SUMMARY

This research was conducted for one year at Chittagong Veterinary and Animal Sciences (CVASU)Fodder Research Field and at the Animal Nutrition Laboratory to produce maize fodder and silage andevaluate them and estimate the nutritive value of unconventional feed resources. The maize fodder wascultivated under four different treatment groups. It was observed that the green fodder biomass, drymatter and botanical fractions of maize were dependents on the dose level of sheep and goat manure withinorganic fertilizers. The treatment receiving sheep and goat manure @ 10 t/ha produced higher greenfodder yield (30.30±.07 t/ha) and dry matter (9.0±0.28 t/ha) than the other treatments. Three types ofsilage were prepared in bag and drum. The bag silage was spoiled due to unsystematic preparationmethod. However, the drum silage, the silage 3 (maize with molasses and urea) showed highest pH (4.69),crude protein (CP) (10.50%), ether extract (EE) (4.05%), nitrogen free extract (NFE) (41.63%) and metabolisable energy (ME) (1992 kcal/kg) than other silage. All three types of drum silage were good butconsideration of pH and nutrients composition the silage prepared with maize fodder with molasses wasgood than others. Different unconventional feed, such as tree leaves, seeds and byproduct were collectedand analyzed for their nutritive values. It was noticed that the dry matter was highest in Krisnachura(34%), CP and energy in Dhaincha (26% and 2594.44 kcal/kg), NFE in water hyacinth than other treeleaves. The rain tree seed was higher in DM (88.6%), CP (28.5%) , EE (10.5%) and energy (2794 kcal) thanother feeds. Rubber seed contained nutrient composition close to rain tree seed but husk containedhighest CF (48.5%) than other seeds. All studied tree leaves, seeds and byproduct can be used asalternative feed resources for livestock. Furthermore, Dhaincha, ipil-ipil, rain tree and rubber seed couldbe used as livestock and poultry feed ingredient due to its high protein and energy value

SUMMARY

The field experiment was conducted during 2008 to 2010 at Bikaner to find out an efficient agri-silviculture or silvi-pastoral model for cultivable wastelands of arid tropics of India. Three multi-purpose tree species viz., khejri (Prosopis cineraria), ardu (Ailanthus excelsa) and rohida (Tecomella undulata) suitable for arid tropics were planted in July 2008 and annual grain legumes viz., clusterbean (Cyamopsis tetragonoloba), and mothbean (Vigna aconitifolia) in kharif 2009 and 2010, while pasture grasses viz., sewan (Lasiurus sindicus) and anjan (Cenchrus ciliaris) grasses once in July 2009. Results indicated that tree species had no adverse effect on growth and grain/fodder yields of crops and grasses in both the years. Similarly, annual crops/grasses did not exerted any significant effect on the growth attributes of any tree species. Among grain crops and grasses, clusterbean recorded higher grain (0.82 and 0.91 t/ha) and straw (1.97 and 2.47 t/ha) yields over mothbean. Whereas, sewan grass out-yielded anjan grass with green fodder yield of 12.1 and 16.7 t/ha, and dry matter yield of 4.68 and 6.02 t/ha during 2009 and 2010, respectively. Computation of clusterbean equivalent yields (CEY) showed that CEY recorded with clusterbean (1.31 t/ha) and mothbean (1.28 q/ha) were statistically at par but significantly higher over both grass species. Slight higher values of net returns and B:C ratio were observed with khejri plantation (Rs. 11,697 and 1.78) compared to other tree species, while among crops clusterbean gave maximum values of net returns Rs. 16,837 and B:C ratio 2.05. Organic carbon (%) and available N, P & K contents of soil were substantially improved under all treatments in comparison to initial soil fertility status. Thus, study suggests that growing of clusterbean or mothbean with any multi-purpose tree species viz., khejri, ardu and rohida plantation holds promise to provide higher and economical grain productivity with improved fertility status of soil under agri-silviculture system in arid tropics of Rajasthan.

