“…The chi-square test also shows no significant difference in piglet mortality between indigenous and exotic breeds due to parity of dam. The study contradicts the study of Daza et al (1999) and Li et al (2010) who had reported that piglet mortality rate increased by parity order. This study has previously stated that the average pre-weaning piglet mortality was 15.62%.…”

The study was purposively taken up with the objective to find out the patterns of pre-weaning piglet mortality and economic losses in field condition. The study was purposively taken up in Gorkhaland Territorial Administration area where pig farming is a common practice. The study shows that overall pre-weaning piglet mortality was 15.62% where it was slightly higher in exotic than indigenous breed. Highest pre-weaning mortality was recorded among 0 to 15 days age group piglets mainly during winter months and in third parity of dam. The major reasons of pre-weaning piglet mortality found in the study area were chilling, piglet anemia and scouring. Overall economic losses due to pre-weaning piglet mortality were around $18696 during the last 3 years in which it was around $5453 in indigenous breed and around $13243 in exotic breeds. Economic losses due to pre-weaning piglet mortality was recorded highest for scouring, followed by chilling and low birth weight in indigenous breed, whereas it was highest for piglet anemia followed by chilling and scouring in exotic breed. Therefore, proper healthcare programme and management practices must be undertaken to avoid these huge economic losses under field condition.

“…The peak daily milk yield is reached at around 21 days of lactation [9], and general milk composition after day 7 is or secretion [3]. Sodium is also excreted primarily in the urine, with only small amounts lost in the faeces and perspiration [20].…”

Excretion of Calcium, Phosphorus, Magnesium and Sodium in Lactating Sows

et al. 2016

The aim of this study was to evaluate the excretion of calcium (Ca), phosphorus (P), magnesium (Mg) and sodium (Na) via milk, urine and faeces during the lactation period of sows. Six clinically healthy lactating sows (crossbreed Large White × Landrace) were selected for these experiments and were housed in standard conditions and fed with commercially prepared dry mixture for this category of sows. The blood serum, milk, urine and faecal samples were collected on the 7th, 14th, 21st, and 28th day of lactation. During four weeks of lactation, we recorded the relatively stable and physiological concentrations of Ca, P, Mg and Na in blood serum. The analysis of the sow’s milk showed the highest concentration of Ca and P at the end of lactation, while the highest concentration of Mg and Na was observed on the 7th lactation day. The following macro-mineral excretion was recorded in urine: 98.83-194.00 mg.l-1 for Ca; 11.88- 53.09 mg.l-1 for P; 171.67-344.05 mg.l-1 for Mg; and 56.50-74.83 mg.l-1 for Na; and in the faeces, 1824.5- 3045.5 mg.kg-1 for Ca; 1566.93-2483.2 mg.kg-1 for P; 1916.2-2505.2 mg.kg-1 for Mg; and 516.8-748.2 mg. kg-1 for Na.

“…Many publications stress the importance of birth weight for piglet survival (e.g. Fahmy, 1978;Daza 1999), suggesting to the reader that birth weight is more or less equivalent to survival. However, after phenotypic correction for birth weight, there is still considerable genetic variation for piglet survival (Knol, 2001b).…”

“…The literature on piglet survival has for quite some time and in different parts of the world recognized the (phenotypic) importance of higher birth weight for survival Fahmy, 1978;Daza 1999). Gradually, a tendency has developed to interpret this phenotypic correlation as a genetic correlation and to replace selection for increased piglet survival by a selection strategy for increased birth weight.…”
