Dietary soluble fibre limits the incidence of epizootic rabbit enteropathy (ERE) and improves the energy and nitrogen balance in low-insoluble fibre diets, while high-insoluble fibre diets seem to favour ERE. This study assessed whether the positive effects of soluble fibre are influenced by the level of insoluble fibre. Four diets (2 × 2 factorial arrangement) were used with two levels of insoluble fibre (314 vs. 393 g/kg DM) and soluble fibre (87 vs. 128 g/kg DM), resulting in four diets with increasing total dietary fibre levels. Growth performance and chemical composition (body and carcass) (28–62 days of age), faecal digestibility (54–57 days of age), and jejunal morphometry functionality (39 days of age) were determined. Mortality was low (<1%) and treatments did not influence it. Insoluble and soluble fibre tended to reduce the growth rate (p ≤ 0.109), body protein, and fat accretion (p = 0.049 to 0.120), but only insoluble fibre impaired feed efficiency (p < 0.001). The efficiency of digestible energy used for growth was impaired with the increase of total dietary fibre (p = 0.027), while that of nitrogen remained majorly unaffected. In conclusion, in healthy rabbits, the increase of either insoluble or soluble fibre had no benefit.

Reconstituted Milk

The present experiment was carried out to assess the effects of reconstituted milk (RM), acidified reconstituted milk (ARM), and acidified fresh milk (AFM) on growth performance, diarrhea rate, and hematological parameters of preweaning dairy calves. For this purpose, a total of 27 Holstein female calves (one month of age) with initial body weight of (67.46 ± 4.08) kg were divided into three groups in such a way that each group contained nine calves. Calves were housed individually, and starter was offered ad libitum to each calf. The dietary treatments were RM, ARM, and AFM. The highest milk intake was observed in calves receiving AFM as compared to other treatments (p < 0.01). Calves fed AFM had more feed intake than those fed ARM and RM (p < 0.01). Feed efficiency was significantly lower for calves offered ARM than those offered RM and AFM (p < 0.01). A lower withers height growth was found for calves fed RM than those fed ARM and AFM (p <0.05). Diarrhea rate and white blood cell (WBC) and lymphocytes (LYM) counts were greater for calves fed RM than those fed ARM and AFM (p < 0.05). These findings suggested that ARM and AFM had positive effects on growth performance and health status of the preweaning dairy calves.

AbstractDespite growing evidence suggesting a potential health benefit of high fibre intake for the prevention of chronic inflammatory diseases, studies regarding the role of total dietary fibre intake, types and sources of fibre on asthma are lacking. The present study aimed to investigate the cross-sectional association of dietary fibre intakes and source of fibre with the asthma symptom score and asthma control. A total of 35 380 participants from the NutriNet-Santé cohort were included. Asthma was defined by the asthma symptom score and asthma control by the asthma control test. Fibre intake (g/d) was categorised according to sex-specific quintiles. Multi-adjusted negative binomial regressions were used to evaluate the association between dietary fibre with the asthma symptom score and logistic regressions with asthma control. Participants were aged on average 54 years. After adjustment for confounders, higher intake of total, soluble, insoluble fibres from cereals, fruit and seeds were significantly negatively associated with the asthma symptom score both among women and men; OR for the highest quintile of total dietary fibre compared with the lowest quintile were 0·73 (95 % CI 0·67, 0·79) in women and 0·63 (95 % CI 0·55, 0·73) in men. We also found inverse significant associations between total, soluble and insoluble fibre with uncontrolled asthma; OR for participants in the highest quintile of total dietary fibre was 0·72 (95 % CI 0·55, 0·95) in women and 0·45 (95 % CI 0·26, 0·79) in men. Our results suggested that higher intake of dietary fibre, mostly insoluble fibre and fibre from cereals, was associated with fewer asthma symptoms and greater asthma control.

Duplicate groups of seawater-adapted 70-g all-female chinook salmon (Oncorhynchus tshawytscha) were held in flowing seawater (24–29‰; 8–12 °C) corresponding to swimming speeds (SS) of 0.5, 1.0, or 1.5 body lengths (bl)/s for 212 d. Fish were fed either a maximum satiating ration of 75% of maximum ration at each SS. Fish grew four- to fivefold during the study, but neither mean body weight, fork length, specific growth rate, condition factor, nor muscle morphometry was influenced by average SS. However, the SS of individually marked fish were negatively correlated with specific growth rate. At both rations, higher SS increased the internal tissue-carcass ratio, hepatosomatic index, and total body protein. More food was ingested at higher SS resulting in reduced feed efficiency. SS did not alter the plasma L-thyroxine (T4) concentration, but increased the plasma 3,5,3′-triiodo-L-thyronine (T3) concentration and T3/T4 ratio. In part, this may reflect the greater food intake at higher SS. The reduced ration depressed all aspects of growth and at 212 d tended to depress both plasma T4 and T3, but did not alter feed efficiency. We conclude that exercise over the range of 0.5–1.5 bl/s does not enhance growth, but reduces feed efficiency in seawater-adapted chinook salmon.

