Growth Trial

Two growth trials and one digestibility trial with growing–finishing pigs are reported. In each growth trial, three groups of six barrows and three groups of six gilts were placed on each of the four dietary treatments of barley plus 15% soybean meal from approx. 23 kg body weight to approx. 84 kg body weight. The four treatments consisted of providing barley whole or ground, with the concentrates either mixed with the barley or supplied 6 h after the meal of barley. The feed allowance was slightly greater in the second trial than in the first. In the digestibility trial there were two sources of barley, each presented in three forms: whole, rehydrated acid-preserved whole, and ground, all mixed with the concentrates. Each diet was supplied at a restricted level or ad libitum to barrows at 28.9 kg and 57.0 kg mean body weight. In neither growth trial was there a significant effect of method of providing the ground barley on performance. With whole barley, feed efficiency was significantly inferior to that obtained with ground barley, being 20–37% lower when whole grain and concentrates were mixed, but only 5–16% lower when the whole grain and concentrates were provided separately. The digestibility trial indicated no differences between the two forms of whole grain, but a superior utilization of the ground grain. Dry matter digestibility of both forms of whole grain was significantly greater in the younger pigs than in the older pigs, increasing from 63.0 to 71.1% for the whole grain, and from 62.3 to 73.2% for the rehydrated acid-preserved whole grain. Dry matter digestibility of ground grain averaged 77.6% and was not affected by age of pig, but was significantly reduced by ad libitum feeding.

Basal Ration

Kids six months old and of mean liveweight 22 kg were offered a basal ration of barley and lupins (crude protein 15 .4%) supplemented with three levels of chopped hay (0, 13% of total intake and ad libitum). Supplementation of the basal ration with 13% hay increased total dry matter intake from 479 to 753 g/d (P< 0.001) and liveweight gain from 10 to 54 g/d (P<0 .01). Non-significant increases in total food intake and liveweight gains were achieved by supplementing with ad libitum hay; kids fed ad libitum hay actually consumed 26.9% of their diet as hay. They were then offered various mixtures of barley, oats and lupins with 13% chopped hay at near ad libitum feeding. Differences in intake or growth were not significant at P= 0.05 with kids growing at 74, 65 and 101 g/d for those fed barley, oats and lupins respectively. Results indicate that highest food intake was obtained when 13% chopped hay was added to whole barley grain rations.

Abstract The aim of the study was to determine the effect of the limitation of energy intake by restrictive dry matter intake in the faroff part (from -56 d to -22 d) of dry period on the colostrum quality and the calf immunological status. Thirty-eight Polish Holstein- Friesian Black and White multiparous cows and their calves were randomly allotted to one of the two dietary treatments in the far-off period. In group ADLIB, diet was offered ad libitum (2.0% body weight), while in group REST, dry matter intake was restricted to 1.5% of body weight. Lowered feed intake in the far-off period did not have a statistically significant influence on the quality of colostrum. On the 3rd d of calves’ life, serum concentrations of immunoglobulins, albumins, globulins, total protein, and IGF-1 were not affected by treatments of dam in the far-off period. The concentrations of total Ig and G and A immunoglobulins of 21-day-old calves from cows fed ad libitum during the far-off period was found to be significantly lower compared to REST group. No significant differences in birth weight and growth rate during the first 21 d of life were found. Limiting maternal diet in far-off period did not affect negatively colostrum quality and calves` immune response during early stages of their life.

