Nutritional parameters of lambs fed extruded ration with different roughage to concentrate ratios

The objective of our study was to compare the intake and digestibility of dry matter and nutrients, and the nitrogen balance, of lambs fed extruded ration with different roughage (R) to concentrate (C) ratios. The experiment was carried out at the Federal University of Uberlândia (UFU), Experimental Farm Capim Branco, from 7 December 2016 to 6 January 2017. Ten lambs (Santa Inês × Dorper) aged between four and five months, and with a mean weight of 25.9 ± 2.8 kg, were used. The animals were placed in metabolic cages equipped with a feeder, drinking fountain, and salt shaker, and which had a wooden slatted floor. The treatments consisted of extruded ration with 30R:70C or 70R:30C. Treatments were distributed in a randomised, complete block design, with each treatment being performed twice and with ten replications. The experiment was carried out in two blocked stages. Differences in the means of treatments were evaluated by Tukey’s test at a significance level of 5%. Intake and digestibility of dry matter and nutrients, water intake by animals, and nitrogen balance were also analysed. The 30R:70C treatment resulted in a lower intake of dry matter, crude protein, neutral detergent fibre, acid detergent fibre and hemicellulose, and caused higher dry matter and neutral detergent fibre digestibility. The 30R:70C treatment also resulted in a lower intake and faecal excretion of nitrogen, consequently establishing a higher ratio between retained and ingested nitrogen. In conclusion, the ration with 30R:70C results in lower intake, and better utilisation of nutrients by the animal.

During the dry season, forages are low in quantity and quality; hence lacks the essential nutrients that are prerequisite for growth in ruminants, suggesting a supplemental feeding. Thus, this study was conducted to investigate the dry matter intake, nutrient digestibility and nitrogen balance in growing Red Sokoto bucks fed Sorghum bicolor hay supplemented with concentrate. Eight growing Red Sokoto bucks with average body weight of 15±1.0 kg were randomly allotted to two dietary treatments containing S. bicolor hay/concentrate mixture (100:0 and 60:40). The bucks were individually fed at 3.5% body weight daily for a period of 21 days in a completely randomised design with four replicates per treatment. The parameters measured were dry matter intake, water intake, amount of faeces voided, volume of urine and costs of feeding. Total dry matter intake (424.64g/day) was significantly (p<0.05) higher in 60:40 dietary treatment than 100:0 treatment (353.57g/day). The digestibility coefficients of crude fibre (92.34 %), acid detergent fibre (71.46 %) and neutral detergent fibre (69.77 %) were significantly (p<0.05) higher in Red Sokoto bucks fed Sorghum bicolor hay:concentrate ratio of 100:0 compared to bucks fed 60:40 diet with crude fibre (87.25 %), acid detergent fibre (59.67 %) and neutral detergent fibre (60.08 %) digestibility coefficient values. However, crude protein (78.49 %) and ash (70.04 %) digestibility coefficients in bucks fed 60:40 diet were significantly (p<0.05) higher than those fed 100:0 diet with 38.14 % crude protein and 21.45 % ash digestibility coefficients. There was an increasing trend (p<0.05) in all parameters measured when concentrate was supplemented. The nitrogen retained (7.55 g/day), nitrogen retained as % intake (68.76 %) and nitrogen absorbed as % intake (78.46 %) were significantly (p<0.05) higher in Red Sokoto bucks fed 60:40 diets when compared with that of 100:0 diet which recorded 0.69 g/day nitrogen retained, 23.87 % nitrogen retained as % intake and 38.15 % as nitrogen absorbed as % intake, respectively. Total costs per kg of feed (N78.13K) and costs of feeding per buck (N696.72K) were significantly (p<0.05) higher for 60:40 diet than 100:0 diet with N45.83K total costs per kg feed and N340.29K costs of feeding per buck. It is therefore, concluded that concentrate supplementation on Sorghum bicolor hay enhances its utilisation by growing Red Sokoto bucks in terms of increased dry matter intake, nutrient digestibility and nitrogen retention in Northern Guinea Savannah of Nigeria.