The objective of this study was to determine the concentrations of total dietary fibre (TDF), insoluble dietary fibre (IDF) and soluble dietary fibre (SDF) in the samples of whole or dehulled seeds of Lupinus albus (L.) and Glycine max (L.), and to assess the effect of dehulling on the concentrations obtained. The results showed a higher content of TDF and IDF and a lower content of SDF in lupine seeds compared to soybeans. Lupine seed dehulling resulted in a lower content of TDF (P < 0.05) and IDF (P < 0.05), and a higher content of SDF. Following soybean dehulling, the increase of SDF (P < 0.05) and decrease of IDF but no effect on TDF was reported. The proportion of IDF (90.4 vs. 96.0%) and SDF (9.6 vs. 4.0%) in TDF changed only slightly following lupine seed dehulling, whereas in soybeans, the proportion of IDF markedly decreased (91.8 vs. 73.0%), and SDF increased (8.2 vs. 27.0%). The effectiveness of dehulling with regard to soluble fibre was higher in soybeans compared to lupine seeds. In lupine, dehulling did not show any significant increase of nutritional value concerning the proportion of insoluble fibre in cotyledon. Due to the content of insoluble fibre in lupine seeds, their proportion in the ration of animals should be considered.

Different Levels

High ambient temperature reduces feed intake, live weight gain, and feed efficiency (Siegel, 1995), thus negatively influencing the performance of broilers. Heat stress has also been shown to suppress immune responses of broiler. Chromium is an essential nutrient required to promote the action of insulin in body tissues so that the body can use sugars, proteins and fats. Cr deficiency can disrupt carbohydrate and protein metabolism, reduce insulin sensitivity in peripheral tissues and impair growth rate (Vincent, 2000).Chromium is important in altering the immune response by immunostimulatory or immunosuppressive processes as shown by its effects on T and B lymphocytes, macrophages and cytokine production. Dietary chromium supplementation has been reported to have a positive effect on growth rate and feed efficiency of growing poultry under stress conditions (Sahin et al., 2002). Another reason for supplementing chromium is due to the fact that chromium is excreted excessively during stress (Anderson, 1994). Also the dietary requirement of livestock for chromium has not been defined yet (NRC, 1997). This study was to investigate the effects of different levels of Cr nicotinate on the growth performance and antibody titres against Newcastle and Influenza disease in broilers.

The study of probiotic application as an important rearing strategy was started more than 30 years ago and most of these studies were carried out to increase growth and survival of larvae. Effect of Bifidobacterium animalis PTTC-1631 and B. lactis PTTC-1736 as probiotic supplement has been studied on growth performance and hematological changes on rainbow trout, Oncorhynchus mykiss alevins with initial body weight of 0.583 ± 0.197 g. The commercial diet was supplemented with graded levels of probiotics (1×107, 2×107 and 3×107 CFU g-1 dry feed) to obtain 3 sets of experimental diets (T1, T2, andT3 respectively) and fed four times a day for 60 days. T1 alevin showed the best growth performance in terms of specific growth rate, weight gain, metabolic growth rate, feed conversion ratio and survival rate. The highest red and white blood cell concentrations were noticed in fish fed T2 and T3 diets, respectively, no significant difference was observed in hemoglobin content. T1 showed the significant elevation of serum biochemical parameters and reduction of cortisol level. The results of present study might suggest likely positive effects of probiotic supplements with concentration of 1×107 CFU g-1 dry feed on growth and hematology on rainbow trout alevins.

Abstract Ninety steers (259.9 ± 36.18 kg BW) were used in a 56-d experiment to assess the effects of flavoring additives on feeding behavior, feed efficiency, growth performance, and temperament of newly arrived feedlot cattle. Steers were homogenously distributed by BW into six pens (15 head/pen) and pen was randomly assigned to one of 3 treatments (2 pens/treatment): a standard feedlot receiving diet (CT); or the same diet with a flavoring additive comprised of either sweeteners (SW) or a mix of basic tastes (MX) at 1 g/kg (Lucta SA, Barcelona, Spain). Pens were equipped with a feed intake monitoring system (Growsafe Systems, Airdrie, Canada), while BW and chute exit flight speed were measured bi-weekly during the study. Data were analyzed using a mixed-effects model accounting for repeated measures. There were multiple treatment × time interactions (P &lt; 0.05), where DMI per meal was greater in SW than CT and MX on wk 3 and 5, respectively, and in MX than CT and SW on wk 3 and 7, respectively. The number of visits to the feed bunk per day was greater in MX than CT on wk 2, it was greater in SW than MX on wk 4, and it was greater in CT than in MX and SW on wk 4, and wk 7 and 8, respectively. The eating rate was greater in SW than MX on wk 4 and 5 and greater than CT and on wk 4. Although the cumulative responses for DMI, ADG and feed efficiency (FE; kg BW/kg DM) were not significant (P &gt; 0.1), FE was greater in SW and MX than CT from 27 to 41 d. Despite these positive effects on FE, there was no feeding pattern associated with the inclusion of flavoring additives in the diet of receiving feedlot cattle.

