Row Width

Midas marrowstem kale (Brassica oleracea L.) was grown in different row width associations with United 106 corn (Zea maize L.) in two studies and ensiled in different moisture blends with corn stover in another. Highest dry matter yields were obtained where a single row of kale was grown at 30 cm to the side of a corn row. This combination also provided the lowest moisture content feed and the highest in vitro digestibility and crude protein content. Changing the corn row width had no significant effect upon yield, plant height, in vitro digestibility, kale leaf or corn ear content. Blending kale with corn stover to provide a silage of about 70% moisture increased the digestibility and protein content of the feed and provided a silage that kept well in storage.

ABSTRACT The aim of this study was to identify parents and promising hybrid combinations for the improvement of forage watermelon. Five parents were evaluated: BGCIA 996 (1), BGCIA 997 (2), BGCIA 998 (3), BGCIA 228 (4), Jojoba (5) and ten F1 hybrids, which were obtained from balanced diallel crosses. The experimental design was in a complete randomized block, with three replications. The morphoagronomic and bromatological traits were evaluated. The highlights were the progenitors BGCIA 997, BGCIA 998, BGCIA 228 and Jojoba for protein content, fruit yield, in vitro digestibility of dry matter and number of seeds, respectively. The hybrid 1x4 stood out for fruit length, seed number, and ethereal extract. The hybrid 2x3 stood out for rind and pulp thickness while the hybrids 3x4, 3x5 and 4x5 had exceptional digestibility, protein content and fruit yield, respectively. The analysis of the standard deviation of the SCA estimates of both SD (Sij- Sik) and SD (Sij- Skl) indicated that no hybrids were found that had SCA estimates twice that of SD (Sij- Sik) or SD (Sij- Skl), except for the hybrid 1x4 for the number of seeds per fruit. These results suggest that the parents were more promising than the hybrids. Similarly, the GCA estimates favor the intrapopulation method, which will promote greater efficiency in selection for genetic gains.

Alfalfa dry matter production, plant height, protein content, and in vitro digestibility (IVD) were measured in first- and second-year plantings of six alfalfa cultivars grown under natural potato leafhopper infestation with and without methoxychlor treatment for control of the pests. All treated plots yielded more dry matter than the untreated check, except Angus in 1978. Plant height and protein content were higher and IVD was less in the treated plots. All cultivars were susceptible to leafhopper infestation; however, Angus was the least affected. Leafhopper injury was season-specific and damage carry-over from one season to another occurred but was less than from one cut to the next.

Fluazifop-P, applied in the spring or fall and pronamide, applied in the fall only, reduced quackgrass infestation in established alfalfa and increased the dry matter yield of alfalfa. Herbicides did not improve alfalfa in vitro digestibility or crude protein content. Average residues of fluazifop-P in alfalfa treated with rates of 0.25 or 0.5 kg ai ha–1, were 0.1 mg kg–1when harvested 280 d after application, and 0.06 mg kg–1when harvested 295 d after application. Average residues in alfalfa harvested 41 and 55 d after application were 0.13 mg kg–1and 0.1 mg kg–1, respectively, with a 0.25 kg ha–1treatment and 0.19 mg kg–1and 0.05 mg kg–1, respectively, with a 0.5 kg ha–1treatment.

Rate Of Decline

The in vitro dry matter digestibility (I.V.D.) of the immature stems of timothy, orchardgrass, and bromegrass was higher than that of the leaves. However the rate of decline of digestibility with advancing maturity was greater with stems. At head emergence the I.V.D. of the leaves of orchardgrass was similar to that of the stems. Wide differences existed, though, in the I.V.D. of leaf and stem fractions of orchardgrass at more advanced stages of growth. Digestibilities of the plant parts of both timothy and bromegrass were not greatly different at any growth stage.The digestibility of leaves of alfalfa decreased only slightly as the season progressed. However, the I.V.D. of the stems declined rapidly early in the season. Unlike the grasses, the stems of alfalfa never attained as high a digestibility as the leaves at the early growth stages.The crude protein content of both leaf and stem portions of the various grass species was similar.As the season progressed, orchardgrass had the highest leaf to stem ratio and bromegrass the lowest. Even within a species, leaf content was a rather poor indicator of digestibility.

Extruded Snacks

The demand for healthy, satiating, and convenient products is growing, with ready-to-eat expanded snacks being the preferred. These are produced made by extrusion, which is a versatile and efficient technology, with an immense potential to develop new food products. In addition to satisfy consumer requests, it is interesting to add alternative protein sources to these products, such as insects that have nutritional benefits and ecological advantages. The aim of this work is to evaluate the effect of extrusion temperature and enrichment with house cricket (Acheta domesticus) on properties of extruded snacks. Extrudates were produced with a single-screw extruder at two barrel temperatures (165 and 175 °C), formulated with corn flour and house cricket powder in mass ratios, 100:0, 95:5, 90:10, and 85:15. Water content, water activity, expansion, porosity, water absorption, water solubility indices; swelling index and hygroscopicity; colour, texture, protein content, in vitro digestibility, and protein bioaccessibility were measured. The results suggest that incorporating edible insects in extruded snacks can be a good alternative to the snacks on the market, since they maintain the appropriate physicochemical characteristics, especially when formulated at low temperatures. Further, they improve the protein content, with the recommended percentage use of 5 and 10% of house cricket, for the formulation of snacks with extrusion at 165 °C.

Yield And Quality

At Kyabram, Victoria, the effects of growth stage at cutting on dry matter (DM) yield and quality of lucerne was determined during the warm season haymaking period for cultivars with contrasting winter dormancy characteristics. Growth stages at cutting were pre-flower bud, flower-bud, 10% bloom and full bloom. Cultivars were winter non-dormant CUF 101 and Pioneer Brand 572, semi-winter dormant Pioneer Brand 581 and winter dormant Pioneer Brand 545. Cultivar responses or interactions between cultivar and growth stage at cutting were not significant (P>0.05) for dry matter yield, crude protein or in vitro digestibility. Cutting of the pre-flower bud stage, compared with cutting at the 10% bloom stage, reduced DM yield by 18% (16.4 v. 13.5 t/ha), but increased crude protein content of the lucerne from 19.3 to 24%. The total protein yield per hectare was not affected by cutting stages from pre-flower bud stage to 10% bloom. Cutting lucerne at the flower bud stage rather than at 10% bloom gave increased protein content and digestibility with only a moderate yield decline. However, more frequent cutting was unsatisfactory as it decreased the density of the stand and increased the proportion of weeds and so could not be recommended.