SUMMARY

A field experiment was conducted 2006-2011 on sandy loam soil at Central Research Farm of Indian Grassland and Fodder Research Institute, Jhansi to find out the response of Guinea grass-legumes intercropping to weed control in semiarid rainfed conditions. Intercropping of Stylosanthes seabrana with Guinea grass produced significantly higher total green and dry forage yields (25.10 and 6.68 t/ha) than Clitoria ternatea (19.10 and 5.41 t/ha), Macroptillium atropurpureum (20.17 and 5.60 t/ha) and S. hamata (23.36 and 6.29 t/ha). Intercropping of S. seabrana with Guinea grass also resulted in significantly higher total crude protein yield (582.0 kg/ha) as compared to C. ternatea (457.7 kg/ha) and M. atropurpureum (474.9 kg/ha). In weed management practices, hand weeding 35 days after sowing in 1st year and 25 days after onset of monsoon rain from 2nd year onwards recorded significantly higher green forage, dry forage and crude protein yields of both Guinea grass (16.48 and 5.02 t/ha and 344.0 kg/ha) and legumes (9.05 and 2.0 t/ha and 271.8 kg/ha) than weedy check, pre-emergence application of pendimethalin @ 0.75 kg a.i./ha and weeding with weeder cum mulcher. Intercropping of S. seabrana with Guinea grass also resulted in significant improvement in organic carbon (0.48%) and available nitrogen (228 kg/ha) than C. ternatea and M. atropurpureum. Available nitrogen (226.2 kg/ha), phosphorus (9.91 kg/ha) and potash (195.8 kg/ha) were also significantly increased in hand weeding plots than weedy check (211.3, 9.05 and 179.1 kg/ha).

SUMMARY

A field experiment was conducted at Ranchi (Jharkhand) to study the effect of tillage and nutrient management on fodder oat during rabi seasons of 2010-11 and 2011-12. Results showed that conventional tillage recorded higher green (354.6 q/ha) and dry fodder (78.7 q/ha) yield, higher gross returns (Rs. 79,689/ha), energy output (142985 MJ/ha) net energy returns (129471 MJ/ha) and energy use efficiency (11.7) over zero and minimal tillage. Zero tillage recorded higher B : C ratio (2.5) over minimal and conventional tillage, while net returns (Rs. 54,660/ha) and conventional tillage (Rs. 55,094/ ha) were at par. Among the nutrient managements, 125 per cent RDF recorded significantly higher green fodder yield (375.1 q/ha) as well as gross returns (Rs. 83,904/ha), net returns (Rs. 59, 353/ha), B: C ratio (2.41), gross energy output (146069 MJ/ha), net energy output (132245 MJ/ha) and energy use efficiency (10.56). Application of biofertilizer at 75 per cent RDF was as good as 100 per cent RDF in terms of GFY, DFY, economics and energetics. Thus, in order to produce highest green herbage conventional tillage at 125 per cent RDF is most appropriate and application of biofertilizer (PSB+Azotobacter) saves the 25 per cent of inorganic fertilizer in fodder oat.