The bromatological composition and in vitro dry matter digestibility of millet cultivars were assessed for different nitrogen doses and two sowing seasons in the Ceres municipality of Goiás state, Brazil. The treatments consisted of three millet cultivars (ADR-7010, ADR-500 and BRS-1501), four nitrogen (N) doses (0, 50, 100 and 200kg ha-1 of N) and two sowing seasons. Three replicates and a randomised block design with a 3 x 4 x 2 factorial scheme were used. Two cuttings were performed in each season when plants reached an average height of 0.70 cm. No significant interactions were observed between or among cultivars for N doses and dry matter (DM), crude protein (CP), neutral detergent fibre (NDF) and acid detergent fibre (ADF) contents. The DM, CP, NDF and ADF contents were significantly different between N doses. The DM and CP contents increased as the N dose increased to 100kg ha-1. The maximum DM and CP contents were 11.14 and 22.53%, respectively. The NDF and ADF contents were higher in the control treatment (60.11 and 30.01%, respectively). In addition, the lowest ADF and NDF concentrations occurred at an N dose of 50kg ha-1(56.33 and 30.23%, respectively). The DM contents were higher for the February sowing, with an average of 10.59%. The highest CP and ADF contents were found for the December sowing (22.46 and 31.58%, respectively). No significant differences were found for millet cultivars, N doses or sowing seasons. A significant interaction was found between sowing season and millet cultivar. The BRS-1501 cultivar had a higher in vitro dry matter digestibility in the December/2010 sowing (73.88%).

An experiment was conducted to determine the biomass yield, chemical composition and in-sacco dry matter (DM) degradability of 10 cultivars (WRF-7, TSN-111, TYT-03, TYT-05, TYT-06, TYT-08, TYT-12, ITYN-10, ITYN-14 and ITYN-15) of triticale fodder. The fresh yield of different cultivars of triticale was ranged from 5.03 to 6.85 (t/ha). The organic matter (OM), crude protein (CP), acid detergent fibre (ADF), neutral detergent fibre (NDF), calcium (Ca) and phosphorus (P) contents of different cultivars of triticale were found 89.62 to 91.78 %, 21.34 to 25.99 %, 23.09 to 29.99 %, 46.77 to 50.80 %, 0.42 to 0.61 % and 0.33 to 0.41 %, respectively. The yield of DM and CP of different cultivars of triticale were varied from 0.77 to 1.44 (t/ha) and 0.193 to 0.351 (t/ha), respectively. Among different triticale cultivars the highest OM and CP contents were found in TYT-12 (91.78 %) and ITYN-10 (25.99 %), respectively. The highest NDF and ADF contents were found in ITYN-14 (50.80 %) and TYT-05 (29.99 %), respectively among different cultivars. The contents of Ca and P in ITYN-10 (0.61 %) and ITYN-14 (0.41 %), respectively were found to be the highest among the cultivars. Potential DM degradability observed in different cultivars of triticale was higher in ITYN-14 and TYT-05 (84.81 and 81.88 %, respectively) compared to others and relatively poor degradability was found in TSN-111 and TYT-03 (60.74 and 61.35 %, respectively). Therefore, it may be concluded that, the cultivar ITYN-10 will be the promising one due to comparatively higher fresh yield, organic matter (OM), crude protein (CP), neutral detergent fibre (NDF), calcium (Ca) and phosphorus (P) content and less acid detergent fibre (ADF) fraction cultivated for fodder production in Bangladesh.http://dx.doi.org/10.3329/bjas.v41i1.11972

ABSTRACT: The objective was to evaluate the intake and the apparent digestibility in sheep fed on marandu grass silages added with dehydrated barley. Twenty crossbred Santa Inês lambs were used, with a mean initial weight of 30±4.5 kg and mean age of 14±2 months. The experimental sheep were distributed into a completely randomized design and lining, with five treatments and four repetitions, with treatments levels of inclusion of 0, 10, 20, 30 and 40% natural matter of naturally dehydrated brewery residue for 36 hours to the marandu grass silage to feed the sheep. The evaluation period lasted 21 days, 15 for adaptation to the diets and 7 days for data collection. The data was submitted to analysis of variance, and when significant (P<0.05) the treatment means were analysed by regression. The inclusion of dehydrated barley to silage showed a linear increase in water intake (P<0.05), increased by 0.02% per unit of dehydrated barley. A quadratic effect was observed for the levels of dehydrated barley on the dry matter intake (DM), estimating a maximum consumption of 2.86% DM for silages containing 17.8% dehydrated barley. The crude protein intake (CP) behaved quadratically, with the maximum value estimated of 0.29% CP at a level of 22.5% dehydrated barley. Ether extract (EE) intake also exhibited quadratic behaviour (P<0.05), with the maximum value estimated of 0.2% EE at a level of 28.25% dehydrated barley. The regression study showed quadratic behaviour; with the maximum estimated value of neutral detergent fibre was 2.33% at a level of 34.58% dehydrated barley. No statistical significance was found for the intake of acid detergent fibre or organic matter (P>0.05). It was concluded that the addition of levels of 20 to 30% of dehydrated barley to silage resulted in a positive response for the dry matter intake, crude protein, Ether extract and neutral detergent fibre.

