Background and Aim: Poor palatability, low bulk density, and low nutritive value restrict the utilization of the crop residues as animal feeds. Altering the physical characteristics of feed by blending the roughage and concentrates in the form of complete feed improves the nutrient use efficiency and reduces the feed wastage, feed cost, and labor cost. The study aims to determine suitable processing methods (mash, pellet, or block forms) for efficient utilization of sorghum stover-based complete rations vis-a-vis conventional feeding methods in sheep. Materials and Methods: The sorghum stover was incorporated in complete rations with roughage to concentrate ratio of 50:50 proportion in a growth trial of 120 days. The feed ingredients were chaffed, ground in a hammer mill, passed through expander-extruder, and compressed by feed block machine to prepare chop, mash, pellet, and block form of rations, respectively. Twenty-four male intact growing Nellore×Deccani cross lambs (3.5±0.5 months age, 14.50±0.41 kg (mean ± SD) at the start of the experiment) were divided into four experimental groups of six animals each in a complete randomized design. The experimental rations were randomly allotted to each group and evaluated for their intake, nutrient utilization, and growth performance. Results: The sheep fed on pellet-based ration consumed a higher (p<0.05) quantity of dry matter. The digestibility coefficients of organic matter, crude protein, and neutral detergent fiber were higher (p<0.05) in processed rations (mash, pellet, or block). Further, the nitrogen balance (g/d) was higher (p<0.05) in the mash, pellet, and block form of rations, compared to chopped ration. The processing method did not influence calcium or phosphorous balance parameters, except for their urinary losses, which showed an increasing trend (p=0.07). The ram lambs fed with pelleted ration showed higher (p<0.05) weight gain than mash, block, or chaff forms. The efficiency of feed utilization in gaining one kg body weight was higher (p<0.05) in lambs fed a pelleted diet. Feeding pelletized ration was more economical to gain one kg body weight. The bulk density was highest for block-based ration followed by pellet, mash, and conventional rations, and the carrying capacity of truck was highest with the least transport cost in block-form of rations. Conclusion: Physical processing (mash, pellet, and block) of sorghum stover-based complete rations increased the nutrient utilization and growth performance of sheep compared to conventional chopped form. Pelleting the mash with expander-extruder procedure was found to be more profitable. Nevertheless, the cost economics revealed blocks as more preferable forms for transporting the complete rations to larger distances.

Stage 1

This study was conducted to determine the effects of low-protein diet prepared with different levels of defatted rice bran (DFRB) and weight stages on growth performance and nutrient digestibility of growing–finishing pigs. The animal experiment included three stages. A total of 240 growing pigs with an initial body weight of 28.06 ± 8.56 kg for stage 1 were allocated to five diets including one control group and four DFRB diets supplemented with 2.5%, 5%, 7.5% and 10% DFRB, respectively. The 192 crossbred pigs with initial body weights of 55.03 ± 7.31 kg and 74.55 ± 9.10 kg were selected for stage 2 and stage 3, respectively. Pigs were allocated to four diets including one control group and three DFRB diets supplemented with 10%, 15% and 20% DFRB, respectively. The results showed that with the increase in DFEB intake, the gain: feed was linearly increased (p < 0.05), and the average daily feed intake tended to linearly decrease (p = 0.06) in stage 1. Except for the apparent total tract digestibility (ATTD) of acid detergent fiber (ADF) in stage 3, levels of DFRB had significant effects on the ATTD of gross energy (GE), dry matter (DM), ash, neutral detergent fiber (NDF) and ADF in three weight stages. In stage 1, with the increase in levels of DFRB, the ATTD of NDF and hemicellulose were firstly increased and then decreased (p < 0.01). In stage 2, with the increasing levels of DFRB, the ATTD of DM, ash and cellulose were firstly increased and then decreased (p < 0.01). In stage 3, the ATTD of GE, DM, ash, NDF and hemicellulose decreased linearly with the increase in levels of DFRB (p < 0.01). Collectively, DFRB could be used as a replacement for corns and soybean meal, and weight stage is important to consider when adjusting the additive proportion.

