“…In agreement with other studies gilts had a lower litter size than multiparous sows, which can mainly be explained by their lower BW and size (Tantasuparuk et al, 2000;Suriyasomboon et al, 2006;Bloemhof et al, 2013). With increasing parity, the number of piglets increases through an increase in ovulation rate and uterine capacity and at higher parities is reduced by age (Leenhouwers et al, 1999).…”

Although the climate in Germany is moderate, heat stress conditions may occur during summer months. However, it is unknown to what extent sow fertility and piglet survival are affected under moderate climatic conditions in indoor systems. Therefore, this study estimated effects of temperature and temperature-humidity index (THI) on sow fertility and piglet survival under practical husbandry conditions. Temperature and relative humidity were recorded in six piglet-producing farms in Lower Saxony, Germany, from July 2011 to August 2012. Based on that, the THI was calculated. In one farrowing, waiting and servicing unit of each farm two data loggers were installed. Reproductive parameters of 8279 successful inseminations and 10 369 litters including total number of piglets born, liveborn, stillborn and weaned piglets as well as pre-weaning mortality were evaluated. The effects of temperature and THI on reproductive parameters were estimated for varying periods after breeding and before and after farrowing, respectively. Average daily temperature across all units ranged from 15.6°C to 29.0°C, and average THI from 62.4 to 75.1. Season and parity significantly affected total number of piglets born, number of liveborn, stillborn and weaned piglets ( P < 0.001). The number of piglets born increased with rising temperature and THI in the 1 st week post breeding. Higher temperatures and THI values before farrowing resulted in a reduced number of liveborn piglets. Elevated temperature and THI values after farrowing were associated with a greater number of weaned piglets. The pre-weaning mortality significantly decreased with increasing temperature and THI values after farrowing ( P < 0.05). In conclusion, temperature and THI affected the reproductive performance of the sows and the survival of the piglets in different ways. While increased climatic values at the time of breeding positively affected the total number of piglets born, increased values at the time of farrowing had negative impacts on the reproductive performance of the sows. Piglets benefited from higher temperature and THI values after farrowing.

“…In contrast to the above, we found that overgrown toes in front and rear feet were associated with more live-born and weaned piglets as well as with a shorter wean-to-first service interval. The mean claw horn growth rate in sows is higher than the mean wear rate per month (6.3 mm vs 5.1 mm) (Amstel et al 2010); therefore, in higher parity sows, which are more prolific compared to younger ones (3-6 vs 1-2 parities) (Tantasuparuk et al 2000), claw overgrowth may occur simply as a function of age. The results of our study are limited to the extent that recording and scoring of lesions was based exclusively on farm personnel.…”

ABSTRACT:Claw lesions, which are nowadays very common in sows, are associated with a high risk of early culling and compromised welfare. In this study, we investigated the associations between the severity of claw lesions and three of the most important reproductive indicators, the number of live-born and weaned piglets and the wean-to-first service interval in three Greek farrow-to-finish herds. All studied sows were individually housed during their previous gestations. Sows were examined for lesions, which were scored on a severity scale, on several anatomical sites of the claws, before farrowing. Data on the examined reproductive indicators were retrieved from productivity databases of the herds. Because scoring of lesions on several claw sites resulted in many correlated variables for each sow examined, we employed factor analysis to create a smaller set of uncorrelated variables (factors) which contained all the information in the original variables and produced the corresponding factor scores. The number of live-born and weaned piglets was associated with the produced factor scores in two multivariable linear regression models, whereas the possible associations between the wean-to-first service interval and the factor scores was modelled with the use of zero-inflated negative binomial regression. The number of live-born piglets was negatively associated with factor scores representing lesions on heel (P ≤ 0.001) and sole of front feet (P = 0.019). The number of weaned piglets was also negatively associated with factor scores representing lesions on heel (P = 0.003) of any foot, on sole of front feet (P = 0.001) and on white line, sole and wall of rear feet (P = 0.008), while the wean-to-first service interval was associated with factor scores representing lesions on heel of any foot (P = 0.02), on sole of front feet (P = 0.02) and of dew claw length of front feet (P = 0.009). Our results indicate that combinations of lesions on the dorsal and ventral part of the claws, negatively affected the reproduction parameters considered, emphasising the importance of general improvement of feet health.

“…The piglets also depend on sows ability to care for new born piglets and the design sow crates for sow just enough to stand up and lie down so happens status sow piglets crushed the piglets to death [9,11]. In addition, the male piglets at this stage must be castrated after 10 d of age, and in the following days given creeffeed for piglets to restrict pathogens [9,[13][14][15]. Adjust the appropriate temperature for the sow and piglets in the demand for higher heat for piglet sow a lot [16].…”

Abstract:The aim of this study was to characterize the reproductive performance of new pig breed introduced to Central Vietnam. The data were collected on farm by field studies with 30 individuals, during a period of one year to record and register productive and reproductive indicators. The GF24 female breeding pigs imported from US for Vietnam through GreenFeed Asia were intended for reproductive performance. Results obtained for first coming heat, first mating, first litter farrowing age, pregnancy time and dry sow were as follows: 166.2 ± 2.94, 200.44 ± 2.14, 133.79 ± 2.29, 317.75 ± 2.19, 117.31 ± 0.31 and 8.27 ± 0.86 d, respectively. The average number of piglets born alive and stillbirths per litter were 11.58 ± 0.52 and 0.65 ± 0.27, respectively; both traits were affected by the parity of the sows. The individual weight at birth of piglets was 1.38 ± 0.12 kg and the number of weaned piglets was 9.58 ± 0.53. The feeding in the farms was characterized by using commercial feed (80%) and agricultural remainder (20%) as balanced feed. As a conclusion, this breed offers a potential progress in livestock for rural and industrial areas and is a contribution to the development of pig husbandry in Vietnam.
