The mean weaned piglets of the Norwegian breed for each litter is 9 to 8, two to three times a year. These are capable of attaining a body weight of 220lbs (100kg) within 142 days after their birth. The average weight of the male Norwegian at slaughter is 350-375lbs (160-170kg).

For , Hulsegge et al. [62] reported that merging of commercial lines has reduced the genetic diversity of the population in the Netherlands, although a large proportion of …

Thus, the Norwegian may have great potential for a high FE when fed high-quality diets, but this may not be applicable when fed diets with higher fiber content and ANF. Genetic variability of organic matter (OM), N and energy digestibility in Large White fed a high-fiber diet has been reported ( Noblet et al., 2013 ).

Hermitage Purebred GGP and GP Females. IRELAND – Secure your herd health status and increase overall sow productivity by purchasing purebred Hyperprolific GGP or GP gilts straight from the Hermitage Freneystown nucleus. 3 December 2014. 2 minute read. By: Jackie Linden.

The aim of the study was to determine some offal components obtained from Pulawska and Polish fattening , and to analyse the eating quality of the offal products. The study material consisted of 100 fattening : Pulawska (PUL) and 50 Polish (PL) . The offal components were analysed for physical traits, chemical composition …

This study utilised a dataset including 340 of the Duroc, , and Yorkshire breeds. In the present paper, we propose a comparative analysis of various machine learning methods using outlier detection, normalisation, hyperparameter optimisation, and stack generalisation to increase the accuracy of the predictions of the live weight of …

In Norwegian population, results from simulation showed 13% or more gain can be archived for both production and maternal traits (Lillehammer et al. 2013). In Danish Duroc , the gain in reliability is 18–39% by using deregressed estimated breeding values as the response variable in GS (Ostersen et al. 2011).

Pietrain and Belgian show a similar degree of muscular hypertrophy and are markedly better than French in carcase muscle content (+5 percentage points). However, as the Pietrain and the Belgian greatly differ in terms of lean tissue growth rate, the responses of from these two breeds to the nutritional …

This study compared the growth, carcass properties, fatty acid profile, lipid-producing enzyme activity, and expression pattern of genes involved in fat metabolism in Nanyang and . In the study, 32 Nanyang (22.16 ± 0.59 kg) and 32 barrows (21.37 ± 0.57 kg) were selected and divided into two groups, each with eight pens and four per pen. The trial period lasted 90 …

The British breed, which was already in the RBST Watchlist’s most urgent ‘priority’ category, has seen a dramatic decline with just 23 dams producing pedigree progeny in 2022 …

2. . The origin of this breed is Danish and it’s characterized by its good feed conversion rate. This means that every takes advantage of the nutrients it consumes to grow healthy and strong. The body of these is white and quite elongated, so they have more ribs than other breeds. 3. Piétrain.

The average plasma GH concentrations among Tao-Yuan, and Duroc was 2 41 t 1.23, 3.85 t 1 25 and 4.20 t 1 02 ng/mL, respectively (Figure 2) The data showed that the plasma pGH concentration of the Tao-Yuan was only about one half that of and Duroc and this difference was statistically significant (P< 0 05 ...

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 …

Breed Features. There are different types of breeds for commercial and the breeds happen to be one of them….

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.

21.feb.2022 – Danish is a breed originally from Denmark. The Danish breed, known as , already existed towards the end of the 17th

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.

The Berkshire, Hampshire, Chester White and breeds produced the more tender pork chops among the eight breeds. The breed produced loin chops that were not juicy, even though they were above average for tenderness. The Duroc breed was intermediate for both tenderness and juiciness. Table 4.

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.

The average NBA and NW values were 12.7 and 12.1 in Yorkshire and 12.9 and 12.0 in , respectively. These results indicate a mean pre-weaning mortality of 4.9% in the Yorkshire herd and 7.5% in the herd. The LW21 values were 65.6 kg in Yorkshire and 66.8 kg in .
