RB30-252 Sex and Age as Factors in Cattle Feeding

Varying economic conditions and changes in the demands of the meat consuming public have been responsible for the turns that have taken place in the beef industry during recent years. Both feeder and producer must recognize and conform to these changes if they are to continue in business. Among the most important of these changes have been the turn toward the marketing of lighter cattle and the gradual disappearance from feed lots of two- and three-year-old animals. Furthermore, the cattle population of the United States is fast reaching stabilization with the resulting effect that more heifers are being marketed, since only one-fourth of the heifer crop is needed to replace worn-out breeding animals. Realizing the increasing importance of the heifer problem from the standpoint of the producer, feeder, and consumer, the Nebraska Experiment Station undertook to compare steers and heifers in a series of trials both in the feedlot and in the beef. It was hoped that these experiments would yield results which would bring out existing differences, if any, between steers and heifers both in quality and quantity of beef produced and thus provide or disprove many of the complaints against heifers. The results of these trials are summarized in this bulletin. Age as well as the sex factor has been considered, since two-year-olds, yearlings, and calves were included in these trials.

Whole-genome linkage analysis of rheumatoid arthritis susceptibility loci in 252 affected sibling pairs in the United Kingdom

Objective. To undertake a systematic wholegenome screen to identify regions exhibiting genetic linkage to rheumatoid arthritis (RA). Methods. Two hundred fifty-two RA-affected sibling pairs from 182 UK families were genotyped using 365 highly informative microsatellite markers. Microsatellite genotyping was performed using fluorescent polymerase chain reaction primers and semiautomated DNA sequencing technology. Linkage analysis was undertaken using MAPMAKER/SIBS for single-point and multipoint analysis. Results. Significant linkage (maximum logarithm of odds score 4.7 [P = 0.000003] at marker D6S276, 1 cM from HLA-DRB1) was identified around the major histocompatibility complex (MHC) region on chromosome 6. Suggestive linkage (P < 7.4 × 10-4) was identified on chromosome 6q by single- and multipoint analysis. Ten other sites of nominal linkage (P < 0.05) were identified on chromosomes 3p, 4q, 7p, 2 regions of 10q, 2 regions of 14q, 16p, 21q, and Xq by single-point analysis and on 3 sites (1q, 14q, and 14q) by multipoint analysis. Conclusion. Linkage to the MHC region was confirmed. Eleven non-HLA regions demonstrated evidence of suggestive or nominal linkage, but none reached the genome-wide threshold for significant linkage (P = 2.2 × 10-5). Results of previous genome screens have suggested that 6 of these regions may be involved in RA susceptibility.

Diário da Constituinte [gravação de vídeo] : [programa n. 252]

Continua a votação do substitutivo na Comissão de Sistematização da Assembleia Nacional Constituinte (ANC). Aprovado o acesso dos cidadãos aos bancos de dados públicos. O Deputado José Genoíno (PT-SP) apresentou destaque para que também haja acesso aos órgãos de segurança. Aprovado o destaque apresentado pelo Deputado Nelson Jobim (PMDB-RS) que prevê que as informações públicas requeridas pelo cidadão serão prestadas no prazo da lei. Esse destaque foi extraído de uma emenda popular. Aprovado destaque do Deputado Jovanni Masini (PMDB-PR) que concede asilo político aos indivíduos que sofrem perseguição em razão de raça, de nacionalidade ou de convicção política. Aprovado também a parte do texto que dispõe sobre a extradição de brasileiro naturalizado envolvido comprovadamente com o tráfico de drogas. O Deputado Francisco Rossi (PTB-SP) declara que essa emenda fere fundo o tráfico internacional de drogas. Deve ser prorrogado o prazo para a conclusão da votação na Comissão de Sistematização. O Relator Bernardo Cabral (PMDB-AM) considera que o mais conveniente seria não estabelecer prazos, mas sim ver o desenvolvimento dos trabalhos. Afirmou também que a decisão sobre a prorrogação, de acordo com o regimento interno, é da Mesa da Assembleia Nacional Constituinte. Membros da União dos Jovens Socialistas (UJS) estão mantendo plantão em Brasília. Eles querem o serviço militar facultativo e o voto a partir dos dezesseis (16) anos. O Coordenador da UJS Apolinário Rebelo declara que 55% dos jovens entre 16 e 18 anos já trabalham e, por isso, devem ter também o direito de votar. A bancada jovem da Constituinte apoia a iniciativa. O Deputado Expedito Júnior (PMDB-RO) crê na aprovação da proposta na Comissão de Sistematização.

RB30-246 Testing Ice Cream for Butterfat

Butterfat is usually the most expensive ingredient of ice cream; hence, great care is necessary in controllng its use. The manufacturer of ice cream, whether doing a large or a small volume of business, must manufacture a product that will comply with the established fat standard. Some means of determining the percentage of butterfat in the product must be available in order to establish this control. This 1930 research bulletin discusses the different testing equipment used to test butterfat in ice cream.

RB30-250 Raising Early Lambs from Aged Western Ewes

Many farm flocks in Nebraska are comprised of aged western ewes. They are easily obtained because of the state's geographical position with reference to the sheep-producing sections of the West and the leading feeder lamb markets. Nebraska ranks second in number of western lambs fed. This also tends to acquaint farmers with range sheep. This 1930 research bulletin discusses factors in early lamb production; objects of the experiment, experimental procedure, and experimental data of raising early lambs from aged western ewes.

RB30-245 Water Supply and Sewage Disposal Systems for Farm Homes

When the well "goes dry" or when the windmill or pump breaks down, every one in the household immediately appreciates the value fo plenty of water. In other words, "You never miss the water until the well runs dry." Fortunately, in most sections of this state, plenty of pure water may be obtained by sinking wells of moderate depth, yet surprisingly few farm homes are supplied with running water in the kitchen even though the barn yards are equipped with hydrants and tanks. It is the purpose of this bulletin to present a number of water supply and sewage disposal systems which have been used in Nebraska and surrounding states and which add greatly to the comfort and convenience of the farm home.
