The Mean

The mean retention time (MRT) of stained hay through the whole digestive tract and its digestibility were measured in Japanese sika deer (Cervus nippon) and were compared with those in sheep when lucerne (Medicago sativa) hay was fed at 10, 20 and 30 g/kg body-weight. The recoveries in faeces of plastic particles with five specific gravities were also measured in deer. MRT for deer was significantly shorter than that for sheep at 10 and 20 g/kg feeding levels. The digestibilities of dry matter, organic matter, and neutral-detergent fibre were significantly lower for deer than for sheep at 30, 30 and 10 g/kg feeding levels respectively. The recovery rates of plastic particles were increased, but the ruminated rates were decreased, with increasing specific gravity in deer. These results suggest that the lower digestibility of lucerne hay in Japanese deer may be due to a shorter MRT compared with sheep.

The Difference

The mean retention time of feed particles in the alimentary tract of sheep was measured by means of a stained-particle technique, when lucerne hay or a diet of wheaten straw + wheaten hay (1 : 1) was offered ad libitum. The levels of intake of the straw diet and lucerne hay were equivalent to 11.8 and 25.8 g organic matter/day/kg body weight. The mean retention time of particles in the entire alimentary tract when the straw diet was offered was 57.5 hr, this consisting of 36.3 hr in the rumen + omasum and 21.2 hr in the abomasum + intestines. The retention time in the rumen + omasum was calculated to consist of (a) 19.7 hr during which the particles were being degraded to a size at which transfer from the rumen could be readily effected, and (b) 16.6 hr of residence in the rumen + omasum as small particles. With lucerne hay, the retention times were shorter: small particles spent 10.8 hr in the rumen + omasum and retention time in the abomasum + intestines was 16.1 hr. It was calculated that only a small proportion of the difference between the straw diet and lucerne hay in organic matter intake could be attributable to differences between the diets in the rate of removal of finely divided particles of organic matter from the rumen.

The questing height (i.e. ambush height) of ticks on a plant plays an important role in host selection. To test the hypothesis that the questing height of ticks in a locality had adapted to the body size of the host in that locality, we examined the questing height of nymphs of the ticks, Haemaphysalis longicornis and H. mageshimaensis, at 7 locations in Japan. Sika deer, Cervus nippon, is the primary host of these ticks and there is considerable geographical variation in the body size of sika deer. Multiple regression analysis revealed that the questing height in the field was influenced by the height of the plants and by the body size of deer at a location. However, the questing height of ticks at some locations may have been constrained by the height of the plants and might not be the same as their intrinsic questing height. When ticks were placed in vertical glass tubes in the laboratory, the questing height of ticks from a locality was correlated with the mean body size of deer at that locality. Therefore, the prominent cue determining the questing height of H. longicornis and H. mageshimaensis seems to be the body size of the host deer.

SUMMARY It was evaluated the effect of feed supplementation at 0.4; 0.8 and 1.2% of body weight (BW) on intake and digestibility of crossbred goats finished on caatinga, in relation to crossbred goats not supplemented (0.0% of BW). Thirty-two crossbred, Anglo-Nubian goats were used, eight months old and with body weight of 18 ± 2.5 kg, organised into randomised blocks, which were kept on 37 hectares of caatinga from 7 h to 16 h. Intake of dry matter, organic matter, crude protein, ether extract, neutral and acid detergent fibre, total carbohydrates and total digestible nutrients was influenced (P<0.05) by the levels of feed supplementation, with linear increases of 202.31; 179.42; 25.05; 11.83; 35.79; 12.27; 142.63 and 166.79 g animal-1 day-1 respectively. There was a substitution effect (P<0.05) on dry matter intake when using feed supplementation at 0.7% BW. Feed supplementation resulted in positive linear effect (P<0.05) for digestibility of dry matter, organic matter, crude protein, ether extract, total carbohydrates, total digestible-nutrient content and digestible energy, with an increase of 17.15; 16.64; 19.07; 44.74; 15.15 and 17.56% for dry matter, and 0.69 Mcal kg-1 of dry matter respectively. Final body weight, total gain and average daily gain, showed a linear increase (P<.005) of 2.60, 3.09 and 0.036 kg per percentage point of each additional level of supplement. Feed supplementation increases the intake and digestibility of total dry matter and nutrients, a fact that makes greater performance possible, and recommends use up to a level of 0.7% BW to avoid any substitution effect.

