    Notes: . A State loan program was analyzed for its effects on groundwater development in Wyoming. The analysis focused on the effects of low-interest State financing on the economic feasibility of investments in center-pivot sprinkler irrigation systems. The feasibility analysis indicated that investments in sprinkler systems for production of cash crops are highly profitable, and would frequently be carried out whether or not the State loan program were available. Investments in sprinklers for production of forage crops are perhaps frequently made attractive by the loan program. Thus, while the program appears to have accelerated the pace of private water resource development in Wyoming, it has also subsidized some investments that would have been carried out regardless of the program's existence. Further analysis indicated that sprinkler investments carried out with State financing contribute substantially to firm growth when cast crops are grown, but have less marked, and sometimes negative, effects on growth when forage crops are produced. Some positive effects of the loan program on southeast Wyoming's regional economy were noted, though a complete empirical analysis of regional impacts was beyond the scope of the study.

    Description / Table of Contents: Summary The influence of variing ratios of collagen to meat protein on bodyweight and carcass collagen of growing male rats was investigated. 1. Addition of sinew protein up to 5 % (28 % of total protein) to a feed mixture containing 13 % muscle protein yielded slight improvements on daily gain and feed conversion. In a ration containing 18 % muscle protein, 2 % grain protein and 2 % protein from fishsolubles and dried whey, the addition of 10 % sinew protein (31 % of total protein) depressed gain and feed conversion. 2. Raw sinew protein was utilized as good as cooked sinew protein. Autoclaving and drying meat and sinews together did not influence the protein quality of the mixture. 3. Analysis of total carcasses of 100 rats showed no influence of high collagen intake on collagen content.
    Notes: Zusammenfassung In drei Fütterungsversuchen wurde der Einfluß von Kollagenzulagen zu schierem Fleisch auf Entwicklung und Bindegewebsansatz wachsender männlicher Albinoratten untersucht. 1. Durch Zulagen von Sehnenprotein bis zu 5 % (28 % am Gesamtprotein) zu einem Futter mit 13 % Muskelprotein wurden die Gewichtszunahmen und die Futterverwertung noch etwas verbessert. Zulagen von Sehnenprotein in Höhe von 10 % (31 % des Gesamtproteins) zu einem Futter mit 18 % Muskelprotein, ca. 2 % Getreideprotein und ca. 2 % Protein aus Fishsolubles und Molkenpulver bewirkten bereits eine Depression der Gewichtsentwicklung und der Futterverwertung. 2. Zerkleinerte rohe Sehnen wurden von den Ratten ebenso gut verwertet wie gekochte Sehnen. Das Erhitzen der zerkleinerten Sehnen in Mischung mit zerkleinertem schierem Muskelfleisch beeinträchtigte die Proteinqualität der Mischung nicht. Die Ratten entwickelten sich mit diesem Futter ebenso gut wie mit Rationen aus einer nachträglichen Mischung aus getrocknetem Fleisch und getrockneten Sehnen. 3. Ganzkörperanalysen von insgesamt 100 Ratten ließen keine Beeinflussung des Bindegewebsansatzes durch hohe Kollagenfütterung erkennen. Im Mittel aller Untersuchungen (als Kriterium diente der Oxyprolin- und Glycingehalt) enthielten 40 Ratten, die ohne Sehnenzulagen gefüttert wurden, 20,8 % Bindegewebseiweiß im Gesamtkörperprotein. 60 Ratten mit 24–31 % kollagenem Eiweiß im Protein der Gesamtration enthielten 20,5 % Bindegewebe im Protein des Gesamtkörpers.
