Rearing entire male pigs presents several benefits, including enhanced feed efficiency, reduced environmental impact, and improved animal welfare. However, the risk of boar taint poses a significant challenge to pork quality. The objective this pilot study is evaluate growth performance, meat quality incidence in intact Bísara breed (BI) terminal cross (TC). Five from each were monitored during blood samples taken measure tainting compounds (skatole androstenone). was compared concerning its...

Abstract. The objective of the current study was to adjust a growing curve suckling piglets as function hierarchical position achieved and mammary gland allocation (anterior, medium, or posterior) for investigation of, eventually, different patterns. For this purpose, 280 from 20 sows (14 per sow) were weighed observed birth weaning. weight in three groups found be significantly (P<0.05), with heavier gaining access more productive anterior teats. quadratic best fit model piglets' growth...

This study aimed to evaluate the microbiological quality of colostrum on three dairy farms with different management hygiene practices and compare it current guidelines. On farm A, was fed raw, while B C heat-treated. A feeding equipment were cleaned manually, an automated cleaning system used. Samples collected from calf submitted for microbial culture: total plate (TPC), coliforms (TCC), E. coli, enterococci, staphylococci (STAP), lactic acid bacteria counts; in addition, pH, aW, Brix...

Production of the autochthonous Portuguese sheep breed Bordaleira de Entre Douro e Minho (BEDM) is directly associated with concept sustainable agriculture. This focuses on adaptation animal populations to adverse environmental conditions, high biological efficiency and traditional management. Native BEDM can be divided into following two types basis their geographic location in Portugal how they are managed: Várzea, which found mainly lower region, Mountain type, traditionally prefers...

Body measurements in Portuguese Holstein-Friesian breed and its association with the dimensions of cubicles were investigated.During a period 5 months, body size data from 55 commercial dairy herds collected including total 1054 individual cows.Data analyzed using general linear model principal components.The most relevant were: height at withers (141.1±4.72 cm), rump (144.2±4.47 length trunk (170.8±8.31cm), width biiliac (55.9±4.17cm) perimeter thorax (206.8±10.43cm).In general, first class...

Las vacas lecheras son animales muy sensibles a los cambios ambientales y requieren alojamientos cada vez más sofisticados para prevenir la aparición de estrés térmico en épocas calurosas que eviten importantes pérdidas económicas por disminución producción. El objetivo del presente estudio consistió valoración explotación indicadores fisiológicos las su influencia sobre producción leche. Se monitorizaron temperatura humedad relativa aire intervalos una hora, través sondas digitales...

This research sought to determine the effect of selected milk protein polymorphisms on reproduction parameters 598 black and white Polish Holstein–Friesian cattle. The analyzed genes were kappa-casein (CSN3) beta-lactoglobulin (BLG). following reproductive indexes selected: age at first calving, interpregnancy period, calving interval, insemination index. influence identified genotypes course parturition in cows was also analyzed. Source data collected for each cow from beginning herd life...

This work focuses on the effect of slaughter age (6 and 9 months) sex carcass characteristics meat quality Minhota cattle breed. In this study, data from 52 (34 entire males 18 females) were used for characterisation. Regarding characteristics, male carcasses (158 kg 223 animals 6 months, respectively), heavier than female (130 161 with better dressing percentages, increased lengths, thicknesses depths compactness indexes. The both females had strong luminosity (L*), a pale pink tone (lower...

Precision Livestock Farming (PLF) can be seen as the application of state-of-the-art methodologies and technologies in favour optimizing animal production processes. Adopting PLF includes automatic, continuous nearly real-time monitoring production, welfare health condition, which results valuable information that used to support farmer decision-making improve performance. A major challenge livestock farming is related improvement cattle reproductive Reproductive inefficiency has a negative...

This study explored the demand for improved farm animal welfare (FAW) legislation in BRIC countries and USA. Results are discussed comparison to Europe. Interviewees ranked their willingness support or oppose introduction of more FAW-friendly laws country. A multinomial logistic regression was fit data (p < 0.001), with parameters "country × gender" 0.001) age" found significant. Americans, Russian women, older Brazilian men very supportive. The age effect is also felt India, where people...

Regularly weighing calves helps to assess the efficiency of rearing period and contributes animal welfare by allowing more precise feeding medication application in dairy farming, but many farmers do not weigh their regularly. Improving feasibility this process is, therefore, important. The use morphometric measurements has been used estimate weight cattle. However, studies have focused on adult animals or a wide age range. As experience allometric tissue growth, specific models for certain...

Hoof trimming and shoeing determine the horse's hoof shape balance. conformation plays a crucial role in limb biomechanics can consequently prevent or predispose to injury. This study investigated relationship between morphometric characteristics of hoof, specifically, dorsal wall angle (DHWA), coronet band circumference (CBC), lameness 73 horses categorised as undertaking either show jumping, dressage, riding school activities. Results from logistic regression indicated that with...

The veal niche market is gaining momentum in Brazil. Locally known as ‘Vitelão’, refers to the meat from calves slaughtered up 12 months of age. In this study, we assessed Galician Blond × Nelore cross a candidate produce veal. aim study was establish criteria for selecting 12-month-old suitable slaughter. To find best fit, adjusted various growth models Once fit determined, selected model then used calculate relative and instantaneous rates evaluate slaughtering potential at months. Our...

The production of rabbit`s meat using the flat deck cage systems, should consider a minimum space per animal. stocking density be assessed considering effect on animal welfare and productive capacities. objective this work was to study growth rabbits through fattening submitted different densities. In commercial farm 300 were distributed in 40 cages with floor area 3600 cm2/cage, subjected following densities: 6 (6C) 9 (9C) rabbits/cage. animals weighed at weaning, 37 days old (d), 64 d 71...

La utilización de razas locales en sistemas producción alternativos presenta una serie ventajas, como la gestión medioambiental, biodiversidad y agrícola sostenible orientada hacia un mercado productos calidad diferenciada, especialmente áreas desfavorecidas. En este trabajo se estudió influencia dos canal cerdos raza Bísara. alimentación recibida fue igual ambos casos. fase crecimiento (98 días) alimentaron con pienso compuesto comercial, mientras que durante el acabado les administró...

A growing interest has been shown in outdoor swine production systems due to the lower initial investment cost (facilities, buildings and equipment's). Simultaneously, concerns with animal welfare awareness of niche marketing opportunities have increased free-range animals. The Bísaro pig northern region Portugal mainly adopted traditional system rather than alternative systems. Facilities accommodation factors influence both environment growth performance, making this issue a key point for...
