In this study, the feeding behavior of Nellore heifers receiving supplements containing mineral salt, conventional urea and slow release urea during the grazing stage at Brachiaria brizantha-based pastures during the dry period of the year was evaluated. Fifty-six heifers with approximately 284.72 ± 27.48 kg of body weight were used, distributed in a completely randomized design with four different treatment types: mineral salt; Urea - supplementation with 8.18% conventional urea; Mixed urea - supplementation with 4.09% conventional urea and 4.39% slow release urea and slow urea - supplementation with 8.78% slow release urea. Animals supplemented with mineral salt had longer grazing times compared to those supplemented with mixed urea, slow urea and regular urea. The dry matter intake, neutral detergent fiber and total digestible nutrients presented a similar effect, with higher values for heifers consuming supplements containing regular urea and slow urea compared to those of mixed urea. However, when the efficiency of hourly intake was evaluated, the animals that received urea supplement were more efficient in relation to the other treatments. The number of grazing periods for heifers receiving slow urea supplementation was higher compared to heifers receiving salt and mixed urea. The duration of grazing and rumination periods was longer for heifers receiving salt supplementation and mixed urea than those receiving regular urea and slow urea. It is recommended to use supplements at the level of 0.3% of body weight for heifers receiving conventional urea.

This study aimed to assess the fermentation profile, losses and chemical composition of the silages of five sorghum cultivars. A completely randomized design with five replicates was used. The experimental treatments were represented by five sorghum cultivars (Sorghum bicolor (L). Moench): 'BRS Ponta Negra' , 'BRS 610', 'BRS 655', 'BRS 800' and 'BRS 810'. There was variation (P<0.05) for the pH in the cultivars studied, with highest result of pH by 'BRS 610'. The average percentages of lactic acid, acetic acid and propionic acid, differed (P<0.05) among the cultivars, ranging from 32.9 to 59.5, 19.8 to 39.8, and 0.0 to 1.3g kg-1, respectively. The dry matter recovery varied among cultivars (P<0.05), allowing the identification of BRS Ponta Negra, and 'BRS 810' silages, as those which recovered the lowest dry matter, with values of 757.1 and 776.1g kg-1, respectively. There were differences (P<0.05) for dry matter, crude protein, ether extract, neutral detergent fiber, non-fibrous carbohydrates and total carbohydrates contents among the cultivars. It was concluded that, despite the morphological and chemical differences among cultivars, the resulting silages had good fermentation profile.

ABSTRACT: The inner bark or less tender sheath generated from industrial manufacture of canned babassu palm (Attalea speciosa) heart is inadequate for human consumption, often being discarded inappropriately and giving rise to environmental pollution. Accordingly, the aim of this study was to assess the intake and digestibility in sheep fed on silage of the agro-industrial co-product of babassu palm (ICBP)enriched with different additives, or on sugarcane silage. Fifteen Santa Inês sheep were distributed in a completely randomized design, consisting of five treatments and three replicates. The treatments comprised babassu palm silage enriched with broken maize (BM), broken rice (BR), cassava scrapings (CS), coffee husk combined with maize kernel (CC), and sugarcane silage (SC), all supplemented with concentrate, at a voluminous:concentrate ratio of 65:35. Silages based on ICBP and SC had similar intake of dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), and non-fibrous carbohydrate (NFC). Increasing the additive fraction in ICBP silages favored the digestibility of DM, OM, CP, NFC, neutral detergent fiber (NDF), and total digestible nutrients (TDN). Our results indicated that silage based on additive-enriched ICBP can be used in the diet of ruminants, especially those based on broken maize and cassava scrapings that provide superior nutritional quality compared to the other silages assessed.

Abstract This study evaluated the effect of combinations of feed-grade urea and slow-release urea (SRU) on fermentation and microbial protein synthesis within two artificial rumens (Rusitec) fed a finishing concentrate diet. The experiment was a completely randomized, dose–response design with SRU substituted at levels of 0% (control), 0.5%, 1%, or 1.75% of dry matter (DM) in place of feed-grade urea, with four replicate fermenters per dosage. The diet consisted of 90% concentrate and 10% forage (DM basis). The experiment was conducted over 15 d, with 8 d of adaptation and 7 d of sampling. Dry matter and organic matter disappearances were determined after 48 h of incubation from day 9 to 12, and daily ammonia (NH3) and volatile fatty acid (VFA) production were measured from day 9 to 12. Microbial protein synthesis was determined on days 13–15. Increasing the level of SRU quadratically affected total VFA (Q, P = 0.031) and ammonia (Q, P = 0.034), with a linear increment in acetate (L, P = 0.01) and isovalerate (L, P = 0.05) and reduction in butyrate (L, P = 0.05). Disappearance of neutral detergent fiber (NDF) and acid detergent fiber (ADF) was quadratically affected by levels of SRU, plateauing at 1% SRU. Inclusion of 1% SRU resulted in the highest amount of microbial nitrogen associated with feed particles (Q, P = 0.037). Responses in the efficiency of microbial protein synthesis fluctuated (L, P = 0.002; Q, P = 0.001) and were the highest for 1% SRU. In general, the result of this study showed that 1% SRU in combination with 0.6% urea increased NDF and ADF digestibility and total volatile fatty acid (TVFA) production.

