet energy level on performance and hormonal profiles of broilers during post restriction period. It was a split-plot experiment, and the main treatments were in a 2x2 factorial scheme. Birds were fed restricted to 30% of the ad libitum intake, from 7 to 14 days of age. After the restriction period, b
