1. Characteristics of the wool produced by ewes raised for meat production
The objective of this study was to evaluate the characteristics of wool produced by ewes of different genetic groups, ages, and reproductive statuses. A total of 115 ewes, of the following genetic groups, were used: 10 Corriedale, 37 Hampshire Down, 26 1/2 Hampshire Down + 1/2 Corriedale, 24 1/2 Ile de France + 1/2 Corriedale, and 18 1/2 Suffolk + 1/2 Corrie

2. Influence of environmental factors on ponderal performance and morphometric characteristics of lambs of different genetic groups from birth to weaning
The objectives of this work were to evaluate the environmental effects (age of dam, type of birth and sex of lamb) and genetic groups (Hampshire Down and Ile de France, ½ and ¾ Hampshire Down, Ile de France and Suffolk, and ½ Texel) on performance and morphometric characteristics (height, length and heart girth) of lambs; to test regressions to predict li

3. Ovarian response of Suffolk ewes to estrous synchronization using short-term protocol
The efficacy of estrus synchronization using short-term protocol was evaluated by ultrasound exams in Suffolk ewes during the pre-breeding season. The control Group (n = 12) was synchronized by treatment for 12 days with vaginal sponges impregnated with medroxyprogesterone acetate, and 400 IU eCG at sponge withdrawal. Experimental groups I, II and III kept t

4. Produção de leite de ovelhas da raça Santa Inês e mestiças F1 e desempenho de suas progênies resultantes do cruzamento com carneiros da raça Dorper / Milk yield of Santa Inês and crossbred ewes and performance of their progeny after mating with Dorper rams
Dois experimentos foram realizados para avaliar o desempenho de ovelhas Santa Inês e mestiças F1 com machos de raças de corte e de suas crias obtidas do cruzamento com carneiros da raça Dorper. No experimento 1, setenta e cinco borregas ( 15 da raça Santa Inês (SI), 15 ½Dorper + ½SI, 15 ½Ile de France + ½SI, 15 ½Suffolk + ½SI e 15 ½Texel + ½SI

5. Eficiência reprodutiva de borregas de um rebanho suffolk no Rio Grande do Sul / Reproductive efficiency of yealing suffolk ewes in the state of Rio Grande do Sul - Brazil
O presente estudo teve como objetivo avaliar a eficiência reprodutiva de borregas Suffolk criadas na região do planalto médio do Rio Grande do Sul e submetidas ao encarneiramento na primeira estação reprodutiva. O Artigo 1 avalia o retrospecto reprodutivo das fêmeas desta categoria, com base em um banco de dados coletado do rebanho. Verificou-se que ov

6. Effects of nutrition on reproductive cyclic activity and on plasmatic melatonin concentration for ewes in pasture and submitted to the male effect, during seasonal anoestrus. / Efeitos da nutrição na atividade cíclica reprodutiva e nas concentrações plasmáticas de melatonina em ovelhas mantidas em pastagem e submetidas ao efeito macho durante o anestro sazonal.
O presente trabalho teve como objetivo avaliar os efeitos de diferentes condições nutricionais (suplementação e não suplementação) na atividade cíclica reprodutiva (ACR) em ovelhas das raças Santa Inês (SI), Romney Marsh (RM) e Suffolk (SU) mantidas sob pastejo, e submetidas ao efeito macho, durante época de anestro sazonal sob fotoperíodo natura

7. Pregnancy status and fetal prion genetics determine PrPSc accumulation in placentomes of scrapie-infected sheep
Ovine scrapie is a fatal neurodegenerative disorder that may be transmitted through exposure to infected uterine and placental tissues. Susceptibility to scrapie is primarily controlled by polymorphisms in the prion protein (PrP) gene. Scrapie in the U.S. Suffolk breed and in many breeds in Europe occurs in sheep homozygous for glutamine (171QQ), but rarely

8. Spontaneous mesangiocapillary glomerulonephritis in Finn cross lambs from Alberta.
A spontaneous mesangiocapillary glomerulonephritis occurred in three, one to three month old Finnish Landrace cross lambs from a flock in northern Alberta. The ram was a purebred Finn sheep, and the ewes were Finn-Rambouillet and Finn-Suffolk-Rambouillet crosses. The lambs were found dead without previous clinical signs. Histologically there was marked thick