Abstract The objective of this study was to evaluate the effects of the source of silage, cereal grain, and their interaction on growth performance, digestibility, and carcass characteristics of finishing beef cattle. Using a completely randomized design within an 89-d finishing study, 288 steers were randomly assigned to 1 of 24 pens (12 steers/pen) with average steer body weight (BW) within a pen of 464 kg ± 1.7 kg (mean ± SD). Diets were arranged in a 2 × 3 factorial with corn silage (CS) or barley silage (BS) included at 8% (dry matter [DM] basis). Within each silage source, diets contained dry-rolled barley grain (BG; 86% of DM), dry-rolled corn grain (CG; 85% of DM), or an equal blend of BG and CG (BCG; 85% of DM). Total tract digestibility of nutrients was estimated from fecal samples using near-infrared spectroscopy. Data were analyzed with pen as the experimental unit using the Mixed Model of SAS with the fixed effects of silage, grain, and the two-way interaction. Carcass and fecal kernel data were analyzed using GLIMMIX utilizing the same model. There were no interactions detected between silage and grain source. Feeding CG increased (P &lt; 0.01) DM intake by 0.8 and 0.6 kg/d relative to BG and BCG, respectively. Gain-to-feed ratio was greater (P = 0.04) for BG (0.172 kg/kg) than CG (0.162 kg/kg) but did not differ from BCG (0.165 kg/kg). Furthermore, average daily gain (2.07 kg/d) and final body weight did not differ among treatments (P ≥ 0.25). Hot carcass weight (HCW) was 6.2 kg greater (372.2 vs. 366.0 kg; P &lt; 0.01) and dressing percentage was 0.57 percentage units greater (59.53 vs. 58.96 %; P = 0.04) for steers fed CS than BS, respectively. There was no effect of dietary treatment on the severity of liver abscesses (P ≥ 0.20) with 72.0% of carcasses having clear livers, 24.4% with minor liver abscesses, and 3.6% with severe liver abscesses. Digestibility of DM, organic matter, crude protein, neutral detergent fiber, and starch were greater for BG (P &lt; 0.01) than CG or BCG. As expected, grain source affected the appearance of grain kernels in the feces (P ≤ 0.04). Feeding CS silage increased the appearance of fractured corn kernels (P = 0.04), while feeding BS increased fiber appearance in the feces (P = 0.02). Current results indicate that when dry rolled, feeding BG resulted in improved performance and digestibility compared with CG and BCG. Even at low inclusion levels (8% of DM), CS resulted in improved carcass characteristics relative to BS.

Abstract Sufficient supply of dietary phosphorus (P) is critical for maximizing muscle and bone growth of pigs. The objective was to compare standardized total tract digestible (STTD) P requirements of growing pigs determined in the experiments and those estimated using modeling approach. Fifty-two experiments in the literature that empirically determined P requirements of pigs were employed. The basis for the determination of P requirements were growth performance (average daily gain or gain to feed ratio; n = 34) and bone development (n = 23). Based on the STTD P in the feed ingredients provided in NRC (2012) and ingredient composition used in the experiments, P requirements presented as total P, available P, and true total tract digestible P were converted to STTD P requirements. To obtain STTD P requirements (g/d) suggested by NRC (2012) for grow-finishing pigs (body weight &gt; 20 kg), mean body weight and sex indicated in the experiments were input into the NRC model. The statistical model for comparing the empirical data and the NRC requirements included the basis for determining P requirements in the experiments as a fixed variable and body weight as a random variable. To quantify the deviations between NRC STTD P requirement estimates and empirically determined STTD P requirements, mean percentage difference was calculated. The STTD P requirements empirically determined based on growth performance were greater than the NRC STTD P requirement estimates (5.89 vs. 4.61 g/d, SEM = 0.27; P &lt; 0.001). Moreover, the bone development-based STTD P requirements were greater than the NRC STTD P requirement estimates (6.63 vs. 4.46 g/d, SEM = 0.42; P &lt; 0.001). In conclusion, the standardized total tract digestible P requirements suggested by the NRC are less than the experimentally determined requirements.

