Mealworm Larvae

This study determined if yellow mealworm larvae (YML) grown on deoxynivalenol (DON) contaminated wheat would affect broiler chicken performance. The YML were reared on wheat with low (LDW; 630 μg/kg) or high (HDW; 30,730 μg/kg) DON concentrations. The DON concentrations in the dried insect meals were 0 or 17.5 μg/kg for YML grown on LDW and HDW, respectively. Seventy-five male Ross 708 broilers were randomly placed into 15 cages and reared on one of three diets from day 1-35 (five replications/treatment). On day 14, broiler numbers were reduced to four per cage. The diets consisted of a control containing no YML meal (CD) and two diets containing 5% YML meal produced on either LDW (LMD) or HDW (HMD). Feed intake and body weight (BW) were measured over the duration of the experiment to calculate feed to gain ratio (F:G). On day 35, all birds were slaughtered and dissected to collect weights of the breasts, thighs, drums, wings, abdominal fat pads, and organs. Crude protein retention was higher in birds fed the LMD and HMD treatments compared to CD (P=0.0091). Dry matter retention was higher in the HMD diet compared to the CD and LMD diets (P=0.0046). Feed intake was lower in birds fed HMD compared to CD and LMD (P=0.0031) although final BW was not reduced. In conclusion, dietary inclusion of YML did not affect the growth, meat yield or organ weights of the birds. The YML reared on DON-contaminated wheat (up to 30,730 ug/kg) and included in broiler diets at 5% could be an effective means of converting salvage wheat into a safe and sustainable source of protein.

In a laboratory study, the results of ensiling caged layer poultry waste with carbohydrate source to enhance its usefulness as feed ingredient for livestock were reported. Poultry waste (20%) mixed with cassava or sorghum flour was ensiled in test-tube silos and sampled at intervals during a 14-day storage period. In both mixtures, the dry matter (DM), crude protein (CP) and pH values were significantly. in Nigeria, poultry waste was affected (P<0.05) with time after ensiling. The DM values were higher (P<0.05) on day 10 than on day 0,5 or 14. The poultry waste-sorghum mixture increased in CP level (P<0.05) from 8.0% on day O to 9.1% on day 14 while in the  cassava mixture CP increased from 7.0% on day  7.6% on day 10. There was a drop in pH from 6.4 to 4.6 in both mixtures at the end of the storage period. The results showed that ensiling cassava or sorghum flour with poultry waste enriched the nitrogen content of the mixture thereby enhancing its usefulness  as livestock feed.

To evaluate the chemical composition of the earthworm (Eisenia foetida) co-dried (EW) with vegetable meals (VM) as animal feed ingredient, the blends were mixed with wheat bran (WB), rice powder (RP), corn meal (CM) and soy cake meal (SCM) in proportions of 85:15; 75:25 and 65:35. The dry matter (DM), crude protein (CP), crude fat (CFA), crude fiber (CF), ashes and nitrogen-free extract (NFE) of the ingredients and final mixtures were determined. All the mixtures resulted with a high content of DM (≥90.00 %). No significant differences among the proportions were revealed (P>0.05). In addition, the higher inclusion of the earthworm in the proportions (85:15) increased (P<0.05) the CP (54.70 %), CFA (7.28 %), and ashes (10.20 %), mainly when mixed with SCM, CM, and RP, respectively. However, the use of vegetable meals proportionally increased the CF (7.31 %), and NFE (52.62 %), mainly with the proportion of 65:35 and with RP and CM, respectively (P<0.05). The results showed that the vegetable meals (WB, RP, CM, and SCM) are useful to co-dry the earthworm to be use for animal feed. It is concluded that the most appropriate proportion (VM:EW) will depend on the animal species, productive stage and market requirement.

Nulliparous crossbred does were used to study the effects of concentrate:lablab ratio (CL) and stage of pregnancy on nutrient intake and digestibility. Treatments consisted of four concentrate and lablab combinations on a gram:gram basis: 20:130, 40: 110, 80:70 and 100:50 and two stages of pregnancy: second and fourth week of pregnancy Concentrate intake increased as level increased up to 80g/day offered while lablab intake increased from 50 to 130g/day offered. Doe weight and metabolic size were similar for all treatments. Total feed intake was not affected by concentrate and lablab levels. Dry matter intake was lower for 100:50 CL than other treatments. Ether extract and crude fibre intakes decreased with increase in concentrate levels. Dry matter and nitrogen free extract digestibility were higher for 80:70 CL than other combinations. Crude fibre digestibility was higher for 80:70 than 40:110 and 100:50 CL Crude protein retention was higher for 80:70 than 20:130 and 100:50 CL. Fetal growth requirement, total protein requirement and balance of protein were high at 80:70 and 100:50 CL. During pregnancy, dry matter and all nutrients intake were higher in the second than fourth week. Ether extract, crude protein and nitrogen free extract digestibilities were lower in the second than fourth week of pregnancy. Fetal growth requirement and balance of protein were higher in the second than fourth week of pregnancy relationship between feed intake (g DM/day) and nutrient digestibility was negative. The relationship between feed intake (g DM/kg body weight/day) and feed intake (g DM/kg LW0.75/day) was however, positive for all the nutrients except crude protein. For the small scale rabbit producer in developing countries, it is feasible to maintain rabbits on combinations of concentrate and lablab during pregnancy

