Abstract:

ABSTRACT: The objective of this study was to evaluate the effect of the racial crossing on scrotum-testicular biometric characteristics of four sheep Santa Ines and four crossbred (Santa Ines x Dorper) submitted to scrotal insulation, following the return of these characteristics to values previously reported. For this, two measurements were made regarding the scrotal circumference (SC), length (L) and testicular width (W) before treatments. The testicular volume (V) was calculated by the formula V=2 [(r2) x π x H]. The pouches were made with double-layer plastic, internally lined with cotton,

Abstract:

Scrotal circumference measurements were taken on 255 Salers bulls located at five growth performance test stations at the 56-d (26.9 ± 0.2 cm), 84-d (28.8 ± 0.2 cm) and 140-d weighings (30.8 ± 0.2 cm) in 1986, and on 248 Salers bulls located at four test stations at the 140-d weighing (31.3 ± 0.1 cm) in 1987. The estimated scrotal circumference measurement for Salers bulls at 365 d of age was 29.4 cm. Test station, percentage of Salers breeding within test station, sire of bull within year and test station, and the covariate body weight all contributed to the variance in scrotal circumference

Abstract:

Three methods were used by three technicians to measure the scrotal circumference (SC) of three breeds of yearling beef bulls. Variance of an individual SC measurement was affected most by bull. Technician and measurement error components were much smaller. The Society for Theriogenology method of obtaining SC measurements was recommended for use in Canada.

Summary Scrotal circumference was measured on all young Holstein bulls entering an artificial insemination center over a 57-month period. A total of 3,008 measurements were taken on 723 bulls between the ages of 5 and 18 months. Mean scrotal circumference, standard deviation, and 10th and 25th percentile statistics were calculated for each one-month interval between 5 and 18 months of age. Scrotal circumference increased as a logarithmic junction of age and was best described by a quadratic regression equation.

Seasonal variation of the reproductive activity of small ruminants in the southern USA is controlled by photoperiod. We tested the hypothesis that artificial manipulation of photoperiod has an effect on caprine testicular activity and semen quality. The objective of this study was thus to determine the effects of photoperiod on caprine scrotal circumference and semen parameters during the nonbreeding season.

Over an 8-yr interval, (1975–1982) scrotal circumference (SC) was measured on 4557 1-yr-old beef bulls from 1796 sires and eight breeds. Measurements were taken upon completion of a 140-d growth performance test. During the period 1977–1983, SC was measured on 7835 2-yr-old beef bulls from 2570 sires and six breeds. Two-year-old bulls were measured during reproductive examinations at spring bull sales. All SC measurements were adjusted for fixed effects of location-year and age, and heritability estimates were calculated within-breed using a paternal half-sib analysis. Heritability estimates f

Abstract:

Bapedi is a fat-tailed, hardy, and disease-tolerant breed of sheep that is indigenous to South Africa. The Bapedi sheep breed is facing genetic degradation due to nonselective cross-breeding and irregular mating; therefore, breeding strategies for urgent conservation of Bapedi sheep are crucial. The aim of the present study was to investigate the relationship between body measurements and semen traits of Bapedi rams conserved in situ (conserved in their natural habitat) and ex situ invivo (live animals conserved outside their natural habitat).

Abstract:

Zulu sheep is an adapted breed of South Africa with desirable traits such as their ability to thrive in a harsh environment and tolerant to various diseases. However, they are endangered, with their population size not exceeding 1000, and hence are associated with high inbreeding rates. Therefore, to limit biodiversity loss, there is a need to characterise and conserve its genetic materials. The aim of the study was to evaluate the relationship between morphometric characteristics and semen parameters of Zulu rams and conserve these genetics.
