Autor: C.Y. Xie, G.J. Zhang, F.R. Zhang, S.H. Zhang, X.F. Zeng, P.A. Thacker, S.Y. Qiao

Publikováno v: Czech Journal of Animal Science, Vol 59, Iss 1, Pp 26-34 (2014)

Optimum standardized ileal digestible (SID) tryptophan (Trp) to lysine (Lys) ratio was estimated for 67-96 kg barrows fed low protein diets supplemented with crystalline amino acids (AA). One hundred and fifty Yorkshire × Landrace barrows, with an a

Effect of microbial phytase, vitamin D3, and citric acid on growth performance and phosphorus, nitrogen and calcium digestibility in growing swine

Autor: P.A Thacker, Xiangrong Che, Yuqiong Wang, Defa Li, Cao Hong

Publikováno v: Animal Feed Science and Technology. 73:173-186

Two experiments were conducted to determine the effects of feeding microbial phytase, vitamin D 3 and/or citric acid on grower pig performance and nutrient digestibility. In experiment 1, 30 crossbred pigs (23.4 kg) were fed one of five diets during

Elevation in tumour necrosis factor-alpha (TNF-α) messenger RNA levels in the uterus of pregnant gilts after oestrogen treatment

Autor: J Kendall, J.R Gordon, Z Yu, P.A Thacker

Publikováno v: Animal Reproduction Science. 50:57-67

In pigs, induction of embryonic degeneration, by exogenous oestrogens given early in gestation, has been long recognised. However, the underlying mechanisms responsible for this degeneration remain unclear. The present study was conducted to determin

Influence of an extended photoperiod on sow and litter performance

Autor: P.A Thacker, A.D Gooneratne

Publikováno v: Livestock Production Science. 24:83-88

The influence of an extended photoperiod on sow and litter performance was studied using 136 multiparous sows, randomly assigned to one of four treatments. From 1 week before parturition, until the end of lactation, two groups were exposed to a long

Growth hormone amplifies insulin-like growth factor I induced progesterone accumulation and P450scc mRNA expression

Autor: Y.P. Xu, P.A. Thacker, P.J. Chedrese

Publikováno v: Molecular and cellular endocrinology. 111(2)

The interaction of growth hormone (GH) and insulin-like growth factor I (IGF-I) in the acquisition of progesterone biosynthetic capacity were examined in cultured porcine granulosa cells. Basal progesterone production was not affected (P > 0.05) by G

EFFECTS OF VITAMIN B12 ON SERUM LIPIDS AND LIPOPROTEINS OF PIGS FED DIETS SUPPLEMENTED WITH PROPIONIC ACID OR CALCIUM PROPIONATE

Autor: J.P. Bowland, P.A. Thacker, M. Fenton

Publikováno v: Canadian Journal of Animal Science. 62:527-536

Effects of vitamin B12 supplementation of diets containing propionic acid (PA), or calcium propionate (CP) on feed intake, serum lipids and lipoproteins were studied utilizing 80 crossbred pigs averaging 22.5 kg. Diets, based on barley-soybean meal,
