Breeds. Four types of livestock and poultry breeds occur in North America: landraces, standardized breeds, industrial stocks, and feral breeds. These differ according to their history and selection, the relative level of uniformity versus variability, and the presence or absence of a formal structure to organize and promote them.

Here we used two kinds of chips data from 5 breeds, Chinese Duroc (DD), (LL), Yorkshire (YY), Liangshan (LS), and Qingyu (QY) in China to identify genes which show evidence of selection during domestication. Four breed pairs, LS-YY, QY-YY, DD-YY, and LL-YY pair, were performed to detect selection signatures using the Fst …

the organic cultivation of grains makes it possible to express the terroir of a crop. our historical grains are grown in diverse locations from the mountains to the sea. we also plant field blends of up to 10 varieties in one field, allowing nature to take its course and for a new varietals to be created

Duroc × ( × Yorkshire) are popular in the Chinese market because of their rapid growth, leanness, and economic value. Despite their widespread use in dry-cured ham processing, there is a lack of research on the bioactive peptides of Duroc × ( × Yorkshire) ham (DLYH).

A total of 72 finishing (; initial age of 150 d) were randomly divided into 3 treatments with 8 replicates of 3 each, and fed a basal diet or diet containing 500 mg/kg of RA or UA. The results showed that dietary supplementation of RA or UA had no significant effect on the growth performance and carcass traits of finishing …

Data from 3776 Large White and 2274 sows which farrowed between 1991 and March 1995 were used to obtain genetic parameters for reproductive traits of the sow recorded in the first, second and third parity. The pedigree data set of these sows included 150 Large White and 102 sires as well as 1284 Large White and 715 dams.

In sows, the risk ratio was much higher for sows with a litter size below that of the ‘s average, but for the other classes no clear tendency was observed. For Large White sows, the risk ratios were similar for farrowings 2 to 4 in both Weibull and grouped data models and from parity 6 (not shown) it increased.

For Canadian farmers, feeding this breed can be a little tricky but worthwhile. For optimal health and growth, the Danish Goose should be fed a balanced diet with a protein content of 18% minimum. This can be achieved through a combination of grains and commercially produced diets, with provisions for pasture grazing when possible.

The Swedish is a breed that needs attention from farmers regarding their diet. This breed can feed outdoors, however, this diet has to be supplemented. Swedish breeders have also tried to maintain a satisfactory rate of gain and feed conversion. In order for this breed to grow rapidly, it needs to eat around 3 to 3.5 kg per day.

About 15% of CpG islands were methylated in the genomes. Additionally, 2,807, 2,969 and 5,547 differentially methylated genes (DMGs) were identified in the Tongcheng vs. , Tongcheng vs …

Six pure wild boar (S. scrofa L.) and six domestic ( × Large White) with liveweights (mean ± S.E.M.) of 26 ± 0.6 and 21 ± 1.1 kg were obtained from commercial farms. The of origin of the wild boar does not have a genetic selection programme.

The animals were obtained from a swine breeding program located in Santa Catarina, Brazil. This line was initially developed from the crosses of eastern and western breeds and the expected proportion of the genes were 50% , 12.50% Meishan, 12.50% Xia Jing, 8.33% Hampshire, 8.33% Pietrain and 8.33% Large White.

In the Task Force on Conservation and Management report, Del Greco et al. (2007) chose to use the Villa et al.

Small effective population size of the Kolbroek might be due to being raised in a research facility with limited boars and sows. Large White, Duroc and South African are commercial that have undergone strong selection for meat and carcass traits thus resulting in small effective population sizes.

Sows derived by criss-crossing between the Large White and breeds produced 183 litters; from these, 1158 were group fed in pens averaging 16 of the same sire breed, from weaning to a mean liveweight of 80 kg, and slaughtered at 2 commercial plants.

Defining landraces. There are several definitions of the term (Zeven 1998; Villa et al. 2005; Negri et al. 2009; Casañas et al. 2017).According to FAO (), landraces are often “genetically and phenotypically heterogeneous, adapted to the environmental conditions of their cultivation areas, suited to the production systems and local culinary preferences and are generally associated …