SUMMARY

A varietal evaluation trial on Lucerne (perennial) (Medicago sativa) was conducted at 9 locations under three different agro-ecological zones viz., Northwestern (NW), Central (CT) and South (SO) zones of India during 2007-08 to 2009-10. Three entries of Lucerne (BAIF Lucerne-1, Anand- 21 and Anand 22) were evaluated along with two national checks viz., RL 88 and Anand-2 for assessing their fodder yield potential and quality parameters at CCS HAU, Hisar. The same set of entries was also tested at eight different locations distributed in the three zones for fodder trial. The highest green fodder yield pooled over three years (1067.3 q/ha) was recorded at Coimbatore in south zone followed by Rahuri (996.4 q/ha) and Urulikanchan (967.1 q/ha) in the central zone whereas, the highest pooled dry matter yield (216.7 q/ha) was recorded at Coimbatore in south zone followed by Rahuri (203.3 q/ha) and Urulikanchan (182.8 q/ha) in the central zone. Highest per day production of green fodder pooled over three years was recorded at Rahuri and Hisar (GFY, (q/ha/day – 4.8 and 3.0, respectively) followed by Ludhiana (2.6 q/ha/day). The genotype BAIF Lucerne-1 gave a slight increase of 3.1% for green fodder yield and 2.0% increase for dry matter yield as compared to the best check RL 88 over three years. The highest crude protein yield pooled over three years was obtained at Coimbatore (40.9 q/ha) followed by Rahuri (35.6 q/ha) and Urulikanchan (28.8 q/ha). Lucerne genotype Anand 22 gave high In vitro dry matter digestibility% (IVDMD%) pooled over two years (68.2%) as compared to the best check Anand 2 (67.7%). The Lucerne genotype BAIF Lucerne-1 gave NDF% (43.8%) as compared to the best check RL 88 (45.2%) whereas BAIF Lucerne-1 gave ADF% (33.5%) as compared to the best check RL 88 (38.3%). Genotype BAIF Lucerne-1 gave high DDM yield (81.5 q/ha) which was comparable to the best check RL 88 (80.5 q/ha). Data reveals that Southern zone represented by Hyderabad, Coimbatore and Mandya gave higher green fodder and dry matter yields, plant height and production efficiency thereby indicating that climatic and edaphic conditions are very suitable for Lucerne as compared to Central Zone and North West Zone.

SUMMARY

Combining ability for various quantitative traits viz., plant height, leaf length, leaf width, number of leaves per plant, leaf : stem ratio and green fodder yield per plant were studied through (5 x 9) line x tester mating design. Highly significant gca and sca variances on pooled basis for the traits indicated that sufficient variability exists for gca effect in the parents and that for the sca effect in the crosses. Higher and significant sca variances on pooled basis suggested a higher non-additive gene action for these traits. Parents J-1006 and African Tall among females and GWC-0512, GWC-0401 and GWC-0511 among males were found to be the best general combiners. The hybrids viz., IC-130726 X GWC-0512, IC-107121 X GWC-9603 and IC-130726 X GWC-9603 were found to be the best specific crosses for green fodder yield per plant and, therefore, these can be further exploited for selection of hybrids and transgressive segregants.

SUMMARY

A field experiment was conducted during summer season of 2011and 2012 on sandy loam soil at S. D. Agricultural University, Sardarkrushinagar to study theresponse of multi-cut summer forage pearlmillet (Pennisetumglaucum) to varying levels of irrigation and nitrogen under semi-arid condition of Gujarat. Twelve treatment combinations comprised four levels of Irrigation scheduling (0.6, 0.8, 1.0 and 1.2 IW: CPE) and three levels of Nitrogen (100, 150 and 200 kg N ha-1). The pooled results showed that irrigation levels at 1.2 IW: CPE ratio showed significant influence on growth attributes viz., plant height, number of tillers and leaf: stem ratio. The irrigation at 1.2 IW: CPE ratio resultedsignificantly higher green fodder (1192.34 q ha-1) and dry matter yield (288.37q ha-1)over other levels of irrigation. However, maximum water use efficiency (86.07 kg ha-1) was recorded with irrigation at 0.8 IW: CPE ratio. The net realization (RS.93963 ha-1) and B: C ratio (3.71) was recorded highest with Irrigation at 1.2 IW: CPE ratio. The N levels had significant effects on all the growth parameters like the plant height, number of tillers and leaf: stem ratio. Application of 200 kg N ha-1 gave significantly higher green forage yield (1145.19 q ha-1), dry matter yield (249.74 q ha-1), WUE (87.66 kg ha-1),net realization (RS.83015 ha-1) and B: C ratio (3.86) over 150 and 100 kg N ha-1. Consequently for higher productivity and profibility of multi-cut summer forage pearlmillet, it should be grown with irrigation given at 1.2 IW: CPE ratio and fertilized with 200 kg N ha-1.

