This study characterises farmer’s preferences for breeding rams and tackles their willingness to contribute to the wool sheep Koundoum conservation programme through their quantified appreciation of the main phenotypic features of the sheep breed in the region. In Tillabéri region, i.e. the Koundoum sheep’s area of origin, the proportional piling tool is first used in 11 focus group discussions of breeders to determine the main selection criteria of breeding rams. The multi-attribute analysis me
The complex balance between innovation and conservation regarding animal genetic resources makes it difficult to find mutually accepted improvement pathways between breeders, government agencies, and research and education institutions. This study maps stakeholder viewpoints on cattle genetic improvement in Niger using the Q method, which appears effective in identifying the concerns of stakeholders on complex agricultural innovation topics.
The present study aimed at characterizing genetic diversity and relationship of 3 Niger cattle breeds (Zebu Arabe, Zebu Bororo and Kuri). High levels of allelic and gene diversity were observed while genetic differentiation was low. High genetic diversity and poor genetic structure might be due to historic zebu–taurine admixture and ongoing breeding practices in the region. The result of this study will help formulate effective strategies for conservation and improvement of Niger cattle breeds.
The long-horned Fulani zebu, spread all over the Sahel area, is one of the main cattle groups in Africa. Despite their importance, characterisation of these cattle is poorly developed. The current research illustrated a lack of differentiation among local populations of this cattle group at the body measurements level. Conservation or selection initiatives could be implemented at a cross-boundary level.
The effects of slaughter age and muscle type on meat quality properties of Eastern Anatolian Red (EAR) bulls (n = 46) were investigated in the present study. Forty-six EAR bulls were slaughtered at 15, 17, 19, 25, and 27 months. Meat samples were taken from longissimus dorsi (LD) and gluteus medius (GM) muscles obtained from the carcasses 24 h post-mortem.
The meta-analysis demonstrated that the relationships of major milk protein genes with other factors should be examined using the codominant genetic model in general. According to results of the meta-analysis, relationships among some CSN3 genotypes and fat yield, fat content, and protein content, and relationships among some BLG genotypes and daily milk yield, fat content, protein yield, and protein content were found statistically significant (p < 0.05).
Bovine cumulus–oocyte complexes were cultured in a three-step system imitating estradiol-17β (E2) and progesterone (P4) concentrations in preovulatory follicular fluid for in vitro maturation (IVM). The blastocyst formation rate after E2- and P4-imitated IVM was significantly higher than that after the other IVM (control, E2-imitated, P4-imitated), suggesting that the three-step IVM system with the preovulatory levels of E2 and P4 improves the developmental potential of embryos in vitro.
Intramammary infections in dairy cows lead to considerable economic losses for farmers. A new somatic cell count index (SCCI) was proposed for the accurate prediction of milk yield losses caused by elevated somatic cell count (SCC). Depending on the time of SCC elevation, parity, milk production level, and level of average SCC, the estimated milk yield loss from the phenotypic potential of milk yield was at least 0.8–0.9 kg day−1 for primiparous cows and 1.3–4.3 kg day−1 for multiparous cows.
This study aimed to determine the effect of cow breed, season and type of diet on the fatty acid profile of raw milk. The study was conducted on bulk milk samples collected in winter and summer from 4 herds of Czech Fleckvieh and 4 herds of Holstein cows. One half of the herds was grazed while the other half was not. Effect of breed was found in odd-chain, branch-chain and hypercholesterolemic FA while season and type of diet mainly influenced the proportion of saturated and polyunsaturated FA.
The aim of the study was to determine the impacts of different levels of mycotoxin load of dairy herds on the milk indicators. During three subsequent years, samples of feedstuffs and individual milk were collected from four herds of Czech Fleckvieh and from four herds of Holstein cows. The most frequently occurring mycotoxins were fumonisins, deoxynivalenol, and zearalenone. Changes were noted in some milk indicators such as fat, acetone, pH, electric conductivity, alcohol stability, or curd quality.
Our studies evaluated the effects of parity and season on pregnancy rates of repeat-breeder (RB) Japanese black beef cattle after embryo transfer. Our findings indicate that the parity of the recipients does not have an apparent effect on the pregnancy rates following the transfer of fresh and frozen embryos. However, season may affect reproductive performance in RB multiparous cows.