The effect of two different composts: horse manure and broiler chicken manure and the influence of flushes during the growing cycle on some chemical components contained in the mushroom (<i>Agaricus bisporus</i>) was studied. The strain Somycel 11 was analyzed. The following determinations were made: dry matter, total nitrogen and crude protein, nitrates, nitrites and amino acids composition. It has been noted that the crude protein from. combined flushes III to VI of mushrooms cultivated on horse manure was about 24% higher than in those grown on broiler chicken manure. Some changes in amino acids composition, especially lysine, histidine, arginine, aspartic acid, serine, methionine, glutamic acid and alanine were observed, depending on the size of the fruit-body, flushes and type of compost.

This research has been done during August 2004 - January 2005 at Laboratorium Ilmu Ternak Potong dan Kerja, Fakultas Peternakan Universitas Diponegoro Semarang. The study was set up to investigate the performance of ongole crossbred and Friesian Holstein crossbred young bulls fed concentrate and Napier grass hay. This research used 4 yearling ongole crossbred (PO) bulls with the initial body weight: 228,17 + 14,77 kg (CV = 6,47%) and 4 yearling friesian holstein crossbred (PFH) bulls with the body weight: 196,34 + 7,64 kg (CV = 3,89%). The Independent Sample Comparisons was used in this study. Those bulls were fed 30% hay of Napier grass and 70% concentrate made of “bungkil kelapa sawit” (80%) and rice bran (20%). The ration was given based on dry matter need, 2.5% of the body weight. Parameters observed were the average daily gain (ADG), feed intake (dry matter intake, crude protein intake, Total Digestible Nutrients’ 2 Sains Peternakan Vol.8 (1), Maret 2010 intake) and feed conversion. Data were analyzed using t-test; except for feed conversion was analyzed deskriptifely.The result indicated that those cattle fed concentrate and Napier grass had ADG and feed intake relatively similar. The average of ADG PO bulls were 0.21 kg and PFH bulls were 0.22 kg. Dry matter intakes of PO and PFH bulls were 3.33 kg/day and 2.83 kg/day. Crude protein intake of PO bulls were 0,45 kg/day and that of PFH bulls were 0,38 kg/day, whereas TDN intake of PO bulls were 1,93 kg/day and PFH bulls were 1,20 kg/day. Feed conversion of PO bulls was 15.86 and that of PFH bulls was 12.86. It can be concluded that the performance of Ongole crossbred and Friesian Holstein crossbred young bulls fed concentrate and Napier grass hay was similar. Those indicated that PFH bulls had productivity that was the same as PO bulls. Key words : Bulls, performance, feed intake, feed conversion

Four Levels

The effects of level of feed intake and monensin on rumen fermentation and digestibility in steers were evaluated. The four levels of feed intake were 30, 50, 70 and 90 g of dry matter per kilogram body weight raised to the 0.75 power (g/kg0.75). Monensin was included at 0 and 33 mg/kg diet. The diet contained 60% rolled barley and 36.5% alfalfa pellets. Organic matter digestibility decreased (P < 0.05) with increasing levels of intake when the control diet was fed but was not affected by intake when monensin was included in the feed. Crude protein digestibility was consistently higher (P < 0.05) in monensin than control-fed steers at all four intake levels and decreased with increasing feed consumption in steers fed both control and monensin diets. Rumen fluid pH and ammonia and plasma urea nitrogen were not affected by monensin, and decreased (P < 0.05) as feed intake increased. Both higher feed intake and monensin caused an increase in the molar proportion of ruminal propionic acid and a decrease in the proportion of acetic acid.

Voluntary Intake

SUMMARYTwenty-seven sheep feeding trials were carried out on freshly cut Andropogon gayanus, fed daily during three wet seasons, 1966–8.In each year, dry-matter voluntary intake and digestibility were highest during the first part of the growing season and declined with advancing maturity of the herbage. However, at the time of ear emergence in early October, there were small increases in voluntary intake of dry-matter and crude protein digestibility, although further decreases followed after mid-October.Determinations of in vitro digestibility indicated that elongating stems during early October were at least as digestible as leaves.Seasonal changes in crude protein digestibility were much greater than changes in dry-matter digestibility; seasonal changes in feed intake were intermediate. Voluntary feed intake was related to dry-matter digestibility.Voluntary feed intake and digestible crude protein were both closely related to the crude protein content of the forage. It was concluded that crude protein is a useful criterion for predicting nutritive value.