The aim of this study was to evaluate the feeding behavior of lambs fed diets containing peach palm meal replacing maize (0, 10, 40, 60, and 85% DM). Thirty Santa Inês sheep with an average initial body weight of 21.6 ± 0.87 kg were distributed in a completely randomized design with five diets and six replicates. Feeding time in min kg–1 DM and min kg–1 NDFap increased by 34 min and 99.6 min, respectively, with each level of substitution of maize for the peach palm meal. Rumination and chewing times, in min kg–1 DM and min kg–1 NDF, also increased in response to the substitution of maize for peach palm meal. When expressed in min day–1, rumination and chewing activities decreased by 12.4 and 14.6 min, respectively, as the amount of peach palm meal in the concentrate was increased. The time spent idle increased linearly (P &lt; 0.05), by 14.6 min day–1, with the replacement levels, compared with the control diet. Peach palm meal in the composition of sheep diets reduces the intakes of dry matter and fiber and decreases the feed and rumination efficiencies. Replacing maize by peach palm meal increases the feeding time and rumination and chewing activities of feedlot lambs.

This study aims to analyze the digestibility of dry matter and organic matter of fermented sago pulp alternative feed on local sheep male weaning. Research conducted at Karang Rejo village farm, Stabat district, Langkat. This study in Maret 2016-Juny 2017. The design used was completely randomized design (CRD), with four treatments five replications. Each repeat consists of one local sheep male weaning with the average of body weight 8-10 kg. The treatment consisted of P1(consentrat with 50% sago pulp without fermented + forage), P2 (consentrat with 60% sago pulp without fermented + forage), P3 (consentrat with 50% sago pulp fermented + forage), and P4 (consentrat with 60% sago pulp fermented + forage). The variable were studied dry matter consumption, organic matter consumption, dry matter digestibility and organic matter digestibility. Results of analysis of variance show that the utilization of fermented sago pulp waste had highly significantly different effect (P<0,01) on dry matter consumption of treatment P1, P2, P3 and P4 is 486,38; 548,68; 604,69;and 671,11 (gr/head/day), and organic matter consumption is 469,34; 525,22; 582,42 and 644,40 (gr/head/day). And average of dry matter digestibility waste not significantly different effect (P>0,05) on value dry matter digestibility of treatment P1, P2, P3 and P4 is 79,04; 79,23; 78,59 and 78,23 (%), average of organic matter digestibility is 81,66; 81,43; 80,79 and 80,27 (%). Increasing use of fermented pulp sago increases the value of dry matter consumption and organic matter consumption in local sheep feed. Conclusions of fermented sago pulp can not to increase dry matter digestibility and organic matter digestibility, but fermented and non-fermented sago pulp can be given to sheep male weaning up to 60%, because the digestibility value of the two ingredients is above 70%.

ABSTRACT This study aimed to assess the effects of yellow grease supplementation on the intake, digestibility, and nitrogen balance in sheep. Twenty Santa Inês lambs with a mean age of 95 ± 10 d and body weight of 19.29 ± 3.17kg were evaluated in a completely randomized design. The diets were supplemented with oil at concentrations of 0, 20, 40, 60, and 80 gkg-1 of dry matter (DM) of the concentrate. The diets were based on roughage and concentrate (50:50). The experimental period lasted 19 d and included 14 adaptation days and five collection days for the total supplied diet, orts, feces, and urine. Supplementation with yellow grease had no significant effect on the intake of DM, crude protein (CP), neutral detergent fiber (NDF), or non-fiber carbohydrates (NFC). However, the ether extract (EE) intake increased linearly with supplementation of yellow grease. Moreover, no effect was observed for DM, CP, NDF, and NFC digestibility and nitrogen balance. EE digestibility increased linearly with the yellow grease dietary supplementation. Thus, sheep dietary supplementation with yellow grease may be used at a level of up to 80 gkg-1 of DM of concentrate without impairing nutrient intake and digestibility.