SUMMARY

The study was conducted to find relationship of residual feed intake (feed efficiency parameter) with various blood metabolites in growing Sahiwal female calves. Healthy Sahiwal female calves (n=18) were selected and fed total mixed rations consisting of wheat straw, berseem (Trifolium alexandrinum) and concentrate mixture (mesh, BIS type-I) according to their body requirements. Net feed intake and body weights were recorded at regular intervals. Residual feed intake (RFI) values were calculated for individual calves and they were designated low RFI group with negative (n= 9; RFI= -0.14 kg/ d) and high RFI group with positive (n= 9; RFI= +0.14 kg/d) RFI values. Low RFI consumed less (P<0.05) dietary DM compared to high RFI group (2.56 vs 3.02kg/100 kg B.wt.) while gaining similar body weights (0.48 and 0.47 kg/d) indicating higher efficiency of feed utilisation in the former group. Low RFI group showed better feed conversion ratio (20.29% lower), compared to high RFI group (5.52 and 6.64 kg DM consumed/kg gain). The values of blood glucose (56.71 and 59.14 mg/dl); total plasma protein (7.32 and 7.54 g/dl) and growth hormone (4.37 and 4.29 ng/ml) were similar in both groups. Low RFI group possessed higher (P<0.05) values for creatinine (1.52 vs 1.26 mg/dl) and IGF-1 (140.40 vs 122.49 ng/ml). On the contrary, the levels of aspartate aminotransferase (118.74 vs 97.51 IU/L) and BUN (22.03 vs 18.14 mg/dl) were higher in high RFI group compared to low RFI group.

SUMMARY

The experiment was conducted at Hisar during kharif season of 2011 with an objective to see the effect of different production factors on the NPK content and their uptake as well as quality of pearl millet in terms of protein content. Eight different treatments i.e. T1- Full Package & Practices [RDF (125 kg N + 62.5 kg P2O5 /ha) + ZnSO4 @ 25 kg /ha + biofertilizer biomix (Azospirillum + PSB) + thinning and gap filling + weeding and hoeing (20 and 35 DAS) + irrigation] , T2: T1-RDF (N and P), T3: T1- ZnSO4 @ 25 kg /ha, T4: T1- biomix, T5: T1- Thinning and gap filling (19 DAS), T6: T1- Weeding and hoeing (20 and 35 DAS), T7: T1- Irrigation and T8: Control were laid out in randomized block design with three replications. Non adoption of individual factors Recommended Doze of Fertilizer (T2), ZnSO4 (T3), biomix (T4), thinning and gap filling (T5), weeding and hoeing (T6) and irrigation (T7) caused a decrease in grain yield by 32.8, 12.2, 7.7, 16.7, 30.1, 20.2, 48.0 (control) per cent and stover yield by 22.7, 7.9, 4.0, 10.0, 18.9, 16.0 and 32.2 per cent (control) than T1 (FPP), respectively. Among all the treatments, T1 recorded significantly higher N, P, K and Protein contents and their uptake in grain as well as in stover. Nitrogen content in grain increased significantly from 1.66% under control (T8) to 1.84% in T1 and followed by T4 (1.82%), T3 (1.82%) and T5 (1.79%). The phosphorus content also increased from 0.24% (T8) to 0.31% (T1) in grain whereas potassium content in grain was lowest under T8 (0.53%) and highest under T1 (0.60%) treatment. The total N, P and K uptake was found highest in T1 (129.78, 26.47 and 308.77 kg ha-1, respectively). The protein content in grain also significantly increased from 10.4% (T8) to 11.5% in T1 and followed by T4 (11.4%) and T3 (11.3%) treatments. The present study clearly indicated that non adoption of individual factors i.e. recommended dose of N & P and weeding and hoeing caused a maximum decrease in grain yield by 32.8 and 30.1 per cent and stover yield by 22.7 and 18.9 per cent than full package practices, respectively. The adoption of full package & practices resulted in the higher N, P, K and content (%) and their uptake (kg/ha) in grain and stover.

