(daily liveweight gain). In a combined analysis containing all parity groups, sows with the AC genotype had greater total number of born (1.80; P < 0.05) and number of born alive (1.82; P < … Hie Munya. Large White. Age at Maturity to Mate males and females. However, Duroc crosses (with up to 60% Duroc) crossed with white breeds have been shown to perform quite well as breeding females. [email protected], I have camborough sows and wish to met them with a white large boar. However, review full breed profile of the Large White pig in the chart below.

The breed is easily distinguished by it’s large size, picturesque bearing, erect ears and dished face. We are having a piggery project at school. Author information: (1)Graduate School of Agricultural Science, Tohoku University, Sendai, Miyagi, Japan. The Berkshire is a compact, short legged breed with a dished face, medium length snout and prick ears. to be evaluated and to target an individual optimum. These genetic trends are the average genetic trend of all participating herds. And it is named for it’s size. Learn more about Large White hogs, such as their history, characteristics, qualities, potentials and other vital facts. A medium sized breed, sows weigh around 220kg and boars 280kg. Although earlier history of the breed in Yorkshire is difficult to trace. Where can I get large white pure breed pigs in Ogunbode state. And average live body weight of the mature sows usually vary from 260-300 kg. Landrace: white, large drooping ears, long body, good mothers. Increasing litter size has long been a goal of pig breeders and producers, and may have implications for pig (Sus scrofa domesticus) welfare.

What are the disadvantages if this type of breed? In a Large White pig population, this polymorphism was associated with the number of piglets. High prolificacy, average litter size of 11 with a good weaning rate. The Large White can be used in a crossbreeding program in a variety of ways: However pedigree lines must be maintained in order to achieve the hybrid vigor. In Large White pigs, SLA-11 c.1421 + 38 CC sows produced 0.9 more pigs per litter for TNB of all parities than did TT sows (p < .05), while in DIV pigs SLA-11 c.1421 + 38 CC sows produced 0.84 and 0.7 less pigs per litter for TNB and NBA of all parities than did TT sows (p < .05). I am a teacher at a local primary school in Lesotho. Average litter size is around 11-12 piglets/litter. High ambient temperature (30%C) will reduce boar fertility and subsequent litter size.

Litter size is an important trait in pig production, but its improvement by selection is difficult (Haley clt nl., 1988), ~~nless high pressures of selection are applied in large populations (Herment cf ill., 1994). Average live body weight of the mature boars is between 350-380 kg. Currently the breed is very popular and mostly raised commercial pig breed around the world. The choice of breed can have a bearing on the potential size of litters, as some pigs have been selectively bred to produce bigger numbers. Average litter size is around 11-12 piglets/litter.

Litter size is lower than that of other breeds. The phenotypic and genetic relations between litter size traits, piglet mortality during farrowing and from birth to weaning and several statistics referring to the distribution of the birth weight within litter were analyzed. Landrace are white in color. Large White Yorkshire-Sow are good mother ,more litter size, Extensively used in India. The aim of this work was to verify whether polymorphisms in candidate genes for litter size segregate in Italian Large White (ITLW) pigs.

For any given litter, if a sow produces fewer viable piglets than she has functional teats, then little or no inter- vention is necessary, as each piglet has a chance to locate and occupy a teat. The Large White is widely used in outdoor systems and is hardy enough to cope with most conditions. Weight at Maturity in males and females. The objective of this study was to underline that litter size as a key trait of sows needs new parameters to be evaluated and to target an individual optimum. To date, selection for sow productivity in the Large White and Landrace has concentrated on litter size at birth (Mungate et al., 1999, Bolet et al., 2001, Holl and Robison, 2003). Decades of performance recording and rigorous selection has made the Large White more prolific than most rare breeds. The breed is known for having an excellent F.C.R. Large individual variation in litter size affects both production and piglet’s survival and health negatively. Good for Bacon production. 7. This difficulty for selection has renewed the interest in the components of litter size… A pig has given birth to 27 piglets, believed to be the largest litter recorded. Duroc crossbreds reached slaughter weight 7-10 days earlier than Landrace or Large White crosses, had higher carcass yields (0.4 kg), and lower backfat measurements (1-3 mm). They have an average of 9.2 pigs per litter. The developed crossbred pig variety can attain 85.48 kg body weight at slaughter age of 10 months with 8.1 litter size at birth.

It is a docile breed that is easily managed. Each pig requires adequate access to feed. A medium sized breed, sows weigh around 220kg and boars 280kg. Group housing, where group size is large (greater than 20 animals) tends to cause a reduction in litter size, especially in gilts. Prolificacy improvement was associated with an increased CV BW0 in litters from pure Large White (LW) and Landrace × Large White (LR × LW) crossbred sows. I will like us to become partners in sharing ideas. Poor access to feed produces uneven growth and condition, impairs feed conversion efficiency and increases the proportion of downgraded pigs. The Large White is widely used in outdoor systems and is hardy enough to cope with most conditions. The Large White is a large, lean white breed. Skip to main content. All groups of crossbred had higher litter size and weight, growth rate and better feed conversion efficiency than indigenous pig. Average litter size is around 11-12 piglets/litter.

Pig performance depends on their genetic merit and the environment they are raised in. Data from a French experimental herd recorded between 1990 and 1997 were used to estimate genetic parameters for individual birth and weaning weight, as well as litter size of Large White pigs using restricted maximum likelihood (REML) methodology applied to a multivariate animal model. The development of the modern performance testing programs led to an increase in worldwide demand for the Large White pig breeding stock from the United Kingdom in the early 1970s. Sows give birth to a large litter of 8–10 piglets, but some sows have been known to have litters of up to 13 piglets. of sires/dams of sows 1,980/12,926 975/5,490 No. The Large White was developed in Yorkshire during the 19th century from the local white breeds.