Chopped Grass

SUMMARY1. Four groups of eight castrated male lambs, weighing initially about 37 kg, were fed ad libitum for 18 weeks on: C, chopped dried grass throughout; P, pelleted grass throughout; C/P (or P/C), the two forms alternated every 3 weeks; or C + P, both forms on offer.2. Daily dry-matter intake (g/kg W0·75) was 58·2 for treatment C and 814 for treatment P; thus the long-term difference in intake was 40%. However, in the alternated sheep, dry-matter intake was 53·6 g/kg W0·75 for chopped grass and 86·5 g for pelleted; this short-term difference (61%) was significantly greater than the long-term difference. Dry-matter intake for treatment C+P was 84·9 g/kg W0·75; after the first week, chopped grass comprised only 10% of this. Dry-matter digestibility coefficients (%) were: C, 740; P, 61·4 and C+P, 62·0.3. The sheep were killed in week 19 and the dimensions of digestive organs and their contents were adjusted to an animal of 50 kg empty body weight. The weight of the reticulo-rumen was greater for C (1·30 kg) than for P (0·94) or C+ P (1·05), C/P and P/C being inter-mediate (1·15). The water-filled volume of the rumen was proportional to weight, except that C/P (alternated sheep finishing on pelleted grass) had low volumes. Reticulo-rumen fill was greater for C (7·28 kg) than for P (3·97) or C+ P (4·53), P/C (5·90) and C/P (4·34) being intermediate. There were no other significant differences in organs or contents.4. Gains in empty-body weight (g/day) were: C, 112; P, 181; C/P and P/C, 126; C + P, 195.

Two experiments were conducted to evaluate the effect of fermented whole crop cereal on palatability and performance in finishing pigs. In Exp. 1, a total of 20 finishing pigs ((Landrace ´ Yorkshier) Duroc) were allotted to 4 dietary treatments to check the palatability of the dietary feed. Diet treatments were included a basal diet; FW = basal diets + 1% fermented wheat without inoculum, FWI = basal diets + 1% fermented wheat with inoculum, FB = basal diets + 1% fermented barley without inoculum, FBI = basal diets + 1% fermented barley with inoculum. Throughout the experimental period, pigs fed FWI and FBI diets had significantly higher feed palatability compared with FW, FB diets. In Exp. 2, a total of 20 finishing pigs were allotted to 4 dietary treatments (1 pigs/pen, 5 pigs/treatment). Dietary treatments were same as Exp. 1. In nutrient digestibility, pigs fed FWI had higher dry matter digestibility. The number of Lactobacillus in feces was significantly higher in FWI treatments inoculated with feed microorganisms. Our results indicated that dietary supplementation with fermented wheat and barley with supplementing inoculant had a beneficial effect in finishing pigs.

This study evaluated diets including whole or peeled (legs removed) crickets (Teleogryllus testaceus) in terms of diet digestibility, growth and nitrogen retention, using pigs as an animal model. The experiment included three iso-nitrogenous diets (18.4% crude protein) including either whole cricket meal (WC), body cricket meal (legs removed, BC) or fish meal (control) as the main protein source. Castrated male piglets (n=21, 30-45 days) with initial body weight 13.0±0.3 kg were allocated to one of the dietary treatments (7 piglets/treatment) in a fixed block design. The piglets were kept in single bamboo/wooden stalls with slatted floors and were adapted to the feeds and the housing for 5 days before starting the 25-day experiment. The diets were offered ad libitum, but close to appetite (approximately 5% of body weight). Feed intake was recorded and piglets were weighed every 5 days. During days 20-25, total collection of faeces and urine was performed. Dry matter and nutrient intake were higher for piglets fed the WC and BC diets than for those fed the control diet. From day 10, piglets fed BC and WC were heavier than piglets fed the control diet, but there were no differences between WC and BC. Dry matter digestibility was highest for diet WC, and ash, crude fibre and crude fat digestibility was higher for BC and WC than for the control diet. Feed conversion ratio was lower for the WC and BC diets than for the control diet, and nitrogen retention (% of digested) was higher. We concluded that field cricket meal is a nutritious feedstuff for mono-gastric animals, and most likely also for humans. Removal of legs did not facilitate or improve the digestibility values and nitrogen retention. Thus, in order to minimise food waste, crickets should not be peeled in this way if they are going to be processed into meal.

