“…It is very difficult to assure high quality and desirable physicochemical properties of raw milk designed for processing, since this is dependent on several factors which also include genetic factors such as breed [5]. Again, it was reported that some differences in the chemical composition and physicochemical properties of milk from different dairy cattle breeds are determined genetically [1], [5]. Some researchers [5] also mentioned that selection in terms of milk composition is directed towards increasing protein concentration and the protein: fat ratio.…”

“…Some researchers [5] also mentioned that selection in terms of milk composition is directed towards increasing protein concentration and the protein: fat ratio. Jersey cows have been reported to out class other exotic cows in terms of milk fat and lactose contents [1] and also in terms of milk calcium content, milk casein content and milk with bigger fat globules [5]. The quality evaluation of raw milk is usually carried out based on various tests including organoleptic test, appearance, physicochemical and bacteriological qualities.…”

Abstract:The physico-chemical and micro-biological properties of raw milk from Jersey breed cows at different stages of lactation were investigated. Raw milk samples were collected from twelve Jersey cows at the colostrum, early lactation, mid lactation and late lactation stages, at a commercial feedlot dairy farm located in Edu Local Government Area, Kwara State, Nigeria. The results showed that the Jersey cows raw milk were characterised by high physicochemical qualities. The pH ranged between 5.93 and 7.00. The ranges of specific gravity (1.11), titrable acidity (0.18 to 0.23% lactic acid), ether extract (4.83 to 6.07%) and viscosity (175.23 to 243.50 centistrokes) were observed. The Jersey cows raw milk samples were also of good microbiological qualities. Total viable bacteria counts ranged from 1.9 x 10 3 cfu/ml in the late lactation milk, 2.3 x 10 2 cfu/ml in the colostrum, 5.0 x 10 2 cfu/ml in the early lactation milk and 8.6 x 10 2 cfu/ml in the mid lactation milk. The Bacillus species and Pseudomonas species bacteria were identified. The total viable bacteria counts observed in this study are within the 2.0 x 10 5 cfu/ml bacterial count of the ISI (International Standards Index) limits for raw milk. There was no coliform organism observed in the colostrum, early lactation and mid lactation milk. Aeromonas species organism with a total coliform count of 2.3 x 10 2 cfu/ml was observed in the late lactation milk. The value of total coliform counts observed in the current study met required standard. Rhizopus species and Aspergillus species fungi with total fungal counts of between 1.3 x 10 2 cfu/ml (colostrum), 2.5 x 10 3 cfu/ml (early lactation), 3.2 x10 3 cfu/ml (late lactation) and 3.3 x 10 3 cfu/ml (mid lactation) milk were observed. It can be concluded that the raw Jersey cattle milk samples (collected from the commercial dairy farm in Edu Local Government Area, Kwara state, Nigeria) at the different stages of lactation were of good physicochemical and microbiological qualities and this may be due to maintaining better hygiene conditions.

Senegal, located in West Africa, is an example of a low-to middle-income country where the government has prioritized improving livestock production self-sufficiency, with a strong focus on dairy. Among other initiatives, the use of exotic dairy cattle has been promoted, despite no evidence for the potential livelihood benefits (or otherwise) to smallholder farmers on adopting the new genetics. The current work fills this evidence gap by performing a farm-level economic study comparing the keeping of different breed and cross-breed types of dairy cattle under different management levels. Data for the study were obtained by monitoring 220 smallholder dairy cattle farms, with a combined cattle population of about 3,000 animals, over an almost 2-yr period. Findings of the study suggest that the most net-beneficial and cost-beneficial dairy cattle enterprise that could be used by the smallholder farmers was to keep crossbred indigenous zebu by exotic Bos taurus animals under management standards that are considered good compared with local standards. This dairy enterprise type was 7.4-fold more net beneficial and had a 1.4-fold more favorable cost-benefit ratio than the traditional system of keeping indigenous zebu animals under poor (low-input) management. Interestingly, the keeping of (near) pure B. taurus dairy cattle resulted in the highest milk yields and thus benefit from milk, but was not the most net beneficial due to the high costs of keeping these animals, particularly in terms of feed. We also found that increasing the management level of any of the breed or cross-breed types under consideration, including the indigenous zebu animals, resulted in an increased net benefit of 2.2-to 2.9-fold. Results of this economic analysis are discussed as part of a broader trade-off analysis, resulting in recommendations to strengthen the Senegal dairy sector. The combined intervention of improved dairy cattle genetics and management is considered a promising intervention to improve livelihoods of the rural poor as well as livestock production self-sufficiency for Senegal; some other system constraints are addressed.

This study was conducted to determine the genetic estimates and blood traits of mixed breed of rabbits at different stages of growth. Three hundred and sixty rabbits comprising crosses of New Zealand White and Chinchilla breeds were used. Morphometric traits such as body weight, shoulder to tail length, head to shoulder length, trunk length, height at withers, ear length, heart girth, forelimb length, hind limb length and nose to shoulder length were recorded weekly. Blood samples were taken at 32 and 48 weeks to assess haematological and serum biochemical indices while physiological parameters such as rectal temperature, pulse rate and respiratory rate were determined as well. The data collected were analyzed using SAS (2008) to determine the phenotypic correlations among blood and physiological traits of mixed breed of rabbits; to estimate realized heritability and repeatability of morphometric and physiological traits. Results obtained are low to high heritability (0.13 to 0.99) and repeatability (0.07 to 0.90) estimates of morphometric and physiological parameters from mixed breeds of rabbits at different ages were obtained in this study. The high heritability estimates could be as a result of additive gene effect that gave rise to high genetic variability. The implication of this is that individual selection will lead to high genetic gain, while the repeatability of these traits being high, suggests that the likelihood to repeat these records is high. Further studies should be conducted involving larger datasets, which would yield more precise estimates of heritability and repeatability Cette étude a été menée pour déterminer les estimations génétiques et les traits sanguins de races mixtes de lapins à différents stades de croissance. Trois cent soixante lapins issus de croisements de races néo-zélandaises blanches et chinchillas ont été utilisés. Les caractéristiques morphométriques telles que le poids corporel, la longueur de l'épaule à la queue, la longueur de la tête à l'épaule, la longueur du tronc, la hauteur au garrot, la longueur des oreilles, la circonférence du cœur, la longueur des membres antérieurs, la longueur des membres postérieurs et la longueur du nez à l'épaule ont été enregistrées chaque semaine. Des échantillons de sang ont été prélevés à 32 et 48 semaines pour évaluer les indices hématologiques et biochimiques sériques, tandis que les paramètres physiologiques tels que la température rectale, le pouls et la fréquence respiratoire ont également été déterminés. Les données collectées ont été analysées à l'aide de SAS (2008) pour déterminer les corrélations phénotypiques entre les traits sanguins et physiologiques des races mixtes de lapins ; pour estimer l'héritabilité et la répétabilité réalisées des traits morphométriques et physiologiques. Les résultats obtenus sont des estimations d'héritabilité faible à élevée (0,13 à 0,99) et de répétabilité (0,07 à 0,90) des paramètres morphométriques et physiologiques de races mixtes de lapins à différents âges ont été obtenues dans cette étude. Les estimations élevées de l'héritabilité pourraient résulter d'un effet génétique additif qui a donné lieu à une forte variabilité génétique. Cela implique que la sélection individuelle entraînera un gain génétique élevé, tandis que la répétabilité de ces caractères étant élevée, cela suggère que la probabilité de répéter ces enregistrements est élevée. D'autres études devraient être menées sur des ensembles de données plus vastes, ce qui permettrait d'obtenir des estimations plus précises de l'héritabilité et de la répétabilité.
