Effect of rearing system and season on behaviour, productive performance and carcass quality of rabbit: A review

The aim of this study was to estimate the effect of feeding system on the growth rate and carcass quality of crossbred Improved Jezersko-Solčava x Texel (JSRT) lambs and to evaluate the effect of sex on these traits. The trial was conducted in nature according to the traditional rearing systems. The trial included 44 crossbred lambs, which were born and reared until the slaughter in three different flocks. In the age of 10 days suckled lambs were offered with ad libitum corresponding diets according to the feeding system. All lambs were slaughtered in seven consecutive days by the same procedure. The effect of feeding system significantly affected daily gain from birth to slaughter, EUROP carcass conformation and shoulder width. Likewise, the effect of sex significantly affected daily gain from birth to slaughter and internal fatness of carcasses. According to carcass cuts the feeding system significantly affected only the proportion of neck and leg. Considering meat quality traits, feeding system had a significant effect on the pH 45 and CIE a* values. In this study, we could speculate that more than the feeding system the growth and the carcass traits as well as meat traits were affected by the amount of the supplement.

SUMMARY1. Seventy-two individually fed pigs on six treatments were used to determine the effects on performance and in particular on carcass quality of (a) giving quantities of liquid skim-milk (preserved with formalin) in excess of those normally recommended; (b) replacing meal by skim-milk in the ration on a calculated dry-matter basis (1 gal. skim-milk equivalent to 1 · 1 lb. meal) as compared with a calculated energy basis (1 gal. skim-milk equivalent to 1 · 3 lb. meal) and (c) giving skim-milk for only a part of the growing period instead of throughout. The experimental period continued from 9–10 weeks of age until slaughter at an average live-weight of 135 lb.2. Extensive carcass measurements were taken and in addition assessment of the carcasses was made by a representative of the County Quality Pork Association and by an expert pork butcher.3. Carcasses from pigs given an all-meal diet were comparable in all respects with those from pigs given skim-milk throughout up to a maximum of either 5¼ or 10½ pints per pig per day.4. Carcasses from pigs given the highest level of skim-milk (maximum of 15¾ pints per pig per day) were superior in many respects to those on any of the other treatments, but the possibility that this was due to their slower rate of growth rather than to the high level of milk per se, is discussed.5. Pigs given skim-milk as replacement of part of their meal allowance on a calculated dry matter basis grew significantly faster than those in which the replacement was made on a calculated energy basis or than those given an all-meal diet. The importance is stressed of ensuring that in assessing the value of skim-milk for pigs the caloric value of the rations being compared is similar. The need for experiments based on actual determinations of the caloric value of the rations used is also emphasised.6. While the performance of pigs given skim-milk up to 75 lb. live-weight only was similar to that of pigs given skim-milk throughout, evidence was obtained that the quality of their carcasses was slightly inferior.7. There was some suggestion that as the level of skim-milk in the diet increased an eye muscle of a rather paler colour was produced.
