Effect of wild ginseng on the laying performance, egg quality, cytokine expression, ginsenoside concentration, and microflora quantity of laying hens.

The experiment was carried out to study the effect of Korean wild ginseng adventitious root supplementation on the laying performance, egg quality, cytokine expression, ginsenoside concentration, and microflora quantity of Institut de selection Animale (ISA) brown laying hens at 24 weeks old. A total of 90 laying hens were subjected to a completely randomized design at three treatments, five repetitions and six laying hens per replicate. The experiments were divided by diets into the basic feed (CON), basic feed + 0.

Prediction of calcium and phosphorus requirements for pigs in different bodyweight ranges using a meta-analysis.

Several studies have focused on Ca and P requirements for pigs. These requirements are estimated from their retention and bone formation. However, modern pig breeds have different responses to dietary Ca and P than traditional breeds, and their requirements are expected to change on an annual basis.

Behavioral and stress responses to feeding time in pregnant sows under limit-fed regime.

We investigated the effect of feeding time on behavior and stress responses in pregnant sows under isocaloric conditions. Twenty-four sows were balanced for parity and randomly assigned to 1 of 3 feeding times. Corn-soybean meal-based diet was fed once at: 0730 (Control, T1), 1130 (T2), and 1530 hours (T3).

Arginine addition in a diet for weaning pigs can improve the growth performance under heat stress.

The effects of arginine (Arg) and methionine (Met) supplementation on nutrient use in pigs were determined under hot season conditions. A total of five experimental diets including basal diet (CON) were supplemented with two types of amino acids (Arg and Met) and two different amounts of amino acids (0.2% and 0.

Behavioral and cortisol responses to feeding frequency in pregnant sows under isocaloric intake.

The study focused on behavioral and cortisol responses to feeding frequency in pregnant sows under isocaloric intake. Twenty-four sows [(Landrace × Yorkshire); BW 216.70 ± 3.

The Ratio of Dietary n-3 Polyunsaturated Fatty Acids Influences the Fat Composition and Lipogenic Enzyme Activity in Adipose Tissue of Growing Pigs.

Currently, there is a growing interest among consumers in selecting healthier meat with a greater proportion of essential fatty acids (FA). This experiment was conducted to evaluate the role of different ratios of dietary n-6:n-3 on growth performance, FA profile of (LD), relative gene expression of cytokines, meat quality, and blood parameters in finishing pigs. A total of 108 finishing pigs was randomly allotted to three treatments including a control (basal diet) and low ratios (4:1 and 2:1) of n-6:n-3.

Age and weight at first mating affects plasma leptin concentration but no effects on reproductive performance of gilts.

The objective of this study was to verify the best mating age of gilts at the first parity. Gilts (n = 86) were divided into nine groups in a factorial arrangement with three Ages (AG1, ≤ 220 d; AG2, 220 to 240 d; AG3, 240 ≤ d), and three weights (WT1 ≤ 140 kg; WT2, 140 to 149 kg; WT3, 150 ≤ kg). A higher body weight gain in AG2 sows during gestation.

Effect of feeding frequency and sow parity based on isocaloric intake during gestation on sow performance.

The aim of this study was to investigate the effect of feeding frequency and sow parity based on same rate of maintenance energy intake during gestation on sow performance. One hundred and seventy-seven sows [Topigs Norsvin 70, Landrace × Large White, Topigs Norsvin USA, Burnsville, MN; parity 3.80 ± 0.

Effects of as fucoidan-rich algae on growth performance, nutrient digestibility, intestinal morphology and caecal microflora in weanling pigs.

Objective: In the present study, role of increasing levels of (seaweed) supplementation in diets was investigated on growth performance, coefficient of total tract apparent digestibility (CTTAD) of nutrients, serum immunoglobulins, cecal microflora and intestinal morphology of weanling pigs.

Methods: A total of 200 weaned pigs (Landrace×Yorkshire×Duroc; initial body weight 7.08±0.

Erratum to: Comparative ileal amino acid digestibility and growth performance in growing pigs fed different level of canola meal.

Comparative ileal amino acid digestibility and growth performance in growing pigs fed different level of canola meal.

The digestibility of different vegetable protein sources were investigated and the effects of supplementing canola meal (CM) as partial inclusions were studied in growing pigs, to determine the performance parameters and its economic importance. In Exp. 1, four pigs (average initial BW = 15.
