Mash feed preparation is the widely practiced method of preparing and presenting feed to laying hens in the egg industry due to its economics, flexibility, and simplicity. However, this form of feed presents a wide range of particle sizes that are likely to segregate (i.e., large particles may separate from the small particles during feed delivery through either auger or drag-chain delivery systems). Two predominant segregation patterns were observed, including sieving and side-to-side segregation, during feed delivery. These segregation patterns promoted ingredient selection activities by the hens (mainly larger particles) that modified the nutrients in the feed and influenced the hens’ ability to meet their daily nutrient requirements. This observation was quantified through a systematic study of the relationship of feed nutrients, feed particle size distribution, and hen performance, including BW and egg quality analysis. To minimize the feed segregation effect on hen performance and egg quality, 3 recommendations are proposed to improve feed fabrication and the feed delivery system.  相似文献

A study was undertaken to develop a model for the prediction of dry matter intake by lactating Holstein Friesian dairy cows. To estimate the model parameters, a calibration dataset was compiled with the data from 32 feeding experiments conducted at 9 different sites. The database contained weekly information on 1507 lactating Holstein Friesian dairy cows regarding their diet composition and feed analysis, together with their individual voluntary feed intake, milk yield (MY), milk composition, parity, days in lactation and days pregnant.Dry matter intake was predicted from feed and animal characteristics. The feed chemical composition and digestibility can be related to feed degradation, bulk volume, intake rate, palatability and other factors influencing feed intake. Therefore, the data of standard feed analysis were used to estimate the satiety value of numerous commonly used feeds and forages. The satiety value is the measure of the extent to which a feed limits intake. The cows' ability to process the intake-limiting satiety value-units is expressed as the feed intake capacity, which is predicted from parity, days in milk and days of pregnancy which are indicators of the size and physiological state of the cow. This study shows that feed intake can be predicted using a limited number of easy-to-measure inputs that are available on commercial farms, yet reasonably biologically sound. Because the model inputs are not related to animal output (milk yield or body weight), future extension of the intake model with models for the prediction of animal performance is possible.  相似文献

Use of feed antibiotics as growth promoters for control of pathogens associated with monogastric food animal morbidity and mortality has contributed to the development of antimicrobial resistance, which has now become a threat to public health on a global scale. Presently, a number of alternative feed additives have been developed and are divided into two major categories, including 1) the ones that are supposed to directly and indirectly control pathogenic bacterial proliferation; and 2) the other ones that are intended to up-regulate host gut mucosal trophic growth, whole body growth performance and active immunity. A thorough review of literature reports reveal that efficacy responses of current alternative feed additives in replacing feed antibiotics to improve performances and gut health are generally inconsistent dependent upon experimental conditions. Current alternative feed additives typically have no direct detoxification effects on endotoxin lipopolysaccharides(LPS) and this is likely the major reason that their effects are limited. It is now understood that pathogenic bacteria mediate their negative effects largely through LPS interactions with toll-like receptor 4, causing immune responses and infectious diseases. Therefore, disruptive biological strategies and a novel and new generation of feed additives need to be developed to replace feed antibiotic growth promoters and to directly and effectively detoxify the endotoxin LPS and improve gut health and performance in monogastric food animals.  相似文献

Three experiments were conduced to quantify the potential negative effect of fine particles (<0.5 mm diameter) in the feed on fast- and slow-growing broiler growth performance. In the first experiment, chickens were fed mash or pellets of 2.5 and 4 mm diameter between 15 and 35 d of age. During this period, fast-growing broiler fed pelleted feed had a 19% higher final BW, a 12% higher feed intake, and a 12% lower (improved) feed conversion ratio than those fed mash. Feed form had no significant effect on feed intake, BW gain, or final BW of slow-growing chickens. Feed conversion ratio, however, was 6% lower with pellet than mash. In the second and the third experiments, fast and slow-growing chickens weighed 1.2 kg at the beginning of the experiment. In the second experiment, the effects of a transition from pelleted feed to mash or a mixture between the 2 feed forms on the short-term feed intake and growth was investigated. After the transition from pellet to mash or the mixture, both fast- and slow-growing chickens adapted their feed intake in less than 10 min. The mixture between mash and pellets led to a 25% higher feed intake and an 18% lower feed conversion ratio for fast-growing chickens. There was no significant difference between mash and the mixture on slow-growing feed intake, but feed conversion ratio was 9% lower. In the third experiment, the effect of fine particles concentration in the feed on short-term growth response was measured. Increase in the concentration of fine particles in the feed linearly reduced feed intake and BW gain of both fast- and slow-growing chickens. However, the slope was 5 times greater for fast-growing chickens than for slow-growing chickens. These 3 experiments showed that fast-growing chickens are more sensitive to feed form than slow-growing chickens. Therefore, physical form of the feed can be a major limiting factor of performance.  相似文献

调控猪各个阶段的采食量是动物营养研究的热点问题。风味剂主要有香味剂、甜味剂、鲜味剂,可以改善饲粮的适口性,提高猪对饲粮的喜爱程度,也可以缓解因环境变化、饲料原料改变等应激反应导致的采食量下降。猪的嗅觉系统特别发达,灵敏度很高,味觉也要比人类敏感,因此在饲粮中添加风味剂主要通过刺激猪的嗅觉和味觉来使摄食中枢兴奋,进而促进猪采食。本文综述了饲粮中添加风味剂对猪采食量的影响及其作用机理,为相关试验提供理论依据。  相似文献

Background: The feed conversion ratio(FCR) and residual feed intake(RFI) are common indexes in measuring feed efficiency for livestock. RFI is a feed intake adjusted for requirements for maintenance and production so these two traits are related. Similarly, FCR is related to feed intake and weight gain because it is their ratio. Cholecystokinin type A receptor(CCKAR) plays an important role in animal digestive process. We examined the interplay of these three parameters in a local Chinese chicken population.Results: The feed intake(FI) and body weights(BW) of 1,841 individuals were monitored on a daily basis from 56 to 105 d of age. There was a strong correlation between RFI and average daily feed intake(ADFI) and a negative correlation between the FCR and daily gain(r_g=-0.710). Furthermore, we identified 51 single nucleotide polymorphisms(SNPs) in the CCKAR and 4 of these resulted in amino acid mutations. The C334A mutation was specifically associated with FI and the expected feed intake(EFI)(P 0.01) and significantly associated with the average daily gain(ADG)(P 0.05). G1290A was significantly associated with FI and EFI(P 0.05).Conclusion: FCR is apply to weight selecting, and RFI is more appropriate if the breeding focus is feed intake. And C334A and G1290A of the CCKAR gene can be deemed as candidate markers for feed intake and weight gain.  相似文献

Intestinal dysfermentation with diarrhea, tympania and accidental cases of sudden death in the pig after liquid feeding of components highly fermentable. 6 cases of the veterinary feeding advisement of the Institute of animal nutrition are presented, which can be described with the complex of symptoms: diarrhea, bloat, sudden death. These are related to feeding technique, feed composition and hygienic quality of the feed. All techniques of feeding, causing abundant feed intake and thus an exceeding of the digestive capacity of the gut are a predisposition for fermentative disturbances. A high level of feed hygiene can only be maintained in liquid feeding systems by high efforts concerning cleaning. A reduced hygienic feed quality in all present cases was apparent. All rations had a high content of easily fermentable components (sugar, partially enzymatically predigested starch). The clinical symptoms correspond to the well known "whey-syndrome". They are however not strictly correlated to rations with high whey contents. The prophylactic procedure especially concerns the improvement of the hygienic feed quality, the feeding technique and the addition of acids.  相似文献