The experiment goal was to determine the supplementation effect of katuk leaves meal and Zn bio complex on dry and organic matter consumption and digestibility of postweaning male of Ettawa Crossbred. The experiment used sixteen heads of the postweaning male of Ettawa Crossbred aged 4-5 months with an initial body weight of 9.01±1.85kg (CV 20.55%). Completely Block Randomized Design (CBRD) with 4 treatments and 4 replications were applied in this experiment. Those treatments were P0: Lamtoro + concentrate without katuk leaves meal and Zn biocomplex (control); P1: P0 + 5% katuk leaves meal (on the basis of forage dry matter)  and Zn bio complex; P2: P0 + 10% katuk leaves meal (on the basis of forrage dry matter) and Zn bio complex; P3: P0 + 15% katuk leaves meal (on the basis of forage dry matter) and Zn bio complex. Variables measured were dry matter (DM) consumption, organic matter (OM) consumption, DM digestibility, and OM digestibility. Average of DM  consumption were P0 (326.68 ±44.13g/h/d), P1 (351.68±63.47g/h/d), P2 (351.78±33.41g/h/d) and P3 (346.24±32.48g/h/d). Average of OM consumption were, P0 (300.38 ±41.14g/h/d), P1 (316.11±57.05g/h/d), P2 (315.54±30.83g/h/d) and P3 (309.21±29.00g/h/d). Average of DM digestibility, P0 (78.94 ±4.67%), P1 (78.77±9.54%), P2 (64.82±11.45%), P3 (75.38±14.56%). Average of OM digestibility, P0 (81.17±4.01%), P1 (80.77±8.69%), P2 (68.79±9.90%), and P3 (76.93±12.77%). The result of variance analysis showed that treatment has a significant effect (P<0.05) on dry and organic matter consumption but no significant (P>0.05) on dry and organic matter digestibility It can be concluded that supplementation of of katuk leaf meal (Sauropus androgynus L. Merr) at 5% up to 15% and Zn bio complex might increase dry and organic matter consumption of postweaning male of Ettawa crossbred.

Abstract. Suwignyo B, Arifin L, Umami N, Muhlisin, Suhartanto B. 2021. The performance and genetic variation of first and second generation tropical alfalfa (Medicago sativa). Biodiversitas 22: 3265-3270. This study aimed to compare the growth performance, nutrient content, seed viability, and genetic variation of first- and second-generation alfalfa (Medicago sativa L.). First and second-generation alfalfa seeds were obtained from the Forage and Pasture Science Laboratory, Department of Animal Nutrition and Feed Science, Faculty of Animal Science, Universitas Gadjah Mada (UGM), Yogyakarta, Indonesia. First generation alfalfa (F1) seeds were obtained from cross breeding of two different parental alfalfa varieties, namely, Canadian and local. The second-generation (F2) seeds were obtained from plants of the first-generation alfalfa (F1). A randomized design experiment was conducted using the two types of alfalfa (first- and second generation). Alfalfa from Canada as female parent was used as the baseline in the genetic masker test. Seeds were planted in a polybag, watered twice a day, and received 12 hours of daylight and 4 hours of artificial light. Plants were then harvested 8 weeks after planting by cutting the plant canopy. Genetic variation was examined using the Inter Simple Sequence Repeat (ISSR) method followed by descriptive analysis. Germination, plant height, dry matter content, organic matter, and crude protein were assessed as variables using a Student’s T-test. Our results showed that germination, plant height, leaf color, and nutrient content (dry matter, organic matter, and crude protein) of the first- and second-generation alfalfa plants were not significantly different. However, the second-generation alfalfa demonstrated better seed viability than the first generation plants, then it can be categorized as a new genotype (tropical alfalfa) based on genetic variation analysis.

To increase the productivity of the sheep, the feed have a certain quality with the mix of worm flour. This research aims to determine the influence of the use of worm flour (Lumbricus rubellus) concerning to dry and organic matter digestibility lokal male sheeps feed. This research was conducted in the enclosure of research at the Faculty of Agriculture, Animal Husbandry Department of the Universitas Sebelas Maret Surakarta which is located in the Village Jatikuwung, Gondangrejo District, District Karanganyar. Research was conducted from December 28th, 2008 to February 22nd, 2009 using the 12 local male tail sheep with body weight on average 13.82 ± 0.73 kg / head. Feed given at 6% of body weight consist of a concentrate forage and comparison with 70:30 per cent (basic dry matter). Utilized of the concentrate made of a mixture that consist of bekatul, oilcake soybean, corn flour, worm flour, and premix while forage given a field grass. Feed treatment used field grass 70%, concentrate 30% (P0); field grass 70%, 28% concentrate, worm flour 2% (P1); field grass 70%, 26% concentrate, worm flour 4% (P2) and 70% field grass, 24% concentrate, worms flour 6% (P3). Experimental design used was the Complete Random Design (CRD) pattern, the direction of the 4-level treatment (P0, P1, P2, and P3). Each treatment consist of 3 test replications and the replications each of one local male sheep. Parameter observed: dry matter consumption (DMC), organic matter consumption (OMC), dry matter digestibility (DMD), and organic matter digestibility (OMD). Results of research indicate that the average of the four treatment (P0, P1, P2 and P3) respectively for the dry matter consumption 858.35, 876.57, 881.55 and 887.58 (grams/ head/ day), organic matter consumption 670.32, 682.04, 686.16 and 689.03 (grams/ head/ day), dry matter digestibility 55.17, 59.51, 57.19 and 58.84 percent and organic matter digestibility 66.28, 69.09, 67.21 and 68.12 percent.