Abstract The study was conducted to assess the effect of black pepper (BP) supplementation on the growth performance, nutrient digestibility, fecal microbial, fecal gas emission, and meat quality of finishing pigs. A total of 180 crossbred [(Landrace × Yorkshire) × Duroc] finishing pigs with average initial body weight (BW) of 53.72 ± 1.42 kg were used in 10-week trial and allotted to 6 dietary treatments (6 replications pens/treatment with 5 pigs per pen). The dietary treatments were: CON (basal diet), TRT1- CON + 0.025% BP, TRT2- CON + 0.05% BP, TRT3- CON + 0.1% BP, TRT4- CON + 0.2% BP, TRT5- CON + 0.4% BP. A linear increase (P = 0.0380, 0.0061) in body weight gain (BWG) and average daily gain (ADG) were observed respectively, during the overall trial in pigs fed BP supplemented diet compared to control. The dietary supplementation of BP showed a linear increase (P=0.0065) in gain and feed ratio (G: F) at week 10. However, there were no significant results observed on average daily feed intake (ADFI) during the overall experiment. The total tract digestibility of dry matter (DM) was linearly improved (P=0.0531) in BP treatment groups compared to control. In addition, BP diet supplementation had linearly increased fecal Lactobacillus counts (P=0.0482) and decreased E. coli counts (P=0.0306) in pigs at week 10. Furthermore, NH3, methyl mercaptans, and acetic acid was linearly decreased (P=0.0227, 0.0555,0.0541) in pigs fed BP supplementation compare to control. The inclusion of BP supplementation in pigs diet had linearly increased (P=0.0146) the backfat thickness at week 10. Thus, we concluded that BP supplementation had positively enhanced the growth performance, nutrient digestibility, fecal microbial, fecal gas emission, and meat quality of finishing pigs.

Three yearling Cheviot × Suffolk ewes and three Columbia wethers were confined in metabolic cages and fed ad libitum fresh and dried marrow-stem kale (Brassica oleracea var. acephala D.C.) harvested in mid- and late October. Chemical analyses of the forages indicated no marked effects on any of the plant constituents due to drying or advancing maturity. Digestibility measurements demonstrated that marrow-stem kale (MSK) was a highly digestible material with an average dry matter digestibility of 78%. The fresh forages had higher (P < 0.05) dry matter and gross energy digestibility values than the dried form. Dry matter digestibility coefficients were higher (P < 0.05) for late October as compared with the earlier harvest. A trend toward higher (P > 0.05) voluntary intake values due to drying maturity was observed with an average relative intake of 80%. The nutritive value index averaged 65, thus indicating a digestible energy intake similar to a high-quality (legume) forage.

The objective of the present experiment was to study the effects of the third-cut grass silage compared with the first- and second-cut silages on intake, performance and carcass characteristics of finishing bulls. A feeding experiment comprised 45 Simmental bulls which were fed a total mixed ration ad libitum. The three dietary treatments included either first-, second- or third-cut grass silage (550 g kg-1 dry matter), rolled barley (435 g kg-1 dry matter) and a mineral-vitamin mixture (15 g kg-1 dry matter). Dry matter and energy intakes and growth rates of the bulls increased when either first- or third-cut silages were used instead of the second-cut silage. This was probably due to differences in digestibility, which was the lowest in the second-cut silage. There were no differences in intake or growth between the first- and third-cut silage-based rations. No significant differences in carcass traits among the feeding treatments were observed.

<p>The development of sheep livestock is done as a comodity producer to meet the need of the meat. 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. Variansi analysis results show that the dry matter consumption, organic matter consumption, dry matter digestibility, and organic matter digestibility is not significantly different (P ≥ 0.05). Conclusion of this research is the use of worm flour (Lumbricus rubellus) in feed up to 6% of the total concentration does not affect consumption and digestibility of dry and organic matter, but able to maintain the quality of<br />local male sheep feed.</p>
