Effect of feeding wheat- or barley-based diets with low or and high nutrient density on nutrient digestibility and growth performance in weaned pigs

X. Zhou, E. Beltranena, R.T. Zijlstra

Animal Feed Science and Technology > 2016 > 218 > C > 93-99

Barley grain is commonly fed to growing-finishing pigs as the major cereal feed energy source in western Canada. However, its nutritional value for weaned pigs is poorly characterized. Formulating low nutrient dense diets may reduce feed cost. Weaned pigs may be able to maintain growth performance by adjusting feed intake to meet nutrient requirement. Four diets based on either 644g wheat/kg or 676g...

Effect of supplementing barley straw with lucerne silage or cottonseed meal on diet digestibility and growth rate of steers

Animal Feed Science and Technology > 2016 > 218 > C > 84-92

Two experiments, separately examining digestibility (Experiment 1) and growth (Experiment 2), were conducted concurrently to investigate the effects of supplementation with either increasing amounts of lucerne silage (Medicago sativa) or a single amount of cottonseed meal (CSM—Gossypium hirsutum) on the utilization of barley straw (Hordeum vulgare) by yearling Hereford steers (284–342kg liveweight...

Animal Feed Science and Technology > 2016 > 218 > C > 100-109

This study explored the effects of one ionophore compound (monensin) and four pure extracts (limonene, allyl sulfide, cinnamaldehyde, and eugenol) on in vitro rumen fermentation and methane (CH₄) production of a commercial diet for dairy cows. Four consecutive incubations at 24h were conducted using an automated gas production (GP) system, where gas was vented at fixed pressure. Bottles (317ml) were...

Water-soluble fractions obtained by enzymatic treatment of wheat grains promote short chain fatty acids production by broiler cecal microbiota

Nadia Yacoubi, Filip Van Immerseel, Richard Ducatelle, Lamya Rhayat, more

Animal Feed Science and Technology > 2016 > 218 > C > 110-119

The use of exogenous cell wall degrading enzymes to improve the nutritional values of cereal grains has increased during the last decades. In this study, products from enzymatic hydrolysis of wheat grain were isolated and their ability to induce short-chain fatty acids was investigated using in vitro fermentation with cecal microbiota. Water-soluble fractions were obtained following incubation without...

Effects of ruminal and post-ruminal protein supplementation in cattle fed tropical forages on insoluble fiber degradation, activity of fibrolytic enzymes, and the ruminal microbial community profile

Animal Feed Science and Technology > 2016 > 218 > C > 1-16

The aim of this study was to evaluate the effects of ruminal and abomasum protein supplementation in cattle consuming tropical forages on nutritional characteristics, fibrolytic enzymatic activity, in vitro degradation of insoluble fiber, and the ruminal microbial community profile. Two experiments were sequentially conducted and differed only in the forage quality that was offered: medium-quality...

Effects of dietary mannan oligosaccharide supplementation on performance and immune response of sows and their offspring

X.D. Duan, D.W. Chen, P. Zheng, G. Tian, more

Animal Feed Science and Technology > 2016 > 218 > C > 17-25

The present study investigated the effects of mannan oligosaccharide (MOS) supplementation of the diets of sows and/or their offspring on maternal and offspring performance and immune status. Sixty multiparous sows were fed either the control diet (sCON, n=30) or the control diet containing 400mg/kg MOS (sMOS, n=30) from d 86 of gestation until weaning. On d 7 of age, offspring were assigned within...

Diet nutrient digestibility and growth performance of weaned pigs fed wheat dried distillers grains with solubles (DDGS)

L.F. Wang, E. Beltranena, R.T. Zijlstra

Animal Feed Science and Technology > 2016 > 218 > C > 26-32

Biofuel co-products such as wheat distillers dried grains and solubles (DDGS) are used increasingly in swine feed to reduce feed cost. Wheat DDGS is rich in protein and phosphorus, thus may replace soybean meal (SBM) in swine diets. To explore, the effects of increasing inclusion of wheat DDGS by substituting SBM on diet nutrient digestibility and growth performance of young pigs were evaluated. In...

Digestibility and energy value of pea (Pisum sativum L.), faba bean (Vicia faba L.) and blue lupin (narrow-leaf) (Lupinus angustifolius) seeds in broilers

E. Koivunen, K. Partanen, S. Perttilä, S. Palander, more

Animal Feed Science and Technology > 2016 > 218 > C > 120-127

An experiment was carried out to determine the apparent metabolizable energy (AME) and coefficient of apparent ileal digestibility (CAID) of nutrients of two pea cultivars (Pisum sativum L. ʻSohviʼ and ʻKaritaʼ), two fava bean cultivars (Vicia Faba L. ʻKontuʼ and ʻUkkoʼ) and one blue (narrowleaf) lupin cultivar (Lupinus angustifolius ʻPershatsvetʼ) in 144 5-week-old broilers. The methods used were...

Nutritional value of feed ingredients of plant origin fed to pigs

H.H. Stein, L.V. Lagos, G.A. Casas

Animal Feed Science and Technology > 2016 > 218 > C > 33-69

Since the 1950’ties, most diets fed to commercially raised pigs have been formulated based on plant feed ingredients and without using animal feed sources. Cereal grains have historically been the main stable in pig diets, but because pigs require nutrients rather than specific feed ingredients, it is possible to provide a well-balanced diet that includes all necessary nutrients using a large number...

Comparative performance of broiler chickens offered ten equivalent diets based on three grain sorghum varieties as determined by response surface mixture design

S.Y. Liu, H.H. Truong, A. Khoddami, A.F. Moss, more

Animal Feed Science and Technology > 2016 > 218 > C > 70-83

Ten nutritionally-equivalent diets containing 620g/kg grain sorghum, based on seven blends and three varieties (Block I, HP, Liberty), were offered to a total of 360 male Ross 308 chicks from 7 to 28days post-hatch. The effects of dietary treatments on growth performance, nutrient utilisation, starch and protein (Nitrogen) digestibility coefficients, disappearance rates and starch:protein disappearance...