Abstract The objective of this study was to evaluate the effects of different energy sources on performance, and carcass characteristics in hair lambs finished in feedlots. Twenty-eight hair lambs with an initial body weight (BW) 20.8 ± 3.01, were randomly assigned to one of four dietary treatments included with seven lambs per treatment. The dietary treatments included an energy source included at 18% Dry matter: S. spectabilis flour (SF), palm kernel (PK), corn bran (CB) and rice bran (RB) in a diet based in corn silage, ground corn, soybean meal formulated to 13.0% PC and 2.6 Mcal/Kg of DM. The feeding trial was performed for 13 weeks. Water was allowed ad libitum. Animals were slaughtered after the feeding trial, and the carcasses were kept at 4°C for 24 h under Colombian standard guidelines. Data were analyzed by using the ANOVA procedure, SAS version 9.1 to perform a randomized complete experiment with four diets. For each studied variable, the mean and standard error of the mean (SEM) were calculated and differences between means were evaluated Using Tukey′s Test (P ≤ 0.05). Final body weight, hot carcass weight, cold carcass weight, hot dressing carcass (%), and cold dressing weight (%) were not different between the four treatments (P &gt; 0.05). Dry matter intake was superior to the S. spectabilis flour (P &lt; 0,001). Feed efficiency was higher in the CB and RB treatments (P &lt; 0,05). These results indicate that the inclusion of S. spectabilis and palm kernel could improve the dry matter intake and corn bran and rice bran the feed efficiency without effects on carcass characteristics

An experiment was conducted to examine the effect of restricted feeding under two lighting systems during the rearing period on the initial laying performance of broiler type pullets. The rearing treatments were imposed at nine weeks of age, removed at 22 weeks and the trial was discontinued at 36 weeks of age. The feeding treatments (restricted versus ad lib.) were arranged factorially with the lighting treatments (decreasing versus increasing). Birds reared on restricted feeding reached sexual maturity 16 days later than full fed birds, ate 17 per cent less feed to 22 weeks and gained seven per cent less in body weight to 24 weeks of age and ten per cent less to 36 weeks. Birds reared under the decreasing lighting regime reached sexual maturity at the same age as those reared under increasing lighting, ate five per cent more feed during the rearing and laying periods and gained five per cent more in body weight to 24 weeks. The mean weight of eggs laid between 24 and 34 weeks of age from pullets subjected concurrently to decreasing lighting and restricted feeding was approximately two grams heavier than that of the other three treatment combinations. Mean egg weight was one gram greater in the restricted than in the full fed group, although the difference was not statistically significant. Laying mortality was lower in the restricted fed group than in the full fed group.

1. In a number of experiments voluntary food intake of three low-quality roughages, either alone or supplemented with rumen-degradable nitrogen and sulphur and minerals, was measured in Brahman (Bos indicus) and Hereford (Bos taurus) steers. The chaffed hays were Spear grass (Heteropogon conform) (6.2 g N/kg organic matter (OM)), Pangola grass (Digitaria decumbens) (7.9 g N/kg OM), and Pangola grass (12.0 g N/kg OM). Rumen characteristics relating to rate of fluid outflow from the rumen were also determined.2. There was no significant difference between breeds in the dry-matter intakes of the unsupplemented diets which ranged from 11.3 to 17.8 g/kg body-weight (BW) by Herefords and from 11.8 to 16.1 g/kg BW by Brahmans.3. Supplementation of Spear grass with N and S significantly (P < 0.05) increased intake by Herefords (24%) but not by Brahmans. When the lower-N Pangola grass was supplemented there was a significant increase in intake by both breeds with the magnitude of the response in Herefords (42%) (P < 0.001) being greater than that in Brahmans (15%) (P < 0.05). The intakes of both the supplemented Spear grass and the lower-N Pangola diets were significantly (P < 0.05) greater by Herefords than Brahmans. There was no breed difference in intake when the higher-N Pangola grass was supplemented. Both breeds recorded an 8% intake response to supplementation, although the increase was only significant (P < 0.05) in Herefords.4. The mean retention time of fluid in the rumen on the unsupplemented Pangola grass diet of lower N content was 12.7 h in Brahmans compared with 17.5 h in Herefords (P < 0.01). When the higher-N Pangola was fed, both alone and supplemented, the mean retention times were similar on both diets (10.5 and 9.9 h for Herefords; 9.5 and 8.1 h for Brahmans for unsupplemented and supplemented diets respectively).5. Plasma urea concentrations were higher in Brahmans than in Herefords on all diets. Rumen ammonia concentrations were significantly (P < 0.001) higher in Brahmans than Herefords when the lower-N Pangola grass diet was unsupplemented.6. The intakes and the variable intake responses to supplementation between breeds and diets are discussed in relation to a number of animal and dietary factors.