ABSTRACT This study aimed to assess the effect of nitrogen (N) and potassium (K) fertilisation on the forage accumulation and nutritive value of Urochloa ruziziensis during the summer of 2010/2011 and autumn, winter, spring and summer of 2011/2012. A complete randomised block design with four treatments (0, 120, 240 and 360 kg ha-1 year-1 N and K2O) and five replicates were used. The data were analysed under the PROC MIXED of SAS®. The following variables were evaluated: sward height; forage mass; forage bulk density; percentages of leaf blade dry matter, stem dry matter, and dead material dry matter; leaf blade:stem ratio; contents of dry matter and crude protein; in vitro digestibility of dry matter; neutral detergent fibre content; and lignin content of Urochloa ruziziensis. There was an interaction between the N and K levels of fertilisation and the season for all variables. In addition, there was a positive linear effect of the N and K levels of fertilisation on the forage accumulation rate, the crude protein content and the in vitro digestibility of dry matter and a negative linear effect these levels on the neutral detergent fibre and lignin contents during the spring and summer of 2011/2012. N and K fertilisation and the climate changes characteristic of each season jointly affected the accumulation and nutritive value of Urochloa ruziziensis. N and K fertilisation up to 360 kg ha-1 year-1 improved the forage accumulation and nutritive value of Urochloa ruziziensis.

Random Block Design

It was evaluated nitrogen compounds and microbial protein synthesis in heifers fed diets containing coffee hulls (0.0; 8.75; 17.25; and 26.25% of dry matter) replacing ground corn concentrate at the following levels of coffee hulls in the total diet dry matter: 0.0, 3.5, 7.0 or 10.5%. It was used 24 crossbreed heifers (7/8, 15/16 and 31/32 Holstein-Zebu), which were distributed in a random block design made up accordingly to the weight of the animals. Spot samples of urine were colleted aproximatelly four hours after morning feeding and were used to estimate microbial protein synthesis by using urine purine derivatives. It was not observed effect of coffee hull levels in the diet on total nitrogen intake (160 g/day) and nitrogen excretion in the urine (87.4 g/day). The inclusion of coffee hull in the diet linearly increased nitrogen excretion in feces, as well as nitrogen balance. There was linear reduction in urinary excretion of allantoin, in total purine derivative and absorbed purine, which reduced 0.715, 0.873, and 0.954 mmol/day to each coffee hull unity added to the concentrate, respectively. Coffee hull altered microbial protein synthesis, which reduced in 0.687 g/day to each coffee hull unity added to the concentrate. Reduction in microbial protein synthesis can reduce weight gain in heifers fed coffee hulls.

An experiment was conducted to evaluate the effect of growth, biomas yieds and nutritive value of Lablab purpureus, Centrosema pubescens and Mucuna pruriens under rain fed condition in Yola, Adamawa State, Nigeria. The field experiment was laid in a randomized complete block design with the plot divided into three main plots and replicated three times measuring 5x5m with inter and intra row spacings of 0.5m. The five harvesting stages are 6, 8, 10, 12 and 14 weeks, respectively. The growth in height increases with stage of growth and declined with reduction in rainfall. Higher growth were recorded in T3 (3.8 -354.8cm) followed by T2 (2.96-260.20cm) and then T1 (1.50-213.00cm) and the results were presented graphically. The result of the chemical composition of all the legumes showed that the crude protein decreases with stage of growth from weeks 6 -14 (14.40, 12.26, 10.65-10.08, 6.79, 6.49) and ADF and NDF (25.20, 32.15, 27.35-42.13, 40.33, 36.50 and 32.20, 54.45, 47.00- 51.24, 63.53, 66.33), respectively. The biomass yields were significantly different (P<0.05) for all the legumes at different harvesting stages T1 (2744.53-3186.93), T2 (2696.47- 3006.70) and T3 (2843.73-3147.63). It is therefore concluded that legumes could best be harvested between weeks 10 and 12 when the yield and quality are at levels to sustain the animals both for maintenance and production.