This study assessed the effects of microalga Phaeodactylum tricornutum supplement on the gustation, stomach histology, growth performance and nutrient utilization of Clarias gariepinus juveniles. One hundred and fifty (150) C. gariepinus juveniles of mean weight 20.05±0.05g were distributed into 15 plastic tanks (40×30×35) cm3. Five graded levels (0.00 (control), 0.50, 1.00, 1.50, and 2.00g/100g of P. tricornutum supplements were included in the diets of C. gariepinus denoted as Control, PT1, PT2, PT4 and PT5, respectively. Fish were fed for 56 days at 5% body weight. Results at the end of the experiments showed that the highest body weight was recorded in fish fed 1.5g/100g P. tricornutum diets. The best feed conversion ratio, specific growth rate, protein efficiency ratio and percentage survival was found in PT3. There was significant difference (p<0.05) in the feed intake of fish with PT4 having the highest feed intake. The stomach histology revealed increase in the gustation cells in the stomach of experimental fish with increasing levels of P. tricornutum supplementation. This study showed that the inclusion of P. tricornutum supplement at 1.5g/100g level in the diet of C. gariepinus juveniles improved the gustation, growth performance and nutrient utilization of C. gariepinus.

Abstract The objective of this study was to evaluate the effect of long-term feeding of graded levels of DON on performance, nutrient utilization, and organ health of grower-finishing pigs. A total of 240 mixed-sex grower-finisher pigs (35.9 ± 1.1 kg initial body weight) were randomly assigned to 1 of 4 dietary treatments (6 pigs/pen; 10 pens/treatment) for 77 d. Diets consisted of a control diet without DON (CONT) and diets containing 1, 3, or 5 ppm DON (DON1, DON3, or DON5). Nitrogen-balance was determined in 1 pig/pen during week 6 and 12 of the study. Growth performance measures were taken weekly for average daily feed intake (ADFI), average daily gain (ADG), and gain:feed (GF) until d 77. Blood samples were collected on d 0, 14, 42, 56, and 84 from 1 pig/pen for analysis of indicators of liver and kidney function. On d 7, ADG and ADFI for pigs fed DON3 and DON5 diets were lower (P &lt; 0.05) compared to DON1- and CONT-fed pigs. Overall ADG and ADFI (d 0-77) were lower in DON3- and DON5-fed pigs compared to CONT and DON1 pigs (P &lt; 0.05), with no difference in GF (P &gt; 0.05). Final body weight was reduced in DON3- and DON5-fed pigs (P &lt; 0.05) compared to CONT and DON1, which were not different (P &gt; 0.05). No significant (P &gt; 0.05) treatment effects were observed on carcass characteristics. In the grower-phase, protein deposition (PD) was reduced in DON3 and DON5 pigs compared to CONT and DON1 pigs (P &lt; 0.05). In the finisher phase, PD was not affected by dietary treatment (P &gt; 0.05). There was no effect of dietary treatment on the majority of selected serum chemistry (P &gt; 0.05). In summary, pigs exposed to diets containing &gt; 1 ppm DON had reduced growth performance with little or no effect on nitrogen utilization, organ health, or carcass characteristics, suggesting that the negative effects of DON may be largely due to depressed feed intake.

Present study was undertaken to evaluate the effect of zinc supplementation on growth performance and nutrient utilization in kids. Twenty four goat kids (4-6 month age) were randomly divided into 4 groups (T1, T2, T3 and T4) having 6 kids each. Kids in the group T1 were fed basal diet which contained 29.02 mg Zn/kg DM from ingredients of ration without any additional Zn supplementation. Kids in the T2, T3 and T4 groups were fed the same basal diet with additive 20, 50 and 100 ppm Zn (as ZnSO4) in their diets, respectively. The study was conducted for 90 days. Digestion trial of 7 days was conducted towards the end of experiment to assess the digestibility of the nutrients. Results indicated significantly higher average body weight gain, crude protein (CP) digestibility and better feed efficiency in kids fed diet supplemented with 50.0 mg Zn/kg DM. From the results it was concluded that the Zn supplementation @ 50.0 mg/kg DM in basal diet significantly improved body weight (BW) gain, CP digestibility and feed efficiency ratio (FER) of kids.

