| Red clover-grass, Persian clover, and common fetch that are generally grown for green manuring in organic cropping cycles, are also valuable forages for the feeding of pigs. They could substitute up to 30% of concentrates (on dry matter basis) in the feeding of growing pigs without negative impact on nitrogen (N) retention. This indicates that protein and amino acids of these legumes are well digested and utilised by the pigs. However, inclusion of roughage to pig diets shifts N utilisation so that N excretion to faeces is increased while N excretion to urine is decreased. Persian clover, in particular, is an intriguing roughage for pigs as its protein contains more amino acids that that of red clover-grass or common vetch. In addition, the digestibility... |

| This experiment studied the effects of perches in furnished cages on behaviour and feed consumption of laying hens. The study used 352 Lohmann Selected Leghorn (LSL) hens. The hens were housed at 16 weeks of age in furnished cages in groups of 8 birds. The experiment lasted for 205 days. The treatments were: perches present from 16 weeks of age (P16), perches present from 19 weeks of age (P19), and no perches present (NP). Feed consumption and egg production were measured over the pre-laying period and six 4-week laying periods. The number of hens on perch, in nest and litter box was recorded at various ages. The behaviour of 3 hens per treatment was observed using instantaneous sampling at every 5 minutes, so that the observations of each hen covered one... |

| Both digestibility and performance experiments were carried out to evaluate the nutritive value of triticale for growing-finishing pigs.In experiment 1,the apparent ileal and faecal digestibility of nutrients in barley (Hordeum vulgare cv.Viivi)and two triticale (Tritico secale cultivars, Moreno and Ulrika, were measured using six cannulated barrows with a body weight (BW)of 82-107 kg.In experiment 2,132 pigs were used over 25-100 kg BW to study the effects of replacing barley in a barley-soyabean meal-based diet with graded amounts of triticale cv.Moreno (25,50,75,or 100%) and cv.Ulrika (50 or 100%).The apparent ileal and faecal digestibilities of dry matter and organic matter were higher for both triticale cultivars than for barley (P <0.05).The... |