The aim of this research was to find the interaction between supplementation of Hibiscus tilliaceus leaf meal (HLM) and dry matter (DM) ratio of ammoniated rice straw (ARC) and concentrate on DM intake (DMI), organic matter digestibility (OMD) and Sumba Ongole (SO) cattle performances. Eighteen of SO male cattle with the average of 21.67 Kg ±17.62 early body weight were used in this research. Completely Randomized Design with factorial pattern which consists of two factors (2 x 3) was applied. Those factors were DM ratio of ARC and concentrates of 35: 65 (I1) and 30: 70 (I2); and the concentrates that supplemented with HLM level (ppm) of 0% (W1), 0.24% (W2), and 0.48% (W3). DMI of each cattle was 3.3% of body weigh. HLM supplementation and ARC and concentrates DM ratio as well as their interaction were not significantly effected (P> 0.05) on OMD, and SO cattle performances. OMD tended to increase at I1W2 and performances tended to be better at W3 both I1 (1.27 kg ± 0.28 and 17.21% ± 0.11) and I2 (1.26 kg ± 0.08 dan 19.87% ± 0.03). HLB supplementation could not be recommended to improve OMD and SO cattle performances.

The experiment was conducted on 12 female goats with average bodyweight of 13±1.28 kg, designed in a completely randomized design with four treatments and three replicates to evaluate replaceing Operculia turpethum levels on growth of Bach Thao goats. Four treatments had the following convolution rate: 0% (OT0, control), 25% (OT25), 35% (OT35) and 45% (OT45). Concentrate is 0.15; 0.2 and 0.25 kg dry matter/head/day. Crippling rates (25, 35 and 45%) were calculated on the basis of 5% body weight and feathered grass was fed ad bilitum. The results showed that the average bodyweight gain of goats in treatments OT0, OT25, OT35 and OT45 was 77; 104; 111; 91 g/head/day, in which OT35 treatment had the highest bodyweight gain . DM intake was significantly different in the treatments. Feed conversion ratio was the lowest at OT25 (7.89) and the highest at OT0 (9.38) but no significant difference. The OT35 treatment achieved the best bodyweight gain and economic efficiency in the brackish replacing levels in the Bach Thao diets

Hydrolysis Conditions

This study aimed to evaluate the digestibility and nitrogen balance (NB) of lambs fed sugarcane hydrolyzed under different conditions. Fifteen Ile de France lambs at, on average, 23.5kg of body weight were evaluated. Treatments were: in natura sugarcane (IN), sugarcane hydrolyzed using 0.6% calcium oxide (CaO) under aerobic condition (AER), and sugarcane hydrolyzed using 0.6% CaO under anaerobic condition (ANA). Therefore, a completely randomized design was constituted with five replicates per treatment. Treatments were supplied to animals along with concentrate. Both hydrolysis conditions aimed to alter the sugarcane fermentation pattern, therefore improving fiber digestibility. Lambs were housed in individual pens and fed with diet allowing 10% of refusals. Refusals, feces and urine were sampled daily during five days. They were collected to determine the digestibility and NB. A higher digestibility of neutral detergent fiber corrected for ash and protein (57.05%), organic matter (85.39%), hemicellulose (72.09%), NB (29.46g day-1 and 2.78g kg-0.75 day-1) and rate of nitrogen absorbed (3.00g kg-0.75 day-1) were observed for lambs fed with ANA than for those fed IN (41.17%, 73.76%, 53.80%, 21.39g day-1, 2.00g kg-0.75 day-1 and 2.22g kg-0.75 day-1, respectively). As roughage, ANA in the lamb diet, optimizes the nitrogen balance and is more efficient to improve the digestibility of some nutrients compared to IN. Whereas AER was as efficient as ANA and IN

Abstract This study aimed to evaluate energetic feedstuffs regarding chemical composition, in situ ruminal degradability of dry matter (DMD), ruminal kinetics and ruminal disappearance rate of dry matter. Seven feedstuffs (treatments) were evaluated: ground corn, ground oat, ground barley, wheat bran, soybean hull, malt root and corn germ, in a completely randomized design of four repetitions each. Two bovines ruminally cannulated were used for incubation, wherein each treatment was subjected to seven periods of exposure to the rumen (0, 3, 6, 9, 12, 18 and 24 hours). Among the evaluated feedstuffs, soybean hull had the highest neutral detergent fiber (NDF) content (68.91%) and the lowest DMD at 24 h (64.91%). Ground barley and ground corn contained the lowest content of soluble fraction (SF) (26.34 and 28.7%, respectively), among which ground barley had the highest DMD at 24 h (90.48%) and therefore showed the highest rumen disappearance rate (2.50%.h-1) by combining both parameters, while the ground oat presented the highest SF (47.75%) and the lowest rumen disappearance rate (1.09%.h-1).