SUMMARY

A field experiment was conducted during the zaid season of 2013 at Udaipur, Rajasthan on clay loam soil to assess the effect of fertility levels on multi-cut genotypes of forage sorghum. Among genotypes, fodder produced by genotype SPH 1697 accumulated significantly higher nitrogen, phosphorus and potassium in both the cuttings as well as total compared to genotypes SPH 1698, CSH 20 MF, CSH 24 MF and SSG 59-3. The multi-cut genotypes resulted in negative nitrogen and positive phosphorus and potassium balance over initial status. The crop fertilized with 100 per cent RDF accumulated significantly higher quantum of nitrogen, phosphorus and potassium in fodder during both the cuttings thereby total over control and lower fertility levels. The nitrogen, phosphorus and potassium status of soil after crop harvest was significantly improved with the application of 75 and 100 per cent RDF. Further crop under the influence of 50, 75 and 100 per cent RDF reduced net nitrogen loss but increased net gain of phosphorus and potassium in soil over initial.

SUMMARY

A field experiment was conducted at the Research Farm of the Department of Agronomy, Punjab Agricultural University, Ludhiana during the summer season of 2011. The soil was loamy sand in texture, slightly alkaline in soil reaction (8.0), low in organic carbon (0.33%) and available N (130 kg/ha), high in available P (28.5 kg/ha) and medium in available K (240 kg/ha). The experiment comprising 12 treatment combinations viz., three main plots (farm yard manure at 0, 12.5 and 25 t/ha) and four nitrogen levels in sub-plots (0, 40, 80 and 120 kg/ha) was laid out in split plot design with four replications. Quality components such as moisture content, crude protein, IVDMD and ash content were improved by application of farm yard manure 25 t/ha over 12.5 t/ha untreated and control. Interaction effects were also recorded at harvest stage of fodder crop in quality parameters such as moisture content, crude protein and IVDMD. Application of chemical fertilizers also improved the different quality parameters with increasing level of nitrogen up to the highest level (N120).

SUMMARY

Although, no micro nutrient has been applied to the crop but the effect of cutting management, nitrogen and phosphorus application on micro nutrients uptake was studied in the field experiment on oat. Results indicated that the highest zinc uptake by oat fodder (19.6 g/ha) was recorded when oat was cut 70 DAS (Day after sowing) followed by cut 60 DAS (17.6 g/ha) and then cut 50 DAS (15.7 g/ha). Whereas, highest zinc uptake by oat grain (24.7 g/ha) was recorded when oat was cut 60 DAS followed by cut 50 DAS (22.5 g ha-1) and least by cut 70 DAS (21.1 g a). Zinc uptake by oat straw was recorded highest when oat was cut 50 DAS (36.0 g/ha) followed by cut 70 DAS (30.5 g/ha) and then cut 60 DAS (35.0 g/ha). Similar trend was also observed in case of copper, manganese and iron uptake by oat fodder, grain and straw with different cutting managements. Zinc uptake by fodder, grain and straw increased significantly from 11.7, 19.3 and 31.4 to 23.4, 25.9 and 36.5 g/ha respectively, with the treatment N120+P60 over control, N40+ P20 and N80+P40 treatments. Application of nitrogen and phosphorus significantly increased the copper uptake in oat fodder, grain and straw from 7.2, 8.3 and 19.4 to 14.5, 11.1 and 22.6 g ha-1 respectively with N120+P60 over all other treatments. Manganese uptake by oat fodder, grain and straw also increased from 12.8, 15.6 and 34.2 to 25.5, 20.9 and 39.8 g/ha respectively with the application of N120+P60. Application of nitrogen and phosphorus significantly increased the iron uptake in oat fodder, grain and straw from 68.1, 144.7 and 182.4 to136.1, 193.8 and 212.5 g/ ha respectively with N120+P60.