The study was planned to evaluate the effect of exogenous fibrolytic enzymes (EFE) supplementation for 56 days @ 240 mg/kg total mixed ration (TMR) on digestibility of dry matter and nutrients in dairy cows. Six dry non-pregnant cows were assigned in each treatment with and without EFE. The digestibility trial of seven days was conducted after 49 days of feeding. Dry matter and nutrients intake of cows was not influenced by EFE. The supplementation of EFE had improved digestibility of dry matter, organic matter, crude fiber, neutral detergent fiber, cellulose (p less than 0.01), as well as digestibility of nitrogen-free extract and acid detergent fiber, was also higher (pless than 0.05). The body weight gain of cows was higher on the supplementation of EFE in TMR. The study concluded that feeding exogenous fibrolytic enzymes (240 mg/kg) supplemented TMR improved digestibility of dry matter and nutrients, which was reflected as higher body weight gain in dry non-pregnant Gir and crossbred dairy cows.

Soy protein concentrate improves nutrient utilization and growth performance compared to soybean meal, and diets with a low crude protein (CP) level decreases diarrhoea. The objectives were to (1) test a low CP diet based on different soy products, and (2) to test a very-low CP diet (15.1%) with amino acids (AA) on diarrhoea and productivity. A total of 5,635 weaned pigs (~28 days), were assigned to five dietary treatments; PC (positive control): Standard CP levels (192, 189, 191 g/kg CP) with 2500 ppm ZnO; NC (negative control): Same as PC without ZnO; SP (Soy protein concentrate): Low CP levels (176, 174, 191 g/kg CP); SB (Soybean meal): Low CP levels (177, 176, 191 g/kg CP); and XLA (X-low CP + AA): Very low CP levels (154, 151, 191 g/kg CP) with AA. The PC and XLA diets reduced diarrhoea by 41 and 61%, respectively, compared to the NC group, while no difference between SB and SP were observed. The XLA diet reduced feed intake and daily gain compared with PC and NC, where SP, SB, and XLA had a poorer feed conversion compared with PC. Conclusively, the SP and SB low-protein diets did not reduce diarrhoea or growth performance, whereas the XLA diet decreased both diarrhoea and performance.

Abstract Benzoic acid (BA) and essential oils (EO) can minimize growth performance losses due to the removal of antibiotics and change the intestinal health of weaned piglets. The objective of this study was to evaluate the effects of BA and EO on inflammatory response, diarrhea incidence, and growth performance of the nursery phase. One hundred and twenty barrows were weaned at 23 days (6.40 ± 0.53 kg) and assigned into 3 treatments (10 replicates) in randomized block design: basal diet without additives (NC), basal diet with 200 ppm of colistin sulphate (PC), and association of 0,3% benzoic acid and essential oil (BA+EO). The feed intake and body weight were recorded at 0 and 42 days. The feces were assessed daily (per animal) and graded as normal feces (no diarrhea) or liquid or pasty stools (presence of diarrhea). On days 1, 3, and 9, blood samples were collected (5 replicates) for white blood cells (WBC) counts. Growth performance was analyzed by MIXED procedure (SAS, 2009) and the Tukey test was used to compare the means (P &lt; 0.050). The WBC counts were analyzed by repeated-measures analysis of variance, by MIXED procedure. Diarrhea incidence was analyzed by GENMOD procedure (SAS, 2009). The BA+EO treatment showed a similar body weight (P = 0.014) and average daily gain (P = 0.012) than the PC group and lower feed conversion ratio (P = 0.037) compared to the NC group. The pigs of the BA+EO treatment had the lowest diarrhea incidence during the total period (P &lt; 0.001). The supplementation with BA+EO or antibiotics reduced the counts of total WBC (P = 0.008) and neutrophils (P = 0.003). In conclusion, supplementation with BA+EO reduces the inflammatory response and the incidence of diarrhea in the nursery phase, that may be related to the improvement in the FCR.
