Milk production and its relationship with milk composition, body and udder morphological traits in Bedouin goat reared under arid conditions

Abstract

This research aims to assess the performances of lactating Bedouin goat under arid conditions, focusing on the relationship of milk yield with body and udder morphology and growth traits. Fourteen goats and their kids were followed during early lactation (90 days post-partum). Mean daily milk yield was 0.56 kg. Milk fat, proteins, lactose, solids non-fat and minerals were respectively 34.9, 38.9, 48.8, 107 and 6.7 g L-1. Mean kids’ birth weight, adjusted body weight at 90 days of age and average daily gain were respectively 2 kg, 6.6 kg and 51.4 g day-1. Daily milk yield was correlated with goats’ body weight, withers height, rump height, udder width and udder circumference but not with linear udder score and growth performances. These results provide important data about the milk production of Bedouin goat emphasizing its correlation with body and udder morphological traits which can help to elaborate a specific breeding program for this breed.

Perbandingan produksi dan kualitas susu kambing Peranakan Ettawa pada dua peternakan yang berbeda di Kota Batu berdasarkan komposisi pakan

“…Hasil penelitin ini menujukkan bahwa produksi susu kambing Peranakan Ettawa berikisar antara 0.68±0.01 sampai dengan 0.91±0.09 kg/hari (Tabel 4). Hasil tersebut lebih tinggi dibandingkan rata-rata produksi susu harian kambing perah Badui (Arab Saudia) yaitu sebesar 0,56 kg (Kouri et al, 2019), namun lebih rendah dibandingkan kambing Baladi (Arab Saudia), yaitu 1.11 -1.63 kg/hari (El-Tarabany et al, 2018). Perbedaan komposisi tersebut diduga karena perbedaan breed, musim dan pakan.…”

“…Komposisi susu kambing perah Baladi (Arab Saudi), yaitu protein 3, 60-3,65%, lemak 3,27-3,30%, laktosa 3,85-4,09%, BK 10,99-11,29%, BKTL 7,74-7,80% (El-Tarabany et al, 2018). Komposisi susu kambing perah Badui (Arab Saudi), kandungan lemak susu, protein, laktosa, BKTL dan BK berturut-turut adalah 34,9; 38,9; 48,8; 10,7 dan 6,7 g per L (Kouri et al, 2019). Perbedaan komposisi tersebut diduga karena perbedaan breed, musim dan pakan.…”

Association Between Body and Udder Measurement Traits and Milk Yield of Holstein Cows

“…According to Youssef et al (2014), body measurements of an animal is of importance to the farmers as it can be used for feeding, administering of medication, selection for breeding and management on the farm. Kouri et al (2019), reported that body weight and udder measurements play a significant role in milk yield. Based on the authors' knowledge, there is limited evidence on relationship between body measurements, udder measurements and milk yield of Holstein cows.…”

Endocrine, energy, and lipid status during parturition and early lactation in indigenous goats native to the Algerian Sahara

“…Our laboratory has conducted several studies on this local breed, focusing on its reproductive endocrine ecophysiology and pathophysiology [2][3][4][5][6] and endocrine and metabolic response in the Saharan environment [7,8]. Recently, the performance of lactating goats based on relationships between milk yield and udder morphological traits was investigated [9]. The low milk production has been demonstrated, since the average daily milk yield was 0.56 kg, reaching its peak (0.71 kg/day) at week 6 of lactation.…”