Abstract Four experiments were conducted using 1,100 to 1,188 pigs each (PIC 359 × 1,050) from ~27 to 127 kg BW to evaluate phase-feeding strategies based on Lys specifications and number of dietary phases for grow-finish pigs. Different phase-feeding strategies were used in each experiment with treatments consisting of a combination of 3 Lys specifications at 96%, 98%, or 100% of estimated requirement for growth rate and 4 phase-feeding strategies with 1, 2, 3, or 4 dietary phases. A single-phase-feeding strategy reduced (P &lt; 0.05) overall growth performance, live BW, and HCW whether Lys specifications were at 98% or 100% of estimated requirements compared with multi-phase-feeding strategies. Lysine specifications at 96% of estimated requirements in a 4-phase-feeding strategy reduced (P &lt; 0.05) overall growth performance compared with feeding strategies with Lys at 100% of estimated requirements, unless Lys specifications were increased to 100% of estimated requirements in the late finishing phase. Lysine specifications at 98% or 100% of estimated requirements in a 2-, 3- or 4-phase feeding strategy led to similar (P &lt; 0.05) overall growth rate, live BW, and HCW of grow-finish pigs. Pigs fed 1, 2, or 3-phase feeding strategies or feeding strategies with Lys below the requirements in early grow finish had improved growth performance driven by improved feed efficiency in the period following low Lys levels, indicating the occurrence of compensatory growth. For carcass characteristics, there was no evidence (P &gt; 0.10) for differences in carcass yield, back fat, loin depth, or lean percentage across feeding strategies in any of the experiments. In conclusion, phase-feeding strategies provide performance advantages over feeding a single dietary phase throughout the grow-finish period. Simplification of feeding strategies from 4 to 3 or 2 dietary phases with Lys specifications at 98% to 100% of estimated requirements for growth rate does not compromise overall growth performance and carcass characteristics of grow-finish pigs from 27 to 127 kg BW. Although, using feeding programs with fewer dietary phases and Lys set slightly below the requirements can compromise growth performance if initial BW and feed intake in the grow-finish period are lower than expected.

A total of 288 Landrace × Yorkshire boars, gilts and barrows selected for low backfat were used in two trials to determine the effect of an increased dietary ratio of true ileal digestible methionine to lysine on growth performance, carcass merit and nutrient utilization. The three experimental grower and finisher diets were: (1) barley-soybean meal diets with no supplemental amino acids as control containing true ileal digestible lysine at 0.45 and 0.36 g MJ–1 DE in grower and finisher diets, respectively, (2) the same as diet 1 with supplemental lysine to provide true ileal digestible lysine at 0.65 and 0.49 g MJ–1 DE, and supplemental threonine and methionine to give ratios of 0.7 and 0.3, respectively, to lysine on a true ileal digestible amino acid basis, and (3) the same as diet 2 with an increased true ileal digestible methionine to lysine ratio of 0.4. All diets were fed as pellets ad libitum in self-feeders, and with free access to drinking water. The ADG and FCE during the grower, finisher and overall periods were higher (P < 0.05) for diets 2 and 3 than for diet 1, but they were not different between diets 2 and 3 in boars, gilts and barrows. The lean growth rate and whole body protein accretion were also higher (P < 0.05) for diets 2 and 3 than for diet 1, but they were not different between diets 2 and 3 in boars, gilts and barrows. The apparent faecal digestibilities of dry matter and energy, as well as nitrogen retention and excretion, were similar (P > 0.05) for all the diets. The results indicated that boars and gilts in the present study may not have reached the maximum genetic potential for lean growth rate due to an inadequate feed and amino acid intake. A lack of improvement in pig performance with a higher dietary ratio of true ileal digestible methionine to lysine (0.40 vs. 0.3) indicated that the current NRC recommendations may be adequate. Key words: Pigs, amino acids, lysine, methionine, growth performance, nutrient metabolism.
